View Full Version : C-C distance gears. Pressure Angle

For the gear folks...

Does the center to center mounting distance change if the pressure angle changes? Teeth count are the same; DP is the same. Nothing differs but the pressure angle. i.e. from 14.5 to 20 degrees. Both gears are exchanged.

Scenario: working with a machine with two gears already spaced by the original machine design. The 14.5 degree gears are more costly, but 20 degree PA gears are also available. The original gears are 14.5 PA. I am considering replacing with 20 PA gears.

The center distance will not change.
