Abstract
The utility model discloses a compression ring, comprising a ring body, wherein an opening is formed in the ring body; the cross section of the ring body is of a wide-exterior narrow-interior wedge-shaped structure; a nylon lining layer is adhered onto the annular inner wall of the ring body; a nylon external protective sleeve layer is also adhered onto the annular outer wall of the ring body; protective films are respectively arranged on the upper surface and the lower surface of the ring body and two end faces of the opening in the ring body; each of the protective films consist of two layers, i.e. a phosphating film and an oxidation film. According to the compression ring, as the nylon protective layer and the protective films are arranged on the surface of the ring body, the abrasive resistance and the mechanical performance of the ring body are both improved, the abrasion is reduced, and the airtightness is also improved.
Description
Technical field
The utility model relates to the component on motor, is mainly a kind of compression ring.
Background technique
The main seal action of compression ring, makes gas leak phenomenon drop to bottom line, to improve the thermal efficiency, causes gas leakage, and sealing is poor.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of compression ring, and its surface at ring body is provided with nylon protective layer and protective film, and the wear resistance of ring body and mechanical property are all improved, and reduces wearing and tearing, has also improved sealing.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of compression ring; include ring body; on ring body, there is opening; it is characterized in that: the cross section of described ring body is wedge-shaped structure wide outside and narrow inside; on the ring inwall of described ring body, be stained with one deck nylon inner lining layer; on the ring outer wall of described ring body, be stained with one deck nylon outer sheath layer, on the two ends end face of the upper surface of described ring body and lower surface and ring body opening, be respectively equipped with protective film, described protective film is comprised of phosphating coat and patina double layer construction.
In the utility model, on the two ends end face of ring body upper surface, lower surface and ring body opening, be respectively equipped with protective film, phosphating coat is by chemically treated method, make piston ring surface produce one deck phosphating coat, when product is played to rust inhibition, also can improve the initial fitting property of ring; Patina is under the condition of high temperature and strong oxidizer, at steel material surface, generates layer oxide film, has corrosion resistance, the performance that anti-attrition is lubricated.
The utility model has the advantages that:
The utility model is provided with nylon protective layer and protective film on the surface of ring body, and the wear resistance of ring body and mechanical property are all improved, and reduces wearing and tearing, has also improved sealing.
Accompanying drawing explanation
Fig. 1 is plan view of the present utility model.
Fig. 2 is the sectional view of ring body in the utility model.
Embodiment
Referring to Fig. 1; a kind of compression ring; include ring body 1; on ring body, there is opening 2; the cross section of described ring body 1 is wedge-shaped structure wide outside and narrow inside, is stained with one deck nylon inner lining layer 3 on the ring inwall of described ring body 1, is stained with one deck nylon outer sheath layer 4 on the ring outer wall of described ring body 1; on the two ends end face of the upper surface of described ring body 1 and lower surface and ring body opening, be respectively equipped with protective film 5, described protective film 5 is comprised of phosphating coat and patina double layer construction.
