Abstract

Gear burnishing system having burnishing gear positions arranged around a subject gear at its center, a burnishing gear is formed as a scraper gear retained on a shaft rotationally by a keyway formed in an inner bore of the scraper gear which is wider by a predefined gap than a corresponding key formed on the shaft such that the scraper gear can move angularly by a small amount for maximum contact on the subject gear. In a preferred embodiment, a number of scraper gears are arranged in a stack on the shaft. Both ends of each scraper gear are beveled along the peripheral edges to cause each tooth to be raked and to create knife blades and serve to trap debris. Each tooth is formed with equal blade angles and a recess with compound angles for debris entrapment. The scraper gears can be mounted with bearings for limited gimbal movement.
