  • Publication number: 20170276175
    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.
