  • Patent number: 10753401
    Abstract: A method for producing a roller bearing may include threading a cam roller onto a bearing sleeve until the cam roller abuts a first axial flange of the bearing sleeve and inserting a counter holder into the bearing sleeve until the first axial flange of the bearing sleeve abuts a stop of the counter holder. The method may also include heating the bearing sleeve and forming an opposite second axial flange via inserting a forming punch into the bearing sleeve after heating the bearing sleeve. The second axial flange may be formed such that the cam roller is held in the bearing sleeve with radial play and axial play after the bearing sleeve cools down. The method may further include removing the forming punch and the counter holder from within the bearing sleeve.

  • Patent number: 8956049
    Abstract: A method for producing a fracture-divided component, in particular a connecting rod, with an at least partially coated bore includes the steps of: providing an unfinished component; applying a coating of a bearing material to a bore surface; and working the coating, in order to compensate internal tensile stresses in the coating, before fracture division of the component. Alternatively, the method for producing a fracture-divided component, in particular a connecting rod, having an at least partially coated bore includes the steps of: providing an unfinished component; applying a coating of a bearing material to a bore surface before fracture division of the component; and forming a counter-hardness zone before the application of the coating in order to generate compressive stresses which oppose the internal tensile stresses of the coating.

  • Publication number: 20150041575
    Abstract: A gyratory crusher bearing includes a bearing surface to support rotational movement of a crushing head, wherein a shape profile of the bearing surface at a cross section of the bearing perpendicular to a longitudinal axis of the bearing is substantially circular. A mounting surface is positioned against a bearing support and is orientated to be outward facing relative to the longitudinal axis. A bearing wall is defined between the mounting surface and the bearing surface, the bearing surface defining a central bore extending between a first edge end and a second edge end of the wall. At least one region of the mounting surface in combination with the bearing surface defines the wall between the first edge end and the second edge end and includes a shape profile at a cross section of the bearing perpendicular to the longitudinal axis that is non-circular to define an anchorage region to inhibit rotation of the bearing about the longitudinal axis relative to the bearing support.

  • Publication number: 20130315517
    Abstract: Enhanced abrasion resistance in well fluid wetted assemblies is described. The bearing set of the invention provides an enhanced abrasion resistance that is better capable of withstanding friction from solids in electric submersible pump (ESP) well production applications. The flutes, grooves, sectors and intersections of the invention provide improved fluid and solid flow through assembly components, which improves cooling while the assembly is in operation and reduces body wear, thereby increasing the lifespan of the ESP system.

  • Patent number: 6902323
    Abstract: A locking device and its assemblage are provided for confining an object such as a shaft of a motor. The locking device is used to confine the shaft having an end with a recess portion having a defining surface to prevent the shaft from being displaced in an axial direction. The locking device is a geometrically closed-loop body having an opening, and having a flexibility so that the shaft will pass through the opening and the end of the shaft will thus be confined by the locking device while the force disappears. The locking device is free from contact with the recess portion of the shaft when the shaft is spinning. A simple process can be used to assemble and disassemble the locking assemblage.
