斜齿椭圆齿轮设计及其加工方法研究

Design and processing method research of helical elliptic gear

介绍了斜齿椭圆齿轮齿廓的形成原理,分析了用斜齿条加工斜齿椭圆齿轮时齿条与椭圆齿轮坯的运动几何关系。借助AutoCAD基于VBA的二次开发功能进行斜齿条刀具与齿轮坯的实体建模,并用实体的布尔运算模拟展成法加工齿轮时齿条与齿轮坯的范成运动加工出斜齿椭圆齿轮的实体模型。

The profile forming principle of helical elliptic gear was introduced and the motion relation between rack and rough elliptic gear was analyzed. The solid modeling of rough elliptic gear and the solid modeling of bevel rack were founded based on the function of the secondary development for A utoCAD VBA. Then, the solid modeling of helical elliptic gear was gotten by using the Boolean operation to simulate the generating machining process.
