Recommended Lubricants & Capacities The following table indicates the types and viscosity of lubricants suitable for reducers operating at various temperatures.

Under normal environmental conditions oil changes are suggested after the initial 250 hours of operation and thereafter at regular intervals of 2500 hours or every 6 months.

Lubrication and maintenance instructions are provided with each speed reducer. These instructions should be followed for best results. It is important that the correct types of oil be used since many oils are not suitable for the lubrication of gears. Various types of gearing require different types of lubricants.

Synthetic lubricants will allow extended lubrication intervals due to its increased resistance to thermal and oxidation degradation. It is suggested that the initial oil change be made at 1500 hours and, thereafter, at 5000 hour intervals. During the initial period of operation, higher than normal operating temperatures may be seen. This is due to the initial break-in of the gear set. The temperature of Single Reduction Worm Gear Reducers may reach approximately 225°F.

The lubricant must remain free from oxidation and contamination by water or debris, since only a very thin film of oil stands between efficient operation and failure. To assure long service life, the reducer should be periodically drained (preferably while warm) and refilled to the proper level with a recommended gear oil.

CAUTION: Relubricate more frequently if drive is operated in high ambient temperatures or unusually contaminated atmosphere. High loads and operating temperatures will also require the use of frequent lubrication. * Synthetic recommendation is exclusively Klubersynth UH1 6-460, other lubrications will void warranty. + Other lubricants corresponding to AGMA/ISO numbers are available from all major oil companies. See Page 119 for lubricant interchange. ** The Klubersynth UH1 6-460 lubricant will perform at temperatures considerably higher than 225°F. However, the factory should always be con sulted prior to operating at higher temperatures, as damage may occur to oil seals and other components.

700 Series Recommended Lubricants The following table indicates the types and viscosity of lubricants suitable for reducers operating at various temperatures. Lubrication and maintenance instructions are provided with each speed reducer. These instructions should be followed for best results. It is important that the correct types of oil be used since many oils are not suitable for the lubrication of gears. Various types of gearing require different types of lubricants. The lubricant must remain free from oxidation and contamination by water or debris, since only a very thin film of oil stands between efficient operation and failure. To assure long service life, the reducer should be periodically drained (preferably while warm) and refilled to the proper level with a recommended gear oil.

Under normal environmental conditions oil changes are suggested after the initial 250 hours of operation and thereafter at regular intervals of 2500 hours or every 6 months. Synthetic lubricants will allow extended lubrication intervals due to its increased resistance to thermal and oxidation degradation. It is suggested that the initial oil change be made at 1500 hours and, thereafter, at 5000 hour intervals. During the initial period of operation, higher than normal operating temperatures may be seen. This is due to the initial break-in of the gear set. The temperature of Single Reduction Worm Gear Reducers may reach approximately 225°F.

** The Klubersynth UH1 6-460 lubricant will perform at temperatures considerably higher than 225°F. However, the factory should always be consulted prior to operating at higher temperatures as damage may occur to oil seals and other components.

Mounting Positions For Double Reduction Models Only The variety of mounting possibilities for double-reduction drives makes it impractical to illustrate positions for these models. In general, the vent filler is at the uppermost plug position, and the drain plug at the lowest possible position. The oil level must be at the approximate centerline of the uppermost gear, with the lower box completely full. The first and second reduction housings are open to one another allowing free flow of lubricant. Levels should be checked frequently on new installation to assure proper levels are maintained.

Helical Multiplier Reducer Series Features

Combination 700 and HM Series Features

• Rugged housing of fine-grained, gear-quality cast iron provides maximum strength and durability. Greater rigidity and one-piece construction ensure precise alignment of the worm and gear. This housing construction also provides superior resistance to caustic washdown solutions, plus high heat dissipation and reduced noise level. Pipe plugs allow easy fill, level and drain in any mounting position.

• High pressure angle on worm provides greater operating efficiency.

• Housings are straddle-milled top and bottom for precise alignment of horizontal and vertical bases.

• Super-finshed oil seal diameters on both input and output shafts provide extended seal life.

• Multi-position mounting flexibility - threaded bolt holes let you install the HM Series speed reducers in almost any position.

• High strength steel output shaft assures capacity for high torque and overhung loads

• Internal baffle assures positive leak-free venting. • Large oil reservoir provides highly efficient heat dissipation and lubrication for longer operating life.

P-1485-BG

• Integral input worm and shaft design made from high-strength case-hardened alloy steel. Reducer sizes 710 through 730 have pre-lubricant ball bearings: 732 through 760 have tapered roller bearings. Double lip oil seals are standard.

• High-strength bronze worm gear is straddle mounted between heavy-duty tapered roller bearings to increase thrust and overhung load capacities, sizes 713-760.

The Boston Gear PosiVent option is available in all current 700 series styles and configurations. This specially-designed internal pressure equalization system allows the gearbox to operate in all environments without the use of conventional pressure vents. The unique design comes complete with Klubersynth UH1 6-460 lubrication pre-filled for all mounting positions. Unlike competitive versions, our unique single seam design allows for easy installation and extended life. This means longer trouble-free operation with virtually no maintenance.

Speed Reducers With PosiVent® Option

USDA approved washdown finishes available in Bost-KleenTM and Stainless Bost-KleenTM The PosiVent option is ideal for material handling, food processing, medical and pharmaceutical applications. To order specify the letter “Z” after the ratio in the 700 series catalog number.

Riser Block Kit Riser blocks permit the speed reducer to be mounted in the most desirable position, i.e. high speed input shaft above the oil level. The riser blocks allow clearance over the motor without inverting the speed reducer. They are ideal for mounting on inclined conveyors for frame clearance. The kit includes Riser Block and attachment bolts. Horizontal Base must be ordered separately. Dimensions of kits assembled on units are shown on Page 35.

General Instructions 1. Align all shafts accurately. Improper alignment can result in failure. Use of flexible couplings is recommended to compensate for slight misalignment. 2. When mounting, use maximum possible bolt size and secure reducer to a rigid foundation. Periodic inspection of all bolts is recommended. 3. Auxiliary drive components (such as sprockets, gears and pulleys) should be mounted on the shafts as close as possible to the housing to minimize effects of overhung loads. Avoid force fits that might damage bearings or gears. 4. For hollow-shaft speed reducers, place speed reducer as close as possible to supporting bearing on drive shaft. Spotdrill driven shaft for setscrews in severe applications. See kit instructions for reaction rod assembly. 5. Check and record gear backlash at installation and again at regular intervals. This should be done by measuring the rotary movement of the output shaft (rotating alternately clockwise and counterclockwise) at a suitable radius while holding the input shaft stationary. Gears should be replaced when the backlash exceeds four times the measurement taken at installation.

