Abstract
A hydrodynamic bearing includes an annular washer having an annular face configured to form a hydrodynamic thrust bearing. The annular face defines a plurality of circumferentially spaced oil grooves having opposing first and second lips extending between inner and outer diameters of the face. The annular face further defines a plurality of circumferentially spaced thrust segments alternating with the grooves such that each of the thrust segments is disposed between an associated pair of first and second ones of the grooves. Each of the thrust segments includes a land that is raised on the face relative to the first and second lips of the associated pair, a first ramp extending from the second lip of the first groove to a first side of the land, and a second ramp extending from the first lip of the second groove to a second side of the land.
