Ring And Pinion Wear Pattern Chart
Toe contact pattern is concentrated off the toe end of the drive gear tooth.
Ring and pinion wear pattern chart. Use gear marking compound to paint all of the ring gear teeth. For more in depth information about ring and pinion gear patterns and how. Ring gear and pinion tooth pattern interpretation the final pinion position will be verified by using the gear contact pattern method described as follows. This pattern indicates excessive pinion depth.
Ring and pinion gear pattern is one of the most valuable tools for determining if a differential is properly set up. After the gears are installed using a pinion depth setting tool you should always check the wear pattern using a marking compound. You should see the wear pattern closer to the toe of the tooth with most gear sets. When the pinion is too far in towards the ring gear the pattern is low toward the base of the gear teeth.
The images below illustrate both acceptable and unacceptable ring and pinion gear patterns. 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. Ring and pinion gear pattern interpretation adjustment. The heel of the gear tooth is the portion of.
Teeth on the gear set are excessively worn chipped or broken. Move the ring gear closer to the pinion decrease backlash while maintaining minimum backlash. Load the ring gear and run a full contact pattern check. Proper ring gear to pinion gear contact pattern is critical for quiet and trouble free gear set operation.
