在机器维修过程中,有时稍有不慎,会将螺母等物掉进齿轮箱等的壳体内,虽然眼睛看得到,但用手却很难取出。此时,可用一块稍大的磁铁或永磁式交流发电机的转子,吸住一直径和长度适宜的元钢的一端,将元钢的另一端伸入箱体内(元钢不得与箱体边缘和箱体内的轴、齿轮等物相擦),触到掉进去的螺母等小铁件物,此物即会吸住。这时,只要抓稳磁铁和元钢,轻轻地抽出元钢,螺母之类的小铁件物就能吸出来。
In the machine maintenance process, sometimes a little careless, will fall into the nuts and other gear box and other housing, although the eyes can see, but it is difficult to remove with his hand. At this point, a larger magnet or permanent magnet alternator rotor may be used to suck one end of a steel rod of suitable diameter and length, and extend the other end of the elemental steel into the box body And the box body axis, gears and other objects rub), touch fell into the nuts and other small iron objects, this thing will suck. At this time, just grasp the magnet and the elemental steel, gently pull out the yuan steel, nuts and the like small pieces of iron can be sucked out.
