  • Bearing assembly
    Patent number: 9885386
    Abstract: A system includes a bearing assembly configured to be coupled to a compressor of a gas turbine engine and to receive an end of a torque shaft assembly, a bearing housing, and a circumferential bearing. The circumferential bearing includes a split race and a ball disposed within the split race. The circumferential bearing may be configured to be removed from the bearing housing without having to remove the torque shaft assembly from the compressor.
    Type: Grant

  • METHODS AND SYSTEMS FOR PREVENTING GAS TURBINE ENGINE LUBE OIL LEAKAGE
    Publication number: 20020166317
    Abstract: A sump evacuation system for a gas turbine facilitates reducing oil leakage from bearing assembly sumps in a cost-effective and reliable manner. The engine includes at least one bearing assembly housed within a sump pressurization cavity. The sump evacuation system includes a sump pressurization cavity, a sump oil cavity, an air/oil separator, and an air pump. The bearing assembly and the sump oil cavity are coupled in flow communication with the sump pressurization cavity, and the air/oil separator is coupled in flow communication with the sump oil cavity. Furthermore, the air pump is coupled in flow communication with the air/oil separator.
