MAGNETIC SUSPENSION TORSION PENDULUM MECHANISM

The utility model discloses a magnetic suspension torsion pendulum mechanism, belonging to the torsion pendulum mechanism of a clock, comprising a rotating shaft frame, a hair spring, an upper magnetic steel bracket, a lower magnetic steel bracket, magnetic steels, an upper magnetic ring, a lower magnetic ring, a rotating shaft, a coil and a torsion pendulum. The magnetic suspension torsion pendulum mechanism is characterized in that the lower part of the upper magnetic steel bracket and the upper part of the lower magnetic steel bracket are respectively and correspondingly provided with two pairs of magnetic steels with opposite magnetic poles, and two magnetic steels on the same one magnetic steel bracket respectively are symmetric, so that the magnetic suspension torsion pendulum mechanism with a four-pole structure can be constituted. The utility model has the advantages of symmetric magnetic fields, symmetric magnetic suspension forces, long service life and reliable working performance of the torsion pendulum. The magnetic ring is difficult to become ageing.
