配合可由孔、轴公差带结合而成,从理论上讲,任意一个轴的公差带可和任意一个孔的公差带组成配合。因此,配合能反映相配零件间的不同关系。新国标把“基本尺寸相同的、相互结合的孔和轴公差带之间的关系”定义为配合,既说明了配合的条件,也反映了配合的性质。为了减少定值量、刃具的规格,新国标与旧国标一样,也对配合规定了两种基准制度,一为基孔制,一为基轴制。基孔制的孔叫基准孔,它的基本偏差
With the combination of holes and shaft tolerance band, in theory, the tolerance band of any one shaft can be matched with the tolerance band of any one hole. Therefore, with the ability to reflect the matching between the different parts of the relationship. The new national standard to “the same basic dimensions, the mutual relationship between the hole and the shaft tolerance band” is defined as cooperation, both to illustrate the conditions with the match, but also reflects the nature of the match. In order to reduce the amount of fixed value, the specifications of the cutting tool, the new national standard and the old national standard, but also with the provisions of the two benchmark system, a base hole system, a base axis system. Base hole hole called the reference hole, its basic deviation
