Abstract:
A retention housing for the outer race of a bearing of a gas turbine engine includes a spring finger housing connected to and overlying a bearing housing that is connected to the outer race of the bearing. The spring finger housing includes an arrangement of spring fingers that yields a lightweight housing capable of withstanding very high radial loads combined with very high torsional windup and axial thrust load. A plurality of edge recesses are defined in the bearing housing and a plurality of lug tabs extending radially from the engine's interface shell limit are disposed in the edge recess to limit the deflection and self-arrest the distortion of the retention housing. A gas turbine engine includes the retention housing described above.
