A simple method of bevel gear cutting (1st report, The basic conception of the cutting method)

Abstract

In some cases of bevel gear services, the most important demands of them are the cost and the speed of the gear production. This paper proposes a new simplified cutting method. In the method, both the face-milling cutter and the bevel gear work rotate at a high speed and the cutter is fed only in the direction of the tooth depth. This cutting method gives the spiral bevel gears the tooth surfaces, which are ruled by the cutter edge and are eased off on the tip and the bottom of tooth profile, and which contact almost exactly along the tooth trace. The relation of the shape of the cutter edge and the tooth gap of the mating tooth surfaces is investigated theoretically. Plastic bevel gears are cut trially. With these trials, it was assured that the cutting method is available.
