摘　　要：以Visual Basic 6.0为开发工具,对AutoCAD进行二次开发,研制CHC型少齿差减速器CAD系统。该系统主要包括两大功能模块:设计计算子系统和参数化绘图系统,两者之间通过产品数据库实现有效连接。参数化绘图系统采用ActiveX技术从外部操作AutoCAD的对象,利用开发的底层函数读取零件库中的零件参数,实行零件图的绘制。结合ObjectDBX技术和对象的扩展词典技术实现装配图的绘制,最终实现设计计算和参数化绘图一体化。A CAD system of CHC type reducer with few teeth difference is developed in Visual Basic 6.0 inte- grated prograrnming environment. Two modules, calculating for design and parametric drawing are included in the sys- tem, which are communicated effectively by product database. The ActiveX technology is applied to manipulating Au- toCAD objects in parametric drawing module, and ObjectDBX technology and extending dictionaries technology of ob- ject are also applied to assembling drawing. At last, calculating for design and parametric drawing are integrated effec- tively in the CAD system.
