style="text-indent:25px">雙列角接觸球軸承的特點(diǎn)是可以同時(shí)承受徑向和軸向載荷的聯(lián)合載荷，限制軸的兩方面的軸向位移。雙列角接觸球軸承與雙向推力球軸承相比，這種軸承極限轉(zhuǎn)速較高，接觸角為32度，剛性好，可承受傾覆力矩大，普遍用于小汽車的前輪輪轂中（有的車型也用同尺寸的雙列圓錐滾子軸承）。雙列角接觸球軸承的結(jié)構(gòu)變形有：A型：外徑小于或等于90mm軸承的標(biāo)準(zhǔn)設(shè)計(jì)。無(wú)裝球缺口，因此能承受相等的雙向軸向載荷。采用輕型玻璃纖維增強(qiáng)尼龍66保持架，軸承溫升很小。A型：外徑大于90mm軸承的標(biāo)準(zhǔn)設(shè)計(jì)。一側(cè)有裝球缺口，配備z鋼板沖壓保持架或黃銅實(shí)體保持架。E型：屬加強(qiáng)型結(jié)構(gòu)，一側(cè)帶裝球缺口，可以裝更多的鋼球，因此承載能力較高。烏魯木齊B7003CTA-2RZ角接觸球軸承定位預(yù)緊：沿著施力方向加上預(yù)緊力，讓間隙為0。</p><div

style="text-indent:25px">角接觸球軸承的周全與軸的配合一般為過渡配合，座圈與軸承座孔的配合一般為間隙配合，所以這種軸承較易安裝，雙向推力軸承的中軸應(yīng)在軸上固定，以防止相對(duì)于軸轉(zhuǎn)動(dòng)。軸承的安裝方法，一般情況下是軸旋轉(zhuǎn)的情況居多，因此內(nèi)圈與軸的配合為過贏配合，軸承外圈與軸承室的配合為間隙配合。軸承內(nèi)圈與軸使緊配合，外圈與軸承座孔是較松配合時(shí)，可用壓力機(jī)將軸承先壓裝在軸上，然后將軸連同軸承一起裝入軸承座孔內(nèi)，壓裝時(shí)在軸承內(nèi)圈端面上，墊一軟金屬材料做的裝配套管(銅或軟鋼)，裝配套管的內(nèi)徑應(yīng)比軸頸直徑略大，外徑直徑應(yīng)比軸承內(nèi)圈擋邊略小，以免壓在保持架上。</p><p style="text-indent:25px">角接觸球軸承安裝時(shí)，要在套圈端面的圓周上施加均等的壓力，將套圈壓入，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。在過盈量較小的情況下，可在常溫下用套筒壓住角接觸球軸承套圈端面，用鎯頭敲打套筒，通過套筒將套圈均衡地壓入。如果大批量安裝時(shí)，可采用液壓機(jī)。壓入時(shí)，應(yīng)保證外圈端面與外殼臺(tái)肩端面，內(nèi)圈端面與軸臺(tái)肩端面壓緊，不允許有間隙。當(dāng)過盈量較大時(shí)，可采用油浴加熱或感應(yīng)器加熱軸承方法來(lái)安裝，加熱溫度范圍為80℃-100℃，至高不能超過120℃。同時(shí)，應(yīng)用螺母或其它適當(dāng)?shù)姆椒ňo固軸承，以防止軸承冷卻后寬度方向收縮而使套圈與軸肩之間產(chǎn)生間隙。角接觸球軸承接觸角越大，軸向承載能力越高。</p><div
