摘要
应企业实际需求,采用Visual Basic程序语言开发了行星齿轮传动CAD系统。据行星齿轮传动理论,通过编程实现主要零部件尺寸计算和强度校核;由齿面曲线和齿根曲线方程构建实际齿廓曲线,通过二次开发在Solid Works中实现了行星齿轮传动系统各个零件的三维参数化建模,并自动完成装配。结果表明:由建立实际齿廓曲线方程来构建齿轮精确模型的方法可行;行星齿轮传动CAD系统具有的参数化建模功能使出图自动化,提高了设计效率。
For the actual demands of the enterprises the CAD system of the planetary gear train was developed by using Visual Basic programming language. The size calculation and strength check of the main parts were realized by programming based on the theory of planetary gear transmission. The equation of tooth profile curve was built by the equation of the tooth surface and tooth root curve,so three- dimensional parametric modeling of the main parts for the train are achieved through secondary development in Solid Works and the assembly is automatically completed. The results showed that it is feasible to construct the accurate gear model by establishing the actual tooth profile curve equation. The drawing is automatically realized by the parametric modeling in the CAD system and the design efficiency is improved.
