style="text-indent:25px">索倫軸承（外圈帶止動槽的雙列圓柱滾子軸承）兩側(cè)裝有聚亞安脂（AU）制成的接觸式密封圈，可以提供良好的密封效果。軸承內(nèi)裝填有鋰基潤滑脂，可在-40至+80℃溫度之間使用。這種帶密封的軸承，在一定的條件下，是無需維護的。但在潮濕或污染較嚴重的環(huán)境下，或在中速至高速下運行時，軸承就必須定時做補充潤滑，可以使用內(nèi)圈或外圈上的潤滑孔進行潤滑。還可以將密封圈從軸承中取出，軸承就可以作為開式軸承來使用。這類軸承的剛性非常好，可承受很高的徑向力和中等大小的雙向軸向力。徐州NN3012KTN/W33雙列圓柱滾子系列軸承商家圓柱滾子軸承需要注意哪些問題？</p><div

剛性會增加，但壽命會急劇下降。內(nèi)部間隙或予載荷為使機床主軸系統(tǒng)獲得較高的旋轉(zhuǎn)精度及剛度，軸承的徑向溯較小或軸承安裝后達到定的予載荷。內(nèi)孔帶錐度的圓柱滾子軸承后可以達到定的預(yù)負荷。軸承的工作間隱或予載荷取決于轉(zhuǎn)速、負載、潤滑、剛度、溫及軸承座的精度。</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，軸承作為當代機械重要零件，應(yīng)用較為普遍。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。雙列圓柱滾子軸承的安裝是否正確，影響著精度、壽命、性能。</p><div

style="text-indent:25px">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)。該類軸承具有結(jié)構(gòu)緊湊、剛性大、承載能力大、受負荷后變形小等優(yōu)點，特別適用于機床主軸支承。圓錐形內(nèi)孔還可以起到微量調(diào)整游隙的作用，且可以簡化定位裝置結(jié)構(gòu)，方便安裝拆卸。常用的雙列圓柱滾子軸承有以下下幾種形式：NN、NNU型。 NN型軸承的外圈無擋邊，內(nèi)圈兩側(cè)有擋邊中間有中擋邊。可以允許軸相對軸承座之間在軸向產(chǎn)生兩個方向的位移。
