ULTRASONIC OSCILLATING SYSTEM Russian patent published in 2006 - IPC B06B1/06 B06B3/02 

FIELD: ultrasonic engineering; designs of the ultrasonic oscillating systems.

SUBSTANCE: the invention is pertaining to the field of ultrasonic engineering, namely, to the designs of the ultrasonic oscillating systems. The technical result of the invention is the increase of the amplitude of oscillations at the simultaneous decrease of the power consumption, reduction of the overall dimensions and the mass. The ultrasonic oscillating system is made out of the packs of the piezoelectric components arranged on the oscillations forming surface of the concentrator. On the packs of the piezoelectic components there are the reflective straps, which surfaces opposite to the piezoelectic components are made flat or as varying steps in the diameter. The concentrator has the unit of fixation and ends with the surface having the working tool. The forming and emitting surfaces of the concentrator have in section the rectangular form of the equal length, and the ratio of their lateral dimensions is selected from the condition of provision of the preset factor of amplification of the concentrator. The total length of the reflective strap, the pack of the piezoelectic components and the concentrator section up to the assembly unit of fixation is equal to the sixth part of the wavelength of the ultrasonic oscillations. The length of section of the concentrator, on which the smooth radial transition is realized, and the section with the lateral dimension corresponding to the emitting surface are equal to the sixth part of the wavelength of ultrasonic oscillations.

EFFECT: the invention ensures the increase of the amplitude of oscillations at the simultaneous decrease of the power consumption, reduction of the overall dimensions and the mass.
