實際上該自動上料攪拌車滑動軸承的早期損壞比軸承燒壞更常見，因此防止滑動軸承的早期損壞非常重要。

In fact, the early damage of the sliding bearing of the automatic feeding mixer is more common than the burning of the bearing, so it is very important to prevent the early damage of the sliding bearing.

在氣缸壓力沖擊載荷的反復作用下，滑動軸承表層發生塑性變形和冷加工硬化，部分喪失變形能力，逐漸形成條紋并膨脹，然后隨著磨屑的脫落，在受力表層形成空洞。

Under the repeated action of the cylinder pressure impact load, the surface of the sliding bearing undergoes plastic deformation and cold work hardening, partially losing the deformation ability, gradually forming stripes and expanding, and then forming voids in the stress surface with the falling of the wear debris.

一般情況下，軸瓦發生點蝕時，點蝕首先出現，然后點蝕逐漸擴大，導致合金層的界面開裂。裂紋沿界面平行方向擴展，直至剝離。

Generally, when pitting occurs on the bearing bush, pitting occurs first, and then gradually expands, resulting in the interface cracking of the alloy layer. The crack propagates along the parallel direction of the interface until it peels off.

滑動軸承空蝕的主要原因是油槽、油孔等結構元件截面的突變導致油流的強烈無序，在無序的真空區形成氣泡，然后由于壓力升高導致氣泡坍塌而發生空蝕。自動上料攪拌車生產廠家

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

氣蝕通常發生在軸承的高負荷區域，如曲軸主軸承的下軸瓦。軸承外圈是軸承在座孔內的相對轉動。軸承通過外圈后，不僅影響軸承的散熱，容易造成軸承內表面的合金腐蝕，而且會損壞軸承的背面，嚴重時會燒壞軸承。主要原因是軸承太短，榫頭損壞，加工或安裝不符合規范。

Cavitation usually occurs in the high load area of the bearing, such as the lower bearing shell of the crankshaft main bearing. The bearing outer ring is the relative rotation of the bearing in the seat hole. After the bearing passes through the outer ring, it will not only affect the heat dissipation of the bearing, but also easily cause alloy corrosion on the inner surface of the bearing, and will damage the back of the bearing, which will burn the bearing in serious cases. The main reason is that the bearing is too short, the tenon is damaged, and the processing or installation does not meet the specifications.

滑動軸承的正確維護是減少軸承早期損壞的有效途徑，也是延長軸承使用壽命的可靠保證。因此，在自動上料攪拌車發動機的日常保養和維修中，一定要注意合金表面、軸承背面、端部和棱角的外觀形狀。

The correct maintenance of sliding bearings is an effective way to reduce the early damage of bearings, and is also a reliable guarantee to extend the service life of bearings. Therefore, in the daily maintenance and repair of the engine of the automatic feeding mixer, it is necessary to pay attention to the appearance and shape of the alloy surface, bearing back, end and corner.

如果有異常跡象或磨損過半，一定要認真查找原因，采取相應措施，改善軸承的工作條件，注意防止滑動軸承的早期損壞。更多相關攪拌車的事項就來我們網站http://www.www.boy7up.cn咨詢！

If there are abnormal signs or more than half of the wear, it is necessary to carefully find out the cause, take corresponding measures to improve the working conditions of the bearing, and pay attention to prevent the early damage of the sliding bearing.
