Ring and pinion tooth contact pattern.
Ring and pinion contact pattern.
Moving the ring gear toward the pinion removes the backlash and moves the contact pattern closer to the toe.
The differential ring gear backlash is correct.
Toe contact pattern is concentrated off the toe end of the drive gear tooth.
The ring gear is too far in toward the pinion.
The images below illustrate both acceptable and unacceptable ring and pinion gear patterns.
Move the ring gear away from the pinion increase backlash while maintaining minimum backlash.
A contact pattern that is worn in the center of the differential ring gear tooth toward the heel.
Begin by setting proper pinion bearing preload total turning preload and ring gear backlash.
The ring and pinion tooth contact pattern is used to double check ring and pinion adjustment.
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.
This pattern indicates excessive.
For more in depth information about ring and pinion gear patterns and how.
A thicker drive pinion shim is needed.
The low contact pattern indicates that the drive pinion is installed too deep into the carrier.
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 gear pattern interpretation adjustment.
Tooth contact pattern shown on the drive side of the gear teeth.
Use gear marking compound to paint all of the ring gear.
