Abstract
It is the research on the face gear expected as a substitution of the bevel gear and hypoid gear. First, the geometrical design method of the face gear was introduced, and how to decide an effective engagement area under the design parameter was explained. In continuing, how to avoid the influence of machining and assembling error on tooth bearing of the face gear was shown. So, in this paper, on the face gear with modified tooth flank by some methods, for example, the conventional method which modifies tooth profile of pinion, the influence of machining and assembling error on tooth bearing was investigated by tooth contact analysis (T. C. A.). And the new method which modifies gear tooth surface was proposed on condition that the hardened gear-teeth finishing process could be carried out by the general-purpose Multi-Tasking machine. A numerical example was presented based on the proposed method.
