style="text-indent:25px">角接觸球軸承可以同時承受徑向負荷和軸向負荷。能在較高的轉(zhuǎn)速下工作。接觸角越大，軸向承載能力越高。接觸角為徑向平面內(nèi)球和滾道的接觸點連線與軸承軸線的垂直線間的角度。高精度和高速軸承通常取15度接觸角。在軸向力作用下，接觸角會增大。角接觸球軸承的內(nèi)、外圈上都有滾道，而且內(nèi)、外圈能沿軸承軸向作相對位移。這類軸承特別適用于承受復合負荷，即徑向和軸向同時作用的負荷。角接觸球軸承軸向負荷承受能力隨接觸角α的增大而增大。接觸角為徑向平面內(nèi)球和滾道的接觸點連線與軸承軸線的垂直線間的角度。</p><p style="text-indent:25px">背對背（兩軸承的寬端面相對）安裝時，軸承的接觸角線沿回轉(zhuǎn)軸線方向擴散，可以增加其徑向和軸向的支承角度剛性，抗變形能力提高；面對面（兩軸承的窄端面相對）安裝時，軸承的接觸角線朝回轉(zhuǎn)軸線方向收斂，其支承角度剛性較小。由于軸承的內(nèi)圈伸出外圈，當兩軸承的外圈壓緊到一起時，外圈的原始間隙消除，可以增加軸承的預加載荷；串聯(lián)排列（兩軸承的寬端面在一個方向）安裝時，軸承的接觸角線同向且平行，可使兩軸承分擔同一方向的工作載荷。但使用這種安裝形式時，為了保證安裝的軸向穩(wěn)定性，兩對串聯(lián)排列的軸承必須在軸的兩端對置安裝。角接觸球軸承在軸向力作用下，接觸角會增大。</p><div

style="text-indent:25px">推力球軸承承受軸向力的能力比角接觸球軸承大很多(約為兩倍)。推力角接觸球的軸承精度要比推力球軸承的精度高很多，可承受的轉(zhuǎn)速也高很多，可以作為主軸軸承使用。雙向推力角接觸球軸承：通常選用230000型雙向推力角接觸球軸承，接觸角為60°，由一個帶潤滑油孔的座圈、兩個軸圈、一個隔圈和兩組鋼球與保持架組件構(gòu)成。選擇合適的隔圈高度可以使軸承裝配后具有所需的預載荷。該類軸承可承受雙向軸向載荷,具有良好的剛性,正常潤滑時溫升低，轉(zhuǎn)速高，并且易于裝拆，作為一種新結(jié)構(gòu)，目前多用于磨床、車床、鏜床、銑床、鉆床等主軸上，使用中常與雙列圓柱滾子軸承組配。使用上向心推力球軸承和推力球軸承一樣不能承受徑向力，而角接觸球軸承可以同時承受徑向力和軸向力。角接觸球軸承安裝時，不得用鎯頭等工具直接敲擊角接觸球軸承端面，以免損傷角接觸球軸承。71900ACETA-2RZ/HQ1角接觸球軸承</p><p

style="text-indent:25px">精密角接觸球軸承突出的特點是：①具有接觸角，可以承受單向的軸向負荷或者是合成負荷。②將二個以上組合后，加上預負荷來使用。選擇精密角接觸球軸承時，考慮上述2項非常重要，因為不同的特點的組合性能不同，所以要充分理解并根據(jù)軸承的具體用途目的來選擇適當?shù)妮S承。精密角接觸球軸承有719、70和72系列三種直徑系列，接觸角為15°(后綴為C)和25°(后綴為AC)。接觸角大的用于軸向剛性高、軸向承載能力大的場合。高速、超高速軸承(如:電主軸軸承)后綴為CETA(15*)和ACETA(25*)。這些軸承的鋼球數(shù)量較多，有足夠的剛性和承載能力。71819ACTA角接觸球軸承</p></p><br
