Ring And Pinion Contact Pattern

A thicker drive pinion shim is needed.

Ring and pinion contact pattern.

Ring gear contact pattern interpretation of face hobbed uniform tooth depth gear teeth proper ring gear to pinion gear contact pattern is critical for quiet and trouble free gear set operation. Ring and pinion gear pattern is one of the most valuable tools for determining if a differential is properly set up. A contact pattern that is worn in the center of the differential ring gear tooth toward the heel. Ring and pinion tooth contact pattern.

This pattern indicates excessive. Use gear marking compound to paint all of the ring gear. Tooth contact pattern shown on the drive side of the gear teeth. Moving the ring gear away from the pinion increases backlash and causes the pattern to move out toward the heel of the ring gear.

For more in depth information about ring and pinion gear patterns and how. The images below illustrate both acceptable and unacceptable ring and pinion gear patterns. Ring and pinion gear pattern interpretation adjustment. This is the opposite of c.

The low contact pattern indicates that the drive pinion is installed too deep into the carrier. Begin by setting proper pinion bearing preload total turning preload and ring gear backlash. Move the ring gear away from the pinion increase backlash while maintaining minimum backlash. The ring gear is too far in toward the pinion.

Moving the ring gear toward the pinion removes the backlash and moves the contact pattern closer to the toe. The ring and pinion tooth contact pattern is used to double check ring and pinion adjustment.
