S-Flex Assortment

S-Flex Coupling Assortment Process
The selection approach for figuring out the right S-Flex coupling demands working with the charts shown to the following pages. You will find three parts to get picked, two flanges and 1 sleeve.
Info essential prior to a coupling could be selected:
HP and RPM of Driver or working torque
Shaft size of Driver and Driven tools and corresponding keyways
Application or equipment description
Environmental disorders (i.e. extreme temperature, corrosive circumstances, space limitations)
Steps In Deciding on An S-Flex Coupling
Step one: Decide the Nominal Torque in in-lb of one’s application by using the following formula:
Nominal Torque = (HP x 63025)/RPM
Stage 2: Utilizing the Application Services Issue Chart 1 choose the service component which greatest corresponds for your application.
Step 3: Determine the Style Torque of your application by multiplying the Nominal Torque calculated in Step one from the Application Service Factor established in Stage two.
Style Torque = Nominal Torque x Application Support Component
Phase 4: Using the Sleeve Efficiency Information Chart two select the sleeve material which best corresponds for your application.
Step 5: Working with the S-Flex Nominal Rated Torque Chart 3 locate the ideal sleeve material column to the sleeve chosen in Stage four.
Stage 6: Scan down this column towards the to start with entry exactly where the Torque Value while in the column is PARALLELhigher than or equal on the Design and style Torque calculated in Phase 3.
Refer to the greatest RPM value in the coupling dimension to make certain the application necessities are met. Should the optimum RPM worth is much less than the application necessity, S-Flex couplings are not recommended to the application.
If Nominal Torque is less than 1/4 on the coupling’s nominalrated torque, misalignment capacities are decreased by 1/2. As soon as torque worth is located, refer on the corresponding coupling dimension during the initially column from the S-Flex Nominal Rated Torque Information Chart 3 .
Phase seven: Compare the application driver/driven shaft sizes for the highest bore size out there on the coupling chosen. If coupling max bore just isn’t large enough to the shaft diameter, select the next largest coupling that will accommodate the driver/driven shaft diameters.
Phase eight: Applying the Item Assortment tables, obtain the proper Keyway and Bore dimension expected and locate the amount.
