摘　　要：主要介绍渐开线齿廓齿根过渡曲线的几种形式,描述齿根过渡曲线的成形原理及计算公式,并以齿轮弯曲疲劳强度作为标准,研究滚刀不同圆角大小下齿根过渡曲线对齿根弯曲疲劳强度及相关参数的影响。本文为了解齿根过渡曲线生成过程,掌握齿根过渡曲线规律及滚刀设计制造提供一定方法和思路。This paper introduces several forms of root transition curve of the involute gear,describes the forming principle and calculation formula of the root transition curve,and studies the influence of different hob fillet radius on the root bending fatigue strength and the related parameters.This paper provides some methods and ideas for understanding the generation process and rules of the tooth root transition curve,and for the design and manufacture of the hob.

关 键 词：齿根过渡曲线 齿根弯曲疲劳强度 滚刀圆角
