摘要
首次提出渐开螺旋面点接触逆式外啮合，论述了其啮合的几何原理．给出了基本几何关系式、压力角公式，对应点方程．
The counter outside engagement of involute helicoids on point is proposed the first time and its geometric principle is discussed. The basic geometric equations, the pressure angle equations and the conjugate corresponding-point formulas are presented
