Inter-rotor bearing assembly

摘要

An inter-rotor bearing assembly includes a first annular member having a circumferential inner surface and a second annular member having a circumferential outer surface. The outer surface is concentric to and disposed radially inward of the inner surface and a bearing is disposed between the surfaces. The bearing has an outer race fixedly attached to the first annular member along the inner surface, an inner race fixedly attached to the second annular member along the outer surface, and rolling elements disposed between the races. A low density high circumferential strength support ring is fixedly attached to the first annular member disposed concentrically outside of the inner race and is preferably made of a titanium matrix composite. The rolling elements may be cylindrical rollers having cylindrical rolling surfaces. The support ring may be fixedly attached around or integral with the first annular member.
