GB/T1800的本部分規(guī)定了孔和軸常用公差帶的極限偏差數(shù)值,其數(shù)值是按GB/T1800.1中的標(biāo)準(zhǔn)公差和基本偏差數(shù)值表計算得到的。它包括孔的上極限偏差ES和軸的上極限偏差es、孔的下極限偏差EI和軸的下極限偏差ei的數(shù)值(見圖1)。 本部分適用于圓柱和非圓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.
