FIELD: electromechanics, applicable as a drive of various devices in precision instrument engineering, at medico-biological examinations and in radio-technology systems.
SUBSTANCE: the piezoelectric drive has a movable working T-section, linear piezoelectric elements, T-shaped support. The movable section and the support are so positioned that their horizontal elements face one another. The rod-like structure is made in the form of two isosceles trapezoids, which are interconnected in the centers of the smaller bases of the trapezoids via a piezoelectric element. The lateral sides of the trapezoids are installed for movement in the ring-shaped holders rigidly fastened at the ends of the horizontal elements of the T-shaped support and the movable T-section. The second piezoelectric element is installed on the movable T-section.
EFFECT: expanded range of displacements, enhanced accuracy.
