滾動軸承工作時，由于滾動體與套圈滾道之間接觸面積很小，軸承在承受載荷時，尤其是在承受較大載荷的情況下，接觸表面的接觸壓力很大。為了防止在高接觸應(yīng)力下發(fā)生過大的塑性變形，使軸承精度喪失或發(fā)生表面裂紋，因此，要求軸承鋼應(yīng)具有高的彈性極限。 </p> <p> <br /> </p> <p> 適宜的硬度 </p> <p> 硬度是滾動軸承的重要指標(biāo)之一。它與材料接觸疲勞強(qiáng)度、耐磨性、彈性極限有著密切的關(guān)系，直接影響著滾動軸承的壽命，軸承的硬度通常要根據(jù)軸承承受載荷的方式和大小、軸承尺寸和壁厚的總體情況來決定。滾動軸承用鋼的硬度要適宜，過大或過小都將影響軸承使用壽命。眾所周知，滾動軸承的主要失效形式是接觸疲勞破壞，以及由于耐磨性差或尺寸不穩(wěn)定而使軸承精度喪失；軸承零件如果缺乏一定的韌性，在承受較大沖擊載荷時又會由于發(fā)生脆斷而導(dǎo)致軸承的破壞。所以，一定要根據(jù)軸承的具體情況和破壞的方式來確定軸承的硬度。對于由于疲勞剝落或耐磨性差使軸承精度喪失的情況，軸承零件應(yīng)選用較高的硬度；對于承受較大沖擊載荷的軸承(例如軋機(jī)：軸承、鐵路軸承和一些汽車軸承等)，應(yīng)適當(dāng)降低硬度以提高軸承的韌性是十分必要的。

推力球軸承是一種結(jié)合型軸承，軸圈、座圈能夠和維持架、鋼球的組件結(jié)合。軸圈是與軸相合作的套圈，座圈是與軸承座孔相合作的套圈，和軸之間有間隙。依據(jù)其構(gòu)造方式分成單向推力球和雙向推力球軸承。 </p> <p> 1、德國FAG、INA軸承產(chǎn)品推力球軸承可接受一個位置的軸向負(fù)荷，雙向推力球軸承可接受兩個位置的軸向負(fù)荷。它們均使不得接受徑向負(fù)荷。單向推力球軸承由一個軸圈、一個軸承座圈、以及一個球與維持架推力組件所組成。 </p> <p> FAG主軸高精密軸承（B70系列、B719系列、B718系列、HS70系列、HSS系列、HCS系列） </p> <p> FAG軸承全系列的FAG軸承產(chǎn)品（包括FAG深溝球軸承、FAG圓柱滾子軸承、FAG球面滾子軸承等）。 </p><p> <br /> </p> <p> <br /> </p> <p> 軸承的調(diào)心性能 </p> <p> <br /> </p> <p> 當(dāng)軸的中心線與軸承座中心線不重合而有角度誤差時，或因軸受力而彎曲或傾斜時，會造成軸承的內(nèi)、外圈軸線發(fā)生傾斜。這時，應(yīng)采用有一定調(diào)心性能的調(diào)心球軸承或調(diào)心滾子軸承。這類軸承在內(nèi)外圈軸線有不大的相對偏斜時仍能正常工作。 </p> <p> 圓柱滾子軸承和滾針軸承對軸承的偏斜只為敏感，這類軸承在偏斜狀態(tài)下的承載能力可能低于球軸承。因此在軸的剛度和軸承座孔的支承剛度較低時，應(yīng)盡量避免使用這類軸承。 </p> <p> <br /> </p> <p> 軸承的安裝和拆卸 </p> <p> <br /> </p> <p> 便于裝拆，也是選擇軸承類型時應(yīng)考慮的一個因素。在軸承座沒有剖分面而必須沿軸向安裝和拆卸軸承部件時，應(yīng)優(yōu)先選用內(nèi)外圈可分離的軸承（如N0000、NA0000、30000等）。當(dāng)軸承在長軸上安裝時，為了便于拆卸，可選用其內(nèi)圈孔為1：12的圓錐孔（用以安裝在緊定襯套上）的軸承。 </p> <p> <br /> 鍛件網(wǎng)狀碳化物、晶粒度、流線：影響軸承疲勞壽命。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="浙江進(jìn)口ABL,ABL"

必須認(rèn)識到游隙是INA軸承能否正常工作的一個重要因素。選擇適宜的軸承游隙對軸承益處多：可以使負(fù)荷在滾動體之間分布合理；能限制軸（或外殼）的軸向和徑向位移以保證軸的旋轉(zhuǎn)精度；使進(jìn)口軸承在要求的溫度下能正常工作；可減少軸承工作時的振動和噪聲等，由此可見，軸承游隙對軸承壽命、溫升、振動和噪聲有很大的影響。在選擇軸承游隙時，除應(yīng)考慮軸承的工作條件（如負(fù)荷、轉(zhuǎn)速、溫度等）和對軸承使用性能的要求（如磨擦力矩、振動和噪聲、旋轉(zhuǎn)精度等）之外，還應(yīng)考慮： </p> <p> 1．軸承與軸和外殼的過盈配合導(dǎo)致游隙減小； </p> <p> 2．軸承工作時，內(nèi)、外套圈的溫度差導(dǎo)致游隙減??； </p> <p> 3．軸和外殼的制造材料因膨脹系數(shù)不同導(dǎo)致游隙減小或增大。 </p> <p> 使用經(jīng)驗表明，對于球軸承只適宜的工作游隙近似為零；對于滾子軸承只適宜的工作狀況應(yīng)保持少量的工作游隙。在要求支承剛性良好的部件中（例如機(jī)床主軸），也可有一定數(shù)值的預(yù)緊。 ABL軸承，深溝球軸承是滾動軸承，基本型的深溝球軸承由一個外圈，一個內(nèi)圈、一組鋼球和一組保持架；浙江進(jìn)口ABL</p><p
