System
S-Flex Coupling Assortment Course of action
The selection system for identifying the appropriate S-Flex coupling demands applying the charts proven about the following pages. You will find 3 components for being picked, two flanges and 1 sleeve.
Facts needed just before a coupling can be picked:
HP and RPM of Driver or working torque
Shaft dimension of Driver and Driven equipment and corresponding keyways
Application or products description
Environmental situations (i.e. excessive temperature, corrosive circumstances, area limitations)
Measures In Picking 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
Phase two: Utilizing the Application Services Component Chart 1 pick the services aspect which most effective corresponds to your application.
Step 3: Calculate the Style and design Torque of the application by multiplying the Nominal Torque calculated in Phase 1 through the Application Support Factor determined in Step two.
Design and style Torque = Nominal Torque x Application Support Element
Step four: Applying the Sleeve Overall performance Information Chart 2 choose the sleeve material which most effective corresponds to your application.
Phase five: Using the S-Flex Nominal Rated Torque Chart three find the appropriate sleeve materials column for the sleeve picked in Phase 4.
Phase 6: Scan down this column to your very first entry exactly where the Torque Worth in the column is higher than or equal for the Style Torque calculated in Stage three.
Refer towards the highest RPM value on the coupling size to guarantee the application demands are met. When the highest RPM worth is significantly less compared to the application requirement, S-Flex couplings usually are not advised for your application.
Note:
If Nominal Torque is much less than 1/4 of your coupling’s nominalrated torque, misalignment capacities are reduced by 1/2. Once torque worth is located, refer to the corresponding coupling size inside the very first column from the S-Flex Nominal Rated Torque Information Chart 3 .
Phase seven: Evaluate the application driver/driven shaft sizes towards the highest bore size obtainable about the coupling chosen. If coupling max bore isn’t huge ample for that shaft diameter, choose the following greatest coupling that can accommodate the driver/driven shaft diameters.
Phase 8: Applying the Item Selection tables, come across the suitable Keyway and Bore size needed and find the quantity.
