Web five cut ring & pinion gears (face milled): Web in general, pattern movements can be summarized this way: When setting the pinion position, many of the service manuals required a final pinion position check by using guages that verified the dimension from the center line of the different carrier (center line of ring gear) to the face of the pinion (button). Web shows how varying pinion depth and back lash a few thousandths of an inch affect ring and pinion pattern. Web ring gear and pinion tooth contact pattern the toe of the gear tooth 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. This chart illustrates different patterns and adjustments.

A contact pattern closer to the gear face means the pinion is too far away from the ring gear.

Pinion Bearing Preload Usually Provides Enough Resistance For A Good Pattern, But Additional Resistance Can Be Added By Wrapping A Shop Towel Around The Yoke And Pulling The Two Ends Tight.

See manufacturer or the gearset for exact specifications and special instructions before attempting to adjust the ring and pinion.

This is done using gear marking compound and checking the gear tooth pattern. Web at.039 pinion shim, the contact pattern on the ring gear was favoring the root of the ring gear on the drive side.

To Check The Contact Pattern, Apply Marking Compound To The Ring Gear Teeth And Run The Gears Under Load.

Ring gears use a pilot bearing that Web shows how varying pinion depth and back lash a few thousandths of an inch affect ring and pinion pattern.

Web ring gear and pinion tooth contact pattern the toe of the gear tooth is the portion of the tooth surface at the end towards the center.

How Did The Pinion Move.

This video was created to give people a basic understanding of. Web proper contact patterns between ring gear and pinion gear teeth are important for quiet gear operation.
