Defines Ring (crown)/Drive shaft pinion velocity dependant meshing efficiency as a function of  .

The columns are:

[     (( )     ( )]

First column is angular velocity of the input driveshaft ()

Five options are available:

Entered value is taken as the constant efficiency for forward and backward cases

( ) = =

First entered value is taken as the constant efficiency for forward case and the second for backward cases

( ) =( ) =

First column is ignored and the second and third values are taken as constant efficiencies for forward and backward cases, respectively.

Second column is forward and backward efficiency

( ) = ( ) = ( )

Second column is forward efficiency

 ( )

Third column is backward efficiency

( )
