Abstract
A dual wedge thrust bearing for holding two relative rotating members in spaced relation includes a wave spring which supports both a thick flexible plate and a thin flexible plate stacked in that order between the cooperating bearing surfaces of the members. By securing the leading edge of the thin plate to the member on which the wave spring rests and in spaced relation to the cooperating bearing surface, a wedge-shaped passage is formed to create a fluid bearing which is efficient for low speeds and loads. At high speeds and loads, when the thin plate would have sagged making an inefficient wedge, the thick plate deflects against the spring at its leading edge to form a more efficient wedge-shaped opening between it and the cooperating bearing surface.
