Analysis of the forming principle of tooth flank of modified type worm gear pair was based on different geometry and spatial engaging theory.

基于微分几何和空间啮合理论，分析了修正型圆环面双包络环面蜗杆副齿面形成原理。

Thus it can been seen that, after mending tooth shape of the worm, the Wildhaber-worm gear pair sensitivity to errors has been greatly reduced.

由修形后传动副的接触状态分析可见，传动副对误差的敏感性已大大降低。
