b、粗洗時，在油中用刷子等清掃潤滑脂或粘著物。此時若在油中轉(zhuǎn)動軸承，注意會因異物等損傷滾動面。 c、精洗時，在油中慢慢轉(zhuǎn)動軸承，須仔細地進行。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。重慶通用NNU4922KTN/W33雙列圓柱滾子系列軸承雙列圓柱滾子軸承有圓柱形內(nèi)孔和圓錐形內(nèi)孔（軸承后置代號加K）兩種結(jié)構(gòu)。</p><div

a、軸承的清洗分粗洗和精洗進行，并可在使用的容器底部放上金屬網(wǎng)架。 b、粗洗時，在油中用刷子等清掃潤滑脂或粘著物。此時若在油中轉(zhuǎn)動軸承，注意會因異物等損傷滾動面。 c、精洗時，在油中慢慢轉(zhuǎn)動軸承，須仔細地進行。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。</p><p 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行判斷。判斷的標(biāo)準(zhǔn)根據(jù)機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) 滾道面物滾動面的剝離。滾動體是圓柱滾子的向心滾動軸承。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="重慶通用NNU4922KTN/W33雙列圓柱滾子系列軸承,雙列圓柱滾子系列軸承"

style="text-indent:25px">雙列圓柱滾子軸承的拆卸是定期維修，軸承更換時進行。拆卸后，如果繼續(xù)使用，或還需要檢查軸承之狀態(tài)時，其拆卸也要與安裝時同樣仔細進行。注意不損傷軸承各零件，特別是過盈配合軸承的拆卸，操作難度大。根據(jù)需要設(shè)計制作拆卸工具也十分重要。在拆卸時，根據(jù)圖紙研究拆卸方法、順序、調(diào)查軸承的配合條件，以求得拆卸作業(yè)的萬無一失。外圈的拆卸過盈配合的外圈，事先在外殼的圓周上設(shè)置幾處外圈擠壓螺桿用螺絲，一面均等地擰緊螺桿，一邊拆卸。這些螺桿孔平常蓋上盲塞，圓錐滾子軸承等的分離型軸承，在外殼擋住肩上設(shè)置出幾處切口，使用墊塊，用壓力機拆卸，或輕輕敲打著拆卸。雙列圓柱滾子軸承的潤滑分為脂潤滑和油潤滑。長春雙列圓柱滾子系列軸承</p><p

style="text-indent:25px">軸承是用來支撐的部件，也是用來支承軸上回轉(zhuǎn)的零件，作為當(dāng)代機械重要零件，應(yīng)用普遍。雙列圓柱滾子軸承是軸承的其中一種。下面，我們就來介紹下軸承常見的幾種性能： 1. 調(diào)心性能：軸中心線相對軸承座孔中心線傾斜時，軸承仍能正常工作。雙列向心球面球軸承和雙列向心球面滾子軸承具有良好的調(diào)心性能。滾軸承工作轉(zhuǎn)速應(yīng)低于極限轉(zhuǎn)速。選用高精度軸承、改善保持架結(jié)構(gòu)和材料、采用油霧潤滑、改善冷卻條件等，都可以提高極限轉(zhuǎn)速。 2. 潤滑性能：軸承的潤滑目有減少軸承內(nèi)部摩擦及磨損，防止燒粘；延長其使用壽命；排出摩擦熱、冷卻，防止軸承過熱，防止?jié)櫥妥陨砝匣?；也有防止異物侵入軸承內(nèi)部，或防止生銹、腐蝕之效果。重慶通用NNU4922KTN/W33雙列圓柱滾子系列軸承</p><p
