基于特征的参数化实体建模技术在齿轮造型中的应用

Design of the Gear Parameter Modeling Based on the Feature Solid Unit

渐开线齿轮齿型比较复杂,大多数三维建模系统都不能直接生成齿轮的三维齿廓,为此,本文基于Pro/E操作平台,将齿轮分解为齿轮毛坯特征和其它一些简单的特征,并对毛坯特征进行参数化设计,使用户只须输入齿轮基本参数即可得到精确的齿轮模型,为齿轮的并行设计提供了简单、快捷的方法。

Because of the complicated involutes linear, the 3 - D gear profile can＇ t be established when the gear modeling is created. Based on Pro/E, the gear was decomposed to the rough features and some simple features, then the first features were designed with parameters, so the user can get the accurate gear modeling only entering the gear parameter. This method is simple and fast for the gear concurrent design.
