Abstract
A method and system for ultrasonically inspecting a ring gear of a gearbox is provided. The method and system can be used for the detection, characterization and/or sizing of defects in the ring gear. The ring gear has a plurality of teeth, which extend radially inward with respect to an outer surface of the gearbox. The method includes the steps of selecting an ultrasonic transducer productive of a test signal, positioning the ultrasonic transducer at an outer surface of the ring gear, orienting the ultrasonic transducer so as to direct the test signal to propagate through the ring gear, and activating the ultrasonic transducer so as to test the ring gear for defects therein.
