Abstract

The invention discloses a hydraulic-driven eight-foot thrust bearing base, comprising a shaft, a thrust bearing, a support assembly and a base, wherein the shaft passes through the thrust bearing; the support assembly comprises two actuator groups which are respectively and symmetrically distributed at two sides of the thrust bearing; each actuator group comprises four actuators, two upper part connecting blocks positioned at one side of the thrust bearing, and three lower part connecting blocks arranged on the base; an 'M'-shaped structure is formed by the actuators, the upper part connecting blocks and the lower part connecting blocks of each actuator group; the upper part connecting blocks, the lower part connecting blocks and the actuators are connected in a way of spherical hinge connection. The thrust bearing base provided by the invention is simple, efficient and flexible; after the design is adopted, the bearing load can be evenly distributed, the working performance of a shaft system is improved, the normal operation of the shaft system is guaranteed, and active and passive control can be also effectively carried out on the vibration of the shaft system.

Description

technical field [0001] The invention relates to the field of vibration reduction and noise reduction, in particular to a hydraulically driven eight-legged thrust bearing base. Background technique [0002] At present, the vibration reduction performance of ship equipment, as an important index to measure the comprehensive performance of modern ships, has attracted more and more attention. Excessive hull vibration can lead to fatigue damage to the hull structure, which will affect the normal operation of equipment and instruments on board, reduce accuracy and shorten service life; in addition, hull vibration and the cabin noise caused by it also affect the living comfort of crew and tourists. When people are in a vibrating environment for a long time, they will experience fatigue, affect work efficiency, and even endanger their health; at the same time, the vibration of ships will also bring a certain amount of marine noise environmental pollution. It is of great significanc...
