style="text-indent:25px">角接觸球軸承具有較高的極限轉(zhuǎn)速，也可以同時承受徑向和軸向載荷。角接觸球軸承按結(jié)構(gòu)分為：單列角接觸球軸承；雙列角接觸球軸承：雙列角接觸球軸承是雙排球的角接觸球軸承，但占用更小的軸向空間（厚度比兩個單列角接觸球軸承稍窄），可以限制軸或外殼雙向軸向位移，接觸角為30°。可提供剛性較高的軸承配置，并能承受傾覆力矩。普遍應用于小汽車的前輪輪轂中。四點角接觸球軸承：分離型軸承，可承受徑向載荷及雙向軸向載荷，同尺寸軸承厚度小于雙列角接觸球軸承。多用于軋機軋輥定位。常見有雙半外圈（QJF型）和雙半內(nèi)圈（QJ型）兩種。推力角接觸球軸承：雙向推力角接觸球軸承與雙列圓柱滾子軸承配套使用可以承受雙向軸向載荷。分為2344和2347兩個系列，2344系列用于與雙列圓柱滾子軸承錐孔小端配合，而2347與大端配合。</p><p style="text-indent:25px">高速精密角接觸球軸承，主要用于載荷較輕的高速旋轉(zhuǎn)場合，要求軸承高精度、高轉(zhuǎn)速、低溫升低振動和一定的使用壽命。常作高速電主軸的支承件成對安裝使用，是內(nèi)表面磨床高速電主軸的關(guān)鍵配套件。高速精密角接觸球軸承使用壽命與安裝有很大關(guān)系，應注意以下事項：1.軸承安裝應在無塵，潔凈的房間內(nèi)進行，軸承要經(jīng)過精心選配，軸承用隔圈要經(jīng)過研磨，在保持內(nèi)外圈隔圈等高的前提下，隔圈平行度應控制在1um以下;2.軸承安裝前應清洗干凈，清洗時內(nèi)圈斜坡朝上，手感應靈活，無停滯感，晾干后，放入規(guī)定量油脂，如屬油霧潤滑應放入少量的油霧油;3.軸承安裝應采用專門工具，受力均勻，嚴禁敲打;4.軸承存放應清潔通風，無腐蝕氣體，相對濕度不超過65%，長期保管應定期防銹。定壓預緊：借助彈簧始終給軸承施加一個恒定的預緊力。</p><div

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，軸承摩擦力矩隨著軸承的轉(zhuǎn)速增大而增大，這是因為此時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)；當軸承轉(zhuǎn)速達到一定值時，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。剛開始運轉(zhuǎn)時，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小；當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。接觸球軸承軸向載荷能力由接觸角決定，并隨接觸角的增大而增大。B7001ACTA-2RZ/HQ1角接觸球軸承</p><p

style="text-indent:25px">鋼球引導陶瓷纖維保持架：保持架使用陶瓷纖維作為標準配置，一般也可使用GRPA66-25，PEEK，PL以及酚醛夾布膠木管等,但相比較而言陶瓷纖維材質(zhì)的更適合與陶瓷球組合使用，因為陶瓷纖維保持架具有韌性好、強度高，質(zhì)量輕、可塑性好，自潤滑性好、抗疲勞能力強、耐高溫、噪音小、溫升低和轉(zhuǎn)速高。所謂韌性好是指此種材料不宜斷裂，在一般條件下不會輕易被損壞;陶瓷纖維比其他材質(zhì)所承受的載荷更大;由于陶瓷纖維的密度小，質(zhì)量輕，所以在軸承旋轉(zhuǎn)時，所產(chǎn)生的離心力也小;由于陶瓷纖維本身的特性，自潤滑性比其他材料要好得多并且抗疲勞能力強;陶瓷纖維和陶瓷球組合使用可以在高達600C的條件下正常工作;隨著社會的發(fā)展，人們對于噪音的聲音越來越敏感，所以噪音小是陶瓷纖維的突出特點;在運轉(zhuǎn)時不會產(chǎn)生過高的溫升，而導致軸承壽命降低;陶瓷纖維保持架和陶瓷球組合軸承的轉(zhuǎn)速較普通軸承的轉(zhuǎn)速高。鎮(zhèn)江7204ACTN/HQ1角接觸球軸承</p><p
