Abstract
The utility model discloses a web type flywheel energy storage device, which comprises a casing, a stator in the middle of the casing and rotors on two sides of the stator. A through hole is arranged in the center of each rotor on two sides of the stator, the two rotors are fixedly connected by an integral rotary shaft, and two ends of the shaft are supported on an upper cover plate and a lower cover plate of the casing through bearings. The web type flywheel energy storage device is convenient in processing and simple in assembly and maintenance, better dynamic balance effect can be obtained, noise in operation of equipment is reduced, and power consumption is reduced.
Description
Technical field
The utility model relates to flywheel energy storage system, especially relates to the web-type flywheel energy storage device that a kind of axiality is high, the running vibrations are little.
Background technology
The flywheel energy storage principle generally is to rely on the rotation of driven by motor flywheel, stores and convert electrical energy into mechanical energy, and when needed, flywheel slows down and converts mechanical energy into electric energy.Flywheel energy storage system has multiple method for designing according to different requirement.Flywheel energy storage system is generally supported by magnetic bearing, particularly in the high speed flywheel energy-storage system.In order to reduce air drag and energy loss, flywheel generally is placed in the vacuum chamber.Disc type high speed flywheel energy-storage system with round trip flight wheel (rotor), single stator; Stator discs is positioned between two flywheels (rotor); Two flywheels middle part is fixedly connected and forms a solid overall structure, and the flywheel both sides form coaxial mounting structure by two axles, and an end of every axle is by bearings.In order to guarantee the vacuum degree of vacuum chamber, axle and bearing all are placed in the vacuum chamber.Flywheel of the prior art adopts the atresia disc structure more, adopts the solid overall structure that is fixedly connected between two flywheels, and two axles are installed by the flywheel both sides, makes the axiality of flywheel be difficult to guarantee, particularly when high speed rotating, is easy to generate than big bang.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides the web-type flywheel energy storage device that a kind of axiality is high, the running vibrations are little.
The web-type flywheel energy storage device that the utility model proposes, it comprises shell, is located at the middle stator of this shell, is located at two rotors of these stator both sides.The rotor center that is positioned at the stator both sides has through hole, and by the rotating shaft of an integral body two rotors is fixedly connected, the rotating shaft two ends by bearings on the upper and lower cover plate of shell.
More excellent.Carry out axial location by the location shoulder that is provided with in a sleeve or the rotating shaft between said two rotors, the outside of rotor is respectively by gland and bearing axial restraint, and the bearings at two ends is on the upper and lower cover plate of said shell.
Wherein, said rotor can be a kind of that key connection, spline connect, are threaded or interference fit connects with being connected of rotating shaft.
The utility model adopts two rotor centers to open the hole, and by the structure of a whole rotating shaft with the fixing fixed connection of two rotors, can guarantee the axiality of rotor and rotating shaft effectively, the vibrations when reducing to turn round.Easy to process, assembling and easy to maintenance, and can obtain better dynamic balancing effect, the noise when reducing equipment operation reduces power consumption.
Description of drawings
Below in conjunction with embodiment and accompanying drawing the utility model is elaborated, wherein:
Fig. 1 is the cut-away illustration of the utility model preferred embodiment.
Embodiment
Web-type flywheel energy storage device as shown in Figure 1, that the utility model proposes comprises shell 1, is located at the middle stator 2 of this shell, is located at the rotor 3 of these stator both sides.Rotor 3 centers that are positioned at the stator both sides have through hole; And two rotors are fixedly connected by a whole rotating shaft 4; Isolate (also can carry out axial location) by a sleeve 5 between two rotors by the location shoulder that is provided with in the rotating shaft; By gland 6 and bearing 7 axial restraints, the bearings at two ends is on the cover plate up and down of the side of said shell 1 respectively in the outside of rotor.Rotor 3 is connected with the key that is connected to of rotating shaft 4, can also adopt the connection of other structures as required, connects, is threaded or interference fit connects or the like like, spline.The axial location of shafting componentses such as rotor 3, stator 2 and rotating shaft 4, be connected, can adopt various prior aries, repeat no more.
The utility model adopts rotor split production, center to have through hole, and by the structure of a whole rotating shaft with the fixing fixed connection of rotor, can guarantee the axiality of rotor and rotating shaft effectively, the vibrations when reducing to turn round.Easy to process, assembling and easy to maintenance, and can obtain better dynamic balancing effect, the noise when reducing equipment operation reduces power consumption.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection range of the utility model.
