Description
Technical field: magnetics, magnetic suspension, wind-driven generator
Technology back of the body border:
Vertical axis aerogenerator has its advantage, but the axial load of two mechanical bearings in interior is inhomogeneous and radially also will be subjected to the pushing tow and the twisting of wind-force, wearing and tearing greatly, the life-span is very short, this drawback becomes the bottleneck of development! Solution is the magnetic suspension bearing of wiping with no mould, the electromagnetic bearing of the U.S., and too complicated, cost is high, can only be experiment product; Patent: in 20061012279.4, complexity and cost height; Patent: adopt among the 200710099004.X whole on carry Noboru magnetic bearing make a concerted effort, need add axial limit stoper.
Summary of the invention:
Goal of the invention: adopt the magnetic suspension bearing of the axis wind power generator that is suitable for standing, efficient and simple structure, cost is not high, and debugging is convenient, and the cost performance ideal is easy to go into operation.
Technological scheme:
The structure of the combination of the face-off magnetic type of employing magnetic suspension bearing, specific as follows:
The concrete structure of the combination of the face-off magnetic type of magnetic suspension bearing, for; Magnetic suspension bearing is enclosed within the axle disk on the axle that stands by hoop and the corresponding shell disk that is installed in the shell is formed disk: a disk and shell disk, all constitute by at least one magnet ring, disk and magnet ring all be coaxial all be axial magnetic in a And that stands; Have at least two covers to produce the magnetic suspension bearing of axial face-off magnetic force in the combination: a cover imposes on solid of rotation with axial downward magnetic force, another set ofly apply the bigger magnetic force that makes progress, the difference of upwards and downward magnetic force is as to the supporting force of solid of rotation in the weight of longitudinal balance solid of rotation; Magnetic suspension bearing in the combination comprises: suction type magnetic suspension bearing and scold the type magnetic suspension bearing; Scold the axle disk of type magnetic suspension bearing and axially repel each other with the shell disk of magnetic, the axle disk of suction type magnetic suspension bearing and the shell disk of different magnetic, outside axially inhaling mutually, also be in magnetic pole coupled state radially, imply and give the bonding force that solid of rotation has the support stiffness of radial location effect; Combination can with can play the location and the mechanical bearing of protective action, use complementally.
When being adjusted to that axial supporting makes a concerted effort to equal or when approaching very much the weight of solid of rotation, solid of rotation is in axial: magnetic suspension or accurate magnetcisuspension floading condition, then, solid of rotation is eliminated or slowly-releasing and Reduction of Students' Study Load the axial pressure of mechanical bearing and the axial load of mechanical bearing, makes the axial friction of mechanical bearing and wearing and tearing also correspondingly eliminate or reduce effectively.
The effect of the magnetic pole coupled state radially of suction type magnetic suspension bearing and the bonding force that has is: under the pushing tow of the solid of rotation that is connected with fan blade at irregular wind-force, also correspondingly can produce radially displacement and angle distortion between the axle disk of described suction type magnetic suspension bearing and the shell disk, mechanical bearing also can be subjected to corresponding radial force and oblique lateral force, at this moment, the magnetic pole coupled state inspires reverse bonding force, can resist above-mentioned Ying Xiang And effectively and give solid of rotation with support stiffness, mechanical bearing can radially eliminated or slowly-releasing with the load of side direction, the radially and tiltedly Side that has reduced mechanical bearing to friction and wearing and tearing.
Solid of rotation is: the interior rotatable axle that stands that fan blade and rotor and hoop are with the rotation of a disk that is connected with, that is: and rotating shaft, an axle disk rotates with rotating shaft; The shell disk is contained in the fixing shell that is connected with stator: decide in the shell: the axial supporting force ， And that rotating shaft has been subjected to combination has the support stiffness of being given by suction type magnetic suspension bearing radially; Solid of rotation is if being connected with fan blade and rotor and the shell of the rotation of shell disk is housed of outward rotation type, that is: transcapsidation, and the shell disk rotates with transcapsidation, and axle disk hoop is enclosed within the fixing axle that stands that is connected with stator: on the dead axle; Axially mounting power that transcapsidation is made up and quilt have been given support stiffness radially.
The structure of disk is the magnet ring that is pasted with the different rings footpath on coaxial iron pan face, and distance is all arranged out between adjacent magnet ring, and each magnet ring of axle disk is corresponding with each shell magnet ring of corresponding shell disk respectively.
Adopt: the combination of dual-sucking type, rotating shaft or transcapsidation have been subjected to synthetic supporting force and support stiffness, can economize with a mechanical bearing, use originally in the shell of two mechanical bearings, can be with one.
As be combined as: inhale and scold type: suction type magnetic suspension bearing and the axially mounting power of scolding the type magnetic suspension bearing to synthesize, and radial support rigidity is provided by suction type magnetic suspension bearing, and this combination also can economize with a mechanical bearing. twoly scold type: two covers are scolded the type magnetic bearing structure; Two axially synthetic to repulsion supporting forces make rotating shaft or transcapsidation, if be positioned axial magnetcisuspension floading condition. and adopt: two composite structures: use simultaneously: twoly scold type and dual-sucking type; Form axial respectively and magnetic suspension radially; Then, two mechanical bearings in the shell can all exempt to use.
Beneficial effect:
The structure of the combination of face-off magnetic type, the regulation range of axial supporting force is strengthened, because of the axial magnetic suction demand support stiffness greatly radially to suction type magnetic suspension bearing heightens, the actual utility of magnetic suspension bearing is increased, with to local or replace mechanical bearing fully, that is: the desirable target of magnetic suspension bearingization provides alternative plan.
