Abstract
The utility model relates to a clamp spring type piston ring. The clamp spring type piston ring is a lower piston ring which is used with an upper piston ring mounted on a piston in matched mode, and when the upper piston ring is worn to cause power reduction, the clamp spring type piston ring starts to work. The clamp spring type piston ring comprises an upper lateral face (18) of the front of the ring, a rear lateral face lower gas-leakage stopping plate (20), an upper left gas-leakage stopping plate (13), an upper right gas-leakage stopping plate (14) and a clamp spring assembly (1). By means of the clamp spring type piston ring, the upper piston ring can be replaced automatically, and when the upper piston ring is worn to cause the power reduction, the lower piston ring starts to work. When an upper elastic plate of the clamping spring assembly of the lower piston ring is worn out till the upper elastic plate breaks, the lower piston ring can still work normally, and therefore the replacement time of the piston can be prolonged, work efficiency can be improved, and fuel consumption can also be lowered.
Description
Technical field
The present invention relates to the engine fittings field, especially relate to a kind of circlip type piston ring.
Background technique
Piston ring is the core component of fuel engine inside, it and cylinder, and piston, cylinder wall etc. are finished the sealing of fuel oil-gas together.The piston ring effect comprises sealing, adjusting machine oil (control oil), heat conduction (heat transfer), guiding (supporting) four effects, so piston ring plays very important effect in motor.The power that acts on piston ring has gas pressure, encircle self elastic force, encircle the frictional force of reciprocating inertial force, ring and cylinder and annular groove etc.Because the effect of these power, ring will produce the basic exercises such as axial motion, radial motion, rotation motion; In addition, piston ring is because its movement characteristic is accompanied by irrgular movement, floating outstanding and axial vibration that axial irrgular movement causes, radially irrgular movement and vibration, torsional motion etc. occur inevitably, and these irrgular movement meetings damage piston rings.
New engine is through using back piston ring opened gap to increase gradually, and when opened gap during greater than the limiting value of regulation, compression ring gas leakage, compression pressure without combustion reduces, and engine power descends, oil ring and compression ring frizing ability variation, and machine oil is consumed above set limit.When piston ring gap reaches the maximum limit of regulation, need more rering.
And because at present motor can only disposable installation fitting, such as piston ring, cylinder sleeve all is disposable installation, can not automatically change.Since can not automatically change accessory, piston ring, piston, after cylinder sleeve was worn, power descended, and fuel consumption increases, and motor self can not address this problem automatically.
Summary of the invention
The present invention will address the above problem exactly, and a kind of circlip type piston ring novel, that can automatically change is provided.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of circlip type piston ring is characterized in that, this circlip type piston ring is the lower piston ring, and it and the upper piston ring that is installed on the piston support the use; When the wearing and tearing of upper piston ring cause power to descend, this circlip type piston ring starting; Described circlip type piston ring comprises hold one's breath under the front upper side 18 of ring, the trailing flank plate 20, the upper left plate 13 of holding one's breath, upper right plate 14 and the jump ring assembly 1 of holding one's breath; Have machine oil outlet 21 in the front upper side 18 of ring, holding one's breath under the front upper side 18 of ring and trailing flank between the plate 20 is intermediate groove 19; Be provided with oil gas distance piece 22 between the plate 14 upper left hold one's breath plate 13 and upper right holding one's breath, at the upper left plate 13 and upper rightly hold one's breath that the part with respect to the 22 more close gap-clearances of piston rings of oil gas distance piece arranges jump ring fit 16 between the plate 14 of holding one's breath, be provided with jump ring bumping post groove 17 in jump ring fit 16; In gap-clearance of piston rings jump ring assembly 1 is set partly, gap-clearance of piston rings partly the contiguous upper left plate 13 of holding one's breath, upper right plate 14 sides of holding one's breath are threeway grooves 15, jump ring assembly 1 is contained in the jump ring bumping post groove 17 of jump ring fit 16 through threeway groove 15; Plate 20 sides of holding one's breath under the front upper side 18 of gap-clearance of piston rings part adjacent loops, trailing flank are convex plate bottom right plate 9 and the convex plate bottom left plates 10 of holding one's breath of holding one's breath of holding one's breath of holding one's breath, hold one's breath the convex that the is across gap-clearance of piston rings platform 12 before the plate of holding one's breath is set between the plate 10 in convex plate bottom right plate 9 and the convex plate bottom left of holding one's breath of holding one's breath of holding one's breath, the fixing aperture 8 of stern post after platform 12 is provided with before convex is held one's breath plate; Convex plate bottom right plate 9, convex the hold one's breath plate 10, convex of plate bottom left of holding one's breath of holding one's breath of holding one's breath holds one's breath that platform 12 consists of the shape of falling n structures before the plate, be somebody's turn to do the radial thickness of the shape of falling n structure less than the radial thickness of plate 20 of holding one's breath under the front upper side 18 of ring, the trailing flank, and it is step-like to encircle plate 20 formation of holding one's breath under front upper side 18, the trailing flank; Hold the intermediate projections plate 11 of holding one's breath in this shape of falling n structure, the hold one's breath part of plate 11 of intermediate projections enters in the described intermediate groove 19; Described jump ring assembly 1 comprises upper elasticity plate 2 and down spring plate 4, up and down elastic plate isolation seam 7 is arranged between two elastic plates, the length of down spring plate 4 is less than the length of upper elasticity plate 2, tail fixing column 6 after an end of upper elasticity plate 2 arranges, rear tail fixing column 6 is embedded in hold one's breath fixing 8 li of apertures of rear stern post on the front platform 12 of plate of convex, the end that the other end of upper elasticity plate 2 is connected with the down spring plate is in up and down elastic plate connection microcephaly 3 places connection, the other end of down spring plate 4 is provided with jump ring bumping post 5, and jump ring bumping post 5 and jump ring bumping post groove 17 cooperate.
Beneficial effect of the present invention: can be automatically rering more, when the wearing and tearing of upper piston ring cause power to descend, the starting of lower piston ring.The upper elasticity plate of the jump ring of lower piston ring and cylinder bore wall contact wear, until fracture, then the lower piston ring normally moves, and can prolong the repair time like this, can also increase working efficiency, reduces oil consumption.The jump ring technology can be installed in and also can be installed on the Tu Aoshi seal ring on the neat mouthful of conventional ring.The existing compression ring function of the design of this circlip type piston ring has again the oil ring function, and the intermediate groove of ring body can play the function of scraping filter oil, and the machine oil of being scraped filter pushes sump by the machine oil outlet.The compression ring sealing: the front upper side of ring and cylinder sleeve fitted seal, the downside of trailing flank and piston cell wall fitted seal, the plate of holding one's breath of adding the termination cooperates compression ring to form sealing.
