METHOD AND APPARATUS FOR SUPPORTING ROTOR ASSEMBLIES DURING UNBALANCES
摘要
A rotor assembly (40) for a gas turbine engine (10) includes a bearing assembly (46) that reduces dynamic loads to a support frame (44) and static bending to the rotor assembly during periods of rotor imbalance. The rotor assembly includes a rotor shaft (42) coupled to a fan (12) and supported longitudinally with a plurality of bearing assemblies on a support frame. A number two bearing assembly includes a paired race (50), a bearing (48), and a mounting race (102). The mounting race includes a spherical face and is secured to the bearing assembly with a retainer (104) that plastically fails at a pre-determined moment load.
