An improved gear burnisher for removing minor gear tooth defects by burnishing is provided by rotating the work gear to be burnished in mesh with three different burnihing gears, at least one of which is powered. The improvement consists of burnishing the work gear with one burnishing gear that has a low operating pressure angle, another that has a high operating pressure angle and a third burnishing gear that has an intermediate operating pressure angle. The third also preferably has a generated pressure angle that is 0.5 degrees or more greater than the generated pressure angle of the work gear to provide a concentrated radial pressure sliding load at the tips of the teeth of the work gear. |
