基于VBA的格里森弧齿锥齿轮计算机辅助设计系统

A ComputerAided Design System of Gleason Spiral Bevel Gear Based on VBA

弧齿锥齿轮几何形状复杂,参数多且计算繁琐。基于VBA开发了一套格里森弧齿锥齿轮的计算机辅助设计系统,可快速实现所有几何尺寸计算、强度计算、参数化绘制零件工作图、切齿参数计算等,大大提高了设计速度和准确性。讨论了系统的总体结构和主要功能。

Because spiral bevel gear has complex geometrical shape, many parameters and the calculating process more complicated , a computer aided design system of Gleason spiral bevel gear using VBA is developed which can raoidlv make geometrv calculation, strenath calculation, oarameterized drawing of mechanical parts, cutting parame-ters calculation, and so on. Thus it greatly improves the speed and accuracy of design. The overall structure and main functions of the system are discussed in this article.
