Ring And Pinion Contact Pattern

Toe contact pattern is concentrated off the toe end of the drive gear tooth.

Ring and pinion contact pattern.

Moving the ring gear away from the pinion increases backlash and causes the pattern to move out toward the heel of the ring gear. This is the opposite of c. A contact pattern that is worn in the center of the differential ring gear tooth toward the heel. The low contact pattern indicates that the drive pinion is installed too deep into the carrier.

Ring and pinion tooth contact pattern. The differential ring gear backlash is correct. Moving the ring gear toward the pinion removes the backlash and moves the contact pattern closer to the toe. 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. The images below illustrate both acceptable and unacceptable ring and pinion gear patterns. The ring gear is too far in toward the pinion. Ring and pinion gear pattern is one of the most valuable tools for determining if a differential is properly set up.

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 interpretation adjustment. A thicker drive pinion shim is needed. Move the ring gear away from the pinion increase backlash while maintaining minimum backlash.

To check the accuracy of your adjustments coat the ring gear teeth with a thin coat of red lead white grease hydrated ferric oxide yellow oxide or iron or prussian blue. The ring and pinion tooth contact pattern is used to double check ring and pinion adjustment.
