METHOD OF AND MEANS FOR GRINDING PAIRS OF GEAR WHEELS AS SPIRAL OR CURVED TOOTHED BEVEL GEAR WHEELS

摘要

When grinding spiral bevel gears (1, 2) by the indexing method, in each case two tooth flanks at one of the bevel gears (2) can be machined on both sides of a tooth gap in one operation with a cup grinding wheel (5), the grinding flanks (51, 52) of which form an outer bevel ring. To achieve the object of grinding a satisfactorily meshing mating gear (1) in one operation, it is proposed to use a cup grinding wheel (7) to grind the mating gear (1), the grinding flanks (71, 72) of which cup grinding wheel (7) face one another and form an inner bevel ring. To generate width crowning, a cyclic additional movement of slight eccentricity can be imparted to the grinding wheels (5, 7). IMAGE
