Description
Technical field
This utility model relates to self-lubricating bearing design and manufacturing technology field, refers specifically to a kind of automatic compensation type certainly
Lubrication bearing.
Background technology
Self-lubricating bearing is divided into composite material self-lubricating bearing, solid embedded self-lubricating bearing, bimetallic material self-lubricating
Bearing, special material self-lubricating bearing, according to different purposes and operating mode, select different self-lubricating bearings.One of them big class
Solid embedded self-lubricating bearing (being called for short JDB) is a kind of novel lubrication having metal bearing feature and Nonlubricated bearing feature concurrently
Bearing, is born load by metallic matrix, and the solid lubricant of special formulation plays lubrication.It is high that it has bearing capacity, resistance to
Impact, high temperature resistant, the features such as self-lubricating capacities is strong, it is particularly well-suited to heavy duty, low speed, reciprocal or swing etc. is difficult to lubricate and formed
The etch of the occasion of oil film, the most water funk punching and other acid solution and washing away.But existing self-lubricating bearing is when work one section
After between, its lubricant can not well play lubrication, main reason is that lubricant, than bearing body quick abrasion, works as table
After the lubricant attrition in face is fallen, enough lubrications in follow-up a very long time, cannot be provided, and, install at bearing
At the initial stage, owing to being oilless bearing, therefore with axle part, dry friction can occur, the mechanical performance of bearing and axle is brought the biggest not
Good impact.
Utility model content
The purpose of this utility model is for the deficiencies in the prior art, it is provided that a kind of automatic compensation self-lubricating bearing.
For solving the problems referred to above, this utility model offer techniques below scheme:
A kind of automatic compensation self-lubricating bearing, including being provided with the bearing body of some stuffing holes, described stuffing hole is blind
Hole, is provided with compensation between being filled with at the bottom of solid lubricant, and the hole of solid lubricant and described stuffing hole in stuffing hole
Spring；It is equipped with guiding surface at described bearing body both ends open；Described bearing body inner surface is provided with adjustment layer.
Further, described guiding surface and described bearing body is axial in 20 ° of angles.
Further, the end face at described bearing body two ends is designed with assemble gap.
Further, described stuffing hole is along the uniform setting of circumferencial direction of described bearing body.
Further, described solid lubricant is bar-shaped graphite or molybdenum bisuphide, solid lubricant and described filler
0.1-0.5mm gap is left between hole.
Further, described bearing body uses brass alloys or bell metal.
Further, described adjustment layer is graphite linings or layer of molybdenum-disulfide.
Further, the thickness of described adjustment layer is 0.05-0.1mm.
Beneficial effect:
1) it is inlaid with solid lubricant in bearing body, there is self-lubricating property.It addition, solid lubricant is by compensating
Spring props up, and owing to counterbalance spring has certain decrement, during bearing working, solid lubricant can be along with mill
Damage, counterbalance spring outwards extrude, automatically compensate wear extent, remain good lubricant effect.
2) it is equipped with guiding surface at bearing body both ends open, when the workpiece such as axle installed by the bearing assembled, is leading
Under the guiding function on inclined-plane, being highly susceptible to assembling, the workpiece such as axle is easily inserted in the dead eye of bearing, and assembly difficulty is low, saves
Shi Shengli.
3) it is designed with on the end face at bearing body two ends assembling gap, it is possible to use the instruments such as clamp block assembling gap,
Rolling bearing body back and forth, is beneficial to assembling.

Detailed description of the invention
Below in conjunction with Figure of description and embodiment, specific embodiment of the utility model is described in further detail:
A kind of automatic compensation self-lubricating bearing, as depicted in figs. 1 and 2, including the bearing body being provided with some stuffing holes
1, described stuffing hole is blind hole, is filled with solid lubricant 2 in stuffing hole, and solid lubricant 2 and described stuffing hole
Hole at the bottom of between be provided with counterbalance spring 3；It is equipped with guiding surface 4 at described bearing body 1 both ends open；Described bearing body 1
Inner surface is provided with adjustment layer 5.Above-mentioned bearing body 1 preferably employs brass alloys or bell metal.
Wherein, described guiding surface 4 and described bearing body 1 is axial in 20 ° of angles.The bearing assembled is installed
During the workpiece such as axle, under the guiding function of guiding surface 4, being highly susceptible to assembling, the workpiece such as axle is easily inserted the dead eye of bearing
In.
Wherein, the end face at described bearing body 1 two ends is designed with assemble gap 6.The instruments such as clamp can be utilized to block
Assembling gap 6, carrys out rolling bearing body, is beneficial to assembling.
Wherein, described stuffing hole is along the uniform setting of circumferencial direction of described bearing body 1.Ensure that solid lubricant 2 exists
The full-scale interior of bearing all could be formed with effect lubrication, it is ensured that splendid lubricant effect.
Wherein, described solid lubricant 2 is bar-shaped graphite or molybdenum bisuphide, and high lubricating effect, service life is long.Gu
Leave 0.1-0.5mm gap between body lubriation material 2 and described stuffing hole, facilitate counterbalance spring to be ejected by solid lubricant.
Above-mentioned adjustment layer 5 is graphite linings or layer of molybdenum-disulfide.Adjustment layer 5 thickness is unsuitable excessive, also unsuitable too small, therefore,
The thickness of adjustment layer 5 preferably chooses 0.05mm-0.1mm, solid profit in ensureing good lubrication effect and sealing stuffing hole
The effect of sliding material 2 simultaneously, also ensures the elaboration that bearing coordinates with axle part.
It is inlaid with solid lubricant in bearing body in this utility model, there is self-lubricating property.It addition, solid profit
Sliding material is propped up by counterbalance spring, owing to counterbalance spring has certain decrement, during bearing working, and solid lubrication material
Material can outwards be extruded by counterbalance spring, automatically compensate wear extent along with abrasion, remain good lubricant effect.
The above, be only preferred embodiment of the present utility model, not make technical scope of the present utility model
Go out any restriction, thus every according to technical spirit of the present utility model, above example is made any trickle amendment, equivalent
Change and modification, all still fall within the range of the technical solution of the utility model.
