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。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,a3D parametric design system of cylindrical helical gear is designed.
