When two permanent-magnet structures 2 and the 5th permanent-magnet structure 5 move to axial, restricted by while gravitation and repulsion.
As Figure 8-9, those skilled in the art are not difficult to obtain, and there are many forms of static axial direction rock-steady structure, as long as
The position to axial of stator and rotor can be limited.For example, multilayer permanent-magnet component is overlapped, the permanent-magnet component and monopole spoke
Permanent-magnetic clamp characteristics of geomagnetic field distribution having the same is penetrated, the adjacent two layers permanent-magnet component polarity is on the contrary, make 2 He of the second permanent-magnet structure
When 5th permanent-magnet structure 5 moves to axial, equally by gravitation and repulsion while restrict.
In order to make before critical speed in rotor static state and reaching, rotor is in the repulsion of the heart in the stator always and gravitation is flat
Weigh point, and the present embodiment further includes two critical speed clutches for being respectively arranged at connecting shaft both ends.
As shown in figs. 10-12, critical speed clutch includes centrifugal block for clutch use tonicity confinement plate 10, centrifugal block for clutch use 11, fastening
Part, auxiliary bearing 9, reset spring 12 and fixing axle 13.In one end of connecting shaft 7 and the side of centrifugal block for clutch use tonicity confinement plate 10
It is fixedly connected at the heart, the other side of centrifugal block for clutch use tonicity confinement plate 10 has the cricoid wall surface being coaxially disposed with connecting shaft 7.Two
A centrifugal block for clutch use 11 is set on the inside of wall surface and respectively by a fastener and centrifugal block for clutch use tonicity confinement plate 10 and is rotatablely connected, and two
Centrifugal block for clutch use 11 and two fasteners are centrosymmetric setting about the center of centrifugal block for clutch use tonicity confinement plate 10.Centrifugal block for clutch use
11 inside to the detachable connection of auxiliary bearing 9, auxiliary bearing 9 is set in fixing axle 13.Reset spring 12 is arranged
Between auxiliary bearing 9 and centrifugal block for clutch use tonicity confinement plate 10, the both ends of reset spring 12 are individually fixed in two centrifugal block for clutch use
On 11.In the present embodiment, fastener is fixed screw.
When the rotation speed of the critical speed clutch at 7 both ends of rotor and connecting shaft is lower than predetermined value, centrifugal block for clutch use 11
It links together under 12 pulling force effect of reset spring with auxiliary bearing 9, when the critical speed clutch at 7 both ends of rotor and connecting shaft
When the rotation speed of device is at or above predetermined value, centrifugal block for clutch use 11 overcomes 12 pulling force of reset spring and auxiliary bearing 9 to separate.
Critical speed clutch still links together with rotor after separation, until resetting bullet when rotation speed is again below predetermined value
Centrifugal block for clutch use 11 and auxiliary bearing 9 link together again under 12 pulling force effect of spring.
Therefore, before rotor reaches critical speed, the inside of centrifugal block for clutch use 11 and auxiliary bearing 9 are connected, and make to turn
Son is always in the repulsion of the heart and granitational equilibrium point in the stator, and after rotor reaches critical speed, centrifugal block for clutch use 11 is detached from
Auxiliary bearing 9, the rotor of high-speed rotation is provided with gyroscopic effect at this time, and bearing radially has certain bearing capacity and stabilization
