Problems solved by technology

[0003] In the above-mentioned swash plate compressor, since the lubricating oil contained in the refrigerant at the initial stage of operation reaches the sliding part of the swash plate that is in contact with the shoe, the swash plate and the shoe slide, so the above-mentioned sliding part is in an unlubricated state. The dry lubricating state of the oil is prone to melting

Embodiment

[0035] In order to study the influence of the average aspect ratio and the average particle diameter of the fluororesin particles in the binder resin on the melting resistance, the following tests were conducted. The coating material for sliding of the example was prepared by stirring and mixing the film-forming component of the blend composition described in Table 1 and an appropriate amount of organic solvent (N-methylpyrrolidone) with a screw mixer. On the other hand, the coating material for sliding of Comparative Example was prepared by pulverizing and mixing the film-forming component of the blend composition described in Table 1 and an appropriate amount of organic solvent (N-methylpyrrolidone) with a sand mill. On the other hand, after degreasing the swash plate base material made of iron and steel, the surface was roughened by shot blasting so that the surface roughness was 9.0 μmRzjis. The coating material for sliding was coated on the surface of the swash plate subs...

Abstract

[Problem] To dramatically improve the swash plate seizure resistance of a swash plate compressor in comparison to the prior art by optimizing the average aspect ratio and the average particle diameter of fluorine resin particles present in the sliding film of the swash plate of a swash plate compressor. [Solution] The swash plate of a swash plate compressor, wherein the sliding section of the swash plate which slides with a shoe is provided with a sliding film formed from a binder resin, fluorine resin particles having an average aspect ratio of 1-1.5 and an average particle diameter of 7-13μm, and graphite.

Description

technical field [0001] The present invention relates to a swash plate type compressor used in vehicle air conditioners and the like. Background technique [0002] Among the swash plate compressors, there are fixed capacity swash plate compressors and variable capacity swash plate compressors in which the swash plate is directly fixed to the drive shaft with the slant The above-mentioned variable capacity swash plate compressor is installed in the casing in a rotatable manner. The swash plate is installed on the drive shaft in a slidable manner with a variable inclination angle through a connecting member. No matter what kind of compressor is used, the sliding The shoe slides on the swash plate, and the sliding shoe converts the rotary motion of the swash plate into the reciprocating motion of the piston to compress the refrigerant. [0003] In the above-mentioned swash plate compressor, since the lubricating oil contained in the refrigerant at the initial stage of operation...
