S-Flex Coupling Variety System
The assortment system for determining the right S-Flex coupling involves working with the charts proven within the following pages. You will find 3 parts for being picked, two flanges and one sleeve.
Info vital just before a coupling might be chosen:
HP and RPM of Driver or operating torque
Shaft dimension of Driver and Driven gear and corresponding keyways
Application or gear description
Environmental problems (i.e. excessive temperature, corrosive situations, area limitations)
Techniques In Picking An S-Flex Coupling
Stage 1: Identify the Nominal Torque in in-lb of one’s application by using the following formula:
Nominal Torque = (HP x 63025)/RPM
Phase two: Making use of the Application Support Issue Chart 1 pick the support element which ideal corresponds to your application.
Step three: Calculate the Style Torque of the application by multiplying the Nominal Torque calculated in Step one by the Application Services Component established in Stage 2.
Layout Torque = Nominal Torque x Application Support Factor
Phase 4: Using the Sleeve Performance Data Chart two pick the sleeve material which best corresponds to your application.
Phase 5: Applying the S-Flex Nominal Rated Torque Chart 3 find the ideal sleeve material column to the sleeve selected in Phase four.
Phase six: Scan down this column to your 1st entry in which the Torque Worth within the column is better than or equal for the Layout Torque calculated in Phase three.
Refer on the maximum RPM worth in the coupling size to guarantee the application requirements are met. Should the greatest RPM value is less compared to the application necessity, S-Flex couplings will not be advised for that application.
Note:
If Nominal Torque is less than 1/4 on the coupling’s nominalrated torque, misalignment capacities are diminished by 1/2. When torque worth is found, refer on the corresponding coupling size during the to start with column with the S-Flex Nominal Rated Torque Data Chart 3 .
Stage seven: Evaluate the application driver/driven shaft sizes for the optimum bore dimension readily available over the coupling chosen. If coupling max bore just isn’t massive ample to the shaft diameter, choose the following greatest coupling which will accommodate the driver/driven shaft diameters.
Phase eight: Making use of the Item Assortment tables, find the appropriate Keyway and Bore size needed and find the variety.
