Power ultrasonic transducer

摘要

A power ultrasonic transducer according to the present invention includes: an ultrasonic generator (3) comprised of two pairs of piezoceramic elements (4) which are adjoined to be coupled to each other on the same shaft and a countermass (5) attached at the both ends of the piezoceramic elements (4); a hollow type body (2) having a length of integer times of half wavelength, in which the ultrasonic generator (3) is positioned; a cylindrical transmitting rod (6) having a length of integer times of half wavelength and for connecting the one side of the body (2) with the one side of the ultrasonic generator (3) to be fixed on the both sides of the ultrasonic generator (3), respectively; and a threaded stud (7) for securing an electric wire (8) for power supply at the one side end of the outside of the body (2), the electric wire (8) for power supply passing through the countermass (5) and the interior of the transmitting rod (6) each positioned in the interior of the body (2) to be wired to the piezoceramic elements (4).
