摘　　要：系统分析了弧面分度凸轮曲面的形成特点,根据空间啮合原理简洁地导出了弧面分度凸轮的廓面方程,利用旋转坐标的方法,建立了凸轮廓面与从动件上特征截面接触点的一般数学模型。在此基础上,提出了弧面分度凸轮实体建模方法,并以Solid Works软件为平台,进行了实例计算。该实体建模方法,为深入研究共轭曲面零件的实体造型问题奠定基础。The paper analyzes the formative characteristics of globular indexing cam contour. It gets the equation of globular indexing cam contour simply according to theory of space engagement and establishes the general mathematic model for the contact points of cam contour surface and characteristic cross- section of followers by rotating coordinates Based on these, the solid modeling method of globular indexing cam is discussed and the model is computed by the software of Solid Works. This solid modeling method builds base for studying the solid modeling problem of conjugate surface parts further.
