Abstract
A system includes a rotor shaft rotatable about an axis, a disconnect shaft nested at least partially within an interior of the rotor shaft, and a journal shaft selectively rotatably coupled to the disconnect shaft. A vibration damping mechanism is arranged between the rotor shaft and the journal shaft. The vibration damping mechanism includes a thrust journal bearing affixed to the rotor shaft and a thrust washer mounted to the journal shaft. A biasing mechanism is operably coupled to disconnect shaft to bias the thrust washer into frictional engagement with the thrust journal bearing.

A system comprising:
- a rotor shaft rotatable about an axis;
- a disconnect shaft nested at least partially within an interior of the rotor shaft;
- a journal shaft selectively rotatably coupled to the disconnect shaft;
- a vibration damping mechanism arranged between the rotor shaft and the journal shaft, the vibration damping mechanism including a thrust journal bearing affixed to the rotor shaft and a thrust washer mounted to the journal shaft;
- and
- a biasing mechanism operably coupled to the disconnect shaft to bias the thrust washer into frictional engagement with the thrust journal bearing.
A method of assembling a vibration damping assembly comprising:
- providing a journal shaft;
- providing a collar and at least one thrust journal bearing affixed to the collar, the collar being connectable to a rotor shaft and the journal shaft being nested within the rotor shaft;
- aligning a thrust washer with an end of the journal bearing;
- and
- pressing the thrust washer onto the journal bearing to a position where the thrust washer is engaged with the at least one thrust bearing.
