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。</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。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將雙列圓柱滾子軸承拆下檢查時(shí)，先用攝影等方法做好外觀記錄。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

style="text-indent:25px">圓錐孔雙列圓柱滾子軸承屬于線性接觸軸承,其承載能力和剛度高于點(diǎn)接觸的角接觸軸承，常用于載荷較大、要求剛度較高，而轉(zhuǎn)速相對(duì)來說不很高的中、大、重型機(jī)床主軸系統(tǒng)中。雙列圓柱滾子軸承直徑與寬度之比一般在4~7之間，由于雙列圓柱滾子軸承的徑寬比較大，導(dǎo)致在主軸箱孔中和主軸上安裝時(shí)的導(dǎo)向性能較差。再者大型機(jī)床零件尺寸和質(zhì)量較大，給裝配工作帶來一定的難度，容易造成安裝軸承時(shí)的力量不均勻。以上的種種原因，導(dǎo)致主軸軸承的內(nèi)外圈安裝位置偏移,軸承滾動(dòng)體與軸承的內(nèi)外圈接觸不良，致使主軸剛度和回轉(zhuǎn)精度降低。檢驗(yàn)主軸軸承的內(nèi)外圈安裝端正的方法如下:在預(yù)緊軸承內(nèi)圈的過程中，不斷的轉(zhuǎn)動(dòng)主軸，同時(shí)觀察軸承滾動(dòng)體的轉(zhuǎn)動(dòng)情況。雙列圓柱滾子軸承有NN和NNU兩種結(jié)構(gòu)，直徑系列分別為30系列和49系列。81122雙列圓柱滾子系列軸承市面價(jià)</p><p
