基于Pro/E的直齿轮的参数化建模

Parameterized Modeling of Spur Gears Based on Pro/E

为解决传统齿轮设计方法复杂、周期长、工作效率低等问题,应用Pro/E软件按照齿轮参数的初始化,创建四个基本圆、渐开线生成、齿轮轮廓和倒角、镜像渐开线、切齿槽、复制齿槽特征、阵列齿形、创建轴孔和键槽等一系列步骤实现直齿圆柱齿轮的三维参数化设计,并进行了参数化驱动测试,绘制了不同参数的直齿轮三维模型。

In order to solve the problems that traditional design method of spur gears are complicated, long period, and low working efficiency, we can apply Pro/E soft to initialize parameters of spur gears, create four fundamental circles, generate involute, contour gear and chamfer, create image of in-volute, cut gear groove, copy character of gear groove, create tooth profile, create shaft hole and keyway etc. 3D parametric design of spur gears can realize through a series of those steps. We do parametric drive test, and also draw the 3D models of spur gears according to the different pa-rameters.
