Magnetic structure of absorption coupling magnetic support system of cantilever type wind driven generator

The utility model relates to a magnetic structure of an absorption coupling magnetic support system of a cantilever type wind driven generator, which consists of a multi-form fixed magnet fixed on a machine shell and a rotating magnetic disk which is hooped on a rotating shaft and uses a hollow magnetic disc as a matrix, wherein the fixed magnet generates opposite-attracting direct magnetic forceto the different-magnetism rotating magnetic disc below the fixed magnet so that the rotating shaft bears controllable supporting force absorbing and pulling upwards to balance the total weight of therotating shaft and reduce the radial bearing pressure of a mechanical bearing; besides, the fixed magnet and the rotating magnetic disk are in a transverse axial magnetic pole coupling state, and thecrytic magnetic coupling force endows the rotating shaft with the supporting rigidity capable of resisting axial displacements to reduce unordered pressure to the mechanical bearing caused by the push of irregular wind force, so the bearing pressure burdens in all directions of the mechanical bearing are significantly reduced, the friction force, the loss and the abrasion in the mechanical bearing are effectively reduced, the power generation efficiency is improved, the running performance is improved, and the service life is prolonged. The magnetic structure is simple, easy, efficient, reliable and practical.
