Closed type water-lubricating bearing system

Abstract

The invention discloses a sealed type water-lubricating bearing system. The sealed type water-lubricating bearing system comprises a shaft sleeve assembly and water sealing bearings which support a tail shaft, wherein the inner peripheries of the water sealing bearings and the outer periphery of the tail shaft are in water lubrication; the front sealing assembly is used for sealing one group of water sealing bearings at one end close to a shaft coupler, and is used for preventing circulating fresh water from leaking towards the shaft coupler; a rear sealing assembly is used for sealing anothergroup of water sealing bearings, close to one end of a propeller, and is used for preventing circulating fresh water from leaking towards the propeller, and preventing seawater from passing through the rear sealing assembly; and the closed type water-lubricating bearing system is further provided with a water supply system for forming flowing fresh water circulation between the shaft sleeve assembly and the water sealing bearings, and cooling the front sealing assembly and the rear sealing assembly. The closed type water-lubricating bearing system provided by the invention is more perfect inintegral function, can provide good sealing requirements and cooling performances during operation, and facilities better maintenance and operation by judging a flowing condition of fresh water through a control system.

Description

technical field [0001] The invention relates to the field of bearing system and technology, in particular to a closed water lubricated bearing system. Background technique [0002] Under the current trend, due to the quality of water-lubricated bearings, water-lubricated bearings generally have a jacket and a polymer composite bearing. In terms of manufacturing materials, the bearing jacket is made of composite materials. The bearing surface layer is rubber material, and the composite material is glass fiber reinforced epoxy. resin. Therefore, the breakthrough in materials saves the manufacturing cost of precious metals in the past. Water-lubricated bearings made of new materials are light in weight, high in precision, and easy to process and manufacture. Therefore, the application range of water-lubricated bearings will be more extensive in the future . [0003] In the current way, the application of water-lubricated bearings is divided into closed water-lubricated system...

AI Technical Summary

Problems solved by technology

[0005] The present invention aims to solve the technical problems that the functions of the water-lubricated bearing system in the prior art are not perfect enough, the sealing performance and cooling effect are poor, the failure cannot be judged in time, and the application of the water-lubricated bearing is restricted, and a closed water-lubricated bearing system is provided.
