<p>A gas turbine engine comprising an annular casing and a bearing housing located concentrically with the casing and in spaced relation thereto. An annular exhaust gas duct is formed between the bearing housing and the outer annular casing. The bearing housing includes a pair of concentric spaced-apart rings connected in a cantilevered manner. The outer ring is supported to the outer casing by annularly, spaced-apart, radially extending support members, and the inner ring includes a cylindrical inner surface to which a concentric bearing support member is tightly fitted therein. The concentric bearing support member includes angularly, spaced-apart, support contact means tightly engaging the inner cylindrical surface of the inner ring while the remainder of the bearing support is out of radial contact with the inner ring of the housing to allow for minimum thermal conduction, yet stressed for relief in the tightly fitting support member within the bearing support housing.</p> |
