Description
Technical field
The present invention relates to bushing technical field, and in particular to a kind of composite bush with damping wear-resisting functions.
Background technology
Bushing plays the ring set of pad.In valve applications field, bushing is within bonnet, typically using polytetrafluoroethylene (PTFE)
Or the anticorrosive material such as graphite, for sealing function.In moving component, the abrasion of part is caused because of long-term friction,
When axle and the gap wear in hole to a certain extent when have to renewal part, therefore designer when design from hard
It is axle sleeve or bushing to spend the preferable material of relatively low, wearability, the abrasion of axle and seat can be so reduced, when axle sleeve or liner wear
Changed to a certain extent, can so save the cost because changing axle or seat.
In the prior art, the abrasion between bushing madial wall and power transmission shaft is the most violent, and oil film its thickness set
It is relatively low, cause the service life of bushing shorter；Existing bushing does not have damping, buffering function, and using effect is not good.
The content of the invention
It is an object of the invention to provide a kind of composite bush with damping wear-resisting functions, to solve above-mentioned background technology
The problem of middle proposition.
To achieve the above object, the present invention provides following technical scheme：
On a kind of composite bush with damping wear-resisting functions, including neck bush and external bushing, the neck bush madial wall
Provided with helical oil groove；The external bushing is provided with three layers, and external bushing is followed successively by the first mounting layer, rubber layer and second from the inside to the outside
Mounting layer, the circumferential side wall of the neck bush and external bushing is provided with the alignment pin of upright circumferential wall, alignment pin insertion neck bush
In the coaxial positioning hole in external bushing circumferential wall.
It is used as further scheme of the invention：The neck bush manufactures for copper material.
It is used as further scheme of the invention：First mounting layer and the second mounting layer are steel plate layer.
The lubrication between neck bush and power transmission shaft is substantially increased the beneficial effects of the invention are as follows the oil groove of helical structure
Oily thickness, the largely smaller abrasion of neck bush, extends the service life of neck bush；Rubber layer causes damping to imitate
It is really good, there is protective effect to power transmission shaft, and with lightweight feature.
Brief description of the drawings
Fig. 1 is structural representation of the invention；
Fig. 2 is the structural representation of external bushing of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
Refer in Fig. 1 and Fig. 2, the embodiment of the present invention, a kind of composite bush with damping wear-resisting functions, including liner
Set 1 and external bushing 2, the madial wall of neck bush 1 is provided with helical oil groove 3, in the oil groove of helical structure is substantially increased
Lubricating oil thickness between bushing 1 and power transmission shaft, the largely smaller abrasion of neck bush 1, extends neck bush 1
Service life；
The external bushing 2 is provided with three layers, and external bushing 2 is followed successively by the first mounting layer 21, rubber layer 22 and second from the inside to the outside
Mounting layer 23, the mounting layer 23 of the first mounting layer 21 and second is steel plate layer, causes good damping effect provided with rubber layer 22,
There is protective effect to power transmission shaft, and with lightweight feature.
The circumferential side wall of the neck bush 1 and external bushing 2 is provided with the alignment pin 3 of upright circumferential wall, and alignment pin 3 is embedded in interior
In coaxial positioning hole on bushing 1 and the circumferential wall of external bushing 2.
The neck bush 1 manufactures for copper material.
The present invention the course of work be：The oil groove of helical structure substantially increases the profit between neck bush 1 and power transmission shaft
Lubricating oil thickness, the largely smaller abrasion of neck bush 1, extends the service life of neck bush 1；Provided with rubber layer 22
So that good damping effect, has protective effect to power transmission shaft, and with lightweight feature.
It is obvious to a person skilled in the art that the invention is not restricted to the details of above-mentioned one exemplary embodiment, Er Qie
In the case of without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter
From the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, the scope of the present invention is by appended power
Profit is required rather than described above is limited, it is intended that all in the implication and scope of the equivalency of claim by falling
Change is included in the present invention.Any reference in claim should not be considered as to the claim involved by limitation.
Moreover, it will be appreciated that although the present specification is described in terms of embodiments, not each embodiment is only wrapped
Containing an independent technical scheme, this narrating mode of specification is only that for clarity, those skilled in the art should
Using specification as an entirety, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art
It may be appreciated other embodiment.
