Description
Technical field
The utility model relates to oil-scraping ring technical field, specially a kind of compressor oil-scraping ring.
Background technique
In engine piston ring assemblies, oil-scraping ring is set to the inside of cylinder sleeve, mainly undertakes the function of frizing, frizing effect
In terms of fruit depends primarily on following two: first is that the ring body of oil-scraping ring complies with the ability of the cylinder holes deformation of cylinder sleeve, i.e. oil-scraping ring phase
For the coating performance of cylinder sleeve；The on the other hand contact pressure between oil-scraping ring periphery and inboard wall of cylinder liner.Therefore, improve fitting
Performance, raising contact pressure can improve the frizing ability of oil-scraping ring；Oil-scraping ring is mainly used in oil-free lubricating piston formula pressure
Contracting machine, for preventing the lubricating oil in crankcase from entering cylinder, to achieve the purpose that compressed gas is oil-free.And currently, market
On oil leak is more serious at the scraper ring of piston compressor that uses, cause air compressor lubricating oil to consume, cause to waste.
Utility model content
(1) the technical issues of solving
In view of the deficiencies of the prior art, the utility model provides a kind of compressor oil-scraping ring, solves and leaks at oil-scraping ring
The problem of oil is more serious, seals defective tightness.
(2) technical solution
In order to achieve the above object, the utility model is achieved by the following technical programs: a kind of compressor oil-scraping ring, packet
Ring body is included, the ring body surface offers groove, and groove runs through ring body surface to inner peripheral, and the ring body side offers
Spring groove, the spring groove inner wall sleeve are equipped with spring, and ladder periphery is offered on the inside of the ring body, is opened on the inside of the ladder periphery
Equipped with groove, the spring both ends are fixedly connected by spring pull ring.
Preferably, the ring body surface opens up grooved hole.
Preferably, the groove number is six, and is uniformly arranged.
Preferably, the ring body bottom is provided with bottom end face.
Preferably, the groove covers at least 10 ° of angular range in ring body outboard peripheries.
Preferably, the ring body opens up seam.
(3) beneficial effect
The utility model provides a kind of compressor oil-scraping ring.Have it is following the utility model has the advantages that
(1), the compressor oil-scraping ring, oil-scraping ring is put into compressor, is typically used in compressor in the form of piston
, it is exactly in order to prevent in oil stream to piston, oil-scraping ring then belongs to packing seal, and majority is Copper alloy material, scrapes hydraulic fluid port phase
Crosshead side, two belong to a pair, and the groove compressor oil-scraping ring being arranged on the compressor with ring body oil-scraping ring of oil-scraping ring is just wrong
It opens, the scraping edge side in order to better seal, on the same compressor with ring body oil-scraping ring, in two scraping block outer top surfaces
To being contrary, simplify the manufacture craft of oil-scraping ring, also facilitate the installation of oil-scraping ring, by the ditch being arranged on oil-scraping ring
Slot enables the oil of end face to flow back in time, avoids oil-scraping ring relative rotation, solves the Leakage of oil-scraping ring.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the top view of the utility model；
Fig. 3 is the side view of the utility model.
In figure: 1 ring body, 2 grooves, 3 ladder peripheries, 4 slots, 5 springs, 6 spring pull rings, 7 grooves, 8 bottom end faces, 9 bullets
Spring slot, 10 seams.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-3 is please referred to, the utility model provides a kind of technical solution: a kind of compressor oil-scraping ring, including ring body 1, ring
1 surface of body offers groove 2, and groove 2 runs through 1 surface of ring body to inner peripheral, and 1 side of ring body offers spring groove 9, spring
9 inner wall sleeve of slot is equipped with spring 5, offers ladder periphery 3 on the inside of ring body 1, opens up fluted 7 on the inside of ladder periphery 3, and 5 liang of spring
Head is fixedly connected by spring pull ring 6.
1 surface of ring body opens up grooved hole 4.
2 quantity of groove is six, and is uniformly arranged.
1 bottom of ring body is provided with bottom end face 8.
Groove 2 covers at least 10 ° of angular range in 1 outboard peripheries of ring body.
