【摘要】：汽车主传动锥齿轮包括螺旋锥齿轮传动和准双曲面齿轮传动。准双曲面齿轮传动是汽车主传动锥齿轮传动的通用形式。螺旋锥齿轮传动可作为准双曲面齿轮传动偏置距为零时的特例。与普通锥齿轮相比，准双曲面齿轮重迭系数较大、齿面比压较低、强度高，具有传动平稳、冲击和噪音比较小、承载能力高和寿命长等优点。正是由于这些优点，所以准双曲面齿轮被广泛应用于各种车辆之中，准双曲面齿轮的设计和研究，在机械工业、汽车工业中有着重要的地位和作用。然而准双曲面齿轮的结构相当复杂，其中的设计参数如此之多，给从事准双曲面齿轮设计的工程技术人员带来了很多的困难。本文将运用Visual C++可视化编程工具开发汽车主传动锥齿轮可视化设计系统。本系统将能够方便的完成准双曲面齿轮的几何结构设计、齿面参数主动设计，并能够对建立在几何结构设计和齿面参数设计基础之上的准双曲面齿轮进行误差敏感性分析。 本文在对国内外准双曲面齿轮理论知识和可视化程序设计研究的基础上，从事本文的研究，本文主要完成了以下几方面的工作： （1）对目前我国准双曲面齿轮设计研究的现状，提出了汽车主传动锥齿轮可视化设计的总体思想和研究设计的方案。 （2）对准双曲面齿轮几何结构的基本设计参数、齿面结构参数进行分析，建立几何模型和数学模型，并在此基础上进行了齿面的误差敏感性分析。 （3）经过对可视化程序设计软件的分析和比较，并选取了Visual C++作为开发平台，从而完成了系统各设计模块的功能并保证了系统的开放性。 （4）在设计过程中进行了可视化、智能化的分析，对各个输入的参数进行控制，保证了本系统设计的准确性。 （5）研究开发出了具有实用价值的汽车主传动锥齿轮可视化设计软件，，使得工程技术人员能够更方便快捷的从事齿轮的设计工作。 汽车主传动锥齿轮可视化设计系统是采用面向对象的C++开发，具有模块化程度高、可移植性强、可读性好，易于维护等特点，能方便完成准双曲面齿轮几何结构参数设计、齿面主动设计和基于主动设计的误差敏感性分析。本系统使用方便、界面友好、运行安全可靠，实现了从初始数据输入到参数化设计、参数化绘图。不仅可以节省设计人员的时间和精力，而且对从事齿轮设计的工程技术人员有辅助的作用，缩短了设计开发的周期。
[Abstract]:Automobile main drive bevel gear includes spiral bevel gear drive and hypoid gear transmission. Hypoid gear transmission is the general form of automobile main drive bevel gear transmission. Spiral bevel gear transmission can be used as a special case where the offset of hypoid gear transmission is 00:00. Compared with conventional bevel gears, hypoid gears have higher overlap coefficient, lower specific pressure on tooth surface, higher strength, more stable transmission, lower impact and noise ratio, higher bearing capacity and longer life. Because of these advantages, hypoid gears are widely used in various vehicles. The design and research of hypoid gears play an important role in mechanical industry and automobile industry. However, the structure of hypoid gears is quite complex, and the design parameters are so many that it brings a lot of difficulties to the engineers who are engaged in the design of hypoid gears. In this paper, the visual design system of automobile main drive bevel gear is developed by using Visual C visual programming tool. The system can easily complete the geometric structure design of hypoid gear, the active design of tooth surface parameters, and the error sensitivity analysis of hypoid gear based on geometric structure design and tooth surface parameter design. Based on the theoretical knowledge and visual programming of hypoid gears at home and abroad, this paper is devoted to the research of this paper. The main work of this paper is as follows: (1) for the present situation of hypoid gear design in China, the general idea and research scheme of visual design of main drive bevel gear are put forward. (2) the basic design parameters and tooth surface structure parameters of hyperboloid gear are analyzed, the geometric model and mathematical model are established, and the error sensitivity of tooth surface is analyzed. (3) after the analysis and comparison of the visual programming software, Visual C is selected as the development platform, thus the functions of the design modules of the system are completed and the openness of the system is ensured. (4) in the process of design, the visual and intelligent analysis is carried out, and the input parameters are controlled to ensure the accuracy of the system design. (5) the visual design software of the main drive bevel gear is developed, which makes the engineers more convenient and quick to do the design work of the gear. The visual design system of automobile main drive bevel gear is developed with object oriented C, which has the characteristics of high modularity, high portability, good readability and easy maintenance, and can easily complete the geometric structure parameter design of hypoid gear.
