Abstract

The present disclosure provides a torque tube comprising a barrel portion disposed between a flange and a back leg, the flange extending radially inward towards an axis of rotation and the back leg extending radially outward from the barrel portion. The torque tube further comprises a channel defined by a channel wall and disposed in at least one of the barrel portion and the flange, the channel being configured to receive a sacrificial member.

First claim

What is claimed is:

1. A torque tube comprising:
a barrel portion disposed between a flange and a back leg, the flange extending radially inward towards an axis of rotation and the back leg extending radially outward from the barrel portion; and
a channel defined by a channel wall and disposed in at least one of the barrel portion and the flange, the channel being configured to receive a sacrificial member; and
a torque tube foot disposed on an inner diameter of the barrel portion, the torque tube foot comprising at least one of a groove or an aperture configured to receive the sacrificial member.

2. The torque tube of claim 1 , wherein the channel wall comprises an obtuse-angled edge.

3. The torque tube of claim 1 , wherein the channel wall comprises an acute-angled edge.

4. The torque tube of claim 1 , wherein the channel is disposed in an outer diameter of the barrel portion.

5. The torque tube of claim 4 , wherein the channel extends in an axial direction at least partially between the flange and the back leg.

6. The torque tube of claim 5 , further comprising:
a first spline disposed on the outer diameter of the barrel portion; and
a second spline disposed on the outer diameter of the barrel portion and substantially parallel to the first spline, wherein the channel extends in a radial direction at least partially between the first spline and the second spline.

7. A torque tube assembly comprising:
a torque tube having a barrel portion disposed between a flange and a back leg, the flange extending radially inward towards an axis of rotation and the back leg extending radially outward from the barrel portion; and
a sacrificial member disposed on at least one of the flange and a torque tube foot, the torque tube foot being disposed on an inner diameter of the barrel portion, wherein a friction face of the sacrificial member is in frictional contact with the inner diameter of the barrel portion.

8. The torque tube assembly of claim 7 , wherein the sacrificial member comprises a carbon composite material.

9. The torque tube assembly of claim 7 , further comprising a rivet configured to couple the sacrificial member to at least one of the flange and the torque tube foot.

10. The torque tube assembly of claim 7 , wherein the sacrificial member is disposed on the flange and extends in an axial direction at least partially between the flange and the torque tube foot.

11. The torque tube assembly of claim 10 , further comprising:
a channel defined by a channel wall and disposed in the flange, wherein the sacrificial member is at least partially disposed in the channel.

12. The torque tube assembly of claim 11 , wherein the channel wall comprises an obtuse-angled edge.

13. The torque tube assembly of claim 11 , wherein the channel wall comprises an acute-angled edge.

14. The torque tube assembly of claim 7 , wherein the sacrificial member is disposed on the torque tube foot and extends in an axial direction at least partially between the torque tube foot and the flange.

15. A torque tube assembly comprising:
a torque tube comprising a barrel portion disposed between a flange and a back leg, the back leg extending radially outward from the barrel portion, and a channel defined by a channel wall and disposed in an outer diameter of the barrel portion; and
a sacrificial member disposed in the channel, wherein a friction face of the sacrificial member is in frictional contact with the channel, and
wherein the channel wall comprises an obtuse-angled edge.

16. The torque tube assembly of claim 15 , wherein the channel extends in an axial direction at least partially between the flange and the back leg.

17. The torque tube assembly of claim 15 , further comprising:
a first spline disposed on an outer diameter of the barrel portion; and
a second spline disposed on the outer diameter of the barrel portion and substantially parallel to the first spline, wherein the channel extends in a radial direction at least partially between the first spline and the second spline.

18. A torque tube assembly comprising:
a torque tube comprising a barrel portion disposed between a flange and a back leg, the back leg extending radially outward from the barrel portion, and a channel defined by a channel wall and disposed in an outer diameter of the barrel portion; and
a sacrificial member disposed in the channel, wherein a friction face of the sacrificial member is in frictional contact with the channel, and
wherein the channel wall comprises an acute-angled edge.

19. The torque tube assembly of claim 18 , further comprising:
a first spline disposed on an outer diameter of the barrel portion; and
a second spline disposed on the outer diameter of the barrel portion and substantially parallel to the first spline, wherein the channel extends in a radial direction at least partially between the first spline and the second spline.
