Torsional

Axial

QUADRA-FLEX® couplings absorb parallel misalignment without wear and with minimal loss of energy. The amount of parallel offset handled varies by size from .015″ on the size 5 up to .062″ on the size 16. This minimizes the radial loads on bearings when parallel misalignment occurs.

Due to the flexing characteristics of the sleeve and the locking action of the teeth, QUADRA-FLEX® couplings easily handle angular misalignment up to 1 degree without any appreciable wear.

QUADRA-FLEX® sleeves are torsionally resilient and are well suited to absorbing shocks and dampening vibrations that would otherwise be transmitted between the equipment.

The axial flexibility of the sleeve allows the QUADRAFLEX® coupling to accept a limited amount of end float. This serves to reduce thrust loads transferred to bearings. QUADRA-FLEX® units will accept axial movement of approximately 1/8″.

Sleeve Selection QUADRA-FLEX ® coupling sleeves are available in four different types of compounds. These include TPR (ThermoPlastic Rubber) in types JEM, JEMS, EM; EPDM

COUPLINGS

TPR

Rubber in type E; Neoprene in type N; Hytrel in type H and HS. To determine the sleeve best suited for the application, the material characteristics are given below.

NEOPRENE

EPDM

(Sizes 3-12)

(Sizes 13-16)

(Sizes 11-16)

QUADRA-FLEX® couplings are usually supplied with TPR sleeves in sizes 3-12. TPR is a general use sleeve which combines the characteristics of both EPDM & Neoprene into one. These sleeves operate within a temperature range from -50° F to +275° F (-46° C to +135° C). Torsional flexibility is 15°.

QUADRA-FLEX® couplings are usually supplied with EPDM rubber sleeves in sizes 13-16. EPDM is a general use sleeve and can operate within a temperature range from -30° F to +275° F (-34° C to +135° C). Torsional flexibility is 15°.

Neoprene flexible sleeves are also available in sizes 11-14. These sleeves offer a higher resistance than EPDM and are self-extinguishing. Operating temperature range for this sleeve is 0° F to +200° F (-18° C to +93° C). Torsional flexibility is 15°.

*HYTREL® (Sizes 6-14) Hytrel sleeves are molded specifically for high torque applications. The type H will transmit approximately four times as much power as an equivalent TPR, EPDM, or Neoprene sleeve. Hytrel has an operating temperature from -65° F to +250° F (-54° C to +121° C). Torsional flexibility is 7°. Note: Do not use a Hytrel sleeve as a replacement for a TPR, EPDM, or Neoprene sleeve.

Selection Procedure When the driver is an electric motor with standard speed. Step 1. Determine Service Factor (SF) Symbol based on equipment listed on page C-10. Step 2. Determine proper Service Factor from chart at top of page C-10.

When the driver is other than an electric motor or the speeds are different than those shown in the chart on page C-11. Step 1. Follow steps 1 & 2 in previous procedure. Step 2. Calculate Horsepower at 100 RPM as follows: HP at 100 RPM = HP x Service Factor x 100

Step 3. Refer to page C-12 and C-13 for proper selection of coupling. Based on chemical resistance and operating environment found on page C-8, select from chart the type of sleeve material. Find RPM of motor, then, in the column for service factor determined in Step 2, read down to the corresponding horsepower of motor being used as the driver. The number listed is the correct coupling size. Example: A coupling is needed to connect a 25 HP standard electric motor to a lumber log haul at 1750 RPM. 1. Service Factor Symbol — H 2. Service Factor — 2.0 3. Coupling Size — 9 with TPR sleeve or 6 with Hytrel Sleeve

coupling RPM

Step 3. Select coupling size from Tables A or C. Find a HP equal to or greater than the HP/100 RPM Step 4. Check Maximum bore to be sure that both shaft sizes do not exceed figure listed for size selected in step 4. If maximum is exceeded select the next largest size which will allow for bore size. Do not exceed maximum RPM for new size selected. Example: A bucket elevator is driven by a motor/reducer and requires a coupling to transmit 14 HP at 1300 RPM. 1. Service Factor Symbol — M 2. Service Factor — 1.5 3. HP at 100 RPM = 14 x1.5 x 100 = 1.61 HP/100 RPM 1300

Step 4. Select flanges from pages C-15 thru C-19, check coupling bore size range for proper shaft fit. ★ NOTE: Do not oversize coupling hub — will cause premature wear of element.

