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，作為當(dāng)代機(jī)械重要零件，應(yīng)用普遍。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)體和保持架之間不僅發(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。81111雙列圓柱滾子系列軸承哪家好圓柱滾子與滾道呈線接觸，徑向載荷能力大。</p><div style="width:100%;text-align:

style="text-indent:25px">為確定軸承壽命的標(biāo)準(zhǔn)，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。基本額定動(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：

style="text-indent:25px">機(jī)床主軸常用軸承有五大類：深溝球軸承，角接觸球軸承，雙向推力角接觸球軸承，雙列圓柱滾子軸承，圓錐滾子軸承。雙列圓柱滾子軸承這類軸承能承受較大的徑向載荷并允許有較高的轉(zhuǎn)速。軸承中的兩列滾子以交叉方式排列，旋轉(zhuǎn)時(shí)波動(dòng)頻率可比單列軸承提高一倍，振幅降低70％。常用的此類軸承有兩種形式：NN30/W33、NN30K/W33兩個(gè)系列軸承內(nèi)圈帶擋邊，外圈可分離；NNU49/W33、NNU49K/W33兩個(gè)系列軸承外圈帶擋邊，內(nèi)圈可分離，其中NN30K/W33和NNU49K/W33系列內(nèi)圈為錐孔（錐度1：12），與主軸的錐形軸頸相配合，軸向移動(dòng)內(nèi)圈，可使內(nèi)圈脹大，以減小軸承游隙甚至預(yù)緊軸承。圓柱孔軸承通常采用熱裝，利用過(guò)盈配合減小軸承游隙，或者達(dá)到預(yù)緊的目的。對(duì)內(nèi)圈可分離的NNU49系列軸承，一般在內(nèi)圈裝上主軸后再作滾道的精加工，以獲得高的主軸旋轉(zhuǎn)精度。雙列圓柱滾子軸承軸承具有結(jié)構(gòu)緊湊、剛性大、承載能力大、受負(fù)荷后變形小等優(yōu)點(diǎn)。</p><div
