摘     要

 本文是对等共轭曲率环面蜗杆蜗轮啮合理论的研究，主要是以4阶接触为重点，建立自然齿形的“泛函”数学模型和计算方法。构造高阶啮合基准蜗杆齿形。根据计算出来的齿形设计高阶啮合共轭蜗轮蜗杆的刀具并加工高阶啮合共轭齿轮。独到地将微分几何“切触”概念应用于齿面接触分析。用蜗轮蜗杆仿形原理和高阶接触原则形成重载蜗轮蜗杆的自然（稳态）齿形一整套理论、方法及其实现。生产两个高阶接触蜗轮蜗杆加工刀片和加工两个高阶接触蜗轮蜗杆。并且运用VB程序的编写，从而进行对等共轭齿形的绘制，以及编写基准蜗杆的坐标数据。最后找到一种设计方法，使蜗轮蜗杆啮合表面能够得到尽可能高的接触阶数（接触得尽可能更紧密但不完全贴合），提高其接触强度和润滑效果。

This article is a torus, such as conjugate meshing Worm theoretical research, mainly focusing on contact of order 4, the establishment of the natural profile of the "functional" mathematical models and calculation methods. High-end benchmark structure worm tooth meshing. Calculated in accordance with the design of high-profile worm conjugate meshing tool and high-level processing of conjugated gears meshing. Unique differential geometry to "touch" concept applies to tooth contact analysis. Worm profiling using high-end principle and the principle of the formation of heavy exposure to the natural worm (state) profile a set of theories, methods and its realization.
 The production of two high-end processing blade contact with worm gear and processing high-level contact with the two worm. And procedures for the preparation of the use of VB in order to carry out, such as the mapping conjugate tooth, as well as coordinates the preparation of baseline data worm. The final design to find a way to worm gear mesh surface can be the highest possible order of contact (as much as possible exposure to a closer fit, but not exclusively), to increase their exposure to the effect of strength and lubrication.
