[1]常用螺纹上紧方法 在重型机械的制造和维修中,我们经常会遇到将直径 M30以上的螺栓上紧的情况,这是一种艰难的工作。使用手控扳手、扭矩扳手等常见的扭紧工具,上紧一个 M30的螺栓就十分费力。如果要使一个 M125的螺栓产生 600kN的拉力,很显然采用直接人工上紧的方法
[1] Common thread tightening methods In the manufacture and maintenance of heavy machinery, we often encounter the tightening of bolts above M30 in diameter, which is a difficult task. Using manual torque wrenches, torque wrenches and other common tightening tools, tightening a M30 bolt is very laborious. If you want to make a M125 bolts produce 600kN tension, it is clear that the use of direct manual tightening method
