Abstract
The utility model discloses an efficient self -lubricating round pin axle, establish at the epaxial manganese of round pin cover and self -lubricating cover including round pin axle and cover, the self -lubricating cover is located between round pin axle and the manganese cover to fixed cover is established at the round pin epaxially. The utility model provides an axle is sold in the grab bucket can produce the lubrication automatically in the use of grab bucket, need not artifical the maintenance to alleviate with the wearing and tearing of manganese cover, effectively solve among the prior art round pin axle and refuel difficult problem.
Description
Technical field
The utility model relates to a kind of 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.
Bearing pin in existing grab bucket, in the using process of grab bucket, needs often to refuel, and reduces wearing and tearing.See Fig. 1, it is depicted as the scheme of installation of bearing pin in existing grab bucket.As seen from the figure, existing grab bucket bearing pin 1 is directly arranged with manganese cover 2, on bearing pin 1, is also provided with tank filler sleeve 3 simultaneously, add lubricant oil by this tank filler sleeve 3 to the contact fitting surface between manganese cover 2 and bearing pin 1.
Although can conveniently be refueled for bearing pin 1 by tank filler sleeve 3, some bearing pin in grab bucket, the height of location comparison, artificial climbing is needed when refueling, not only add the time of unloading, the labor intensity too increasing workman, with dangerous, more seriously have impact on the operating efficiency of boats and ships.
Model utility content
For the problem existing for the bearing pin in existing grab bucket is in lubrication, the purpose of this utility model is to provide a kind of bearing pin realizing selflubricating, refuels difficult problem to solve bearing pin in prior art.
In order to achieve the above object, the utility model adopts following technological scheme:
A kind of selflubricating bearing pin efficiently, comprise bearing pin and be set in the manganese cover on bearing pin, it also comprises selflubricating cover, and described selflubricating is overlapped between bearing pin and manganese overlap, and fixed cover is located on bearing pin.
Preferably, described selflubricating cover is copper sheathing, and it is provided with some selflubricating grooves on the surface, fills lubricating graphite powder in this selflubricating groove.
Preferably, described selflubricating groove is covered with the surface of copper sheathing.
Preferably, described selflubricating groove is even apart from distribution along copper sheathing circumferencial direction, is axially crisscross arranged successively along copper sheathing.
The grab bucket bearing pin that the utility model provides in the using process of grab bucket, can produce lubrication, without the need to manual maintenance, and alleviates the wearing and tearing of overlapping with manganese automatically, effectively solves bearing pin oiling difficult problem in prior art.
In addition, when this grab bucket bearing pin is changed, only need change selflubricating cover, i.e. copper sheathing, without the need to manual maintenance, reduce replacing construction, save cost.
Accompanying drawing explanation
The utility model is further illustrated below in conjunction with the drawings and specific embodiments.
Fig. 1 is the scheme of installation of existing bearing pin;
Fig. 2 is the structural representation of bearing pin in the 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. 2, it is depicted as the structural representation of novel self-lubricating bearing pin in this example.As seen from the figure, this selflubricating bearing pin 100 mainly comprises pin body 101, manganese cover 102 and selflubricating cover 103 3 parts.
Wherein, pin body 101 is overall substantially identical with the structure of existing bearing pin, and difference is, this pin body 101 does not have tank filler sleeve.
Selflubricating is overlapped 103 and is sheathedly fixed in pin body 101, and manganese cover 102 is set on selflubricating cover 103 simultaneously, overlaps 103 and produces lubrications, alleviate the wearing and tearing of overlapping with manganese by selflubricating.
For this reason, this selflubricating cover 103 is specially a copper sheathing, and the surface of copper sheathing is provided with some selflubricating grooves 104, fills lubricating graphite powder 105 in these selflubricating grooves.Copper sheathing with lubricating graphite powder is adopted drive fit and bearing pin admittedly, produces lubrication by lubricating graphite powder 105 when manganese cover relatively rotates with copper sheathing.
These selflubricating grooves 104 are even apart from distribution along copper sheathing circumferencial direction, axially interlock successively along copper sheathing, arrange the surface being covered with copper sheathing thus.
Shape for selflubricating groove 104 generally adopts circle, but is not limited to this; Size and number for selflubricating groove 104 can be determined according to the actual requirements.
The selflubricating bearing pin 100 formed thus can produce lubrication effect automatically when double-jaw grab bucket work, without the need to hand oiling, effectively solves bearing pin oiling difficult problem in prior art.
When double-jaw grab bucket work, stressed serious wear is overlapped with manganese in existing bearing pin surface, needs often to shut down to refuel to change bearing pin; And graphite can produce lubrication on this bearing pin copper sheathing, without the need to manual maintenance, and alleviate the wearing and tearing of overlapping with manganese; And only need change copper sheathing when changing, without the need to manual maintenance, reduce replacing construction, save cost.
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.
