Benefits of technology
The present invention relates to a swash plate type compressor that improves adhesion resistance of the swash plate. The compressor includes a drive shaft, swash plate, shoe, and piston. A lubrication film made of a cured coating film composed of a binder resin containing polyamideimide resin and bisphenol-A epoxy resin and a solid lubricant containing polytetrafluoroethylene and graphite is provided on the surface of the swash plate substrate. The technical effect of the invention is to provide a more efficient and reliable swash plate type compressor that can better withstand high temperatures and pressures, leading to improved performance and reliability.
Problems solved by technology
However, the methods including formation of an intermediate layer disclosed in Patent Documents 1 and 2 has a drawback of increased manufacturing cost results from the intermediate layer.
However, these methods are not sufficient to achieve a strict adhesion resistance required in further developed swash plate type compressor, and further improvement in adhesion resistance is required.

[0025]Following examinations were carried out to investigate the influence of the content of bisphenol-A epoxy resin in the binder resin on the adhesion resistance. The lubricous coating paint having compositions shown in Table 1 were prepared as the composition for film formation. Further, the swash plate substrates made of steel were subjected to the degreasing treatment, followed by shot blasting for roughening the surface and adjust the surface roughness in Rzjis to be 9.0 micron-meters. The lubricous coating paints were applied on the surface of the swash plate substrates to make the dried film thickness of 60 micron-meters followed by by heating at 230° C. for 30 minutes for curing. Then, the cured coating films were ground by a grinder to smoothen the surface to finish a lubrication films having surface roughness in Ra of 0.8 micron-meters. The average particle size of a used PTFE particle was 10 micron-meters, and the average particle size of graphite was 4 to 5 micron-meter...

Abstract
[Problem to be Solved]To improve the adhesion resistance of a swash plate in a swash plate type compressor.[Means to Solve the Problem]Lubrication film made of a cured coating film composed of a binder resin containing 100% by weight of polyamideimide resin and 2 to 18% by weight of bisphenol-A epoxy resin, and a solid lubricant containing polytetrafluoroethylene and graphite is provided on the surface of the swash plate substrate.
Description
TECHNICAL FIELD[0001]The present invention relates to a swash plate type compressor used in an air conditioner for vehicle.BACKGROUND ART[0002]The swash plate type compressor includes a fixed capacity swash plate type compressor in which a swash plate is directly fixed to a drive shaft rotatably disposed in a housing with tilt, and a variable capacity swash plate type compressor in which a swash plate is attached to the drive shaft through a connecting member to make tilt angle variable and slidable. In both of the swash plate type compressors, the swash plate slide on a shoe and a rotation of the swash plate is converted into a reciprocal movement of a piston through the shoe to compress and expand a refrigerant.[0003]In the swash plate type compressors, as the swash plate slides along the shoe in an early stage of the operation before a lubricant contained in the refrigerant reaches the sliding portion, the sliding portion is made dry lubrication state without lubricant, and adhes...
