Method for keeping damping of rotating shaft

The invention relates to the technical field of rotating shaft damping keeping, in particular to a rotating shaft damping keeping method which comprises the following steps: adopting a pair of rotating shafts, namely a first rotating shaft and a second rotating shaft; a rotating shaft plane is radially machined on the inner wall of the through hole of the second rotating shaft; a section of screw rod plane is machined at the end part of the fastening screw rod; the fastening screw sequentially penetrates through the first rotating shaft, the friction gasket and the second rotating shaft and is fastened through the lock nut, and the screw plane of the fastening screw is attached to the rotating shaft plane on the second rotating shaft. The screw rod and the second rotating shaft are each provided with a plane used for matching, looseness among the nut, the screw rod and the second rotating shaft is prevented, damping of the rotating shafts can be effectively kept, and the method does not need to add other part
