摘　　要：以曲面上曲线的短程曲率为媒介,导出了球面节曲线伸展成平面当量节曲线的算法。以平面当量节曲线为基础,通过确定插齿刀的节圆沿平面当量节曲线做纯滚动时插齿刀上各点的运动轨迹,模拟了插齿加工包络出当量齿轮的齿形过程,将非圆锥齿轮的设计转化为平面齿轮的设计,简化了非圆锥齿轮的设计。Geodesic curvature of the pitch curve on spherical surface was introduced as a medium, through which the pitch curve on spherical surface can be changed into equivalent planar pitch curve by numerical computation method. On the basis of equivalent planar pitch, the tooth profile of the equivalent gear was gotten through simulation when the pitch curve of the gear Shaper rolled on the equivalent planar pitch curve. The design of noncircular bevel gear was transformed into the design of the equivalent stud gear. This method simplifies the design of noncircular bevel gear.
