Abstract
Disclosed is a piston ring. The technical scheme includes that a chromium plated layer is arranged on the surface of the piston ring body, scattered-hole mesh is arranged on the outer surface of the chromium plated layer, and a tin plated layer is arranged on the outer surface of the scattered-hole mesh. The piston ring overcomes the shortages that the existing chromium plated piston ring is slow in heat conduction, uneven in oil distribution, low in hardness and easy in abrasion. The piston ring has the advantages that the piston ring can economically and conveniently improve working environments and product performance of pistons in cylinder bushes and reduce friction coefficient of the piston ring and the cylinder sleeve and is wear resistant; the piston ring is uniform in oil distribution by utilizing ribbed grooves on the chromium plated layer on the surface of the piston ring to store lubricating oil, thereby realizing more uniform distribution of lubricating oil under reciprocation of the piston ring; the piston ring can reduce energy consumption greatly and meet environmental protection requirements; and the heat conduction property is increased, thereby prolonging service life of the piton ring and the cylinder bush which can be over 3000 hours, increasing internal combustion engine power by over 30%, saving oil by 25%, overcoming mechanical abrasion of the piston ring in run-in period and obtaining better performance.
Description
Technical field
The utility model relates to a kind of internal-combustion engine piston ring.
Background technique
Piston ring is one of internal-combustion engine vital part, and the quality of piston ring performance characteristic directly influences the performance of motor, it major function be to seal, heat conduction, evenly distribute lubricant oil and support piston.Piston ring moves reciprocatingly in cylinder in company with piston, be one of worst parts of operating conditions in the motor, and the life-span is the shortest.Characteristics are, operating temperature high and under very high mechanical load high-speed slide, suffer strong wear.The performance that improves piston ring is the key that concerns the engine operation performance, hard chromium plating on the working surface of piston ring, though can improve surface hardness and wear resistance, piston ring heat conduction in cylinder sleeve is slow, easy to wear, the oily uneven shortcoming of cloth is the technical task that needs to be resolved hurrily.
Summary of the invention
In order to overcome the above-mentioned deficiency of prior art, the utility model provide a kind of wear-resistant, cloth is oily evenly, improve heat-conducting property, obviously improve the product usability, can lower energy consumption again, improves the piston ring of environmental protection efficacy.
In order to finish the foregoing invention purpose, the technical solution of the utility model is: on the surface of piston ring body one chromium coating is arranged, the outer surface of chromium coating has the porosity reticulate pattern, and the outer surface of porosity reticulate pattern has tin coating.
The utility model compared with prior art has following good effect:
1. can improve working environment and the product usability of piston in cylinder sleeve economical, easily, reduce the friction factor of piston ring and cylinder sleeve, wear-resistant, the working life of improving piston ring.
2. cloth oil evenly.Utilize piston ring surface chromium layer reticulate pattern groove, store lubricant oil, can more uniform distribution lubricant oil in the motion repeatedly of piston ring.
3. can cut down the consumption of energy greatly, and can reach environmental requirement.
4. raising heat-conducting property reduces the temperature of fastness.
The utility model is in order to solve the initial fitting property energy and the sealability of piston ring, on the basis of spongy chromium plating, on the porosity reticulate pattern of the piston ring of piston ring, apply tin coating, solved the mechanical wear of piston ring running-in period, to obtain more intact usability.Reach more than 3,000 hours the working life of having improved piston ring and cylinder liner compared to prior art, improves power of IC engine more than 30%, fuel-efficient up to 25%, can reduce the exhaust/cigarette amount of internal-combustion engine, reduces the environmental requirement of pollution of atmosphere.
