导轴承空隙过小，会把转动轴的振动传给支座和基础，导轴承空隙过大，转动轴振动大。
Guide bearing clearance is too small, the vibration of the rotating shaft will be transferred to the bearing and foundation, the bearing clearance is too large, the rotating shaft vibration.
在最后的一次处理中找出机架振动大的根源就是转子磁极松动，导致大轴的摆度加大，下导间隙变大，从而引致机架振动不断增大。
In the last treatment, it was discovered that the problem was caused by loose rotor pole that led to augmented shaft swing and bigger clearance of lower guide bearing.
介绍了大型汽轮发电机组密封瓦振动的机理，经试验分析认为产生振动的原因是密封瓦碰磨、大轴晃度超标。
As a conclusion, the reasons of vibration are that the oil-seal ring create friction and axles flutter exceed standard.
该系统可以监测顶盖、各部轴承、上机架等处的振动速度与大轴摆度。
Such monitoring system includes the vibration protection system and vibration analysis system and can monitor the vibration speed and amplitude in the head cover, bearings, upper holder, etc.
由于制造缺陷，在设备运行中中间轴跳动值超标，从而引起设备振动大而停机。
As the defects produced in its manufacture process, the jumping value of the mean axis was out of the standard during its running, so it gave rise to great vibration of the equipment and stopping.
对于多层建筑物，较高楼层的振动大，轴重大的列车引起的振动较大；
The measured results show that the vibration levels of the environmental ground and building floors increase with the train speed, while attenuating with the distance to the railway tracks;
