More than 80,000 combinations of bore sizes. Most types available from stock in 24 hours L Type This coupling offers standard shaft-to-shaft connection for general industrial duty applications. Standard L type coupling hub materials are either sintered iron (L0-L0) or cast iron (L90-L26). Applications include power transmission to industrial equipment such as pumps, gear boxes, compressors, blowers, mixers and conveyors. Jaw Type couplings are available in 24 sizes from a minimum torque rating of. in-lbs. to a maximum torque rating of 0,004 in-lbs. and a bore range of.2 inches to inches. Vescor s standard bore program covers AGMA, SAE and DIN bore/keyway and spline bore combinations. The Jaw Type coupling is available in a variety of metal hub and insert materials. Hubs are offered in sintered metal, aluminum, bronze, steel, stainless steel and ductile iron. AL Coupling AL Type The aluminum construction means this coupling is light weight with low overhung load and low inertia. The AL type also offers excellent resistance to atmospheric conditions, so it is perfect for corrosive environment applications. C Type These couplings provide standard shaft-to-shaft connection for medium range applications. The standard coupling hub is made of cast iron. L Coupling C Coupling Elastomers in Compression Vescor offers four types of elastomer designs to allow for additional flexibility in addressing specific application requirements. One piece designs are used in the L and AL models (referred to as spiders) and multiple part load cushions are used in the C model couplings. The load cushions are in sets of 8 to 4 pieces depending on coupling size. Solid Center Spider The solid center design is the most commonly used in general power transmissions applications when the shafts of the driver and driven can be kept separate by a standard gap. Open Center Spider The open center spider design allows the shafts of the driver and driven to be positioned within a short distance. Open center spiders offer shaft positioning flexibility but have lower maximum RPM capability (0 RPM max for NBR, 600 RPM max for Urethane/Hytrel). Cushions The cushion design is available exclusively for the C Type jaw couplings. The load cushions are held in place radially by a steel collar which is attached to one of the hubs. This design allows for easy installation and removal of the load cushions. The cushion design have the same engineering purpose as the spider design but is more effective in the heavy duty applications that Type C couplings address. Snap Wrap Flexible Spider The snap wrap flexible spider design allows line spider section of the coupling to be easily installed or removed without disturbing the coupling hub. This design also allows for close shaft separations all the way up to hubs maximum bore, which is not possible with open center spiders. Maximum RPM is 0 with retaining ring. Spider Materials SOX (NBR) Rubber Nitrile Butadiene (Buna-N) Rubber, a highly flexible insert material that is oil resistant, is our standard elastomer. It resembles natural rubber in resilience and elasticity and operates effectively in temperature ranges of -40 to +22 F (-40 to +00 C). (Also applies to SXB Cushions.) Urethane Urethane has. times greater torque capacity then NBR and offers good resistance to oil and chemicals. However, this material provides less dampening effect and operates at at temperature range of -0 to +60 F (-4 to + C) Hytrel Hytrel is a flexible elastomer designed for high torque and high temperature operations. Hytrel can operate in temperatures of -60 to +20 F (- to +2 C) and has an excellent resistance to oil and chemicals. It is best used in continuous load applications rather than cycle or on/off service. Bronze Bronze is a rigid, porous, oil-impregnated metal insert exclusively for low speed (max. 20 rpm) applications requiring high torque capabilities. Bronze performance is not affected by water, oil, dirt, or extreme temperatures operates in temperatures of -40 to +40 F (-40 to +22 C). 6 JULY 0
To order this part, call Lifco Hydraulics USA Toll Free at -800-92-849 Jaw Type Coupling Selection Process The selection process for determining the proper jaw coupling size and elastomer requires using the charts shown on the following pages. There are three components to be selected, two hubs and one elastomer. When the shaft size of the driver and driven of the application are of the same diameter, the hubs selected will be the same. When shaft diameters differ, hubs selected will differ accordingly. Information necessary before a coupling can be selected: HP (or KW) and RPM or Torque of driver Shaft sizes of driver and driven equipment and corresponding keyways Application description Environmental conditions (i.e. extreme temperature, corrosive conditions, space limitations) List of charts provided for Selection Chart -Application Service Factors Chart 2-Spider Performance Data Chart -Coupling Nominal Rated Torque Formulas:Nominal Torque = in-lb = (HP x 602) RPM Nm = (KW x 90) RPM Design Torque=Nominal Torque x Application Service Factor Steps in Selecting a Jaw Coupling Step : Determine the Nominal Torque of your application by using the following formula: Nominal Torque = in-lb = HP x 602 RPM Nm = (KW x 90) RPM Step 2: Using the Application Service Factors Chart select the service factor which best corresponds to your application. Step : Calculate the Design Torque of