Description
Technical field
The invention belongs to technical field of generators, more particularly to a kind of low-speed generator magnetic suspension rotating shaft.
Background technology
The bearing of conventional generator is divided by its function as thrust bearing and journal bearing, is divided into sliding axle by its internal structure
Hold and rolling bearing.In each class bearing, there is problems with, firstly, since mechanical friction causes energy loss；Next to that warm
Degree rise causes bearing damage；3rd be because of fretting wear so that overhaul, change frequently, high speed rotate when can produce it is substantial amounts of
Heat, causes the abrasion of rotor shaft or even deforms upon, have a strong impact on the service life of generator.Current most of generators
The rotating speed of rotating shaft is all more than 500 turns, such as 1500-2800 revs/min of even more high, is to generate electricity under relatively low speed conditions
's.
The content of the invention
Present invention aims at a kind of low-speed generator magnetic suspension rotating shaft is provided, realize compared with just can under the slow-speed of revolution
The effect of generating, to reach that above-mentioned purpose is adopted the technical scheme that：
A kind of magnetic suspension rotating shaft of low-speed generator, including the shaft body vertically set, it is characterised in that in shaft body
On be sequentially coaxially fixed with multiple rotating disks from top to bottom, on rotating disk around shaft body circumferencial direction be embedded with multiple inner magnets,
Multiple outer magnets and multiple activation magnets, the multiple inner magnet are set against shaft body, and outer magnet is located at the outer ring of inner magnet,
Activation magnet is located at the outer ring of outer magnet, and the magnetic pole of the inner magnet and outer magnet is set in the same direction and vertically；By
Magnet segment is equipped with shaft body at nearly disk upper surface and lower surface, the magnetic pole of the magnet segment is each along shaft body radial direction
Direction sets and forms a radial magnetic field around shaft body circumferentially diversity.
It is preferred that, the magnetic pole of the multiple activation magnet is set in the same direction and vertically.
It is preferred that, multiple secondary activation magnets are circumferentially uniformly embedded with the circumference side of rotating disk, it is described many
The magnetic pole of individual secondary activation magnet sets each along rotating disk radial direction and forms a radial direction around rotating disk circumferentially diversity
Magnetic field.
It is preferred that, multiple hollow outs are equipped with rotating disk.
The advantageous effect of present invention is that：Vertical, radial direction two of this rotating shaft are realized by the effect of magnetic field repulsive force
The fixation in individual direction, is a kind of real suspension rotary state.On the other hand, by setting coil respectively up and down in activation magnet
Winding, shaft body drive multiple rotating disks while being set of both generating electricity simultaneously, have reached and also can in the case where rotating speed is relatively low
It is enough to realize the purpose generated electricity.
Brief description of the drawings
Fig. 1 is structural representation of the invention；
Fig. 2 is the structural representation of rotating disk.
Embodiment
The present invention is further described below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, a kind of low-speed generator magnetic suspension rotating shaft, including the shaft body vertically set
