    摘要: A dry rolling element bearing assembly for rotatably mounting a flight vehicle engine shaft to a housing. Rolling elements (such as ball bearings) are positioned between inner and outer races. Stop devices axial position the inner and outer races. A mounting device positions the inner race radially outward from the shaft so as to create a first annular air space between them. The mount has a flexible portion and has a support ring portion which contacts the outer surface of the inner race with a radial interference fit. A similar mounting device positions the outer race radially inward from the housing. Air directing devices direct cooling air impingingly against bearing surfaces.
