Abstract
The utility model discloses a kind of self-lubricating structures of sliding bearing, solve the problems, such as that existing sliding bearing self-lubricating effect is poor, including axle sleeve, multiple holes are offered on the side wall of axle sleeve, kollag is embedded in each hole, it is characterized in that：Oil groove one and oil groove two are offered on the inner wall of the axle sleeve, the oil groove one is set into clockwise helical form, and the oil groove two is set in helical form counterclockwise；Oil groove three is offered on the outer wall of the axle sleeve, the oil groove three is set to be annular；Through hole is offered in the oil groove three, passes through oil groove one, oil groove two and oil groove three so that the self-lubricating function of sliding bearing at work is obviously improved, to reduce the frictional force of sliding surface.
Description
Technical field
The utility model is related to a kind of sliding bearings, more particularly relate to a kind of self-lubricating structure of sliding bearing.
Background technology
Happens is that sliding friction when sliding bearing works, force of sliding friction depends mainly on the size of the accuracy of manufacture, and
The material for depending mainly on the size of bearing sliding surface of sliding bearing frictional force and the self-lubricating work(of sliding bearing working face
Can, and the self-lubricating effect of sliding bearing working face is relatively poor in the prior art, there is the spaces of raising.
Utility model content
In view of the deficiencies of the prior art, the utility model provides a kind of self-lubricating structure of sliding bearing so that slides
The self-lubricating function of bearing at work is obviously improved, to reduce the frictional force of sliding surface.
To achieve the above object, the utility model provides following technical solution：
A kind of self-lubricating structure of sliding bearing including axle sleeve, offers multiple holes, each hole on the side wall of axle sleeve
Inside embedded with kollag, oil groove one and oil groove two are offered on the inner wall of the axle sleeve, the oil groove one is into clockwise
Helical form is set, and the oil groove two is set in helical form counterclockwise；Oil groove three, the oil are offered on the outer wall of the axle sleeve
Slot three is set to be annular；Through hole is offered in the oil groove three.
Preferably, the section of the oil groove one, oil groove two and oil groove three is semicircle.
Preferably, the through hole is connected with oil groove one or oil groove two.
Preferably, there is chamfering on the end wall of the axle sleeve.
Preferably, the kollag is graphite.
The advantages of the utility model：Graphite has oil suction effect under room temperature, has the function of to drain the oil after temperature rise, and oil groove
First, oil groove two and oil groove three can store to be lubricated to component the lubricating oil of releasing, while be also prevented from lubrication oil stream
The situation of mistake；Oil groove one and oil groove two are that helical form is set, can be distributed on the inner wall of axle sleeve more it is uniform extensively, play
The effect of even lubrication；Oil groove one is clockwise, and oil groove two is counterclockwise, which may be such that oil groove one and oil groove two with multiple
Joint so as to further promote lubricating oil being uniformly distributed on axle sleeve, plays uniform lubricant effect, reduces component and this
The frictional force of axle sleeve；The setting of oil groove three and through hole realizes the effect that lubricating oil circulates inside and outside axle sleeve, so as to further
Uniform lubricant effect is played, reduces frictional force whole during axle sleeve work.
Description of the drawings
The schematic diagram of the self-lubricating structure for the sliding bearing that Fig. 1 is provided by the present embodiment；
The sectional view of the self-lubricating structure for the sliding bearing that Fig. 2 is provided by the present embodiment.
Specific embodiment
The self-lubricating structure of the utility model sliding bearing is further described by Fig. 1 to Fig. 2.
A kind of self-lubricating structure of sliding bearing including axle sleeve 1, offers multiple holes, Mei Gekong on the side wall of axle sleeve 1
Kollag is embedded in cave（Hole and kollag do not mark in Figure of description）, the inner wall of the axle sleeve 1
On offer oil groove 1 and oil groove 26, the clockwise helical form of one 5 one-tenth of oil groove is set, and the oil groove 26 is in counterclockwise
Helical form set, therefore between oil groove 1 and oil groove 26 have multiple intersections so that lubricating oil can be in oil groove 1 and oil
It is flowed between slot 26, plays uniform lubricant effect, the both ends of oil groove 1 and oil groove 26 are closed, and prevent lubricating oil from oil groove
1 or oil groove 26 in situation about revealing；Oil groove 32 is offered on the outer wall of the axle sleeve 1, the oil groove 32 sets for ring-type
It puts, offers through hole 3 in the oil groove 32, oil groove 32 can store the lubricating oil on 1 outer wall of axle sleeve during work, simultaneously
Circulation inside and outside lubricating oil can be realized by through hole 3, to reach effective lubricant effect so that at work, 1 sliding surface of axle sleeve
Frictional force significantly reduced.
Further, the section of the oil groove 1, oil groove 26 and oil groove 32 is semicircle, and semicircular slot is to axis
The structural strength influence of set 1 is relatively low, ensure that the structural strength of axle sleeve 1.
Further, the through hole 3 is connected with oil groove 1 or oil groove 26, which can be achieved oil groove 1, oil groove 26
With the circulation of the lubricating oil in oil groove 32, it ensure that lubricating oil is uniformly distributed on axle sleeve 1, play effective lubricant effect,
Reduce frictional force when axle sleeve 1 works.
Further, there is chamfering 4, chamfering is divided into inner chamfer and outer chamfer, and inner chamfer can be square on the end wall of the axle sleeve 1
Just external component is caught in axle sleeve 1, and outer chamfer can facilitate axle sleeve 1 to snap fit onto in external component.
Further, the kollag is graphite.
The above is only the preferred embodiment of the utility model, and the scope of protection of the utility model is not limited merely to
Above-described embodiment, all technical solutions belonged under the utility model thinking belong to the scope of protection of the utility model.It should refer to
Go out, for those skilled in the art, several improvement under the premise of the utility model principle is not departed from and
Retouching, these improvements and modifications also should be regarded as the scope of protection of the utility model.