P-1485-BG

1/12

6. Gear drives are rated for 1750 input RPM and Class I Service (Service Factor 1.0), using Klubersynth UH1 6-460 synthetic lubricant. For lower input speeds or for different service classes or lubricants, see catalog selection pages for rating information. 7. Initial operating temperatures may be higher than normal during the break-in period of the gear set. FOR MAXIMUM LIFE, DO NOT ALLOW THE SPEED REDUCER TO OPERATE CONTINUOUSLY ABOVE 225째F AT THE GEAR CASE. In the event of overheating, check for overloads or high ambient temperatures. Keep shafts and vent plugs clean to prevent foreign particles from entering seals or gear housing. 8. All reducers should be checked to see if they have been lubricated. Prelubed 700 Series reducers will have a solid plug in the vent hole which must be replaced by the vent plug at time of installation.

Boston Gear 800-825-6544

119

700 Series Worm Gear Speed Reducers NOTE • Vented oil filler plug must be located in the uppermost position. • For all mounting positions where the vented filler plug is located in a horizontal plane, the vent hole must point upward.

• For all mounting positions where the vented filler plug is located in a vertical plane, the vent hole must point toward center of housing.

• When using a speed reducer to raise or lower a load, such as in hoisting applications, provision must be made for external braking. Under no conditions should a speed reducer be considered self-locking.

• Mounting

of speed reducers in overhead positions may be hazardous. Use of external guides or supports is strongly recommended for overhead mounting.

Key Staking Instructions Lightly tap area of keyway adjacent to key. This will upset material and not allow key to move axially when assembling to speed reducer.

QC700 (Coupling Input-3-Jaw Quick Connect Type) 1.

Coat motor shaft with anti-seize compound.

2. Install motor coupling half onto motor shaft. Use a straight edge to align coupling jaw top end flush with motor shaft except 738-B9 which will be flush with bottom of jaw. Secure with set screw. 3.

Install urethane spider insert on motor coupling half.

Insert D-Bore coupling half into urethane spider element.

5. Rotate reducer input shaft so “milled flats” are either vertical or parallel. Rotate motor coupling D-Bore to match the reducer milled flats. Coat “D” flats with anti-seize compound furnished with speed reducer. 6. Insert motor assembly into reducer flange assembly. Minor rotating of the motor may be necessary to facilitate D-Bore alignment. 7. Once aligned, push motor towards reducer until properly seated against the face of the reducer flange. 8. Insert (4) hex head cap screws into the designated locations and securely tighten.

Lubrication Instructions WARNING Boston Gear speed reducers are normally shipped without lubricant. They must be filled to the proper level with the recommended lubricant for your application before operation.

The table on Page 121 indicates the type and viscosity of lubricant suitable for reducers operating at various temperatures.

Instructions for Flanged Models F700 (Quill Type Input) 1. Assemble the key to the motor shaft and coat the shaft with anti-seize compound. Insert the motor shaft into the reducer input shaft. 2. Rotate the motor to proper position and firmly secure to flange with four hex-head cap screws. RF700 (Coupling Input – 3-Jaw Type FC) 1. Coat reducer input and motor shaft with anti-seize compound. 2. Position coupling half on input shaft with shaft flush to end of coupling bore.

3. Locate remaining half on motor shaft, with 1/32" clearance between jaw surfaces. 4. Tighten setscrews securely. For reversing applications, a thread-locking compound is recommended. 5. Install coupling insert and position motor. Rotate motor to proper position and firmly secure to flange.

Lubrication and maintenance instructions are provided with each speed reducer. These instructions should be followed for best results. It is important that the proper type of oil be used since many oils are not suitable for the lubrication of gears. Various types of gearing require different types of lubricants. The lubricant must remain free from oxidation and contamination by water or debris, since only a very thin film of oil stands between efficient operation and failure. To assure long service life, the reducer should be periodically drained (preferably while warm) and refilled to the proper level with a recommended gear oil. Under normal environmental conditions oil changes are suggested after the initial 250 hours or every 6 months. Synthetic lubricants will allow extended lubrication intervals due to its increased resistance to thermal and oxidation degradation. It is suggested that the initial oil change be made at 1500 hours and, thereafter, at 5000 hour intervals. During the initial period of operation, higher than normal operating temperatures may be seen. This is due to the initial break-in of the worm gear set. The temperature of Double Reduction Worm Gear Reducers may reach 160°F and Single Reduction Worm Gear Reducers approximately 225°F.

CAUTION – If the motor does not readily seat itself, check to determine if key has moved axially along motor shaft, causing interference. Staking of the keyway adjacent to the motor key will facilitate this procedure. 120

POSITIONS

UNIT SIZE

Avoiding those positions where the high speed oil seal is immersed in oil will provide greater security against high speed input seal wear.

DOUBLE REDUCTION MODELS

The variety of mounting possibilities for double reduction drives makes it impractical to illustrate positions for these models. In general, the vent filler is at the uppermost plug position, and the drain plug at the lowest possible posiW tion. The oil level must be at the approximate centerline of the uppermost gear.

CAUTION: Relubricate more frequently if drive operated in high ambient temperatures or unusually contaminated atmosphere. High loads and operating temperatures will also require more frequent lubrication. * Synthetic recommendation is exclusively for Klubersynth UH1 6-460, the use of other lubrications will void warranty. ** The Klubersynth UH1 6-460 lubricant will perform at temperatures considerably higher than 225°F. However, the factory should always be consulted prior to operating at higher temperature as damage may occur to oil seals and other components. † Other lubricants corresponding to AGMA/ISO numbers are available from all major oil companies.

Lubricant Interchange 1. Ambient temperature is based upon 1.0 service factor. 2. Lubricants are compounded for use in worm gears. Some contain non-corrosive, extreme pressure additives. DO NOT USE lubes that contain sulphur and/or chlorine which are corrosive to bronze gears. Extreme pressure lubes, in some cases contain materials that are toxic. Avoid use of these lubes where they can result in harmful effects. If in doubt, consult your lube supplier.

800 Series In-Line Helical Gear Drives Overhung Load

Motorized Gear Drives 1. Determine application service factor from page 140, or from Application Classifications on pages 342 and 343. 2. Determine output speed required. 3. Determine HP or output torque requirement. 4. Select a speed reducer size based on output speed and horsepower requirement for given service class. 5. Check overhung load calculation.

Example Select an In-line motorized helical gear drive and motor to drive a uniformly loaded line conveyor 24 hours/day requiring 2 HP at 35 RPM. POWER REQUIREMENT 230/460 volt 3 phase 60 hertz 1. Select Service Factor Class from page 140. Service Class = II 2. Output RPM = 35 3. 2 HP 4. Select a 2 HP drive that will satisfy minimum of II service class. 5. O.H.L. = 1720 lbs. page 143 6. Order: 1 - F872B-50K-B7 (F01078) 1 - KUTF Motor Ref - page 331 for specific motor manufacturer.

