摘　　要：利用D-H坐标系建立弧面凸轮的轮廓方程和共轭接触线方程。充分利用球形滚子的几何特征,先绘制中心轨迹线,然后通过Pro/E软件建立弧面凸轮的三维实体模型,从而为实现弧面凸轮的数控加工、该机构的动力学分析和运动仿真等奠定了基础。After deeply studying the working principle of new type of indexing mechanism with globoidal cam,the equations of the contour surface and the conjugate contact line are established using D-H coordinate system.Taking full advantage of the roll’s geometry character,the track of centre line is drawn,and then the 3D model of globoidal cam is built using Pro/E software quickly.Thus the foundation is established to implement the numerical control machining,to carry through dynamics analyze and motion simulation a...
