Swash plate of swash plate compressor and swash plate compressor

Abstract

Provided are a swash plate of a swash plate compressor which has excellent seize resistance under extreme pressure conditions due to one-side hitting of a shoe in sliding contact with the swash plate or in such a condition that lubricant oil runs out and is capable of preventing erosion of a coating due to cavitation at high surface pressure and high speed under existence of the lubricant oil, and a swash plate compressor comprising the swash plate. The swash plate is a swash plate 3 of a swash plate compressor wherein shoes 4 slide with respect to the swash plate 3 orthogonally and obliquely mounted so as to be fixed to a rotating shaft 2 directly or indirectly via a connection member in a housing 1 where a refrigerant exists, rotational motion of the swash plate 3 is converted to reciprocating motion of a piston 5 via the shoes 4, and the refrigerant is compressed and expanded. Resin coatings are formed on sliding surfaces on which the shoes 4 slide. Each resin coating includes 25 to 70 parts by weight of fluororesin and 1 to 20 parts by weight of graphite with respect to 100 parts by weight of matrix resin, and has the tensile shear adhesive strength of at least 25 MPa.

Description

technical field

[0001] The present invention relates to a swash plate and a swash plate compressor used for a swash plate compressor of an air conditioner or the like. Background technique

[0002] In the case of a swash plate compressor, in the case where the refrigerant exists, a swash plate installed directly at a right angle and obliquely through a connecting member in a manner directly fixed to a rotating shaft slides a sliding foot through which the swash plate The rotary motion of the piston is transformed into the reciprocating motion of the piston, which compresses and expands the refrigerant. Among such swash plate compressors, there are double swash plate type that compresses and expands refrigerant on both sides using a double-headed piston, and single swash plate type that uses a single-headed piston to compress and expand refrigerant on only one side. . In addition, the slider includes a slider that slides only on one side of the swash plate and a slider that...
