S-Flex Coupling Variety Process
The selection course of action for figuring out the appropriate S-Flex coupling involves employing the charts proven on the following pages. You will discover 3 elements to become picked, two flanges and one sleeve.
Details vital prior to a coupling is usually chosen:
HP and RPM of Driver or working torque
Shaft dimension of Driver and Driven tools and corresponding keyways
Application or tools description
Environmental problems (i.e. excessive temperature, corrosive ailments, space limitations)
Ways In Selecting An S-Flex Coupling
Step 1: Decide the Nominal Torque in in-lb of the application through the use of the following formula:
Nominal Torque = (HP x 63025)/RPM
Step 2: Making use of the Application Support Element Chart 1 choose the support factor which greatest corresponds for your application.
Stage 3: Determine the Style and design Torque of the application by multiplying the Nominal Torque calculated in Phase one from the Application Support Aspect established in Stage two.
Style and design Torque = Nominal Torque x Application Support Component
Step four: Making use of the Sleeve Performance Data Chart two select the sleeve material which most effective corresponds to your application.
Step five: Applying the S-Flex Nominal Rated Torque Chart three locate the appropriate sleeve material column to the sleeve picked in Stage four.
Stage six: Scan down this column towards the first entry wherever the Torque Worth within the column is greater than or equal for the Style and design Torque calculated in Stage three.
Refer for the highest RPM worth of the coupling size to make certain the application prerequisites are met. If your optimum RPM worth is less than the application necessity, S-Flex couplings will not be advised for the application.
Note:
If Nominal Torque is less than 1/4 from the coupling’s nominalrated torque, misalignment capacities are reduced by 1/2. As soon as torque value is found, refer to the corresponding coupling dimension during the to start with column of the S-Flex Nominal Rated Torque Data Chart 3 .
Step seven: Review the application driver/driven shaft sizes on the optimum bore size available about the coupling selected. If coupling max bore isn’t huge adequate for the shaft diameter, choose the next greatest coupling which will accommodate the driver/driven shaft diameters.
Phase eight: Utilizing the Item Assortment tables, discover the ideal Keyway and Bore size essential and locate the quantity.
