style="text-indent:25px">雙列圓柱滾子軸承使用時(shí)有哪些需要注意的地方呢？從使用角度看，保證雙列圓柱滾子軸承能可靠地工作要注意以下幾點(diǎn)：1、改善潤滑質(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，過小則潤滑不良，可能燒瓦。麗水NN3022/W33雙列圓柱滾子系列軸承高精度圓柱滾子軸承主要用于機(jī)床、軋機(jī)架、塑料滾筒、磨床以及大型齒輪箱。</p><div

style="text-indent:25px">圓錐孔雙列圓柱滾子軸承屬于線性接觸軸承,它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。在內(nèi)圈和外圈的某一側(cè)有雙擋邊，另一側(cè)的套圈有單個(gè)擋邊的圓柱滾子軸承。麗水NN3022/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：該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，利用過盈配合減小軸承游隙，或者達(dá)到預(yù)緊的目的。對內(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。麗水NN3022/W33雙列圓柱滾子系列軸承</p><p
