style="text-indent:25px">軸承轉(zhuǎn)速對(duì)軸承摩擦力矩的影響：角接觸球軸承低速旋轉(zhuǎn)時(shí)，軸承摩擦力矩隨著軸承的轉(zhuǎn)速增大而增大，這是因?yàn)榇藭r(shí)鋼球與滾道之間彈流潤(rùn)滑膜還沒(méi)有建立，軸承基本處于干涸潤(rùn)滑狀態(tài)；當(dāng)軸承轉(zhuǎn)速達(dá)到一定值時(shí)，即鋼球與滾道之間潤(rùn)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(rùn)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(duì)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(duì)摩擦力矩的影響。剛開(kāi)始運(yùn)轉(zhuǎn)時(shí)，隨著軸承工作溫度的升高，潤(rùn)滑油粘度下降，從而造成軸承摩擦力矩逐漸減小；當(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。</p><p style="text-indent:25px">單列角接觸球軸承只支持一個(gè)方向的軸向載荷，而雙列角接觸球軸承支持兩個(gè)方向的軸向載荷。角接觸軸承能夠做到與徑向類(lèi)軸承相同的精度公差，但設(shè)計(jì)的接觸角為15度，30度和40度，以適應(yīng)更大的推力載荷。角接觸球軸承通過(guò)非對(duì)稱座圈支撐徑向和軸向載荷，不對(duì)稱座圈在一定角度內(nèi)容納軸承的球形滾動(dòng)元件，也稱為軸承滾珠。軸承與其軸線之間的角度越深，軸承承受的軸向載荷就越大。因?yàn)檩S向載荷與徑向載荷成反比，所以軸向載荷越大意味著徑向載荷越小。角接觸球軸承采用單列和雙列配置，具體取決于其承載的負(fù)載方向。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。</p><div

style="text-indent:25px">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。在軸承使用時(shí)應(yīng)注意使不帶裝球缺口的一側(cè)滾道承受主要載荷。雙列角接觸球軸承能承受較大的徑向負(fù)荷為主的徑向和軸向聯(lián)合負(fù)荷和力矩負(fù)荷，限制軸的兩方面的軸向位移。主要用于限制軸和外殼雙向軸向位移的部件中。雙列角接觸球軸承內(nèi)、外圈之間的可傾斜性有限，允許傾斜角取決于軸承的內(nèi)部間隙、軸承尺寸、內(nèi)部設(shè)計(jì)及作用于軸承上的力和力矩，而較大允許傾斜角應(yīng)保證軸承內(nèi)不會(huì)產(chǎn)生過(guò)高的附加應(yīng)力。若軸承內(nèi)、外圈之間存在傾斜角，將影響軸承的壽命，同時(shí)造成軸承運(yùn)轉(zhuǎn)精度下降，運(yùn)轉(zhuǎn)噪聲增大。雙列角接觸球軸承一般采用尼龍保持架或黃銅實(shí)體保持架。金華709CTA角接觸球軸承</p><p
