  • Patent number: 10760614
    Abstract: In a bearing device, a squeeze film damper includes an annular oil chamber forming an oil film between an outer periphery of an outer race and an inner periphery of a bearing retaining member. A film thickness adjustment portion adjusting a film thickness of the oil film is provided in at least one location in a peripheral direction of the oil chamber. Therefore, it is possible, by changing a distribution in a peripheral direction of dynamic characteristics of the oil film of the squeeze film damper with a simple structure to thus freely adjust a forward mode tendency or a backward mode tendency for centrifugal whirling, to enhance damping performance of the squeeze film damper. Accordingly, centrifugal whirling of a rotating shaft is suppressed effectively by the squeeze film damper with a simple structure.

    Abstract: A cylinder assembly includes a housing defining first and second outer cylindrical surfaces having a longitudinal axis and a shim having a retaining ring fitted over the first outer cylindrical surface. The shim includes a plurality of connector spokes extending from the retaining ring, and a corresponding plurality of shim elements configured at the ends of the plurality of connector spokes. The connector spokes extend radially from the retaining ring relative to the longitudinal axis when the shim is in a pre-installation configuration. The connector spokes are bendable such that the shim elements extend longitudinally and are positioned next to the second outer cylindrical surface when the shim is in an installation configuration. Shims, methods of assembly, bicycles and other components are also provided.

  • 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.

  • Patent number: 8734130
    Abstract: An exemplary anisotropic member supports a semi-floating bearing in a bore and can reduce non-synchronous vibration of the bearing in the bore. An anisotropic member can include an annular body configured to receive a semi-floating bearing and to space the bearing a distance from a bore surface and can be configured to impart anisotropic stiffness and damping terms to the semi-floating bearing when positioned in the bore. Such a member is suitable for use in a rotating assembly for a turbocharger where the bearing may be a semi-floating bearing. Various exemplary members, bearings, housings, assemblies, etc., are disclosed.
