IPC: G11B21/02
Filed: 1989-09-25
Abstract: PURPOSE:To reduce frictional resistance in a bearing device which is utilized for a head access mechanism of a hard disc device or the like by oscillating a shaft or a housing rotatingly contacted to a ball bearing by means of agitating elements. CONSTITUTION:A housing 23 is rotatably supported to a ball bearing 22H. Piezoelectric plates 31B as agitating elements are adhered to a rotary shaft 21. The peizoelectric plates 31B are arranged on the four sides of a square through-hole 30 of a fixed shaft 21, while polarization is performed such that porilization direction of the adjacent piezoelectric plates are opposite to each other. Oscillating output is supplied from a resonance driving power to the piezoelectric plates to perform electrostriction operation on each of the piezoelectric plates. As a result the fixed shaft is under a resonance excitation condition. Under such a condition, frictional resistance of the ball bearing 22H is remarkably reduced.
