Abstract
The utility model relates to a piston ring. The surface of a piston ring body is provided with a chromium coating layer, the outer surface of which is provided with spongy reticulated mottles. The piston ring provided overcomes the shortcomings of slow heat conduction, uneven oil distribution, low rigidity and easy wear in a cylinder liner of the prior art. The benefits are as follows: the piston ring can economically and conveniently improve the working condition and product usability of the piston in the cylinder liner, lower the friction factor between the piston ring and the cylinder liner, is resistant to wear, can uniformly distribute oil, can store the lubricating oil by utilizing the chromium coating reticulated mottle groove on the piston ring surface, and can more uniformly distribute the lubricating oil in the reciprocating motion of the piston ring; and the piston ring also can greatly decrease energy consumption, meet the requirement of environment protection and increase the heat conduction property. The piston ring can increase the service lives of the piston and the cylinder liner by more than 3000 hours, increase the combustion motor power by more than 30%, save oil up to 25%, decrease the discharge air/smoke amount of the combustion motor, and decrease the environment protecting requirements of the air pollution.
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.
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.
Reach more than 3,000 hours the working life that the utility model has 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.