4. Refer to page C-11; under column for 100 RPM the required 1.61 HP falls between the size 7 (1.2) and the size 8 (1.8). Correct selection is size 8 with TPR sleeve. Check bore sizes for flanges on pages C-15 thru C-19.

Sleeves QUADRA-FLEX® Sleeves COUPLINGS

Martin flexible sleeve elements are offered in four material compounds (ThermoPlastic Rubber (TPR), EPDM, Neoprene, and Hytrel) available in three construction styles. Our EM sleeve offers the combination of EPDM’s extended temperature range as well as the higher oil resistance which Neoprene provides.

Types JEM — JEMS Type J sleeves are molded ThermoPlastic Rubber (TPR). Available in 1 piece solid (JEM), and 1 piece split, construction (JEMS). TPR material will handle higher temperature ranges as well as be oil resistant.

Type JEM

Type JEMS

Types EM — E — N Type EM, E, and N sleeves are of two piece molded construction with Retaining Ring. They are available in ThermoPlastic Rubber (Type TPR), EPDM (Type E), or Neoprene (Type N). These can be used with any type flanges within a given size range.

Type EM, E, and N

Types H & HS Martin H & HS sleeves are molded Hytrel for higher torque loading than standard EM sleeves. H & HS sleeves cannot be used with style J and B flanges. Hytrel sleeves are not a direct replacement for TPR, EPDM, or Neoprene sleeves.

TO REMOVE SLEEVE

Bushings Martin QD bushings offer convenient mounting of the flange to the shaft securely without setscrews. They are tapered and are split through both the bushing flange and taper to provide a clamp fit, eliminating wobble, vibration, and fretting corrosion. This is the same bushing used in Martin sprockets and sheaves and is readily available.

COUPLINGS

QUADRA-FLEX® Between-Shaft Spacings

Installation Instructions

COUPLINGS

Martin QUADRA-FLEX ® flanges (hubs) and elastomeric elements (sleeves) come in a wide range of sizes and types. First, determine the size and type of coupling components required. Remove all components from their boxes and loosely assemble the coupling. Do not install the wire ring on the two piece sleeves at this time. Check maximum RPM values in table against operating speeds. Martin EM sleeves are rated the same as other EPDM and Neoprene sleeves, and may be used interchangeably; however, Hytrel sleeves are rated at different values and may not be interchanged with Martin EM sleeves, or the EPDM and Neoprene sleeves. Check horsepower and torque ratings when selecting Hytrel sleeves.

Step 5. Slide loose flange on the shaft until the sleeve has seated completely in teeth of both flanges. Refer to “Y” dimension although not a critical dimension. Secure the flange to shaft and torque set screws and cap screws to correct torque values.

Parallel

Step 1. Make sure the motor driving the part or components is locked out electrically in such a manner that it cannot be started by anyone, however remote from the area. The same type of lockout procedure applies to any other driving device which may be used. Failure to follow these instructions may result in personal injury or property damage. Step 2. Prepare shafts for coupling installation. Inspect all coupling components and remove any protective coating or lubricants from bores, mating surfaces, and fasteners. Step 3. Slide one coupling flange onto each prepared shaft using key stock where required. With the QD Type B flange, it may be necessary to expand the QD bushing bore for ease of installation. Step 4. Position the flange on the shafts to acheive the approximate “Y” dimension (distance between flanges) shown in table. It is best to have equal shaft length into each flange. Tighten one flange in position, and slide the other flange sufficient distance back to install sleeve. Do not install wire ring on two piece sleeve in its final position at this time, but allow it to hang loosely in groove next to teeth.

Angular

Step 6. Check parallel alignment by placing a straight edge across the two coupling flanges and measure the maximum offset at several points around the periphery of coupling. Do not rotate coupling when taking these measurements. Refer to table for maximum allowed offset of parallel alignment. Realign the coupling if necessary. Step 7. Check angular alignment with a micrometer, vernier, or caliper. Take measurement from outside to outside of flanges at several points around the periphery of coupling. Do not rotate coupling when taking these measurements. Determine the difference between maximum and minimum dimensions and check to make sure they do not exceed the angluar figure on the table. If a correction is necessary, recheck parallel alignment.

