style="text-indent:25px">軸承檢查與判斷：為了判斷拆下的軸承能否重新使用，要著重檢查其尺寸精度、旋轉(zhuǎn)精度、內(nèi)部游隙以及配合面、滾道面，云南單向軸承、保持架和密封圈等。大型軸承因不能用手旋轉(zhuǎn)，云南單向軸承，注意檢查滾動(dòng)體、滾道面、保持架、擋邊面等外觀，軸承的重要性愈高愈須慎重檢查。滾動(dòng)軸承發(fā)熱的原因及其排除方法。軸承精度低：選用規(guī)定精度等級(jí)的軸承。主軸彎曲或箱體孔不同心：修復(fù)主軸或箱體。潤(rùn)滑不良：選用規(guī)定牌號(hào)的潤(rùn)滑材料并適當(dāng)清潔。裝配質(zhì)量低：提高裝配質(zhì)量。軸承內(nèi)外殼跑圈：更換軸承及相關(guān)磨損部件，云南單向軸承。軸向力太大：清洗、調(diào)正密封口環(huán)間隙要求0.2～0.3mm之間，更正葉輪平衡孔直徑及校驗(yàn)靜平衡值。軸承損壞：更換軸承。在安裝任何滾針軸承之前，必須確保所有部件清潔且工作正常。云南單向軸承</p><div

style="text-indent:25px">滾針軸承的徑向垂直載荷主要來源于齒輪的徑向力，徑向力越大，作用在接觸部位的壓力越大(小于4000MPa)，越容易加劇相對(duì)運(yùn)動(dòng)時(shí)的磨損。齒輪的徑向力的大小是由所傳遞的扭矩決定的，通常不能改動(dòng)，而接觸部位的壓力可以通過滾針軸承的優(yōu)化來降低。可選擇的優(yōu)化方案為:通過增加滾針長(zhǎng)度、滾針個(gè)數(shù)、滾針直徑等方法，降低局部壓力，提升耐磨性，預(yù)防微動(dòng)磨損。往復(fù)運(yùn)動(dòng)的位移是由滾針軸承的軸向間隙(0.15～0.45mm)和徑向間隙(0.015～0.058mm)引起的。間隙越大，往復(fù)運(yùn)動(dòng)的位移越大，速度越快，摩擦功越高，越容易引起局部的磨損?？蛇x擇的優(yōu)化方案有兩個(gè):一個(gè)是通過提高齒輪和軸的軸向定位精度來降低軸向間隙(0.1～0.35mm);另一個(gè)是通過減小軸和孔的直徑公差或把軸和孔的直徑公差分組匹配來降低徑向間隙(0.009～.048mm)。通過間隙的優(yōu)化，可明顯降低往復(fù)運(yùn)動(dòng)的位移，降低摩擦功，起到預(yù)防微動(dòng)磨損的作用。</p><p
