Stock Drive Selection STOCK DRIVE SELECTION PROCEDURE STEP 1. DETERMINE DESIGN HORSEPOWER. Refer to “Table 1 — Service Factors” Page D-43. Determine proper service (intermittent, normal, or continuous). Find the type of driven machine most similar to your application in the left column. Then to the right, find the driver type to be used and locate the service factor under your proper service selection. DESIGN HORSEPOWER = HORSEPOWER REQUIREMENT X SERVICE FACTOR Example: From Table 1 Service Factor 1.4 HP Requirement × Service Factor = Design HP 5 × 1.4 = 7 Design HP STEP 2. DETERMINE PREFERRED BELT CROSS SECTION. The choice of belt selection type (either Hi-Cap Wedge or Conventional) is determined by conditions unique to your specific application. For advantages and disadvantages of belt section type or a recommendation for your specific application, contact your belt manufacturer. If you have a preferred type, refer to the appropriate chart below. On the horizontal axis of Table 2 or Table 3 below, locate the Design Horsepower and read up to the RPM of the Faster Shaft. The point at which the lines intersect indicates the Recommended Belt Cross Section. Example: From Table 2 3VX is chosen. (The decision to use Hi-Cap Wedge was arbitrary, conventional could have also been chosen.) STEP 3. CHECK MINIMUM SMALL (DRIVER) SHEAVE DIAMETER. Refer to Table 4. Locate intersection of given motor horsepower and speed (rpm) for recommended minimum diameter. Example: From Table 4 minimum recommended diameter is 3.00″. STEP 4. SELECT THE DRIVE A) Turn to the Stock Drive Selection Tables for the applicable belt section. B) Find the RPM of your DriveR. (Speeds shown are for full load motor ratings.) C) Read down the DriveN speed column until you reach the speed nearest your desired speed. Under the same column heading you will find the Horsepower per belt. D) Read across to the left for the required DriveR and DriveN sheaves, making sure your DriveR diameter is larger than the minimum shown in Table 4. E) Read across to the right for shaft centers nearest to your Approximate Center Distance. The belt size is shown at the top of the center distance column. Example: From Stock Drive Selection tables for 3V belts: Given: The DriveR rpm is 1750. DriveN speed is 800 rpm. Therefore: 3.04 is the HP per belt. At the far left on the same row, the sheave combination of 3.00″ DriveR and 6.50″ DriveN will provide the desired speeds. (The min. diameter from Table 4 is 3.00″.) The nearest shaft centers to the desired 20″ provided by a standard belt is 20.5″ provided by a 3VX x 560. STEP 5. DETERMINE THE NUMBER OF BELTS REQUIRED To determine the number of belts (thus, the number of grooves) multiply the horsepower per belt found in step 4C by the Arc & Length correction factor found in the center distance column below the center distance selected. This gives the corrected or actual horsepower per belt. Now divide the Design Horsepower found in step 1 by the corrected horsepower to determine the number of belts required. (Always round up to the next whole number) Design HP Example: # of Belts = Required Corrected HP Design HP found in step 1 is 7, corrected HP is found by: Horsepower per belt (step 4c) × Arc & length correction factor thus, corrected HP = 3.04 × .96 = 2.92. 7 # of belts required = = 2.4 2.92 Use 3 belts. STEP 6. Order (1) 3 3V 300 SH (driver sheave) (1) SH 15 ⁄8 (Bushing) (1) 3 3V 650 SDS (driven sheave) (1) SDS 15⁄8 (Bushing) (The decision to use QD bushings was arbitrary.)

Nonstock Drive Selection The majority of V-belt drives may be selected from the pre-engineered tables by determining the necessary components from the steps outlined in the stock drive selection procedures. If one or more non-stock components are required for your drive, or other problems are encountered in selecting stock drives, the steps outlined below in the NON STOCK DRIVE SELECTION can be used.

