齿轮三维模型的参数化设计技术

Parametric Design of 3D Gear Model

齿轮是汽车、拖拉机中常用的传动零件,在三维设计中,需要对渐开线方程进行转换,由转换后的方程生成齿形,其整个设计过程非常繁琐。本文详述了方程的转换过程及齿轮的参数化设计方法,可以通过输入不同的齿轮参数,即可获得相应的齿轮,从而大大节约设计时间。该方法还可应用于所有系列化的通用件和标准件三维设计中。

Gears are common transmission components used in automobile and tractor, In the 3D design of a gear,the involute equation of a gear should be transformed, and the teeth are generated according to the transformed equation. The whole design procedure is very complex. The transforming procedure of involute equation and the parametric design method of gear are discussed in detail, The desired gears can be obtained by inputting different gear parameters. The design time can be largely saved by means of this method, Similarly, the method can also be applied to all 3D design of serial general-purpose and standard components.
