Ring And Pinion Contact Pattern

A contact pattern that is worn in the center of the differential ring gear tooth toward the heel.

Ring and pinion contact pattern. This pattern indicates excessive. A thicker drive pinion shim is needed. The images below illustrate both acceptable and unacceptable ring and pinion gear patterns. Moving the ring gear away from the pinion increases backlash and causes the pattern to move out toward the heel of the ring gear.

The differential ring gear backlash is correct. This is the opposite of c. Moving the ring gear toward the pinion removes the backlash and moves the contact pattern closer to the toe. For more in depth information about ring and pinion gear patterns and how.

The ring gear is too far in toward the pinion. Toe contact pattern is concentrated off the toe end of the drive gear tooth. 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.

The ring and pinion tooth contact pattern is used to double check ring and pinion adjustment. The low contact pattern indicates that the drive pinion is installed too deep into the carrier. Move the ring gear away from the pinion increase backlash while maintaining minimum backlash. Begin by setting proper pinion bearing preload total turning preload and ring gear backlash.

Tooth contact pattern shown on the drive side of the gear teeth. 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.
