Embodiment 1

[0035] The silicone rubber with a hardness of 65 shore D was kneaded at room temperature for 10 min with a double-roll mill to obtain a sheet material with a thickness of 3 mm and a width of 15 mm;

[0036] Coat the core of the mold, the base of the mold and the upper cover of the mold with silicone oil release agent, preheat for 40 minutes at 165 °C, wrap the above-mentioned silicone rubber tightly around the core of the mold, and place it on the base of the mold , cover the upper cover of the mold, the guide post 5 and the screw hole 1 match each other, the gas in the cavity is discharged through the vent hole 2, the excess compounded rubber is extruded out of the mold through the discharge port 3, and fixed through the gap 4 Shaft core, then put the mold into the vulcanizer, vulcanize at 180°C and 10 MPa pressure for 60 minutes, open the mold, take out the shaft core, demould, and get the blank product of water-lubricated bearing bush;

[0037]The blank product of the above...

Embodiment 2

[0039] The acrylonitrile-butadiene rubber that hardness is 60 shore D utilizes double roller open mill to knead 10 min at normal temperature, obtains 3 mm thickness, the sheet material of 15 mm width;

[0040] Coat the core of the mold, the base of the mold and the upper cover of the mold with silicone oil, preheat for 40 minutes at 120 °C, wind the nitrile rubber after mixing tightly on the core of the mold, place it on the base of the mold, cover it On the upper mold cover, the guide post 5 and the screw hole 1 match each other, the gas in the cavity is discharged through the vent hole 2, the excess compound rubber is extruded out of the mold through the discharge port 3, and the shaft core is fixed through the gap 4 , then put the mold into the vulcanizer, vulcanize at 120°C and 10 MPa pressure for 130 minutes, open the mold, take out the shaft core, demould, and obtain the blank product of the water-lubricated bearing bush;

[0041] The above-mentioned water-lubricated bea...

Embodiment 3

[0043] The fluororubber with a hardness of 62 shore D was kneaded at room temperature for 10 min with a double-roller open mill to obtain a sheet material with a thickness of 3 mm and a width of 15 mm;

[0044] Coat the core of the mold shaft, the base of the mold and the upper cover of the mold with silicone oil, preheat for 40 minutes at 180 °C, wrap the above mixed fluororubber tightly around the core of the mold, place it on the base of the mold, and cover it The upper cover of the mold, the guide post 5 and the screw hole 1 match each other, the gas in the cavity is discharged through the vent hole 2, the excess compounded rubber is extruded out of the mold through the discharge port 3, and the shaft core is fixed through the gap 4, Then put the mold into the vulcanizer, vulcanize at 165°C and 10 MPa pressure for 20 minutes, open the mold, take out the shaft core, demould, and obtain the blank product of the water-lubricated bearing bush;

Abstract

A manufacturing method of a water lubricated bearing taking hard rubber as a liner belongs to the field of a manufacturing method of a bearing. The problem that the existing manufacturing method of the rubber bearing is inapplicable for the water lubricated bearing taking the high-hardness rubber as the liner is solved. The method comprises the following steps of: mixing and milling the hard rubber by a double-roller mill, winding the mixed and milled hard rubber on a central spindle, arranging the mixed and milled hard rubber on a mold base, covering an upper cover of the mold on the mixed and milled hard rubber, arranging the mold on a vulcanizing machine, vulcanizing for 20-30min under the condition of 120 DEG C to 180 DEG C, opening the mold, de-molding, obtaining the water lubricated bearing lining blank product, performing machine finishing to the water lubricated bearing lining blank product, then arranging the product in a bearing sleeve, and obtaining the water lubricated bearing taking the hard rubber as the liner. Aiming at the defect that the hard rubber is hard to flow, a novel sleeve mold and the vulcanizing technique are used for preparing the water lubricated bearing; and the preparation method is simple, and high in efficiency, and is beneficial for mass production.

Description

technical field [0001] The invention relates to the field of bearing manufacturing methods, in particular to a manufacturing method of a hard rubber-lined water-lubricated bearing. Background technique [0002] Water-lubricated bearings are widely used supporting parts in machines. A wide variety of sliding bearings have a wide range of applications. Modern rotating machinery requires bearings to have good load-carrying capacity, long life and high reliability. Water-lubricated bearings are composed of outer metal sleeves (steel or copper) and inner-layer bushings. Among the bearing lining materials, materials that have been used or are still used to make water-lubricated bearings in China include iron pear wood and cloth bakelite. , rubber, plastics, ceramics, graphite products, metals, alloys and metal plastics, etc. Among them, iron plow wood, metal materials, etc. are expensive, and the use effect is poor; both plastic bearings and ceramic bearings have good running per...
