摘要
要正确地进行尺寸链的分析计算,先要查明尺寸链的封闭环。查尺寸链的组成环时,可利用尺寸链的封闭性规律。方法:从封闭环两端相连的任一组成环开始,依次查找相互联系而又影响封闭环大小的尺寸,直至封闭环的另一端为止,这些相互连接成封闭形式的尺寸,便是该尺寸链的全部组成环。
To correctly to the analysis of the dimension chain calculating,to find out the first dimension chain closed ring.Check the composition of the dimension chain rings,available dimensional chain blocking rule.Method is that based on the closed ring connected to both ends of any one of the composition ring began,in order to find mutual connections and influence the size of the closed ring size,Until the other end of the closing link so far,these mutual connection into the closed form of size,it is the size chain of all component ring.
