Ring And Pinion Gear Pattern

Move the ring gear closer to the pinion decrease backlash while maintaining minimum backlash.

Ring and pinion gear pattern.

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

Proper ring gear to pinion gear contact pattern is critical for quiet and trouble free gear set operation. Move the ring gear away from the pinion increase backlash while maintaining minimum backlash. Ring and pinion gear pattern is one of the most valuable tools for determining if a differential is properly set up. Ring and pinion gear pattern interpretation adjustment.

This pattern indicates excessive pinion depth. The ring gear is too far in toward the pinion. 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 setting up a ring pinion there are four critical settings that need to be correct in order to get proper setup and good gear life.

Ring gear and pinion tooth pattern interpretation the final pinion position will be verified by using the gear contact pattern method described as follows. 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. Load the ring gear and run a full contact pattern check.
