ABSTRACT:
The invention relates to a driving device for at least two rotation elements, which device comprises at least one piezoelectric driving element. The object of the invention is to provide such a driving device having a high efficiency and allowing a more flexible positioning of the rotation elements.
The invention is characterized in that the piezoelectric driving element comprises a piezoelectric resonator and at least two friction elements arranged on the piezoelectric resonator and disposed opposite one another, the piezoelectric resonator with the friction elements is arranged between the two rotation elements and is restrained by means of a pre-loading force, each one of the friction elements acts upon one of the rotation elements, and electrical means for the excitation of a vibration mode of the piezoelectric resonator have been provided.
