在机电设备检修工作中,时常可以遇到装有滚珠轴承的轴,因为使用日久磨损或者由于制造时配合精度不高而产生松动。解决这个松动问题办法很多,譬如可以用轴上镶套的办法,但是轴上有和锁紧螺母相配的螺纹时,就没法镶套了,另外可以用焊补轴颈的办法,这种方法的缺点是,轴受高温后会弯曲,弯曲后很难处理,同时轴的焊补部分会变脆,容易断裂。在大跃 In the mechanical and electrical equipment maintenance work, often encounter the shaft with ball bearings, wear and tear due to the use of time or due to manufacturing with low precision and produce loosening. There are many ways to solve this loosening problem, for example, the shaft can be set way, but the shaft and the lock nut to match the thread, it can not be set, and the other can be used to repair the journal approach, this method The disadvantage is that the shaft will be bent after high temperature, it is difficult to handle after bending, at the same time the welding part of the shaft will become brittle and easy to break.
