摘　　要：以微分几何与空间啮合理论为基础,推导指状锥面二次包络圆柱蜗杆传动两次包络过程中的啮合方程和主要啮合性能指标方程,通过实例绘出蜗杆副啮合过程中根切界限线和接触线的分布区域,分析总结了润滑角和诱导法曲率的变化规律。Based on differential geometry and spatial engaging theory,a set of formula of finger conical surface double enveloping worm gearing is derived.Through an example,the undercutting boundary line and contact line are depicted.At the same time,the variation law of the lubricating angle and the inductive normal curvature is analysed.
