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) Steps In Selecting A Jaw Coupling Step 1: Determine the Nominal Torque of your application by using the following formula: Nominal Torque = in-lb = (HP x 63025) RPM Nm = (KW x 9550) RPM Step 2: Using the Application Service Factors Chart 1 (page 8) select the service factor which best corresponds to your application. Step 3: Calculate the Design Torque of your application by multiplying the Nominal Torque calculated in Step 1 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 (page 9), select the elastomer material which best corresponds to your application. Step 5: Using the Jaw Nominal Rated Torque Chart 3 (page 9), 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 3. Once this value is located, refer to the corresponding coupling size in the first column of the Jaw Nominal Rated Torque Chart 3 (page 9). List of Charts provided for Selection: ■ Chart 1– Application Service Factors (page 8) ■ Chart 2 – Spider Performance Data (page 9) ■ Chart 3 – Jaw Nominal Rated Torque (page 9) ■ Jaw Type Performance Ratings (page 22) Formulas: Nominal Torque = in-lb = (HP x 63025) RPM Nm = (KW x 9550) RPM Design Torque = Nominal Torque x Application Service Factor Refer to the maximum RPM value (page 22) 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 Lovejoy engineering for assistance. 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 driver/driven shaft diameters. Refer to Chart 3 (page 9). Step 7: Using the UPC number selection table (pages 11 or 12), find the appropriate Bore and Keyway sizes required and locate the Lovejoy UPC number. 6 #DriveLineHarmony www.jbj.co.uk/spider-couplings.html Straight Jaw Spider Couplings Selection Process
A coupling is needed to connect a 20 HP standard electric motor rated at 1,800 RPM to a rotary pump. The shaft size of the electric motor (driver) is 2.0 inches and the pump (driven) is 1.75 inches. There are no special environmental conditions and the general operating temperature is normal room temperature of 72° F. Less than 1° of misalignment is expected. Step 1: Determine the Nominal Torque: Nominal Torque = (HP x 63025) RPM = (20 x 63025) 1800 = 700.28 in-lb Step 2: Using the Application Service Factors Chart 1 (page 8), 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 1.25. The value of 1.25 is found under the application category Pumps, Rotary, column: Electric Motor w/Standard Torque in Chart 1. Step 3: Calculate the Design Torque of your application: Design Torque = Nominal Torque x Application Service Factor = 700.28 x 1.25 = 875.35 in-lb Step 4: Using the Spider Performance Data Chart 2 (page 9), select the elastomer material which best corresponds to your application. Since there are no special environmental conditions, the operating temperature is 72° F and less than 1° of angular misalignment is required, the NBR elastomer material is selected. Step 5: Using the Jaw Nominal Rated Torque Chart 3 (page 9), 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 875.35 in-lb is the size L150 with a nominal torque rating of 1,240 in-lb. Referring to page JW-20, the maximum RPM of 1,800 on the electric motor of the application does not exceed the 5,000 RPM maximum allowed for the L150 size coupling with an NBR elastomer. Step 6: Compare the application driver/driven shaft size to the maximum bore available in the coupling selected (page 9). The electric motor (driver) of this application has a shaft size of 2.0 inches and the pump (driven) has a shaft size of 1.75 inches. The L150 coupling has a maximum bore less than the driver shaft size. Continuing down the Maximum Bore column, in Chart 3 (page 9), the L190 size is found to have a maximum bore size of 2.125 and is able to accommodate the driver/driven shaft sizes. Therefore, the proper coupling size for this application is a Lovejoy L190 with an NBR elastomer. Step 7: Using the UPC number Selection table, locate the appropriate Lovejoy UPC numbers. The L Type Spider Table (page 10), and the L Type hub table (page 11), provides easy reference to the Lovejoy UPC numbers. Locate the L Type Spider Table (page 10). The spider is selected by scanning down the type column and locating the NBR (Solid) entry. Read across to the L190 column and locate the Lovejoy UPC number of 12274. This number should be prefixed with the Lovejoy UPC number of 685144. Locate the L Type Hub Table (page 11). 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 L190 column to locate the Lovejoy UPC number of 12303. This number should be prefixed with the Lovejoy UPC number of 685144. The second bore size to be located is for the 1.75 inch shaft on the pump. Scan down the Bore/Keyway column to the 1-3/4 inch bore entry. Read across to the L190 column to locate the Lovejoy UPC number of 12299. This number should be prefixed with the Lovejoy UPC number of 685144. Selection Example 7 #DriveLineHarmony www.jbj.co.uk/spider-couplings.html Straight Jaw Spider Couplings Selection Process
