style="text-indent:25px">圓錐滾子軸承屬于分離型軸承，軸承的內(nèi)、外圈均具有錐形滾道。該類軸承按所裝滾子的列數(shù)分為單列、雙列和四列圓錐滾子軸承等不同的結(jié)構(gòu)型式。單列圓錐滾子軸承可以承受徑向負(fù)荷和單一方向軸向負(fù)荷。當(dāng)軸承承受徑向負(fù)荷時(shí)，將會(huì)產(chǎn)生一個(gè)軸向分力，所以當(dāng)需要另一個(gè)可承受反方向軸向力的軸承來(lái)加以平衡。圓錐滾子軸承是指滾動(dòng)體為圓錐滾子的徑向推力式滾動(dòng)軸承。有小錐角和大錐角兩種。小錐角主要承受以徑向載荷為主的徑向和軸向聯(lián)合載荷，常成雙使用，反向安裝，內(nèi)外座圈可分別安裝，在安裝使用中可調(diào)整徑向和軸向游隙；大錐角主要承受以軸向載荷為主的軸向和徑向聯(lián)合載荷，一般不單獨(dú)用來(lái)承受純軸向載荷，當(dāng)成對(duì)配置(同名端相對(duì)安裝)時(shí)可用以承受純徑向載荷。滾動(dòng)軸承按滾動(dòng)力體分為球軸承和滾子軸承。滾子軸承是依靠主要零件之間的滾動(dòng)接觸來(lái)支撐轉(zhuǎn)動(dòng)零件的。不同的滾子軸承可以承受不同的徑向力和軸向力。通常滾針的硬度比互相配合的軸外圓和齒輪內(nèi)孔硬度略高。</p><div

style="text-indent:25px">深溝球軸承工作原理：深溝球軸承主要承受徑向載荷，也可同時(shí)承受徑向載荷和軸向載荷。當(dāng)其*承受徑向載荷時(shí)，接觸角為零。當(dāng)深溝球軸承具有較大的徑向游隙時(shí)，具有角接觸軸承的性能，可承受較大的軸向載荷，深溝球軸承的摩擦系數(shù)很小，極限轉(zhuǎn)速也很高。軸承特性：深溝球軸承是較常用的滾動(dòng)軸承。它的結(jié)構(gòu)簡(jiǎn)單，使用方便。主要用來(lái)承受徑向載荷，但當(dāng)增大軸承徑向游隙時(shí)，具有一定的角接觸球軸承的性能，可以承受徑、軸向聯(lián)合載荷。在轉(zhuǎn)速較高又不宜采用推力球軸承時(shí)，也可用來(lái)承受純軸向載荷。與深溝球軸承規(guī)格尺寸相同的其它類型軸承比較，此類軸承摩擦系數(shù)小，極限轉(zhuǎn)速高。但不耐沖擊，不適宜承受重載荷。深溝球軸承裝在軸上后，在軸承的軸向游隙范圍內(nèi)，可限制軸或外殼兩個(gè)方向的軸向位移，因此可在雙向作軸向定位。此外，該類軸承還具有一定的調(diào)心能力，當(dāng)相對(duì)于外殼孔傾斜2′～10′時(shí)，仍能正常工作，但對(duì)軸承壽命有一定影響。軸承的密封可分為自帶密封和外加密封兩類。遼寧不銹鋼軸承品牌</p><p