your application by multiplying the Nominal Torque calculated in Step by the application Service Factor determined in Step. 2 Design Torque=Nominal Torque x Application Service Factor Step 4: Using the Spider Performance Data Chart 2, select the elastomer material which best corresponds to your application. Step : Using the coupling Nominal Rated Torque Chart, locate the appropriate elastomer material column for the elastomer selected in Step 4. Scan down this column to the first entry where the Torque Value in the appropriate column is greater than or equal to the Design Torque calculated in Step. Once this value is located, refer to the corresponding coupling size in the first column of the Coupling Nominal Rated Torque Chart. Refer to the maximum RPM value for this elastomer torque capability to ensure that the application requirements are met. If the requirement is not satisfied at this point, another type of coupling may be required for the application. Please consult our engineers. Step 6: Compare the application driver/driven shaft sizes to the maximum bore size available on the coupling selected. If coupling bore size is not large enough for the shaft diameter, select the next largest coupling that will accommodate the drive/driven shaft diameters. Refer to Chart. Step : Using the item Number Selection Charts, find the appropriate Bore and keyway sizes required and locate the item number. Selection Example A coupling is needed to connect a 20HP standard electric motor rated at 800 RPM to a rotary pump. The shaft sizes of the electric motor (driver) is 2.0 inches and the pump (driven) is. inches. There are no special environmental conditions and the general operating temperature is normal room temperature 2 F. Less than of misalignment is expected. Step : Determine the Nominal Torque: Nominal Torque = (HP x 602) RPM = (20 x 602) 80 = 00.28 in-lb Step 2: Using the Application Service Factor Chart, select the service factor which best corresponds to your application. The application Service Factor for an electric motor with standard torque driving a rotary pump is.2. The value of.2 is found under the application category Pumps, Rotary, column: Electric Motor w/standard Torque in Chart. Step : Calculate the Design Torque of your application: Design Torque = Nominal Torque x Application Service Factor = 00.28 x.2 = 8. in-lb Step 4: Using the Elastomer Performance Data Chart 2, select the elastomer material which best corresponds to your application. Since there are not special environmental conditions, the operating temperature is 2 F and less than of angular misalignment is required, the NBR elastomer material is selected. Step : Using the Coupling Nominal Rated Torque Chart, the NBR elastomer column is used to determine the proper coupling size. Scanning down the NBR column, the first entry to accommodate the Design Torque value of 8. in-lb is the size L0 with a nominal torque rating of,240 in-lb. Referring to the maximum RPM of 800 on the electric motor of the application does not exceed the 000 RPM maximum allowed for the L0 size coupling with an NBR elastomer. Step 6: Compare the application driver/driven shaft size to the maximum bore available in the coupling selected. The electric motor (driver) of this application has a shaft size of 2.0 inches and the pump (driven) has a shaft size of. inches. The L0 coupling has a maximum bore less than the driver shaft size. Continuing down the Maximum Bore column, in Chart, the L90 size is found to have a maximum bore size of 2.2 and is able to accommodate the driver/ driven shaft sizes. Therefore the proper coupling size for the application is a L90 coupling with an NBR elastomer. Step : Using the item number Selection charts, locate the appropriate item numbers. The L Type Coupling Elastomer Chart, and the L Type Coupling Inch Hubs Chart, provides easy reference to the item numbers. Locate the L Type Couplings Inch Hubs Elastomer Chart. The elastomer is selected by scanning down the type column and locating the NBR (Solid) entry. Read across to the L90 column and locate the item number 224. Locate the L Type coupling Inch Hubs selection chart The first bore size to be located is for the 2 inch shaft on the electric motor. Scan down the Bore/Keyway column to the 2 inch bore entry. Read across to the L90 column to locate item number of 20. The second bore size is located is for the. inch shaft on the pump. Scan down the Bore/Keyway column to the /4 inch bore entry. Read across to the L90 column to locate the item number of 2299. JULY 0 68

Splined Shafts To order this part, call Lifco Hydraulics USA Toll Free at -800-92-849 Installation Instructions for Fluid Power Applications Spline bores furnished by Vescor are provided with a special spline locking feature called Centaloc (see Fig. ). Spline shafts: For optimum spline shaft life, Vescor recommends full shaft engagement in the coupling hub.(see Fig 2.) Caution: If only partial spline shaft engagement is used, tightening of the special Centaloc spline locking feature set screw over the unused section of the spline bore will result in damage to the hub. Before tightening the Centaloc set screws, check to see if the spline shaft is engaged under the set screws.then tighten the Centaloc set screws to the recommended torque shown below. If only one of the two Centaloc set screws is used because of limited shaft engagement, please remove the unused set screw.
