Title: Ultrasonic vibrator
Inventor: IMABAYASHI HIROYUKI
IPC: H02N2/00
Filed: 1992-02-28
Abstract: PURPOSE:To reduce heat generation and to keep vibration amplitude max. by arranging a pair of electric-mechanical energy conversion elements to the loop position of bending vibration and providing a pair of resonators in the vicinity of both end surfaces of an ultrasonic vibrator so as not to come into contact with a clamping member. CONSTITUTION:When sine wave voltages mutually shifted in phase by a 1/4 wavelength are applied to a pair of electrode plates 3, 4, temporary bending vibration is generated and oval vibration rotating around a center axis is generated. When a rotor 8 is bonded to the end surface of one resonator 5 under pressure, an ultrasonic motor wherein the rotor 8 revolves is constituted. Cup- shape recessed parts 5a, 6a are formed in a pair of resonators 5, 6 in a both-end surface direction and the contact of the resonators with a clamp member 10 in the vicinity of both ends of the resonators is avoided. By this constitution, the rigidity of both resonators 5, 6 in the bending direction thereof is lowered and the effect due to the rigidity of the clamp member 10 is suppressed to the min. Then, vibration amplitude is set to max. at both end surfaces of an ultrasonic vibrator. The rotor 8 is always kept horizontal.
