A device for non-destructive testing by an eddy-current transducer of places of change in diameter and mating lines of structural elements of stepped shafts and other test objects shaped like bodies of revolution

摘要

The utility model refers to non-destructive testing of products and is intended for flaw detection of stepped shafts and other objects of inspection, which have the shape of bodies of revolution for the presence of cracks and other discontinuities using an eddy current transducer.;The aim of the proposed technical solution is to create the most simple device for non-destructive testing of places of change in diameter and mating lines of structural elements of stepped shafts and other objects of control, which have the form of bodies of revolution. It is difficult to control these zones with an eddy current transducer by the presence of false signals. At the same time, fatigue cracks, being one of the most dangerous defects, develop precisely at the points of profile fracture.;Non-destructive testing of OK using the proposed devices in the form of a set of technological equipment is applicable when the use of automated complexes is economically inexpedient. In addition, this useful model can be a supplement to automated complexes, since it is quite difficult to properly set up this work on an automated complex.
