在高速和轻载工况条件下,打滑擦伤往往成为圆柱滚子轴承的主要失效形式,而表面粗糙度对轴承打滑损伤有很大的影响。
Under high speed lightly loaded conditions, skidding damage often becomes one of the main damage forms for cylindrical roller bearings while surface roughness has great effect on skidding damage.
在多冲载荷作用下,零部件大都会在其接触表面出现宏观可见的变形,并引发各种缺陷,从而导致零件损伤失效。
Under the effect of this kind of load, there are microscopic deformations and various disfigurements appear on the contact surface of the parts, and then lead to damage and failure.
使用中的失效形式已不是疲劳剥落,大多是起始于表面损伤一类的故障。
The type of failure in operation is no longer the fatigue spall, but starts Witt the surface damage.