If the output shaft of a gear drive is connected to the driven machine by other than a flexible coupling, an overhung load is imposed on the shaft. This load may be calculated as follows: OHL

OHL T D K

= = = =

Relocation of the load closer to the center of gear drive will also increase OHL capacity. Permissible Overhung Loads and Output Shaft Thrust Loads are listed for each reducer in the Tables on Page 143.

Both a double and triple reduction gear drive is available. The double reduction will have an economic advantage. The triple reduction should be specified when relative rotation is of concern.

800 Series In-Line Helical Gear Drives To properly select a gear drive, the following application information should be known. 1. Service Factor or AGMA Service class. 2. Output Horsepower or Torque 3. Output RPM or Ratio (Maximum Input Speed 4500 RPM) Consult Engineering for mounting positions: M2, M3, M4, M6, M7, and M9.

NOTE: The use of an auxiliary drive between the gear drive and the driven machine reduces the torque required at the output shaft in direct proportion to the auxiliary drive ratio. A 3:1 chain ratio would reduce the torque requirement at the output shaft of the gear drive to one-third, resulting in a smaller unit size selection.

SERVICE FACTOR CHART

Non-Motorized Gear Drives

1. Determine application service factor from the service factor chart on this page, or from Application Classifications on pages 342 and 343. 2. Determine design Horsepower or Torque. - Design HP = Application HP x S.F. - Design Torque = Application Torque x S.F. 3. Select a Gear drive that satisfies output RPM, service class and/or output torque requirement. Reference rating tables pages 162-171. 4. Overhung shaft load should be checked when belt or chain drives are used, to prevent premature shaft or bearing failure. Reference page 139 for calculations.

800 Series In-Line Helical Gear Drives Lubricants Lubricant and Quantity

• Sizes 832/833B and 842/843B do not require a vent plug.

Klubersynth Synthetic UH1 6-460 is recommended for the 800 Series gear drives and, at all times, the lubricant must remain free from contamination. Normal operating temperatures range between 150°F - 170°F. During the initial break-in of the gear drive, higher than normal operating temperatures may result. All gear drives are supplied filled with UH1 6-460 synthetic oil and with the quantity listed below for standard mounting position M1 or M8 or to mounting specified at time of order.

• Sizes 862/863B and 872/873B will require an oil change after 20,000 hours of operation. More frequent changes may be required when operating in high temperature ranges or unusually contaminated environments. • Satisfactory performance may be obtained in some applications with non-synthetic oils and will require more frequent changes.

If the output shaft of a gear drive is connected to the driven machine by other than a flexible coupling, an overhung load is imposed on the shaft. This load may be calculated as follows: OHL

= 2 TK D

800 Series Right Angle Helical-Worm Gear Drives To properly select a gear drive, the following application information should be known. 1. Service Factor or AGMA Service class. 2. Output Horsepower or Torque 3. Output RPM or Ratio (Maximum Input Speed 4500 RPM) Consult Engineering for mounting positions: M2, M3, M4, and M6.

NOTE: The use of an auxiliary drive between the gear drive and the driven machine reduces the torque required at the output shaft in direct proportion to the auxillary drive ratio. A 3:1 chain ratio would reduce the torque requirement at the output shaft of the gear drive to one-third, resulting in a smaller unit size selection.

Non-Motorized Gear Drives

SERVICE FACTOR CHART

1. Determine application service factor from the service factor chart on this page, or from Application Classifications on pages 342 and 343. 2. Determine design Horsepower or Torque. - Design HP = Application HP x S.F. - Design Torque = Application Torque x S.F. 3. Select a Gear drive that satisfies output RPM, service class and/or output torque requirement. 4. Overhung shaft load should be checked when belt or chain drives are used, to prevent premature shaft or bearing failure. Ref. page 188 for calculations.

800 Series Right Angle Helical-Worm Gear Drives Lubricant and Quantity Klubersynth UH1 6-460 is recommended for the 800BR Series gear drives and at all times, the lubricant must remain free from contamination. Normal operating temperatures range between 150°F - 170°F. During the initial break-in of the gear drive, higher than normal operating temperatures may result. All gear drives are supplied filled with UH1 6-460 synthetic oil and with the quantity listed below for standard mounting position M1 or to mounting specified at time of order.

• Sizes 832/833BR and 842/843BR do not require a vent plug. • Sizes 852/853BR and 862/863BR will require an oil change after 20,000 hours of operation. More frequent changes may be required when operating in high temperature ranges or unusually contaminated environments. • Satisfactory performance may be obtained in some applications with non-synthetic oils and will require more frequent changes.

800 Series Right Angle Helical-Worm Mounting Positions Horizontal Mountings STANDARD M1

H Vertical Mountings M5

- Position M1 is standard and will be supplied with oil for this position unless otherwise specified. CAUTION: Mounting of gear drives in overhead positions may be hazardous. Use of external guides or supports is strongly recommended for overhead mounting. Avoiding those positions where the high speed oil seal is immersed in oil will provide greater security against high speed input seal wear. Note: The above drawings will serve to represent both flanges and non-flanged styles.

Recommended Lubricants The following tables indicate the type and viscosity of lubricant suitable for reducers operating at various temperatures. Lubrication and maintenance instructions are provided with each speed reducer. These instructions should be followed for best results. It is important that the proper type of oil be used since many oils are not suitable for the lubrication of gears. Various types of gearing require different types of lubricants.

The lubricant must remain free from oxidation and contamination by water or debris since only a very thin film of oil stands between efficient operation and failure. To assure long service life, the reducer should be periodically drained (preferably while warm) and refilled to the proper level with a recommended gear oil. Under normal environmental conditions oil changes, are suggested after the initial 250 hours of operation, and thereafter, at regular intervals of 2500 hours or every 6 months. Synthetic lubricants will allow extended lubrication intervals due to its increased resistance to thermal and oxidation degradation. It is suggested that the initial oil change be made at 1500 hours and, thereafter, at 5000 hour intervals. During the initial period of operation, higher than normal operating temperatures may be seen. This is due to the initial break-in of the gear set. The temper ature of Helical Gear Reducers may reach 160°F.

228

Boston Gear 800-825-6544

CAUTION: Relubricate more frequently, if drive is operated in high ambient temperatures or unusually contaminated atmospheres. High loads and operating temperatures will also require more frequent relubrication. *Synthetic recommendation is exclusively for Klubersynth UH1 6-460. ‡The UH1 6-460 lubricant will perform at temperatures considerably higher than 225°F. However, the factory should always be consulted prior to operating at higher temperatures, as damage may occur to oil seals and other components.

