Abstract
The invention discloses a sliding bearing with micro holes on the inner wall thereof, which is prepared through the steps of welding a bearing bush and a bearing lining the surface of which is uniformly provided with micro through holes; and then rolling, wherein the bearing lining is arranged in the bearing bush; the total area of the micro through holes on the surface of the bearing lining accounts for 10 to 20 percent of the surface area of the inner wall of the bearing lining; and the ratio of depth to diameter of the micro through holes on the surface of the bearing lining is 0.05 to 0.2. The sliding bearing disclosed by the invention has the advantages that the micro through holes on the bearing lining form micro grooves on the inner wall of the sliding bearing, and the micro grooves are used for storing the lubricating oil, and when sufficient lubricating oil is stored in the micro grooves, a dynamic pressure oil film is formed between the bearing bush of the sliding bearing and an axle journal rubbing pair, thereby reducing the rubbing wear; the elastic deformation of the bearing lining is enlarged, the rubbing pair is in an elastic hydrodynamic lubrication state, and the bearing is good in abrasion resistance and obvious in lubrication effect; and the bearing is simple in processing and easy to manufacture.
Description
Technical field
The present invention relates to sliding bearing, especially relate to a kind of sliding bearing of inner wall belt micropore.
Background technique
Sliding bearing is known in the art, and under the liquid lubrication condition, the undeveloped life of the lubricated oil content of slidingsurface directly contacts, and can also reduce frictional loss and surface abrasion greatly, and oil film also has certain vibration absorption ability.The antifriction material layer of surperficial top pouring within it forms bearing bush for the frictional property of improving the bearing shell surface.The bearing bush inwall must generate oil-bearing structure, and with storing lubricating oil, the wearing and tearing of reducing friction guarantee the life-span that sliding bearing lining-journal motion is secondary.More common bearing has bearings such as oil-impregnated bearing, plastic bearing, powder metallurgy on the market now, but exists problems such as cost is higher, manufacture difficulty is big, strength deficiency respectively.In view of the foregoing, will have a kind ofly be easy to make, wear resistance is good, intensity is high, the significant sliding bearing of lubrication effect.
Summary of the invention
The object of the present invention is to provide a kind of sliding bearing of inner wall belt micropore, change the more sliding bearing production method of traditional problem, in the hope of obtain a kind ofly to be easy to make, wear resistance is good, intensity is high, the significant sliding bearing of lubrication effect.
The technological scheme that the present invention adopts is:
The present invention is rolled into sliding bearing after being welded by bearing shell sheet and the surperficial bearing liner that has even micro through hole, and the surface has the bearing bush of even micro through hole in bearing shell inside.
The described bearing bush surface micro through hole regularity of distribution is that, equidistance parallel with bearing axis arranged or parallel adjacent two row equidistance with bearing axis, dislocation are arranged.
The described bearing bush surface micro through hole gross area is 10% ~ 20% of a bearing bush inner wall surface area.
Described bearing bush surface micro through hole aspect ratio scope is 0.05 ~ 0.2.
The beneficial effect that the present invention has is:
1, the bearing shell sheet of sliding bearing and the electricity consumption of bearing liner resistance weldering is welded together; Micropore on the bearing liner has promptly formed the little hole on the sliding bearing inwall; This cheats slightly and can be used for storing lubricating oil, and the lubricant oil oil mass is abundant, forms dynamic pressure oil film between sliding bearing-journal friction pair; The wearing and tearing of reducing friction guarantee life-span of kinematic pair.
When 2, the welding of bearing liner and bearing shell sheet was not firm, bearing liner resiliently deformable strengthened, and dynamic pressure oil film will be in the elastic hydrodynamic lubrication state between sliding bearing-journal friction pair, and the bearing wear resistance is good, and lubrication effect is obvious.
3, the little hole of bearing inner surface is evenly distributed regularly, and processing is simple; Bearing liner and bearing shell sheet join with the resistance welding form, are easy to make.
Description of drawings
Fig. 1 is the sliding bearing overall structure schematic representation of inner wall belt micropore;
Fig. 2 is the sliding bearing bearing bush that the inwall micropore is uniformly distributed with;
Fig. 3 is the sliding bearing bearing bush that the inwall micropore is dislocatedly distributed and is uniformly distributed with;
Among the figure: 1, bearing shell sheet, 2, the bearing liner.
Embodiment
To combine accompanying drawing and embodiment that the present invention is further described below.
As shown in Figure 1, a kind of sliding bearing of inner wall belt micropore is rolled into sliding bearing had bearing liner 2 welding of even micro through hole by bearing shell sheet 1 and surface after, and it is inner at bearing shell that the surface has the bearing liner 2 of even micro through hole.The bearing liner 2 surface micro through hole regularities of distribution are that, equidistance parallel with bearing axis arranged or parallel adjacent two row equidistance with bearing axis, dislocation are arranged, like Fig. 2, shown in Figure 3.Among the figure, the bearing liner 2 surface micro through hole gross areas are 19% of bearing liner 2 inner wall surface area, and bearing liner 2 surface micro through hole aspect ratio scopes are 0.1, and the inwall micro-pore diameter is 2mm, and pitch-row is 4mm.
The bearing shell sheet 1 of sliding bearing is welded together with bearing liner 2 usefulness resistance weldings; Micro through hole on the bearing liner 2 has promptly formed the little hole on the sliding bearing inwall; These micropores can be used for storing lubricating oil, and the lubricant oil oil mass is abundant, forms dynamic pressure oil film between sliding bearing-journal friction pair; The wearing and tearing of reducing friction guarantee life-span of kinematic pair.The bearing bush material uses Babbitt; Bearing shell adopts low carbon steel; Bearing bush is not firm with the axle sleeve welding or weld is tired contacted when losing efficacy, and the bearing bush resiliently deformable strengthens, and dynamic pressure oil film will be in the elastic hydrodynamic lubrication state between sliding bearing-journal friction pair; The bearing wear resistance is good, and lubrication effect is obvious.The little hole of bearing inner surface is evenly distributed regular, and the aperture size magnitude is millimeter, and perforating press can reach processing request, and processing is simple; Bearing bush and axle sleeve join with the resistance welding form, are easy to make.
Above-mentioned embodiment is used for the present invention that explains, rather than limits the invention, and in the protection domain of spirit of the present invention and claim, any modification and change to the present invention makes all fall into protection scope of the present invention.
