Procedure
S-Flex Coupling Selection Course of action
The choice method for identifying the correct S-Flex coupling needs working with the charts proven within the following pages. You can find three components for being selected, two flanges and one sleeve.
Data essential just before a coupling may be chosen:
HP and RPM of Driver or working torque
Shaft size of Driver and Driven tools and corresponding keyways
Application or gear description
Environmental ailments (i.e. excessive temperature, corrosive circumstances, area limitations)
Steps In Picking out An S-Flex Coupling
Phase 1: Decide the Nominal Torque in in-lb of the application by using the following formula:
Nominal Torque = (HP x 63025)/RPM
Phase 2: Employing the Application Services Component Chart 1 pick the service factor which very best corresponds to your application.
Phase three: Determine the Style and design Torque of the application by multiplying the Nominal Torque calculated in Stage one from the Application Service Element determined in Phase two.
Style and design Torque = Nominal Torque x Application Support Aspect
Stage 4: Using the Sleeve Functionality Information Chart 2 pick the sleeve materials which best corresponds to your application.
Phase five: Making use of the S-Flex Nominal Rated Torque Chart 3 find the appropriate sleeve material column for that sleeve selected in Phase 4.
Phase 6: Scan down this column on the to start with entry the place the Torque Value from the column is greater than or equal to your Design Torque calculated in Step 3.
Refer for the highest RPM value from the coupling size to make sure the application necessities are met. When the optimum RPM worth is less than the application necessity, S-Flex couplings usually are not recommended for that application.
Note:
If Nominal Torque is significantly less than 1/4 of your coupling’s nominalrated torque, misalignment capacities are diminished by 1/2. After torque worth is found, refer towards the corresponding coupling dimension from the first column of your S-Flex Nominal Rated Torque Information Chart three .
Step seven: Examine the application driver/driven shaft sizes towards the maximum bore dimension accessible on the coupling picked. If coupling max bore is not big ample for that shaft diameter, pick the subsequent largest coupling that can accommodate the driver/driven shaft diameters.
Phase 8: Employing the Item Selection tables, uncover the appropriate Keyway and Bore size required and find the variety.
