1. A kind of 1. clamper power is adjustable tangential driving rotatory inertia formula piezoelectric actuator, it is characterised in that:

  • Major part includes bottomThe driving mechanism that seat (1), bearing (2), shell (17) and two antisymmetry are arranged, total have rotational symmetry, internalContain through hole;

    Inner ring gasket (15) is adhered on the inner ring of bearing (2), is fixed to by screw on base (1);

    Bearing (2)Outer ring and race gasket (16) bonding, race gasket (16) are fixed by screw and shell (17);

    The drive of two antisymmetry arrangementsMotivation structure includes the first diamond shape ring (3) and the second diamond shape ring (10) and is separately mounted to the first diamond shape ring by interference fit(3) and the first piezoelectric pile (4) and the second piezoelectric pile (9) in the second diamond shape ring (10);

    First diamond shape ring (3) and the second diamond shape ring(10) one end is friction side, is engaged with the outer peripheral surface of bearing (2) by face, and the other end is fixing end, fixing end bottomProtrusion, is fixed on base (1), and the part in addition to fixing end is hanging, is not contacted with base (1);

    First bullet of arc-shapedProperty element (5) and the second flexible member (11) one end respectively with the first diamond shape ring (3) and second diamond shape ring (10) abrasive end face phaseTo face contact, the other end is separately fixed on the first adjusting block (6) and the second adjusting block (12);

    First adjusting block (6) andTwo adjusting blocks (12) are contacted with the first boss (7) on base (1) and second boss (13) respectively;

    First boss (7) and secondThreaded hole is provided with boss (13), the first screw (8) and the second screw (14) pass through first boss (7) and second boss respectively(13) threaded hole on extrudes the first adjusting block (6) and the second adjusting block (12), makes the first flexible member (5) and the second elasticity memberPart (11) is deformed, so as to change the positive pressure between the first diamond shape ring (3) and the second diamond shape ring (10) and the outer ring of bearing (2)Power, plays the function of adjusting clamper power.
