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(dāng)軸承轉(zhuǎn)速達(dá)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(dāng)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?。划?dāng)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。7038ACETA-2RZ/HQ1角接觸球軸承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">單列角接觸球軸承與其他軸承不同之處，在于其只能承受一個方向的軸向載荷。所以決定了其在承受純徑向載荷時，由于滾動體載荷作用線與徑向載荷作用線不在同一徑向平面內(nèi)，產(chǎn)生內(nèi)部軸向分力，所以必須成對安裝使用。便拆卸耐磨型單列角接觸球軸承依靠改進(jìn)單列角接觸球軸承的結(jié)構(gòu)類型，從多方面提升了其性能，更與普通單列角接觸球軸承設(shè)計有所不同。當(dāng)前我國軸承的設(shè)計和制造技術(shù)基本上是依靠模仿，產(chǎn)品開發(fā)能力較低，而便拆卸耐磨型單列角接觸球軸承作為對單列角接觸球軸承的創(chuàng)新改進(jìn)，其意義是巨大的，一是體現(xiàn)我國行業(yè)者創(chuàng)新意識的覺醒，對產(chǎn)品的深入研究與思考，二是為之后的研究者繼續(xù)改進(jìn)軸承的性能提供新的思路和啟發(fā)。角接觸球軸承在軸向力作用下，接觸角會增大。7038ACETA-2RZ/HQ1角接觸球軸承</p><p style="text-indent:25px">角接觸球軸承具有高速性能好，剛度高，摩擦發(fā)熱低，壽命長等優(yōu)點。7038ACETA-2RZ/HQ1角接觸球軸承</p><p style="text-indent:25px">背對背（兩軸承的寬端面相對）安裝時，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；面對面（兩軸承的窄端面相對）安裝時，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，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方向）安裝時，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，為了保證安裝的軸向穩(wěn)定性，兩對串聯(lián)排列的軸承必須在軸的兩端對置安裝。7038ACETA-2RZ/HQ1角接觸球軸承</p></p><br
