Jaw Coupling Variety Process

Jaw Form Coupling Choice Method
The assortment process for identifying the correct jaw coupling size and elastomer needs utilizing the charts shown on the following pages. You will find three parts to be selected, two hubs and a single elastomer. When the shaft size from the driver and driven with the application are from the similar diameter, the hubs picked will likely be exactly the same. When shaft diameters vary, hubs chosen will differ accordingly.
Data important just before a coupling could be selected:
HP (or KW) and RPM or Torque of driver
Shaft sizes of driver and driven equipment and corresponding keyways
Application description
Environmental ailments (i.e. excessive temperature, corrosive conditions, area limitations)
Steps In Deciding on A Jaw Coupling
Step 1: Establish the Nominal Torque of one’s application by utilizing the following formula:
Nominal Torque = in-lb = (HP x 63025)/RPM
Nm = (KW x 9550)/RPM
Stage two: Applying the Application Support Things Chart one decide on the service element which greatest corresponds for your application.
Phase 3: Determine the Design Torque of the application by multiplying the Nominal Torque calculated in Step one through the Application Service Aspect determined in Phase two.
Layout Torque = Nominal Torque x Application Services Issue
Stage 4: Making use of the Spider Performance Information Chart 2, choose the elastomer materials which ideal corresponds for your application.
Stage 5: Employing the Jaw Nominal Rated Torque Chart 3 , find the acceptable elastomer materials column for that elastomer picked in Stage four.
Scan down this column to the initially entry the place the Torque Value within the acceptable column is greater than or equal towards the Layout Torque calculated in Step three.
As soon as this value is found, refer on the corresponding coupling dimension while in the to start with column of your Jaw Nominal Rated Torque Chart 3 .
Refer on the maximum RPM value for this elastomer torque capability to make sure that the application demands are met. If your requirement isn’t happy at this time, one more type of coupling could be expected for the application. Please seek advice from Lovejoy engineering for help.
Step six: Review the application driver/driven shaft sizes to your greatest bore size readily available about the coupling picked. If coupling bore size is just not massive ample for that shaft diameter, select the subsequent largest coupling that may accommodate the driver/driven shaft diameters.
Stage 7: Working with the UPC variety choice table , come across the ideal Bore and Keyway sizes needed and locate the variety.
