Abstract
The invention discloses the distributed sliding bearing of a kind of bearing shell matrix surface with micro-hole oil bag.To bond one deck soft material at the bearing shell matrix surface of sliding bearing, in bearing shell matrix and soft material bonding part, symmetry is evenly equipped with multiple micro-hole respectively, forms multiple micro-holes oil bag.The present invention is by arranging that at bearing shell matrix and soft material bonding part equally distributed micro-oil of cheating wraps, multiple convergence wedge shapes can be formed within the bearing, convergence wedge shape can positive and negative both direction be lubricated, and can produce and extrude lubricating effect and miniature scale elastic hydrodynamic lubrication effect between convergence wedge shape and apparent surface; The extruding lubrication of miniature scale and elastic hydrodynamic lubrication can improve bearing capacity and the working life of bearing; Bearing shell matrix and soft material bonding part micro-cheats oil and wrap and be evenly distributed regular, and processing simply; Soft material and bearing shell matrix can be bonded together, and are easy to manufacture.
Description
Technical field
The present invention relates to a kind of sliding bearing, especially relate to the distributed sliding bearing of a kind of bearing shell matrix surface with micro-hole oil bag.
Background technique
The condition forming hydrldynamic pressure lubrication in sliding bearing has three: must have wedge gap between two lubricated surfaces; The lubricant medium with viscosity must be full of between two lubricated surfaces; Must have certain relative sliding velocity between two lubricated surfaces, its moving direction must make lubricant medium be flow to by large mouth, flows out from osculum.Lubricant medium can be lubricant oil, water, air or lubricating grease etc.
In general sliding bearing, generally only have one to restrain wedge shape between axle journal and bearing shell, hydrodynamic lubrication limited efficiency, limits the bearing capacity of bearing, also reduces the working life of bearing simultaneously.By one deck soft material that bonds at bearing shell matrix surface, and arrange that equally distributed micro-oil of cheating wrap at bearing shell matrix and soft material bonding part, when bearing shell rotates, can be formed in bearing play and hundreds and thousands ofly individually restrain wedge shapes; Convergence wedge shape can positive and negative both direction be lubricated; Can produce between convergence wedge shape and apparent surface and extrude lubricating effect and miniature scale elastic hydrodynamic lubrication effect, thus improve bearing capacity and the working life of bearing.
Summary of the invention
The object of the present invention is to provide a kind of bearing shell matrix surface with the distributed sliding bearing of micro-hole oil bag.
The technical solution used in the present invention is:
The present invention to bond one deck soft material at the bearing shell matrix surface of sliding bearing, and in bearing shell matrix and soft material bonding part, symmetry is evenly equipped with multiple micro-hole respectively, forms multiple micro-holes oil bag.
When described sliding bearing is thrust slide bearing, to bond one deck soft material at bearing shell body upper surface.
When described sliding bearing is radial plain bearing, to bond one deck soft material at bearing shell base inner surface.
Described micro-hole oil bag is for millimeter is to the spheroidal of micron number magnitude or elliposoidal.
The beneficial effect that the present invention has is:
1, the present invention is by arranging that at bearing shell matrix and soft material bonding part equally distributed micro-oil of cheating wraps, multiple convergence wedge shapes can be formed within the bearing, convergence wedge shape can positive and negative both direction be lubricated, and can produce and extrude lubricating effect and miniature scale elastic hydrodynamic lubrication effect between convergence wedge shape and apparent surface.
2, the extruding lubrication of miniature scale and elastic hydrodynamic lubrication can improve bearing capacity and the working life of bearing.
3, bearing shell matrix and soft material bonding part micro-cheats oil and wrap and be evenly distributed regular, and processing simply; Soft material and bearing shell matrix can be bonded together, and are easy to manufacture.

In figure: 1, micro-hole oil bag, 2, bearing shell matrix, 3, bearing, 4, soft material, 5, bearing shell matrix, 6, micro-hole oil bag, 7, bearing shell matrix, 8, soft material, 9, micro-hole oil wraps, 10, lubricant medium, 11, restrain wedge shape.
Embodiment
Below in conjunction with drawings and Examples, the present invention is further illustrated.
As shown in Figure 1 and Figure 2, the present invention to bond one deck soft material at the bearing shell matrix surface of sliding bearing, and in bearing shell matrix and soft material bonding part, symmetry is evenly equipped with multiple micro-hole respectively, forms multiple micro-holes oil bag.
When described sliding bearing is thrust slide bearing as shown in Figure 1, to bond one deck soft material at bearing shell matrix 2 upper surface, in bearing shell matrix 2 and soft material bonding part, symmetrical uniform multiple micro-hole oilyly wraps 1 respectively.
When described sliding bearing is radial plain bearing as shown in Figure 2, to bond one deck soft material 4 at bearing shell matrix 5 internal surface, in bearing shell matrix 5 and soft material 4 bonding part, symmetrical uniform multiple micro-hole oilyly wraps 6 respectively, and wherein 3 is bearing.
Described micro-hole oil bag is for millimeter is to the spheroidal of micron number magnitude or elliposoidal.
Described soft material is MoS
2doped graphite or MoS
2adulterated PTFE composite solid lubricant material.
As shown in Figure 3, be the working principle explanatory drawing of described distributed sliding bearing.When bearing shell matrix 7 rotates, bearing shell matrix 7 surface is under pressure, and soft material 8 deforms.Soft material 8 above micro-hole oil bag 9 is protruding, the depression that the soft material 8 around micro-hole oil bag 9 is relative, thus in bearing play, form multiple convergence wedge shape 11; Convergence wedge shape 11 can positive and negative both direction be lubricated; Lubricant medium 10 between convergence wedge shape and apparent surface can produce extruding lubricating effect and the elastic hydrodynamic lubrication effect of miniature scale, thus improves bearing capacity and the working life of bearing.
Working principle of the present invention is:
In general sliding bearing, generally only have one to restrain wedge shape between axle journal and bearing shell, hydrodynamic lubrication limited efficiency, limits the bearing capacity of bearing, also reduces the working life of bearing simultaneously.By one deck soft material that bonds at bearing shell matrix surface, and arrange that equally distributed micro-oil of cheating wraps at bearing shell matrix and soft material bonding part.When bearing shell matrix rotates, bearing shell matrix surface is under pressure, and soft material deforms.Protruding at the soft material of the oil side of wrapping, micro-hole, micro-hole oil bag soft material depression around, thus in bearing play, form hundreds and thousands of convergence wedge shapes; Convergence wedge shape can positive and negative both direction be lubricated; Can produce between convergence wedge shape and apparent surface and extrude lubricating effect and miniature scale elastic hydrodynamic lubrication effect, thus improve 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 explaining and the present invention is described, instead of limits the invention, and in the protection domain of spirit of the present invention and claim, any amendment make the present invention and change, all fall into protection scope of the present invention.
