Abstract
The invention relates to an automatic compensation device for piston ring scuffing. The device comprises a piston body and a piston ring, wherein the piston ring is located on the outer side of the piston body. The device is characterized by comprising a compensation pin, wherein a groove is formed in the piston body; the compensation pin is located inside the groove; an opening is formed in the radial direction of the piston ring; the front end of the compensation pin is located inside the piston ring opening; and a push force spring is connected to the rear part of the compensation pin.
Description
Technical field
The present invention relates to a kind of piston ring scuffing autocompensation installation.
Background technology
Piston ring uses on a variety of equipment, as air compressor, plunger hydraulic pump, internal combustion engine etc.Deng. Piston ring be on these equipment critical component, it plays very important on these equipmentEffect.
Piston ring is arranged on piston, plays sealing. Piston is driven in cylinder jacket the inside by bent axleOperation, along with moving up and down, that piston ring and piston have coordinated is air-breathing, compression, acting, exhaust meritEnergy. Piston ring is divided into two kinds of compression ring and oil rings, and what this patent related to is compression ring, the Main Function of compression ringSealing, cloth oil, conduction heat, guiding, support piston.
Piston ring ensures the sealing between piston and cylinder wall. When engine acting, stop in cylinderHigh temperature, high-pressure gas enter crankcase. Piston ring is in cylinder jacket up and down reciprocatingly when high-speed motion,The radial surface of piston ring can produce wearing and tearing, along with the wearing and tearing gradually of piston ring surface, and the opening of piston ringIt is large that mouth also progressively becomes. Mention above, piston ring seals, because opened gap increases graduallyGreatly, the sealing function of piston ring variation or disappearance gradually. High temperature, the high-pressure gas of cylinder the inside willScurry into crankcase by gap-clearance of piston rings, form lower exhaust, will make like this oil temperature raise, becomeDirty, rotten in advance. Meanwhile, machine oil enters combustion chamber and mixture combustion, forms burn oil state,Engine burn oil, also increases the consumption of machine oil and the formation of vapour carbon-deposits the cylinder. Carbon distribution is endangered to engineEvil is very large, and carbon distribution impurity also can enter in machine oil thereupon, causes increasing the wearing and tearing to running parts.Lower exhaust is large, also can cause an important parameter in engine--and compression ratio declines, this will make internal combustion engineBurn bad, cause engine output to decline.
Summary of the invention
Goal of the invention of the present invention is to provide a kind of piston ring scuffing autocompensation installation, canRealize the auto-compensation to piston ring scuffing.
Realize the technical scheme of the object of the invention:
A kind of piston ring scuffing autocompensation installation, comprises piston body, piston ring, piston ring positionIn the annular groove in piston body outside, it is characterized in that: also comprise compensation pin, annular groove on piston bodyBottom is provided with groove, and compensation pin is positioned at groove, and piston ring is radially provided with opening, before compensation pinEnd is positioned at gap-clearance of piston rings, and compensation pin rear portion is connected to thrust spring.
Gap-clearance of piston rings is triangular in shape, and corresponding compensation pin front end is triangular in shape.
Compensation pin front end face and piston ring outer edge surface maintain an equal level.
The beneficial effect that the present invention has:
Piston body of the present invention is provided with groove, and compensation pin is positioned at groove, and piston ring is radially provided with outMouthful, compensation pin front end is positioned at gap-clearance of piston rings, and compensation pin rear end is connected to thrust spring. CompensationPin front end face and piston ring outer edge surface maintain an equal level, and in the time of piston ring gauge wear, do at thrust springWith under, compensation pin can stretch out laterally, and piston ring scuffing is compensated, and can also prevent from livingPlug ring rotates. Ensure that gap-clearance of piston rings is all the time in best closed state, thereby make compressionThan remaining at ideal parameters, make that burning velocity is fast, sufficient combustion, engine outputLarger, economic performance is better. High temperature, high-pressure gas can not scurried into crankcase yet, and machine oil justTotally, reduce the wearing and tearing of machine well cuts to parts, make engine be in all the time good stateLower work, fully extends the maintenance cycle, reduces maintenance frequency, has also reduced maintenance cost,Service life and the service efficiency of internal combustion engine are improved.
Gap-clearance of piston rings is triangular in shape, and corresponding compensation pin front end is triangular in shape, be applicable to piston ring withWear-compensating pin coordinates, and can reach tensioning freely, makes piston ring and compensation pin all the time in closelyMated condition.
Brief description of the drawings
Accompanying drawing is structural representation of the present invention.
Detailed description of the invention
As shown in Figure 1, comprise piston body 1, piston ring 2, piston ring is positioned at piston body outsideIn annular groove, also comprise compensation pin 3, piston body annular groove bottom is provided with groove, and compensation pin is positioned at grooveIn, piston ring 2 is radially provided with opening, and compensation pin 3 front ends are positioned at gap-clearance of piston rings, compensationPin rear portion is connected to thrust spring 4. Gap-clearance of piston rings is triangular in shape, and corresponding compensation pin front end is triangleShape. Compensation pin front end face and piston ring outer edge surface maintain an equal level. The groove of piston body annular groove bottom is squareShape. Along with the wearing and tearing gradually of piston ring 2 radial surfaces and compensation pin 3 forward tip, in thrustUnder the thrust of spring 4, compensation pin 3 constantly stretches out from groove, groove play location,The effect of supporting and leading. Bent axle drives piston to move back and forth in cylinder, and piston ring 2 radiallySurface and the most advanced and sophisticated relative cylinder liners of compensation pin 3 constantly rub, make piston ring 2 radial surfaces withWear and tear gradually in compensation pin 3 tips, gap-clearance of piston rings progressively increases. Compensation pin 3 is at thrust spring 4Promotion under also gradually toward extrapolated, the triangle of compensation pin 3 leading portions all the time with gap-clearance of piston ringsClose contact, makes piston ring surface keep optimal seal state with cylinder sleeve all the time.
Compensation pin 3 can be installed by one compression ring, also can install by multiple tracks compression ring. The present invention is also sameTime be applicable to be provided with other plant equipment of piston ring.
