style="text-indent:25px">軸承溫度過(guò)高：在機(jī)構(gòu)運(yùn)轉(zhuǎn)時(shí)，安裝軸承的部位允許有一定的溫度，當(dāng)用手撫摸機(jī)構(gòu)外殼時(shí)，應(yīng)以不感覺(jué)燙手為正常，反之則表明軸承溫度過(guò)高。軸承溫度過(guò)高的原因有：潤(rùn)滑油質(zhì)量不符合要求或變質(zhì)，潤(rùn)滑油粘度過(guò)高；機(jī)構(gòu)裝配過(guò)緊（間隙不足）；軸承裝配過(guò)緊；軸承座圈在軸上或殼內(nèi)轉(zhuǎn)動(dòng)；負(fù)荷過(guò)大；軸承保持架或滾動(dòng)體碎裂等。軸承磨損：滾動(dòng)軸承磨損是軸使用過(guò)程中常見(jiàn)的設(shè)備問(wèn)題，主要是由軸的金屬特性造成的：金屬雖然硬度高，但是退讓性差（變形后無(wú)法復(fù)原）、抗沖擊性能差、抗疲勞性能差，因此容易造成粘著磨損、磨料磨損、疲勞磨損、微動(dòng)磨損等。大部分的軸類磨損不易察覺(jué)，只有出現(xiàn)機(jī)器高溫、跳動(dòng)幅度大、異響等情況時(shí)，才會(huì)引起察覺(jué)，但是到人們發(fā)覺(jué)時(shí)，大部分滾動(dòng)軸都已磨損，從而造成機(jī)器停機(jī)。角接觸球軸承生產(chǎn)廠家</p><p
