Abstract
The utility model relates to a vertical axis windmill with a magnetic suspension mechanism. The vertical axis windmill comprises a windmill body and a generator. The vertical axis windmill is characterized in that stator iron cores and windings are relatively arranged on an upper supporting plate and a lower supporting plate of a shell; a permanent magnetic rotor consists of a supporting disc made of a magnetic conductive material and a permanent magnet; the supporting disc is fixedly connected with a vertical axis; the permanent magnet is arranged on the supporting disc; the permanent magnet is positioned between two stator iron cores; and the permanent magnet and the stator iron cores fixed on the upper supporting plate and the lower supporting plate respectively form an upper air gap and a lower air gap with different clearance. With the structure, an additional magnetic pull force is produced between the upper air gap and the lower air gap to overcome the axial force born by a bearing, reduce the abrasion of the bearing and prolong the service life of the bearing; at the same time, the vertical axis windmill reduces the frictional force of the bearing and improves the mechanical efficiency. Therefore, the vertical axis windmill can not only effectively overcome the axial force born by the bearing, reduce the abrasion of the bearing and prolong the service life of the bearing but also improve the mechanical efficiency.

Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, a kind of vertical axis windmill that installs magnetic suspension system, comprise windmill body (not drawing among the figure) and generator, described windmill body is installed on the load-bearing flange 14 of generator, described generator comprises casing 1, vertical axis 2, bearing 3, p-m rotor 5, stator core 4 and winding, the supporting disk 51 that p-m rotor 5 is made by permeability magnetic material, the permanent magnet 52 that is installed on the supporting disk 51 constitutes, described casing 1 is by last, on the following layout, lower supporting plate 11,12, be positioned at, lower supporting plate 11, coaming plate 13 between 12 constitutes, casing 1 is installed on the supporting base 15 on windmill vertical rod or ground, vertical axis 2 upper ends are fixed with load-bearing flange 14, and the windmill body is installed on the load-bearing flange 14.
On the upper and lower supporting bracket 11,12 of casing 1, be relatively set with stator core 4 and winding; Supporting disk 51, permanent magnet 52 that described p-m rotor 5 is made by permeability magnetic material constitute, supporting disk 51 is fixedly connected with vertical axis 2, permanent magnet 52 is installed on the supporting disk 51, and permanent magnet 52 is between two stator cores 4, and is gapped between permanent magnet 52 and two stator cores 4.Permanent magnet 52 and the gap that is fixed between the stator core 4 on the upper backup pad 11 are called air gap 61, and permanent magnet 52 and the gap that is fixed between the stator core 4 on the lower supporting plate 12 are called air gap 62 down.
In the present embodiment, last air gap 61 is less than following air gap 62, and last air gap 61 and following air gap 62 differences produce the additional magnetic pull that makes progress.
When last air gap 61 greater than following air gap 62, last air gap 61 and the 62 difference generations of following air gap add downward magnetic pull, can be used in other plant equipment.
