Abstract
The utility model discloses a self-lubricating bearing which comprises an inner ring (1), an outer ring (2), a spring (3) and lubricating graphite (4), wherein a through hole (6) is formed in the inner ring (1), and a boss is formed in the upper end of the through hole; a hole (7) which corresponds to the inner ring (1) is formed in the outer ring (2); blind holes (5) which are uniformly distributed are formed in an inner wall of the outer ring (2); and the spring (3) and the lubricating graphite (4) are sequentially arranged in the blind holes (5). During use, the lubricating graphite (4) enters a gap between the inner ring (1) and the outer ring (2) to achieve a lubricating effect along with rotation of the inner ring (1), and the lubricating graphite (4) is easily replaced. The self-lubricating bearing is simple in structure and convenient to use and maintain and has long service life.
Description
Technical field
The utility model relates to field of bearings, relates in particular to a kind of self oiling bearing.
Background technique
In mechanical field, bearing has generally been used for fixing and reducing the effect of load friction factor.Press the difference of motor element frictional property, bearing can be divided into rolling bearing and sliding bearing two classes.
Using at present bearing comparatively is widely rolling bearing, but because its radial dimension is larger, therefore uses and be subject to certain restrictions; Thereby be restricted or during high-speed overload, conventionally use sliding bearing when radial dimension.Because bearing itself is also a kind of mechanical component, bearing self also needs to lubricate; Lubricate and realize by oiling agent, conventional oiling agent is lubricant oil, but its chemical property is unstable, perishable under high temperature, therefore needs frequent replacing, wastes time and energy.
Model utility content
(1) technical problem that will solve
The technical problems to be solved in the utility model is to provide a kind of self-lubricating plain bearing.
(2) technological scheme
For solving the problems of the technologies described above, the utility model provides a kind of self oiling bearing, comprises inner ring (1), outer ring (2), spring (3) and lubricating graphite (4); In described inner ring (1), be provided with through hole (6), its upper end is provided with boss; In described outer ring (2), be provided with and the corresponding hole (7) of described inner ring (1), described outer ring (2) inwall is also provided with equally distributed blind hole (5), and described spring (3) is arranged in described blind hole (5) successively with described lubricating graphite (4).
Wherein, described blind hole (5) has 3 at least.
Wherein, after described spring (3) installation, there is certain decrement.
Wherein, described inner ring (1) adopts Spielpassung with described outer ring (2).
Wherein, described outer ring (2) adopt powdered metallurgical material to make.
(3) beneficial effect
Compared with prior art, the utility model adopts the effect that lubricating graphite is realized selflubricating is installed on outer ring, and its cost is low, simple in structure.
Accompanying drawing explanation
Fig. 1 is the structural representation of self oiling bearing of the present utility model.
Fig. 2 is the exploded view of self oiling bearing of the present utility model.

Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but can not be used for limiting scope of the present utility model.
The structure of the utility model self oiling bearing as shown in Figure 1, comprises inner ring 1, outer ring 2, spring 3 and lubricating graphite 4; In described inner ring 1, be provided with through hole 6, its upper end is provided with boss; In described outer ring 2, be provided with and the corresponding hole 7 of described inner ring 1, described outer ring 2 inwalls are also provided with equally distributed blind hole 5, and described spring 3 is arranged in described blind hole 5 successively with described lubricating graphite 4.
In the present embodiment, described blind hole 5 has 3 at least.
In the present embodiment, after described spring 3 installations, there is certain decrement.
In the present embodiment, described inner ring 1 adopts Spielpassung with described outer ring 2.
In the present embodiment, described outer ring 2 adopts powdered metallurgical material to make.
Figure 2 shows that the exploded view of self oiling bearing of the present utility model.
Figure 3 shows that the structural representation of the lubricating graphite of self oiling bearing of the present utility model.
During use, spring 3 and lubricating graphite 4 are put into successively to the blind hole 5 of outer ring 2 inwalls, then inner ring 1 is inserted in outer ring 2 in corresponding with it hole 7, by the boss of inner ring upper end, fix; Inner ring 1 is Spielpassung with outer ring 2, in the middle of them, has small space, and lubricating graphite 4 is close to inner ring 1 under the elastic force effect of spring 3, and along with the rotation of inwall 1, a part of graphite enters in above-mentioned space, plays lubricated effect.Bearing used after a period of time, and along with the consumption of lubricating graphite 4, its length constantly reduces, and under the effect of spring 3, can constantly keep lubricating graphite 4 to be close to the outer wall of inner ring 1.When lubricating graphite 4 approach exhaustion, inwall 1 can be taken out, the lubricating graphite 4 more renewing, cost is low, simple to operate.
Considering will in outer ring, 2 inwall drilling blind hole 5 difficulty be larger, and the outer ring 2 of this self oiling bearing adopts powdered metallurgical material disposal pressed mouldings, and not only batch production is simply convenient in processing, and saves material and reduced cost.In addition adopt powdered metallurgical material once-through to have higher intensity to improve the working life of bearing.
The utility model adopts the effect that lubricating graphite is realized selflubricating is installed on outer ring, and its cost is low, simple in structure.
These are only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
