6 QUADRA-FLEX 4-Way Flexing Martin QUADRA-FLEX Couplings, Non Lubricated, Maintenance Free, Easy and Quick Installation Handles All Combinations of Shock, Vibration, and Misalignment Parallel Angular 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.0 on the size up to.062 on the size 6. 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 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 QUADRA- FLEX 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 /8. C-

7 Styles Available in Three Styles Type J and S Flanges Bored-to-size flanges are manufactured for a slip fit on standard shafting. Available from stock in a wide range of shaft sizes. Type B Flanges Manufactured from high strength cast iron to fit standard QD bushings in sizes 6 thru 6. Fast Coupling Disassembly Martin offers the first true drop-out spacer assembly for the 4JSC spacer coupling. The center portion of the spacer can be taken out, just as in the SC thru 4SC, by simply removing four cap screws in each hub. The couplings center section can then be lifted out and the pump gaskets exposed. Flats on the spacer hubs facilitate turning shafts with a wrench. Type SC Spacer Flange QUADRA-FLEX SC Spacer Couplings feature all standard spacing requirements for the pump industry. Spacer sizes range from sizes 4 thru 4. C-6

9 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 TPR (Sizes -2) QUADRA-FLEX couplings are usually supplied with TPR sleeves in sizes -2. TPR is a general use sleeve which combines the characteristics of both EPDM & Neoprene into one. These sleeves operate within a temperature range from -0 F to +2 F (-46 C to + C). Torsional flexibility is. EPDM (Sizes -6) QUADRA-FLEX couplings are usually supplied with EPDM rubber sleeves in sizes -6. EPDM is a general use sleeve and can operate within a temperature range from -0 F to +2 F (-4 C to + C). Torsional flexibility is. 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 (Sizes -6) Neoprene flexible sleeves are also available in sizes -4. These sleeves offer a higher resistance than EPDM and are self-extinguishing. Operating temperature range for this sleeve is 0 F to +200 F (-8 C to +9 C). Torsional flexibility is. *HYTREL (Sizes 6-4) 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 -6 F to +20 F (-4 C to +2 C). Torsional flexibility is. Note: Do not use a Hytrel sleeve as a replacement for a TPR, EPDM, or Neoprene sleeve.

10 Selection Procedure Selection Procedure When the driver is an electric motor with standard speed. Step. Determine Service Factor (SF) Symbol based on equipment listed on page C-0. Step 2. Determine proper Service Factor from chart at top of page C-0. Step. Refer to page C-2 and C- 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 2 HP standard electric motor to a lumber log haul at 0 RPM.. Service Factor Symbol H 2. Service Factor 2.0. Coupling Size 9 with TPR sleeve or 6 with Hytrel Sleeve Step 4. Select flanges from pages C- thru C-9, check coupling bore size range for proper shaft fit. NOTE: Do not oversize coupling hub will cause premature wear of element. When the driver is other than an electric motor or the speeds are different than those shown in the chart on page C-. Step. Follow steps & 2 in previous procedure. Step 2. Calculate Horsepower at 00 RPM as follows: HP at 00 RPM = HP x Service Factor x 00 coupling RPM Step. Select coupling size from Tables A or C. Find a HP equal to or greater than the HP/00 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 4 HP at 00 RPM.. Service Factor Symbol M 2. Service Factor.. HP at 00 RPM = 4 x. x 00 =.6 HP/00 RPM Refer to page C-; under column for 00 RPM the required.6 HP falls between the size (.2) and the size 8 (.8). Correct selection is size 8 with TPR sleeve. Check bore sizes for flanges on pages C- thru C-9. Maximum RPM and Allowable Misalignment Maximum Types JEM, JEMS, EM, E and N Types H and HS Size RPM Parallel Angular Parallel Angular Note: Values shown above apply if the actual torque transmitted is more than 4 the coupling rating. For lesser torque, reduce the above values by 2. C-9

25 Installation Instructions 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. 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. Step. 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. 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. Parallel 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. 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. Maximum RPM and Allowable Misalignment (Dimensions in Inches) Sleeve Max. Types JEM, EM, E and N Type H & HS Size RPM Parallel Angular Y Parallel Angular Y NOTE: Values shown above may apply if the actual torque transmitted is more than 4 the coupling rating. For lesser torque, reduce the above values by 2. Type H & HS sleeves should not be used as direct replacements for JEM or EM sleeves. Value when using 6J flanges is 2.2. 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. C-24
