    摘要: A turbocharger 51 is provided with an improved bearing 52, preferably formed as a semi-floating ring journal bearing which has hydrodynamic flexure pivot tilting pads 53 on the inner diameter thereof and compliant structural dampers 54 on the outer diameter thereof. The compliant structural dampers 54 are installed between an outer bearing surface and an inner surface of a bearing chamber 56. These compliant structural dampers 54 can be formed as metal mesh dampers 71 or bump foil dampers 72 which are effective to dissipate mechanical energy from structural damping and dry-friction.

    摘要: Coast-down bearing apparatus and methods are provided. The coast-down bearing includes a plurality of segments each having a radius of curvature substantially equal to an outer radius of a shaft and spaced radially therefrom to define a clearance, with the plurality of segments being configured to receive the shaft when a magnetic bearing drops the shaft. The coast-down bearing also includes a plurality of slots disposed between adjacent ones of the plurality of segments.

    摘要: A cast element comprises an elongated cast body having an axial opening in a direction of its axis thereof, and first and second friction bearings at ends of the axial opening. The friction bearings are formed as a single piece with the cast body, and each friction bearing consists of several slide elements with a space between them. Each of the slide elements has a cross section shaped like a cylindrical ring segment, and the slide elements of the first bearing are circumferentially alternate with the slide elements of the second bearing.

    摘要: A fluid-dampened support for a bearing such as a tilt pad bearing or a rolling element bearing such as a ball bearing, needle bearing, roller bearing and the like. The fluid dampened support includes a network of closely spaced beams which act as structural springs which support the outer race of the roller bearing for movement in any direction. The spring rate or constant of these structural springs can be caused to change after a selected amount of deflection. The amount of deflection needed to cause the change in spring rate can be adjusted to suit the particular application. A liquid is provided in the spaces between the beams to dampen movement of the pads. The damping rate can be made to change with movement of the pads. The structure and space between the beams is designed so as to provide virtually any reasonable damping characteristics. By providing such damping characteristics, the bearings are able to limit or damp out the vibrations occurring when the supported member passes through natural frequencies before reaching operating speed. This allows use of the rolling element bearing in high speed equipment such as compressors and turbines.
