Description
Technical field
The utility model relates to a kind of flywheel hubs for energy storage device of magnetic suspension flywheel.
Background technique
Flywheel energy storage system breaches the limitation of chemical cell, realizes energy storage with physical method；It utilizes energy converting means
It sets and mutually converts electric energy with mechanical energy, motor drives flywheel rotation, by mechanical energy storage in fly wheel system, and when outside
When load needs electric energy, the flywheel in system drives electrical power generators, converts mechanical energy into electric energy, is converted by power electronics
Electric energy needed for device output loading；Existing flywheel structure is directly installed in shaft mostly, and shaft is as slim-lined construction,
Effective support can not be generated to high-speed rotating flywheel, will lead to shaft and flywheel is unstable in the operating condition；It is existing
Method be by the way that dynamic balancing technics disk is arranged in shaft, but dynamic balancing technics disk and flywheel need to be separately positioned on the two of shaft
End constrains the position of flywheel, and influences the installation of permanent magnet array.
Utility model content
The utility model aim is for overcome the deficiencies in the prior art and provides a kind of for magnetically levitated flywheel energy storage dress
The flywheel hub set.
In order to achieve the above objectives, the technical solution adopted in the utility model is: one kind being used for energy storage device of magnetic suspension flywheel
Flywheel hub, include discoid upper wheel hub and lower hub；Multiple permanent magnetism battle arrays are provided on the uper side surface of the upper wheel hub
Slot allocation is equipped, multiple permanent magnet array fitting grooves are uniformly arranged around the axis of upper wheel hub；Flywheel is provided on the downside of the upper wheel hub
Annular groove is assembled, flywheel mounting ring slot position is in the outer ring of upper wheel hub, and the inner ring of flywheel assembly annular groove is provided with multiple lock slots, more
A lock slots are uniformly arranged around the axis of upper wheel hub；The upper wheel hub is provided centrally with shaft matching hole, shaft matching hole
Multiple axle key mating grooves are provided on side wall, multiple axle key mating grooves are uniformly arranged around the axis of upper wheel hub；The lower hub with
The structure of upper wheel hub is identical, and symmetrically.
Preferably, the upper wheel hub and the outside round edge of lower hub carry out chamfered.
Preferably, the upper wheel hub and lower hub, which cooperate, clamps flywheel, and is fastened by bolts, and bolt head is sunk to
In wheel hub or the permanent magnet array fitting groove of lower hub.
Due to the application of the above technical scheme, the utility model has the advantage that compared with prior art
Flywheel is indirectly attached in shaft by the utility model by the way that upper wheel hub and lower hub is arranged, and upper lower hub can
So that the working condition of flywheel is more stable；And permanent magnet array is mounted in lower hub, reduces the shadow generated to flywheel operation
It rings；Overall structure is simply firm, and is easily installed and later maintenance.
Detailed description of the invention
Technical solutions of the utility model are described further with reference to the accompanying drawing:
Attached drawing 1 is a kind of schematic diagram of the flywheel hub for energy storage device of magnetic suspension flywheel described in the utility model.
Specific embodiment
With reference to the accompanying drawing and specific embodiment the utility model is described in further detail.
As shown in Figure 1, a kind of flywheel hub for energy storage device of magnetic suspension flywheel described in the utility model, includes circle
The upper wheel hub 1 and lower hub 2 of plate-like, upper wheel hub 1 is identical as the structure of lower hub 2, and symmetrically；The upper wheel hub 1 it is upper
Multiple permanent magnet array fitting grooves 4 are provided on side surface, multiple permanent magnet array fitting grooves 4 are uniformly arranged around the axis of upper wheel hub 1,
Permanent magnet array fitting groove 4 can be installed for installing Halbach type permanent magnet array, permanent magnet by adhesion or other modes；
The downside of the upper wheel hub 1 is provided with flywheel assembly annular groove 5, and flywheel assembly annular groove 5 is located at the outer ring of upper wheel hub 1, and flywheel fills
Inner ring with annular groove 5 is provided with multiple lock slots 6, and multiple lock slots 6 are uniformly arranged around the axis of upper wheel hub 1；The upper wheel hub 1
Be provided centrally with shaft matching hole 7, be provided with multiple axle key mating grooves 8 on the side wall of shaft matching hole 7, multiple axle keys cooperations
Slot 8 is uniformly arranged around the axis of upper wheel hub 1, the general uniform setting 3 of axle key mating groove 8, to guarantee optimum stabilization；Upper wheel
Hub 1 and the outside round edge of lower hub 2 carry out chamfered, to reduce assembly collsion damage.
When installation, upper wheel hub 1, lower hub 2 and flywheel 3 are set in shaft, the axle key of upper wheel hub 1 and lower hub 2 is matched
Close slot 8 and shaft to cooperate, and fixed by other such as bolt fixed structures, flywheel 3 between upper wheel hub 1 and lower hub 2,
Upper wheel hub 1 and lower hub 2, which cooperate, clamps flywheel 3, cooperates the inner ring of flywheel 3 and flywheel assembly annular groove 5, and make flywheel
Position and lock toothing enters lock slots 6, then by bolt that upper wheel hub 1, lower hub 2 and flywheel 3 is relatively fixed, can be to avoid
Flywheel 3 relatively rotates with wheel hub, and bolt head is sunk in wheel hub 1 or the permanent magnet array fitting groove 4 of lower hub 2, to save
The space of mounting structure.
The above is only the specific application examples of the utility model, do not constitute any limit to the protection scope of the utility model
System.Any technical scheme formed by adopting equivalent transformation or equivalent replacement, all fall within the utility model rights protection scope it
It is interior.
