Marine thrust bearing energy dissipation damper and assembling method thereof

Abstract

The invention discloses a marine thrust bearing energy dissipation damper and an assembling method thereof. The marine thrust bearing energy dissipation damper comprises a bottom plate, a housing anda stressed block, wherein a second sealed working cavity is formed between the bottom plate and the housing; an energy dissipation component and a damping liquid are arranged in the second sealed working cavity; and the energy dissipation component comprises a first thrust piston, a second thrust piston, a piston cylinder, a thrust connecting rod and a porous damping plate. According to the marinethrust bearing energy dissipation damper and the assembling method thereof, the damping liquid is used as an energy dissipation medium of the damper, so that rigid collision generated by longitudinalvibration is better avoided, and the shafting is more stable. By adopting modular design and manufacturing, the structure is compact, the installation space and the structural load of a thrust bearing are reduced, the weight is lighter, the manufacturing cost is greatly reduced on the premise of improving the stability, and therefore the thrust bearing is economical and energy-saving, and has higher vibration suppression efficiency and higher parameter stability.

Description

technical field [0001] The invention relates to an energy dissipation damper for a marine thrust bearing and an assembly method thereof, in particular to an energy dissipation damper for a thrust bearing for a marine with a porous damping plate, which is used for consuming the energy of the longitudinal vibration of the shafting, and belongs to the shafting damper of a ship. field of vibration technology. Background technique [0002] Ship propulsion shafting generally consists of propellers, stern shafts, intermediate shafts, sliding bearings, thrust shafts, thrust bearings, elastic couplings, transmissions and diesel engines. The uneven wake field at the ship's stern shaft is the direct cause of the longitudinal alternating pulsating excitation force at the blade. The propeller alternating longitudinal force usually acts on the hull in two forms, causing hull vibration and underwater radiated noise, one is directly transmitted to the surface of the hull through the stern ...

Problems solved by technology

However, the resonant converter needs to be externally connected to the thrust bearing, which is not only difficult to process and install, but also the actual working environment of the cabin is complex, and there are many factors that affect the safe operation of external components. Once an accident occurs, it will affect the normal operation of the ship. Therefore, the engineering application value Subject to certain restrictions
