过盈量是指基本尺寸相同的相互结合的孔和轴公差带之间的关系。决定结合的松紧程度。孔的尺寸减去相配合轴的尺寸所得的代数差为正时称间隙，为负时称过盈，有时也以过盈为负间隙。

The research curve indicated that, static strength reliability is decreasing with the magnitude of interference value increasing, while anti-slide reliability is increasing with the magnitude of interference value increasing.
研究表明,静强度可靠度随着过盈量的增加而减小,而不滑移可靠度随着过盈量的增加而增大,也就是说,轮盘上的应力和过盈装配产生的摩擦扭矩随着弹性模量的增加而增大。
