S-Flex Coupling Selection Process
The variety system for determining the right S-Flex coupling requires applying the charts proven within the following pages. You can find 3 elements for being selected, two flanges and one sleeve.
Info vital before a coupling can be chosen:
HP and RPM of Driver or operating torque
Shaft dimension of Driver and Driven gear and corresponding keyways
Application or products description
Environmental circumstances (i.e. extreme temperature, corrosive ailments, area limitations)
Measures In Picking out An S-Flex Coupling
Stage 1: Ascertain the Nominal Torque in in-lb of the application by using the following formula:
Nominal Torque = (HP x 63025)/RPM
Stage 2: Using the Application Services Factor Chart one pick the service element which very best corresponds to your application.
Phase 3: Determine the Design and style Torque of the application by multiplying the Nominal Torque calculated in Phase 1 from the Application Service Component established in Step 2.
Layout Torque = Nominal Torque x Application Service Component
Step 4: Making use of the Sleeve Effectiveness Information Chart two decide on the sleeve material which very best corresponds to your application.
Stage five: Applying the S-Flex Nominal Rated Torque Chart three find the suitable sleeve material column to the sleeve selected in Stage 4.
Phase six: Scan down this column to your initially entry where the Torque Value inside the column is greater than or equal on the Layout Torque calculated in Step three.
Refer on the maximum RPM worth on the coupling dimension to make sure that the application prerequisites are met. If the optimum RPM worth is less compared to the application requirement, S-Flex couplings will not be recommended to the application.
Note:
If Nominal Torque is significantly less than 1/4 with the coupling’s nominalrated torque, misalignment capacities are reduced by 1/2. After torque value is found, refer to the corresponding coupling size in the very first column with the S-Flex Nominal Rated Torque Information Chart 3 .
Step 7: Assess the application driver/driven shaft sizes on the optimum bore size out there on the coupling chosen. If coupling max bore is just not huge ample for that shaft diameter, decide on the subsequent greatest coupling that could accommodate the driver/driven shaft diameters.
Phase eight: Utilizing the Item Assortment tables, come across the appropriate Keyway and Bore dimension demanded and find the number.
