基于Pro/E的渐开线齿轮参数化设计系统的开发

介绍了在Pro/E环境下,运用圆柱坐标系创建渐开线圆柱齿轮齿廓,利用其开发工具参数(Parameters)结合关系式(Relations)功能来实现渐开线齿轮参数化造型的关键技术;并在研究了Pro/Toolkit特征建模编程原理的基础上,以VC++6.0作为编程语言,实现了利用友好的图形用户界面技术输入设计参数来控制三维实体模型的关键技术。该文以开发渐开线齿轮参数化设计系统(本系统涵盖了直齿、斜齿、蜗轮、蜗杆、锥齿)为实例,详细介绍了这一开发思路和其关键技术。

Development of a parametric function design system of involute gears based on Pro/Engineer

In this paper, the main idea and methods of developing the parametric function design system for the involute gears, such as spur gear, helical gear, worm and wheel gear,and bevel gear,are described based on the developing tools provided by Pro/Engineer,such as parametric functions and relations functions. The method of creating the profile of involute gear by using the cylindrical coordinate system is introduced. The principle of building features elements with Pro/Toolkit is analyzed. By inputting the gear design parameters, the three-dimensional design module is obtained based on the friendly graphical user interface in the VC++6.0 programming environment. With the presented methods,the working efficiency of designers can be greatly improved.
