摘　　要：针对不同加工工艺导致圆弧齿线圆柱齿轮齿廓特性存在差异的问题,分析了圆弧齿线圆柱齿轮主要加工工艺(平行连杆加工法和旋转刀盘铣削加工法)的特点,并基于加工成型原理,推导出了两种工艺所得齿轮的齿面和齿廓方程,分别获得了圆弧齿线圆柱齿轮的齿厚和齿厚偏差计算方程,进而分析了齿轮齿宽和齿线半径等设计参数对齿厚和齿厚偏差的影响。研究结果表明:采用平行连杆加工出的齿轮各截面齿廓为渐开线;采用旋转刀盘铣削加工出的齿轮中截面为渐开线,其他截面为双曲线;设计参数对旋转刀盘铣削加工齿轮齿廓特性有一定影响;该研究结果为齿轮润滑、故障诊断及齿廓修形等提供了理论基础。Aiming at the problem that the tooth profile characteristics of the circular-arc-tooth-trace(CATT)cylindrical gear is different due to the different processing technologies,the main processing technologies of the CATT cylindrical gear were analyzed(parallel link machining method and the rotary cutter head milling method).And the tooth surface and tooth profile equations of the CATT cylindrical gears were deduced based on the molding principle of the two processes,and the gear tooth thickness equation and tooth thickness deviation equation of the CATT cylindrical gear were obtained further.The influences of tooth width and tooth line radius on the tooth thickness and tooth thickness deviation were analyzed.The research results show that the tooth profile of CATT cylindrical gear processed by parallel link mechanism is involute in the arbitrary cross section;the middle section of the gear processed by the rotary cutter head milling method is involute,the other sections are hyperbola,and design parameters have a certain effect on the tooth profile characteristics.The research results provide a theoretical basis for lubrication,fault diagnosis and tooth profile modification of the CATT cylindrical gear system.
