style="text-indent:25px">角接觸球軸承的設(shè)計(jì)用于高速，高精度行業(yè)，主要用于中高轉(zhuǎn)速的需要精密軸向定位和徑向定位，高精度旋轉(zhuǎn)等工況。例如：數(shù)控車(chē)床主軸，各類(lèi)磨床工件軸，磨床砂輪主軸，光伏切片機(jī)，真空泵，風(fēng)機(jī)，精密傳動(dòng)機(jī)械等。角接觸軸承是機(jī)床主軸等應(yīng)用的常見(jiàn)選擇，在更高的精度水平下，其中存在高精度和高推力載荷。它們通常成對(duì)安裝，在任何方向提供推力，并且在至關(guān)重要的應(yīng)用中具有良好的穩(wěn)定性。雙列角接觸軸承提供軸剛性，緊湊性，更高的徑向載荷以及兩個(gè)方向上的適度推力。</p><p style="text-indent:25px">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，可以增加其徑向和軸向的支承角度剛性，抗變形能力提高；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，其支承角度剛性較小。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。角接觸球軸承能在較高的轉(zhuǎn)速下工作。</p><div

style="text-indent:25px">精密角接觸球軸承有719、70和72系列三種直徑的系列，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，從而有效提高了機(jī)床主軸的剛性。因此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。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。南昌7009ACTA角接觸球軸承</p><p style="text-indent:25px">角接觸球軸承的周全與軸的配合一般為過(guò)渡配合。南昌7009ACTA角接觸球軸承</p><p style="text-indent:25px">角接觸球軸承的選型要考慮使用的工況及限定空間。工況主要是包括使用環(huán)境、精度、轉(zhuǎn)速、受力方向及大小等。高速、小載荷的一般采用非金屬保持架；低速、重載采用金屬保持架；高溫環(huán)境采用金屬保持架；中溫環(huán)境一般采用工程塑料保持架，一般尼龍保持架使用溫度不能超過(guò)120度；對(duì)于超高速、耐磨、低溫升、長(zhǎng)壽命及高可用環(huán)境下可以使用混合陶瓷球軸承，滾珠采用氮化硅陶瓷。若對(duì)軸的精度要求高，比如機(jī)床主軸一般選用P4或P2的軸承；中等精度的一般選擇P5或P4級(jí)別；一般精度可選擇更經(jīng)濟(jì)的P0或P6級(jí)別。若要求高轉(zhuǎn)速，首先要選擇接觸角為15°極限轉(zhuǎn)速比較高的輕系列軸承；若要求承受軸向大的載荷可選用接觸角為40°的2系列或3系列角接觸球軸承；若需要同時(shí)考慮轉(zhuǎn)速和軸向載荷可選擇接觸角為25°的角接觸球軸承。南昌7009ACTA角接觸球軸承</p></p><br
