Description

A kind of oil-free bushing

Technical field

The utility model is related to valve applications field, more particularly to a kind of oil-free bushing.

Background technology

Bushing has been the ring set of liner effect, and in valve applications field, bushing, within valve gap, generally uses polytetrafluoroethyl-ne The resistant material such as alkene or graphite is made, for sealing function.The existing power transmission shaft with rolling bearing cooperation is direct mostly Assembling, without bushing, using long, power transmission shaft causes to wear and tear unavoidably, needs to dismantle, reinstalls and reuse after processing, existing Method easily causes the abrasion that there is increasing between bushing and axle, simultaneously because dismounting and maintenance cause operating efficiency to reduce, increases Plus production cost.

Utility model content

, mainly solving the technical problems that providing a kind of oil-free bushing, it is reasonable in design, structure is simple for the utility model, solution The problem of high cost in prior art of having determined.

For solving above-mentioned technical problem, the technical scheme that the utility model adopts is to provide a kind of oil-free bushing, its Including：Bush body and bearing body；Described bush body includes body, open-work and fixing groove；Described bearing body includes bearing, peace Dress hole and position guiding groove；Described bearing is located at one end of body, and bearing is structure as a whole with body；Described fixing groove is located at body The other end；Described open-work has four rows to be respectively distributed to the four direction all around of body；Described installing hole has four, respectively In four orientation of bearing chamfering；Described position guiding groove is located on two avris of bearing bottom.

Preferably, described open-work has four rows, and often row has four；

Preferably, described position guiding groove have two symmetrical with center line respectively.

The beneficial effects of the utility model are：The utility model structure is simple, easy to use, reduces coefficient of friction, dismounting With easy to process, saving time and using manpower and material resources sparingly, improve operating efficiency, reduces cost, increase the service life.

Brief description

Fig. 1 is a kind of schematic diagram of oil-free bushing of the utility model；

In accompanying drawing, the mark of each part is as follows：1st, body；2nd, bearing；3rd, open-work；4th, fixing groove；5th, installing hole；6th, lead position Groove.

Specific embodiment

Below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model Can be easier to be readily appreciated by one skilled in the art with feature, thus make apparent clear and definite to protection domain of the present utility model Define.

Refer to accompanying drawing 1, the utility model embodiment includes：Bush body and bearing body；Described bush body includes covering Body 1, open-work 3 and fixing groove 4；Described bearing body includes bearing 2, installing hole 5 and position guiding groove 6；Described bearing 2 is located at body 1 One end, and bearing 2 is structure as a whole with body 1；Described fixing groove 4 is located at the other end of body 1；Described open-work 3 has four rows to divide It is not distributed in the four direction all around of body 1；Described installing hole 5 has four, is located at four orientation of bearing 2 chamfering respectively On；Described position guiding groove 6 is located on two avris of bearing 2 bottom.

It is further that described open-work 3 has four rows, often row has four；

Be further, described position guiding groove 6 have two symmetrical with center line respectively.

When deployed, then just can bushing is solid by installing hole 5 as long as position is just easy to fix in by position guiding groove 6 Fixed；With bushing cooperation, pipe fitting can be docked by fixing groove 4 fixation and facilitate quickly.

The foregoing is only embodiment of the present utility model, not thereby limit the scope of the claims of the present utility model, every The equivalent structure made using the utility model description or equivalent flow conversion, or directly or indirectly it is used in other phases The technical field closed, is all included in the same manner in scope of patent protection of the present utility model.
