Abstract

See full text

A micro inchworm-type piezoelectric-driven rotating joint mechanism includes a U-shaped base, bearing pedestals, bearing brackets, bearing rings, piezoelectric ceramic plates, a rotating shaft, a rotating sleeve and end caps. Every bearing ring is divided into two half-rings which are coupled to the bearing pedestals via two bearing brackets. One end of every piezoelectric ceramic plate is fixed to one bearing pedestal, and the other end thereof is coupled to one bearing ring, so that every piezoelectric ceramic plate stretches and deforms under the driving of voltage for driving the bearing ring to achieve micro motions. Two bearing driving modules are respectively symmetrically mounted at two sides of the U-shaped base, and the rotating shaft is supported on the two bearing rings, so that the stepping motion of the rotating shaft is implemented by controlling the timing sequence of clamping, release and rotation of the two bearing driving modules.
