摘　　要：旋转机械运行工况复杂,转子出现不对中后,引起设备的振动、联轴器的偏转、轴承的磨损和油膜失稳、转轴的挠曲变形等,危害极大。通过整理总结大型旋转机械不对中故障案例,归纳分析了不对中原因、振动特征。根据分析结果,总结提出了不对中故障诊断的依据和预防不对中故障的措施,为大型旋转机械安全运行提供技术参考与借鉴。In the complex operation conditions of the rotary machines, when the rotors appear the misalignments, it will cause the vibration of the equipment, the deflection of the coupling, the wear of the bearing, oil film instability and the deformation of shaft. Through studying domestic and foreign misalignments fault cases, the reasons for the misalignment and the vibration features are summarized. Based on the analysis, this paper presents the base for fault diagnosis of the misalignments and measures for the prevention of the misalignments, providing technical references for the safe operation of the rotary machines.
