Abstract
The utility model relates to a combined piston ring which is suited to be served as a gas ring on a reciprocating piston engine. Each group of the combined piston ring of the utility model is composed of a main ring (1) and an auxiliary ring (2). The cross sections of the main ring (1) and the auxiliary ring (2) are both wedge-shaped, and the main ring and the auxiliary ring are combined by an inclined plane. Opening positions are staggered for 180 DEG after the combined piston ring is provided, and an inner cutting table (3) with an upper side is arranged on the auxiliary ring (2). Air leakage of a direct opening is avoided by the combined piston ring of the utility model, air leakage of a side clearance and air leakage of fluttering can be reduced, machine oil is saved, abrasion is reduced, and a ring change period is prolonged.
Description
The utility model relates to a kind of multiple-piece piston-ring, is suitable for doing the compression ring on the conventional engine.
As everyone knows, piston ring is the strength member on the motor, and its sealing effect has a significant impact engine performance.
Gas leakage has three kinds of forms usually during engine operation: opening gas blowby, sideshake gas blowby, vibration gas blowby.For improving the performance of motor, it is necessary to take measures to reduce three kinds of gas leakage.
The seal action of piston ring also shows the control aspect to lubricant oil.In general, the second road compression ring is being born the effect that forms lubricant film on cylinder bearing face with oil ring during engine operation, if the oil sealing effect of the second road compression ring is bad, machine oil will be scurried into combustion chambers burn, causes the rising of oil consumption.And the partial combustion of machine oil had both made oxious component increase in the engine emission, and the carbon deposit of its formation serves as abrasive grains again, quickens the wearing and tearing of correlated parts.
The wearing and tearing of piston ring and annular groove are problems that is difficult for overcoming always.The wearing and tearing of piston ring excircle face cause opened gap to increase, and the wearing and tearing of piston ring side and annular groove cause the side clearance to increase, and the appearance of all these phenomenons all makes motor gas leakage serious, degradation, thereby necessary maintenance, the part that more renews.
This is suitable for novel purpose and is to overcome poor, the problem such as wear no resistance of piston ring packing, and a kind of new multiple-piece piston-ring is provided, and reaches with its rational structure to strengthen the effect that seals, increases the service life, reduces mechanical loss.
This is suitable for novel purpose and realizes as follows:
Multiple-piece piston-ring by main ring with pay two on ring and constitute, main ring is wedge shape with a cross section of paying ring, the two is with the inclined-plane combination, and after-opening position 180 degree that stagger are installed, and pays ring and has upper side inscribe platform.This novel multiple-piece piston-ring that provides is provided had both been avoided direct opening gas leakage, can alleviate sideshake gas leakage, vibration gas leakage again, and save machine oil, reduces wear, and has prolonged the ring change cycle.
Below in conjunction with accompanying drawing the utility model is described in detail.
The sectional arrangement drawing of the multiple-piece piston-ring that Fig. 1 provides for foundation the utility model.
Fig. 2 is the cross section enlarged view of the inner loop of piston ring shown in the accompanying drawing 1.
Fig. 3 is the cross section enlarged view of the main ring of piston ring shown in the accompanying drawing 1.
As shown in drawings, every group of described multiple-piece piston-ring by main ring (1) with pay ring (2) two formations, main ring (1) is wedge shape with a cross section of paying ring (2), the two is with the inclined-plane combination, after-opening position 180 degree that stagger are installed, are paid ring (2) and have upper side inscribe platform (3).
The inclined-plane of main ring (1) is towards the firing chamber, and the inclined-plane of pair ring (2) is the firing chamber dorsad.
Main ring (1) periphery (4) area encircles (2) periphery (5) area greater than paying, and main ring (1) periphery (4) is the surface of cure process.
During installation, there is not direct opening in main ring (1) and an aperture position of paying ring (2) 180 degree that stagger on whole circumference, effectively reduce the opening gas blowby.
Main ring (1) is analogous to the wedge type ring in the common ring, pay ring (2) and have upper side inscribe platform (3), like this, after being installed in the annular groove, main ring (1) all takes place just to twist with a pair ring (2), make the upper and lower bi-side of associative ring and annular groove that tight line all take place and contact, effectively reduce sideshake gas leakage and vibration gas leakage.
Because main ring (1) all takes place just to twist with a pair ring (2), makes associative ring have the function of up cloth oil, descending frizing, has effectively reduced machine oil scurrying into to the firing chamber.
It is wear-resistant that special construction of the present utility model has determined that it also has, the advantage of long service life:
At first, main ring in the multiple-piece piston-ring (1) all belongs to slim ring with a pair ring (2), and quality own is less, inertial force is less in the high speed to-and-fro motion, and life period is poor on the two motion phase, interfere with each other,, alleviated the wearing and tearing of ring side and annular groove so the impact of annular groove is obviously reduced.
Secondly, because periphery (4) area of main ring (1) is greater than periphery (5) area of paying ring (2) in the multiple-piece piston-ring, and main ring (1) periphery (4) is the surface of cure process, so the two wearing and tearing is asynchronous, pay the wearing and tearing that ring (2) wearing and tearing are greater than main ring (1), at this moment, main ring (1) and pair ring (2) are in the radially occurrence positions changing of the relative positions, the degree of multiple-piece piston-ring is increased, remedied the wearing and tearing of ring side and ring groove surface.The sideshake compensate function of this ring often remains within the more appropriate scope sideshake, has prolonged working life.
The 3rd, because the main ring (1) of the utility model piston ring along the inclined-plane radially relative movement takes place with a pair ring (2) when motion state, make sideshake in continuous variation, reach the effect of getting rid of carbon deposit, help alleviating the wearing and tearing of ring and annular groove.
Studies have shown that the mechanical loss power of motor has 75% from the frictional force between piston ring and the cylinder.The pot type piston ring often needs bigger radical elasticity in order to obtain the better seal effect, and this has just increased the frictional force between piston ring and the cylinder.Adopt the utility model piston ring, but can use less radical elasticity, and not influence its sealing.In addition, in the utility model multiple-piece piston-ring, main ring (1) all has the frizing ability with a pair ring (2), can have some machine oil in the gap between the two, has improved the lubrication state of working surface.Above two make that all frictional force reduces, mechanical loss power reduces.
The utility model piston ring produces following good result through the installation test:
1, fuel consumption rate, oil consumption descend, and air leakage reduces.
2, output power increases, and mechanical loss power reduces.
3, engine emission obviously improves.
4, long service life.
Evidence, the utility model piston ring can obviously improve Economy, the power character of motor, improves the discharging of motor, has tangible economic benefit and social benefit.
