style="text-indent:25px">滾動(dòng)軸承是機(jī)械行業(yè)中較普通、應(yīng)用較廣的零部件，在機(jī)械設(shè)備中起著至關(guān)重要的作用。工程實(shí)際中，滾動(dòng)軸承由于發(fā)熱而引起的失效嚴(yán)重影響設(shè)備的正常工作。因此，對(duì)軸承的溫度場(chǎng)研究至關(guān)重要。角接觸球軸承(Angular Contact Ball Bearings)可同時(shí)承受徑向、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。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(huì)增大。單列角接觸球軸承只能承受一個(gè)方向的軸向載荷，在承受徑向載荷時(shí)，會(huì)引起附加軸向力，必須施向相應(yīng)的反向載荷，因此，該種軸承一般都成對(duì)使用。</p><p style="text-indent:25px">角接觸球軸承通過非對(duì)稱座圈支撐徑向和軸向載荷，該不對(duì)稱座圈在一定角度內(nèi)容納軸承的球形滾動(dòng)元件，也稱為軸承滾珠。軸承與其軸線之間的角度越深，軸承承受的軸向載荷就越大。因?yàn)檩S向載荷與徑向載荷成反比，所以軸向載荷越大意味著徑向載荷越小。角接觸球軸承采用單列和雙列配置，具體取決于其承載的負(fù)載方向。單列角接觸球軸承*支持一個(gè)方向的軸向載荷，而雙列角接觸球軸承支持兩個(gè)方向的軸向載荷。角接觸軸承能夠做到與徑向類軸承相同的精度公差，但設(shè)計(jì)的接觸角為15度，30度和40度，以適應(yīng)更大的推力載荷。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。</p><div

style="text-indent:25px">角接觸球軸承的安裝比深溝球軸承復(fù)雜，多為成對(duì)安裝，并需采用預(yù)加載荷。安裝得好，可使主機(jī)的工作精度、軸承壽命有效提高；否則，不*精度達(dá)不到要求，壽命也會(huì)受到影響。角接觸球軸承的安裝形式，有背對(duì)背、面對(duì)面和串聯(lián)排列三種。背對(duì)背（兩軸承的寬端面相對(duì)）安裝時(shí)，軸承的接觸角線沿回轉(zhuǎn)軸線方向擴(kuò)散，可增加其徑向和軸向的支承角度剛性，抗變形能力至大；面對(duì)面（兩軸承的窄端面相對(duì)）安裝時(shí)，軸承的接觸角線朝回轉(zhuǎn)軸線方向收斂，其地承角度剛性較小。由于軸承的內(nèi)圈伸出外圈，當(dāng)兩軸承的外圈壓緊到一起時(shí)，外圈的原始間隙消除，可以增加軸承的預(yù)加載荷；串聯(lián)排列（兩軸承的寬端面在一個(gè)方向）安裝時(shí)，軸承的接觸角線同向且平行，可使兩軸承分擔(dān)同一方向的工作載荷。但使用這種安裝形式時(shí)，為了保證安裝的軸向穩(wěn)定性，兩對(duì)串聯(lián)排列的軸承必須在軸的兩端對(duì)置安裝。角接觸球軸承選用的常見問題有哪些？昆明234918BM1雙向推力角接觸球軸承</p><p
