摘要
文章基于SolidWorks软件提出一种渐开线斜齿圆柱齿轮(斜齿轮)三维建模的通用参数化设计方法。该方法利用SolidWorks软件的基本功能,先设置19个全局变量,然后用方程式驱动的曲线分别创建扫描的路径和轮廓,再通过扫描切除和圆周阵列,最终得到渐开线斜齿轮的三维精确模型;该方法在得到渐开线部分精确曲面的同时,得到了齿根过渡部分的精确曲面,由此推导出了渐开线斜齿轮的基圆槽宽半角、基圆半径、导程和渐开线起始圆压力角的表达式。此方法具有简单、快捷、精度高、方便修改等优点,为机械产品的快速设计奠定了基础。
Based on SolidWorks software,a general parametric design method for 3D modeling of involute helical gear is proposed.This method uses the basic function of SolidWorks software to set 19 global variables,and then creates the profile and the path respectively by using the equation driven curves.Through swept cut and circular pattern,the 3D accurate model of the involute helical gear is finally obtained.(Not only the exact surface of the involute part,but also the exact surface of the root transition part are obtained.)The expressions of base circle groove width half angle,base circle radius,lead and pressure angle of initial point of an involute curve are derived.This method has the advantages of simple,fast,high precision and convenient modification,which lays a foundation for the rapid design of mechanical products.
