Process Method of Face-gear Drive with Spur Involute Pinion with the Shaping Machine

实现面齿轮加工是面齿轮传动研究的基础,利用齿轮插齿加工方法,对正交非偏置面齿轮插齿加工中过程包络面和理论齿廓的干涉进行研究,目的是为了验证这种加工方法的可行性。根据插齿加工的原理,建立了面齿轮插齿加工坐标系,给出了插刀理论齿廓方程,推导了面齿轮插齿加工理论齿廓方程和加工中过程包络面方程;分析了过程包络面和面齿轮插齿加工理论齿廓的位置关系,仿真计算结果表明面齿轮插齿加工不会引起过程包络面和插齿理论齿廓的干涉;最终,通过面齿轮插齿加工试验论证了上述结果的正确性。

In order to research face-gear drives, a face-gear drive with spur involute pinion is considered. The genera, tion of a face gear is based on application of a conventional shaping machine and an involute shaper. The functions of theoretic shaping surface and processing surface about the face gear are deduced. Computer programs are developed for simulation of these surfaces. In shaping time, mutual position of two surfaces, theoretic shaping surface and processing surface, is analyzed by simulation. In the end, the feasibility of the process method is concluded.
