Provided is a sliding member, method for manufacturing sliding member, and compressor swash plate using sliding member in which adhesion between the substrate and the resin is enhanced, and which has the excellent durability whereby peeling of the resin film from the substrate does not occur due to prolonged sliding even under harsh load conditions. The sliding member provides a substrate irradiated laser light with energy intensity per unit area of 0.053 J/mm2 or more and configured an uneven part formed toward a vertical direction by the irradiated laser light and a melted and solidified portion on the uneven part and a resin film including solid lubricant and a binder resin on the substrate.

A swash plate type compressor is arranged with a plurality of semispherical shoes and a disc shaped swash plate. A resin coating is formed on a surface and a rear surface (sliding surface) of the swash plate which slides with the shoe. The resin coating includes a structure whereby multiple hexagonal cylinder bodies are fabricated on a surface of a substrate and an end surface of each cylinder body forms a sliding surface which slides with the shoe. In addition, a honeycomb shaped groove is formed at an adjacent position of each cylinder body forming a storage part of a lubricant O and a container part for foreign objects.The swash plate can be provided with excellent wear resistance, seizure resistance and lubrication retention.

A hemispherical shoe (sliding member) 1 has a flat sliding surface 3, which is quenched to form a quenched portion 7. A part of the quenched sliding surface is partially annealed to form an annealed portion 6. When an oil film pressure acts on the sliding surface 1, the annealed portion 6 is deformed by pressure so that the surface thereof has a concave portion 6A. In the annealed portion 6, a remaining quenched portion 8 may remain at the center part thereof. The concave portion 6A can be used as an oil reservoir or an oil flow path, so that an excellent seizure resistance can be ensured.

A sliding member for a compressor includes a base metal, a first layer and a second layer. The base metal is made of an aluminum-based metal. The first layer is formed on or over the base metal and made of a nickel-based plating layer containing at least one material of nitrogen (N), silicon (Si), titanium (Ti), chromium (Cr) and aluminum (Al) as an additive. The second layer is formed on the surface of the first layer and made of a diamond-like carbon layer containing the same additive as the additive contained in the first layer.

A shoe 5 includes a spherical portion 5A in sliding contact with a sliding surface 4a that is a hemispherical concave portion of a piston 4, an end surface portion 5B in sliding contact with a swash plate 3, and a circular cylindrical portion 5C formed between the spherical portion 5A and the end surface portion 5B. A plurality of linear oil grooves 5F are formed in the outer peripheral surface of the cylindrical portion 5C.A lubricant oil separated from a refrigerant is held in each of the oil grooves 5F of the cylindrical portion 5C of the shoe 5 when a swash plate compressor 1 is in a non-operating state. When the swash plate compressor 1 is started, the lubricant oil in the oil grooves 5F is fed to the spherical portion 5A and the end surface portion 5B which are sliding portions.The shoe 5 having excellent lubricity in comparison with a conventional case can be thereby provided.
摘要:
There is provided a semispherical shoe which is formed into a substantially semispherical shape by a convex semispherical surface 2 and a flat end surface 3, the semispherical surface having a slidably contacting surface 6 that is in slidable contact with a semispherical concave portion and non slidably contacting surfaces 7 and 8 that are not in slidable contact with the concave portion. When the semispherical shoe is manufactured, first, after a semispherical material having a semispherical surface following the concave portion has been formed, the surface of the portion that is to be the slidably contacting surface on the semispherical surface is quenched to expand the quenched portion from the original surface of the semispherical surface, whereby the sliding surface is formed on the surface of the expanded portion, and the other portions are made the non slidably contacting portions.
摘要:
An axial piston motor, particularly an air-conditioning compressor for motor vehicles, including at least one piston with an essentially cylindrical piston skirt and with a wrap-around element, which wraps around a swivel ring or a swash plate and a piston slipper that slides on this swivel ring or this swash plate.
