发动机轴瓦在正常使用过程中,将逐渐磨损直至最后失去工作能力,自然的结束其使用寿命。发动机安装调整不当、润滑油品质不良、使用条件恶劣等因素,都会促使轴瓦过早的磨损或出现种种损伤,这不仅要影响发动机的正常工作,同时也将大大的降低其轴瓦的使用寿命。因而,在进行发动机保养解体检视时(如二级保养前发现有“瓦响”故障,为消除轴承间隙过大,需解体、清洗曲柄连杆机构,检查轴颈及轴瓦,据情拆除适当厚度的轴承垫片,
In the normal process of using the engine bearing, it will gradually wear until it finally loses its working capacity and naturally ends its service life. Improper installation of the engine, poor quality lubricants, poor conditions and other factors, will lead to premature bearing wear or damage, which not only affect the normal operation of the engine, but also will greatly reduce the service life of its bearings. Therefore, during the disassembly of engine maintenance inspection (such as the two maintenance before the discovery of “tile ring” failure, in order to eliminate the bearing clearance is too large, the need to disintegrate, cleaning the crank and rod mechanism, check the journal and bush, according to the situation removed the appropriate thickness Bearing pads,
