Abstract
The utility model relates to a water lubricate carborundum radial bearing comprising a positioning bolt, a carborundum radial bearing bushing , a carborundum bushing, a shaft, a positioning nut, a baffle, a bearing base and water, etc. The carborundum radial bearing bushing is positioned inside the bearing base. The bearing bushing and the bearing base are provided with a bolt for positioning at the same place. The baffle suited on the right end surface of the bearing is fixed on the bearing base end surface via the bolt. The carborundum radial bearing bushing is matching with radial and the positioning nut is matching with a shaft screw and its inner end surface is pressed on the end surface of the carborundum radial bearing bushing. When the bearing is working, water will be used as lubricate. The utility model makes the improvement via bushing material and shaft bushing structure so as to perfect the bearing performance. In addition, the utility model is assembled by adopting these components attached with carborundum material and achieves active and beneficial technical effect.
Description
Technical field
The utility model relates to the water lubrication radial bearing, and definite saying so relates to the horizontal machine water lubrication radial bearing in the particular surroundingss such as radiation, corrosion.
Technical background
Water lubriucated bearing is some special equipments such as centrifugal pump, corrodes the critical component of pump, compressor, magnetic force driving pump, canned motorpump, Submerged Motor Pumps etc. that its bearing capacity and wear-out life are the key factors of this bearing reliable operation of restriction.Bearing material will have high-temperature oxidation resistance and decay resistance preferably, in China, water lubriucated bearing adopts graphite material mostly, though this material has the advantage of selflubricating, but wear no resistance, under the normal operating condition, still rely on the hydrldynamic pressure lubrication carrying mostly, so just limited the bearing capacity of this bearing greatly.After the bearing specific pressure strengthened, the life-span was limited.Adopting new material and preferred fastness is the effective way that addresses this problem.
Summary of the invention
Goal of the invention of the present utility model provides the good water lubrication silicon carbide radial bearing of a kind of self lubricity, conduction, heat conduction, anti-thermal shock and hot strength.The utility model is a kind of water lubrication silicon carbide radial bearing, comprise positioning screwn, silicon carbide radial bearing watt, the silicon carbide axle sleeve, axle, setscrew nut, baffle plate, bearing support and water etc., the silicon carbide radial bearing watt is sleeved in the bearing support, bearing liner, the equipped screw of bearing support same position location, the baffle plate that the bearing right side is sleeved on the axle has screw on the bearing support end face, silicon carbide axle sleeve and diameter of axle transition fit, and setscrew nut cooperates with male thread, its interior edge face is fitted on the silicon carbide axle sleeve end face, uses water as oiling agent during bearing working.The related position of the utility model is the horizontal machine water lubrication radial bearing in the environment such as radiation, corrosion, by the improvement of tiling material and axle sleeve structure, reaches the purpose of improving bearing performance.Structure of the present utility model has adopted these parts that have silicon carbide material to assemble, positive beneficial technical effects in obtaining.

Embodiment
Model utility as shown in Figure 1 is a kind of water lubrication silicon carbide radial bearing, positioning screwn 1, silicon carbide radial bearing watts 2, silicon carbide axle sleeve 3, axle 4, setscrew nut 5, baffle plate 6, bearing support 7 and water 8 etc., silicon carbide radial bearing watts 2 is sleeved in the bearing support 7, bearing liner 2, the equipped screw of bearing support 7 same positions location, the baffle plate 6 that the bearing right side is sleeved on the axle 4 has screw on bearing support 7 end faces, silicon carbide axle sleeve 3 and the diameter of axle 4 transition fit, setscrew nut 5 and axle 4 screw-thread fit, its interior edge face is fitted on silicon carbide axle sleeve 3 end faces, and water 8 is made oiling agent during bearing working.The friction pair of bearing liner and axle sleeve is carbofrax material.
Carbofrax material is a kind of new material, and it has the good advantage of self lubricity, conduction, heat conduction, anti-thermal shock and hot strength, has high hardness, advantage such as wear-resistant, anti-oxidant, corrosion-resistant again, is a kind of high performance high-abrasive material.The friction mechanism of silicon carbide radial bearing is different with the hydrodynamic lubrication bearing, and it mainly relies on the wear resistance and the chemical reaction film under water base condition of carbofrax material.Therefore, the silicon carbide radial bearing under the aqueous medium condition, advantage such as it is big to have bearing capacity, wear-resistant, high temperature resistant.
Water lubrication silicon carbide radial bearing, related position is the horizontal machine water lubrication radial bearing in the particular surroundingss such as radiation, corrosion, by the improvement of tiling material and material, axle sleeve, reaches the purpose of improving bearing performance.
