摘　　要：风电增速箱行星齿轮渗碳淬硬后磨削内孔时,极易产生磨削回火烧伤,其中多数情况下只有通过酸蚀检查才能发现。针对磨削烧伤产生的原因,我们从砂轮、切削参数、冷却方法等方面实施工艺改进,降低了废品率,获得了一定的经济效益。Tempering is very frequent when grinding the internal hole surface of planet gear of wind power speed-increasing gear box after carburizing and quenching.In most cases,it will be checkout with the method of acid pickling only.Aiming at the cause of grinding tempering,the technology improvement is implemented from grinding wheel,cutting parameter and cooling method,etc.The reject ratio is decreased and a certain economic benefit is obtained.
