为了防止机床过载发生事故,立式或摇臂钻床都需正确调整保险离合器。由于我厂无专门测力器,离合器的调整只能凭经验进行,因此常因调整不当发生设备事故。现在,改用磅称和杠杆进行简单测量,效果较好。由图可见,压杆1的上端利用其锥度插入主动孔内,下端有一安装钢球的球窝,件2为钢球,在杠杆3放置钢球的地方也制有一球窝。件4是支承用角钢。调整时,机床用最低转速和最小进
In order to prevent machine overload accidents, vertical or radial drilling machine must be properly adjusted insurance clutch. As I plant without a special dynamometer, clutch adjustment can only be carried out by experience, so often due to improper adjustment of equipment accidents. Now, switch to pounds and leverage for simple measurements, the better. It can be seen from the figure that the upper end of the pressure rod 1 is inserted into the driving hole by using its taper, and the lower end is provided with a ball socket for mounting the steel ball. The steel ball is the component 2, and a ball socket is also formed where the steel ball is placed on the lever 3. Element 4 is supporting angle. Adjustment, the machine with the minimum speed and minimum advance
