Abstract
Precise micromodule small gears are necessary to realize high-strength low-noise compact geared motors. In the gear manufacturing process, burrs and nicks are generated at the edge or ridgeline of the work gear tooth and they get the gear accuracy worse. Therefore a removal method of burrs and nicks is important. However, it is difficult to remove them from small gears by using usual tools and usual processing devices because the tooth groove of small gears is narrow. In order to solve these problems, FRP gear-shaped tool and finishing device for small gears using oscillation have been developed in this research. Experiments are carried out and it is confirmed that the proposed method can remove burrs and nicks from small gears.
