摘　　要：精确的齿根过渡曲线对于齿轮弯曲强度的评价具有重要意义。结合机械生产实际,对现有常用的齿轮加工方法及其过渡曲线形式进行分析,从中选取具有代表性的加工方案,据此建立摆线齿轮加工刀具的齿廓模型。根据齿轮啮合理论,推导摆线内齿轮副齿根过渡曲线的参数方程,实现其齿根过渡曲线的精确建模和轮齿弯曲强度的准确计算。A precise root fillet curve has great significance for the evaluation of gear bending strength. According to the actual machinery production,the paper firstly analyzes the common gear machining method and its root fillet curve. Then,it selects a typical machining scheme and establishes the teeth profile model of cycloid gear cutting tool. Finally,it deduces the parametric equation of root fillet curve of internal cycloid gear based on gear meshing theory,and realizes precise modeling and accurate calculation of teeth bending strength.
