对渐开线齿轮动态力研齿进行了理论分析和实验研究。基于以研代磨的设想 ,齿轮动态力研齿将研磨工艺用于硬齿面精加工 ,其加工原理为 ,两被研齿轮在空载下以确定的速比 ,在大转动惯量下高速稳态运转 ,研齿时保持速比不变 ,并周期性改变两齿轮的中心距 ,利用齿轮啮合时齿轮本身误差产生的齿面动态力 ,在研磨剂的作用下 。

A through study for the mechanism of the involute gear lapping with dynamic force was made in theory and test.Based on the view of using lapping instead of grinding,the machining principle of the involute gear lapping with the dynamic force may be described as following.When two gears operate stablly at high velocity(definite speed ratio,i.e.,the tooth ratio of two gears)with great inertia and change their center distance periodically,the gears error can be modified by the dynamic force and abrasive,so higher accuracy of the both gears can be achieved.
