摘要： 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.

摘要： An ultrasonic probe is used to inspect wheel and bucket dovetails of turbines for cracks in the material surrounding pinholes and pins securing the buckets and wheel to one another. Only a minimum number of pins, for example, one of three radially aligned pins securing the bucket and wheel dovetails to one another at every other circumferential position of the pins about the wheel may be removed. A phased array ultrasonic probe is inserted into the excavated pinhole and provides a circumferential scan of the finger dovetails to detect cracks in adjacent pinholes. As an alternative, a probe having one or more piezoelectric elements providing one or more radial beams may be mechanically rotated in the pinhole. Statistical sampling may be used as an indicator of crack formation. Thus, in situ inspection is performed without removal of buckets from the wheel and with only a minimum number of pins being removed.
