Filed: 1993-09-22
Abstract: PURPOSE:To micronize an oscillatory wave driving device by subjecting a main and auxiliary oscillatory elastic bodies to d elliptic motions which are inverted in phase to each other and using both or either one of the main and auxiliary elastic bodies as an oscillatory energy outputting section. CONSTITUTION:When an alternating current is impressed upon a piezoelectric elements 2 having A- and B-phases, a main and auxiliary oscillatory elastic bodies 1 and 3 make similar oscillations with a phase shift of 90 deg. around the Z-axis. Therefore, when a 90 deg. temporal phase shift is given to the AC voltage applied across the A- and B-phases of the element 2, the driving surface 1a of the body 1 and flange section 3a of the body 3 make elliptic motions. In addition, progressive waves having a node diameter 1 or 2 are formed by the out-of-plane deformation of the element 2 at the driving section 1a of the body 1 and a rotor 4 which is press-contacted with the section 1a is rotated by friction. The rotational force of the rotor 4 is transmitted to an output member 7 and the output of the member 7 is fetched through a gear section 12a.
