在新国标中,配合是由孔公差带和轴公差带组合而成的,而公差带又是由“公差带大小”和“公差带位置”两个要素构成的。新国标对公差带的两个基本要素分别标准化,“公差带大小”由标准公差确定;“公差带位置”由基本偏差确定,形成了标准公差和基本偏差两个系列。第一节标准公差标准公差的定义是:“本标准表列的,用以确定公差带大小的任一公差”。 In the new national standard, the fit is made of a combination of hole tolerance and shaft tolerance, which is composed of two elements, “tolerance zone size” and “tolerance zone position”. The new national standard of the two basic elements of the tolerance zone are standardized, “tolerance zone size” determined by the standard tolerances; “tolerance zone position” determined by the basic deviation, formed a standard deviation and the basic deviation of the two series. Section 1 Standard Tolerance Standard Tolerance is defined as: “This standard listed to determine the tolerance band size of any tolerance.”
