Title: Rotary drive device
Inventor: OOTSUKI KUNIO
IPC: H01L41/09
Filed: 1983-07-06
Abstract: PURPOSE:To rotate a rotor by the vibration energy of a supersonic vibrator by coupling a rotor rotatably supported and the vibrator through a mechanism for converting a linear vibration into a rotary vibration. CONSTITUTION:A high frequency vibrator 6 is fixedly provided near a rotor 5, the rotor 5 and the vibrator 6 are coupled through a mechanism 7 for converting a linear vibration into a rotary motion, thereby rotating the rotor 5 by the vibration energy of the vibrator 6. In other words, when a rod-member 8 is linearly vibration in Y direction of axial center by the vibrator 6, the end intermittently repeatedly presses a disc 4 in a high frequency, and the disc 4 and hence the entire rotor 5 rotates. Thus, high rotary efficiency and stable rotary performance can be obtained.
