1、改善潤(rùn)滑質(zhì)量，控制機(jī)油的壓力、溫度及流量，加強(qiáng)機(jī)油濾清。 2、采用符合規(guī)定的燃油及潤(rùn)滑油。 3、控制柴油發(fā)電機(jī)組的溫度狀態(tài)，在過冷過熱的情況下工作都是不利的。冷天，柴油機(jī)起動(dòng)前應(yīng)先預(yù)熱，并用手轉(zhuǎn)動(dòng)曲軸使機(jī)油進(jìn)入磨擦表面。 4、軸承及軸頸表面質(zhì)量和幾何形狀應(yīng)嚴(yán)格得到保證。 5、軸承間隙要適當(dāng)，發(fā)電機(jī)組過大產(chǎn)生沖擊，過小則潤(rùn)滑不良，可能燒瓦。常州81122雙列圓柱滾子系列軸承機(jī)械高精度圓柱滾子軸承可應(yīng)用于機(jī)床主軸或徑向負(fù)荷較重、剛性要求較高的主軸上。</p><div style="width:100%;text-align: center;"><img

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。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">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。所以，通過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)軸承過熱可歸諸于軸承的潤(rùn)滑劑。若軸承在超過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)滑過多，軸承滾道中含有雜質(zhì)，極限轉(zhuǎn)速過高，軸承長(zhǎng)期超負(fù)荷運(yùn)轉(zhuǎn)等。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)。</p><div

b、粗洗時(shí)，在油中用刷子等清掃潤(rùn)滑脂或粘著物。此時(shí)若在油中轉(zhuǎn)動(dòng)軸承，注意會(huì)因異物等損傷滾動(dòng)面。 c、精洗時(shí)，在油中慢慢轉(zhuǎn)動(dòng)軸承，須仔細(xì)地進(jìn)行。通常使用的清洗劑為中性不含水柴油或煤油，根據(jù)需要有時(shí)也使用溫性堿液等。不論用哪種清洗劑，都要經(jīng)常過濾保持清潔。清洗后，立即在軸承上涂布防銹油或防銹脂。滾動(dòng)體是圓柱滾子的向心滾動(dòng)軸承。常州81122雙列圓柱滾子系列軸承機(jī)械</p><p
