ULTRASONIC ROLLING TRANSDUCER FOR NON-DESTRUCTIVE TESTING Russian patent published in 2023 - IPC G01N29/04 

FIELD: ultrasonic non-destructive testing.

SUBSTANCE: invention is intended for ultrasonic non-destructive testing. The substance of the invention lies in the fact that the ultrasonic rolling transducer for non-destructive testing contains a U-shaped body, a hollow cylindrical piezoelectric element, a protector installed with the possibility of rotation around its own axis, sliding current collectors installed in the body, while the body made of steel is detachable in a plane passing through the plane of rotation of the piezoelectric element, and consists of two parts, which are isolated from each other by means of an electrically insulating gasket, while in one of the parts of the housing there is a connector with wires connected to each of the parts of the housing for electrical supply of copper-based alloy current collectors installed inside the coaxial holes of the body and electrically connected to the piezoelectric element, while between the piezoelectric element and the protector a thin-walled cylinder made of tool carbon steel is installed and rigidly attached to them.

EFFECT: simplification of the design of the transducer, as well as increasing the reliability of the electrical contact between the rotating cylindrical piezoelectric element and the sliding current collectors of the transducer.
