style="text-indent:25px">圓錐孔雙列圓柱滾子軸承屬于線性接觸軸承,其承載能力和剛度高于點(diǎn)接觸的角接觸軸承，常用于載荷較大、要求剛度較高，而轉(zhuǎn)速相對(duì)來(lái)說(shuō)不很高的中、大、重型機(jī)床主軸系統(tǒng)中。雙列圓柱滾子軸承直徑與寬度之比一般在4~7之間，由于雙列圓柱滾子軸承的徑寬比較大，導(dǎo)致在主軸箱孔中和主軸上安裝時(shí)的導(dǎo)向性能較差。再者大型機(jī)床零件尺寸和質(zhì)量較大，給裝配工作帶來(lái)一定的難度，容易造成安裝軸承時(shí)的力量不均勻。以上的種種原因，導(dǎo)致主軸軸承的內(nèi)外圈安裝位置偏移,軸承滾動(dòng)體與軸承的內(nèi)外圈接觸不良，致使主軸剛度和回轉(zhuǎn)精度降低。檢驗(yàn)主軸軸承的內(nèi)外圈安裝端正的方法如下:在預(yù)緊軸承內(nèi)圈的過程中，不斷的轉(zhuǎn)動(dòng)主軸，同時(shí)觀察軸承滾動(dòng)體的轉(zhuǎn)動(dòng)情況。</p><p

調(diào)心性能：軸中心線相對(duì)軸承座孔中心線傾斜時(shí)，軸承仍能正常工作。雙列向心球面球軸承和雙列向心球面滾子軸承具有良好的調(diào)心性能。滾軸承工作轉(zhuǎn)速應(yīng)低于極限轉(zhuǎn)速。選用高精度軸承、改善保持架結(jié)構(gòu)和材料、采用油霧潤(rùn)滑、改善冷卻條件等，都可以提高極限轉(zhuǎn)速。 2. 潤(rùn)滑性能：軸承的潤(rùn)滑目有減少軸承內(nèi)部摩擦及磨損，防止燒粘；延長(zhǎng)其使用壽命；排出摩擦熱、冷卻，防止軸承過熱，防止?jié)櫥妥陨砝匣?；也有防止異物侵入軸承內(nèi)部，或防止生銹、腐蝕之效果。雙列圓柱滾子軸承潤(rùn)滑的目的是什么？</p><div style="width:100%;text-align: center;"><img

style="text-indent:25px">內(nèi)圈或外圈無(wú)擋邊的圓柱滾子軸承，其內(nèi)圈和外圈可以向軸向作相對(duì)移動(dòng)，所以可以作為自由端軸承使用。在內(nèi)圈和外圈的某一側(cè)有雙擋邊，另一側(cè)的套圈有單個(gè)擋邊的圓柱滾子軸承，可以承受一定程度的一個(gè)方向軸向負(fù)荷。一般使用鋼板沖壓保持架，或銅合金車制實(shí)體保持架。但也有一部分使用聚酰胺成形保持架。圓柱滾子軸承特點(diǎn)： 1. 滾子與滾道為線接觸或修下線接觸，徑向承載能力大，適用于承受重負(fù)荷與沖擊負(fù)荷。 2. 摩擦系數(shù)小，適合高速，極限轉(zhuǎn)速接近深溝球軸承。 3. N型及NU型可軸向移動(dòng)，能適應(yīng)因熱膨脹或安裝誤差引起的軸與外殼相對(duì)位置的變化，可作自由端支承使用。 4. 對(duì)軸或座孔的加工要求較高，軸承安裝后外圈軸線相對(duì)偏斜要嚴(yán)加控制，以免造成接觸應(yīng)力集中。 5.
