A new 'Automatic Gear Selecting Machine' has been developed for automated selection of transaxle gears with improved capability of detecting nicks on the teeth flanks. This machine, developed on the basis of a double-flank gear rolling tester, is capable of instantly taking measurements of, and making pass/fail determination on, Measurement over balls, Runout, Nick and Tooth-to-Tooth Composite Error. The system also includes a cleaning stand and a flank burnishing equipment through which products under test pass before coming to the double-flank gear rolling tester, and also a selection bench that is controlled to make correct pass/fail judgment. Conventional way of gear selection was been using a gear speeder to detect nicks on transmission gear teeth. However, measurement over balls, runout and tooth-to-tooth composite error could not be measured by the gear speeder and skilled workers were always needed to operate the gear speeder. Introduction of automated system bases on the double-flank gear rolling tester still had a problem that gears having nicks were passed and those having fine dust or burrs, but not nicks, were often rejected. Solutions to this problem lead to the development of a new system described in this paper. The new 'Automatic Gear Selecting Machine' demonstrates selecting performance three to four times more efficient than the conventional machine detecting nicks on the gear teeth.
