滚动轴承损坏的原因很多,例如疲劳、磨损、塑性变形、润滑不良、污垢、装配不当和轴承带电等。如果轴承的装配和维护是合适的话,轴承损坏的原因主要是疲劳造成的。滚动轴承产生疲劳,一般是,当在滚动件和与其接触的表面上存在夹杂、孔洞或偏析时,在周期性交变应力作用下,首先以缺陷为核心,形成裂纹,逐步扩展为鳞片状剥落,在轴承的滚道或滚动体的表面形成麻 Rolling bearing damage for many reasons, such as fatigue, wear, plastic deformation, poor lubrication, dirt, improper assembly and bearing live and so on. If the bearing assembly and maintenance is appropriate, the main cause of bearing damage is caused by fatigue. Rolling bearing fatigue, generally, when there are inclusions, holes or segregation in the rolling contact with the surface, under the action of periodic alternating stress, the first to defect as the core, the formation of cracks, and gradually expanded to scale flaking, in the Bearing raceway or rolling the surface of the formation of hemp