Drain Plug must be installed in the lower most location of the housing. This plug will be on the input shaft side of the housing for positions B, C, D and A. may be either side for A. The Vented Filler Plug should be installed in the uppermost location. This plug will be on the input shaft side for positions A, C, or D, on either side for B and must be tightened into position. Level Plug position will be as indicated for horizontal positions. For vertical positions the oil level is established by an oil level distance measured from the outer surface of the housing from the oil filler hole.

Helical Multiplier Series Installation, Lubrication and Operation Instructions Warning: Boston Gear speed reducers are normally shipped without lubricant. They must be filled to the proper level with the recommended lubricant before operation. These instructions must be read thoroughly before installing or operating speed reducers. File instructions for future reference.

CAUTION • For safe operation of any gear drive, all rotating shafts and auxiliary components must be shielded to conform with applicable safety standards. You must consider overall operational system safety at all times. • When using a gear drive to raise or lower a load, such as in hoisting applications, provision must be made for external braking. Under no conditions should a speed reducer be considered self-locking. • Mounting of speed reducers in overhead positions may be hazardous. Use of external guides or supports is strongly recommended for overhead mounting.

6. Input Speeds of 1750 and lower are shown in catalog rating tables for speed reducing applications. This does not represent the maximum speed. Since speed limitation is based on pitching velocity and varies with size and ratio.

Instructions for Flanged Models HMF (Quill Type Input) 1. Assemble the key to the motor shaft and coat the shaft with anti-seize compound. Insert the motor shaft into the reducer input shaft. 2. Rotate the motor to proper position and firmly secure to flange with four hex-head cap screws.

General Instructions

CAUTION - If the motor does not readily seat itself, check to determine if key has moved axially along motor shaft, causing interference. Staking of the keyway adjacent to the motor key will facilitate this procedure.

1. When mounting, use maximum possible bolt size and secure gear drive to a rigid foundation. Periodic inspection of all bolts is recommended.

Location of Filler, Level and Drain Plugs

2. Align all shafts accurately. Improper alignment can result in failure. Use of flexible couplings is recommended to compensate for slight misalignment. 3. Arrange the drain and breather plug per your mounting position as indicated on page 228. The breather plug should also be located in the Fill position.

Helical-Multiplier reducers may be mounted in any position shown. Filler, level and drain plugs are completely interchangeable and should be arranged to suit the required mounting positions.

4. Auxiliary drive components (such as sprockets, gears and pulleys) should be mounted on the shafts as close as possible to the housing to minimize effects of overhung loads. Avoid force fits that might damage bearings or gears. 5. Gear drives are nameplated for 1750 RPM Input Speed and Class I Service. For lower Input Speeds and other Service Class, refer to catalog rating information.

200 Series Optimount® Helical Gear Speed Reducers To properly select a speed reducer, the following application information should be known. 1. Service Factor or AGMA Service class. 2. Output Horsepower or Torque 3. Output RPM or Ratio

NOTE: The use of an auxiliary drive between the speed reducer and the driven machine reduces the torque required at the output shaft in direct proportion to the auxiliary drive ratio. A 3:1 chain ratio would reduce the torque requirement at the output shaft of the reducer to onethird, resulting in a smaller unit size selection.

Non-Motorized Speed Reducer 1. Determine application service factor from table 1 or from application classification tables on pages 342 & 343. 2. Determine design Horsepower or Torque. – Design HP = Application HP x S.F. – Design Torque = Application Torque x S.F. 3. Select a Speed reducer that satisfies output RPM, service class and/or output torque requirement. Ref. rating tables pages 243-244. 4. Overhung shaft load should be checked when belt or chain drives are used, to prevent premature shaft or bearing failure. Reference page 237 for calculations.

200 Series Optimount® Helical Gear Speed Reducers Overhung Load

Motorized Speed Reducer

If the output shaft of a speed reducer is connected to the driven machine by other than a flexible coupling, an overhung load is imposed on the shaft. This load may be calculated as follows:

1. Determine application service factor from the table on page 236 or from pages 342 and 343. 2. Determine output speed required. 3. Determine HP or output torque requirement. 4. Select based on output speed and horsepower requirement for given service class. 5. Check overhung load Ref. calculation.

An overhung load greater than permissible load value may be reduced to an acceptable value by the use of a sprocket, pinion or pulley of a larger PD. Relocation of the load closer to the center of reducer will also increase OHL capacity. Permissible Overhung Loads and Output Shaft Thrust Loads are listed for each reducer in the Tables on Pages 243-244.

200 Series Optimount® Helical Gear Speed Reducers Installation, Lubrication and Operation Instructions Warning: Boston Gear speed reducers are normally shipped without lubricant. They must be filled to the proper level with the recommended lubricant before operation.

General Instructions 1. When mounting, use maximum possible bolt size and secure gear drive to a rigid foundation. Periodic inspection of all bolts is recommended. 2. Align all shafts accurately. Improper alignment can result in failure. Use of flexible couplings is recommended to compensate for slight misalignment. 3. Arrange the drain and breather plug per your mounting position as indicated on page 254. The breather plug should also be located in the Fill position. 4. Auxiliary drive components (such as sprockets, gears and pulleys) should be mounted on the shafts as close as possible to the housing to minimize effects of overhung loads. Avoid force fits that might damage bearings or gears. 5. Gear drives are nameplated for 1750 RPM Input Speed and Class I Service. For lower Input Speeds and other Service Class, refer to catalog rating information.

P-1485-BG

1/12

6. Input Speeds of 1750 and lower are shown in catalog rating tables for speed reducing applica tions. This does not represent the maximum speed. Since speed limitation is based on pitching velocity and varies with size and ratio.

Shaft Mounted Installation Mount reducer on the shaft to be driven, as close to the supporting bearing as possible, and tighten end setscrews. For installations requiring an adapter bushing, the setscrews must pass through clear ance holes in the bushing. For severe applications, the driven shaft should be spot drilled for these setscrews.

Instructions for Flanged Models F200 (Quill Type Input) 1. Assemble the key to the motor shaft and coat the shaft with anti-seize compound. Insert the motor shaft into the reducer input shaft. 2. Rotate the motor to proper position and firmly secure to flange with four hex-head cap screws. CAUTION - If the motor does not readily seat itself, check to determine if key has moved axially along motor shaft, causing interference. Staking of the keyway adjacent to the motor key will facilitate this procedure.

Location of Filler, Level and Drain Plugs Optimount reducers may be mounted in any position shown with the following exceptions: Filler, level and drain plugs are completely interchangeable and should be arranged to suit the required mounting positions. Four (4) pipe tapped holes for these plugs are located on the input shaft side of the housing and one (1) on the opposite side.

