Abstract

The invention discloses a damping thrust bearing with a static water thrust self-balance function. The interior of the bearing is provided with two parts of parallel structures to jointly bear and balance thrust. A plurality of damping cylinders are arranged at the ahead end and the reverse end, and the damping cylinders at the ahead end are connected with a seawater pressure compensator on the outer side of a shell through a hydraulic pipeline. The part, at one ends of the damping cylinders at the ahead end, of the shell is provided with a lubricating oil inlet and outlet port in an up-down manner, and the thrust bearing achieves lubricating oil input and output according to the sea water pressure. Hydraulic oil in damping cylinder cavities in the reverse end directly communicates with lubricating oil in a damping thrust bearing cavity, and seawater pressure is not transmitted. The longitudinal vibration inherent frequency of a shaft system is reduced, a very good vibration isolationfunction is achieved for vibration within the paddle shaft system ahead and reverse full rotation speed range, and the damping thrust bearing is particularly suitable for a boosting shaft system for asubmersible vehicle.

Description

technical field [0001] The invention relates to a thrust bearing of a main shaft system of a submersible, in particular to a vibration-damping thrust bearing with hydrostatic thrust self-balancing function. Background technique [0002] The thrust bearing is an important piece of equipment in the propulsion system of a submersible. It transmits the torque in the positive and negative directions of the shafting to the propeller, and transmits the thrust and pull generated by the propeller to the hull to propel the submersible to sail. When the propeller rotates in the uneven flow field, there is a certain alternating component in the thrust generated by it, which forms a longitudinal excitation force, which generates a certain excitation on the shafting, and transmits it to the hull through the thrust bearing, causing the hull to vibrate and cause noise. , the vibration control of the propeller shaft system has always been the focus of the noise control of the submersible. ...
