S-Flex Coupling Selection Process
The selection process for figuring out the appropriate S-Flex coupling involves making use of the charts shown on the following pages. You’ll find three components to become selected, two flanges and one particular sleeve.
Info important ahead of a coupling may be chosen:
HP and RPM of Driver or operating torque
Shaft size of Driver and Driven tools and corresponding keyways
Application or equipment description
Environmental problems (i.e. excessive temperature, corrosive situations, room limitations)
Actions In Selecting An S-Flex Coupling
Stage 1: Establish the Nominal Torque in in-lb of your application by utilizing the following formula:
Nominal Torque = (HP x 63025)/RPM
Stage 2: Working with the Application Service Aspect Chart 1 choose the support factor which best corresponds for your application.
Stage 3: Calculate the Layout Torque of the application by multiplying the Nominal Torque calculated in Phase 1 by the Application Service Aspect determined in Step 2.
Style Torque = Nominal Torque x Application Services Factor
Step 4: Utilizing the Sleeve Overall performance Data Chart two select the sleeve materials which finest corresponds to your application.
Step five: Making use of the S-Flex Nominal Rated Torque Chart 3 locate the acceptable sleeve material column for your sleeve selected in Step four.
Phase six: Scan down this column for the to start with entry in which the Torque Worth within the column is higher than or equal towards the Style Torque calculated in Step 3.
Refer for the greatest RPM worth with the coupling dimension to guarantee that the application needs are met. In the event the greatest RPM worth is significantly less than the application requirement, S-Flex couplings will not be proposed to the application.
If Nominal Torque is significantly less than 1/4 of the coupling’s nominalrated torque, misalignment capacities are reduced by 1/2. Once torque worth is found, refer for the corresponding coupling dimension while in the initial column from the S-Flex Nominal Rated Torque Data Chart three .
Stage 7: Examine the application driver/driven shaft sizes for the highest bore size out there within the coupling selected. If coupling max bore will not be massive sufficient for that shaft diameter, pick the following greatest coupling that should accommodate the driver/driven shaft diameters.
Stage eight: Making use of the Item Selection tables, uncover the appropriate Keyway and Bore size essential and locate the amount.
