Abstract: An improved connecting rod assembly and method for making a connecting rod wherein the installation of the bearing sleeve members in the large bearing end of the connecting rod is improved. The connecting rod is forged, and then notches are cut in the large bearing end to define a separation plane about which the large bearing end is subsequently separated to form a cap member and a body member. Sleeve bearing members are inserted into the cap member and body member. Free ends of the sleeve bearing members project beyond associated surfaces of the cap and body members a predetermined distance. Upon compressive re-attachment of the cap member to the body member, the free ends of the bearing members are compressed and deformed to provide protrusions that extend into the notch. The protrusions help to prevent rotation of the bearing members relative to the bearing housing.

Abstract: 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.
