Abstract
A piston ring with inserted chrome-plated impregnate ceramic belongs to the technical field of piston ring, comprises a ring body and is characterized in that: the caulking groove is set on the excircle of the ring body and the ceramic impregnated chromium coating is set in the caulking groove. The thickness of the chromium coating is 0.06-0.60mm. The utility model is reasonable and simple in structure and can be manufactured easily. The ceramic impregnated chromium coating in the excircle groove of the piston ring increases the bond strength of the chromium coating and the ring body and avoids the spalling of the chromium coating. The sharp edge at the groove side strengthens the sealing performance of the piston ring and can reduce the consumption of the engine oil and the discharge of engine tailgas. The ceramic impregnated chromium coating basal body provides good abrasion resistance and non-brittleness and reduces frictional coefficient. No chromium coating sharp edges aside the groove avoids malignant friction of the cylinder walls, prolongs the service life of the engine and meets the requirement of high-performance engine for the piston ring.
Description
Technical field
The utility model relates to the structure of the piston ring that is used for automobile, motorcycle, belongs to the Sealing technical field.
Background technique
Piston ring is the vitals of motor, and the quality of piston ring directly has influence on the overall performance of motor.People have done many research work in order to improve the piston ring quality, have pair high wear resistance to study, have to pay attention to the high strength exploitation, and environmental protection, the envelope gas problem of solving arranged.For example, number of patent application is that the sprayed molybdenum on 02134426.4 piston ring surface is handled, and is will carry out surperficial sprayed molybdenum behind the piston ring nitriding treatment again to handle.The surface hardness of handling the back piston ring although it is so increases.Development along with industrial economy, high-power high performance motor is more and more higher to the requirement of piston ring, develops rapidly as automotive industry, and car speed is more and more faster, high-grade, high speed car requires to be equipped with high-power high performance motor, and the piston ring of conventional construction can not meet the demands.
The model utility content
The purpose of this utility model is exactly for satisfying the requirement in market, a kind of wear-resisting, anti-corrosion and good embedded chrome plating impregnated porcelain piston ring of envelope gas being provided.
The purpose of this utility model is achieved in that the embedded chrome plating impregnated porcelain piston ring, comprises ring body, it is characterized in that described ring body cylindrical is provided with embedding groove, is provided with the chromium coating that infiltrates pottery in the embedding groove, and the thickness of chromium coating is the 0.06-0.60 millimeter.
The utility model is rational in infrastructure simple, manufactures easily.Inlay in the piston ring excircle groove and ooze ceramic chromium coating, increased the adhesive strength of chromium layer and ring body, avoid the chromium layer to peel off, the trough rim sharp edge has been strengthened the performance of piston ring seal gas, can reduce oil consumption, reduces engine exhaust emission simultaneously.Pottery infiltrates chromium layer matrix, and wear-resisting property is good, and no fragility has reduced friction factor, and trough rim Chrome-free layer sharp edge avoided the pernicious friction to casing wall, prolongs the working life of motor, satisfies the requirement of high-performance enginer to piston ring.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is an A-A cross-sectional view among Fig. 1;
Among the figure: 1 ring body, 2 chromium coatings.
Embodiment
At the outer circumferential face car embedding groove of the piston ring ring body 1 of spheroidal graphite cast iron or alloy cast iron, chromium plating in embedding groove, the thickness of chromium coating 2 is the 0.06-0.60 millimeter.The chromium coating of the piston ring after the chromium plating is infiltrated pottery.
Claims (1)
