二、尺寸链的基本解法——极限法极限法或称“最大最小法”。前面已提到,用极限法解尺寸链,是基于下述假设:尺寸链组成环中所有增环同时达到最大极限尺寸,而所有减环又同时达到最小极限尺寸的条件下,使封闭环达到其最大极限尺寸;反之亦然。总之是从估计可能发生的最极端情况为出发点来解尺寸链的,下面介绍这种计算方法的基本关系式及其应用。1.用极限法解尺寸链的基本关系式
Second, the basic solution of the size chain - limit method limit method or “maximum and minimum method.” As mentioned earlier, using the limit method to solve the dimensioning chain is based on the assumption that the size of the chain is such that all the rings in the ring reach the maximum limit at the same time, and all the reduction rings reach the minimum limit at the same time, Its maximum limit size; and vice versa. In short, it is to solve the dimensioning chain from the most extreme situation that may occur. The following describes the basic relationship and its application of this calculation method. 1. Using limit method to solve the basic relationship between the size chain
