NN型結(jié)構(gòu):外圈無擋邊，內(nèi)圈有雙擋邊。 NNU型結(jié)構(gòu):內(nèi)圈無擋邊，外圈有雙擋邊。軸可以軸向延伸。 NNU49系列軸承截面比NN30系列小、主軸系的剛性高、承載能打小。內(nèi)孔帶1 : 12錐度的軸承，安裝后可以調(diào)整軸承的同際或子教向。徑向游隙的影響：在使用圓柱滾子軸承時，對徑向游隙進(jìn)行控制非常重要。徑向隙在處于"+” 測時，軸承的剛性壽命會急劇下降，運轉(zhuǎn)中發(fā)熱也會小反之，如果將游隙設(shè)為"-” 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(dá)到定的予載荷。內(nèi)孔帶錐度的圓柱滾子軸承后可以達(dá)到定的預(yù)負(fù)荷。軸承的工作間隱或予載荷取決于轉(zhuǎn)速、負(fù)載、潤滑、剛度、溫及軸承座的精度。</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體呈幾何形狀。經(jīng)改進(jìn)設(shè)計后，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，不僅提高了軸承的軸向承載能力，同時改善了滾子端面與擋邊接觸區(qū)域的潤滑條件，提高了軸承的使用性能。 1．外圈無擋邊N0000型和內(nèi)圈無擋邊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根據(jù)精度等級可分PO,P6，P5,P4，P2.精度等級從低依次到高排序。</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,其承載能力和剛度高于點接觸的角接觸軸承，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的導(dǎo)向性能較差。再者大型機床零件尺寸和質(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)動主軸，同時觀察軸承滾動體的轉(zhuǎn)動情況。無錫哈配機電設(shè)備有限公司致力于為客戶打造生態(tài)化互聯(lián)網(wǎng)平臺，為客戶提供一站式整體解決方案。長沙NN3013K/W33雙列圓柱滾子系列軸承廠家直銷價</p><p
