研究了弧齿锥齿轮和准双曲面齿轮的新切齿计算方法,开发了包含新切齿算法和旧切齿算法的相应程序模块的应用技术软件系统。该系统可完成SGM、SFM、SGT、SFT、HGM、HFM、HGT、HFT切齿法的齿坯几何参数、切齿调整参数、轮齿接触分析、磨齿调整参数和根切检验等计算。新切齿算法能指定大轮齿面上接触区中心的位置,该处的接触区长度,接触迹线的方向和轮副相对运动角加速度等参数。系统用户友好,易操作使用。 The calculation method of new incisor of spiral bevel gear and hypoid gear is studied. The application software system of corresponding program module including new incisor algorithm and old incisor algorithm is developed. The system can finish the tooth blank geometric parameters, gear cutting parameters, tooth contact analysis, grinding parameters and root cut test of SGM, SFM, SGT, SFT, HGM, HFM, HGT and HFT. The new incisor algorithm can specify parameters such as the position of the center of the contact area on the large gear tooth surface, the length of the contact area there, the direction of the contact trace, and the relative angular acceleration of the wheel set. System user-friendly, easy to use.
