S-Flex Assortment

Process
S-Flex Coupling Variety Course of action
The selection system for figuring out the appropriate S-Flex coupling needs making use of the charts proven on the following pages. You will find 3 components to get selected, two flanges and a single sleeve.
Information needed in advance of a coupling is often selected:
HP and RPM of Driver or working torque
Shaft size of Driver and Driven products and corresponding keyways
Application or equipment description
Environmental circumstances (i.e. extreme temperature, corrosive situations, room limitations)
Ways In Selecting An S-Flex Coupling
Step 1: Ascertain the Nominal Torque in in-lb of the application by using the following formula:
Nominal Torque = (HP x 63025)/RPM
Step two: Using the Application Services Element Chart 1 decide on the support component which most effective corresponds for your application.
Stage three: Determine the Style Torque of the application by multiplying the Nominal Torque calculated in Phase 1 through the Application Support Issue determined in Phase 2.
Style Torque = Nominal Torque x Application Support Issue
Step four: Working with the Sleeve Performance Data Chart two decide on the sleeve materials which finest corresponds to your application.
Stage five: Using the S-Flex Nominal Rated Torque Chart three locate the acceptable sleeve materials column for the sleeve picked in Phase four.
Step 6: Scan down this column for the initial entry in which the Torque Worth inside the column is better than or equal to the Design Torque calculated in Stage 3.
Refer on the maximum RPM worth from the coupling dimension to make sure that the application necessities are met. Should the highest RPM value is less than the application requirement, S-Flex couplings aren’t proposed for that application.
Note:
If Nominal Torque is significantly less than 1/4 on the coupling’s nominalrated torque, misalignment capacities are reduced by 1/2. After torque value is located, refer towards the corresponding coupling size while in the first column with the S-Flex Nominal Rated Torque Data Chart 3 .
Step 7: Evaluate the application driver/driven shaft sizes to the optimum bore dimension accessible around the coupling selected. If coupling max bore will not be big adequate for that shaft diameter, select the subsequent largest coupling that should accommodate the driver/driven shaft diameters.
Step 8: Utilizing the Item Selection tables, find the proper Keyway and Bore size demanded and locate the amount.
