Bearing supports
A bearing support includes a squirrel cage including a fenestrated portion with a plurality of circumferentially spaced apart windows defined therethrough. A bearing support cage inboard of the squirrel cage defines a plurality of circumferentially spaced apart windows therethrough. The bearing support cage is operatively connected to the squirrel cage to support a bearing from within the squirrel cage.
1. A bearing support comprising:
a squirrel cage including a fenestrated portion with a plurality of circumferentially spaced apart beams defined therein; and
a bearing support cage inboard of the squirrel cage, the bearing support cage defining a plurality of circumferentially spaced apart beams therein, the bearing support cage being operatively connected to the squirrel cage to support a bearing from within the squirrel cage, wherein the bearing support cage extends from the fenestrated portion of the squirrel cage to the bearing.
2. A bearing support as recited in claim 1 , wherein the bearing support cage includes a bearing outer race configured to engage the bearing directly.
3. A bearing support as recited in claim 2 , wherein the squirrel cage, the bearing support cage, and the bearing outer race are all integral with one another.
4. A bearing support as recited in claim 3 , wherein the squirrel cage, the bearing support cage, and outer bearing race are all a single integral component.
5. A bearing support as recited in claim 2 , wherein there is a weld joint joining the squirrel cage to the bearing support cage.
6. A bearing support cage as recited in claim 2 , wherein there is at least one bolt joining the squirrel cage to the bearing support cage.
7. A bearing support as recited in claim 2 , wherein the bearing support cage is a separate component joined to the squirrel cage.
8. A bearing support as recited in claim 7 , wherein the bearing support cage includes M50NiL.
9. A bearing support as recited in claim 7 , wherein the squirrel cage includes titanium.
10. A bearing support as recited in claim 2 , wherein the bearing outer race is a separate component joined to the bearing support cage.
11. A bearing support as recited in claim 10 , wherein each of the bearing support cage and the bearing outer race includes a respective fastener flange extending therefrom, wherein the respective fastener flanges are joined together with fasteners.
12. A bearing support as recited in claim 10 , wherein the squirrel cage and bearing support cage are integral with one another.
13. A bearing support as recited in claim 10 , wherein the bearing outer race includes M50NiL.
14. A bearing support as recited in claim 10 , wherein the squirrel cage and bearing support cage each include titanium.
15. A bearing support as recited in claim 1 , wherein each circumferentially adjacent pair of the beams of the squirrel cage are separated by a squirrel cage window, wherein each circumferentially adjacent pair of the beams of the bearing support cage are separated by a support cage window, and wherein each of the squirrel cage beams is radially aligned with a respective one of the support cage beams.
16. A bearing support as recited in claim 1 , wherein each circumferentially adjacent pair of the beams of the squirrel cage are separated by a squirrel cage window, wherein each circumferentially adjacent pair of the beams of the bearing support cage are separated by a support cage window, and wherein the squirrel cage beams and the support cage beams all extended in an axial direction with respect to a longitudinal axis defined by the bearing support cage.
17. A bearing support as recited in claim 1 , wherein each circumferentially adjacent pair of the beams of the squirrel cage are separated by a squirrel cage window, wherein each circumferentially adjacent pair of the beams of the bearing support cage are separated by a support cage window, and wherein the squirrel cage beams all extend in an axial direction with respect to a longitudinal axis defined by the bearing support cage, and wherein the support cage beams extend obliquely with respect to the longitudinal axis.
