发明名称 ULTRASONIC MOTOR AND TORSIONAL OSCILLATION GENERATING DEVICE
摘要 PURPOSE:To simplify the drive power source section of an ultrasonic motor so as to make the best use of the excellent advantage that the motor originally has by forming a vibration converter means on a discoid elastic body provided with an electrostriction vibrator constituting a stator. CONSTITUTION:In an ultrasonic motor equipped with a stator 26 having a discoid elastic body 28 provided with an electrostriction vibrator 30 and a rotor 32 which is relatively slid on the stator 26 in a freely rotatable state, a vibration converting means is formed on the elastic body 28. For example, the sliding surfaces 31 and 33 of the stator 26 and rotor 32 on which the rotor 33 and elastic body 28 mutually slide on another are inclined against the plane of the elastic body 28 and a frictional material 34 is stuck to the sliding surface 33 of the rotor 32. In addition, the vibration converting means is composed of a plurality of slits formed inward from the outer periphery of the elastic body 28 and each slit 40 is formed so that an angle theta (10 deg.<theta<80 deg.) can be formed between the slit 40 and diametral direction of the elastic body 28.
