Abstract:
A bearing for a hinge in a hinged raked aircraft wing tip includes an outer member that has a concave inner surface and an inner member that has first and second inner segments. Each of the first and second inner segments has a base that has a bearing section extending therefrom. The bearing sections together form a convex outer surface that is complementary in shape to the concave inner surface. A preload feature is positioned between and engages a portion of the bearing sections. A lubricous liner is positioned between the concave inner surface and the convex outer surface. The bearing sections are positioned in the outer member to compress the preload feature to limit axial movement between the outer and inner members to a predetermined magnitude. The preload feature flexes outward as a result of wear to the liner to maintain the axial movement to the predetermined magnitude.
Abstract:
A seal-bearing assembly to be inserted into the seal cavity of a mechanical device to provide a seal and a bearing surface to eliminate whip in a rotating, reciprocal, or rotating and reciprocal cylindrical member. The seal-bearing assembly is particularly well suited for use in a reciprocal pump or a piston-driven valve, or between the steam lance and fixed steam tube in a sootblower. The assembly includes at least a pair of outer substantially rigid cylindrical bearings having an inner bore to be positioned over the cylindrical member and at least one complimentary flexible textile packing ring substantially comprised of carbon disposed between the two outer bearing members. In assemblies including an additional bearing, the additional bearing is surrounded by at least one flexible packing on each side. The inner bore of the bearing members provides a bearing surface for eliminating whip of the moving elements in the device.
Abstract:
Bearing 11 has base material 110 and coating layer 111. Base material 110 contains crank shaft 13 on an inner circumferential surface side. The inner circumferential surface of base material 110 is coated with coating layer 111. The inner circumferential surface side of base material 110 is coated with resin with thickness t, the resin is dried, and thereafter surface treatment is carried out such that multiple grooves C are provided on the surface of the resin so as to intersect with the direction of crank shaft 13, whereby coating layer 111 is formed. Peak portions B formed between adjacent grooves C come into contact with the outer circumferential surface of crank shaft 13 to support crank shaft 13. With bearing 11, the thickness of peak portions B at the center in the direction of the crank shaft 13 differs from the thickness of peak portions B at the end.
Abstract:
A generator includes a sliding member, a first power generation element and a second power generation element. The sliding member is made of a biomass-containing material. The first power generation element is configured to slide with respect to the sliding member. The second power generation element is configured to generate electrical power by variation of its relative position with respect to the first power generation element.
Abstract:
A self-lubricated bearing contains a first member, a second member configured to slide against the first member, and a lubricating liner disposed in a sliding contact area between the first member and the second member. The lubricating liner contains at least one structural polymer and at least one lubricant with viscosity less than 5100 centistokes. A method is also provided for making the bearings, which includes adding the at least one lubricant with viscosity less than about 5100 centistokes to one or more components of the lubricating liner during the process of making the liner or bearing. The self-lubricated bearing compositions of the invention have surprisingly long service lives versus prior art self-lubricated bearings.
Abstract:
A curved sliding unit has stable sliding performance and long service life. The curved sliding liner in a bowl shape obtained by rolling a ribbon-shaped woven cloth forms steps in the width direction of the ribbon. A curved sliding unit includes an external member, the curved sliding liner disposed inside the external member, and an internal member disposed inside the curved sliding liner.
Abstract:
A low-friction sliding material includes a sliding member having a sliding surface, and a fluorine fiber or a fluorine fiber-containing composite fiber disposed in parallel at least on the outermost part of the sliding surface in a direction substantially the same as a sliding direction and covers 60% or more of the sliding surface. A low-friction sliding material is free from the occurrence of fabric separation or other defects in an extremely easy manner.
Abstract:
In a method of manufacturing a sliding member including a polyamide resin and a filler, a compound having a carbodiimide bond is supplied during kneading of the polyamide resin and the filler.
Abstract:
A sliding engine component may include a sliding surface including a plastic polymer-based layer disposed on a metallic substrate. The plastics polymer-based layer may include a plurality of plastic polymer-based layers. The plurality of plastic polymer-based layers may include a first coating of a first polymer-based layer deposited on the metallic substrate and cured at a first temperature, and a second coating of a second polymer-based layer deposited onto the first polymer-based layer and cured at a second temperature. The second temperature may be lower than the first temperature.
Abstract:
A sliding member includes: a metal substrate; an undercoat primer layer that is formed on a sliding surface of the metal substrate; and a resin layer that is formed on the undercoat primer layer, in which the resin layer is formed by curing a composition layer containing a bifunctional alicyclic epoxy and a polymerization initiator.
