摘　　要：针对风电变桨轴承用超大尺寸保持架在使用过程中存在明显的接触变形,甚至有金属颗粒脱落的现象,进行了一系列的对比试验及分析,以确定一种更优化的保持架表面处理方法。结果表明,表面塑化处理技术可显著提高保持架的耐磨性、耐冲击性和抗变形能力,进而保证轴承具有长使用寿命及高可靠性。A series of comparative experiments and analyses were conducted to determine a more optimized surface treatment method for the oversized cage used in wind turbine pitch bearings,which exhibits significant contact deformation and even metal particle detachment during use.The results indicate that surface plasticization treatment can significantly improve the wear resistance,impact resistance,and deformation resistance of the cage,thereby ensuring the long service life and high reliability of the bearing.
