Ring And Pinion Gear Pattern Chart

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 chart.

Move the ring gear away from the pinion increase backlash while maintaining minimum backlash. Load the ring gear and run a full contact pattern check. Ring gear and pinion tooth pattern interpretation the final pinion position will be verified by using the gear contact pattern method described as follows. Toe contact pattern is concentrated off the toe end of the drive gear tooth.

Use gear marking compound to paint all of the ring gear teeth. This pattern indicates excessive pinion depth. When setting the pinion position many of the service manuals required a final pinion position check by using gauges that verified the dimension from the center line of the differential carrier center line of ring gear to the face of the pinion button. Ring and pinion gear pattern is one of the most valuable tools for determining if a differential is properly set up.

When the pinion is too far in towards the ring gear the pattern is low toward the base of the gear teeth. Proper ring gear to pinion gear contact pattern is critical for quiet and trouble free gear set operation. Move the ring gear closer to the pinion decrease backlash while maintaining minimum backlash. 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. For more in depth information about ring and pinion gear patterns and how. Begin by setting proper pinion bearing preload total turning preload and ring gear backlash. The ring gear is too far in toward the pinion.