NOTE: ON CRUSHERS, WOOD CHIPPERS, ETC. SPECIAL CONSTRUCTION REQUIRED. CONSULT FACTORY.

TABLE 5 — SERVICE FACTORS THE CORRECT SERVICE FACTOR IS DETERMINED BY: 1. The extent and frequency of peak loads. 2. The number of operating hours per year, broken down into average hours per day of continuous service. 3. The proper service category (intermittent, normal or continuous). Select the one that most closely approximates your application conditions.

INTERMITTENT SERVICE — SERVICE FACTOR 1.0 TO 1.5 a Light Duty — Not more than 6 hours per day. b Never exceeding rated load. NORMAL SERVICE — SERVICE FACTOR 1.1 TO 1.6 a Daily service 6 to 16 hours per day. b Where occasional starting or peak load does not exceed 200% of the full load. CONTINUOUS SERVICE — SERVICE FACTOR 1.2 TO 1.8 a Where starting or peak load is in excess of 200% of the full load or where starting or peak loads and overloads occur frequently. b Continuous service 16 to 24 hours per day.

★Note: Data above the line are from National Electrical Manufacturers Association Standard MG1-3.16 and MG1-3.16a. Data below the line are a composite of Electrical Motor Manufacturers data. They are generally conservative, and specific motors and bearings may permit the use of a smaller motor sheave. Consult the motor manufacturer.

NON STOCK DRIVE SELECTION PROCDURE STEP 1. Determine Design Horsepower A. Refer to Table 5, “Typical Service Factors.” Locate the type of driven equipment and extend to the type of driver. Example: Service factor is 1.3 B. Check the list of additions for effect of idlers or other drive conditions under notes of Table 5 and correct the service factor, if applicable. Example: No additional factor C. Multiply the horsepower requirement of your drive by the corrected service factor. Example: 75 x 1.3 = 97.5 Design HP STEP 2. Choose the Belt Cross Section A. Refer to Table 6 “Hi-Cap Wedge Cross Section Selection Chart”, or to Table 7, “Conventional Cross Section Selection Chart.” Locate the design horsepower along the horizontal axis. Read up to the intersection with the RPM of the faster shaft. The point at which the lines intersect indicates the recommended belt section. Example: For 97.5 design horsepower and 1160 RPM, 5V section belts are recommended. (The decision to use Hi-Cap Wedge belts was arbitrary, conventional belts could also have been used) B. If the driver is an electric motor, check the HP and RPM against the minimum recommended sheave diameter on Table 8. Be sure to use a motor sheave that will conform to the NEMA standard for minimum sheave diameter. (If it will not, choose a larger diameter range, or a larger cross section.) Example: From Table 8, the minimum small sheave to be used for this drive is 10″

