軸承游隙選擇說明及游隙對(duì)照表

1、軸承游隙選擇說明及游隙對(duì)照表滾動(dòng)軸承的游隙分為徑向游隙ur和軸向游隙口且。它們分別表示一個(gè)套圈固定時(shí)，另一套圈沿徑向和軸向由一個(gè)極限位置到另一個(gè)極限位置的移動(dòng)量。各類軸承的徑向游隙ur和軸向游隙ua之間有一定的對(duì)應(yīng)關(guān)系，如圖1所示。徑向游隙又分為原始游隙、安裝游隙和工作游隙。原始游隙指未安裝前的游隙。各種軸承的原始游隙分組數(shù)值見表1表7.合理的軸承游隙的選擇，應(yīng)在原始游隙的基礎(chǔ)上，考慮因配合、內(nèi)外圈溫度差以及載荷等因素所引起的游戲變化，以使工作游隙接近于最佳狀態(tài)。由于過盈配合和溫度的影響，軸承的工作游隙小于原始游隙。0組徑向游隙值適用于一般的運(yùn)轉(zhuǎn)條件、常規(guī)溫度及常用的過盈配合，即對(duì)球軸承不得超

2、過j5、k5（軸）和J6（座孔）；對(duì)滾子軸承不得超過k5、m5（軸）和K6（座孔）。當(dāng)采用軸較緊配合、內(nèi)外圈溫差較大、需要降低摩擦力矩及深溝球軸承承受較大軸向載荷或需改善調(diào)心性能的場(chǎng)合，宜采用3、4、5組游隙值；當(dāng)旋轉(zhuǎn)精度要求較高或需嚴(yán)格限制軸向位移時(shí)，宜采用2組游隙值。對(duì)于球軸承，最適宜的工作游隙是趨于0。對(duì)于滾子軸承，可保持少量的工作游隙。在要求支撐剛性良好的部件中（例如機(jī)床主軸），軸承應(yīng)有一定的預(yù)緊。角接觸球軸承、圓錐滾子軸承以及內(nèi)圈帶錐孔的軸承等，由于結(jié)構(gòu)特點(diǎn)可以在安裝或使用過程中調(diào)整游隙。表1深溝球軸承的徑向游隙（GB/T4604-1993）（口m）公稱內(nèi)徑d/mm2組0組3組4組5
