Ring And Pinion Gear Pattern

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

Ring and pinion gear pattern.

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. 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. The ring gear is too far in toward the pinion. Begin by setting proper pinion bearing preload total turning preload and ring gear backlash.

Toe contact pattern is concentrated off the toe end of the drive gear tooth. Ring and pinion gear pattern interpretation adjustment. Move the ring gear away from the pinion increase backlash while maintaining minimum backlash. Proper ring gear to pinion gear contact pattern is critical for quiet and trouble free gear set operation.

Ring and pinion gear pattern is one of the most valuable tools for determining if a differential is properly set up. 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. This pattern indicates excessive pinion depth. For more in depth information about ring and pinion gear patterns and how.

When the pinion is too far in towards the ring gear the pattern is low toward the base of the gear teeth. Use gear marking compound to paint all of the ring gear teeth. 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 images below illustrate both acceptable and unacceptable ring and pinion gear patterns.
