style="text-indent:25px">機(jī)床主軸常用軸承有五大類：深溝球軸承，角接觸球軸承，雙向推力角接觸球軸承，雙列圓柱滾子軸承，圓錐滾子軸承。雙列圓柱滾子軸承這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(duì)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。</p><p style="text-indent:25px">圓柱滾子與滾道呈線接觸，徑向載荷能力大。既適用于承受重載荷與沖擊載荷，也適用于高速旋轉(zhuǎn)。圓柱滾子軸承滾道及滾動(dòng)體呈幾何形狀。經(jīng)改進(jìn)設(shè)計(jì)后，具有較高的承載能力，擋邊和滾子端面的新型結(jié)構(gòu)設(shè)計(jì)，不僅提高了軸承的軸向承載能力，同時(shí)改善了滾子端面與擋邊接觸區(qū)域的潤(rùn)滑條件，提高了軸承的使用性能。 1．外圈無(wú)擋邊N0000型和內(nèi)圈無(wú)擋邊NU0000型，圓柱滾子軸承此種軸承可接受較大的徑向載荷,極限轉(zhuǎn)速高,不束縛軸或外殼的軸向位移,不能接受軸向載荷。 2．內(nèi)、外圈均帶擋邊的圓柱滾子軸承NJ0000型、NF0000型軸承可束縛軸或外殼一個(gè)方向的軸向位移,并能接受較小的單向軸向載荷。NU0000+HJ0000型、NJ0000+HJ0000型、NUP0000型軸承，可在進(jìn)口軸承的軸向間隙領(lǐng)域內(nèi)束縛軸或外殼兩個(gè)方向的軸向位移，并能接受較小的雙向軸向載荷圓柱滾子軸承此種軸承可接受較大的徑向載荷,極限轉(zhuǎn)速高。</p><div

style="text-indent:25px">軸承是用來(lái)支撐的部件，也是用來(lái)支承軸上回轉(zhuǎn)的零件，軸承作為當(dāng)代機(jī)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(lái)介紹下軸承常見的幾種性能：1.調(diào)心性能：軸中心線相對(duì)軸承座孔中心線傾斜時(shí)，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(rùn)滑、改善冷卻條件等，都可以提高極限轉(zhuǎn)速。2.潤(rùn)滑性能：軸承的潤(rùn)滑目有減少軸承內(nèi)部摩擦及磨損，防止燒粘；延長(zhǎng)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灰灿蟹乐巩愇锴秩胼S承內(nèi)部，或防止生銹、腐蝕之效果。C1一直以來(lái)較為被采用游隙。濟(jì)南常見雙列圓柱滾子系列軸承</p><p style="text-indent:25px">圓柱滾子軸承特點(diǎn)：可作自由端支承使用。昆明NN3007KTN雙列圓柱滾子系列軸承</p><p 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(hào)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(fù)荷后變形小等優(yōu)點(diǎn)，特別適用于機(jī)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(jiǎn)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(wú)擋邊，內(nèi)圈兩側(cè)有擋邊中間有中擋邊。可以允許軸相對(duì)軸承座之間在軸向產(chǎn)生兩個(gè)方向的位移。
