Embodiment Construction

[0024] The accompanying drawings disclose, without limitation, the structural schematic diagrams of the preferred embodiments involved in the present invention; the technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0025] Such as figure 1 and figure 2 As shown, the micro-nanomotor of the present invention includes a clamping mechanism, a shear piezoelectric ceramic driver, a pre-tensioning mechanism and an output member, wherein:

[0026] The output member is a hollow cuboid. Among the two sets of opposing planes extending along the length direction of the hollow cuboid, one of them is a driving surface, and the other is a non-driving surface. The non-driving surface The corresponding board surface is hollowed out, and this application opens the corresponding board surface of the non-driving surface into a frame-like structure; in this application, the output part is made of metal titanium, and of c...

Abstract

The invention discloses a miniature nanomotor based on a shearing piezoelectric effect. The nanomotor comprises a clamping mechanism, a shearing piezoelectric ceramic actuator, a pre-tightening mechanism and an output piece. The shearing piezoelectric ceramic actuator is in contact with the driving surface of the output piece through the pre-tightening force of the pre-tightening mechanism applied to the clamping mechanism. The output piece is of a hollow structure, and all surfaces of the output piece parallel to the proceeding direction are hollow board surfaces except the driving surface. Therefore, the weight of the output piece can be reduced to the largest extent, the driving capability of a shearing piezoelectric stacking motor is improved, and the motor can walk under low voltage under lower temperature. Meanwhile, the nanomotor has a larger stepping journey and can drive the output piece and parts on the output piece to achieve large-journey advancing and retreating in a centimeter range.
