Abstract
A scanner assembly for dovetail inspection of the wheels of a turbine rotor includes a series of circumferentially pivotally connected links: a motor link, transmission links, an encoder link, an adjustable link, free links and a base link mounting a transducer. The motor link mounts a motor for driving rollers on the transmission links and rotating the scanner assembly about the rotor shaft. The encoder link mounts an encoder for determining the circumferential position of the transducer about the shaft. The adjustable link enables the assembly to be tightened or loosened about the rotor shaft. The free links and base link complete the circular scanner assembly about the shaft. A single scan for a full 360° investigates the plurality of hooks on the side of the wheel opposite the transducer.
