基于UG的渐开线直齿圆柱齿轮参数化精确造型设计

摘要

介绍了一种利用UG的表达式和规律曲线功能建立直齿圆柱齿轮模型的方法。该方法绘制了精确的齿廓曲线，生成的齿廓各段曲线不需任何修剪便可直接建立精确的齿轮模型。并可通过改变模数和齿数等参数，使生成的模型自动更新，实现了建立模型的真正参数化。%Describe expressions and laws of a UG curve method of straight tooth cylindrical gear model features.The method draws the exact tooth profile curve,tooth profile curve generating directly without any pruning can establish accurate gear models, and by changing parameters such as module and number of teeth, the generated model automatically updates, to achieve the establishment of models for real parameter.
