摘　　要：通过对某电厂亚临界325MW汽轮发电机组轴系发生油膜振荡故障案例进行整理,归纳分析了油膜涡动和油膜振荡事故原因,给出了引起汽轮机轴系油膜振荡的定性原因分析,提出了增大油孔尺寸、提高润滑油温度、减小轴承顶隙间隙值等的处理措施,为机组安全稳定运行提供技术保证。After analyzing the case of a 325MW turbo generator unit with oil whip in the bearing, causes are concluded. Reason determination analysis is made. And to enlarge oil holes, reduce bearing width, increase lube temperature, shorten the clearance at the top of bearing and etc. Are brought forth as solutions to technically ensure that the unit could run safely and stably.
