文档介绍：摘要
齿轮作为最重要的基础传动部件被广泛地应用于机械、冶金、石化、煤炭、水电等行业。在齿轮设计和生产过程中,需要大量的分析、计算和绘图工作。随着计算机技术的飞速发展,使齿轮设计人员借助计算机及相应软件可迅速、高效、准确地进行设计方案的确定、比较、分析和绘图,为生产企业以高技术、高质量、低成本占领市场提供技术保障。
,调用Solidworks API函数对Solidworks进行二次开发,实现精确渐开线直齿圆柱齿轮参数化设计,同时以插件的形式实现了与Solidworks软件的无缝集成,从而提高了齿轮三维造型的速度和效率。利用参数化设计生成的齿轮实体,另存为IGS格式文件导入ANSYS软件,根据齿轮的工作情况及失效形式,建立有限元分析模型,对齿根最大弯曲应力有限元分析。最后利用IGS格式文件生成的MCX格式文件,在Mastercam X4软件中利用数控加工自动编程技术对齿轮齿廓进行数控线切割加工指令程序的编制,并进行数控加工仿真。本论文在solidworks平台上实现精确渐开线直齿圆柱齿轮的参数化三维设计的方法和过程,对同类零件的快速设计具有一定的借鉴意义。

Abstract
As the most important foundation of ponents, gear` are widely used in machinery, metallurgy, petrochemical, coal, electricity, etc. Gear design and production process needs a large number of analysis, calculation and mapping work. With the rapid development puter technology, gear designers puter and the corresponding software can be quickly and efficiently and accurately to confirm, compare, analyze and draw the design proposal, which provide technical support for production enterprise occupy market with high technology, high quality and low cost.
This paper discusses using the development tools of to call API function of Solidworks for secondary development realize the parametric design of precise involute gear, and meanwhile forming the plug-in to achieve seamless integration with the Solidworks software, so it will improve designing the three-dimensional model of gear speedy and efficiently. By using the parametric design of gear entity saved as IGS format file import ANSYS software. According to the working conditions and gear failure form build analysis model of finite element to analyze the maximum bending stress of gear root. Finally, using the MCX format file which generated by the IGS format file C cutting machining instructions of gear tooth profile under the technology C automatic programming, and go on NC machining simulation in the Mastercam X4 software. on the platform of solidworks achieving
