起重机联轴器的疲劳、强度计算已在很多文献中有所介绍。其中关于某些主要受强度控制的联轴器强度计算公式更是形式不一。这样,我们就很容易提出一系列的问题:究竟应用哪一个公式进行计算呢?公式本身有没有欠缺之处?它们的计算原理是否相同?我认为要回答这些问题必须要有正确的载荷计算,进而得出更为确切的联轴器强度计算公式。 Crane coupling fatigue, strength calculation has been described in many literatures. Among them, the formulas for calculating the strength of the coupling mainly controlled by strength are even different. In this way, we can easily ask a series of questions: Which formula should be used to calculate it? Does the formula have their own deficiencies? Are they calculated in the same way? I think answering these questions must have the correct load calculation, And then come to a more precise calculation formula of coupling strength.
