style="text-indent:25px">為確定軸承壽命的標準，把軸承壽命與可靠性聯(lián)系起來。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，其壽命長短也不相同。若以統(tǒng)計壽命為1單位，較長的相對壽命為4單位，較短的為0.1-0.2單位，至長與至短壽命之比為20-40倍。90%的軸承不產(chǎn)生點蝕，所經(jīng)歷的轉(zhuǎn)數(shù)或小時數(shù)稱為軸承額定壽命。基本額定動載荷：為比較軸承抗點蝕的承載能力，規(guī)定軸承的額定壽命為一百萬轉(zhuǎn)（106）時，所能承受的至大載荷為基本額定動載荷，以C表示。也就是軸承在額定動載荷C作用下，這種軸承工作一百萬轉(zhuǎn)（106）而不發(fā)生點蝕失效的可靠度為90%，C越大承載能力越高。對于基本額定動載荷：

style="text-indent:25px">辨別雙列圓柱滾子設(shè)備軸承的質(zhì)量，我們通常從以下幾個方面進行：表面是否有渾濁的油跡：表面是否有渾濁的油跡這需要我們在購買進口軸承時應該特別注意。由于國內(nèi)的防銹技術(shù)與國外先進制造國還有一定的差距，因此對軸承體進行防銹處理時很容易留下厚厚的油跡，用手接觸時感覺粘粘稠稠的，而國外原裝進口的軸承上幾乎看不到任何防銹油的痕跡。據(jù)業(yè)內(nèi)人士介紹，特別細心的人可以在進口軸承上聞到一種特殊的味道，這就是防銹油的味道。倒角是否均勻：所謂軸承的倒角，也就是橫面與豎面的交接處，仿冒的軸承產(chǎn)品由于生產(chǎn)技術(shù)的限制，在這些邊邊角角的部位處理得不盡人意，這一點我們可以輕松辨別</p><p style="text-indent:25px">為使雙列圓柱軸承充分發(fā)揮并長期保持其應有的性能，必須要切實做好定期維護保養(yǎng)(定期檢查)。通過適當?shù)亩ㄆ跈z查，做到早期發(fā)現(xiàn)故障，防止事故于未然，對提高生產(chǎn)率和經(jīng)濟性十分重要。一般雙列圓柱滾子軸承在出廠時均涂有適量的防銹油并用防銹紙包裝，只要該包裝不被破壞，軸承的質(zhì)量將得到保證。但長期存放時，擬在濕度低于65%、溫度為20℃左右的條件下，存放在高于地面30cm的架子上為宜。另外，保管場所應避開直射陽光或與寒冷的墻壁觸。圓柱滾子軸承需要注意哪些問題？</p><div

style="text-indent:25px">為了確定軸承壽命的標準，需要把軸承壽命與可靠性聯(lián)系起來。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，其壽命長短也不相同。若以統(tǒng)計壽命為1單位，較長的相對壽命為4單位，較短的為0.1-0.2單位，至長與至短壽命之比為20-40倍。90%的軸承不產(chǎn)生點蝕，所經(jīng)歷的轉(zhuǎn)數(shù)或小時數(shù)稱為軸承額定壽命?；绢~定動載荷：為比較軸承抗點蝕的承載能力，規(guī)定軸承的額定壽命為一百萬轉(zhuǎn)（106）時，所能承受的至大載荷為基本額定動載荷，以C表示。也就是軸承在額定動載荷C作用下，這種軸承工作一百萬轉(zhuǎn)（106）而不發(fā)生點蝕失效的可靠度為90%，C越大承載能力越高。對于基本額定動載荷：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。重慶NN3021KTN/W33雙列圓柱滾子系列軸承</p><p
