Ring And Pinion Pattern Chart

When the pinion is too far in towards the ring gear the pattern is low toward the base of the gear teeth.

Ring and pinion pattern chart.

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. Begin by setting proper pinion bearing preload total turning preload and ring gear backlash. Ring gear and pinion tooth pattern interpretation the final pinion position will be verified by using the gear contact pattern method described as follows. The images below illustrate both acceptable and unacceptable ring and pinion gear patterns.

For more in depth information about ring and pinion gear patterns and how. 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. Moving the ring gear away from the pinion increases backlash and causes the pattern to move out toward the heel of the ring gear. Proper ring gear to pinion gear contact pattern is critical for quiet and trouble free gear set operation.

Low contact pattern is concentrated in the root of the drive gear tooth. Move the pinion deeper in towards the differential carrier add pinion shim. The heel of the gear tooth is the portion of. Ring gear and pinion tooth pattern interpretation.

The ring gear is too far in toward the pinion. Move the pinion out away from the differential carrier subtract pinion shim. Load the ring gear and run a full contact pattern check. This pattern indicates excessive pinion depth.
