Combining with the fast elitist non??dominated sorting genetic algorithm II, an antiscuffing optimization schedule of tooth modification for face gear drives is constructed by regarding eight parameters of curves on modified pinions as the optimization variables and the minimum tooth surface flash temperature as the optimization objective. The calculations examples show that the flash temperature on the contact ellipse long axes near the pitch cone approaches 0℃, the farther the contact ellipse long axis from the pitch cone, and the higher the sliding velocity and flash temperature on the contact ellipse long axis, the scuffing failure is more prone to occur on the mesh??out contact elliptical long axis. Once optimizing the modification parameters of the pinion, the maximum tooth surface flash temperature decreases by 29.9%, thus improving the antiscuffing capacity of face gear drives %K 面齿轮传动 %K 齿面闪温 %K 修形 %K 抗胶合 %K 优化 %K 非支配排序遗传算法< %K br> %K face gear drive %K tooth surface flash temperature %K modification %K anti??scuffing %K optimization %K non??dominated sorting genetic algorithm II %U http://zkxb.xjtu.edu.cn/oa/DArticle.aspx?type=view&id=201811018
