Abstract
The invention relates to an orthogonal transducer type cylindrical traveling-wave ultrasonic motor vibrator belonging to the technical field of piezoelectric ultrasonic motors and solving the problemsthat the mechanical output capability of a motor is restricted because the prior ultrasonic motor vibrator adopts a metal elastomer to bond piezoelectric ceramic thin plates to excite, and the mechanical output capability and the controllability of an ultrasonic motor are reduced because a plurality of transducers are driven simultaneously. The orthogonal transducer type cylindrical traveling-wave ultrasonic motor vibrator comprises a cylinder and an orthogonal transducer, wherein the orthogonal transducer is formed by orthogonally connecting amplitude rods of a first transducer and a secondtransducer into a whole, both sides of each transducer flange are respectively connected with screw posts which are respectively screwed with the amplitude rods and a rear end cover, the screw posts among the flange, the amplitude rods and the rear end cover are respectively sleeved with piezoelectric ceramic plates and electrode plates, insulating sleeves are arranged among the piezoelectric ceramic plates, the electrode plates and the screw posts, and a plurality of comb-shaped driving teeth are evenly distributed on the inner wall of the cylinder along a circumferential direction. The orthogonal transducer type cylindrical traveling-wave ultrasonic motor vibrator is used for the field of manufacturing ultrasonic motors.
