style="text-indent:25px">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(chǎng)合。719或70系列適用于徑向空間小或轉(zhuǎn)速非常高的場(chǎng)合，72系列適用于載荷較重和中速的場(chǎng)合。對(duì)剛性要求較高的場(chǎng)合則要選用719系列。因?yàn)?19系列的軸承鋼球數(shù)量較多，其軸承剛性較高。由于719系列的軸承截面較小主軸的直徑可以加大，主軸的剛性也隨之增加，71814CTA角接觸球軸承，71814CTA角接觸球軸承，從而有效提高了機(jī)床主軸的剛性。所以719系列的軸承在機(jī)床主軸中應(yīng)用比其它兩個(gè)系列普遍，71814CTA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。71814CTA角接觸球軸承</p><div

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。</p><p

Bearings）是軸承的一種，它可同時(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。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。角接觸球軸承是非分離型的設(shè)計(jì)，內(nèi)外圈的兩側(cè)的肩部高低不一。雙列角接觸球軸承安裝時(shí)應(yīng)注意，雖然軸承可承受雙向軸向載荷，但若一側(cè)有裝球缺口時(shí)，則應(yīng)注意不要讓主要軸向載荷通過(guò)有缺口的一側(cè)溝邊。配對(duì)軸承應(yīng)用在：當(dāng)單個(gè)軸承的負(fù)荷承載能力不足（使用竄聯(lián)配置方式）或當(dāng)要承受聯(lián)合負(fù)荷或作用在兩個(gè)方向上的軸向負(fù)荷（使用背對(duì)背或面對(duì)面配置方式）。角接觸球軸承在低速工作時(shí)，較大的內(nèi)溝曲率半徑系數(shù)有利于角接觸球軸承摩擦力矩的減低。武漢7044ACETA-2RZ角接觸球軸承</p><p

1、使用部位:軸承適用于承受以徑向載荷為主的徑向與軸向的聯(lián)合負(fù)荷，通常以兩套軸承配對(duì)使用，主要應(yīng)于汽車的前后輪轂、主動(dòng)圓錐齒輪、差速器、減速器等傳動(dòng)部位。 2、允許轉(zhuǎn)速: 在安裝正確、潤(rùn)滑良好的環(huán)境下，允許為軸承極限轉(zhuǎn)速的0.3-0.5倍。一般正常情況下，以0.2倍的極限轉(zhuǎn)速為宜。 3、允許傾斜角:軸承一般不允許軸相對(duì)外殼孔有傾斜，如有傾斜，至大不超過(guò)2′。 4、允許溫度: 在承受正常的載荷，且潤(rùn)滑劑具有耐高溫性能，且潤(rùn)滑充分的條件下，一般角接觸球軸承允許在-30℃-150℃的環(huán)境溫度下工作。71814CTA角接觸球軸承</p><p
