Problems solved by technology

However, if the content of solid lubricant increases, the solid lubricant will easily fall off from the lubricating film, resulting in increased wear on the surface of the friction pair and reducing the wear resistance of the sliding parts.
In addition, solid lubricants such as molybdenum disulfide, graphite, and polytetrafluoroethylene have weak bonding forces with metals, and are often used together with binder resins with low melting points, so they are not resistant to high temperatures
These disadvantages also greatly limit their scope of use, so a new lubricating layer must be sought to overcome the above disadvantages

Embodiment Construction

[0021] see figure 2 As shown, the anti-seizing and high wear resistance sliding device 20 provided by the present invention includes a first sliding part 21 and a second sliding part 22 . Wherein there is a layer on the surface of the first sliding member 21 made of a large amount of tungsten disulfide (WS 2 ) The sliding layer 21c formed of a solid lubricant film. Wherein the weight percentage of tungsten disulfide in the solid lubricant film is between 85.0% and 95.0%. Other material components are, for example, 5.0% to 15.0% (weight) of inorganic particles, such as one or a combination of graphite powder, carbon black powder, titanium oxide powder or sulfur powder. The weight content of tungsten disulfide is preferably not less than 90.0%, that is, between 90.0% and 95.0%, and correspondingly, the content of other inorganic particles is between 10.0% and 15.0%. The surface sliding layer 21c has a thickness of 0.2-0.7 μm, preferably 0.5 μm.

Abstract

The invention discloses a sliding device for a compressor, which comprises a first sliding piece and a second sliding piece, wherein at least one sliding piece comprises a surface sliding layer; the surface sliding layer is a solid lubricant film which is formed by means of radio frequency sputtering; and the solid lubricant film contains 85 to 95 weight percent of tungsten disulfide. Therefore, the abrasion resistance and the seizure resistance of the sliding device can be improved.

Description

technical field [0001] The invention relates to a swash plate compressor, in particular to a sliding device of the compressor. Background technique [0002] As shown in Figure 1, in a swash plate compressor, the clutch 1 drives the drive shaft 2 to rotate, and the swash plate 6 and the drive shaft 2 rotate integrally through the drive plate 4 and the hinge mechanism 5 . Each piston 7 is connected with the swash plate 6 through a sliding shoe 8, and the piston 7 reciprocates in the cylinder bore through the rotation or sliding of the swash plate 6. [0003] In this type of compressor, the key point of the sliding condition between the swash plate and the shoes is that when the compressor is just started, the swash plate and the shoes start to slide before the lubricating oil reaches their sliding surfaces, and the refrigeration that arrives earlier The gas has a flushing effect on the lubricating oil remaining on the sliding surface, so before the lubricating oil reaches bet...
