Disclosed is a rotary type traveling-wave spherical
ultrasonic motor synchronous self-aligning
stator support device, comprising a
stator, a
stator support rod, a
strain gauge, a rotor, a cylindricalroller, a spherical roller , a rotating wheel, a fixed cylinder, a hinged support, a
soft metal ring, a
hard metal ring and a pedestal; the hinged support is arranged in the pedestal, wherein the hinged support winds the
central line of the pedestal for one circle at equal angles; the hinged support is connected with the stator through the stator support rod, and a
strain gauge is arranged on thestator support rod; the stator clamps the rotor, and the fixed cylinder is on the pedestal; the fixed cylinder is sleeved with the rotating wheel; the
hard metal ring is arranged in the annular groovein the upper part the rotating wheel; the
soft metal ring is in the
hard metal ring; a spherical roller is arranged between the bottom of the hard
metal ring and the bottom of the circular groove onthe upper part of the rotating wheel, and a cylindrical roller is arranged between the outer wall of the hard
metal ring and the inner wall of the circular groove on the upper part of the rotating wheel. The support device achieved by the invention can realize
synchronous control of all stator support rods, and can adjust the stator pre-loaded pressure quickly and conveniently, so that it has equivalent and appropriate pre-loaded pressure.
