实际上该搅拌车滑动轴承的早期损坏比轴承烧坏更常见，因此防止滑动轴承的早期损坏非常重要。那么水泥自上料搅拌车滑动轴承损坏如何处理？

In fact, the early damage of the sliding bearing of the mixer is more common than the bearing burning, so it is very important to prevent the early damage of the sliding bearing. How to deal with the damage of the sliding bearing of the cement self feeding mixer?

滑动轴承在气缸压力冲击载荷的反复作用下，表面层发生塑性变形和冷作硬化，局部丧失变形能力，逐步形成条纹并不断扩展，然后随着磨屑的脱落，在受载表面层形成凹穴。

Under the repeated action of the cylinder pressure impact load, the surface layer of the sliding bearing undergoes plastic deformation and cold work hardening, loses the deformation ability locally, gradually forms stripes and continues to expand, and then forms cavities on the loaded surface layer as the wear debris falls off.

一般轴瓦发生穴蚀时，是先出现凹坑，然后这种凹坑逐步扩大并引起合金层界面的开裂，裂纹沿着界面的平行方向扩展，直到剥落为止。

In general, when the bearing bush is cavitated, the pit first appears, and then this pit gradually expands and causes the alloy layer interface to crack. The crack extends along the parallel direction of the interface until it is peeled off.

滑动轴承穴蚀的主要原因是，由于油槽和油孔等结构要素的横断面突然改变引起油流强烈紊乱，在油流紊乱的真空区形成气泡，随后由于压力升高，气泡溃灭而产生穴蚀。

The main reason for cavitation of sliding bearing is that the sudden change of cross section of structural elements such as oil groove and oil hole causes a strong disorder of oil flow, forming bubbles in the vacuum area where the oil flow is disordered, and then cavitation occurs due to bubble collapse due to pressure rise.

穴蚀一般发生在轴承的高载区，如曲轴主轴承的下轴瓦上。轴承走外圆轴承走外圆就是轴承在座孔内有相对转动。

Cavitation usually occurs in the high load area of the bearing, such as the lower bearing pad of the crankshaft main bearing. The bearing moves in the outer circle. The bearing moves in the outer circle, which means that the bearing rotates relatively in the seating hole.

轴承走外圆后，不仅影响轴承的散热，容易使轴承内表面合金烧蚀，而且还会使轴承背面损伤，严重时烧毁轴承。其主要原因是，轴承过短、凸榫损伤、加工或者安装不符合规范等。

After the bearing goes to the outer circle, it will not only affect the heat dissipation of the bearing, which is easy to ablate the alloy on the inner surface of the bearing, but also damage the back of the bearing, which will burn the bearing in serious cases. The main reasons are that the bearing is too short, the tenon is damaged, and the processing or installation does not conform to the specifications.

滑动轴承的正确维护是减少轴承早期损坏的有效途径，也是延长轴承寿命的可靠保证。

The correct maintenance of sliding bearing is an effective way to reduce the early damage of bearing, and also a reliable guarantee to extend the service life of bearing.

因此，在发动机的日常维护和维修中，须注意轴承的合金表面、背面、端头及边缘棱角处的外观形状。

Therefore, in the daily maintenance and repair of the engine, attention must be paid to the appearance of the alloy surface, back, end and edge corners of the bearing.

如有异常或出现过半磨损的征兆，就要认真查明原因，并采取相应的措施，改善轴承的工作条件，重视对滑动轴承早期损坏的预防。更多相关事项就来我们网站http://www.sdzkjf.cn咨询吧！
