The invention relates to the technical field of ship long shafting, and discloses a ship long shafting longitudinal damping device which comprises a ship shafting, a damping mechanism and an adjusting mechanism are arranged below the ship shafting, and the damping mechanism is located on the surface of the adjusting mechanism; the vibration reduction mechanism comprises a supporting assembly and a vibration reduction assembly. The damping assembly is located on the surface of the supporting assembly. Different positions of the ship shafting are supported by two supporting frames and two connecting ring plates through the vibration reduction mechanism and the supporting assembly, so that the vibration reduction positions of the ship shafting are increased, the ship shafting makes contact with the connecting ring plates, when the ship shafting vibrates, the vibration reduction frequency band obtained by the connecting ring plates is wide, high, medium and low frequency vibration of the ship shafting is well considered, and the vibration reduction effect is good. The device is simple in structure and suitable for being applied to complex vibration working conditions, the vibration reduction assembly achieves the vibration reduction effect on the supporting plate through the damping performance of the damper and the acting force of the spring, and therefore the vibration reduction effect on the ship shafting is achieved, and the longitudinal vibration reduction effect of the device on the ship long shafting is improved.
