Meanwhile, the bearing is positioned between the rotation shaft 210 and the housing 100, and the inner ring of the bearing 230 is interference fit with the rotation shaft 210, and the inner ring of the bearing 230 is interference fit with the housing 100, so that sliding friction between the rotation shaft 210 and the housing 100 is converted into rolling friction between the inner ring and the outer ring of the bearing 230 through the bearing 230, and abrasion of the rotation shaft 210 and the housing 100 is reduced. The bearing 230 and the portion of the rotation shaft 210 that is interference-fitted with the inner ring of the bearing 230 form a heat-generating portion of the vibration exciter 200, and the cooling assembly 400 is used to guide the cooling liquid to the heat-generating portion. Wherein the cooling assembly 400 is used to guide the cooling fluid to the outer surface of the bearing 230 and the portion of the rotation shaft 210 that is interference-fitted with the bearing 230, it is understood that the cooling fluid only flows through the outer wall of the bearing mount to effect cooling of the bearing 230 through heat exchange with the outer surface of the bearing 230, and at the same time, the cooling fluid does not flow into the interior of the bearing 230 to avoid dilution of the grease within the bearing 230 by the cooling fluid.

The foregoing description is only of the preferred embodiments of the present utility model, and is not intended to limit the scope of the present utility model.
