The invention provides a vibration and noise reduction device, lateral propulsion equipment and a ship, and relates to the technical field of ships. The vibration and noise reduction device comprisesan inner sleeve and an outer sleeve; the inner sleeve is sleeved with the outer sleeve, and the inner sleeve is connected with the outer sleeve. A vibration source is arranged in the inner sleeve. Dueto the arrangement of the vibration and noise reduction device, vibration and noise generated during operation of a propeller can be reduced fundamentally, vibration and noise reduction materials donot need to be added to a deck and a bulkhead plate, or the perimeter structure of a cabin does not need to be modified, and the workload and the construction cost are reduced.

    本发明提供了一种减振降噪装置及侧向推进设备及船舶,涉及船舶的技术领域,减振降噪装置包括内套筒和外套筒;所述外套筒套设在所述内套筒的外部,且所述内套筒和所述外套筒连接;所述内套筒中用于设置振动源。减振降噪装置的设置,能够从根源上降低螺旋桨运行时产生的振动和噪声,无需在甲板和舱壁板上增加的减振降噪材料,或者修改舱室周界结构,降低了工作量和建造成本。
