Abstract
Systems and methods are disclosed herein for bearings in a gas turbine engine. A bearing system may include a squirrel cage and a bearing support cage coupled to the squirrel cage. The bearing support cage may include an outer race and a fenestrated cone. The bearing support cage may include a support cage anti-rotation tab adjacent to the outer race. The bearing system may include a housing coupled to the squirrel cage. The housing may include a housing anti-rotation tab. The support cage anti-rotation tab and the housing anti-rotation tab may prevent the bearing system from twisting.
Claims20
A bearing system comprising:
- a squirrel cage;
- and
- a bearing support cage coupled to the squirrel cage, the bearing support cage comprising an outer race, a plurality of bearing support cage beams, and a support cage anti-rotation tab adjacent to the outer race.
A bearing system comprising:
- a bearing support cage comprising:
- a support cage flange;
- an outer race;
- a fenestrated cone adjoining the support cage flange and the outer race;
- and
- a support cage anti-rotation tab adjacent to the outer race;
- a squirrel cage comprising:
- a squirrel cage support flange;
- a fenestrated cylinder;
- and
- a housing flange;
- and
- a housing coupled to the housing flange, wherein the housing comprises a housing anti-rotation tab.
A gas turbine engine comprising:
