Z575型立式钻床在使用中有三个部位经常坏,停修时间长,影响生产。为此,我们结合维修进行了改进,彻底解决了问题,取得了显著的经济效益。现介绍如下: 1.如附图a所示,快速电机轴1和与其相连的传动轴4容易从A、B处断裂,几乎每月都要换。经过分析,其断裂原因是:电机轴 1伸出部分直 Z575 vertical drilling machine in use, there are three parts often bad, long repair time, affecting production. To this end, we have improved with the maintenance, solve the problem completely and achieved significant economic benefits. Now as follows: 1. As shown in Figure a, fast motor shaft 1 and its connected drive shaft 4 easy to break from A, B, almost every month to change. After analysis, the reason for the fracture is: motor shaft 1 straight part out
