摘　　要：兆瓦级双馈机组齿轮箱高速轴轴系随运行年限增加出现断齿、窜动、轴承高温、轴承跑圈等故障。针对这些问题,根据实际运行数据,从轴系润滑、轴承装配、对中维护三方面分析故障原因,提出齿轮箱“四步”清洗、轴承孔金属修复、安装窜动预警装置等维护、保养和预防措施。机组实际运行结果证明该方法有效,可供技术人员在解决类似问题时参考。With the increase of operation years,the high-speed shaft system of the gearbox of megawatt doubly fed unit has faults such as tooth breakage,runout,high temperature and bearing race in bearing.This paper transforms the idea.Combined with the actual operation data,it analyzes the fault causes from the three aspects of shaft lubrication,bearing assembly and centering maintenance,and creatively puts forward the preventive measures of gearbox cleaning,bearing hole metal repair and installation of runout early warning device.Finally,the actual operation proves that the improved method is effective,which can be used as a reference for technicians in solving similar faults.
