轴承游隙选择说明及游隙对照表

1、轴承游隙选择说明及游隙对照表滚动轴承的游隙分为径向游隙ur和轴向游隙口且。它们分别表示一个套圈固定时，另一套圈沿径向和轴向由一个极限位置到另一个极限位置的移动量。各类轴承的径向游隙ur和轴向游隙ua之间有一定的对应关系，如图1所示。径向游隙又分为原始游隙、安装游隙和工作游隙。原始游隙指未安装前的游隙。各种轴承的原始游隙分组数值见表1表7.合理的轴承游隙的选择，应在原始游隙的基础上，考虑因配合、内外圈温度差以及载荷等因素所引起的游戏变化，以使工作游隙接近于最佳状态。由于过盈配合和温度的影响，轴承的工作游隙小于原始游隙。0组径向游隙值适用于一般的运转条件、常规温度及常用的过盈配合，即对球轴承不得超

2、过j5、k5（轴）和J6（座孔）；对滚子轴承不得超过k5、m5（轴）和K6（座孔）。当采用轴较紧配合、内外圈温差较大、需要降低摩擦力矩及深沟球轴承承受较大轴向载荷或需改善调心性能的场合，宜采用3、4、5组游隙值；当旋转精度要求较高或需严格限制轴向位移时，宜采用2组游隙值。对于球轴承，最适宜的工作游隙是趋于0。对于滚子轴承，可保持少量的工作游隙。在要求支撑刚性良好的部件中（例如机床主轴），轴承应有一定的预紧。角接触球轴承、圆锥滚子轴承以及内圈带锥孔的轴承等，由于结构特点可以在安装或使用过程中调整游隙。表1深沟球轴承的径向游隙（GB/T4604-1993）（口m）公称内径d/mm2组0组3组4组5
