Ring And Pinion Wear Pattern

Ring and pinion gear pattern interpretation adjustment.

Ring and pinion wear pattern.

Load the ring gear and run a full contact pattern check. The ring gear is too far in toward the pinion. 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. Ring and pinion gear pattern is one of the most valuable tools for determining if a differential is properly set up.

Use gear marking compound to paint all of the ring gear teeth. The heel of the gear tooth is the portion of. Low contact pattern is concentrated in the root of the drive gear tooth. The images below illustrate both acceptable and unacceptable ring and pinion gear patterns.

This pattern indicates excessive pinion depth. For more in depth information about ring and pinion gear patterns and how. Ring gear and pinion tooth pattern interpretation the final pinion position will be verified by using the gear contact pattern method described as follows. Moving the ring gear away from the pinion increases backlash and causes the pattern to move out toward the heel of the ring gear.

Move the pinion out away from the differential carrier subtract pinion shim. Proper ring gear to pinion gear contact pattern is critical for quiet and trouble free gear set operation.
