Abstract
The utility model discloses a piston assembly, comprising a steel bushing, a piston, a piston ring, etc. The utility model is characterized as follows: the inner wall of the steel bushing is added with a layer of boron carbide steel bushing internal layer; the external wall of the piston is added with a layer of boron carbide piston external layer; the outer surface of the piston ring is added with a layer of boron carbide piston ring external layer. The utility model overcomes problems of bad direct contact abradability of the steel bushing, the piston and the piston ring and low service life. The utility model adapts to various engine mounting.
Description
Technical field
The utility model relates to the dynamic power machine field, specifically a kind of piston apparatus of mechanical engine.
Background technique
At present, society generally uses the mechanical engine piston, all directly contact with steel bushing, piston and piston ring, its shortcoming be not wear-resisting, use the longevity low.
Summary of the invention
The utility model wears no resistance, uses low problem of longevity for solving the direct contact of steel bushing, piston and piston ring, and a kind of piston assembly that has scuff-resistant coating is provided.
The utility model is to solve the problems of the technologies described above the technological scheme that is adopted to be, a kind of piston assembly, constitute by steel bushing, piston and piston ring etc., its special way is: be added with one deck boron carbide steel bushing internal layer on the inwall of steel bushing, on the outer wall of piston, be added with one deck boron carbide piston skin, be added with one deck boron carbide piston ring skin at the outer surface of piston ring.When pistons work, the friction between steel bushing, piston and the piston ring is carried out on its top layer like this, utilized wear resistance protection steel bushing, piston and the piston ring of boron carbide.
Technique effect of the present utility model is, adopts above-mentioned technological scheme, can realize a kind of engine piston assembly of long service life.
Description of drawings
Fig. 1 is a structural front view of the present utility model, and the accompanying drawing that makes an abstract.
In the drawings, 1 steel bushing, 2 steel bushing internal layers, 3 piston skins, 4 pistons, 5 piston ring skins, 6 piston rings
Embodiment
Below in conjunction with accompanying drawing embodiment, the utility model is further specified.
As shown in the figure, piston assembly is made of steel bushing 1, piston 4 and piston ring 6 etc., is added with one deck boron carbide steel bushing internal layer 2 on the inwall of steel bushing 1, on the outer wall of piston 3, be added with one deck boron carbide piston skin 3, be added with one deck boron carbide piston ring skin 5 at the outer surface of piston ring 6.When pistons work, the friction between steel bushing 1, piston 4 and the piston ring 6 is carried out on its top layer like this, utilized wear resistance protection steel bushing 1, piston 4 and the piston ring 6 of boron carbide.