CAUTION: Relubricate more frequently, if drive is operated in high ambient temperatures or unusually contaminated atmospheres. High loads and operating temperatures will also require more frequent relubrication. * Synthetic recommendation is exclusively for Klubersynth UH1 6-460. ‡ The UH1 6-460 lubricant will perform at temperatures considerably higher than 225°F. However, the factory should always be consulted prior to operating at higher temperatures, as damage may occur to oil seals and other components.

Drain Plug must be installed in the lower most location of the housing. This plug will be on the input shaft side of the housing for positions H1, H3, H4 and V2. The opposite for position V1 and may be either side for H2. The Vented Filler Plug should be installed in the uppermost location. This plug will be on the input shaft side for positions H1, H2, or H3, on either side for H4 and must be tightened into position with the arrow pointing upward. For vertical mounting (V1 and V2), this plug must be tightened with arrow pointing toward the center. Level Plug position will be as indicated for horizontal positions. For vertical positions the oil level is established by an oil level distance measured from the outer surface of the housing from the oil filler hole. Single Reduction Size 221 226 231 239 247

600 Series Helical Gear Speed Reducers NOTE: The use of an auxiliary drive between the speed reducer and the driven machine reduces the torque required at the output shaft in direct proportion to the auxiliary drive ratio. A 3:1 chain ratio would reduce the torque requirement at the output shaft of the reducer to onethird, resulting in a smaller unit size selection.

To properly select a speed reducer, the following application information should be known. 1. Service Factor or AGMA Service class. 2. Output Horsepower or Torque 3. Output RPM or Ratio

Non-Motorized Speed Reducer 1. Determine application service factor from table 1 or from application classification tables on pages 342 & 343. 2. Determine design Horsepower or Torque. – Design HP = Application HP x S.F. – Design Torque = Application Torque x S.F. 3. Select a Speed reducer that satisfies output RPM, service class and/or output torque requirement. Ref. rating tables pages 277-282. 4. Overhung shaft load should be checked when belt or chain drives are used, to prevent premature shaft or bearing failure. Reference page 261 for calculations.

600 Series Mounting Positions & Lubrication Foot Mounted

CAUTION

Mounting of speed reducers in overhead positions may be hazardous. Use of external guides or supports is strongly recommended for overhead mounting.

Output Flange Mounted

F F

Mounting positions are the same for multiple reduction units, and for non-flanged reducers. F - Fill • - Oil Level, D - Drain. * Position 4 and 5, Level Should be 1/2" Below Top Fill.

Recommended Lubricant Synthetic lubricants are recommended for 600B Series reducers, and at all times, the lubricant must remain free from contamination. During the initial break-in of the gear set, higher than normal operating temperatures may result.

An initial oil change should be made after the first 1,500-hours of operation and at 5,000-hour intervals thereafter. Relubrication should be performed at shorter intervals if the reducer operates in high ambient temperatures or unusually contaminated environments. For operating temperatures in excess of 225°F special seal considerations may be necessary.

Selection Procedure

How to Order

Catalog ratings are based on Class I service (uniform—no shock— load, operating no more than 10 hours/day). For applications meeting these conditions selection may be made by comparing the actual load to be transmitted with the appropriate catalog rating. For other conditions selection must be made, based on an equivalent horsepower or torque, obtained by multiplying actual load by the proper service factor. Selection Procedure: 1. Determine the correct service factor using Applications Classification Chart—Pages 342 & 343. If the application is not listed, obtain service factor from Service Factor Chart, Page 343. 2. Multiply the actual output horsepower or torque by the service factor to obtain the equivalent rating required. 3. Establish input and output speed and/or gear ratio required for the enclosed drive. 4. Selection of all bevel gear drives should be based on Steps 1 through 3 using Selection Chart for desired input and output speeds (including speed increasing drives) that satisfy the required equivalent horsepower or torque.

These units may be mounted in any position. When mounting by Flanges only, at least two Flanges must be secured.

Reference Lubrication—Prelubricated for Ambient Temperature Range of 50° to 125°F.

R100/R200 Series & VR100/VR200 Series – Spiral Bevel Gear Drives Selection Procedure Catalog ratings are based on Class I service (uniform load, operating no more than 10 hours/day). For applications meeting these conditions selection may be made by comparing the actual load to be transmitted with the appropriate catalog rating. For other conditions selection must be made, based on an equivalent horsepower or torque, obtained by multiplying actual load by the proper service factor.

Selection Procedure: 1. Determine the correct service factor using the Applications Classification Chart—Pages 342 & 343. If the application is not listed, obtain service factor from Service Factor Chart, Page 343. 2. Multiply the actual output horsepower or torque by the service factor to obtain the equivalent rating required. 3. Establish input and output speed and/or gear ratio required for the enclosed drive. 4. Selection of all bevel gear drives should be based on Steps 1 through 3 using Selection Chart for desired input and output speeds (including speed increasing drives) that satisfy the required equivalent horsepower or torque.

M Lubrication

BEVEL GEAR REDUCERS

Lubrication and maintenance instructions are provided with each speed reducer. These instructions should be followed for best results. It is important that the proper type of oil be used since many oils are not suitable for the lubrication of gears. Various types of gearing require different types of lubricants. The lubricant must remain free from oxidation and contamination by water or debris since only a very thin film of oil stands between efficient operation and failure. To assure long service life, the reducer should be periodically drained (preferably while warm) and refilled to the proper level with a recommended gear oil. Under normal environmental conditions oil changes are suggested after the initial 250 hours of operation, and therefore, at regular intervals of 2500 hours or every 6 months. Synthetic lubricants will allow extended lubrication intervals due to its increased resistance to thermal and oxidation degradation. It is suggested that the initial oil change be made at 1500 hours and, thereafter, at 5000 hour intervals. During the initial period of operation, higher than normal operating temperatures may be seen. This is due to the initial break-in of the gear set. The temperature of Bevel Gear Reducers may reach approximately 225°F.

Catalog ratings are based on Class I service (uniform load, operating no more than 10 hours/day). For applications meeting these conditions selection may be made by comparing the actual load to be transmitted with the appropriate catalog rating. For other conditions selection must be made, based on an equivalent horsepower or torque, obtained by multiplying actual load by the proper service factor. Selection Procedure: 1. Determine the correct service factor using the Applications Classification Chart—Pages 342 & 343. If the application is not listed, obtain service factor from Service Factor Chart on page 343. 2. Multiply the actual output torque or HP by the service factor to obtain the equivalent rating required. 3. Establish input and output speed and/or gear ratio required for the enclosed drive. 4. Selection of all bevel gear drives should be based on Steps 1 through 3 using Selection Chart for desired input and output speeds (including speed increasing drives) that satisfy the required equivalent horsepower or torque.