Nonstock Drive Selection STEP 3. Determine Speed Ratio Divide the RPM of faster shaft by the RPM of the slower shaft to determine your speed ratio. Example: 1160 = 2.94 Ratio 395 NOTE: If replacing a chain or gear drive, divide the number of teeth on the larger sprocket or gear by the number of teeth on the smaller. If replacing a flat belt or conventional V-belt drive, divide the diameter of the larger pulley or sheave, by the diameter of the smaller. STEP 4. Choose the Sheave Diameters Stock sheave pitch diameters are given in Table 9. If it is necessary to obtain a speed ratio not possible with two stock sheaves, it is most economical to select a standard sheave diameter for the largest sheave. A. If the diameter of one sheave is dictated by the drive, start with that diameter. If nothing limits the sheave diameters, start with “the small sheave diameter” in the upper end of the recommended driver range as given in Table 9. (If the driver is an electric motor, it is important that the motor sheave diameter is larger than given in Table 8.) Example: The largest diameter stock 5V sheave that is normally used as a driver (small) sheave has an O.D. of 16″. This is larger than the minimum 10″ as recommended for this application by Table 8. Thus 16″ is a good starting point. B. Calculate the belt speed by using this formula: Belt Speed = 0.262 x (PD of either sheave) x (RPM of same sheave). For cast iron statically balanced sheaves, the belt speed should not exceed 5000 feet per minute. Consult factory when speed exceeds 5000 fpm. Example: Belt speed = 0.262 x 15.90 x 1160 Belt speed = 4832.33 C. To determine the size of the driven sheave, multiply the O.D. of the small sheave by the speed ratio. Example: 16.0″ x 2.94 = 47.0″ NOTE: If working with the large sheave as your base, divide the O.D. of the large sheave by the speed ratio to get the small sheave O.D. D. If the large sheave is not a stock diameter (See Table 9) choose the next smaller stock diameter and divide by the speed ratio to determine a new small sheave diameter. This way only the small sheave will be made to order thus the cost of the drive may be reduced. Example: The 47.0″ O.D. is non stock, the next smaller size is 37.5″ O.D., therefore, 37.5/2.94 = 12.8″ O.D. for small sheave. (Now sheave sizes are 12.8″ O.D. driver and 37.5″ O.D. Driven.) NOTE: If small sheave O.D. is reduced by above procedure, recheck minimum electric motor driver sheave size. Also, it’s a good idea to recheck belt speed using large sheave as your base. Minimum = 10″ Belt speed = 0.262 x 37.4 x 395 = 3870.53. STEP 5. Determine Center Distance and Belt Length A. When the required center distance is not specified, use: (D + 3d) 2 , where D = O.D. of large sheave, and d = O.D. of small sheave or, use the large sheave O.D. (whichever is larger) as the preferred center distance. To calculate the belt length required when the center distance is known: (D-d)2 Belt Length = 2C + 1.57 (D + d) + 4C Where C = Center Distance Example: The required center distance specified in the original data is 36″ to 48″. So use a mean center of 42″. If there was not a C.D. specified, you could have used: D1+13d = 37.95″ as the preferred. 2 (37.5 - 12.8) 2 Belt Length = 2 x 42 + 1.57 (37.5 + 12.8) + 4 x 42 = 166.6 inches

D-150

Table 10 indicates the nearest stock belt length for 5V belts is 160 inches. Use the next step to determine the correct center distance now that the belt length is known. B. To calculate the center distance when belt length is known: Center Distance = L – 1.57 (D + d) – (D-d)2 1.57 (L – R) 2 Where D = O.D. large sheave d = O.D. small sheave C = center distance L = belt length R = speed ratio Example: Using the stock 5V1600 belt length of 160 inches: Center distance = 11(37.5 – 12.8) 211 160 – 1.57 (37.5 + 12.8) – 1.57 (160 – 2.94) 2 = 39.3 inches STEP 6. Determine Required Number of Belts A. Refer to Table 11, “Arc Correction Factor ‘G’ ”. The value representing the difference in sheave outside diameters divided by the center distance is found in the first column. Read across the column showing centers approximating those found in STEP 5 above, interpolating as necessary. This figure is your arc of contact correction factor. Example: Arc of contact correction factor is: (37.5 – 12.8) = Factor = .90 .628 39.3 By Interpretation B. Referring to the basic horsepower rating tables read down the first column of the appropriate cross section table to the RPM of the faster shaft, interpolating if the exact speed is not shown. Read across the column headed “Sheave Outside Diameter” to the diameter of your small sheave (again interpolate, if necessary) for the basic horsepower per belt. Example: The basic horsepower rating table for 5V belts indicates horsepower per belt of 27.19 (By Interpolation between 12.5 and 13.2 O.D. — where 13.20″ has HP of 28.20 and 12.50″ has HP of 26.43 then 28.20 – 26.43 = 1.77 7 x 3 + 26.43 = 27.19.) C. Continue on the same line as your horsepower per belt to the column headed “Add On HP for Speed Ratio.” Under the appropriate speed ratio column you will find the additional horsepower per belt to add for your particular speed ratio. Example: The additional HP per belt for speed ratio 2.94 is 1.26. Therefore, rated HP per belt = 27.19 + 1.26 = 28.45 D. Multiply the rated HP per belt by the belt length correction factor also found in Table 10; then by the arc correction factor found in STEP 6A. Example: Table 10 also shows the length correction factor as 1.04; therefore: corrected HP per belt = 28.45 x 1.04 x .90 = 26.63 E. Divide the design HP by the corrected HP per belt for the number of belts required. When your answer contains a fraction, round up to the next whole number. Example: .97.5. = 3.66 = 4 Belts 26.63 STEP 7. Order Martin (1) Made to order 4 5V 1280E (1) E 27⁄8 bushing (1) 4 5V 3750 F (1) F 215⁄16 bushing NOTE: The choice of QD bushings was arbitrary.

