S-Flex Coupling Variety Course of action
The choice system for figuring out the appropriate S-Flex coupling requires using the charts proven within the following pages. There are actually 3 components to be picked, two flanges and 1 sleeve.
Information vital prior to a coupling could be selected:
HP and RPM of Driver or running torque
Shaft dimension of Driver and Driven tools and corresponding keyways
Application or equipment description
Environmental problems (i.e. excessive temperature, corrosive conditions, room limitations)
Steps In Deciding on An S-Flex Coupling
Phase 1: Determine the Nominal Torque in in-lb of your application through the use of the following formula:
Nominal Torque = (HP x 63025)/RPM
Step 2: Working with the Application Service Element Chart one pick the support component which very best corresponds for your application.
Stage three: Determine the Style and design Torque of one’s application by multiplying the Nominal Torque calculated in Phase 1 from the Application Support Issue established in Step 2.
Style Torque = Nominal Torque x Application Service Element
Step four: Using the Sleeve Functionality Information Chart two choose the sleeve material which greatest corresponds to your application.
Phase five: Applying the S-Flex Nominal Rated Torque Chart three locate the suitable sleeve materials column for the sleeve selected in Stage four.
Step 6: Scan down this column to the to start with entry in which the Torque Worth from the column is higher than or equal to the Style Torque calculated in Step 3.
Refer on the maximum RPM value from the coupling dimension to make certain the application needs are met. Should the highest RPM worth is significantly less than the application requirement, S-Flex couplings are usually not encouraged for that application.
Note:
If Nominal Torque is less than 1/4 from the coupling’s nominalrated torque, misalignment capacities are diminished by 1/2. The moment torque value is found, refer to your corresponding coupling size during the very first column on the S-Flex Nominal Rated Torque Information Chart three .
Phase 7: Evaluate the application driver/driven shaft sizes for the maximum bore size accessible about the coupling chosen. If coupling max bore will not be massive enough for your shaft diameter, select the subsequent biggest coupling that may accommodate the driver/driven shaft diameters.
Phase eight: Employing the Item Assortment tables, come across the proper Keyway and Bore dimension needed and locate the amount.
