摘　　要：在计算椭圆齿轮齿形坐标时,采用先计算椭圆齿轮节曲线上齿形中点的曲率半径和曲率中心的坐标,作为当量齿轮的分度圆半径和当量齿轮的几何中心,从而直接引用渐开线直齿圆柱齿轮齿形设计方法,并进行坐标变换,从而求得椭圆齿轮齿形的坐标,并利用计算机绘制出齿形,这种设计计算方法不仅结果精确,而且其设计程序具有通用性。In order to obtain the tooth curves of elliptic gear, the coordinate for radius and center of curvature of the pitch cur in the middle tooth profile are first calculated and then used as standard pitch circle radius and geometry center of the equivalent spur gear. Based on the theory of designing the involute tooth of spur gears, the tooth curves of the elliptic gear can be obtained after coordinate transformation and sketched by the computer. This method has the advantage of precise results and generalized program.
