Abstract
A method of manufacturing bevel and hypoid gear pairs according to an imaginary mating gear cutting process. The tooth spaces are cut by means of a face-mill cutter head rotating about an axis of rotation. In order to overcome heretofore prevailing limitations on the gear diameter, cone angle and shaft angle of gear pairs, either the gear or the cutter head performs an arcuate generating movement about a generating axis in order to produce one of the gears, whereby a machining axis is adjusted relative to the generating axis in accordance with the position of the axes of both gears of the gear pair. In one advantageous embodiment, the same machining axis adjustment is also employed for fabricating the mating, non-generated gear.
