轴承游隙标准.docx

1、轴承游隙标准轴承游隙所谓轴承游隙，即指轴承在未安装于轴或轴承箱时，将其内圈或外圈的一方固定，然后便未被固定的一方做径向或轴向移动时的移动量。根据移动方向，可分为径向游隙和轴向游隙。运转时的游隙（称做工作游隙）的大小对轴承的滚动疲劳寿命、温升、噪声、振动等性能有影响。测量轴承的游隙时，为得到稳定的测量值，一般对轴承施加规定的测量负荷。因此，所得到的测量值比真正的游隙（称做理论游隙）大，即增加了测量负荷产生的弹性变形量。但对于滚子轴承来说，由于该弹性变形量较小，可以忽略不计。安装前轴承的内部游隙一般用理论游隙表示。游隙的选择 从理论游隙减去轴承安装在轴上或外壳内时因过盈配合产生的套圈的膨胀量或收缩

2、后的游隙称做“安装游 隙”。在安装游隙上加减因轴承内部温差产生的尺寸变动量后的游隙称做“有效游隙”。轴承安装有机械上承受一定的负荷放置时的游隙，即有效游隙加上轴承负荷产生的弹性变形量后的以便称做“工作游隙”。如图所示，当工作游隙为微负值时，轴承的疲劳寿命最长但随着负游隙的增大疲劳寿命同显著下降。因此，选择轴承的游隙时，一般使工作游隙为零或略为正为宜。图工作游隙与疲劳寿命的关系另外，需提高轴承的刚性或需降低噪声时，工作游隙要进一步取负值，而在轴承温升剧烈时，工作游隙则要进一步取正值等等，还必须根据使用条件做具体分析。color=#000000表深沟球轴承（圆柱孔）的径向游隙 单位um轴承公称内径
