Abstract:
A sliding film includes a solid lubricant, a binder resin, and a low-melting-point material. The binder resin is for holding the solid lubricant on a surface of a substrate, and exhibits a glass transition temperature. The low-melting-point material exhibits a melting point lower than the glass transition temperature of the binder resin. The low-melting-point material demonstrates a latent heat which can absorb frictional heat generated between sliding members, and accordingly retards the degradation of the binder resin. As a result, the sliding film produces high seizure resistance.
Abstract:
The refrigerating apparatus of the invention has a scroll compressor having a compressing section sucking and compressing a hydrofluorocarbon-based refrigerant, a condenser and the like, in which a plain bearing slidably supporting a driving shaft driving the compressing section of the scroll compressor is made of a material containing lead, and an ether oil miscible with the refrigerant used in a refrigerant circuit is used as a lubricant for lubricating the plain bearing.

Abstract:
A swash plate type compressor is disclosed, wherein a shoe, having a first surface slidably disposed on a swash plate and a second surface received in a pocket formed in a piston, is formed from a copper alloy.
Abstract:
The invention relates to an axial piston engine having an inclined disc (13), sliding blocks (9, 10) provided with bearing sockets (25) and a retaining ring (18), the curved outer face of which is in contact with the inner face of the retaining ring (18). The bearing points (19-21) of the retaining ring (18) are provided with slide-assisting material at least in the contact region to the engine shaft (1).
Abstract:
A single-headed piston type swash-plate-operated refrigerant compressor is provided with a swash plate mounted on a rotatable drive shaft and having front and rear opposite surfaces, single headed pistons arranged on the rear side of the swash plate to reciprocate in respective cylinder bores, and front and rear shoes to be held in slide-contact with the peripheral parts of the front and rear surfaces of the swash plate to engage a tail end part of each of the single headed pistons with the swash plate in which the front and rear surfaces of the swash plate are provided with respective uppermost layers having physical surface properties different from one another. A front uppermost and a rear uppermost layer of the swash plate are formed of a sprayed coating of, for example, a copper-base material and the rear uppermost layer is coated by a solid lubricant layer containing a solid lubricant, such as molybdenum disulfide, at least in a part of the solid lubricant. The thickness of the solid lubricant layer is measured and controlled by using the surface of the front layer as a reference plane.
Abstract:
In order to improve a wear resistance of a copper alloy-sprayed swash plate of a swash plate type compressor, a copper-aluminum composite material consisting of, by spraying, copper or a first copper alloy (e.g., Cu-Pb alloy) containing at least a non-dissolution phase and aluminum or a first aluminum alloy (e.g., Al-Si) containing at least a dissolution phase is sprayed to at least a sliding surface with respect to a shoe.
Abstract:
The invention relates to an axial piston engine comprising an inclined disc (13), sliding shoes (9, 10) with step bearings (25), as well as a lower retainer ring (18) and a ring (16) placed on the motor shaft (1) and having a curved outer surface in contact with the inner surface of the lower retainer ring (18). The bearings (19-21) of the lower retainer ring (18) are provided with a lubricant agent, at least in the contact region with the motor shaft (1).
Abstract:
In order to improve the wear resistance of the swash plate of a swash-plate type compressor, on which plate copper alloy is flame-sprayed, a composite material, which consists of copper or first copper alloy (for example Cu—Pb alloy) including at least unmelted phase and aluminum or first aluminum alloy (for example Al—Si alloy) including at least melted phase, is flame sprayed on the sliding surface with a shoe.
