Course of action
S-Flex Coupling Assortment Approach
The variety course of action for determining the right S-Flex coupling calls for applying the charts proven to the following pages. You can find three parts to become selected, two flanges and one particular sleeve.
Facts necessary in advance of a coupling is often picked:
HP and RPM of Driver or running torque
Shaft dimension of Driver and Driven products and corresponding keyways
Application or tools description
Environmental problems (i.e. extreme temperature, corrosive circumstances, area limitations)
Steps In Picking An S-Flex Coupling
Step one: Identify the Nominal Torque in in-lb of your application through the use of the following formula:
Nominal Torque = (HP x 63025)/RPM
Phase two: Using the Application Support Element Chart 1 choose the services aspect which ideal corresponds for your application.
Phase 3: Calculate the Design and style Torque of the application by multiplying the Nominal Torque calculated in Stage 1 from the Application Service Aspect established in Phase two.
Design Torque = Nominal Torque x Application Service Factor
Step 4: Applying the Sleeve Functionality Information Chart 2 decide on the sleeve materials which best corresponds to your application.
Step five: Making use of the S-Flex Nominal Rated Torque Chart 3 find the suitable sleeve material column for that sleeve chosen in Step 4.
Step 6: Scan down this column to the first entry wherever the Torque Worth in the column is higher than or equal to your Design Torque calculated in Phase 3.
Refer to your greatest RPM value of the coupling size to guarantee that the application specifications are met. If your maximum RPM worth is significantly less compared to the application necessity, S-Flex couplings are usually not suggested to the application.
If Nominal Torque is significantly less than 1/4 of your coupling’s nominalrated torque, misalignment capacities are reduced by 1/2. The moment torque worth is found, refer to the corresponding coupling dimension during the initially column on the S-Flex Nominal Rated Torque Data Chart 3 .
Stage 7: Examine the application driver/driven shaft sizes to the maximum bore size readily available on the coupling selected. If coupling max bore isn’t huge sufficient for your shaft diameter, decide on the next greatest coupling that may accommodate the driver/driven shaft diameters.
Step 8: Working with the Item Selection tables, locate the acceptable Keyway and Bore dimension needed and locate the number.