Other Driver Speeds/ Speed-Up Drives FOR SPEEDS OTHER THAN STANDARD MOTOR SPEEDS AND SPEED-UP DRIVES THE FOLLOWING PROCEDURES CAN BE USED: SPEEDS OTHER THAN STANDARD MOTOR SPEEDS: EXAMPLE A 10 HP 3000 RPM single cylinder engine with an output shaft of 11⁄4″ is to drive a rotary pump with an input shaft of 11⁄2″ at 2025 RPM. Approximate center distance is 40″, service is intermittent. STEP 1. DETERMINE THE SERVICE FACTOR, DESIGN HORSEPOWER AND BELT CROSS SECTION as detailed in stock drive selection. Example: The Service Factor is 1.2. The Design HP is 12 (10 HP x 1.2). The Belt Cross Section is 3VX. (The decision to use Hi-Cap wedge was arbitrary.) STEP 2. DETERMINE SPEED RATIO. Speed ratio = DriveR RPM DriveN RPM Example: 3000/2025 = 1.48. STEP 3. SELECT SHEAVE COMBINATION a) Turn to Stock Drive Selection chart for applicable belt cross section b) Find Speed Ratio c) Read across to find Sheave Diameter, Approximate Center Distance, Belt Number and Arc & Length Correction Factor. (If ratios given aren’t close enough to desired, turn to non stock drive design.) d) Determine Belt Speed to insure 5000 FPM (for static balancing) or 6500 FPM (for dynamically balanced) is not exceeded. Use formula: FPM = .262 x RPM x O.D. Example: From 3V drive selection chart, a 1.48 Speed Ratio utilizes a 2.80″ DriveR Sheave and a 4.12″ DriveN Sheave. A standard 3VX900 has a center distance of 39.6″ and a correction factor of 1.06. FPM = .262 x 4.12 x 2025 = 2186 STEP 4. DETERMINE BELT HORSEPOWER a) Turn to Basic Belt Horsepower rating table for applicable belt. b) Find the RPM of the faster shaft. c) Read across to the intersection of the smaller sheave diameter for the rated HP per belt. d) Continue across to the “Add-On” HP for the speed ratio. Add this value to the HP per belt. Basic HP per belt + “Add on” = Rated HP per belt. e) Multiply the HP per Belt by the Arc & Length correction factor to reach corrected HP per belt.

D-176

Rated HP x Arc & Length correction factor = corrected HP per Belt. Example: from Basic Belt Horsepower Ratings for 3VX at 3000 RPM and 2.80″ small sheave diameter for a 1.48 speed ratio, the Rated HP per Belt is 4.16. (Rated HP = 3.76 + .40 = 4.16) 4.16 x 1.06 = 4.41 = corrected HP per Belt. STEP 5. DETERMINE NUMBER OF BELTS REQUIRED. Design HP corrected HP per belt = # of belts required. Example: 12 4.41 = 2.72. Use 3 belts.

