style="text-indent:25px">角接觸球軸承可同時(shí)承受徑向負(fù)荷和軸向負(fù)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。因其內(nèi)外圈的滾道可在水平軸線上有相對位移，所以可以同時(shí)承受徑向負(fù)荷和軸向負(fù)荷——聯(lián)合負(fù)荷（單列角接觸球軸承只能承受單方向軸向負(fù)荷，因此一般都常采用成對安裝）。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。單列角接觸球軸承只能承受一個(gè)方向的軸向負(fù)荷，在承受徑向負(fù)荷時(shí)，將引起附加軸向力。并且只能限制軸或外殼在一個(gè)方向的軸向位移。若是成對雙聯(lián)安裝，使一對軸承的外圈相對，即寬端面對寬端面，窄端面對窄端面。這樣即可避免引起?附加軸向力，而且可在兩個(gè)方向使軸或外殼限制在軸向游隙范圍內(nèi)。</p><p style="text-indent:25px">軸承轉(zhuǎn)速對軸承摩擦力矩的影響。角接觸球軸承低速旋轉(zhuǎn)時(shí)，軸承摩擦力矩隨著軸承的轉(zhuǎn)速增大而增大，這是因?yàn)榇藭r(shí)鋼球與滾道之間彈流潤滑膜還沒有建立，軸承基本處于干涸潤滑狀態(tài)；當(dāng)軸承轉(zhuǎn)速達(dá)到一定值時(shí)，即鋼球與滾道之間潤滑已經(jīng)形成，軸承摩擦力矩隨著軸承轉(zhuǎn)速的增大而減小，當(dāng)軸承轉(zhuǎn)速繼續(xù)增大，軸承潤滑油膜厚度逐漸增大，油膜引起的摩擦力矩也隨著增大，從而造成軸承摩擦力矩隨著軸承的轉(zhuǎn)速繼續(xù)增大而增大。軸承載荷對軸承摩擦力矩的影響。軸承摩擦力矩隨著軸向力的增加而增大。軸承工作溫度對摩擦力矩的影響。剛開始運(yùn)轉(zhuǎn)時(shí)，隨著軸承工作溫度的升高，潤滑油粘度下降，從而造成軸承摩擦力矩逐漸減??；當(dāng)軸承工作溫度升高到一定值后，軸承摩擦力矩隨著工作溫度的升高而迅速增大。一般的角接觸球軸承使用的是酚醛膠布保持架,這種保持架的材料是較常規(guī)的。</p><div

style="text-indent:25px">精密角接觸球軸承的特點(diǎn)：①具有接觸角,可以承受單向的軸向負(fù)荷或者是合成負(fù)荷。②將二個(gè)以上組合后，加上預(yù)負(fù)荷來使用。選擇精密角接觸球軸承時(shí)，考慮上述2項(xiàng)非常重要。因?yàn)椴煌奶攸c(diǎn)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比較適當(dāng)?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。角接觸球軸承是軸承類型中常見的一種之一。南京71913CETA-2RZ角接觸球軸承</p><p style="text-indent:25px">保持架磨損帶來的油脂的劣化少，普遍適用于機(jī)床主軸軸承等保持架。71921CTA/HQ1角接觸球軸承</p><p style="text-indent:25px">角接觸球軸承精度等級包括尺寸公差和旋轉(zhuǎn)精度。精度由低到高表示為P0(普通)、P6(P6X)、P5、P4、P2。此外，歐美品牌中也用P3、P7、P9表示精度等級，P3相當(dāng)于ISO和JIS標(biāo)準(zhǔn)的P6級， P7相當(dāng)于P4級，P9相當(dāng)于P2級。角接觸球軸承有：7000C型(∝=15°)、 7000AC型(∝=25°) 和7000B(∝=40°)幾種類型。該種軸承的鎖口在外圈上，一般內(nèi)外圈不能分離，可承受徑向和軸向的聯(lián)合載荷以及一個(gè)方向的軸向載荷。承受軸向載荷的能力由接觸角決定，接觸角越大，則承受軸向載荷的能力高。該種軸承能限制軸或外殼在一個(gè)方向的軸向位移。71921CTA/HQ1角接觸球軸承</p><p
