Abstract:

Since there is not appropriative grinding machines and technology for the manufacture of new micro-segment gears, a method is proposed for manufacturing the high quality micro-segment gears by using present processing machines and testing equipments with considering the characteristics of the new gears. In which, an equation of the grinding surface of the micro-segment gears is derived, a set of grinding technology is established, and a testing method of the new tooth profiles is proposed. After manufacturing the micro-segment gears, the error of the tooth profiles, the mechanical efficiency and vibration spectrum of the new gears and corresponding involute gears are tested. The analysis results illustrate that the new gears have higher mechanical efficiency and better transmission stability than the involute gears.
