In one implementation, the manner of attaching and fastening the elastic body 2 and the outer cover 1 may also be: the elastic body 2 is arranged inside the outer cover 1 and is bonded and fastened with the inner surface of the outer cover 1 through an adhesive.

Similarly, the embodiment of fastening by adopting the adhesive is convenient to operate and saves cost.

It should be noted that, when the inner ring 3 and the elastic body 2 are attached and fastened by using a binder, the elastic body 2 and the outer cover 1 are attached and fastened by using a binder, and the second clip 34 and the slot are assembled and fastened; when the inner ring 3 and the elastic body 2 are attached and fastened in a way of assembling and fastening the first blocking portion 33 and the blocking groove, the elastic body 2 and the outer cover 1 are attached and fastened in a way of adhering and fastening by using an adhesive, or the second blocking portion 34 and the blocking groove are assembled and fastened.

After the mechanism using the vibration damping device is installed in cooperation with the vibration damping device, at least two screws may be used to connect the screw holes of the cover 1 through the holes of the sealing cover plate 4.

The embodiment adopts a threaded connection mode to ensure that the outer cover 1 and the sealing cover plate 4 are simply and stably fastened.

It is worth mentioning that after the mechanism using the vibration damper is installed in cooperation with the vibration damper, the edge of the sealing cover plate 4 may be welded to the portion of the outer cover 1 to be attached, so as to achieve the purpose of fastening.

In one implementation, the elastic body 2 may be made of a material having elastic properties, such as rubber.

In order to reduce the heat generated by the long-term operation of the mechanism integrating the vibration damping device of the embodiment of the present invention and prolong the service life of the mechanism, in one implementation, heat dissipation holes may be provided on the sealing surface of the housing 1, and heat dissipation fins 41 may also be provided on the outer surface of the side wall of the housing 1 along the circumferential direction; the radiating fins 41 on the side wall of the housing 1 further achieve the purpose of heat dissipation by increasing the heat dissipation area, and meanwhile, the radiating fins 41 on the side wall of the housing 1 can also achieve the purpose of stabilizing vibration by increasing the moment of inertia. At least one heat dissipation groove penetrating through the plate surface can be arranged on the plate surface of the sealing cover plate 4, so that the purpose of heat dissipation is further achieved.
