Abstract
The utility model relates to an engine cylinder liner, which is mainly applicable to use on vehicle bodies of an automobile, a motorcycle and the like. The structure thereof is as follows: the inner surface of a cylinder body is provided with a plating layer, and the outer surface thereof is provided with a spraying layer. The engine cylinder liner improves the rigidity and the intensity thereof, leads the surface thereof to be smoother and more applicable, prolongs the service life, improves the abrasive resistance and anti-corrosion performance thereof, and guarantees good sealing performance among a piston, a piston ring and the cylinder liner, thus avoiding the occurrence of the oil pumping phenomenon.
Description
Technical field
The utility model relates to a kind of cylinder sleeve, relates in particular to a kind of cylinder sleeve of engine, mainly is applicable on the car bodies such as automobile, motorcycle and uses.
Background technique
Cylinder sleeve is the abbreviation of cylinder liner, is installed in the cylinder barrel of cylinder body, forms the firing chamber jointly with piston and cylinder cap.Cylinder sleeve is divided into dry sleeve and wet sleeve two big classes.The back side of dry sleeve does not contact cooling water, and the back side of wet sleeve contact cooling water.Dry sleeve thinner thickness, simple in structure, easy to process.Wet sleeve directly contacts cooling water, so help the cooling of motor, helps the miniaturization and of motor.The cylinder sleeve that chooses, be to guarantee the normal prerequisite of using of motor, if liner backs can not be fitted well with body sleeve port internal surface, the heat transfer of cylinder sleeve will be influenced, cause cylinder sleeve, piston, piston ring heat load too high, and this situation does not reflect that with the water-thermometer thermometric cylinder sleeve gets actual temperature, therefore will accelerate the carbon distribution and the snap ring of piston ring groove machine oil, in working order down, can't guarantee to obtain excellent sealing performance between piston, piston ring, the cylinder sleeve, early stage lubricating oil carry-over phenomenon will unavoidably take place; And cylinder sleeve of the prior art mainly contains Cast iron liner, metallurgical cylinder cover and stainless steel cylinder sleeve, and the Cast iron liner manufacture cycle is long, and amount of finish is big, and stock utilization is low; Metallurgical cylinder cover then needs special device production, and cost is higher; It is more that the stainless steel cylinder sleeve then adds the man-hour clout, and stock utilization is low.At present, above-mentioned cylinder sleeve all is difficult to satisfy the cylinder sleeve that uses on the motors such as automobile, motorcycle, to performance demands such as intensity, hardness, wear resistance and corrosion resistancies.
The model utility content
The utility model is at above-mentioned problems of the prior art, through a large amount of test with do painstaking research, cylinder sleeve structure of the prior art is improved, a kind of cylinder sleeve of engine is provided, cylinder sleeve wear resistance and the relatively poor problem of corrosion resistance in the prior art have been solved, and the utility model intensity and hardness are higher, easy access, maintenance.
The technical solution of the utility model is as follows:
The internal surface of cylinder body is provided with coating, and the outer surface of cylinder body is provided with sprayfused coating.
Described coating is nickeling layer.
Described sprayfused coating is the metal anti-corrosive paint layer.
The utility model has the advantages of as follows:
1, by inside coating is set, has improved hardness of cylinder and intensity, make its surface Paint Gloss suitable, prolonged shelf life.
2, outer installment anticorrosive coat has improved the wear resistance and the anticorrosive property of cylinder sleeve, has guaranteed excellent sealing performance between piston, piston ring, the cylinder sleeve, has avoided scurrying the generation of oily phenomenon.
3, liner backs and body sleeve port internal surface are fitted well, strengthen the conduction heat transfer performance.
4, easy access, maintenance, cost is low, and operation is convenient.
5, simple in structure, be easy to realize, remarkably productive, be suitable for applying.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure, 1, cylinder body, 2, coating, 3, sprayfused coating.
Embodiment
The utility model in conjunction with specific embodiments, it is as follows to be elaborated.
Embodiment
According to the size requirement of different cylinder sleeves, select the steel plate of corresponding size, by blanking, reel, welding, to remove leftover pieces and make cylinder body 1, the internal surface chromium plating of cylinder body 1 forms nickeling layer 2; The outer surface metalizing anticorrosive paint of cylinder body 1 forms metal anti-corrosive paint layer 3.
The utility model is not limited by specific embodiment, is as the criterion with claims.
Claims (3)
1. a cylinder sleeve of engine is characterized in that the internal surface of cylinder body (1) is provided with coating (2), and the outer surface of cylinder body is provided with sprayfused coating (3).
2. cylinder sleeve of engine according to claim 1 is characterized in that described coating (2) is nickeling layer.
3. cylinder sleeve of engine according to claim 1 is characterized in that described sprayfused coating (3) is the metal anti-corrosive paint layer.
