摘　　要：探讨了凸角型滚刀的齿形特点,基于齿轮啮合原理,利用坐标转换推导凸角型滚刀所加工出齿轮的齿形曲线方程。通过VB对AutoCAD的二次开发,精确模拟出被加工齿轮齿形曲线。通过分析该齿形曲线与凸角部分的几何构型之间的关系推导出确定被加工齿轮根切量的计算式,对进行滚刀设计和被加工齿轮齿根强度分析具有积极意义。The features of tooth profiles of protuberance type hobs are discussed. Based on principle of bobbing, the tooth pro- file equations of gear machined by protuberance type hobs are derived through coordinate conversion. The profile curves of ma- chined gear is drawed accurately with the secondary development of AutoCAD by using VB. Through analysis of relation be- tween the profile curves and geometric structure of protuberance part, the calculation formula of undercut value is derived, which paves the way for the study of hob designing and analysis of tooth root intensity of machined gear.
