Abstract
The utility model discloses a self -lubricating round pin axle, it is including a round pin axle body, and should round pin body begin on the surface has a plurality ofly from lubrication grooves, pack the lubricating graphite powder in lubrication grooves. The utility model provides an in the scheme, through being covered with graphite from lubrication grooves on the surface at the round pin axle, produce lubrication action from this, realize the self -lubricating, reduce the wearing and tearing of axle to reduce manual work time of refueling and danger, the problem effectively solving prior art and exist.
Description
Technical field
The utility model relates to grab bucket, is specifically related to the bearing pin on grabbing bucket.
Background technique
Double-jaw grab bucket is a kind of bulk goods cargo unloader that port and pier comparatively generally use, and along with being on the increase of port discharge kind, increasing bulk material needs to unload a ship with double-jaw grab bucket.
Rotation movable part in double-jaw grab bucket is all generally realize connecting by grab bucket bearing pin.In the using process of double-jaw grab bucket, grab bucket bearing pin needs often to refuel, and reduces wearing and tearing.
The oiling work of grab bucket bearing pin is all generally by manually having come.Because the bearing pin in double-jaw grab bucket is more, some bearing pin is positioned at lower position, easily realizes hand oiling; Effective bearing pin is positioned at higher position, then when carrying out axle oiling, manually climbs eminence refuel with regard to needs.This not only adds the time of unloading, and the labor intensity too increasing workman, with dangerous, more seriously have impact on the operating efficiency of boats and ships.
As can be seen here, a kind of selflubricating bearing pin without the need to hand oiling is provided to be the technical problem that related domain needs solution badly.
Model utility content
For the problem of bearing pin existing for lubrication strategies in existing double-jaw grab bucket, the purpose of this utility model is to provide a kind of selflubricating bearing pin without the need to hand oiling.
In order to achieve the above object, the scheme of the utility model employing is as follows:
A kind of selflubricating bearing pin, it comprises pin body, and the surface of described pin body starts some selflubricating grooves, fills lubricating graphite powder in described selflubricating groove.
Preferably, described selflubricating groove is covered with the surface of pin body.
Preferably, on the bearing of trend of described pin body, even distance is distributed with the selflubricating groove of some layers, and the selflubricating groove in every layer is even apart from distribution along the circumferencial direction of pin body, and the selflubricating groove between adjacent layer is crisscross arranged successively.
Preferably, described selflubricating groove is circular, is circular arc bottom it.
In the scheme that the utility model provides, be covered with graphite by selflubricating groove on the surface at bearing pin, produce lubrication thus, realize selflubricating, reduce the wearing and tearing of axle, thus reduce hand oiling time and danger, effectively solve the problem existing for prior art.
In addition, the scheme that the utility model provides simply is easy to realize, and has good prospect of the application.
Accompanying drawing explanation
The utility model is further illustrated below in conjunction with the drawings and specific embodiments.
Fig. 1 is structural representation of the present utility model.
Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
See Fig. 1, be depicted as the structural representation of the selflubricating bearing pin provided in this example.As seen from the figure, this selflubricating bearing pin 100 mainly comprises pin body 101, and the agent structure of this pin body 101 is same as the prior art, is not repeated herein.
In order to realize selflubricating, this example offers some selflubricating grooves 102 on the surface of pin body 101, fills lubricating graphite powder 103 in these selflubricating grooves 102.
In order to reach good lubrication effect, these selflubricating grooves 102 are covered with the whole surface of pin body 101.Concrete, on the surface of pin body 101, along on the bearing of trend of pin body 101, some selflubricating grooves 102 are divided into some layers, and even apart from distribution along the bearing of trend of pin body 101.
And in every layer, some selflubricating grooves 102 are even according to distribution along the circumferencial direction of pin body 101, and be crisscross arranged successively (as shown in the figure) between selflubricating groove in adjacent layer.
Distribution mode for selflubricating groove 102 is not limited to such scheme, also can adopt other distribution mode as required, as array-type etc.
In addition, adopt cross section to be circular groove for selflubricating groove 102, but be not limited to this, as required, this this selflubricating groove 102 can adopt ellipse or long-round-shape groove.During according to long-round-shape groove, its extension program can be arranged along pin body 101 circumferencial direction.
On this basis, the bottom for selflubricating groove 102 adopts arc surface to arrange, and is convenient to the filling of lubricating graphite powder 103 here.But be not limited to this, the bottom of selflubricating groove 102 can adopt the setting of other scheme equally as required.
The degree of depth for selflubricating groove 102 is determined according to the actual requirements, generally between 0.5cm-5cm.
Openings of sizes for selflubricating groove 102 is determined according to the actual requirements, the openings of sizes of selflubricating grooves 102 all in this example is consistent, be not limited to this, the selflubricating groove 102 of different openings size can be adopted as required, as the bearing of trend in pin body 101, the selflubricating groove of different openings size between adjacent layer, can be adopted.
According to such scheme form selflubricating bearing pin 100 in use, full lubricating graphite powder 103 is filled in selflubricating groove 102 on bearing pin surface, like this when when double-jaw grab bucket work, lubricating graphite powder 103 in selflubricating groove 102 is covered with whole bearing pin surface with contact component, in bearing pin rotation process, graphite on its surface can produce lubrication, realizes selflubricating, reduces abrasion.
More than show and describe basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
