POWER TURBINE SHAFT WITH HUB ASSEMBLY FOR GAS TURBINE ENGINE

Conventionally, trim balancing for a power turbine has been performed at the equipment coupling. Disclosed embodiments comprise a hub that is installed on the shaft. This hub enables trim balancing to be performed on the shaft coupling, closer to the rotor, which is more effective. The disclosed hub...

Beschreibung
Zusammenfassung:	Conventionally, trim balancing for a power turbine has been performed at the equipment coupling. Disclosed embodiments comprise a hub that is installed on the shaft. This hub enables trim balancing to be performed on the shaft coupling, closer to the rotor, which is more effective. The disclosed hub also enables unbalance corrections to remain with the power turbine after uncoupling. In addition, the use of the hub improves efficiency and eliminates safety risks faced by personnel in the field during coupling of the power turbine to the equipment.
