Bearing assemblies for a turbomachine

A bearing assembly for a turbomachine, the turbomachine including a rotating shaft extending along a centerline axis and a fixed housing positioned exterior to the rotating shaft in a radial direction relative to the centerline axis, the bearing assembly comprising:

• a first race statically coupled to the rotating shaft;
• a second race disposed between the first race and the fixed housing;
• a bearing cage having a first axial end portion, a second axial end portion, and an annular body extending between the first axial end portion and the second axial end portion, wherein the bearing cage is disposed between the first race and the second race;
• a bearing element disposed within the bearing cage and extending between the first race and the second race;
• and
• a first channel extending from the first axial end portion of the bearing cage towards an axial centerline of the bearing cage and a second channel extending from the axial centerline of the bearing cage to either the first axial end portion or the second axial end portion of the bearing cage;
• wherein the first channel and the second channel extend radially through the bearing cage;
• and wherein when the turbomachine is in an operational state, air flows radially outwards through the first channel and a mixture of air and lubricant flows radially outwards through the second channel.

A turbomachine comprising:

• a rotating shaft extending along a centerline axis and a fixed engine housing positioned exterior to the rotating shaft in a radial direction relative to the centerline axis;
• and
• a bearing assembly comprising:
• a first race coupled to the rotating shaft that rotates along with the rotating shaft in a first rotational direction when the turbomachine is in an operational state;
• a second race disposed between the first race and the fixed engine housing,
• an annular bearing cage positioned between the first race and the second race, comprising a bearing slot, and configured to rotate relative to the first race and the second race;
• a radial gap between the bearing cage and the second race;
• a first channel extending radially through the second race and a second channel extending axially through the fixed engine housing to a bearing compartment;
• and
• at least one bearing element disposed in the bearing slot;
• wherein when the turbomachine is in the operational state, air flows through the radial gap to the bearing slot and a mixture of air and lubricant flows through the first channel and the second channel away from the bearing slot and to the bearing compartment.
