要
伴随着我国汽车制造行业的快速发展，齿轮作为汽车所有零配件里最重要的部 件， 其设计原理和加工方法的选择也越来越受重视。 摆线齿锥齿轮和准双曲面齿轮 （以 下简称锥齿轮）由于其承载能力高、传动平稳、噪音小、结构紧凑等优点，逐渐在汽 车后桥传动上得到了广泛的应用。 摆线齿锥齿轮的几何参数设计及加工调整参数计算 的精确性直接影响了锥齿轮啮合传动质量、工作寿命及可靠性等。 目前在国际的摆线齿锥齿轮制造生产中， 较为广泛使用的是克林贝格公司的 CDS 摆线锥齿轮设计系统软件。 但是由于齿锥齿轮的设计与加工技术一直以来被瑞士前奥 利康公司及德国的克林根贝格公司所垄断，流入国内的技术资料十分有限，国内学者 对该领域的研究也相对较少，所以对其铣齿加工原理、调整计算、成套加工设备制造 方面的技术掌握都十分不足，与国外先进水平相差很大。目前国外广泛采用全数控机 床加工摆线齿锥齿轮，该方法加工效率高，加工出的锥齿轮的精度较好。国内还主要 采用传统的摆线齿锥齿轮铣齿机加工摆线齿锥齿轮， 而对全数控加工摆线齿锥齿轮的 研究较少，因此研究摆线齿锥齿轮的几何参数、调整参数计算和全数控加工摆线齿锥 齿轮的原理，对加速国产全数控摆线齿锥齿轮铣齿机及其成套设备的开发，提高我国 摆线齿锥齿轮的加工水平具有重要的意义。 本文根据齿轮啮合理论及相关手册， 对摆线齿锥齿轮几何参数设计和计算切齿调 整参数进行理论研究。在此理论研究的基础上，建立奥利康制摆线齿锥齿轮齿面几何 参数如径矢、法矢等的统一计算模型，分析了其求解方法，并根据该模型进行齿面接 触分析研究。 在以上的理论研究基础上， 应用 Visual C++编程工具， 研发出在 Windows 环境下的摆线齿锥齿轮设计软件系统。 通过对摆线齿锥齿轮全数控加工的机床控制原 理研究，建立了摆线齿锥齿轮全数控加工的数学模型，并根据该模型研究了摆线齿锥 齿轮全数控加工的刀位计算方法。根据摆线齿锥齿轮全数控加工控制原理，在 VERICUT 数控仿真软件构建了摆线齿锥齿轮全数控加工虚拟切齿平台，并进行切齿 仿真实验， 验证了该摆线齿锥齿轮全数控加工的数学模型和摆线齿锥齿轮设计软件系 统计算的正确性。 关键词：摆线齿锥齿轮；齿轮设计；调整参数；全数控加工

Abstract
As the rapid development of the automobile manufacturing industry, as the most important part of the automobile accessories, the development of gear’s design and machining mode has got more attention than before. The epicycolid bevel gear and hypoid gear (bevel gear for short hereinafter) is widely used in the rear axle of the transmission. Its advantages as great carrying capacity, steady driving system, low noise, and compact conformation make it an important accessory of the vehicle power transmission system. Bevel gear's geometric parameter design and processing adjustment parameter transmission performance evaluation and so on computation accurate immediate influence bevel gear meshing transmission quality, working life and reliability key parameters. At present, the Klingelnberg corporation’s CDS software is widely applied in the international epicycolid bevel gear and hypoid gear manufacture industry. Because the bevel gear’s designing and machining technique are monopolized by Switzerland ex-Oerlikon corporation and German Klingelnberg corporation. the technical data drifting into China is limited, Chinese scholars in the field study also relatively small, The researches about this area are less in home, therefore the principle of its milling process, adjusting the terms of the manufacture of complete sets of processing equipment to master the technology are less, and foreign advanced levels vary considerably. At present overseas widely uses the entire numerically-controlled machine tool processing cycloidal tooth bevel gear, this method processing efficiency is high, bevel gear's precision which processes is good. The home also mainly uses traditional the cycloidal tooth bevel gear milled tooth machining cycloidal tooth bevel gear, but are few to the entire numerical control processing cycloidal tooth bevel gear's research, Therefore research cycloidal tooth bevel gear's geometric parameter, adjustment parameter computation and entire numerical control processing cycloidal tooth bevel gear's principle, to accelerates the domestically produced entire numerical control cycloidal tooth bevel gear gear cutter and complete set of equipment's development, raising our country cycloidal tooth bevel gear's processing level to have the vital significance. This article first according to the gear meshing theory and the related handbook, conducts the fundamental research to the cycloidal tooth bevel gear geometric parameter design and the computation cutting tooth adjustment parameter. In this fundamental research foundation, it establishes Oerlikon system cycloidal tooth bevel gear tooth face
