在飞机的重要结构连接部位,螺栓不能拧得过紧或过松。不然,该部位的所有螺栓不能均匀受力,拧得过紧,易损伤结构,甚至螺栓断裂;拧得过松,使用中会松动。因此,要求这些螺栓都要拧到规定的力矩范围内。一般使用的普通扳手,螺栓的拧紧程度全靠手的感觉,感到已很“吃劲”了,就算拧紧了。这种手上的“吃劲”感觉,因人而异,差别较大。所以,产品图纸上规定力矩拧紧的螺
Bolts can not be over-tightened or loosened at the important structural connections of the aircraft. Otherwise, all the bolts in this part can not be evenly pressed, tightened too much, the structure is damaged easily, or even the bolts break; if the screw is too loose, it will loosen in use. Therefore, these bolts are required to be screwed to the specified torque range. General use of the ordinary wrench, bolt tightening degree depends entirely on the feeling of the hand, I feel very “hard”, and even tightened. This kind of “strenuous” feeling in the hand can vary from person to person. Therefore, the product drawings on the provisions of the tightening torque screw
