基于VBA专用非圆齿轮CAD/CAM系统的节曲线模块设计

Design of Module of Non-circular Gear Pitch Based on VBA

首先用VBA工具创建一个ActiveX控件,用以读取用户输入的非圆齿轮副传动要求,然后根据用户的传动要求分别对非圆齿轮节曲线进行数学建模,以此为基础,用VBA语言编程,生成节曲线图形子模块,同时设计了节曲线动态参数查询、节曲线滚动仿真和节曲线凸凹校验等子模块,构成了一个完整的节曲线设计模块,为专用非圆齿轮CAD/CAM系统的设计打下了坚实的基础。

Using the tool of VBA for AutoCAD2000,first,create an Active control for acquire equation expression of non-circular gear transmission based on users’desire,Then,create three mathematic model based on users’desire.At last,bade on mathematic model and VBA program,generate graph of pitch.At the same time,in order to be convenience to user,Author also design other subordinate modules,for example dynamic querying about pitch parameter at any time,simulation of pitch rotate,and so on.They will make up of an entirely Module of non-circular gear pitch.
