Abstract
The utility model provides a combined type tin plating piston ring which is mainly used for solving the problems of air mixing, oil mixing, poor wear resistance and the like of the piston ring. The piston ring comprises a first piston ring and a second piston ring which are arranged in a same ring slot and are combined for use, and gaps are formed on the first piston ring and the second piston ring. The combined type tin plating piston ring is characterized in that the included angles between the gaps and the end surface are 45 degrees, the thickness of the outer ring side of the first piston ring is one fifth of that of the inner ring side of the first piston ring, the thickness of the outer ring side of the second piston ring is five times of that of the inner ring side of the second piston ring, and the radiuses of inner circles and outer circles of the first piston ring and the second piston ring are equal; chromium layers are arranged on the outer surfaces of the first piston ring and the second piston ring, loose hole overlapping curves are arranged on the outer surfaces of the chromium layers, and tin plating layers are arranged on the outer surfaces of the loose hole overlapping curves. The combined type tin plating piston ring is widely used in the air cylinder of an automobile engine.
Description
Technical field
The utility model relates to the piston ring field, especially provides a kind of combined type zinc-plated 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, and its major function is 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.At present, the internal-combustion engine piston ring that adopts on the market is because the needs of assembling all are made into a metal cirque with fracture.Yet in long-term using process, the fracture slit of this metal cirque can be increasing, and then can influence sealing, control oil and the heat-transfer effect of internal-combustion engine, and inner cylinder pressure is reduced, and increased gas blowby, scurries oil, and amount has a strong impact on the stable of engine performance.And in use there is wear problem in piston ring; Through hard chromium plating on working surface at 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.Therefore, the piston ring that is used to seal, control oil and heat transfer effect is just to the operational efficiency of internal-combustion engine and whether can critical effect be arranged stable operation.
The model utility content
The purpose of the utility model is to provide a kind of can improve the motor sealability, and wear-resistant, cloth is oily evenly, a kind of combined type chrome plated piston ring of high thermal conductivity.
The utility model is for realizing that above-mentioned purpose adopts following technological scheme:
The zinc-plated piston ring of a kind of combined type; Comprise and be arranged on the first piston ring and second piston ring of setting up use in the same annular groove jointly; Be provided with the gap on the first piston ring and second piston ring, it is characterized in that: said gap and end face angle are 45 °, and said first piston ring outer rim side thickness is 1/5th of interior ring side; The said second piston ring outer rim side thickness is 5 times of interior ring side, and its interior circle radius of the first piston ring and second piston ring, exradius all equate; The said first piston ring and second piston ring face are provided with one deck chromium coating, and the outer surface of chromium coating is provided with the porosity reticulate pattern, and the outer surface of porosity reticulate pattern is provided with tin coating.
The 180 ° of settings of staggering each other of the said first piston ring and second piston ring gap.
The utlity model has following beneficial effect:
Because the utility model adopts above technological scheme, the said first piston ring and second piston ring can effectively carry out shutoff to its opened gap each other, have effectively reduced air leak amount; And owing on piston ring face, be provided with tin coating, reduced the friction factor of piston ring and cylinder sleeve, wear-resistant; Improved the working life of piston; And utilize piston ring surface chromium layer reticulate pattern groove, storage lubricant oil, lubricant oil more uniformly distributes in piston ring moves repeatedly.
