为了改善非圆齿轮副设计计算复杂、制造困难的问题,以高阶椭圆非圆齿轮为研究对象,以非圆传动啮合原理为理论基础,探讨非圆齿轮节曲线的计算及设计方法。以SolidWorks为开发平台,在VB 6.0环境下开发了高阶椭圆齿轮副节曲线设计系统,该系统包括参数计算模块、节曲线凹凸性校验以及压力角、根切校验模块、曲线绘制模块等,最终通过三次样条曲线拟合,实现了高阶椭圆齿轮副节曲线计算机辅助设计,从而提高了椭圆齿轮传动设计的效率和精度。

In order to improve the problem of design calculation complex and manufacturing difficulty of non -circular gear pair, taking the high order elliptic non -circular gears as the research object, according to the principle of non - circular gear meshing, the method of calculation and design of the pitch curve of non - circular gear. Taking SolidWorks as a development platform, the high order elliptic gears pitch curve design system is developed in the VB 6. 0 environment, the system includes a parameter calculation module, the pitch curve concavity and convexity check calibration module and pressure angle, root cutting, curve plotting module and so on. Finally, by cubic spline curve fitting, the computer aided design of high order elliptic gear pitch curve is realized, and the efficiency and precision of the elliptical gear drive design are improved.
