    Abstract: A fan drive gear system for a gas turbine engine includes a carrier supporting circumferentially arranged gears within gear mount sections spaced circumferentially about a periphery. A shelf is disposed between each of the gear mounting sections. A torque frame is attached to the carrier and includes circumferentially arranged finger sections. Each of the finger sections includes first and second ends that are spaced apart to receive the shelf. A pin extends through openings in the shelf and first and second ends to secure the torque frame to the carrier.

    Abstract: A method for assembling a turbofan engine (20) comprises coupling a bearing assembly (176) and a shaft (420) as a unit to a bearing support (453). A transmission (46) and the fan shaft (132) are installed to a front frame assembly (172). The bearing assembly and shaft are installed as a unit so that the shaft engages a central gear (52) of the transmission and the bearing support engages the front frame assembly.

    Abstract translation: 一种用于组装涡轮风扇发动机（20）的方法包括将轴承组件（176）和作为单元的轴（420）联接到轴承支撑件（453）。 变速器（46）和风扇轴（132）安装到前框架组件（172）上。 轴承组件和轴被安装为单元，使得轴接合变速器的中心齿轮（52）并且轴承支撑件接合前框架组件。

    Abstract: A support assembly for a geared architecture includes an engine static structure. A flex support is secured to the engine static structure and includes a bellow. A support structure is operatively secured to the flex support. A geared architecture is mounted to the support structure. First members are removably secured to one of the engine static structure and the flex support and second members are removably secured to the support structure. The first and second members are circumferentially aligned with one another and spaced apart from one another during a normal operating condition. The first and second members are configured to be engageable with one another during an extreme event to limit axial movement of the geared architecture relative to the engine static structure.
