摘　　要：应用微分几何知识,以曲面上的短程曲率为基础,将非圆锥齿轮副的球面节曲线在平面上展开,并结合平面当量节曲线的有关知识,提出了当量齿轮的齿形计算方法,成功地将非圆锥齿轮的设计转化为平面齿轮设计,实现了非圆锥齿轮的计算机辅助设计。Bases on differential geometry and the short distance curvature of the pitch curve on spherical surface,the pitch curve of spherical surface is expanded on plane.And the numerical calculation method of the tooth curve of equivalent gear according to equivalent pitch curve is put forward.Finally,the design of noncircular bevel gear is transform to design on plane,and designing of noncircular bevel gear is realized successfully.

关 键 词：非圆锥齿轮 传动比 节曲线 辅助设计
