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. Dowel pins extending radially from the bearing housing and through the engine's interface shell limit the deflection and self-arrest the distortion of the housing. A gas turbine engine includes the retention housing described above.

Abstract: A damper bearing assembly for a gas turbine engine is disclosed. The damper bearing assembly is designed to define forward and aft axial gaps which allow for normal deflection under standard operating thrust loads, but then close during a fan blade out event to allow the increased load to transfer to the damper housing. Frictional forces between contacting parts limit torsional windup and increase torsional resistance with increasing load. The damper bearing assembly includes a damper housing configured substantially within a U-shaped spring finger housing and a spanner nut with a radial hook portion coupled to the spring finger housing. The damper housing is coupled to the spring finger housing such that it is substantially confined within the U-shaped void. The spanner nut is coupled to the spring finger housing such that the radial hook portion is configured to limit the deflection of the spring finger housing and damper housing during a fan blade out event.

Abstract translation: 公开了一种用于燃气涡轮发动机的阻尼器轴承组件。 减震器轴承组件被设计成限定前后轴向间隙，其允许在标准操作推力载荷下的正常偏转，但是在风扇叶片移出事件期间关闭，以允许增加的负载传递到阻尼器壳体。 接触部件之间的摩擦力限制了扭转卷绕，并且随着负载的增加而增加了扭转阻力。 阻尼器轴承组件包括阻尼器壳体，该阻尼器壳体基本上构造在U形弹簧指壳体内，并且扳手螺母具有联接到弹簧指壳体的径向钩部分。 阻尼器壳体联接到弹簧指壳体，使得其基本上限制在U形空隙内。 扳手螺母联接到弹簧指壳体，使得径向钩部分构造成在风扇叶片脱出事件期间限制弹簧指壳体和阻尼器壳体的偏转。
