Research of the Design and Roll Forming Experiment of Equal Helical Angle Spherical Involute Spiral Bevel gear

提出弧齿锥齿轮一种新的加工方法——滚轧加工。为实现该工艺,提出了采用等螺旋角球面渐开线弧齿锥齿轮齿形并给出了理论推导公式,推导了滚轧用齿坯的计算公式,给出了滚轧工具轮设计原则。通过自制的弧齿锥齿轮滚轧加工设备进行了滚轧实验,验证了该工艺的可行性。

A new method of manufacturing spiral bevel gear--roll forming process is proposed. In order to realize the process, the spherical involute spiral bevel gear with equal helix angle is proposed and the theoretical formula is derived. The computing formula of the gear blank for rolling process is given. The guideline of gear rolling tools design is presented. The roll experiment by using the self de- veloped roll equipment is carried out, the feasibility of roll forming process is verified.
