摘　　要：提出了一种具有滚动齿的新型锥面包络蜗杆分度凸轮机构 ;推导了滚动齿廓面、凸轮廓面方程 ;引入媒介点啮合理论 ,求出共轭曲面的接触迹 ;给出滚动齿的结构设计方案。In this paper, a new type of conical envelope worm indexing cam mechanism with rolling teeth is proposed. The indexing plate and indexing cam gear surfaces formulas are derived. The contact tracks of gear surfaces are decided based on the medium conjugate engagement theory. The authors design the rolling teeth's structure of the conical envelope worm indexing cam mechanism.
