Ring And Pinion Gear Pattern

The heel of the gear tooth is the portion of the.

Ring and pinion gear pattern. Ring and pinion gear pattern interpretation adjustment. 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. Proper ring gear to pinion gear contact pattern is critical for quiet and trouble free gear set operation.

Ring gear and pinion tooth pattern interpretation the final pinion position will be verified by using the gear contact pattern method described as follows. Use gear marking compound to paint all of the ring gear teeth. The images below illustrate both acceptable and unacceptable ring and pinion gear patterns. Pinion depth how close the pinion is to the ring gear backlash how close the ring gear is to the pinion pinion bearing preload how much bearing drag is on the pinion bearings and carrier.

When the pinion is too far in towards the ring gear the pattern is low toward the base of the gear teeth. This pattern indicates excessive pinion depth. 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.

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 is one of the most valuable tools for determining if a differential is properly set up. For more in depth information about ring and pinion gear patterns and how. Toe contact pattern is concentrated off the toe end of the drive gear tooth.
