Abstract
Official abstract text for this publication.
Removing a generator core ( 10 ) from a frame ( 24 ) includes removing electrical and mechanical connections between the core and components external to the frame; installing a lift support assembly ( 34, 38, 42, 46 ) outboard of the core at each of an exciter end and a turbine end of the frame; installing a pilot shaft support assembly ( 50, 70, 73 ) between an inner surface of a core bore ( 10 D) and an outer surface ( 40 A) of a pilot shaft ( 40 ) at each of the exciter end and the turbine end of the frame; installing the pilot shaft through the first and second pilot shaft support assemblies and the core bore, the pilot shaft supported by the lift support assembly at the exciter end and the turbine end; decoupling the core and the frame; and activating a force-producing device ( 90 ) to slide the core out of the frame.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for removing a generator core, with windings, from a generator frame, the method comprising: removing electrical and mechanical connections between the core and components external to the frame; after the removing step, installing a first lift support assembly outboard of the core at an exciter end of the frame and installing a second lift support assembly outboard of the core at a turbine end of the frame; installing a first pilot shaft s…
