style="text-indent:25px">為了確定軸承壽命的標(biāo)準(zhǔn)，需要把軸承壽命與可靠性聯(lián)系起來(lái)。雙列圓柱滾子額定壽命：由于制造精度，材料均勻程度的差異，即使是同樣材料，同樣尺寸的同一批軸承，在同樣的工作條件下使用，其壽命長(zhǎng)短也不相同。若以統(tǒng)計(jì)壽命為1單位，較長(zhǎng)的相對(duì)壽命為4單位，較短的為0.1-0.2單位，至長(zhǎng)與至短壽命之比為20-40倍。90%的軸承不產(chǎn)生點(diǎn)蝕，所經(jīng)歷的轉(zhuǎn)數(shù)或小時(shí)數(shù)稱為軸承額定壽命?；绢~定動(dòng)載荷：為比較軸承抗點(diǎn)蝕的承載能力，規(guī)定軸承的額定壽命為一百萬(wàn)轉(zhuǎn)（106）時(shí)，所能承受的至大載荷為基本額定動(dòng)載荷，以C表示。也就是軸承在額定動(dòng)載荷C作用下，這種軸承工作一百萬(wàn)轉(zhuǎn)（106）而不發(fā)生點(diǎn)蝕失效的可靠度為90%，C越大承載能力越高。對(duì)于基本額定動(dòng)載荷：1．向心軸承是指純徑向載荷2．推力球軸承是指純軸向載荷3．向心推力軸承是指產(chǎn)生純徑向位移得徑向分量。</p><p style="text-indent:25px">軸承是用來(lái)支撐的部件，也是用來(lái)支承軸上回轉(zhuǎn)的零件，軸承作為當(dāng)代機(jī)械重要零件，應(yīng)用較為普遍。雙列圓柱滾子軸承是軸承的其中一種。下面，我們就來(lái)介紹下軸承常見(jiàn)的幾種性能：1.耐磨性能：軸承工作時(shí)，套圈、滾動(dòng)體和保持架之間不只發(fā)生滾動(dòng)摩擦，而且也會(huì)發(fā)生滑動(dòng)摩擦，從而使軸承零件不斷地磨損。為了減少軸承零件的磨損，保持軸承精度穩(wěn)定性，延長(zhǎng)使用壽命，軸承應(yīng)有很好的耐磨性能。2.接觸疲勞強(qiáng)度：軸承在周期負(fù)荷的作用下，接觸表面很容易發(fā)生疲勞破壞，即出現(xiàn)龜裂剝落，這是軸承的主要損壞形式。因此，為了提高軸承的使用壽命，軸承必須具有很高的接觸疲勞強(qiáng)度。雙列圓柱滾子軸承的潤(rùn)滑分為：脂潤(rùn)滑和油潤(rùn)滑。</p><div
