摘　　要：探讨了125 MW机组发电机后轴承轴向振动的机理,提出在现场消除后轴承轴向振动的原则;阐述了由振动矢量来诊断轴系不平衡振源的方法和应选择的加重方式,并对现场多次采用而行之有效的简易轴系平衡的依据和实施办法作了介绍,对以后处理类似振动现象有一定的借鉴价值。The cause of the 125 MW Unit axial vibration is deeply discussed in the paper and the measures of suppressing the malfunction are also suggested. In this paper accurate dynamic balances are also introduced. The detailed treatment methods are proposed. It will be beneficial for the same problems.
