The invention relates to the technical field of ship vibration reduction, in particular to a torsional vibration reduction assembly suitable for a yacht transmission system. An engine output shaft of a yacht engine is connected with a transmission device outside a ship board through a vibration reduction shaft, and the yacht engine is fixed to a bottom plate in the ship board through an engine support; a multi-stage torsional vibration reduction assembly is arranged in the vibration reduction shaft and further comprises a first-stage vibration reduction assembly fixedly connected with the engine output shaft, a second-stage vibration reduction assembly is arranged on the outer side of the first-stage vibration reduction assembly in the circumferential direction in a sleeving mode, and the vibration reduction shaft is arranged on the outer side of the second-stage vibration reduction assembly in the circumferential direction in a sleeving mode. Through the multi-stage torsional vibration damping assembly, the output of the engine can be guaranteed, and meanwhile the damping amplitude is improved.

    本发明涉及船舶减振技术领域,具体为一种适用于游艇传动系统的扭振减振组件,游艇发动机的发动机输出轴通过减振轴与船舷外的传动装置连接,所述游艇发动机通过发动机支座固定在船舷内的底板上,所述减振轴中设置有多级扭振减振组件,所述多级扭振减振组件还包括与所述发动机输出轴固定连接的一级减振组件,所述一级减振组件的周向外侧套设有二级减振组件,所述二级减振组件的周向外侧套设所述减振轴,通过多级的扭振减震组件能够保证发动机输出的同时提高减震幅度。
