style="text-indent:25px">軸承的徑向游隙又分為原始游隙、安裝游隙和工作游隙。通常，軸承的原始徑向游隙大于軸承工作時(shí)的游隙。游隙是軸承的一個(gè)重要技術(shù)參數(shù)，它直接影響到軸承的載荷分布、振動(dòng)、噪聲、摩擦、使用壽命和機(jī)械的運(yùn)動(dòng)精度等技術(shù)性能。嚴(yán)格來(lái)說(shuō)，軸承的額定動(dòng)載荷是隨游隙的大小而變化的。產(chǎn)品樣本中所列的額定載荷(C和C0)是工作游隙為零時(shí)的載荷數(shù)值。游隙過(guò)大，會(huì)引起軸承內(nèi)部承載區(qū)域減小，滾動(dòng)接觸面應(yīng)力增大，軸承的運(yùn)動(dòng)精度下降，振動(dòng)和噪聲增大，軸承的使用壽命縮短：如游隙過(guò)小，會(huì)引起發(fā)熱升溫，甚至?xí)?dǎo)致軸承在運(yùn)轉(zhuǎn)中發(fā)生“咬死”的現(xiàn)象。因此，根據(jù)軸承的類型及工作條件選擇不同等級(jí)的軸承游隙是很重要的。滾動(dòng)軸承的裝配工作開(kāi)始之前，首先需要對(duì)滾動(dòng)軸承進(jìn)行清洗，保持其干凈整潔。天津調(diào)心球軸承生產(chǎn)廠家</p><p
