Abstract
The utility model discloses an embedding-type bearing sprayed with a lubrication layer, aiming at providing the embedding-type bearing sprayed with lubrication layer which has simple structure, large bearing capability and no forepart abrasion or hinge-axis phenomena in applied initial stage. The utility model includes a round shaft sleeve or a slab made of metal; a sliding surface is drilled with through holes or blind holes distributed according to a certain rule; the through holes or blind holes are embedded with a solid lubricant aligned with the sliding surface. The utility model is characterized in that the sliding surface is coated with a layer of lubrication membrane. After the sliding surface is coated with a layer of lubrication membrane, the utility model has the lubrication function by the lubrication membrane in the running-in initial stage and avoids the occlusion or forepart abrasion phenomena in the running-in initial stage caused by non-sufficient lubrication.
Description
Technical field
The utility model relates to sliding bearing, relates in particular to a kind of inlaying bearing that is coated with lubricating layer.
Background technique
At present, a kind of title JDB profile shaft that has of producing on the market holds, and is that inlaid solid lubrication agent in the hole again forms through cutting then in metallic surface boring.In use, by the motion of friction pair, the solid lubricant particulate that will inlay takes whole working surface to, thus lubricate.But it has a shortcoming, because the solid lubricant of inlaying does not also fully cover whole working surface, occurs the phenomenon of axle and bearing seizure or premature wear at the break-in initial stage easily.
The model utility content
The purpose of this utility model be to provide a kind of simple in structure, bearing capacity big, the inlaying bearing that is coated with lubricating layer of premature wear or " stinging axle " phenomenon can not take place at the use initial stage.
The technological scheme that is coated with the inlaying bearing of lubricating layer in order to achieve the above object is: comprise the round sleeve or the flat board that are made of metal, be drilled with through hole or the blind hole that distributes according to certain rules at slidingsurface, in the hole, be inlaid with the solid lubricant concordant with slidingsurface.It is characterized in that described slidingsurface is coated with one deck lubricating film.
The inlaying bearing that is coated with lubricating layer according to the such scheme manufacturing, after the slidingsurface of bearing applies one deck lubricating film, can the break-in initial stage by the lubricating film lubricate, avoid the break-in initial stage because of lubricated insufficient phenomenon that interlock or premature wear take place.
Description of drawings
Fig. 1 is the structural representation of plane sliding bearing that is coated with the inlaying bearing of lubricating layer;
Fig. 2 is the A-A profile of Fig. 1;
Fig. 3 is the plan view of axle sleeve type sliding bearing that is coated with the inlaying bearing of lubricating layer;
Wherein: 1, steel plate; 2, aluminium brass layer; 3, through hole; 4, solid lubricant; 5, lubricating film; 6, axle sleeve; 7, hole.
Embodiment
The utility model will be further described below in conjunction with drawings and Examples.
Embodiment 1: according to the specification of plane sliding bearing at a surperficial sintering of low carbon steel plate 1 or be cast with the aluminium brass layer 2 of ZCuZn26Al4Fe3Mn3, make the double metallic composite material flat board of steel and copper, be shaped on evenly in a row circular through hole 3 on the surface of aluminium brass layer 2, also can be made into blind hole, and make the circular gross area of each through hole 3 account for bimetal slide plate rectangular area 20% to 35% between as shown in Figure 1.In through hole 3, be inlaid with molybdenum disulfide again and make cylindrical solid lubricant 4, the surface of fine finishing slide plate again, make the bimetal sled surface concordant with cylindrical solid lubricant 4 end faces and reach the technical requirements of slide plate, be coated with one deck lubricating film 5 as shown in Figure 2 at slidingsurface again, this lubricating film 5 can be plastics and/or graphite and/or molybdenum disulfide, does not also get rid of and uses other solid lubricant.The material of used flat board can also be Cuprum alloy or cast iron or steel, the mixture of the also available graphite of solid lubricant 4 or graphite and molybdenum disulfide or molybdenum disulfide and plumbous mixture.
Embodiment 2: the specification according to the axle sleeve type sliding bearing is made tubular axle sleeve 6 with the Bearing Steel of GCr15, and stay certain machining allowance, on the circumferential surface of axle sleeve 6, be drilled with hole 7 equally distributed and that connect with axle sleeve 6 inside and outside walls, and make the gross area in hole 7 account for 25% of the axle sleeve 1 internal surface gross area.Axle sleeve 6 is through Quenching Treatment, improves hardness, is inlaid with in hole 7 with graphite and makes cylindrical solid lubricant 4, and the inside and outside circle of fine finishing axle sleeve 6 is to requiring again, and the lubricating film 5 that is coated with one deck molybdenum disulfide at slidingsurface as shown in Figure 3 again.
Claims (5)
1. be coated with the inlaying bearing of lubricating layer, comprise the round sleeve or the flat board that are made of metal, be drilled with through hole or the blind hole that distributes according to certain rules, in the hole, be inlaid with the solid lubricant concordant with slidingsurface at slidingsurface.It is characterized in that described slidingsurface is coated with one deck lubricating film.
2. the inlaying bearing that is coated with lubricating layer according to claim 1 is characterized in that described solid lubricant is graphite or molybdenum disulfide or graphite and molybdenum disulfide or molybdenum disulfide and plumbous mixture.
3. the inlaying bearing that is coated with lubricating layer according to claim 1, the lubricating film that it is characterized in that described coating are plastics and/or graphite and/or molybdenum disulfide.
4. the inlaying bearing that is coated with lubricating layer according to claim 1, the gross area that it is characterized in that described through hole or blind hole account for metal surface, place, the hole gross area 20% to 35% between.
5. the inlaying bearing that is coated with lubricating layer according to claim 1 is characterized in that described metal is meant double metallic composite material or the cast iron or the steel of Cuprum alloy or steel and copper.
