GB/T1800的本部分规定了孔和轴常用公差带的极限偏差数值,其数值是按GB/T1800.1中的标准公差和基本偏差数值表计算得到的。它包括孔的上极限偏差ES和轴的上极限偏差es、孔的下极限偏差EI和轴的下极限偏差ei的数值(见图1)。 本部分适用于圆柱和非圆柱形光滑工件的尺寸要素。
This part of GB/T 1800 gives values of the limit deviations for commonly used tolerance classes (zones) for holes and shafts calculated from the tables of standard tolerances and fundamental deviations given in GB/T 1800.1. This part of GB/T 1800 covers values for the upper limit deviations ES (for holes) and es (for shafts), and the lower limit deviations EI (for holes) and ei (for shafts) (see figure 1).
This part of GB/T 1800 is applicable to the dimensional elements for cylindrical and non-cylindrical plain workpieces.
