Abstract
The invention discloses a piston of an automobile air-conditioning compressor, wherein the piston comprises a piston body and a piston rod connection groove arranged on the piston body; a slide surface of the piston body is polished to form a substrate composite layer; an abrasion-resistant lubrication layer is coated outside of the substrate composite layer; and the lubrication layer is a teflon coating layer. The abrasion-resistant coating layer is coated on the sliding surface of the piston body of the piston of the automobile air-conditioning compressor, a piston ring on the traditional piston body is saved by utilizing the properties of high-temperature resistance, low friction coefficient, abrasion resistance and the like of the teflon coating layer are utilized, the structure is simple, the piston is easy to achieve, the cost is low, the service life of the piston is prolonged, and the manufacturing and mounting working procedure is simple.
Description
Technical field
The present invention relates to a kind of automobile air conditioner compressor, relate in particular to a kind of automobile air conditioner compressor piston.
Background technique
Automobile air conditioner compressor is the heart of automobile air conditioning system, plays a part compression and refrigerant conveying steam.Air condition compressor is divided into by inner workings is different: crank-linkage type (by crank, connecting rod, piston, compositions such as air inlet and exhaust valve); Wobble plate type compressor (by main shaft, cone gear, oblique plate, connecting rod, piston, compositions such as inlet and discharge valve and rocker); Oblique tray type compressor (by main shaft, swash plate, cylinder, piston, compositions such as inlet and discharge valve) has these three kinds at present,
Above-mentioned three kinds of compressors are provided with piston, and traditional piston structure such as Fig. 1 and shown in Figure 2 comprise piston only 1 and piston rod connecting groove 5; Offer two annular mounting groove 2 that are used for ring installation 4 on the said piston only 1; Be provided with many protruding straight burrs 3 in the said mounting groove 2, the piston structure of obvious this structure is complicated, processes comparatively loaded down with trivial details; And in the process of ring installation 4; Need carry out the installation of multiple working procedure with many covers tool, piston ring 4 in use easy to wear influences working life of automobile air conditioner compressor piston.
Summary of the invention
To the problems referred to above, the object of the present invention is to provide a kind of automobile air conditioner compressor piston, its have simple in structure, be easy to realize, cost is low and the simple characteristics of installation and processing operation.
The objective of the invention is to realize through following technological scheme:
A kind of automobile air conditioner compressor piston comprises piston only and is opened in the piston rod connecting groove on the piston only, and wherein, polishing forms the substrate composite bed on the slip surface of said piston, and said substrate composite bed scribbles the anti abrasive lubricating layer of one deck outward.
Especially, said lubricating layer is a teflon coatings.
Beneficial effect of the present invention does, said automobile air conditioner compressor piston is coated with anti abrasive lubricating layer on the slip surface of piston only, and is compared with prior art not only simple in structure, be easy to realize; And cost is low, has improved the working life of piston, and the installation and processing operation is simple.
Description of drawings
According to accompanying drawing and embodiment the present invention is done further explain below.
Fig. 1 is the side view of traditional automobile air conditioner compressor piston;
Fig. 2 is the sectional drawing of traditional automobile air conditioner compressor piston.
Fig. 3 is the sectional drawing of automobile air conditioner compressor piston of the present invention.
Embodiment
Please with reference to shown in Figure 3; Fig. 3 is the sectional drawing of automobile air conditioner compressor piston of the present invention; In the present embodiment, a kind of automobile air conditioner compressor piston comprises piston only 1 and is opened in the piston rod connecting groove 5 on the piston only 1 that polishing forms substrate composite bed 6 on the slip surface of said piston only 1; Be coated with the anti abrasive lubricating layer 7 of one deck outside the said substrate composite bed 6, said lubricating layer 7 is a teflon coatings.
Above-mentioned automobile air conditioner compressor piston applies anti abrasive teflon coatings on the slip surface of piston only 1; Utilize teflon coatings high temperature resistant, friction factor is low and characteristic such as wear-resisting; Saved the piston ring on traditional piston only, not only simple in structure, be easy to realize; And cost is low, has improved the working life of piston, and the installation and processing operation is simple.
