Patent number: 6481895Abstract: A crank shaft thrust bearing half includes a semi-cylindrical bearing shell carrying a pair of radially outwardly projecting thrust flanges having outer thrust surfaces. Radial grooves are formed in the thrust face to divide the surface into thrust pads. Each thrust pad has hydrodynamic contours which provide a hydrodynamic wedging action during rotation of the shaft to support high thrust loads. The thrust pad at the trailing end of the flange has an elevated land area spaced about 30° away from the trailing end and includes a long relief area from the land to the end to provide a no contact zone of the flange. Locating the land away from the trailing end and providing the relief zone shifts the peak pressure location away from the end and toward the middle of the bearing to relieve the trailing end from stress. Having radially oriented oil grooves with suitable width enables adequate oil supply and improved hydrodynamic oil film generating capability.Type: GrantFiled: January 16, 2001Date of Patent: November 19, 2002Assignee: Federal-Mogul World Wide, Inc.Inventors: Qingmin Yang, Robert L.
