公差原则与配合件的可装配性分析

Analysis of the assembling of tolerance principles and cooperating parts

三种公差原则在一定条件下都可以满足配合件的可装配性.从制造成本、检验效率、假废品三个方面分析了三种公差原则在满足配合件的可装配性上的差异.当配合件仅要求可装配且无其他功能要求时,若进行尺寸设计,最适宜采用的公差原则是最大实体原则.

This paper demonstrates three tolerance principles that enable cooperating parts to be assembled in certain conditions.It also analyses the discrepancies of the three tolerance principles from aspects of manufacturing costs,examining efficiency and waste products.
