Description
Technical field
This utility model relates to a kind of piston structure, the piston structure in a kind of cylinder in automobile air conditioner compressor specifically.
Background technology
Automobile air conditioner compressor is the heart of automobile air conditioning refrigerating system, play a part compression and conveying cold-producing medium, oblique disk structure automobile air conditioner compressor is again the mainstream model of existing market, its feature such as compact conformation, long service life, is mainly used in Light-duty Vehicle, passenger car and medium and high classes car.Power is reached swash plate by driving axle by automobile air conditioner compressor, power is transferred to piston by hemisphere by swash plate, the convert rotational motion of electromotor is become the reciprocating motion of piston, so the piston in cylinder in automobile air conditioner compressor is belonging to directly participate in the part of acting, play very important effect.
Now with user's improving constantly air conditioning for automobiles performance, assembly plant also improves constantly in the performance constantly requiring automobile air conditioner compressor, so not improving cost, the rotating speed improving automobile air conditioner compressor when using with a type has become to put forward high performance first-selection, and the raising of automobile air conditioner compressor rotating speed must make piston operation frequency higher, now just require that piston has better performance.Find after at present market fault part compressor being disassembled analysis that subject matter is, owing to Design of Piston Structure is unreasonable, frictional force is big, the Impact direction of piston is inconsistent with piston axis, makes piston lateral surface inordinate wear serious on the one hand, is substantially reduced the service life of itself, make piston stress asymmetric on the other hand, cause that part is in one side abrasion, finally results in complete machine and lost efficacy, thus causing bigger economic loss.
Utility model content
For the problems referred to above, the problem that this utility model intends to solve be to provide a kind of simple and reasonable, stress symmetrically and evenly, wearability is good and piston structure in the cylinder in automobile air conditioner compressor of long service life, it is effectively improved the service life of whole automobile air conditioner compressor, reduces economic loss.
For reaching above-mentioned purpose, this utility model is by the following technical solutions: the piston structure in a kind of cylinder in automobile air conditioner compressor, including piston only, on the lateral surface of described piston only two ends, symmetry is provided with twice circular oil groove, described piston only centre position is provided with one and opens shelves, described piston only opens that shelves are monosymmetric is provided with two ball-and-sockets described in being internally located at, axiality between axis and the axis of described piston only of two described ball-and-sockets is 0～0.02mm, the sphere diameter of each described ball-and-socket is 14.323～14.345mm, the surface roughness of each described ball-and-socket and the surface roughness of described piston only lateral surface are Ra0.4.
As preferably, the axiality between axis and the axis of described piston only of two described ball-and-sockets is 0mm.
As preferably, the sphere diameter of each described ball-and-socket is 14.334mm.
As preferably, the lateral surface of described piston only being coated with a polytetrafluoroethylene floor equably.
Effective achievement of the present utility model: this utility model is simple and reasonable, its ball-and-socket position, size design have been carried out, and the axiality between axis and the axis of piston only of two ball-and-sockets is accurate to 0～0.02mm, guarantee when power is reached piston by hemisphere by swash plate, the Impact direction of piston is consistent with the axis of piston, the frictional force making piston lateral surface and cylinder holes keeps symmetrically and evenly, avoid the occurrence of the part phenomenon in one side abrasion to occur, thus being effectively improved the service life of whole automobile air conditioner compressor, reduce economic loss；On the lateral surface of piston only two ends, symmetry is provided with twice circular oil groove, the surface roughness of the surface roughness of each ball-and-socket and piston only lateral surface is all set to Ra0.4, and on the lateral surface of piston only, it is coated with a polytetrafluoroethylene floor equably, it is substantially reduced the frictional force of piston lateral surface, improve wearability, increase the service life.
In sum, this utility model have simple and reasonable, stress symmetrically and evenly, wearability is good and the feature of long service life, be effectively improved the service life of whole automobile air conditioner compressor, reduce economic loss.
