S-Flex Coupling Variety Approach
The selection approach for identifying the right S-Flex coupling requires applying the charts shown over the following pages. You will find three components to become chosen, two flanges and one particular sleeve.
Details necessary prior to a coupling is often chosen:
HP and RPM of Driver or running torque
Shaft size of Driver and Driven products and corresponding keyways
Application or gear description
Environmental situations (i.e. severe temperature, corrosive circumstances, room limitations)
Steps In Selecting An S-Flex Coupling
Step 1: Establish the Nominal Torque in in-lb of the application through the use of the following formula:
Nominal Torque = (HP x 63025)/RPM
Stage two: Working with the Application Service Factor Chart 1 decide on the services issue which ideal corresponds to your application.
Phase 3: Calculate the Style and design Torque of your application by multiplying the Nominal Torque calculated in Step 1 through the Application Service Issue established in Step 2.
Design and style Torque = Nominal Torque x Application Service Element
Step four: Applying the Sleeve Efficiency Information Chart 2 select the sleeve material which best corresponds to your application.
Step 5: Making use of the S-Flex Nominal Rated Torque Chart 3 find the ideal sleeve material column for your sleeve chosen in Stage 4.
Phase six: Scan down this column for the initial entry exactly where the Torque Worth during the column is higher than or equal towards the Design Torque calculated in Step 3.
Refer towards the greatest RPM value from the coupling dimension to ensure that the application specifications are met. If the maximum RPM value is much less than the application necessity, S-Flex couplings will not be suggested for the application.
Note:
If Nominal Torque is much less than 1/4 from the coupling’s nominalrated torque, misalignment capacities are reduced by 1/2. As soon as torque worth is located, refer towards the corresponding coupling dimension during the very first column on the S-Flex Nominal Rated Torque Information Chart 3 .
Phase 7: Review the application driver/driven shaft sizes towards the optimum bore size accessible on the coupling chosen. If coupling max bore just isn’t substantial sufficient to the shaft diameter, decide on the subsequent greatest coupling which will accommodate the driver/driven shaft diameters.
Step eight: Working with the Item Assortment tables, locate the appropriate Keyway and Bore dimension demanded and find the amount.
