Ring And Pinion Gear Pattern Chart
Ring and pinion gear pattern interpretation adjustment.
Ring and pinion gear pattern chart. Move the ring gear closer to the pinion decrease backlash while maintaining minimum backlash. Move the ring gear away from the pinion increase backlash while maintaining minimum backlash. The ring gear is too far in toward the pinion. This pattern indicates excessive pinion depth.
Begin by setting proper pinion bearing preload total turning preload and ring gear backlash. The heel of the gear tooth is the portion of. Ring and pinion gear pattern is one of the most valuable tools for determining if a differential is properly set up. Toe contact pattern is concentrated off the toe end of the drive gear tooth.
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 images below illustrate both acceptable and unacceptable ring and pinion gear patterns. 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. Proper ring gear to pinion gear contact pattern is critical for quiet and trouble free gear set operation.
Ring gear and pinion tooth pattern interpretation. Load the ring gear and run a full contact pattern check. 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.
