摘要
A split crankshaft bearing assembly includes two flanged half bearings adapted to collectively encircle a crankshaft. The flanges are formed with oil supply grooves that subdivide the flange surface into thrust bearing pads. Each pad includes a positively sloped ramp surface leading to a raised land surface. The rotating crankshaft drags a film of oil onto the land surface where it provides hydrodynamic thrust support for the shaft. To facilitate close tolerance control on the thrust bearing pad contour, the manufacturing process is carried out so that the oil supply grooves are formed and the thrust face presized prior to formation of the pad final contour. The pad contour is formed by a coining operation.
