Plain Bearing Patents (Class 384/129)
  • Patent number: 10393169
    Abstract: A hydrodynamic plain bearing having a stator and a rotor rotatable with respect to the stator, a rotor bearing surface being located opposite a counter-surface of the stator in order to generate hydrodynamic pressure. The rotor bearing surface and/or the counter-surface constitutes in a section view, in the context of a section along and through the rotation axis, a continuous bearing contour that is constituted from at least two contour segments. The contour segments are suitable for generating hydrodynamic load capacity in a radial and axial direction. The contour segments are led into one another, by at least one transition segment, in such a way that hydrodynamic load capacity is generatable via the contour segments and the transition segment. The plain bearing is embodied as a multiple-surface plain bearing having two or more lubrication wedges in the region of the contour segments and of the transition segment.

  • Patent number: 8967869
    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.

  • Publication number: 20130336607
    Abstract: It is an object of the present invention to provide a sliding bearing which has a simple construction and thus can be produced easily and at a low cost and yet eliminates the need for the use of a heat insulation sleeve and the like and is capable of maintaining a frictional torque to a low extent. A sliding bearing (1) has an inner ring (2), an outer ring (3), and a sliding contact member (4) interposed therebetween. The inner ring (2) has a curved surface (2a) formed along an outer circumference thereof and a shaft-receiving hole which fits on a supporting shaft along an inner circumference thereof. The sliding contact member (4) is a molded body, made of resin composition, which has a curved surface (4a) making sliding contact with the curved outer circumferential surface (2a) of the inner ring (2) with the curved surface (4a) being opposed to the curved outer circumferential surface (2a).
