Abstract
The utility model relates to a piston ring, comprising a gas ring and an oil ring. The utility model makes a second gas ring composed of a double-layer outer ring, a double-layer inner ring and a side ring, and changes a second oil ring into a combined ring which is composed of a front ring and a rear ring, which enhances the sealing effect, extends the service life and thus improves the engine performance.
Description
The utility model belongs to field of internal combustion engine.
Piston ring is indispensable parts in the internal-combustion engine.Piston ring comprises compression ring and oil ring, is placed in the piston groove to fit tightly with cylinder body, plays the sealing knife-type oil stripping action.Since internal-combustion engine cylinder temperature height, pressure greatly, piston movement speed height in addition, therefore, piston ring scuffing is fast, working life is short.Because wear of piston-rings causes gas leakage, pressure of explosion is low, influences power, breathes heavily machine oil simultaneously, makes the piston face carbon deposit, causes the piston face scaling loss.
The purpose of this utility model is to provide a kind of can overcome above-mentioned shortcoming, simple in structure, easily the piston ring of making.
Technical solution of the present utility model is piston ring to be done combination improve.To compression ring, top compression ring is constant, adopts original compression ring.The second road compression ring changes three ring combinations into, by double-deck outer shroud, double-deck in ring, side ring forms, 120 ° of this three rings opening spaces are to oil ring, the first road oil ring changes into by preceding ring and back ring combination, and two encircle and mutually combine, and is respectively 105 ° and 75 ° with the bottom surface angle; The second road oil ring adopts original oil ring.If this piston originally had three road compression rings, then improve the available above-mentioned two road compression rings in back and get final product.
Advantages such as the utility model is compared with existing piston ring, and long service life is arranged, and motor easily starts, and power is big, and maintenance expenses is few.
Below in conjunction with accompanying drawing the utility model is further elaborated.
Accompanying drawing is the sectional drawing of piston and piston ring.1 is the top compression ring annular groove, and 2 is the second road compression ring annular groove, and 3 is the first road oil ring groove, and 4 is the second road oil ring groove, and F is a piston head.The top compression ring and the second road oil ring do not have improvement, do not draw so omit.The piston ring front view is a garden shape with piston ring is similar at present, and opening is arranged.A, B are enlarged view in the accompanying drawing.A is that the second road compression ring improves enlarged view, it is made up of double-deck outer shroud 5, double-deck interior ring 6, side ring 7, and the opening of three rings is spaced apart 120 °, and side ring 7 is near piston head F, double-deck outer shroud 5 and double-deck interior ring 6 are near side ring 7, double-deck outer shroud 5 presses double-deck interior ring 6, because the not overlapping and mutual extrusion of opening, so air leakage descends greatly, the double-deck outer shroud 5 of ring 6 extruding in double-deck simultaneously, life-span is increased, and above correlation can not change, otherwise inoperative.B is the first road oil ring enlarged view, it is made up of preceding ring 8, back ring 9, and the external diameter of preceding ring 8 is a bit larger tham back ring 9, and preceding ring 8 is near piston head F, ring 8 before back ring 9 presses, preceding ring 8 bottom surface angle α are 105 °, and back ring 9 bottom surface angle β are 75 °, because junction plane is the inclined-plane, therefore, because elasticity expands outwardly, Gu this, the life-span was longer when current ring 8 wore and tore.
Claims (3)
1, a kind of novel piston ring is made up of compression ring and oil ring, it is characterized in that:
(1). the second road compression ring is made up of double-deck outer shroud 5, double-deck interior ring 6, side ring 7.
(2). the first road oil ring is made up of preceding ring 8, back ring 9.
2, according to the said piston ring of claim 1, it is characterized in that the opening of the double-deck outer shroud 5 of the second road compression ring, double-deck interior ring 6, side ring 7 is separated by each 120 °, side ring 7 is near piston head F, and double-deck outer shroud 5 presses double-deck interior ring 6.
3, according to the said piston ring of claim 1, it is characterized in that the preceding ring 8 of the first road oil ring, bottom surface angle α, the β of back ring 9 are respectively 105 ° and 75 °, preceding ring 8 is near piston head F, and preceding ring 8 is the inclined-plane with back ring 9 junction planes.
