Abstract

The invention discloses a longitudinal vibration sandwiched transducer-based piezoelectric ultrasonic driver and an application method thereof. The piezoelectric ultrasonic driver comprises a horizontally-arranged base, two adjustment seats, a stator mechanism and a rotor, wherein the stator mechanism comprises two longitudinal vibration sandwiched transducers, the two longitudinal vibration sandwiched transducers are rotatably and symmetrically arranged around an axis of a flange shaft, and included angles among driving feet of the longitudinal vibration sandwiched transducers, a tangent direction of a rotor contact point and telescopic directions of the longitudinal vibration sandwiched transducers are smaller than 90 degrees. The application method comprises the following steps of 1, assembling and adjusting the piezoelectric ultrasonic driver; and 2, applying a sine excitation voltage by the longitudinal vibration sandwiched transducers and allowing the rotor to rotate. The piezoelectric ultrasonic driver is simple in structure, single-mode driving is achieved, and the piezoelectric ultrasonic driver is mainly used for solving the problems that a piezoelectric ultrasonic driverin a composite mode such as longitudinal vibration, bending vibration, longitudinal vibration and torsional vibration requires a simplified mode and is complicated in structure design and mass production is difficult to achieve.

Description

technical field [0001] The invention belongs to the technical field of piezoelectric ultrasonic drivers, and in particular relates to a piezoelectric ultrasonic driver based on a longitudinal vibration sandwich transducer. Background technique [0002] Piezoelectric ultrasonic actuator is a new type of actuator that uses the inverse piezoelectric effect of piezoelectric materials to convert electrical energy into mechanical energy. The stator is usually a composite elastic body composed of piezoelectric ceramics and metal elastomers. By applying an AC voltage of ultrasonic frequency to the piezoelectric ceramics, the mechanical vibration of the same frequency in the stator elastic body is realized, and then the particle formation in the stator drive area has a driving effect. The motion trajectory of the rotor is further achieved through the frictional coupling between the stator and the rotor to achieve the output of the macroscopic motion of the rotor. It has the advantag...
