Description
Technical field
The utility model is related to piston technical field, and in particular to a kind of air compressor machine oil-free piston ring.
Background technology
Existing part air compressor machine is using there is oily piston, and friction temperature is high during piston rod movement；In prolonged exercise, piston
Lubricating oil is burned condensation, does not have lubrication, so as to aggravate the abrasion of piston rod；Increase piston rod and each parts it
Between gap, poor sealing performance shortens the service life of piston.In order to solve this technical barrier, prior art proposes nothing
Oily piston, piston face is provided with a polytetrafluoroethylene floor.
In the prior art, piston ring can produce abrasion when in use so that amount of heat is produced inside piston bush, therefore living
Plug ring is easily damaged after long term wear, causes sealing to be deteriorated, it is therefore desirable to change whole piston ring, and piston ring makes
Used time produces very big heat, if radiated not in time, can influence the normal operation of whole air compressor machine.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of by setting a Knockdown metal ring to be used as
Contact, can effectively reduce the abrasion with cast iron ring wall, conveniently replaced, cost-effective, and can greatly increase piston ring
The air compressor machine oil-free piston ring of sealing and thermal diffusivity.
The utility model is achieved through the following technical solutions：A kind of air compressor machine oil-free piston ring, including piston rod,
Piston bush and piston ring, piston bush are provided with pin-and-hole, piston bush and piston rod by together with pin connection, the piston ring it is interior
Wall, which is provided with the fixing groove of circle depression, fixing groove, installs a Knockdown metal ring, is set respectively at the two ends of fixing groove
A slot is equipped with, becket bends to arch shape and fitted with fixing groove inwall.
As preferred technical scheme, the becket is made up of elastic metallic material, and it is micro- after being installed in fixing groove
The convex inner bottom surface in piston ring.
As preferred technical scheme, it is provided with the becket in more than one hollow liquid storage cylinder, liquid storage cylinder
It is injected with the cooling oil of cooling.
As preferred technical scheme, the becket two ends are respectively arranged with an inserted link, and inserted link is inserted in fixation respectively
In the slot of groove both sides.
As preferred technical scheme, the opening of the becket rectifies the openend to piston ring, the length of the inserted link
Degree is equal to the depth of fixing groove, and becket inwall is close to piston ring inwall after inserted link is inserted in fixing groove.
The beneficial effects of the utility model are：The utility model is simple in construction, by setting a Knockdown metal ring
As contact, the abrasion with cast iron ring wall can be effectively reduced, replaceable becket after abrasion, further, since becket exists
Have substantial amounts of heat in liquid storage cylinder, therefore absorbable piston movement after installation, and there is elastic energy necessarily using elastic metallic
Power, and then greatly increase sealing.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the accompanying drawing used required in description of the prior art is briefly described, it should be apparent that, drawings in the following description are only
It is some embodiments of the present utility model, for those of ordinary skill in the art, is not paying the premise of creative work
Under, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is overall structure diagram of the present utility model.
Embodiment
All features disclosed in this specification, or disclosed all methods or during the step of, except mutually exclusive
Feature and/or step beyond, can combine in any way.
Any feature disclosed in this specification (including any accessory claim, summary and accompanying drawing), except non-specifically is chatted
State, can alternative features equivalent by other or with similar purpose replaced.I.e., unless specifically stated otherwise, each feature
It is an example in a series of equivalent or similar characteristics.
As shown in figure 1, including piston rod, piston bush and piston ring 2, piston bush is provided with pin-and-hole, piston bush and piston rod
By pin connection together, the inwall of piston ring 2 is provided with the fixing groove 4 of circle depression, and the interior installation one of fixing groove 4 is dismantled and assembled
Becket 1, slot is respectively arranged with the two ends of fixing groove 4, becket bends to arch shape and pasted with the inwall of fixing groove 4
Close.
In the present embodiment, becket 1 is made up of elastic metallic material, and dimpling is in piston ring after it is installed in fixing groove
Inner bottom surface, becket 1 is elastic component, due to the structure of dimpling so that can be in close contact after assembling with piston ring, in assembling
Also there is certain elastic compression power afterwards, and then increase sealing.
The cooling oil that cooling is injected with more than one hollow liquid storage cylinder 5, liquid storage cylinder 5 is provided with becket 1,
Amount of heat is absorbed by the cooling oil in internal liquid storage cylinder 5 when in use, preferably radiating is realized.
In the present embodiment, becket two ends are respectively arranged with an inserted link 3, and inserted link 3 is inserted in inserting for fixing groove both sides respectively
In groove, the opening of becket 1 rectifies the openend to piston ring 2, and the length of inserted link 3 is equal to the depth of fixing groove, inserted link insertion
Becket inwall is close to piston ring inwall after in fixing groove.
After becket 1 is inserted in slot by inserted link 3, you can complete assembling, the length of becket is equal to fixing groove
Length, therefore after inserted link is inserted in slot, that is, the assembling of becket is completed, it is very convenient, after abrasion, the lower metal of dismounting
Ring.
The beneficial effects of the utility model are：The utility model is simple in construction, by setting a Knockdown metal ring
As contact, the abrasion with cast iron ring wall can be effectively reduced, replaceable becket after abrasion, further, since becket exists
Have substantial amounts of heat in liquid storage cylinder, therefore absorbable piston movement after installation, and there is elastic energy necessarily using elastic metallic
Power, and then greatly increase sealing.
It is described above, embodiment only of the present utility model, but protection domain of the present utility model do not limit to
In this, any change or replacement expected without creative work should all be covered within protection domain of the present utility model.
Therefore, protection domain of the present utility model should be determined by the scope of protection defined in the claims.
