Abstract

Embodiments of the present disclosure include a bearing housing of a turbine, wherein the bearing housing is configured to support a shaft of the turbine, and the bearing housing comprises at least one bearing housing ear configured to transfer a load of the bearing housing to an inlet housing of the turbine through a horizontal center line of the bearing housing.

First claim

The invention claimed is:

1. A system, comprising:
a bearing housing disposed within a turbine section of a machine, wherein the bearing housing is configured to support a shaft of the machine, and the bearing housing comprises at least one bearing housing ear configured to transfer a load of the bearing housing to an inlet housing of the turbine section of the machine through a horizontal center line of the bearing housing, wherein the at least one bearing housing ear comprises a contact face configured to engage with an ear recess of the inlet housing, wherein the contact face comprises an upper portion configured to be disposed on an upper side of the horizontal center line and a lower portion configured to be disposed on a lower side of the horizontal center line, wherein the upper and lower portions are symmetrical across the horizontal center line.

2. The system of claim 1 , wherein the load comprises a thrust load, and the at least one bearing housing ear comprises an upstream bearing housing ear.

3. The system of claim 1 , wherein the upper and lower portions have approximately equal cross-sectional areas.

4. The system of claim 1 , wherein the contact face extends across an entire width of the at least one bearing housing ear.

5. The system of claim 1 , wherein the at least one bearing housing ear comprises a metal shim coupled to a top surface of bearing housing ear.

6. The system of claim 5 , wherein the bearing housing ear comprises a recess formed in a front face of the bearing housing ear.

7. A system, comprising:
an inlet housing configured to receive a fluid flow, wherein the inlet housing is disposed in a turbine section of a machine; and
a bearing housing disposed within the inlet housing, wherein the bearing housing is configured to support a shaft, and the bearing housing comprises a plurality of ears configured to transfer an axial load from the bearing housing to the inlet housing through a horizontal center line of the bearing housing, wherein each of the plurality of ears comprises a contact face configured to engage with an ear recess of the inlet housing, wherein the contact face comprises an upper portion configured to be disposed on an upper side of the horizontal center line and a lower portion configured to be disposed on a lower side of the horizontal center line, wherein the upper and lower portions are of approximately equal size.

8. The system of claim 7 , wherein the plurality of ears comprises a first plurality of ears and a second plurality of ears, wherein the first plurality of ears is disposed at a first axial position along the bearing housing, the second plurality of ears is disposed at a second axial position along the bearing housing, and the first axial position is a forward axial position relative to the second axial position.

9. The system of claim 8 , wherein the axial load is a forward axial load, and the first plurality of ears is configured to transfer the axial load from the bearing housing to the inlet housing through the horizontal center line of the bearing housing.

10. The system of claim 7 , wherein the upper and lower portions form a continuous surface.

11. The system of claim 10 , wherein the upper and lower portions are symmetrical across the horizontal center line.

12. A system, comprising:
a turbine, comprising:
an inlet housing disposed within the turbine, wherein the inlet housing is configured to receive a fluid flow of the turbine, wherein the fluid flow comprises combustion products; and
a bearing housing disposed within the turbine, wherein the bearing housing is configured to support a shaft of the turbine, wherein the bearing housing comprises a bearing housing ear disposed within a bearing housing ear recess of the inlet housing, wherein the bearing housing ear is configured to transfer an axial load of the bearing housing to the inlet housing through a horizontal center line of the bearing housing, wherein the bearing housing ear comprises a contact face configured to engage with the hearing housing ear recess of the inlet housing, wherein the contact face comprises an upper portion configured to be disposed on an upper side of the horizontal center line and a lower portion configured to be disposed on a lower side of the horizontal center line, wherein the upper and lower portions are symmetrical across the horizontal center line.

13. The system of claim 12 , wherein the bearing housing ear comprises a non-contact face, the contact face is configured to transfer the axial load of the bearing housing to a forward surface of the bearing housing ear recess of the inlet housing, and the non-contact surface is configured to be offset from the forward surface of the bearing housing ear recess.

14. The system of claim 13 , wherein the contact face extends across an entire width of the bearing housing ear.

15. The system of claim 13 , wherein the bearing housing ear comprises a shim coupled to a top surface of the bearing housing ear and a front face of the bearing housing ear, and the front face of the bearing housing ear comprises a recess formed below the contact face.
