摘要： A form-fitting eddy current array probe for inspecting helical gears is provided, the probe comprising: a leg which includes a sensor zone with a plurality of eddy current arrays; an arm attached to and normal with the leg to provide an L-shaped probe, the arm including a sensor zone with a plurality of eddy current arrays; a resilient layer underlying the sensor zones; a gel layer attached to an upper surface of the sensor zones, the gel layer including a fluid gel and an outer covering encasing the fluid gel; and an encoder distally located on the leg. A method of inspecting a girth gear set including a helical gear and a girth gear using the form-fitting eddy current array probe is also provided.
