Moving the ring gear away from the pinion increases backlash and causes the pattern to move out toward the heel of the ring gear.
Ring and pinion wear pattern chart.
When the pinion is too far in towards the ring gear the pattern is low toward the base of the gear teeth.
Ring gear and pinion tooth pattern interpretation the final pinion position will be verified by using the gear contact pattern method described as follows.
Toe contact pattern is concentrated off the toe end of the drive gear tooth.
Use gear marking compound to paint all of the ring gear teeth.
Begin by setting proper pinion bearing preload total turning preload and ring gear backlash.
For more in depth information about ring and pinion gear patterns and how.
Load the ring gear and run a full contact pattern check.
Move the ring gear closer to the pinion decrease backlash while maintaining minimum backlash.
The heel of the gear tooth is the portion of.
The images below illustrate both acceptable and unacceptable ring and pinion gear patterns.
You should see the wear pattern closer to the toe of the tooth with most gear sets.
Proper ring gear to pinion gear contact pattern is critical for quiet and trouble free gear set operation.
Ring and pinion gear pattern interpretation adjustment.
Ring and pinion gear pattern is one of the most valuable tools for determining if a differential is properly set up.
This pattern indicates excessive pinion depth.
Ring gear tooth profile face hobbing face milling the toe of the gear is the portion of the tooth surface at the end towards the center.
