摘　　要：为了提高变位齿轮的工程图绘制的速度和精度,在建立变位齿轮的齿根过渡曲线方程的基础上,通过程序完成了变位齿轮的全齿廓数据的精确计算,并利用宏命令接口将数据输入到CATIA中。最后在CATIA中实现了变位齿轮的精确建模和工程图的快速绘制,为后续齿轮的弯曲强度分析、准确加工和尺寸验证奠定了技术基础。In order to improve the speed and precision of drawing the profile shifted gear,a program,based on the establishment of the equation of dedendum trasion,is developed to accurately calculate the coordinates of the whole profile.Through the macro commands,the data of coordinates can be imported to CATIA.At last,the accurate model and fast engineering drawing is set up in CATIA.The way of getting the precise model and engineering drawing of profile shifted gear gives a technical foundation of gear’s bend stress analysis,accurate processing and size verification.
