The invention belongs to the technical field of ship cabins, and discloses a ship cabin vibration and noise reduction assembly which comprises a ship cabin shell. The ventilation pipelines are arranged on the two sides of the front end of the ship cabin shell; the ventilation fan blades are movably mounted in the ventilation pipeline; the noise reduction assembly comprises a lubricating noise reduction cavity. According to the technical scheme, the lubricating oil storage barrel, the noise reduction rubber block and the power assembly are arranged, and the power assembly can drive the shielding assembly to remove blocking between the lubricating oil storage barrel and the lubricating noise reduction cavity; a part of gas in the noise reduction rubber block enters the lubricating oil storage barrel through the ventilation pipeline, the driving piston block can be pushed to drive lubricating oil in the lubricating oil storage barrel to be guided into the lubricating noise reduction cavity, so that the part, making contact with the ventilation pipeline, of the ventilation fan blade is smoothly lubricated, the friction force is reduced, and then the noise reduction purpose is achieved. And the comfort of passengers is smoothly improved.

    本发明属于船舶舱室技术领域,且公开了一种船舶舱室减振降噪组件,包括船舶舱室壳体;通风管道,设置于船舶舱室壳体前端的两侧;通风扇叶,活动安装于通风管道的内部;降噪组件包括润滑降噪腔。上述技术方案通过设置润滑油存储筒、降噪橡胶块和动力组件,通过动力组件可驱动遮挡组件解除对润滑油存储筒和润滑降噪腔之间的封堵,之后当通风扇叶整体旋转使得通风管道整体产生振动,使得降噪橡胶块内的部分气体通过通气管道进入至润滑油存储筒,可推动驱动活塞块带动润滑油存储筒内润滑油导入至润滑降噪腔内,以便顺利对通风扇叶与通风管道接触的部分进行润滑,从而降低摩擦力,进而实现降噪的目的,顺利提高乘客的舒适度。
