歯当たりを考慮した等高歯ハイポイドギヤの歯切り法に関する研究 : 第3報,歯当たり楕円と歯切り試験(機械要素,潤滑,工作,生産管理など)

The purpose of this study is to develop a gear-cutting method of hypoid gears to achieve a good tooth bearing and good performance for practical use. In the first report, the authors proposed a new cutting method of parallel depth hypoid gears which mesh with each other at one point at a constant angular velocity ratio, and precisely stated the theory for the gear-cutting method. In the second report, the theory of the trace of the point contact mark is shown precisely. 0ne of the features of this method is that the designer can control the trace of the point contact mark on the tooth surface as desired. In this report, the theory of the ellipse of tooth bearing is shown precisely. In order to confirm the validity of the method, some hypoid gears were designed and manufactured, and ellipse of tooth bearing on red lead corresponded to those of the theory.