NOTE: Values shown above may apply if the actual torque transmitted is more than 1 ⁄4 the coupling rating. For lesser torque, reduce the above values by 1⁄2. ★ Type H & HS sleeves should not be used as direct replacements for JEM or EM sleeves. † Value when using 6J flanges is 2.125.

Step 8. If the coupling employs the two-piece sleeve with wire ring, install ring in center groove of sleeve. Note: Some force may be required to seat the ring in groove. Step 9. Install protective guards and/or shields per OSHA and any other additional local or state safety codes as required. WARNING: Coupling sleeves may be forced from coupling when subjected to a severe shock load or abuse.

Roller chain couplings have a torque capacity in excess of the torque normally transmitted by shafting which falls within the coupling bore range. Select the smallest coupling which will accomodate both shafts. For a reversing operation, shock or pulsating loads, or other severe operating conditions, select the next larger coupling size. A cover should be used to assure maximum service life, particularly if the coupling operates at high speeds or under moist conditions. For proper lubrication, fill the space between the cover and the coupling with soft to medium consistency coupling grease.

Parts List and Engineering Data

Martin-Flex

Couplings Martin Flex® flexible couplings smoothly transmit power while compensating for shaft misalignment to 4°, parallel misalignment to 1/8″ and end float to 5/16″. The two piece flange design provides quick and easy installation and the elastomeric element absorbs shock and torsional vibration through a wide temperature range. COUPLINGS

Selection Procedure 1. Select the proper service factor from Chart 1. 2. Determine Design Horsepower by multiplying the Service Factor and the Drive Horsepower. 3. Locate the intercept of Shaft Speed and Design Horsepower from Chart 2. 4. Order per coupling: (2) bushings, (2) flange assemblies, (1) flexible tire element.

The service factors listed are intended only as a general guide for smooth power sources such as electric motors and steam turbines. Add 0.5 to factor for somewhat rougher power sources such as internal combustion engines of four or more cylinders, steam engines and water turbines. Where substantial shock occurs or starting or stopping is frequent as on some “inching” drives and on some reversing drives or where the power source is an internal combustion engine with less than four cylinders — consult factory. Where torsional vibrations occur as in, for example, internal combustion engines or reciprocating compressors or pump applications, check the coupling for possible development of damaging large amplitude vibrations. ** Add 0.5 to factor if without flywheel.

Coupling Safety WARNING & SAFETY REMINDER Safety must be considered a basic factor in machinery operation at all times. Most accidents are the result of carelessness or negligence. All rotating power transmission products are potentially dangerous and must be guarded by the contractor, installer, purchaser, owner, and user as required by applicable laws, regulations, standards, and good safety practice. Additional specific information must be obtained from other sources including the latest editions of American Society of Mechanical Engineers; Standard A.N.S.I. B15.1. A copy of this standard may be obtained from the American Society of Mechanical Engineers at 345 East 47th Street, New York, NY 10017 (212-705-7722). It is the responsibility of the contractor, installer, purchaser, owner, and user to install, maintain, and operate the parts or components manufactured and supplied by Sprocket & Gear, Inc., in such a manner as to comply with the Williams-Steiger Occupational Safety Act and with all state and local laws, ordinances, regulations, and the American National Standard Institute Safety Code.

CAUTION Guards, access doors, and covers must be securely fastened before operating any equipment. If parts are to be inspected, cleaned, observed, or general maintenance performed, the motor driving the part or components is to be locked out electrically in such a manner that it cannot be started by anyone, however remote from the area. Failure to follow these instructions may result in personal injury or property damage.

WARNING NOTE: CATALOG DIMENSIONS Every effort is made to keep all catalog dimensions and styles current in the catalog, however from time to time, it is necessary because of manufacturing changes to alter stock products dimensionally. If any stock product dimension or style shown in this catalog is critical to your application please consult factory for certification.
