More Information
Summary:A balancing assembly for a gas turbine hollow drive shaft is disclosed. The balance assembly includes an expandable balance weight carrier and a device for expanding the carrier inside the hollow drive shaft. In a preferred embodiment the carrier comprises a split ring with a plurality of apertures at which balance weights can be received. Combinations of balance weights can be located around the carrier ring to establish an imbalance correction on the carrier. The carrier can then be positioned inside the shaft and expanded against the shaft with the imbalance correction directed opposite the shaft imbalance.
