Embodiment 1

[0021] Put the styrene-butadiene rubber 1 into the mold and vulcanize the bearing surface layer 2, then wrap the bearing surface layer 2 around the polyhedral mold core 4 to form a cylinder, pass the glass fiber 5 on the wire wheel 6 through the dipping wheel 8, The epoxy resin 7 is completely infiltrated with the glass fiber 5, and the infiltrated glass fiber 5 is wound on the outer surface of the bearing surface layer 2 through the traction wheel 9 to form a composite material bearing jacket 10. When the thickness of the fiber layer reaches the required thickness, Stop the winding, cure the product at 60°C for 24 hours, take out the polyhedral mold core 4, and obtain the composite material-backed water-lubricated rubber bearing of the present invention. The resulting bearing dimensions are Inner diameter size error ± 0.15mm.

Embodiment 2

[0023] According to the method of Example 1, but using nitrile rubber instead of styrene-butadiene rubber to prepare the rubber surface layer, and then prepare the composite material backing water-lubricated rubber bearing of the present invention. The resulting bearing dimensions are Inner diameter size error ± 0.1mm.

Embodiment 3

[0025] According to the method of Example 1, but using polyurethane rubber instead of styrene-butadiene rubber to prepare the rubber surface layer, and then prepare the composite material-backed water-lubricated rubber bearing of the present invention. The resulting bearing dimensions are Inner diameter size error ± 0.2mm.

Abstract

The invention discloses a composite material backing water-lubricated rubber bearing and a preparation method thereof, belongs to the technical field of water-lubricated bearings, and solves the problems that large-size and high-precision water-lubricated bearings are difficult to manufacture at the same time in the prior art and the product cost is high. The composite material backing water-lubricated rubber bearing comprises a bearing outer sleeve (10) and a rubber surface layer (2), wherein the bearing outer sleeve (10) is prepared by winding glass fiber (5) presoaked with epoxy resin (7) onto the rubber surface layer (2), curing and forming. According to the invention, the composite material is used instead of yellow brass as the water-lubricated bearing outer sleeve, so that large quantities of noble metal materials are saved and the cost of the water-lubricated bearing product is reduced; and as the curing and forming technology is adopted and the process is simple, the composite material backing water-lubricated rubber bearing has the advantages of large size, high precision and easiness in processing.

Description

technical field [0001] The invention belongs to the technical field of water lubricated bearings, and in particular relates to a composite material backed water lubricated rubber bearing and a preparation method thereof. Background technique [0002] Water-lubricated rubber bearings use water as a lubricant. Compared with traditional oil-lubricated bearings, they have the advantages of no pollution, low energy consumption, low friction coefficient, and low price. Therefore, they are widely used in the field of ships. Water-lubricated rubber bearings generally consist of a bearing housing and a bearing surface. In order to ensure the corrosion resistance of the bearing, the outer shell of the bearing is usually made of expensive metal brass, and the surface layer of the bearing is mostly made of rubber material. The structure of water-lubricated bearings mainly includes integral and slat-type structures. The overall structure vulcanizes rubber directly on the inner surface o...
