Problems solved by technology

The problem is: the load of various workpieces on the casing has a certain weight, so that the bearing bears a large axial force, which increases the wear of the bearing and shortens the service life of the bearing
At the same time, due to the increased friction of the bearing, the mechanical energy is lost and the efficiency of the mechanism is reduced.

Abstract

The invention relates to a vertically pivoted rotary mechanism of a magnetic suspension device, which comprises a vertical shaft, a bearing and a shell, wherein, the shell is composed of an upper supporting plate and a lower supporting plate which are arranged top down and a boarding positioned between the upper supporting plate and the lower supporting plate rotates; the vertical shaft is pivoted on the upper supporting plate and the lower supporting plate by the bearing and the lower end of the vertical shaft is fixed on a supporting base; the shell rotates with loaded work pieces. The rotary mechanism is characterized in that the mechanism also comprises a stator fixed on the vertical shaft and a rotor fixed on the shell and a clearance is left between the stator and the rotor. By adopting the structure, magnetic pulling force between the stator and the rotor offsets the axial force of the vertical shaft generated by work piece loading, guarantees that the inner ring and the rolling body of the bearing are arranged at the axial center of the bearing, reduces the wearing of the bearing and prolongs the service life. Therefore, the mechanism can effectively solve the problem of axial force borne by the bearing, prolong the service life of the bearing and improve the mechanical efficiency.
