Abstract
The utility model discloses a distributed sliding bearing with a bearing bush matrix surface provided with micro-pit oil pockets. A soft material layer is adhered to the bearing bush matrix surface of the sliding bearing; and multiple micro pits are symmetrically and uniformly distributed at the adhesion joint between the bearing bush matrix and the soft material layer so as to form multiple micro-pit oil pockets. According to the distributed sliding bearing, the micro-pit oil pockets which are uniformly distributed are arranged at the adhesion joint between the bearing bush matrix and the soft material layer, so that multiple convergent wedges can be formed in the bearing, the convergent wedges can be lubricated in the positive and reverse directions, and an extrusion lubrication effect and a micro-scale elastic fluid hydrodynamic lubrication effect can be generated between the convergent wedges and the opposite surfaces; the bearing capacity and service life of the bearing can be improved through the extrusion lubrication and micro-scale elastic fluid hydrodynamic lubrication; the micro-pit oil pockets at the adhesion joint between the bearing bush matrix and the soft material layer are uniformly and regularly distributed, and therefore the distributed sliding bearing is simple to machine; and moreover, the soft material and the bearing bush matrix can be adhered together, and the bearing is easy to manufacture.

Background technique
The condition that forms hydrldynamic pressure lubrication in the sliding bearing has three: between two lubricated surfaces wedge gap must be arranged; Must be full of lubricant medium between two lubricated surfaces with viscosity; Between two lubricated surfaces certain relative sliding velocity must be arranged, its moving direction must make lubricant medium flow to by big mouthful, flows out from osculum.Lubricant medium can be lubricant oil, water, air or lubricating grease etc.
In general sliding bearing, generally have only a convergence wedge shape between axle journal and the bearing shell, the hydrodynamic lubrication effect is limited, has limited the bearing capacity of bearing, the working life of also having reduced bearing simultaneously.By at bearing shell matrix surface bonding one deck soft material, and arranging in bearing shell matrix and soft material bonding part and when bearing shell rotates, can in the bearing play, form hundreds and thousands of individual wedge shapes that restrain by equally distributed little hole oil bag; The convergence wedge shape can be lubricated by positive and negative both direction; Can produce extruding lubricating effect and miniature scale elastic hydrodynamic lubrication effect between convergence wedge shape and apparent surface, thereby improve the bearing capacity and the working life of bearing.
Summary of the invention
The purpose of this utility model is to provide a kind of bearing shell matrix surface to have the distributed sliding bearing of little hole oil bag.
The technical solution adopted in the utility model is:
The utility model is at the bearing shell matrix surface of sliding bearing bonding one deck soft material, and symmetry is evenly equipped with a plurality of little holes respectively in bearing shell matrix and soft material bonding part, forms that a plurality of little holes are oily wraps.
When described sliding bearing is thrust slide bearing, at bearing shell body upper surface bonding one deck soft material.
When described sliding bearing is radial plain bearing, at bearing shell matrix internal surface bonding one deck soft material.
Described little hole oil bag is spheroidal or the elliposoidal of millimeter to the micron number magnitude.
The beneficial effect that the utlity model has is:
1, the utility model is by arranging equally distributed little hole oil bag at bearing shell matrix and soft material bonding part, can in bearing, form a plurality of convergence wedge shapes, the convergence wedge shape can be lubricated by positive and negative both direction, can produce extruding lubricating effect and miniature scale elastic hydrodynamic lubrication effect between convergence wedge shape and apparent surface.
2, bearing capacity and the working life that the extruding of miniature scale is lubricated and elastic hydrodynamic lubrication can improve bearing.

Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1 and Figure 2, the utility model is at the bearing shell matrix surface of sliding bearing bonding one deck soft material, and symmetry is evenly equipped with a plurality of little holes respectively in bearing shell matrix and soft material bonding part, forms that a plurality of little holes are oily wraps.
When described as shown in Figure 1 sliding bearing is thrust slide bearing, at bearing shell matrix 2 upper surfaces bonding one deck soft material, symmetrical respectively uniform a plurality of little holes oil bag 1 in bearing shell matrix 2 and soft material bonding part.
When described as shown in Figure 2 sliding bearing is radial plain bearing, at bearing shell matrix 5 internal surfaces bonding one deck soft material 4, symmetrical respectively uniform a plurality of little holes oil bag 6 in bearing shell matrix 5 and soft material 4 bonding parts, wherein 3 is bearing.
Described little hole oil bag is spheroidal or the elliposoidal of millimeter to the micron number magnitude.
Described soft material is MoS
2Doped graphite or MoS
2Doping PTFE composite solid lubricant material.
As shown in Figure 3, be the working principle explanatory drawing of described distributed sliding bearing.When 7 rotations of bearing shell matrix, bearing shell matrix 7 surfaces are under pressure, and soft material 8 deforms.Soft material 8 projectioies above little hole oil bag 9, the depression that the soft material 8 around little hole oil bag 9 is relative, thus in the bearing play, form a plurality of convergence wedge shapes 11; Convergence wedge shape 11 can be lubricated by positive and negative both direction; Lubricant medium 10 between convergence wedge shape and apparent surface can produce the extruding lubricating effect and the elastic hydrodynamic lubrication effect of miniature scale, thereby improves the bearing capacity and the working life of bearing.
Working principle of the present utility model is:
In general sliding bearing, generally have only a convergence wedge shape between axle journal and the bearing shell, the hydrodynamic lubrication effect is limited, has limited the bearing capacity of bearing, the working life of also having reduced bearing simultaneously.By at bearing shell matrix surface bonding one deck soft material, and arranging in bearing shell matrix and soft material bonding part that equally distributed little hole is oily and wrapping.When the bearing shell matrix rotated, the bearing shell matrix surface was under pressure, and soft material deforms.Soft material projection in the oil side of wrapping, little hole, the soft material depression around the oil bag of little hole, thus in the bearing play, form hundreds and thousands of convergence wedge shapes; The convergence wedge shape can be lubricated by positive and negative both direction; Can produce extruding lubricating effect and miniature scale elastic hydrodynamic lubrication effect between convergence wedge shape and apparent surface, thereby improve the bearing capacity and the working life of bearing.
As shown in Figure 3, be the miniature scale oil film wedge figure on bearing shell surface.
Above-mentioned embodiment is used for the utility model of explaining; rather than the utility model limited; in the protection domain of spirit of the present utility model and claim, any modification and change to the utility model is made all fall into protection domain of the present utility model.
