Abstract
The utility model discloses a kind of concentric rib bushings, including bushing and rib, the bushing is hollow circuit cylinder tubulose structure, the rib is annular structure, the right end of the bushing is arranged in the rib, the bushing inner wall is equipped with the oil-way of waveform or fold-line-shaped, the oil-way left end extends at the bushing left side position 5mm-10mm, the right end of the oil-way extends to the right side of the rib, and the intersection of the oil-way and the rib is equipped with lubricating oil added holes.The utility model can prevent outflow of lubrication oil bushing outer, lubricating oil storage capacity are big, add lubricating oil to facilitate.
Description
Technical field
The utility model relates to bushing field, especially a kind of concentric rib bushing.
Background technique
In moving component, the abrasion of part is caused because of long-term friction, when axis and the gap wear in hole are to certain
Renewal part is had to when degree, therefore designer's selection hardness when design is lower, the preferable material of wearability
For axle sleeve or bushing, the abrasion of axis and seat can be reduced in this way, when axle sleeve or liner wear are replaced to a certain extent, in this way
Can save because replacement axis or seat cost, in use, due to that still can be worn between bushing and axis, bushing and
Lubrication between axis just becomes particularly significant, and the design of the lubrication system of bush inside will have a direct impact on and moisten between bushing and axis
Sliding effect, to influence the service life of axis and bushing, existing bush inside lubricating oil runner design comes with some shortcomings, stream
Lubricating oil in road easily flows out bushing outer in use, in addition, the lubricating oil runner of existing bushing is storable
Lubricants capacity is less, it is therefore desirable to add than more frequently make-up oil moreover, the lubricating oil added holes of existing bushing is smaller
It is also inconvenient when adding lubricating oil, many adverse effects are brought to practical application.
Utility model content
In order to overcome drawbacks described above, the utility model, which provides one kind, can prevent outflow of lubrication oil bushing outer, lubricating oil
Storage capacity is big, adds lubricating oil easily concentric rib bushing.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of concentric rib bushing, including bushing
And rib, the bushing are hollow circuit cylinder tubulose structure, the rib is annular structure, and the rib is arranged in the bushing
Right end, the bushing inner wall is equipped with the oil-way of waveform or fold-line-shaped, and the oil-way left end is extended to apart from institute
It states at the position 5mm-10mm of bushing left side, the right end of the oil-way extends to the right side of the rib, the lubrication
The intersection of oil groove and the rib is equipped with lubricating oil added holes.
A kind of above-mentioned concentric rib bushing, it is 3mm-20mm that the bushing is identical with the thickness of the rib, described
Bushing and the rib are an integral structure or pass through welded connecting.
The material of a kind of above-mentioned concentric rib bushing, the bushing and the rib is copper or steel.
A kind of above-mentioned concentric rib bushing, the cross sectional shape of the oil-way is square or triangle, lubricating oil
The depth of slot is 1mm-5mm.
A kind of above-mentioned concentric rib bushing, the shape of the lubricating oil added holes are funnel-form.
The quantity of a kind of above-mentioned concentric rib bushing, the oil-way and the lubricating oil added holes is equal, is
3-12.
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 structure is simple, and it is easy to use, in bush inside, wave is set
The oil-way of shape or fold-line-shaped will drive lubricating oil in oil-way to waveform or folding when the axis rotation in bushing
It is flowed at the wave crest of linear runner or the position of trough, and then lubricating oil is locked in inside oil-way, prevent lubrication oil stream
It is arrived on the outside of bushing out, reduces the loss of lubricating oil, meanwhile, the design of the oil-way of waveform or fold-line-shaped can be lengthened effectively
The length of oil-way makes disposably store more lubricating oil in oil-way, to reduce the frequency of lubricating oil supplement
The design of rate, funnelform lubricating oil added holes can allow the easier lubricating oil for being added to bush inside of lubricating oil
In slot, facilitate the supplement of lubricating oil.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.

Specific embodiment
A kind of concentric rib bushing, including bushing 1 and rib 2, the bushing 1 are hollow circuit cylinder tubulose structure, the gear
Side 2 is annular structure, and the right end of the bushing 1 is arranged in the rib 2, and 1 inner wall of bushing is equipped with wavy lubrication
Oil groove 3,3 left end of oil-way extend at the 1 left side position 5mm of bushing, the right end of the oil-way 3
The right side of the rib 2 is extended to, the intersection of the oil-way 3 and the rib 2 is equipped with lubricating oil added holes 4.
Further, the bushing 1 is identical with the thickness of the rib 2, is 3mm, the bushing 1 and the rib 2
It is an integral structure.
Further, the material of the bushing 1 and the rib 2 is steel.
Further, the cross sectional shape of the oil-way 3 is square, and the depth of oil-way 3 is 1mm.
Further, the shape of the lubricating oil added holes 4 is funnel-form.
Further, the oil-way 3 is equal with the quantity of the lubricating oil added holes 4, is 12.
Above embodiments are only the exemplary embodiment of the utility model, are not used in limitation the utility model, this is practical new
The protection scope of type is defined by the claims.Those skilled in the art can be in the essence and protection scope of the utility model
It is interior, various modifications or equivalent replacements are made to the utility model, this modification or equivalent replacement also should be regarded as falling in originally practical new
In the protection scope of type.
