FLUID-SUPPORTED THRUST BEARING

摘要

A thrust bearing allows a first structure to rotate relative to a second structure about an axis of rotation while supporting an axial load between the first structure and the second structure. In an embodiment, the thrust bearing comprises a first annular bearing race slidingly disposed in a first annular recess in the first structure. In addition, the thrust bearing comprises a second annular bearing race engaging the second structure. Further, the thrust bearing comprises a plurality of circumferentially spaced roller elements axially disposed between the first bearing race and the second bearing race. The roller elements contact the first bearing race and the second bearing race. The first bearing race and the first recess define a first annular fluid cavity axially positioned between the first bearing race and the first structure. The first bearing race rides on a fluid disposed in the first fluid cavity.
