  • Patent number: 10443654
    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 a resin with a 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 wind power plant having a sliding bearing with a first and second bearing component which are arranged to rotate relative to one another about a common rotational axis is provided. The sliding bearing has at least one sliding lining arranged between the first and second bearing component and has a contact face with a lubricant. The contact face has a sliding lining duct opening to a sliding lining duct, wherein the sliding lining duct crosses the sliding lining and feeds lubricant into a region between the first and second bearing component. The sliding lining has a groove on the contact face, surrounding the sliding lining duct opening. An operation of the wind power plant to generate electric current is also provided. The sliding bearing operates hydrostatically during a startup phase of the rotational movement and/or operates hydrodynamically during a phase of the rotational movement with a constant rotational speed.

  • Patent number: 8888370
    Abstract: A slide bearing for internal combustion engines includes a metal layer having an inner peripheral surface extending along at least a part of a cylindrical shape and a resin coating layer formed on the inner peripheral surface. The inner peripheral surface has annular or helical groove sections extending in a generally circumferential direction of a cylindrical shape such that the inner peripheral surface has protrusion sections, which are arranged adjacent to each other in an axial direction of the cylindrical shape and which extend in the generally circumferential direction. The resin coating layer matches the shapes of the groove sections and the protrusion sections. When t is average coating thickness of the resin coating layer at positions different from crests of the protrusion sections and Rpk is reduced peak height of the resin coating layer, t and Rpk satisfy the following relations: 1.0 ?m?t?5.0 ?m; and 0.06?Rpk/t?5.04.

  • Publication number: 20140307991
    Abstract: The present invention concerns the down hole motors used in the oil prospecting industry to drive drill bits for drilling the ground at great depths. The down hole motor (1) comprises a drive shaft (5) held in the motor body (3) by an axial thrust bearing (6) and by a radial bearing (7). The radial bearing (7) is a tubular member whose interior surface is coated with an anti-abrasion layer (11) formed by laser-assisted facing directly inside an alloy steel radial bearing body (10). The thickness of the facing layer is then reduced by removing material by means of a cutting tool. This produces a radial bearing (7) that is relatively insensitive to drilling mud and confers great reliability on the down hole motor (1).

  • Patent number: 8845195
    Abstract: A bearing element for a sliding bearing is configured to support a drive shaft of a hydraulic machine. The bearing element is connected to the drive shaft so as to prevent relative rotation and has an outer annular surface configured to provide sliding support. A supporting web is formed between a location at which the bearing element is fixed to the drive shaft and the outer annular surface. The supporting web is elastically deformable to compensate for deflection of the drive shaft and/or an alignment error of sliding bearings of the drive shaft. A sliding bearing has a bearing element of this kind, and a hydraulic machine has at least one sliding bearing of this kind.
