如果轴瓦设计和使用得合理,它们的寿命通常比发动机其它部件长。尽管能承受所能产生的不正常的早期故障,但为了排除继续发生故障的原因,必须对其进行检查和改进。产生故障的原因可以从废瓦的状态中得到启发,有些可从完全损坏的轴瓦的外观检查中探讨。通过未完全损坏的轴瓦也可以获得线索。由多种因素造成的故障往往需通过化验和尺寸检查分析。 If the bearings are designed and used properly, they usually have a longer life than the rest of the engine. Despite being able to withstand the abnormal early failure that can occur, it must be inspected and improved to eliminate the cause of the continual failure. The cause of the failure can be inspired from the state of the waste tile, and some can be explored from the visual inspection of a completely damaged bush. Clues can also be obtained from incompletely damaged bushings. Faults caused by a variety of factors often require laboratory and dimensional analysis.
