摘要：The aim of this study is to define optimal tooth modifications, introduced by appropriately chosen head-cutter geometry and machine tool setting, to simultaneously minimize tooth contact pressure and angular displacement error of the driven gear （transmission error） of face-hobbed spiral bevel gears. As a result of these modifications, the gear pair becomes mismatched, and a point contact replaces the theoretical line contact. In the applied loaded tooth contact analysis it is assumed that the point contact under load is spreading over a surface along the whole or part of the ‘‘potential’’ contact line. A computer program was developed to implement the formulation provided above. By using this program the influence of tooth modifications introduced by the variation in machine tool settings and in head cutter data on load and pressure distributions, transmission errors, and fillet stresses is investigated and discussed. The correlation between the ease-off obtained by pinion tooth modifications and the corresponding tooth contact pressure distribution is investigated and the obtained results are presented.

摘要：本文提出了设计和制造轴向圆弧滚刀的一种方法。文章中的计算涉及到以下几个方面:确定滚刀的成形表面和切削刃;铲磨滚刀齿时所用的锥形、盘形或铅笔形砂轮的廓形;为提高滚刀的重磨精度而采用的最佳砂轮安装角;以及如何确定重磨后滚刀的刃形与所需要的刃形之间的偏差。把以上的计算编成程序,运用这些程序就可以得出滚刀的升角以及用于铲磨的盘形砂轮的直径对于砂轮安装的最佳角的影响。结论:当砂轮采用最佳角安装时,滚刀的重磨精度有了很大提高。
