摘要： 在CAD/CAM/CAE 中，机械产品的三维建模是基础，其精确程度和质量决定着设
计、分析、制造等后续过程的质量。文中讨论了圆柱齿轮中的一类圆柱螺旋齿轮的齿廓曲面的
精确表达，在三维造型软件Pro/Engineer 中的生成方法以及在Pro/Engineer 与C 语言的接口
Protoolkit 中，圆柱螺旋齿轮上的形状结构特征在Pro/Engineer 中的表达、操作、处理函数的功
能和应用开发方法。并以此为例设计了一个圆柱螺旋齿轮的三维参数化设计系统。

Abstract: In CAD/CAM/CAE, the three-dimensional modeling of mechanical products is the key
foundation, its precision and quality determine the quality of the other follow-up design, analysis,
manufacturing and other processes. In this paper discussed are the cylindrical gear in a helical gear
tooth profile surface, accurate expression, generation method in the three-dimensional CAD software
Pro/Engineer and in Pro/Engineer to C language interface Protoolkit, form and structure
characteristics of helical gear expression in Pro/Engineer, operation, treatment function and
application development methods. And taking this as an example, a 3D parametric design system of
cylindrical helical gear is designed.
