    Abstract: A bushing assembly includes a tube with an outer bearing surface, a metal part with an annular flange defining an opening and a plastic bushing with a bushing hub with an inner annular bushing contact surface and an axially extending metal part engagement surface. A friction torque setting connection is formed between the annular flange and the bushing hub and defines a rotational and axial connection between the annular flange and the bushing hub. The connection is configured to vary a radial force applied between the annular flange and the bushing hub with a deformation of bushing plastic material. This is to vary friction between the bushing contact surface and the tube outer bearing surface upon applying a torque to the plastic bushing, causing rotation and axial movement of the plastic bushing relative to the metal part, and causing the deformation of plastic material of the bushing hub.

    Abstract: Particles, embedded into a sliding layer, have a coating, within which a lubricant, e.g., a liquid, is contained. A component with the sliding layer provides a sliding surface that can be used as a backup bearing to ensure emergency operating properties, for example, of a shaft that is mounted in a main bearing. When the shaft strikes the bearing surface, the coating of the particles that are exposed on the bearing surface are destroyed and the lubricant can exit. Advantageously, the sliding properties of the sliding surface are thereby improved.

  • Patent number: 8529319
    Abstract: Embodiments of the present invention resolve the safety and product management issues associated with conventional abrasive wheel bushings by, for example, reducing the opportunity for improperly mounting an abrasive wheel without the appropriate reducing bushing, simplifying the purchasing process, and/or reserving valuable SKU space for primary products. The abrasive wheel itself can be tailored to any number of purposes, such as grinding, cutting, and polishing. The bushing described herein can be used with any such abrasive wheels. The techniques could readily be extended to any arbor-based products that use reduction bushings or similar schemes.

  • Patent number: 8371755
    Abstract: A sleeve bearing device is disclosed for supporting a worm gear journal disposed within a casing of a valve actuator. The device includes a ring shaped portion having an inboard and an outboard end. The outboard end of the ring shaped portion defines a radially outwardly extending flange which cooperates with the casing for inhibiting axial movement of the ring shaped portion relative to the casing. The ring shaped portion is of cylindrical configuration and defines an inner and an outer surface. The inner surface of the ring shaped portion bearingly supports the worm gear journal. The outer surface of the ring shaped portion cooperates with the casing, the casing defining an annular groove. The annular groove is disposed coaxially relative to the ring shaped portion, the annular groove being located adjacent to the outer surface of the ring shaped portion and between the inboard and the outboard ends of the ring shaped portion.

  • Patent number: 8205515
    Abstract: A bushing for use in a hollow tube housing of a rack and pinion steering system. The bushing is formed as a generally cylindrical body having a central aperture and a circular cantilevered flange that extends outward from the body of the bushing. The flange contains a leading surface for compression contact with a corresponding interfering surface on the hollow interior of the rack housing. The flange is disposed to continuously compress a portion of its leading surface against a portion of the interfering surface on the hollow interior of the housing over a predetermined range of temperatures when the bushing is installed in the housing, and thereby providing thermal compensation to maintain a seal.
