机车柴油机曲轴轴系的扭转振动,不仅直接影响柴油机的可靠工作和使用寿命,同时涉及整个机车的振动、噪声,恶化乘务人员的劳动条件。现有内燃机车上柴油机多采用硅油或簧片硅油减振器,由于装用的硅油老化变质,轴套磨耗、渗漏以及簧片断裂等原因,其减振作用将逐渐减弱或消失,使扭振加剧。架修或厂修时,需要确定是否存在上述故障,及其
The torsional vibration of the diesel engine crankshaft system not only directly affects the reliable operation and service life of the diesel engine, but also involves the vibration and noise of the entire locomotive and worsens the working conditions of crew members. Existing diesel locomotive diesel engine or more reed silicone oil shock absorber, due to the aging deterioration of installed silicone oil, bush wear, leakage and reed rupture and other reasons, the damping effect will gradually diminish or disappear, the torsional vibration Exacerbated. Repair or factory repair, you need to determine the existence of these failures, and its
