實(shí)際上該攪拌車滑動(dòng)軸承的早期損壞比軸承燒壞更常見，因此防止滑動(dòng)軸承的早期損壞非常重要。那么水泥自上料攪拌車滑動(dòng)軸承損壞如何處理？

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?

滑動(dòng)軸承在氣缸壓力沖擊載荷的反復(fù)作用下，表面層發(fā)生塑性變形和冷作硬化，局部喪失變形能力，逐步形成條紋并不斷擴(kuò)展，然后隨著磨屑的脫落，在受載表面層形成凹穴。

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.

一般軸瓦發(fā)生穴蝕時(shí)，是先出現(xiàn)凹坑，然后這種凹坑逐步擴(kuò)大并引起合金層界面的開裂，裂紋沿著界面的平行方向擴(kuò)展，直到剝落為止。

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.

滑動(dòng)軸承穴蝕的主要原因是，由于油槽和油孔等結(jié)構(gòu)要素的橫斷面突然改變引起油流強(qiáng)烈紊亂，在油流紊亂的真空區(qū)形成氣泡，隨后由于壓力升高，氣泡潰滅而產(chǎn)生穴蝕。

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.

穴蝕一般發(fā)生在軸承的高載區(qū)，如曲軸主軸承的下軸瓦上。軸承走外圓軸承走外圓就是軸承在座孔內(nèi)有相對(duì)轉(zhuǎn)動(dòng)。

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.

軸承走外圓后，不僅影響軸承的散熱，容易使軸承內(nèi)表面合金燒蝕，而且還會(huì)使軸承背面損傷，嚴(yán)重時(shí)燒毀軸承。其主要原因是，軸承過短、凸榫損傷、加工或者安裝不符合規(guī)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.

滑動(dòng)軸承的正確維護(hù)是減少軸承早期損壞的有效途徑，也是延長軸承壽命的可靠保證。

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，在發(fā)動(dòng)機(jī)的日常維護(hù)和維修中，須注意軸承的合金表面、背面、端頭及邊緣棱角處的外觀形狀。

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.

如有異常或出現(xiàn)過半磨損的征兆，就要認(rèn)真查明原因，并采取相應(yīng)的措施，改善軸承的工作條件，重視對(duì)滑動(dòng)軸承早期損壞的預(yù)防。更多相關(guān)事項(xiàng)就來我們網(wǎng)站http://f3328.cn咨詢吧！
