  • Spiral shear gear burnishing dies
    Patent number: 6678929
    Abstract: A burnishing gear or burnishing die has a plurality of spiral gashes formed within each one of the burnishing gear teeth at a predetermined angle with respect to a transverse plane so as to define shearing edges along side involute portions of the burnishing gear teeth. The shearing edges enable enhanced finishing or burnishing operations to be performed upon workpiece gears in order to effectively remove positive imperfections, irregularities, nicks, or the like from the workpiece gear teeth so as to finish the workpiece gear in accordance with desired tolerances. The burnishing gear may be incorporated within burnishing gear systems utilizing burnishing gears characterized by different operating pressure angles as well as within burnishing gear systems that have mechanisms for reciprocating the workpiece gear during a gear burnishing operation.
