摘要
本文论述了延伸公差带的应用,主要用于螺纹件及压配合零件的连接,控制位置度和对称度的公差,以保证零件的功能要求和顺利装配。讨论了连接件与被连接件的厚度之间的变化对延伸公差带效果的影响。探讨了应用延伸公差带时采用最大实体原则时的最大补偿问题。
This paper describes the application of projected tolerance zone, mainly in threaded parts and parts with interference fit to control the tole ranee in position or symmetry so that the function and assembling of these parts be ensured.The effect of the variation of thickness between the mating parts on the projected tolerance zone is discussed, as also the maximum compens ation when applying the projected tolerance zone under maximum material principle.
