摘　　要：针对某供热汽轮发电机组小修后出现3号轴承箱振动大的故障现象进行了现场测试,并对其振动特征及故障特征进行了分析。依据现场检查结构调整转子与定子装配情况,对发电机转子进行动平衡,解决了该机组的振动问题。After a little repair on a heat supply turbine-generator set, vibration failure was encountered to its No. 3 bearing housing. Local testing was carried out while an analysis performed on its vibration characteristics and failure trait. Based on local testing results, adjustment was made to the fitting between its rotor and stator, while dynamic balancing performed to the generator rotor, hence the vibration problem solved.
