采用碟形砂轮的面齿轮磨齿方法理论分析

为了制造出高精度硬齿面面齿轮和获得抛物线传动误差并提高传动稳定性,提出一种采用碟形砂轮加工面齿轮的磨齿方法.分析了碟形砂轮磨削面齿轮的展成原理和碟形砂轮的运动,根据展成原理推导了碟形砂轮的齿面方程,使用渐开线失配的碟形砂轮和改变砂轮的运动,推导出双向修形面齿轮的齿面方程.建立了双向修形面齿轮和常规渐开线小齿轮啮合的齿面接触分析模型,齿面计算和齿面接触分析实例表明,采用碟形砂轮加工双向修形面齿轮的磨齿方法是可行的,获得了面齿轮抛物线传动误差,避免了边缘接触并提高了传动的稳定性.

Theory analysis for application grinding disk in face gear grinding

A method of tooth grinding for face gear machining by using grinding disk was proposed with the purpose to manufacture hardened face gear with high precision and obtain parabolic transmission errors and increase transmission stability.The generation theory and grinding disk motion of face gear abraded by grinding disk were analyzed,the surface equation of grinding disk was deduced according to the generation theory,and the double crowned tooth surface equation of face gear was derived based on using grinding disk with mismatch involute and modified movement of grinding disk.The model of tooth contact analysis of double crowned face gear meshing with traditional involute pinion was established.Instances of tooth surface calculation and tooth contact analysis indicate that the method of gear grinding applied to manufacture double crowned face gear through grinding disk is feasible,parabolic transmission errors of face gear can be obtained,edge contact is avoided and is enhanced the stability of transmission.
