【摘要】：随着现代制造行业产品更新换代速度的不断加快，依靠传统的设计方法已跟不上社会对产品变化的需求。CAD参数化设计已经成为当今机械设计领域中十分重要的一个发展方向，并开始逐步替代传统的机械设计方法，被人们越来越多地应用到各行各业中。CAD参数化设计具有设计周期短、效率高，并且直接可以在计算机软件中进行产品的检验与分析等特点，，这就使其更加符合现代制造行业对产品设计的要求。 齿轮作为传动装置当中最为常见的一种零件，具有效率高、可靠性高、使用寿命长等优点，应用范围非常广泛。其中人字形齿轮在船舶、煤矿机械等行业中更是十分常见，并且由于人字形齿轮有传递功率高、运转平稳、噪音低、轴向力能够抵消等优点，它在其它行业中的应用也正在逐步增加。 本文主要是应用UG6.0对人字形齿轮参数化设计及动、静力学仿真进行研究，主要研究内容包括： 1)通过与斜齿轮传动特性的对比，分析出人字形齿轮传动特性的计算公式，及齿轮参数选择的依据。 2)给出在UG环境中人字形齿轮的总体设计思路，建立了人字形齿轮的渐开线、过渡曲线和螺旋线等关键曲线的数学模型，并通过“关系表达式法”对人字形齿轮进行参数化三维建模； 3)对人字形齿轮进行虚拟啮合装配，并对其进行干涉分析检查，判断装配的正确性，利用ADAMS软件，对人字形齿轮受力状态进行动力学仿真分析，验证齿轮设计的合理性； 4)应用ANSYS Workbench软件分析人字形齿轮在静力状态下的装配模型，获得其啮合特性。 通过人字形齿轮受力状态和啮合特性的分析，对人字形齿轮的结构性能有了更深的了解，为人字形齿轮的设计提供了参考依据。
[Abstract]:With the continuous acceleration of product renewal in modern manufacturing industry, relying on traditional design methods has been unable to keep up with the social demand for product changes. CAD parametric design has become a very important development direction in the field of mechanical design, and began to gradually replace the traditional mechanical design method, which has been more and more applied to various industries. CAD parametric design has short design cycle and high efficiency. And the characteristics of product inspection and analysis can be carried out directly in computer software, which makes it more in line with the requirements of modern manufacturing industry for product design. Gear, as the most common part of transmission device, has the advantages of high efficiency, high reliability and long service life, and has a wide range of applications. Herringbone gears are more common in ships, coal mining machinery and other industries, and because of the advantages of herringbone gears, such as high transmission power, stable operation, low noise, axial force can offset and so on, its application in other industries is also gradually increasing. In this paper, UG6.0 is used to study the parametric design and dynamic and static simulation of herringbone gear. The main research contents are as follows: 1) by comparing with the transmission characteristics of helical gear, the calculation formula of herringbone gear transmission characteristics and the basis of gear parameter selection are analyzed. 2) the overall design idea of herringbone gear in UG environment is given, and the mathematical models of involute, transition curve and helix of herringbone gear are established, and the parametric 3D modeling of herringbone gear is carried out by "relational expression method". 3) the virtual meshing assembly of herringbone gear is carried out, and the correctness of assembly is judged by interference analysis, and the dynamic simulation analysis of the stress state of herringbone gear is carried out by using ADAMS software to verify the rationality of gear design. 4) the assembly model of herringbone gear in static state is analyzed by ANSYS Workbench software, and its meshing characteristics are obtained. Through the analysis of the stress state and meshing characteristics of herringbone gear, the structure and performance of herringbone gear are better understood, which provides a reference for the design of herringbone gear.
