Abstract
The invention discloses a shafting slewing device which comprises a magnetic assembly, a bearing, a rotating component and a fixed component, the fixed component and the rotating component rotate relatively through the bearing, and the magnetic assembly is a permanent magnet or an electromagnet fixed to the fixed component and / or the rotating component. Wherein the magnetic assemblies attract the fixed part or the rotating part made of magnetic materials through magnetic force, or the magnetic assemblies arranged on the fixed part and the rotating part repel or attract each other through magnetic force. Through electromagnetic attraction, gravity or externally loaded load is counteracted, so that the bearing load is weakened, the fatigue load of the bearing is reduced, the service life of the bearing is greatly prolonged, and the operation stability of a mechanical structure is improved.
