Jaw Sort Coupling Assortment Method
The variety method for identifying the right jaw coupling dimension and elastomer calls for applying the charts proven over the following pages. There are three parts to get picked, two hubs and one elastomer. Once the shaft size of your driver and driven of the application are on the very same diameter, the hubs selected will probably be the same. When shaft diameters vary, hubs chosen will vary accordingly.
Data important just before a coupling might be picked:
HP (or KW) and RPM or Torque of driver
Shaft sizes of driver and driven products and corresponding keyways
Application description
Environmental problems (i.e. intense temperature, corrosive ailments, area limitations)
Methods In Picking A Jaw Coupling
Phase one: Determine the Nominal Torque of your application through the use of the next formula:
Nominal Torque = in-lb = (HP x 63025)/RPM
Nm = (KW x 9550)/RPM
Phase two: Employing the Application Support Factors Chart one pick the services element which most effective corresponds to your application.
Stage three: Calculate the Style and design Torque of one’s application by multiplying the Nominal Torque calculated in Phase one through the Application Services Element established in Phase 2.
Style and design Torque = Nominal Torque x Application Service Aspect
Step 4: Working with the Spider Functionality Data Chart 2, select the elastomer material which most effective corresponds to your application.
Step 5: Applying the Jaw Nominal Rated Torque Chart 3 , locate the acceptable elastomer material column for the elastomer picked in Phase four.
Scan down this column to the initially entry in which the Torque Worth within the ideal column is higher than or equal to your Style and design Torque calculated in Phase three.
As soon as this worth is located, refer to the corresponding coupling size during the initial column of the Jaw Nominal Rated Torque Chart three .
Refer to the optimum RPM value for this elastomer torque capability to guarantee the application needs are met. If the requirement will not be content at this time, a further form of coupling can be needed for the application. Please talk to Lovejoy engineering for support.
Step 6: Examine the application driver/driven shaft sizes to the optimum bore dimension offered to the coupling picked. If coupling bore size just isn’t massive adequate for that shaft diameter, decide on the following biggest coupling that will accommodate the driver/driven shaft diameters.
Stage seven: Working with the UPC quantity selection table , discover the suitable Bore and Keyway sizes needed and locate the number.
