A structurally tuned, vibration-based component checking system for detecting anomalies in a component of an assembly prior to the component being installed in the assembly is provided. The component checking system operates the component being tested at a speed that is different from the speed at which the component operates during normal use in the assembly, and also under a different load. To compensate for this difference in speed and load, the component checking system is structurally tuned such that a relationship exists between the modal frequencies and speed of operation of the component checking system and the modal frequencies and speed of operation of the assembly.

Structurally tuned vibration based component checking system and method

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.
