Specific embodiment
Specifically illustrate embodiments of the present invention with reference to the accompanying drawing, attached drawing is only for reference and illustrates use, does not constitute pair
The limitation of the invention patent protection scope.
As shown in Fig. 1-1,1-2,1-3 and Fig. 6-1,6-2, the present embodiment provides a kind of Damping rotation shafts 100, including are equipped with solid
The main shaft 1 of fixed end 10, rotation fixing sleeve 2, lock-nut 3, rotation fixing sleeve 2 are placed on the main shaft 1, lock-nut 3 with
The connection of 1 end thread of main shaft；It is equipped with frictional damping washer 4 between rotation fixing sleeve 2 and the fixing end 10 of main shaft 1, is rotating
Lacating block 5 and a pair of of bowl-type elasticity washer 6 are equipped between fixing sleeve 2 and lock-nut 3.
In the present embodiment, Damping rotation shaft 100 is metal Damping rotation shaft structure, wherein main shaft 1, rotation fixing sleeve 2, locking
Nut 3 and frictional damping washer 4, lacating block 5 and a pair of of bowl-type elasticity washer 6 are metal structure.
As shown in Fig. 2-1,2-2,2-3 and Fig. 3-1,3-2,3-3, in the present embodiment, the fixing end 10 of the main shaft 1 with
The surface for rotating fixing sleeve 2 is equipped with gear hobbing pumping slot structure.
