Abstract

The utility model discloses an improved wear-resisting piston ring. The improved wear-resisting piston ring comprises a piston ring main body, wherein two side surfaces of the piston ring main body are sliding surfaces; convex parts are formed in the upper part and the lower part of the piston ring main body along the inner circumferential face; each convex part comprises a group of upper convex pieces and a group of lower convex pieces; groove parts are formed in the inner side face of the piston ring main body between each upper convex piece and the corresponding lower convex piece; a wear-resisting layer is coated on the surface of each groove part; a spraying base layer is formed on each sliding surface; a spraying surface layer is formed outside each spraying base layer. According to the improved wear-resisting piston ring, the convex parts are formed in the upper part and the lower part of the piston ring main body along the inner circumferential face; the convex parts have the supporting effect and manganese-titanium alloy wear-resisting layers are coated on the surfaces of the groove parts, so that the improved wear-resisting piston ring has the good wear resistance; the piston ring is not easy to deform and the service life is long.

Description

A kind of improved abrasion-proof piston ring

Technical field

The utility model relates to a kind of piston ring, relates in particular to a kind of improved abrasion-proof piston ring.

Background technique

Be accompanied by high output and the high performance of internal-combustion engine, it is more and more harsher that the Environmental Conditions of the slide members such as piston ring becomes, thereby require to have good wear resistance, the slide member of sealing.Piston ring is installed on piston, for realizing the level and smooth to-and-fro motion of piston in cylinder.Piston in internal-combustion engine, working pressure ring and oil ring are as piston ring conventionally, and oil ring can enter to have sealing to high-temperature combustion gas; Pressure ring plays guided bearing effect.The wear resistance of piston ring and sealing depend primarily on the slip surface of piston ring, and slip surface contacts the sex change producing with cylinder, cause piston ring packing lower.Therefore, need to provide a kind of new technological scheme to solve the problems referred to above.

Model utility content

The purpose of this utility model is to provide a kind of good sealing effect, on-deformable improved abrasion-proof piston ring.

The technical solution adopted in the utility model is:

Improved abrasion-proof piston ring, comprise a piston ring main body, these piston ring main body bi-side are slip surface, the upper and lower of described piston ring main body is all formed with protuberance along inner peripheral surface, described protuberance comprises male member and one group of lower convex member on one group, and the piston ring main body inner side surface between described upper male member and lower convex member has slot part, and described slot part surface is coated with wearing layer, on described slip surface, form a spraying base layer, the outer sprayed surface layer that forms of described spraying base layer.

Described wearing layer is manganese-titanium layer.

Described spraying base layer is molybdenum-copper layer.

Described sprayed surface layer is albata layer.

The shape of cross section of described protuberance is square.

The beneficial effects of the utility model: the upper and lower of the piston ring main body that the utility model adopts is all formed with protuberance along inner peripheral surface, this protuberance plays supporting role, slot part surface is coated with the wearing layer of manganese-titanium, there is good wear resistance, this piston ring is not yielding, long service life.
