Abstract
The utility model relates to a gaseous ring of a small air cooling engine. The utility model has the structure that multichip overlapped piston rings are used, the longitudinal thickness sum of the multichip overlapped piston rings is equal to the thickness of an original monolithic gas ring, the multichip overlapped piston rings are matched with a piston ring groove, each piece of piston ring is a barrel face ring, and openings of the multichip overlapped piston rings are staggered each other. The utility model has the advantages that the sealing performance of the gaseous ring can be enhanced, the friction force of the gaseous ring and a cylinder wall can be reduced, the rate of wear of the gaseous ring and the cylinder wall can be decelerated, the service lives of the cylinder and the piston ring can be prolonged, and the power performance and the economy of the small air cooling engine can be enhanced.
Description
The utility model relates to compact internal combustion engine design and manufacturing field, the compression ring of especially small-sized air cooling engine piston.
The compression ring of present small-sized air cooling engine all adopts the monolithic whole piston ring.Because the rotating speed of small-sized air cooling engine is very high, the average running speed of piston is very high, and because air-cooled cooling effect is not so good as liquid cooling, so cylinder wall temperature is higher, the lubricant film on casing wall surface is relatively poor, these all make the piston ring of small-sized air cooling engine and cylinder wear fast, and both wear and tear big after, must cause that the end-gaps of ring strengthens, the combustion gas of leaking from the ring opening will increase, the power, the moment of torsion that cause motor descend, and oil consumption is risen, starting difficulty.For four stroke engine, also can cause lubricating oil carry-over, blowdown be increased, because compression ring, the second road compression ring particularly, have the effect of scraping casing wall machine oil concurrently, and, cause that the end-gaps of ring strengthens in case the ring wearing and tearing strengthen, the frizing ability drop, make the machine oil on the residual casing wall of part scurry into cylinder, nonflammable because of machine oil, discharge with waste gas.
The purpose of this utility model is to improve the sealing of compression ring, reduces the frictional force of ring and cylinder wall, slows down the rate of wear of encircling with cylinder wall, prolongs the working life of cylinder and piston ring, improves power character, the Economy of small-sized air cooling engine.
The technical solution of the utility model is that compression ring adopts the superimposed piston ring structure of multi-disc, the multi-disc piston ring equal the longitudinal thickness of former monolithic compression ring perpendicular to the longitudinal thickness sum of anchor ring, be complementary with piston ring groove.The specification of every piston ring is identical, is a barrel face ring, and the opening of multi-disc piston ring staggers each other.Can adopt the superimposed piston ring of biplate to make compression ring or adopt three superimposed piston rings to make compression ring.
The beneficial effects of the utility model are
1. because of adopting its opening of the superimposed piston ring of multi-disc to stagger each other, strengthen sealing, eliminated the influence that the monolithic gap-clearance of piston rings brings, prevented gas leakage;
2. owing to adopt the superimposed piston ring of multi-disc, the elastic force of ring reduces, and because less amount of lubrication oil can be deposited in the gap between ring and the ring, the ring and the frictional force of cylinder wall are reduced, frictional loss just reduces, the power character of motor, Economy improve, and the rate of wear of ring and cylinder wall slows down in addition, and the life-span increases.
3. the elastic force of ring reduces, and the envelope gas of ring, frizing ability (concerning four stroke engine) are reduced, but owing to adopt multi-disc superimposed, the road number that is equivalent to compression ring increases, and the opening sealing strengthens significantly, so this ability is compensated, can not reduce, only can strengthen.
4. because the specification unanimity of piston ring can be simplified production technology, boost productivity, be convenient to production management and reduce cost.
The drawing explanation
The superimposed piston ring of Fig. 1 biplate is made compression ring figure
The 1--cylinder block
The 2--cylinder liner
The superimposed piston ring of 3--biplate
The 4--piston
5--corrugated gasket (two stroke engine does not have)
6--scraping blade oil ring (two stroke engine does not have)
Three superimposed piston rings of Fig. 2 are made compression ring figure
Three superimposed piston rings of 7--
Embodiment:
The superimposed piston ring of biplate is made compression ring: the size of piston does not make any changes, and piston ring encircles outer surface chromium plating with senior spring steel manufacturing, and ring thickness equals 1/2nd of former monolithic ring, and the specification of each ring is identical, is bucket face ring.As shown in Figure 1.
Three superimposed piston rings are made compression ring: the size of piston does not make any changes, and piston ring encircles outer surface chromium plating with senior spring steel manufacturing, and ring thickness equals 1/3rd of former monolithic ring, and the specification of each ring is identical, is bucket face ring.Be illustrated in figure 2 as three superimposed piston rings and make the example schematic that compression ring is used on the 152FM four stroke engine, receive good practical effect.
