Description
Technical field
The utility model relates to bushing field, especially a kind of engineering machinery bushing.
Background technique
In mechanical transmission component, the abrasion of part can be often caused because of long-term friction, when the gap in axis and hole is ground
Damage to a certain extent when have to renewal part, therefore designer selects when design that hardness is lower, wearability compared with
Good material is axle sleeve or bushing, the abrasion of axis and seat can be reduced in this way, when axle sleeve or liner wear carry out to a certain extent
Replacement can save the cost because of replacement axis or seat in this way.In use, due to that still can be ground between bushing and axis
Damage, the lubrication between bushing and axis just becomes particularly significant, the design of the lubrication system of bush inside, will have a direct impact on bushing and
Lubricant effect between axis, to influence the service life of axis and bushing, there are one for existing bush inside lubricating oil runner design
A little defects, lubricating oil in runner is with using the increase of time usually to will appear the case where being unevenly distributed, such as grease
In in sleeve, lubricating oil concentrate on bushing one end etc., keep the internal lubrication of bushing insufficient, be easy to cause bushing and axis
Abrasion, lubricating oil also easily flows out bushing outer in use, causes the waste of lubricating oil, in addition, existing bushing
The storable lubricants capacity of lubricating oil runner is less, it is therefore desirable to than more frequently make-up oil, bring to practical application all
It is mostly inconvenient.
Utility model content
In order to overcome drawbacks described above, the utility model provides a kind of engineering machinery bushing, by using oppositely oriented two
Group helical form oil wire casing improves the uniformity of bush inside lubrication oil distribution, and oil storage tank is arranged in oily wire casing end, improves bushing
Interior lubrication oilreserves, oily wire casing and oil storage tank are respectively positioned on bushing inner wall, and do not extend into gasket end, and lubricating oil is locked in
In bushing, outflow of lubrication oil is avoided to cause to waste.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of engineering machinery bushing, including bushing
Cylinder, the lining sleeve lining are equipped with the first oily wire casing and the second oily wire casing, and the described first oily wire casing and the second oily wire casing are equal
For helical groove, the screw pitch and circle number of the described first oily wire casing and the second oily wire casing are equal, the described first oily wire casing with
Described second oily wire casing is oppositely oriented, and the both ends of the described first oily wire casing and the second oily wire casing are overlapped, and described first
Oily wire casing and the second oily wire casing are overlapped at the position of both ends and are equipped with oil storage tank, are additionally provided with note on the side wall of the bushing cylinder
Oilhole.
Above and below a kind of above-mentioned engineering machinery bushing, the upper and lower ends of the described first oily wire casing and the second oily wire casing
Both ends do not extend into the upper and lower end face of the bushing cylinder.
The spiral number of turns of a kind of above-mentioned engineering machinery bushing, the described first oily wire casing and the second oily wire casing are 1.
A kind of above-mentioned engineering machinery bushing, the oil filler point is located in the middle part of the described first oily wire casing and the second oily line
In the middle part of slot at crossover location.
The utility model has the following advantages that and high-lighting effect compared with prior art:
The utility model has the beneficial effects that the utility model is by using two groups of oppositely oriented helical form oil wire casings,
When bushing inner shaft rotates, axis will drive lubricating oil and flow along the first oily wire casing and the second oily wire casing, and profit inside two oily wire casings
The flow direction of lubricating oil is avoided lubricating oil from concentrating on sleeve or one end, mentioned on the contrary, be uniformly distributed to lubricating oil in bushing
High lubricant effect is arranged oil storage tank in oily wire casing end, improves the lubrication oilreserves in bushing, extends the addition week of lubricating oil
Phase, oily wire casing and oil storage tank are respectively positioned on bushing inner wall, and do not extend into gasket end, and lubricating oil is locked in bushing, is avoided
Outflow of lubrication oil causes to waste.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
