斗式提升機(jī)在使用的過(guò)程中如果使用不當(dāng)就會(huì)造成軸承的損壞，下面就斗式提升機(jī)使用時(shí)軸承注意要點(diǎn)講解一下，希望使用的時(shí)候能夠引起注意。
(1)安裝不當(dāng)
所有過(guò)早失效的軸承中約有16%是由安裝不當(dāng)和未意識(shí)到采用正確的安裝工具所引起的，要進(jìn)行正確和有效的安裝與拆卸，不同的安裝可能需要使用機(jī)械的、液壓的或加熱的方法，基于其專(zhuān)業(yè)的工程服務(wù)技術(shù)知識(shí)。
(2)潤(rùn)滑不當(dāng)
雖然在使用“免維護(hù)”軸承的地方不需要考慮這一問(wèn)題，但是在過(guò)早失效的軸承中，仍然有36%是由于使用潤(rùn)滑劑的技術(shù)參數(shù)不正確或不足以滿(mǎn)足應(yīng)用上的要求所引起的。不可避免的結(jié)果是：缺少正確潤(rùn)滑的軸承將會(huì)遠(yuǎn)在預(yù)期使用壽命到來(lái)之前就失效。由于軸承通常是機(jī)器中最不易接近的部件，忽略潤(rùn)滑經(jīng)常會(huì)導(dǎo)致各種問(wèn)題。
(3)污染
軸承可以說(shuō)是精密部件，如果軸承和潤(rùn)滑劑不能遠(yuǎn)離污染物，那么軸承無(wú)法有效地運(yùn)行。而且，由于預(yù)裝潤(rùn)滑脂的永久性密封軸承只占全部軸承的很小一部分，在所有過(guò)早失效的軸承中至少有14%要?dú)w因于污染問(wèn)題。由于在斗式提升機(jī)使用的過(guò)程中，裝載物料運(yùn)行，物料不可避免的會(huì)出現(xiàn)灑落的情況，物料就有可能沾粘在軸承的潤(rùn)滑油上，造成潤(rùn)滑油變稠，造成軸承抱死，發(fā)熱等情況，直至軸承損壞。

Bucket elevator in the use process if used improperly will cause bearing damage, the bucket elevator when the bearing points explain, hope to use it to attract attention.
(1) improper installation
All the premature failure of the bearing is about 16% by improper installation and not aware of the correct installation tool is caused, to correct and effective installation and disassembly, different installation may require the use of mechanical, hydraulic or heating method, based on its professional engineering services and technical knowledge.
(2) improper lubrication
Although the use of" maintenance-free" bearing place does not need to consider this problem, but in the premature failure of the bearing, there are still36% is due to the use of lubricants technical parameters are incorrect or insufficient to meet application requirements arising from the. The inevitable result is : the lack of correct lubricated bearing will be expected service life before the arrival of the lapse. Because the bearing usually machine most inaccessible parts, ignoring the lubrication can often lead to various problems.
(3) pollution
The bearing can be said to be precise parts, if the bearings and lubricants can't stay away from pollution, so the bearing can not run effectively. But, because preloads grease permanently sealed bearing only a small fraction of the total bearing, in all the premature failure of the bearing has at least14% attributed to the pollution problem. The bucket type lifting machine used in the process of running, loading materials, the material will inevitably be spilled, material is likely to stick in the bearing lubricating oil, lubricating oil from thickening, resulting in bearing lock, fever and so on, until the bearing damage.
