自動上料攪拌車滑動軸承損壞怎么辦？

所屬分類：公司新聞 發(fā)布時間：2022-10-14 來源：http://www.ksmayo.cn 瀏覽量：0

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 bearing burning, 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(fù)作用下，滑動軸承表層發(fā)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 with the falling off of the wear debris, a cavity is formed on the stressed surface.
一般情況下，軸瓦發(fā)生點蝕時，點蝕首先出現(xiàn)，然后點蝕逐漸擴大，導(dǎo)致合金層的界面開裂。裂紋沿界面平行方向擴展，直至剝離。
In general, when pitting occurs on the bearing bush, the pitting first occurs, and then gradually expands, leading to the interface cracking of the alloy layer. The crack propagates parallel to the interface until peeling.
滑動軸承空蝕的主要原因是油槽、油孔等結(jié)構(gòu)元件截面的突變導(dǎo)致油流的強烈無序，在無序的真空區(qū)形成氣泡，然后由于壓力升高導(dǎo)致氣泡坍塌而發(fā)生空蝕。自動上料攪拌車生產(chǎn)廠家
The main reason for 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 area, and then cavitation occurs due to the collapse of bubbles due to the pressure rise.

氣蝕通常發(fā)生在軸承的高負(fù)荷區(qū)域，如曲軸主軸承的下軸瓦。軸承外圈是軸承在座孔內(nèi)的相對轉(zhuǎn)動。軸承通過外圈后，不僅影響軸承的散熱，容易造成軸承內(nèi)表面的合金腐蝕，而且會損壞軸承的背面，嚴(yán)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(guī)范。
Cavitation usually occurs in high load areas of bearings, such as lower bearing shells of crankshaft main bearings. The bearing cup is the relative rotation of the bearing in the seating hole. After the bearing passes through the outer ring, it will not only affect the heat dissipation of the bearing, easily cause alloy corrosion on the inner surface of the bearing, but also damage the back of the bearing, and even 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.
滑動軸承的正確維護是減少軸承早期損壞的途徑，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(fā)動機的日常保養(yǎng)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 bearing is a way to reduce the early damage of bearing, and also a reliable guarantee to extend the service life of bearing. Therefore, in the daily maintenance and repair of the engine of the automatic feeding mixer, attention must be paid to the appearance of the alloy surface, the back of the bearing, the end and the corner.
如果有異常跡象或磨損過半，一定要認(rèn)真查找原因，采取相應(yīng)措施，軸承的工作條件，注意防止滑動軸承的早期損壞。
If there are abnormal signs or wear is more than half, be sure to carefully find out the cause, take corresponding measures, the working conditions of the bearing, and pay attention to prevent the early damage of the sliding bearing.
