Abstract

The utility model relates to an energy saving wear-resisting integral combined piston ring oil ring, which comprises two doctor-bar convex rings (1)(2), a concave cushion(3) is sandwiched between the two doctor-bar convex rings(1)(2) and in combination with the two doctor-bar convex rings(1)(2). The inner and the outer circumferences of the concave cushion (3) are provided with an inner ring groove and an outer ring groove (4)(5) respectively. The utility model has reasonable design, integral structure, well wearing resistance, easy mounting and replacement, optimal sealed effect, simple structure, and easy manufacture, and can effectively enhance compression ratio of the combustion engine and prolong service life of the combustion. The utility model is a novel and practical integral piston ring oil ring.

Description

The integrated multiple-piece piston-ring oil ring of energy-saving wear-resistant

Technical field

The utility model relates to a kind of piston ring of internal-combustion engine, particularly a kind of integrated multiple-piece piston-ring oil ring of energy-saving wear-resistant that is loaded in the piston ring groove.

Background technique

The piston ring oil ring is to be contained in the annular groove of piston, usually the piston ring oil ring is split type, by on scrape loop, scrape loop down and grommet is formed, same being loaded in the annular groove, be combined into a piston ring oil ring, since on to scrape loop, scrape interface on the loop down be angle stake or directly mouthful, this structure produces seal defect inevitably, rush down problem such as leakage, causes the oily gas blowby of scurrying of internal-combustion engine, not only influence acting, also waste oil plant, bring pollution, and service life of engine is shortened dramatically; Because the upper and lower loop of scraping can be done relative movement, when particularly interface alignd, this phenomenon was especially outstanding.And it is a split-type structural, wears no resistance, and is cumbersome when installing and change, and wastes time and energy.

Summary of the invention

The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art and provides a kind of improved energy-saving wear-resistant integrated multiple-piece piston-ring oil ring, adopts monolithic construction, and convenient the installation and replacing improved sealing effect and working life.

The purpose of this utility model can realize by following technical measures: this piston ring oil ring is provided with two scraping blade bulge loops at least, be provided with recessed lining between the two scraping blade bulge loops, scraping blade bulge loop and recessed lining are connected as a single entity, the inside and outside circumference of recessed lining is respectively equipped with inside and outside annular groove, and circular groove plays the effect of oil trap, and recessed lining is provided with through hole and is communicated with inside and outside annular groove, through hole is spaced apart at recessed lining, the piston ring oil ring has interface, and interface forms dislocation between the scraping blade bulge loop, improves sealing effect.

The utility model is reasonable in design, adopts monolithic construction, and wear resistance is good, and it is convenient to install and change; Interface is a dislocation lap joint, and the sealing effect ideal can improve the compression ratio of internal-combustion engine effectively, prolongs service life of engine widely; And circular groove plays frizing and oil draining function, and it is simple in structure, and manufacturing is easy, is the one-piece piston ring oil ring of a Nover practical.

Description of drawings

Fig. 1 is a structural drawing of the present utility model;

Fig. 2 is the side view of Fig. 1.

Embodiment

With reference to Fig. 1, Fig. 2, this piston ring oil ring is circular, on having, following two scraping blade bulge loops [[1], [2], last, following scraping blade bulge loop [1], the recessed lining of one deck [3] is arranged [2], scraping blade bulge loop [1], [2] and recessed lining [3] be integrated, inner circumference at recessed lining [3] has interior circular groove [4], excircle has outer annular groove [5], in, outer annular groove [4], [5] be oil trap, in, outer annular groove [4], [5] be communicated with by through hole [6], through hole [6] is spaced apart at recessed lining [3], the interface of piston ring oil ring is last, following scraping blade bulge loop [1], [2] form dislocation between, be that piston ring oil ring interface is not last, following scraping blade bulge loop [1], [2] on the same vertical line, the dislocation interface connects by horizontal interface, improves sealing effect.According to level of processing and actual demand, this piston ring oil ring also can be multilayer scraping blade bulge loop structure.The overall structure of piston ring oil ring is made of metal, and integral installation is used in piston ring groove.

Claims
