Method of manufacturing straight bevel gear with continuous indexing

摘要

The manufacturing method uses a numerically-controlled machine tool with a planar cutting head, with differing path radii (rwi,rwa) for an inner blade and an outer blade for cutting opposing right and left flanks of a tooth gap, providing a cog tooth with a tapering tooth height and a hypocycloid tooth line. The blade head has inner baldes and outer blades arranged uniformly in groups on the planar side, the following angle between inner and outer blades of a group being less than half the blade group angle.
