style="text-indent:25px">圓柱滾子軸承可應(yīng)用于大中型電動(dòng)機(jī)、機(jī)車車輛、機(jī)床主軸、內(nèi)燃機(jī)、發(fā)電機(jī)、燃?xì)鉁u輪機(jī)、減速箱、軋鋼機(jī)、振動(dòng)篩以及起重運(yùn)輸機(jī)械等。圓柱滾子軸承需要注意哪些問(wèn)題？震動(dòng)方面：在平時(shí)的使用中，震動(dòng)對(duì)軸承的損傷是相當(dāng)敏感的，剝落、壓痕、銹蝕、裂紋、磨損等都會(huì)在軸承振動(dòng)測(cè)量中反映出來(lái)。所以，通過(guò)采用特殊的軸承振動(dòng)測(cè)量器(頻率分析器等)可測(cè)量出振動(dòng)的大小，通過(guò)頻率分布可推斷出異常的具體情況。測(cè)得的數(shù)值因軸承的使用條件或傳感器安裝位置等而不同，因此需要事先對(duì)每臺(tái)機(jī)器的測(cè)量值進(jìn)行分析比較后確定判斷標(biāo)準(zhǔn)。溫度方面：高溫經(jīng)常表示圓柱滾子軸承已處于異常情況。高溫也有害于軸承的潤(rùn)滑劑。有時(shí)軸承過(guò)熱可歸諸于軸承的潤(rùn)滑劑。若軸承在超過(guò)125℃的溫度長(zhǎng)期連轉(zhuǎn)會(huì)降低軸承壽命。引起高溫軸承的原因包括：潤(rùn)滑不足或者潤(rùn)滑過(guò)多，軸承滾道中含有雜質(zhì)，極限轉(zhuǎn)速過(guò)高，軸承長(zhǎng)期超負(fù)荷運(yùn)轉(zhuǎn)等。</p><p 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">為了判斷拆下的圓柱滾子軸承能否重新使用，要著重檢查其尺寸精度、旋轉(zhuǎn)精度、內(nèi)部游隙以及配合面、滾道面、保持架和密封圈等。大型軸承因不能用手旋轉(zhuǎn)，注意檢查滾動(dòng)體、滾道面、保持架、擋邊面等外觀，軸承的重要性愈高愈須慎重檢查。關(guān)于檢查結(jié)果，可由用慣軸承或精通軸承者進(jìn)行判斷。判斷的標(biāo)準(zhǔn)根據(jù)機(jī)械性能和重要度以及檢查周期等而有所不同。如有以下?lián)p傷，軸承不得重新使用，必須更換。 1) 軸承零部件的斷裂和缺陷。 2) 滾道面物滾動(dòng)面的剝離。圓錐孔雙列圓柱滾子軸承屬于線性接觸軸承。蘇州NNU4921KTN/W33雙列圓柱滾子系列軸承機(jī)械</p><p style="text-indent:25px">圓柱滾子軸承滾動(dòng)體與套圈擋邊摩擦小，適于高速旋轉(zhuǎn)。湖州NNU4920/W33雙列圓柱滾子系列軸承</p><p style="text-indent:25px">雙列圓柱滾子軸承的密封可分為自帶密封和外加密封兩類。所謂軸承自帶密封就是把軸承本身制造成具有密封性能裝置的。如軸承帶防塵蓋、密封圈等。這種密封占用空間很小，安裝拆卸方便，造價(jià)也比較低。所謂軸承外加密封性能裝置，就是在安裝端蓋等內(nèi)部制造成具有各種性能的密封裝置。對(duì)軸承外加密封的選擇應(yīng)考慮下列幾種主要因素： 1．軸承潤(rùn)滑劑和種類（潤(rùn)滑脂和潤(rùn)滑油）； 2．軸承的工作環(huán)境，占用空間的大??； 3．軸的支承結(jié)構(gòu)優(yōu)點(diǎn)，允許角度偏差； 4．密封表面的圓周速度； 5．軸承的工作溫度； 6.制造成本。根據(jù)軸承工作狀況和工作環(huán)境對(duì)密封程度的要求，在工程設(shè)計(jì)上常常是綜合運(yùn)用各種密封形式，以達(dá)到更好的密封效果。湖州NNU4920/W33雙列圓柱滾子系列軸承</p><p
