style="text-indent:25px">角接觸球軸承在負(fù)荷作用下，會自然形成接觸角，可同時承受徑向負(fù)荷和單向軸向負(fù)荷，承受負(fù)荷能力隨接觸角的大小而改變，接觸角越大，承受軸向負(fù)荷能力也大，接觸角分為15°、30°、40°。另外，增加了鋼球粒數(shù)，以獲得更好的軸承強度，同時將內(nèi)圈或外圈的一個擋邊加工成斜坡形式，分離式不要鎖量，非分離式就要設(shè)計一定鎖量，以確保不散套，這種軸承常用在高速運轉(zhuǎn)場所。為了平衡軸向力，經(jīng)常采用配對安裝，故又有面對面、背對背及同方向三種形式，隨著科技進(jìn)步和軸承工作條件的不同，角接觸球軸承具有多種結(jié)構(gòu)形式。</p><p

style="text-indent:25px">雙列角接觸球軸承主要用于限制軸和外殼雙向軸向位移的部件中雙列角接觸球軸承內(nèi)、外圈之間的可傾斜性有限，允許傾斜角取決于軸承的內(nèi)部間隙、軸承尺寸、內(nèi)部設(shè)計及作用于軸承上的力和力矩，而至大允許傾斜角應(yīng)保證軸承內(nèi)不會產(chǎn)生過高的附加應(yīng)力。若軸承內(nèi)、外圈之間存在傾斜角，將影響軸承的壽命，同時造成軸承運轉(zhuǎn)精度下降，運轉(zhuǎn)噪聲增大。雙列角接觸球軸承一般采用尼龍保持架或黃銅實體保持架。雙列角接觸球軸承安裝時應(yīng)注意，雖然軸承可承受雙向軸向載荷，但若一側(cè)有裝球缺口時，則應(yīng)注意不要讓主要軸向載荷通過有缺口的一側(cè)溝邊。在軸承使用時應(yīng)注意使不帶裝球缺口的一側(cè)滾道承受主要載荷。定位預(yù)緊：沿著施力方向加上預(yù)緊力，讓間隙為0。7017BTN角接觸球軸承哪家比較好</p><p
