Abstract
The utility model relates to a self-adjusting gap lubrication piston ring, constitute by the combination of the main ring of remaining silent and secondary ring, the internal diameter of the main ring of remaining silent equals with the secondary ring, the external diameter is also equal, there is a smooth circular truncated cone fitting surface and the storage lubrication groove of taking skirt form slot therebetween, plate porously chromium, thereby enable the piston ring to get into circumference O clearance state by oneself, can be with the piston ring, the piston ring groove, the clearance between the cylinder liner, automatically regulated arrives the minimum, there is not opening negative effect, and can store up more lubricating oil automatically, therefore, self-lubricate performance is better, sealing performance is better, the wearing and tearing of cylinder liner and piston ring are more even slow, each item performance index of engine further improves and improves, no longer take place early wear, gas leakage, the oil leak, phenomenon such as performance is not good enough, the technological difficult problem of puzzlement world engine field century has been solved.
Description
The utility model relates to the piston ring of engine art, especially can the lubricated piston ring of automatic gap adjusting.
Continue to use the engine piston ring in more than 100 year, adopted the mononuclear type hatch frame all the time.It is simple in structure, and fabrication and installation are convenient, but uses soon, and quick-wearing causes between piston and the cylinder sleeve poorly sealedly very much, and insufficient compression causes motor gas leakage, leakage of oil, declines of exerting oneself, and oil consumption rises, exhaust emission deteriorates, cold post-start difficulty after shutting down.This is mill morning, gas leakage, the leakage of oil Three Difficult Issues of puzzlement world car engine art a century.Before 2 years; two Chinese people from Henan have invented the major-minor dicyclo type opening piston ring that a kind of self oiling transfers the crack (prosperous good fortune group with its called after " prosperous good fortune ring "); making a breakthrough aspect the solution Three Difficult Issues first, thereby obtaining Chinese patent respectively and specified in its seven member states to enter the substantive protection stage by PCT in July, 1997 and in March, 1998.Because this " prosperous good fortune ring " is still opening (although opened gap and negative effect thereof are obviously dwindled), causes its blemish in an otherwise perfect thing, stay the next one can further improved defective.
The purpose of this utility model is that a kind of above-mentioned defective that do not have will be provided, promptly there is not the opening negative effect, every performances such as automatic gap adjusting is lubricated are better, cylinder sleeve and wear of piston-rings are more evenly slowly, working life and more the rering cycle longer, the self-gap-regulating lubricating piston-ring of phenomenons such as mill, gas leakage, leakage of oil, poor performance early no longer takes place.
Above-mentioned purpose of the present utility model is achieved in that
One, adopts the closed main ring structure.A, adopt lapping type closed main ring structure up and down: will show that the main ring two ends prolong in the type " prosperous good fortune ring ", the end Lower Half of pruning, the other end first half of pruning, two ends are joining and telescopic slide flexibly up and down.B, adopt the staggered cross-linking closed main ring structure of hyoid tooth will show that the main ring two ends prolong in the type " prosperous good fortune ring ", interlaced interting remains silent, and telescopic slide flexibly, and tongue bidentate cross-linking, two tongues, the three teeth cross-linking etc. that interlocks that interlock is arranged.C, employing bridge plate welding type closed main ring structure: will show the middle main ring two ends of type " the prosperous good fortune ring " first half and scabble; topped in the middle of the quilt neutral gear of pruning with bridge plate again; bridge plate one end and main ring one end are connected into one with solder flux, and can be on the main ring the other end telescopic slide flexibly.A, b, c, three get one.
Two, inner loop can adopt hatch frame, also can adopt the structure of remaining silent.The structural type of opening inner loop is with showing type " prosperous good fortune ring ", the same main ring of the structural type of the inner loop of remaining silent.Here, the compound mode of main ring and inner loop has and has only two kinds: a, closed main ring and opening inner loop; B, closed main ring and the inner loop of remaining silent.No matter which kind of compound mode, having main ring in the two at least at main ring and inner loop is the employing structure of remaining silent.
Three, a smooth truncated cone fitting surface and an oil storage sump arranged between closed main ring and the inner loop.Main ring equates that with the internal diameter of inner loop external diameter also equates.
Four, adopt the oil storage sump structure of band skirt shape chase.Except that being located at unfilled corner place, the truncated cone face outside, also can be located at respectively on the inside and outside circle cylinder of main ring and inner loop.
Five, adopt plating porous metal chromium surface structure.
Because adopt above-mentioned a series of innovation structures, the utility model will obtain following good effect:
One, self oiling performance is better.The utility model can not only self oiling, oil storage sump is not only arranged, and have skirt shape chase and plate porosity chromium, so can store up and receive more lubricating oil, the self oiling performance is more superior, cylinder sleeve and wear of piston-rings more evenly slowly, working life and more the rering cycle prolong more, phenomenon no longer takes place to grind morning.
Two, sealability is better.Smooth truncated cone fitting surface allows the ingenious structure of small slippage between the utility model employing closed main ring and the inner loop, so can make piston ring from being advanced into circumferential O gap state, gap between piston ring, piston ring groove, the cylinder sleeve can be adjusted to minimum value automatically, no longer allowing small ventilative oily opened gap exists, therefore sealability is better, and the gas leakage oil leakage phenomenon no longer takes place.
Three, in addition, lubricating oil consumption further reduces, toxic emission and environmental pollution further improve, operating noise further weakens, the every performance index of motor further improve, and have satisfactorily resolved the difficult scientific problems such as mill morning, gas leakage, leakage of oil, poor performance of puzzlement world engine art a century.
The utility model is described in further detail with implementing side below in conjunction with accompanying drawing.
Fig. 1 is traditional mononuclear type opening piston ring plan view, and Fig. 2 is its plan view.
Fig. 3 is existing type " prosperous good fortune ring " (crack major-minor dicyclo type opening piston ring is transferred in an existing type selflubricating) plan view, and Fig. 4 is its plan view.
Fig. 5 is the innovation I type self-gap-regulating lubricating piston-ring plan view that constitutes of lapping type structure closed main ring and opening inner loop up and down, and Fig. 6 is its plan view.