SPEED-UP DRIVES NOTE: In a Speed-Up Drive, the motor (driver) sheave is the larger sheave. Example: A 10 HP 1160 RPM, normal torque electric motor with a 15⁄8″ shaft is to drive an exhauster with a 11⁄2″ shaft at 1800 RPM. Approx. center distance is 30″. The drive will run 10 hours per day. STEP 1. SERVICE FACTOR = 1.1 (FROM TABLE 1.) Design HP = 10 x 1.1 = 11 Belt cross section = B (Decision to use B was arbitrary) STEP 2. SPEED RATIO = FASTER RPM SLOWER RPM = 1800 1160 = 1.55. STEP 3. FROM STOCK DRIVE SELECTION for B Belts at 1.55 speed ratio, the sheave combination of 4.0″ DriveR and 6.2″ DriveN is listed. (Remember, on a speed-up drive the larger sheave now becomes the driveR.) Approximate center distance is 30.4″ with a correction factor of .95 for a B75 belt. Belt speed is 1886 (.262 x 4.0 x 1800). STEP 4. FROM BASIC BELT HP RATINGS for B Belts, a 4.0 sheave at 1800 RPM has a Rated HP Per Belt of 3.6, and a corrected HP of (2.65 + .95) x .95 = 3.42). STEP 5. NUMBER OF BELTS REQUIRED = Design HP Corrected HP. 11 3.42 = 3.22. Use 4 belts.

Installation/ Tensioning V-Drives Installing A Drive

Tensioning The Drive

Here are a few suggestions to keep in mind when installing the drive:

General Rules of Tensioning: 1. Ideal tension is the lowest tension at which the belt will not slip under peak load conditions. 2. Check tension frequently during the first 24-48 hours of run-in operation. 3. Overtensioning shortens belt and bearing life. 4. Keep belts free from foreign material which may cause slip. 5. Make V-drive inspection on a periodic basis. Tension when slipping.

1. Use a matched set of belts. 2. Clean oil and grease from the sheaves; remove any rust or burrs from the sheave grooves. 3. Shorten the center distance of the drive until the belts can be put on the sheaves without forcing. 4. Make sure that the sheaves are correctly aligned, that the shafts are parallel, that there is clearance for the drive to run and that the bearings have oil. 5. Work belts around in the groove by hand, so that the slack of all belts is on the top, or slack of all belts is on the bottom.

Span L ength, t

Deflection 1 ⁄64″ per inch of span

LIKE THIS: (all slack at top)

Force

OR LIKE THIS: (all slack at bottom)

Test The Tension

DO NOT APPLY THIS WAY: (with slack at top and bottom)

Do not apply with the slack of some belts on the bottom (see solid line) and the slack of others on the top (see dotted line). Since V-belts will not slide in the groove, belts thus applied will be injured when tightened for operation. Now tension the drive until only a slight bow appears on the slack side of the belts when they are operating. 6. In a day or so, when the belts have had time to seat in the grooves, re-tension the belts. All V-belt drives should be guarded in such a manner as to comply with the Williams-Steiger Occupational Safety and Health Act and with all state and local laws and the American National Standard Institute (ANSI) safety code.

D-178

If you want to check the tension in a conventional V-belt drive, use the procedure below: 1. Measure the span length, t. 2. At the center of the span (t) apply a force (perpendicular to the span) large enough to deflect the belt 1 ⁄64″ for every inch of span length. For example, the deflection of a 100 inch span would be 100⁄64 or 19⁄16 inches. 3. Compare the force you have applied with the values given in Table 12. If the force is between the values for normal tension, and 11⁄2 times normal tension, the drive tension should be satisfactory. A force below the value for normal tension indicates an undertensioned drive. If the force exceeds the value for 11⁄2 times normal tension, the drive is tighter than it needs to be. A new drive can be tightened initially to two times normal tension to allow for the normal drop in tension during run in.

Installation and Take-up Allowances After calculating a center distance from a standard pitch length, make provision for adjusting the center distance as in Table 13, to allow for installation of the belts without injury, for tensioning, and for maintenance of proper tension throughout the life of the belt.
