Experimental inspection of the contactless radiowave method for determining the technical condition of gear wheels

The article describes contactless radiowave method for monitoring the technical condition of gears. Shows the image of the experimental device. Some features of the use of primary transducers with different types of waves excited inside them are described. The experimentally obtained dependences of the amplitude on the distance between the end face of the primary transducer and the monitored surface are analyzed. On the basis of the analysis, conclusions were drawn as to which gap is preferable to use when installing the primary converter.
