Abstract
The invention discloses an energy storing device of a web-type flywheel. The energy storing device comprises a shell, a stator arranged in the middle of the shell and rotors at two sides of the stator, wherein the centers of the rotors at the two sides of the stator are respectively provided with a through hole; the two rotors are fixedly connected by virtue of a complete revolving shaft; and two ends of the revolving shaft support the upper cover plate and lower cover plate of the shell by virtue of bearings. The energy storing device is convenient to process and simple in assembly and maintenance, can be used for achieving a preferable dynamic balance effect, reducing the noises of equipment in running and decreasing the power consumption.
Description
Technical field
The present invention relates to flywheel energy storage system, especially relate to a kind of axiality height, the little web-type flywheel energy storage device of running vibrations.
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 mechanical energy is converted to electric energy.Flywheel energy storage system has multiple method for designing according to different requirements.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 form 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 fixedly connected solid overall structure 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 invention provides a kind of axiality height, the little web-type flywheel energy storage device of running vibrations.
The web-type flywheel energy storage device that the present invention 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 that two rotors are 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 described 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 described shell.
Wherein, described rotor can be a kind of that key connection, spline connect, are threaded or interference fit connects with being connected of rotating shaft.
The present invention 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
The present invention is described in detail below in conjunction with embodiment and accompanying drawing, wherein:
Fig. 1 is the cut-away illustration of preferred embodiment of the present invention.
Embodiment
As shown in Figure 1, the web-type flywheel energy storage device that the present invention 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 it is 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 described 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 as, 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 present invention 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 only is preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of being done within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
