Problems solved by technology

[0003] Existing water-lubricated bearings for ships are mainly made of high-hardness materials (hardness above 45shor e D), such as a water-lubricated bearing with high bearing capacity and self-lubrication disclosed in CN103788623B. and high bearing capacity, but its flexibility and elasticity are poor. Under severe working conditions, such as navigating in inland rivers with poor water quality and sediment, the bearing has poor adaptability and large wear, which will produce abnormal noise and Vibration, unable to guarantee the safety of the ship

Abstract

The invention discloses a water-lubricated bearing material and a preparation method thereof, and belongs to the technical field of composite materials. The problem that an existing bearing has poor adaptability, large wear and the like under severe working conditions is solved. The water-lubricated bearing material is prepared from the following components in parts by weight: 20-30 parts of phenolic resin, 40-50 parts of nitrile rubber, 1-10 parts of graphene powder, 20-30 parts of basalt fiber, 0.1-1 part of a vulcanizing agent, 5-10 parts of a softener and 10-20 parts of a lubricating agent. The water-lubricated bearing material has the advantages of self-lubrication, high load-bearing, anti-fouling adhesion, green and pollution-free and the like through the synergistic action of the components, is suitable for working in internal navigation vessels with poor water quality and containing sediment, can work without water in short time, is low in noise, good in shock absorption effect, easy in formation of a water film and low in friction coefficient of water lubrication, and can directly and completely replace imported products.

Description

technical field [0001] The invention relates to the technical field of composite material preparation, in particular to a water-lubricated bearing material and a preparation method thereof. Background technique [0002] Bearings are an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce its friction coefficient during motion, and ensure its rotation accuracy. Commonly used bearings are sliding bearings, rolling bearings and joint bearings. Among them, sliding bearings refer to bearings that work under sliding friction. The lubrication methods used in sliding bearings mainly include water lubrication and oil lubrication. Oil leakage often occurs in oil lubrication, which pollutes the environment very much. Water-lubricated bearings use water as a lubricant. Compared with oil-lubricated bearings, they have the advantages of environmental protection and low energy consumption. They are widely used in ship...
