本文分析了具有过盈的外配合对其内配合的影响;研究了外配合为过盈配合和过渡配合的两种情况;给出了受装配变形影响后,孔的收缩变形、内配合的配合间隙与过盈、均方差以及概率分布等的计算方法与公式.另外,针对钻模等典型情况,分别按国际标准ISO4247-1977和国家标准GB159-174-59所规定的配合进行了分析和计算,并据此对两种配合制作出了比较与评价.
In this paper, we analyze the influence of the interference with the external coordination on the internal coordination; the two cases that the external coordination is the interference fit and the transition coordination are given; the shrinkage and deformation of the hole, Gap and interference, mean square deviation and probability distribution etc. In addition, according to the typical situations such as drilling, the international standard ISO4247-1977 and the national standard GB159-174-59 are respectively analyzed and calculated , And accordingly made a comparison and evaluation of the two kinds of cooperation.
