Jaw Type Coupling Variety Approach
The variety approach for identifying the correct jaw coupling size and elastomer needs using the charts proven around the following pages. You can find 3 parts for being selected, two hubs and a single elastomer. When the shaft dimension with the driver and driven on the application are of your very same diameter, the hubs chosen are going to be the same. When shaft diameters vary, hubs picked will differ accordingly.
Info important before a coupling could be picked:
HP (or KW) and RPM or Torque of driver
Shaft sizes of driver and driven gear and corresponding keyways
Application description
Environmental problems (i.e. intense temperature, corrosive situations, room limitations)
Techniques In Deciding on A Jaw Coupling
Stage one: Identify the Nominal Torque of your application through the use of the following formula:
Nominal Torque = in-lb = (HP x 63025)/RPM
Nm = (KW x 9550)/RPM
Step 2: Making use of the Application Services Components Chart 1 select the services issue which ideal corresponds to your application.
Stage three: Calculate the Design and style Torque of one’s application by multiplying the Nominal Torque calculated in Step one through the Application Support Component determined in Phase two.
Layout Torque = Nominal Torque x Application Services Element
Stage four: Applying the Spider Performance Information Chart 2, choose the elastomer materials which greatest corresponds to your application.
Phase five: Utilizing the Jaw Nominal Rated Torque Chart three , find the appropriate elastomer material column for that elastomer selected in Phase four.
Scan down this column to the very first entry in which the Torque Worth while in the ideal column is better than or equal on the Style Torque calculated in Phase three.
The moment this value is located, refer on the corresponding coupling size while in the very first column from the Jaw Nominal Rated Torque Chart three .
Refer to your maximum RPM worth for this elastomer torque capability to make sure that the application prerequisites are met. If your requirement just isn’t satisfied at this point, one more style of coupling could be required for your application. Please seek the advice of Lovejoy engineering for assistance.
Stage six: Review the application driver/driven shaft sizes to the highest bore dimension out there around the coupling selected. If coupling bore size is not massive ample for that shaft diameter, choose the next largest coupling that may accommodate the driver/driven shaft diameters.
Step 7: Making use of the UPC quantity selection table , locate the ideal Bore and Keyway sizes demanded and locate the amount.
