  • Patent number: 10670074
    Abstract: The present invention provides a method for producing a durable semispherical shoe which can be prevented from being subjected to seizure even in a dry lubrication state in which there is no lubricating oil at a start time of an operation of a swash plate compressor, can be restrained from deteriorating in its lubricating property due to generated frictional heat, and can be restrained from deteriorating in its strength at a production time and an injection molding die. A semispherical shoe (4), for a swash plate compressor, to be produced by the production method has a base material (5), consisting of a hard material, which has a hollow part along a central axis thereof and a resin layer, consisting of a resin composition, which is formed on a surface of a planar part, disposed on a periphery of the base member, which is to be subjected to sliding contact with the swash plate and on a surface of a spherical part, disposed on the periphery thereof, which is to be subjected to sliding contact with a piston.

  • Patent number: 10598167
    Abstract: A swash plate compressor in which a lubricating film is not formed on a sliding contact surface of the swash plate and the piston owing to the use of the semispherical shoe. The semispherical shoe (4) is subjected to sliding contact with the swash plate of the swash plate compressor and the piston thereof. A base material (5) consists of a metallic member having a resin layer (6b) formed on a surface of a planar part (4b) that is subjected to sliding contact with the swash plate. A resin layer (6a) is formed on a surface of a spherical part (4a) to be subjected to sliding contact with the piston. The resin layer (6a) and the resin layer (6b) are integral with each other. At least one portion of the base material (5) is exposed.

  • Publication number: 20170211560
    Abstract: It is an object of the present invention to provide a semispherical shoe which can be prevented from being subjected to seizure even in a dry lubrication state in which there is no lubricating oil at the start time of an operation of a swash plate compressor, is excellent in its sliding contact property and load resistance, does not deteriorate in its lubricating property due to generated frictional heat, does not subject a resin layer to peeling from a base material, and ensures sufficient durability. It is another object of the present invention to provide a swash plate compressor in which a lubricating film is not formed on a sliding contact surface of the swash plate and that of a piston owing to the use of the semispherical shoe. A semispherical shoe (4) is subjected to sliding contact with the swash plate of the swash plate compressor and the piston thereof. Abase material (5) consists of a metallic member.

  • Patent number: 9657728
    Abstract: It is an object of the present invention to provide a semispherical shoe which can be prevented from being subjected to seizure even in a dry lubrication state in which there is no lubricating oil at the start time of an operation, does not deteriorate in its lubricating property owing to frictional heating, and ensures sufficient durability and a swash plate compressor in which a lubricating film is not formed on a sliding contact surface of a swash plate owing to the use of the semispherical shoe. A semispherical shoe (4) makes sliding contact with the swash plate of the swash plate compressor. A surface of a planar part (4b) which makes sliding contact with the swash plate consists of a resin layer (10). A surface of a spherical part (4b) consists of a base material of the semispherical shoe.

  • Publication number: 20150176572
    Abstract: A resin coating-provided swash plate, for a swash plate compressor, manufactured by a process shorter than a process of a conventional coating method and which allows the resin coating to be subjected to grinding processing with high accuracy and to have a high strength of adhesion to a base material of the swash plate, a method for manufacturing the swash plate, and the swash plate compressor having the swash plate. A swash plate (3) for a swash plate compressor is so constructed that inside a housing where a refrigerant is present, a rotational motion of the swash plate (3) mounted perpendicularly and obliquely on a rotational shaft by directly fixing the swash plate (3) thereto or indirectly fixing the swash plate thereto through a coupling member to the rotational shaft is converted into a reciprocating motion of a piston.
