Ring And Pinion Wear Pattern Chart

Ring gear and pinion tooth pattern interpretation the final pinion position will be verified by using the gear contact pattern method described as follows.

Ring and pinion wear pattern chart.

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. The images below illustrate both acceptable and unacceptable ring and pinion gear patterns. Toe contact pattern is concentrated off the toe end of the drive gear tooth.

Load the ring gear and run a full contact pattern check. Begin by setting proper pinion bearing preload total turning preload and ring gear backlash. 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.

After the gears are installed using a pinion depth setting tool you should always check the wear pattern using a marking compound. Teeth on the gear set are excessively worn chipped or broken. 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. The heel of the gear tooth is the portion of.

The ring gear is too far in toward the pinion. Moving the ring gear away from the pinion increases backlash and causes the pattern to move out toward the heel of the ring gear. For more in depth information about ring and pinion gear patterns and how. Move the ring gear closer to the pinion decrease backlash while maintaining minimum backlash.
