Abstract

A connector assembly to connect a swashplate and a rotor shaft or hub is provided. The connector assembly includes a mount configured to fixedly connect to the rotor shaft or hub, a sleeve pivotably attached to the mount, and a translating element translationally retained within the sleeve and configured to engage with the swashplate such that the swashplate and the rotor shaft or hub rotate at the same rotational speed.

First claim

What is claimed is:

1. A connector assembly to connect a swashplate and a rotor shaft or hub, the connector assembly comprising:
a mount configured to fixedly connect to the rotor shaft or hub;
a sleeve having a first orifice at a first end and a second orifice at a second end, and pivotably attached to the mount;
a translating element translationally retained within the sleeve and configured to engage with the swashplate such that the swashplate and the rotor shaft or hub rotate at the same rotational speed;
a first bearing cartridge arranged radially inward from the first end the sleeve; and
a second bearing cartridge arranged radially inward from the second end the sleeve,
wherein each bearing cartridge is configured such that the translating element is retained and moveable within the sleeve.

2. The connector assembly of claim 1 , further comprising a pivot to pivotably attach the sleeve to the mount.

3. The connector assembly of claim 2 , wherein the pivot is integrally formed with the sleeve.

4. The connector assembly of claim 1 , wherein the translating element includes a bearing interface configured to rotationally engage with the swashplate.

5. The connector assembly of claim 1 , wherein the mount is configured to be driven at the rotational speed by the rotor shaft or hub, and wherein the translating element is configured to drive the rotary element of the swashplate at the rotational speed.

6. The connector assembly of claim 1 , wherein the mount comprises at least two components.

7. The connector assembly of claim 1 , wherein the rotor shaft or hub is a component within a rotary-wing aircraft.

8. A swashplate assembly for use with a rotor shaft or hub, the assembly comprising: a rotary element;
a stationary element operationally connected to the rotary element; and
a connector assembly configured to operationally connect the rotary element to the rotor shaft or hub, wherein the connector assembly comprises:
a mount configured to fixedly connect to the rotor shaft or hub; a sleeve having a first orifice at a first end and a second orifice at a second end, and pivotably attached to the mount; and
a translating element translationally retained within the sleeve and configured to engage with the rotary element such that the rotary element and the rotor shaft or hub rotate at the same rotational speed;
a first bearing cartridge arranged radially inward from the first end the sleeve; and
a second bearing cartridge arranged radially inward from the second end the sleeve,
wherein each bearing cartridge is configured such that the translating element is retained and moveable within the sleeve.

9. The swashplate assembly of claim 8 , further comprising a pivot to pivotably attach the sleeve to the mount.

10. The swashplate assembly of claim 9 , wherein the pivot is integrally formed with the sleeve.

11. The swashplate assembly of claim 8 , wherein the translating element includes a bearing interface configured to rotationally engage with the rotary element.

12. The swashplate assembly of claim 8 , wherein the mount is configured to be driven at the rotational speed by the rotor shaft or hub, and wherein the translating element is configured to drive the rotary element at the rotational speed.

13. The swashplate assembly of claim 8 , wherein the mount comprises at least two components.

14. The swashplate assembly of claim 8 , wherein the rotor shaft or hub is a component within a rotary-wing aircraft.

15. The swashplate assembly of claim 8 , further comprising one or more control rods connected to the rotary element and configured to adjust a pitch of a blade.

16. The connector assembly of claim 1 , wherein the translating element is arranged to extend through the first orifice and the second orifice.

17. The swashplate assembly of claim 8 , wherein the translating element is arranged to extend through the first orifice and the second orifice.
