S-Flex Coupling Assortment Approach
The selection procedure for figuring out the proper S-Flex coupling demands employing the charts shown on the following pages. You’ll find 3 parts to become chosen, two flanges and one particular sleeve.
Details important prior to a coupling is often selected:
HP and RPM of Driver or operating torque
Shaft size of Driver and Driven gear and corresponding keyways
Application or equipment description
Environmental problems (i.e. intense temperature, corrosive ailments, area limitations)
Methods In Deciding on An S-Flex Coupling
Stage one: Figure out the Nominal Torque in in-lb of one’s application by utilizing the following formula:
Nominal Torque = (HP x 63025)/RPM
Stage two: Utilizing the Application Service Issue Chart one choose the services component which best corresponds for your application.
Stage 3: Calculate the Style Torque of one’s application by multiplying the Nominal Torque calculated in Step 1 from the Application Support Aspect determined in Stage 2.
Design and style Torque = Nominal Torque x Application Service Issue
Step four: Applying the Sleeve Efficiency Data Chart two choose the sleeve material which ideal corresponds for your application.
Stage 5: Utilizing the S-Flex Nominal Rated Torque Chart 3 find the ideal sleeve material column to the sleeve selected in Stage 4.
Stage six: Scan down this column for the very first entry exactly where the Torque Worth while in the column is greater than or equal on the Style and design Torque calculated in Step three.
Refer to the highest RPM worth of your coupling dimension to ensure the application specifications are met. If your maximum RPM worth is significantly less than the application requirement, S-Flex couplings aren’t encouraged to the application.
Note:
If Nominal Torque is significantly less than 1/4 with the coupling’s nominalrated torque, misalignment capacities are diminished by 1/2. When torque value is located, refer to the corresponding coupling dimension within the 1st column with the S-Flex Nominal Rated Torque Information Chart three .
Step seven: Evaluate the application driver/driven shaft sizes to your greatest bore dimension out there to the coupling chosen. If coupling max bore is not really large ample for that shaft diameter, pick the next greatest coupling which will accommodate the driver/driven shaft diameters.
Stage eight: Making use of the Item Variety tables, locate the proper Keyway and Bore size expected and find the amount.