R1000 Series Bevel Gear Drives – Features / Mountings Mountings Standard mounting is with all shafts horizontal to the floor. R1200 series units are provided with two pipe plugs and are non-vented. This allows the R1200 series to be mounted in any position without the need of moving plugs. Models R1211, R1216, R1416, and R1516 have (2) pipe plugs, oil vent-filler and oil drain, and should only be mounted in the horizontal position. All other models have (3) pipe plugs, oil vent-filler, level, drain, and are horizontal mount also. They may also be mounted with “X” shaft vertical down but are limited to oil vent-filler and oil level control – no oil drain plugs. Drives used in a vertical mounting application may require additional pipe plugs and/or grease fittings for proper lubrication and are considered special.

1– CLOCKWISE (CW) AND COUNTERCLOCKWISE (CCW) NOTATIONS INDICATE DIRECTION OF ROTATION OF SHAFTS WHEN FACING OUTER END OF SHAFT EXTENSIONS. 2– ARROWS SHOWN ON DRAWINGS ARE OVER THE TOP OF SHAFT EXTENSIONS.

3– THE LETTERS W, X, Y, Z SHOWN ADJACENT TO THE SHAFT EXTENSIONS ARE USED TO DESIGNATE SPECIFIC SHAFT EXTENSIONS WHEN ORDERING BOXES WITH SPECIAL SHAFTS.

The R1000 Series Right Angle Drives with forged gear teeth may have a somewhat higher noise level at the higher speed range and also more backlash as compared with our “R” and “VR” 100 and 200 Series Right Angle Spiral Gear Drives. On models where types “B”, “D” & “F” are stocked, these can be easily converted, by the customer to types “C,” “E” & “G” respectively by simply rotating the unit 180° to its opposite mounting surface and also switching the pipe plugs for vent and drain on all series except R1200. The R1200 unit is sealed and does not have a vented plug.

* Note: Top and bottom of housings are both machined surfaces. By interchanging vent plug and drain plug you can convert B to C, D to E, F to G. On R1200 series, the plugs do not require changing.

Lubrication Lubrication and maintenance instructions are provided with each speed reducer. These instructions should be followed for best results. It is important that the proper type of oil be used since many oils are not suitable for the lubrication of gears. Various types of gearing require different types of lubricants. The lubricant must remain free from oxidation and contamination by water or debris, since only a very thin film of oil stands between efficient operation and failure. To assure long service life, the reducer should be periodically drained (preferably while warm) and refilled to the proper level with a recommended gear oil. Under normal environmental conditions oil changes are suggested after the initial 250 hours of operation, and thereafter, at regular intervals of 2500 hours or every 6 months. Synthetic lubricants will allow extended lubrication intervals due to its increased resistance to thermal and oxidation degradation. It is suggested that the initial oil change be made at 1500 hours and, thereafter, at 5000 hour intervals. During the initial period of operation, higher than normal operating temperatures may be seen. This is due to the initial break-in of the gear set. The temperature of Bevel Gear Reducers may reach approximately 225°F.

CAUTION: Relubricate more frequently if drive is operated in high ambient temperatures or unusually contaminated atmospheres. High loads and operating temperatures will also require more frequent relubrication. * Synthetic recommendation is exclusively for Klubersynth UH1 6-460. ‡ The synthetic lubricant will perform at temperatures considerably higher than 225°F. However, the factory should always be consulted prior to operating at higher temperatures, as damage may occur to oil seals and other components. ** Model R1200 unit only is pre-lubricated with 5 oz of AGMA 5 EP Gear Lubricant.

PLANET POSITION AT HIGH SPEED

Operation

How Speed Changes

The input shaft drives the inner sun. The two halves of the inner suns are compressed together with cup springs creating force against the planets. The planets also contact the outer rings which are fixed within the housing. The axles of the planets are connected to the planet carrier and output shaft by bearings fitted into slots in the planet carrier. When the input shaft turns the inner sun, the planets rotate against the outer rings, thereby causing the planet carrier and output shaft to rotate.

Turning the handwheel causes the moveable outer ring (MOR) to turn. The MOR and the fixed cam ring are separated by the ball cage. The double cam action between the MOR and the fixed cam ring causes the MOR to shift axially as it rotates. The tapered planets are forced into the inner sun as the MOR shifts toward the stationary outer ring (SOR), or allows the spring action of the inner suns to force the planets away from the center line as the MOR shifts away from the SOR. Slots in the planet carrier allow the planets to move radially closer to or further from the center line. This movement, relative to the center line, alters the effective pitch diameter of the planets and the output speed. The drive may be shifted to low speed without shaft rotation, but the drive must be rotating in order to shift to a higher speed.

Overhung load is at centerline of the output shaft projection and with no thrust. When there is combined radial and thrust loading developed, the maximum allowable thrust load must NOT EXCEED 20% of the thrust load rating shown above.

2. Calculate Design Torque The design torque can be obtained by multiplying the torque to be transmitted by the appropriate service factor given in the Table. Design Torque = T x Service Factor If the power (HP) to be transmitted is known in advance, the design torque can be calculated by the following formulas: T=

63025 x HP N

T = Torque to be transmitted (LB. IN.) HP = Power to be transmitted (HP) N = Output speed (RPM) at highest speed for constant torque load and lowest speed for constant horsepower 3. Select Unit Size. Select the most suitable size to ensure that the allowable output torque will always be greater than the design torque. Size selection may be obtained from the Selection Chart or from the selection guide at right. 4. Check Overhung Load. When coupling the shafts of the unit with a motor or the driven machine, check the allowable thrust and overhung load, not to exceed values listed in the Table. Using determined output torque and RPM, select desired unit. EXAMPLE: 25 LB. IN. output torque at 900 RPM, select FMVS0075F-B5 using 1/2 Horsepower motor.

ENCLOSURES—Most applications can utilize open dripproof motors; other enclosures are listed. For information purposes, the various enclosures are defined below.

TOTALLY-ENCLOSED, NON–VENTILATED (TENV)—A totally-enclosed motor with openings closed and of sufficient size and mass to permit the necessary heat dissipation to eliminate the need for external cooling.

OPEN,DRIPPROOF—Same as open, except the construction of motor prevents the entrance of drops of liquid or particles falling on the motor at any angle not greater than 15 degrees from vertical.

TOTALLY-ENCLOSED, FAN-COOLED (TEFC)— Basically a TENV motor which has an external fan to blow cooling air over the motor. The additional cooling eliminates the necessity of a more costly oversized TENV motor. NOTE: TENV and TEFC construction are equal in all respects regarding application, temperature capabilities and performance.

TOTALLY-ENCLOSED—A motor so constructed as to prevent free exchange of air between the inside and outside of the motor case, but not air-tight.

FOR DIMENSIONS OF THESE MOTORS, SEE PAGE 333. FOR OTHER AVAILABLE MOTORS, CONSULT FACTORY.

