Abstract

The utility model discloses a piston ring steel belt combined oil ring of a bushing ring with a discharging function. The steel belt combined oil ring consists of a bushing ring with a discharging enhanced structure and two scrapper rings, either a trapezoid or a semicircular channel is additionally arranged on each wave-shaped platform in the whole circumference of an H-shaped wave-shaped bushing ring, the channels are communicated with discharging holes in the slope of a shoulder, and a surplus of lubricating oil scrapped from a cylinder wall can be more smoothly refluxed to a crankcase through the channels and the discharging holes, so that the mobility of the lubricating oil can be improved, and the failure of an oil control ring caused by the bonding between scrappers and the bushing ring due to the aggregation of sediments can be prevented; meanwhile, the carbon deposition cementation which is formed by combusting the lubricating oil in a combustor due to the ascending of the oil pressure can be avoided, so that the oil control capacity of the steel belt combined oil ring can be greatly improved, and engine oil consumption and exhaust gas emission can be effectively reduced; and the piston ring is longer in service life and stable and reliable in quality.

Description

A kind of piston ring steel belt assembled oil ring with excretory function structure H type grommet
Technical field
The utility model relates to a kind of improvement of engine piston ring backing ring of steel belt-combined oil ring structure, and it is applicable to various types of automobiles, motorcycle and universal machine internal-combustion engine piston ring, belongs to internal-combustion engine piston ring technical field.
Background technique
Along with social development, stricter Abgasgesetz is formulated in the countries in the world such as China and the U.S., European Union, Japan, more and more higher to automobile, motorcycle and component technical property requirements thereof, impel relevant technology and technique constantly improve, perfect.Piston ring steel belt assembled oil ring plays an important role to controlling combustion engine oil consumption and exhaust emissions, is a kind of more crucial component, and H type grommet is rational in infrastructure, process stabilizing, reliable performance, and has certain optimal design potentiality.The utility model is exactly on the basis of common H type grommet, increases for engine heat load, and oil temperature is more and more higher, easily produce cementing carbon distribution sediments, to the structure of H type grommet its lubricating oil flow that improved, improve control oiliness energy and the reliability thereof of steel belt assembled oil ring.
Summary of the invention
Task of the present utility model is improved the compound grommet of novel H type that strengthens excretory function structure in the structure of common H type grommet, more reasonable structure, and the mobility of lubricant oil is better, and lubrication oil consumption amount is less, more reliable performance.
Task of the present utility model completes in such a way, grommet and two doctor blade rings that it has enhancing draining structure by a slice form, the expansion cross section with enhancing draining structure grommet is the H mode type structure of connection, its each closed end is provided with a convex shoulder inclined-plane, and the axially support platform of this convex shoulder inclined-plane and grommet forms the convex shoulder angle of 20 ° ± 2 °; Doctor blade ring is the circular ring that has opening, be placed in respectively in the upper and lower flat surface of H type grommet and convex shoulder inclined-plane place, while being loaded into cylinder due to steel belt assembled oil ring, produce compression, make grommet produce elastic force, and by the effect at crossette place, elastic force is passed to doctor blade ring and act on cylinder wall.The combined altitudes minimum of combined oil ring of the present utility model can be accomplished 1.50mm, make the quality of ring have obvious reduction than the oil ring of other structures, and reduce inertial force, the tracing property of steel belt assembled oil ring to cylinder wall and the side seal of piston ring groove are strengthened like this.The more important thing is, the utility model piston ring steel belt assembled oil ring is to increase a trapezoidal or semicircular groove on each wave mode platform of the whole circumference of H type grommet, groove communicates with the drain boles at convex shoulder inclined-plane place, so not only increase the aisle spare between doctor blade ring and grommet, and ditch hole communicates, when engine operation, the unnecessary lubricant oil that doctor blade ring scrapes from cylinder wall can pass through groove, drain boles is back in crankcase more swimmingly, improve lubricating oil flow, preventing that sediments is gathered in produces cementing and causes oil control ring to lose efficacy between doctor blade ring and grommet, simultaneously, prevent Lubricating Oil press rise and on channel to firing chamber participate in burning form carbon distribution, thereby greatly improve the oil-control ability of steel belt assembled oil ring, effectively reduce engine oil consumption, also effectively reduce exhaust emissions, Service Life of Piston Ring is longer.
The utility model grommet design proposal is reliable, mould realization easy to manufacture, and manufacturing technology advanced person, product structure uniqueness, steady quality is reliable.

In Fig. 1-Fig. 8: 1-has the H type grommet that strengthens draining structure, 2-doctor blade ring, 3-grommet boss, 4-platform, trapezoidal or the semicircle drainage groove of 5-, 6-convex shoulder end face, 7-convex shoulder inclined-plane, the drain boles at 8-convex shoulder inclined-plane place, 9-grommet boss, the coupling part between the upper and lower boss of 10-
Embodiment
The piston ring steel belt assembled oil ring that adopts the utility model to make can obviously be found out from figure, and grommet (1) and two doctor blade rings (2) that internal-combustion engine steel belt assembled oil ring has enhancing draining structure by a slice form.Have and strengthen the grommet (1) of draining structure and select good thermal stability, austenitic stainless steel material that anti-corrosion capacity is high to make, after rolling finishing, just round coiling moulding, destressing processing, and through salt-bath nitriding, chromium plating or oxidation processes.This novel grommet feature of H type with enhancing excretory function is on the platform (4) between each wave mode boss (3) and convex shoulder inclined-plane (7), have a trapezoidal or semi-circular grooves (5), the drain boles (8) that groove (5) is located with convex shoulder inclined-plane (7) communicates.When engine operation, the unnecessary lubricant oil that doctor blade ring scrapes from cylinder wall can be back to crankcase more swimmingly by groove, drain boles, effectively reduces the consumption of machine oil.
The utility model has a significant effect for having improved lubricating oil flow, it can prevent that sediments is gathered between scraping blade and grommet and produces cementing, carbon distribution, particularly for the high motor of heat load, prevent Lubricating Oil press rise and on channel to firing chamber and participate in burning and form carbon distribution cementing sediments, thereby greatly improve the oil-control ability of steel belt assembled oil ring, effectively reduced engine oil consumption.
