DAMPING SYSTEM FOR A TURBOMACHINE SLIP RING

摘要

A damping system for a turbomachine slip ring includes a slip ring assembly. The slip ring assembly includes a rotating component which is coupled at one end to a rotor shaft of the turbomachine and a stator component which circumferentially surrounds a rotatable center core portion of the rotating component. The system further includes a static structure which defines a carrier sleeve where the carrier sleeve circumferentially surrounds a portion of the stator component. The system also includes a damping material which extends radially between an inner surface of the carrier sleeve and an outer surface of the stator component so as to dissipate vibrational energy of the slip ring assembly during rotation of the rotor shaft.

1. A damping system for a turbomachine slip ring, comprising:
a slip ring assembly including a rotating component coupled at one end to a rotor shaft of the turbomachine and a stator component circumferentially surrounding a rotatable center core portion of the rotating component, wherein the stator component is axially spaced from the coupled end of the rotating component; a static structure including a carrier sleeve, the carrier sleeve circumferentially surrounding a portion of the stator component; and a damping material, the damping material extending radially between an inner surface of the carrier sleeve and an outer surface of the stator component, wherein the damping material dissipates vibrational energy of the slip ring assembly during rotation of the rotor shaft.
