Embodiment Construction

[0013] FIG. 1 is a schematic diagram of a gas turbine engine 10 including a blower assembly 12 , a high pressure compressor 14 , and a combustor 16 . Engine 10 also includes a high pressure turbine 18 , a low pressure turbine 20 , and a supercharger 22 . The fan assembly 12 includes a set of fan blades 24 extending radially outward from a rotor disk 26 . Engine 10 has an intake side 28 and an exhaust side 30 .

[0014] In operation, air flow passes through the blower assembly 12 and the compressed air is supplied to a high pressure compressor 14 . Highly compressed air is delivered to the combustion chamber 16 . Airflow (not shown in FIG. 1 ) from combustor 16 drives turbines 18 and 20 which in turn drive fan assembly 12 .

[0015] FIG. 2 shows a cross-sectional view of an exemplary embodiment of a rotor assembly 40 that may be used in a gas turbine engine, such as engine 10 shown in FIG. 1 . FIG. 3 is a partial perspective view of an exemplary unmounted bearing assembly 4...

Abstract

A bearing assembly (42) for a gas turbine engine rotor (40) includes an annular spring (54) configured to support the gas turbine engine rotor, and an annular damper (120) bearing concentrically aligned with said annular spring, said damper bearing radially outward from said annular spring and configured to support said spring, at least one of said damper bearing and said spring comprising at least one groove (80) defined therein, at least one of said damper bearing and said spring comprising a retainer (140) extending therefrom, said at least one groove sized to receive said retainer therein for coupling said damper bearing to said spring.

Description

technical field [0001] The present invention relates generally to a gas turbine engine rotor assembly and, in particular, to a bearing assembly for a gas turbine engine rotor assembly. Background technique [0002] A gas turbine engine generally includes a fan rotor assembly, a compressor, and a turbine. The fan rotor assembly includes a fan with a set of fan blades extending radially outward from the rotor shaft. The rotor shaft, which transmits power and rotational motion from the turbine to the compressor and fan, is supported longitudinally by multiple bearing assemblies. The bearing assembly supports the rotor shaft and typically includes rolling elements positioned between an inner race and an outer race. [0003] Additionally, at least some known damped bearing assemblies include a plurality of resilient members coupled between the bearing outer race and the retaining flange. The resilient member supports the bearing and acts as an anti-rotation mechanism that subs...
