ABSTRACT:
At the gear manufacturing machine there are automatically fabricated longitudinally curved tooth gears, especially longitudinally curved tooth bevel and hypoid gears according to conventional stock-removal form or generating methods. In order to improve both the mechanical stability and kinematic stability, the gear manufacturing machine contains only so-to-speak "natural" gear manufacturing or cutting axes, and, in particular, does not contain any hypoid stock, however, a generating drum. With the method of operating such gear manufacturing machine it is possible to fabricate hypoid gears during the generating operation by performing an additional movement of the workpiece in the lengthwise direction of the tooth pitch cone.
