Embodiment Construction

[0015] The invention is a longitudinal-bending composite ultrasonic linear motor developed based on the use of the piezoelectric effect of the piezoelectric ceramic sheet to excite the longitudinal and bending vibration modes of the stator. It is mainly composed of stator and mover. It can be seen from the figure that the longitudinal bending composite ultrasonic linear motor of the present invention adopts a stator with a conical structure, and the stator is composed of eight symmetrically distributed piezoelectric ceramic gaskets 4 acting on the shifting teeth 6 through the double nuts 7 at both ends of the stator and then passing through the pressure shaft sleeve 5 Press the piezoelectric ceramic gasket 4 onto the stud shaft 2. The double nut 7 structure is adopted to ensure the anti-loosening and locking of the ultrasonic linear motor during operation. The shifting tooth 4 adopts a structure in which both sides are convex-shaped and slotted in the middle for the installat...

Abstract

The invention relates to one tamper stator longitude compound supersonic line motor, which adopts tamper stator and dial tooth adopt the middle structure with protruding benches for rotor fixing, sliding and guiding; the stator acts on dial tooth through symmetric distributed eight piezoelectricity pads through pressure axis cover to tighten the pads into spiral middle axis; the stator two ends adopt double screw loose to adjust stator pre-pressure and sets screw bolt through pressure board to press rotor for positive pressure.

Description

technical field [0001] The invention belongs to an ultrasonic motor in the field of micro-motors, in particular to an ultrasonic linear motor with a conical stator longitudinal bending composite type. Background technique [0002] Ultrasonic linear motor, as a new type of micro-actuator, breaks through the concept of traditional motors, and uses the inverse piezoelectric effect of piezoelectric ceramics and ultrasonic vibration of elastic bodies to convert microscopic deformation into rotor or slide through resonance amplification and electromechanical coupling.