Speed Reducer Nomenclature

AXIAL MOVEMENT – Endwise movement of input or output shafts, sometimes called endplay, is usually expressed in thousands of an inch. EFFICIENCY – The amount of output power of the reducer as compared to the amount of input power. It is usually stated as a percentage. Example: Input HP = 1 (75/100) x (100) = 75% Efficiency Output HP = .75 BACKLASH – Rotational movement of the output shaft when holding the input shaft stationary and rotating the output shaft alternately clockwise and counter clockwise. Backlash may be expressed in thousands of an inch measured at a specific radius at the output shaft. CENTER DISTANCE – On a single reduction reducer, this is the distance between the center lines of the input and output shafts. Shaft center lines may be parallel or at right angles to one another. The center distance of multiple stage reducers usually refers to the lowest speed stage (last reduction). THRUST LOAD – Forces imposed on a shaft parallel to the shaft axis. Such a force is called a thrust load. It is often encountered on shafts driving mixers, fans, blowers and similar machines. When a thrust load acts on a speed reducer, you must be sure that the thrust load rating of the reducer is high enough that it’s shafts and bearings can absorb the load. MECHANICAL RATING – The maximum power or torque that a speed reducer can transmit, based on the strength and durability of its components, is it’s mechanical rating. Obviously, the reducer may be rated no higher than the strength or durability of its weakest component. Reducers typically have a safety margin of two to three on their mechanical ratings. Thus, a reducer can withstand momentary overloads of 200300% of its mechanical rating during a startup or other brief overload situations. THERMAL RATING – The maximum power or torque that a speed reducer can transmit continuously, based on its ability to dissipate heat generated by friction, is called its thermal rating. PRIME MOVER – The machine that provides power to a drive is its prime mover. The most frequently encountered prime movers include electric motors, internal combustion engines, hydraulic motors and air motors. The type of prime mover used can affect the speed reducer during operation. For example, an electric motor runs relatively smoothly in comparison to an internal combustion engine. MOUNTING POSITION – The relationship of the input and output shafts relative to the floor line.

340

Boston Gear 800-825-6544

INPUT HORSEPOWER – The amount of power applied to the input shaft of a reducer by the prime mover is its input horsepower. It is often used as a selection basis for power transmission components, and it appears in the rating tables of drive manufacturer’s published data. Remember that input horsepower ratings represent the maximum amount of power that the reducer can safely handle. OUTPUT HORSEPOWER – The amount of power available at the output shaft of a reducer is its output horse power. Due to losses caused by inefficiency, output horsepower is always less than input horsepower. OVERHUNG LOAD – The input or the output shaft of a speed reducer can be subject to an overhung load; that is, to a force applied at right angles to the shaft, beyond its outermost bearing. Such a force is a shaft bending load resulting from a gear, pulley, sprocket or other external drive member. Besides the tendency to bend the shaft, the overhung load (that is, the radial force on the shaft) is reacted to by the shaft in it’s bearings. Therefore, the overhung load creates loads that the bearings must be able to support without damage. SERVICE FACTORS – Numbers which modify the loads which must be considered in selecting a speed reducer are called service factors. They vary with the type of service in which the reducer is to be used, the kind of prime mover involved and the duty cycle. The service factor can be a multiplier applied to the known load, which redefines the load in accordance with the conditions at which the drive will be used, or it can be a divisor applied to catalog reducer ratings, thus redefining the rating in accordance with drive conditions. The service factor is usually applied to the speed reducer, but can also be applied to the name plate rating of the prime mover. REDUCTOR® – Boston Gear’s registered trademark for a speed reducer having a projecting input shaft suitable for mounting a coupling, sprocket, pulley or gear. FLANGED REDUCTOR – Boston Gear’s name for a reductor furnished with an input flange suitable for attaching a face mounted motor. RATIOMOTOR® – Boston Gear’s registered trademark for a motorized reducer consisting of a flanged reductor and face mounted motor assembled, sometimes referred to as a gearmotor. SELF-LOCKING ABILITY – Boston 700 Series reducers, under no conditions should be considered to hold a load when at rest. BACK-DRIVING – This is the converse of self-locking. Depending upon ratio and many variables, it is difficult to predict the back-driving capability of a 700 Series reducer. Worm gear reducers are not intended to be used as speed increasers. Consult factory for backdriving applications.

Horsepower and Torque POWER is the rate of doing work. WORK is the exerting of a FORCE through a DISTANCE. ONE FOOT POUND is a unit of WORK. It is the WORK done in exerting a FORCE OF ONE POUND through a DISTANCE of ONE FOOT. THE AMOUNT OF WORK done (Foot Pounds) is the FORCE (Pounds) exerted multiplied by the DISTANCE (Feet) through which the FORCE acts. THE AMOUNT OF POWER used (Foot Pounds per Minute) is the WORK (Foot Pounds) done divided by the TIME (Minutes) required. WORK (Ft. Lbs.) TIME (Minutes)

POWER (Foot Pounds per Minute) =

If the shaft is revolved, the FORCE (W) is moved through a distance, and WORK is done. WORK (Ft. Lbs.) = W x

2πR x No. of Rev. of shaft 12

When WORK is done in a specified TIME, POWER is used. POWER (Ft. Pounds per Minute) = W x

2πR x RPM 12

Since (1) HORSEPOWER = 33,000 Ft. Pounds per Minute Horsepower (HP) = W x

2πR RPM W x R x RPM x = 12 33,000 63,025

POWER is usually expressed in terms of HORSE POWER.

but TORQUE (Inch Pounds) = FORCE (W) x RADIUS (R)

HORSEPOWER is POWER (Foot Pounds per Minute) divided by 33,000.

Therefore HORSEPOWER (HP) =

HORSEPOWER (HP) = POWER (Ft. Lbs. per Minute) 33,000 = WORK (Ft. Pounds) 33,000 x TIME (Min.) = FORCE (Lbs.) x DISTANCE (Feet) 33,000 x TIME (Min.) ILLUSTRATION OF HORSEPOWER

HP =

33,000 x 1 = 1 HP 33,000 x 1

HP =

1000 x 33 = 1 HP 33,000 x 1

TORQUE (T) is the product of a FORCE (W) in pounds, times a RADIUS (R) in inches from the center of shaft (Lever Arm) and is expressed in Inch Pounds.

R = 2"

R = 1"

W300 #

T = WR = 300 x 1 = 300 In. Lbs.

P-1485-BG

Where total reductions are small, 50 to 1 or less, HP figures are commonly used. Higher reductions require that TORQUE figures be used to select drive components, because with large reductions, a small motor can produce extremely high TORQUE at the final low speed. For example, 1/12 HP reduced to 1 RPM using the formula below and neglecting friction: HP =

TORQUE x RPM 63,025 x HP or TORQUE = 63,025 RPM

TORQUE =

FORCE(W) = 33,000 lbs.

