S-Flex Coupling Variety Method
The assortment course of action for figuring out the appropriate S-Flex coupling necessitates employing the charts proven within the following pages. There are 3 components to become chosen, two flanges and one sleeve.
Data essential prior to a coupling is usually chosen:
HP and RPM of Driver or operating torque
Shaft size of Driver and Driven products and corresponding keyways
Application or products description
Environmental circumstances (i.e. severe temperature, corrosive conditions, space limitations)
Steps In Choosing An S-Flex Coupling
Stage one: Determine the Nominal Torque in in-lb of your application by utilizing the following formula:
Nominal Torque = (HP x 63025)/RPM
Stage 2: Using the Application Service Issue Chart 1 choose the service factor which finest corresponds for your application.
Phase three: Determine the Layout Torque of one’s application by multiplying the Nominal Torque calculated in Phase 1 from the Application Services Component established in Phase two.
Style Torque = Nominal Torque x Application Services Element
Step four: Working with the Sleeve Performance Information Chart two select the sleeve material which finest corresponds for your application.
Phase 5: Applying the S-Flex Nominal Rated Torque Chart 3 locate the ideal sleeve materials column for that sleeve chosen in Phase 4.
Phase six: Scan down this column to your first entry where the Torque Worth during the column is higher than or equal towards the Style Torque calculated in Stage three.
Refer to the optimum RPM value in the coupling dimension to be sure that the application needs are met. Should the optimum RPM value is much less than the application requirement, S-Flex couplings aren’t suggested for the application.
Note:
If Nominal Torque is less than 1/4 with the coupling’s nominalrated torque, misalignment capacities are diminished by 1/2. The moment torque worth is found, refer to your corresponding coupling size within the initial column of the S-Flex Nominal Rated Torque Information Chart three .
Phase 7: Compare the application driver/driven shaft sizes to the highest bore size available within the coupling chosen. If coupling max bore is not big ample for that shaft diameter, choose the following greatest coupling which will accommodate the driver/driven shaft diameters.
Stage 8: Working with the Item Selection tables, uncover the appropriate Keyway and Bore size required and locate the number.
