S-Flex Assortment

S-Flex Coupling Choice Procedure
The variety method for identifying the correct S-Flex coupling involves employing the charts proven to the following pages. There are three parts for being picked, two flanges and one sleeve.
Information important ahead of a coupling could be picked:
HP and RPM of Driver or working torque
Shaft size of Driver and Driven products and corresponding keyways
Application or gear description
Environmental problems (i.e. severe temperature, corrosive problems, area limitations)
Steps In Choosing An S-Flex Coupling
Stage one: Figure out the Nominal Torque in in-lb of your application by utilizing the following formula:
Nominal Torque = (HP x 63025)/RPM
Stage two: Making use of the Application Support Aspect Chart 1 decide on the services element which most effective corresponds to your application.
Stage three: Determine the Style Torque of one’s application by multiplying the Nominal Torque calculated in Step 1 from the Application Support Factor established in Phase two.
Design Torque = Nominal Torque x Application Services Component
Stage four: Making use of the Sleeve Effectiveness Information Chart two pick the sleeve materials which most effective corresponds for your application.
Step 5: Working with the S-Flex Nominal Rated Torque Chart three find the appropriate sleeve materials column for your sleeve selected in Step four.
Phase 6: Scan down this column towards the first entry the place the Torque Worth while in the column is higher than or equal on the Design and style Torque calculated in Stage three.
Refer to the highest RPM worth with the coupling dimension to be sure the application prerequisites are met. In case the maximum RPM value is significantly less compared to the application necessity, S-Flex couplings are certainly not advisable for that application.
If Nominal Torque is less than 1/4 with the coupling’s nominalrated torque, misalignment capacities are lowered by 1/2. When torque value is found, refer to the corresponding coupling size during the initial column of your S-Flex Nominal Rated Torque Data Chart three .
Phase seven: Assess the application driver/driven shaft sizes for the greatest bore dimension accessible over the coupling selected. If coupling max bore isn’t big sufficient for that shaft diameter, decide on the next largest coupling that can accommodate the driver/driven shaft diameters.
Phase 8: Using the Item Choice tables, obtain the appropriate Keyway and Bore size essential and locate the number.
