The toe of the gear is the portion of the tooth surface at the end towards the center. Web paint gear teeth with compound in several spots and rotate ring gear several revolutions. The top land of a gear tooth is the surface of the top of the tooth. Web ring gear and pinion tooth pattern interpretation. The coast pattern should be centered on the tooth, but may be slightly toward the toe.
The tooth contact is readily affected by changes in pinion axial position. Move the pinion gear closer to the ring gear. The heel of the gear tooth is the portion of the tooth surface at the outer end. Tooth contact pattern shown on the drive side of the gear teeth. Reading contact patterns can be daunting when looking at the average gear installation guide.
The contact pattern on the drive side (convex) of the tooth is mostly towards the toe. The final pinion position will be verified by using the gear contact pattern method described as follows: Web tooth contact patterns are a function of the relative positions of the ring gear and the pinion. Web paint gear teeth with compound in several spots and rotate ring gear several revolutions. An improper pattern will require a relocation of either or both.

Web the drive pattern should be centered on the tooth. Web possible cause #2: This leads us to the following rule for ratios of approximately 2.5:1 and higher: Use shims to move the pinion closer to the ring gear to move the drive pattern deeper on the tooth (flank contact) and slightly toward the toe. Web paint gear teeth with compound in several spots and rotate ring gear several revolutions. The heel of the gear tooth is the portion of the tooth surface at the outer end. Pinion mounting distance (pmd) adjustment. Always adjust pinion position first, if necessary, then the ring gear position. An improper pattern will require a relocation of either or both. Every gear has a characteristic pattern. There should be some clearance between the pattern and the top of the tooth. Use shims to move the ring gear closer to the pinion gear to decrease backlash. Web toe contact pattern is concentrated off the toe end of the drive gear tooth. Move the pinion gear closer to the ring gear. A contact pattern that is worn in the center of the differential ring gear tooth toward the heel.
The Contact Pattern On The Drive Side (Convex) Of The Tooth Is Mostly Towards The Toe.
The measuring calliper will identify the number of teeth in the crown and pinion, enabling a comparison against the specified design to ensure accuracy. Web paint gear teeth with compound in several spots and rotate ring gear several revolutions. Use shims to move the ring gear farther from the pinion gear to increase backlash. Web a high, thin contact pattern that is worn toward the toe.
Web Toe Contact Pattern Is Concentrated Off The Toe End Of The Drive Gear Tooth.
The final pinion position will be verified by using the gear contact pattern method described as follows: Every gear has a characteristic pattern. Use shims to move the ring gear farther from the pinion gear to increase backlash. Increase the differential ring gear backlash.
Check For Worn Bearings And Replace As Necessary.
Web tooth contact patterns are a function of the relative positions of the ring gear and the pinion. The top land of a gear tooth is the surface of the top of the tooth. The gear manufacturer will calculate in advance the amount of lead modification for each gear and the predicted tooth contact pattern. Web ring gear and pinion tooth pattern interpretation.