1/12

W150 #

TORQUE (T) x RPM 63,025

63,025 x 1/12 = 5,252 In. Lbs. 1

Therefore, motors for use with large reductions should be carefully selected. Even a small motor, if stalled, can produce enough Torque to ruin the drive, unless it is protected by a shear pin or some similar device. Neglecting frictional losses, this sketch illustrates the manner in which Torque increases as speed decreases.

Application Considerations For most applications, select for running torque rather than starting torque. The AC motor will normally produce a 200 percent starting torque. The speed reducer is built to take at least 200% momentary overload to overcome normal starting inertia. The difference in the resulting cost can be startling. A 20% safety factor in selection can double the life… of the speed reducer for more economy in the long run. This rule of thumb will help compensate for unexpected shock and vibration, and add substantially to wear life. Consider “auxiliary drives” whenever possible for economy. A properly selected gear or chain drive reduction from the reducer output to the driven shaft can produce substantial savings in space and drive cost. Avoid auxiliary drives to the input shaft… unless absolutely necessary. Auxiliary reduction from the motor to the input shaft can increase the size and cost of the drive.

Hoists Worm gear reducers are ideal for many hoist applications. There are, however, certain precautions which should be exercised with what are thought to be self-locking characteristics of this reducer type. A worm gear is generally said to be self-locking or irreversible when the gear cannot drive the worm – when the lead angle of the worm is less than the friction angle and hence, reverse drive efficiency is zero. This static condition can be upset by vibrations from nearby machinery or other sources. Many worm gear reducers are not self-locking, and even a particular size and ratio, which may appear to be, cannot be depended upon for this purpose. Also, a reducer which holds the load when upward movement is stopped may not when the load inertia is moving downward and the motor is stopped. For complete locking assurance, it is recommended that

a fail-safe brake be used for such an application. Finding the required torque and drum RPM… Torque (Lb. Ins.) = (Load) x (Drum Radius) RPM = (Velocity) ÷ .2618 x (Drum Dia.)

Belt Conveyors Belt conveyor applications are one of those wherein the speed reducer is commonly overspecified. Proper application can, in many instances, result in substantial system economies. To determine the torque required here, first determine the belt pull, since this is the principal force. In calculating this, the effects of sliding friction and/or angle or inclination must be considered. Table 1 shows Application Factors which may be used in determining belt pull based upon common combinations of materials and various angles. TABLE 1.

Application Considerations Example:

An inclined belt conveyor is to carry cases of canned fruit. The belt is leather on a wood conveyor bed. Ten cases will be on the conveyor at a time, and each weighs 30 Lbs. The conveyor is inclined at 20° to the horizontal, and the head pulley diameter is 9".

How much torque is required at the head pulley?

The friction force acts at the point of contact between the rollers and the cylinder, and will be:

Select .67 as the Application Factor (Table 1)

Friction Force=(Weight)x(Friction Factor)x(Angle Factor)

Determine weight: 10 x 30 = 300 Lbs. Determine belt pull: 300 x .67 = 201 Lbs. Determine Torque: 201 x 9/2 = 201 x 4.5 = 904 Lb. Ins. RAD

RADIUS

ANGLE

Cylinders These applications deal principally with rotation of weight about a horizontal centerline. Again, they are commonly subject to reducer overspecification. The table of Rolling Friction Factors in the section on turn tables may be used, since the supporting members will be essentially the same. For Roller Supported cylinders (Figure 1), the torque required will depend on the rolling friction factor and the angle between the rollers, in addition to the weight. Assuming that the load in the cylinder is non-solid and tends to remain essentially central (or balanced). The Table below lists angle factors to be used in the calculations.

ROLLER ANGLE

Assuming the cylinder is to be driven by one of the rollers: Torque = (Friction Force) x (Radius of Roller)

Example:

A 1200 Lb. steel cylinder is resting on two pairs of steel rollers which are 4" in diameter. The cylinder is empty. The angle between rollers is 50°. How much torque is required at the roller to turn the cylinder? Select 1.10 as Angle Factor (Table 2), and .025 as Rolling Friction Factor (Table 3). Determine Friction Force: 1200 x .025 x 1.10 = 33 Lbs.

Determine Torque: 33 x 2 = 66 Lb. Ins.

45û

Horizontal Axis Supported cylinders (Figure 2), with unbal anced loads require a different approach. Assuming that the cylinder is not full, and that the material is rotated to a position about 45° from the vertical, the torque is equal to the Material Weight x “Effective Radius”.

Effective Radius = Cylinder Diameter (D) x 0.23 (1/4 full) 0.15 (1/2 full) 0.08 (3/4 full)

Example: An axis supported cylinder is 3 Ft. in diameter and is half full of semi-solids mixture weighing 400 Lbs. How much torque is required (at the axis) to rotate the cylinder? Determine the Effective Radius: .15 x (3 x 12) = 5.4 In. Calculate Torque: 400 x 5.4 = 2160 Lb. Ins.

Application Considerations Turntables

Example:

A turntable 20 feet in diameter is to rotate a 4500 Lb. automobile. A ring of steel casters (riding on steel) supports the turntable, the casters are located at a radius of 8 feet. The turntable weights 1500 Lbs. How much torque is required to drive the turntable at the axis?

BEARING SUPPORT RADIUS

Here, too, turntable applications appear to lend themselves to overspecification of the speed reducer. This type of problem involves rotation of weight in a horizontal plane, and in most cases the torque must only overcome the friction between the turntable and its supporting bearings. Assuming that the speed of rotation will be slow, the bearing loads caused by centrifugal forces (resulting from eccentric loading) may be ignored. Since in most applications, the turntable is supported by anti-friction bearings or rollers, a Table of Rolling Friction Factors is provided to be used in the following calculations.

Select .025 as Rolling Friction Factor (Table 3). Determine weight: 4500 + 1500 = 6000 Lbs. Determine Friction Force: 6000 x .025 = 150 Lbs. Determine Torque: 150 x (8 x 12) = 14,400 Lb. Ins.

Center supported turntables do not lend themselves well to calculation because the bearings are on the supporting shaft. The scale measurement of the torque will provide the most accurate value. If this is not possible, the mean radius of the bearing may be used in the above formulas with some degree of accuracy.

TABLE 3. ROLLING FRICTION FACTORS Radial Ball Bearings Roller Bearings Thrust Ball Bearings Steel Wheels on Steel Iron Rollers on Wood Iron Rollers on Asphalt

.001 .0015 .0034 .025 .13 .14

In rim supported turntables, a friction factor should

be selected on the basis of the type of supporting bearings. The load on the bearings will be the sum of the weight of the turntable itself plus the load; the friction force at the bearings is the product of the total weight and the friction factor. Force = (Total Weight x Friction Factor) Torque = (Force) x (Radius)
