用旋转变换张量法计算圆柱凸轮分度机构的压力角

Calculate Pressure Aogle of Cam Index Mechanism of Cylinder Using Spinning Alternate Tensor Method

圆柱凸轮分度机构的主要设计方法是解析法。在解析法中该种机构的压力角计算较困难。用旋转变换张量法计算压力角、概念明确、简单明了。本文最后提出了各种圆柱凸轮分度机构压力角的计算式和最大压力角搜索范围，以便设计使用。

The main designing way of Cam index mechanism of cyl-inder is analytic method, in which the calcutation of pressure, angle .of this mechani is rclatively difficult Using Spinning altemate tensor method to fo calculate pressurc angle is simple and rcasonable. Finally, this paper .puts forward the calcuiation Patlern of pressure angle of earn index mechanism of cylinder and the arching scope off biggest pressure angle for the sake of design.
