Abstract:
    This invention relates to a precision rotating unit driven by piezoelectric dual-wafers and its device including two sets of dual-wafer actuating pieces, two sets of sway bars, two clutches, an output shaft and a base, in which, the output shaft is supported on the base by a sliding bearing, the two clutches are composed of driven and driving components, the driven component is fixed on the output shaft, the two driving components are set at both ends of the driven one covering on the shaft, the two sets of sway bars are set at both sides of the two clutches with two shift plates and a jacket for each set, the two shifting plates are fixed at either end of the jacket, one of the shifting plates is fixed to the driving piece, two sets of the piezoelectric dual-wafer activating components are set at either sides of the two clutches composed of fixedly connected piezoelectric dual-wafers and a pin shaft, one end of the dual-wafer is fixed to the shaft and the other end is fixed on the base and the grooves of the shaft and the shifting plates are matched to constitute a plane higher pair.
