# Thrust ring frictional damper

## 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.
