For example, there is JP-A-60-141144. This flywheel power supply device will be described with reference to FIG. The flywheel A is a top type and has a rotating shaft B extending vertically through the center. The rotating shaft B is rotatably supported by upper and lower bearings D and E provided on a casing C. The flywheel A has a circular recess F formed around the rotation axis B on the lower side, and a permanent magnet R is disposed on the inner peripheral surface of the circular recess F. On the other hand, on the bottom wall H of the casing C, a stator J is installed in the circular recess F of the flywheel A so as to face the permanent magnet R. This stator J has a combination structure of an iron core K and a coil L. The inside of the casing C is kept at a high vacuum by the action of the getter M.

いた。At present, the mainstream of measures against momentary power failure caused by lightning strikes or the like is a battery-type power supply device. However, battery-type power supplies use toxic substances that are difficult to dispose of, and environmental pollution will become a serious problem in the near future. On the other hand, since the flywheel power supply device has a structure in which metal parts are mechanically combined, each part can be melted and recycled if its life is over, and disposal after use is extremely easy. Therefore, it was expected that the flywheel power supply device would replace the battery type power supply device as the mainstream of measures against momentary power failure.

ければならないから非常に厄介である。[0005] Contrary to many expectations, however, the penetration rate of flywheel power supplies has been sluggish. The cause may be that it is more expensive than the battery type, but it is also considered that the installation conditions of the flywheel power supply device are severe. In other words, if the installation location is not strictly horizontal, the flywheel will cause precession movement (movement in which the upper end of the rotating shaft swings while drawing an arc around the rotation fulcrum at the lower end of the rotating shaft) according to the principle of top music, and the rotational resistance will increase. As a result, the performance is significantly reduced. Therefore, there is an annoyance that a careful leveling operation must be performed when installing. Such leveling work is very troublesome because it must be performed every time the flywheel power supply device is maintained or moved.

がない。In addition, in connection with the above, the conventional flywheel power supply has a serious problem as an emergency power supply because it is vulnerable to roll. That is, since the precession occurs when the rotation axis of the flywheel is tilted as described above, if the rotation axis is tilted due to a rolling motion such as an earthquake, the performance immediately deteriorates, and it becomes unusable at a practical level. The flywheel power supply is also expected to be used as an emergency auxiliary power supply for an elevator, for example, but is not useful as an auxiliary power supply if it becomes unusable upon occurrence of an earthquake.

In a flywheel power supply device that converts electric energy to kinetic energy by rotating at high speed and stores it, and converts flywheel kinetic energy back to electric energy when necessary, the rotational fulcrum at the lower end of the rotating shaft and the position of the center of gravity And to provide a flywheel power supply device in which the balance of the flywheel is set so as to match.

Is always zero. The precession of the flywheel is caused by the difference in the horizontal distance between the position of the center of gravity of the flywheel and the rotation fulcrum at the lower end of the rotation shaft when the rotation axis is inclined with respect to the vertical line. If is zero, precession does not occur.
Therefore, the leveling work for installing the flywheel power supply device is not required. Also, since the precession does not occur even if the rotation axis is tilted, it is much stronger against rolling, and operates reliably even in an emergency such as an earthquake.

回転抵抗が大きくなるのである。The pivot bearing 5 includes a flywheel 2
This is a known rotary fulcrum, in which the lower end of the rotary shaft 8 is slightly floated with lubricating oil. As shown in FIG. 2, the touch-down bearing 7 has a concave receiving hole 10 formed in an upper part of the flywheel 2, a rotatable short shaft 11 provided in the casing 1, and a short shaft 11 of the casing 1.
Is a so-called eversion type touch-down bearing D (see FIG. 3), which is a so-called eversion type in which the ball is loosely fitted in the receiving hole 10 of the flywheel 2.
The relationship between the shaft and the receiving hole is reversed. By making the touch-down bearing 7 an eversion type, the rotational resistance of the flywheel 2 can be reduced. That is,
When the upper portion of the flywheel 2 swings and the receiving hole 10 comes into contact with the short axis 11, a force acts on the flywheel 2 in a direction in which the receiving hole 10 is separated from the short axis 11. Therefore, the contact pressure can be reduced, and the contact returns to the normal non-contact state immediately. On the other hand, in the conventional add-in type touch-down bearing D, the direction of action of the force is opposite to that of the add-on type touch-down bearing 7, so that the rotary shaft B on the flywheel A side (see FIG. The receiving hole N on the casing C side (FIG. 3)
Contact), a force for maintaining the state is applied, and it is difficult to return to the normal non-contact state, and the rotational resistance increases accordingly.

装置をコンパクトにすることができる。The stator 4 has a combined structure of an iron core 13 and a coil 14 provided around a central base 12, and the pivot bearing 5 is located substantially at the center of the base 12. A getter 15 for maintaining the inside of the casing 1 at a high vacuum is provided at the lower center of the base 12.
A hemispherical cover body 16 surrounding 5 is provided. The cover 16 has an inner peripheral surface that is plated to function as a reflector, thereby preventing heat radiation to the outside. By doing so, it is easy to maintain the getter 15 at about 450 ° C., and the energy saving effect is enhanced. Further, since no heat is radiated to the outside of the cover body 16, even if the getter 15 is arranged near the pivot bearing 5, there is no possibility that the lubricating oil is adversely affected. Since the flywheel 2 and the getter 15 do not need to be separated, the flywheel power supply device can be made compact.

Is provided on the inner periphery of the circular concave portion 9. The balance of the flywheel 2 is set such that the center of gravity G is located at the rotation fulcrum (pivot bearing 5) at the lower end of the rotation shaft 8 with the cage rotor 19 provided.

When a voltage is applied to the flywheel 2, a rotational force acts on the cage rotor 19 based on the same principle as that of the electric motor, and the flywheel 2
It rotates at a high speed of 000 rpm, and electrical energy is converted into kinetic energy and stored. Then, when the power supply to the coil 14 is interrupted due to a power failure or the like, the kinetic energy of the flywheel 2 is converted again into electric energy and supplied to an external load according to the same principle as that of the generator. When a voltage is again applied to the coil 14 of the stator 4 from an external power supply, the flywheel 2 returns to the high-speed rotation state, returning to the principle of the electric motor.

い。Thus, the flywheel power supply device of the present invention is such that the balance of the flywheel 2 is set so that the center of gravity G is located on the rotation fulcrum (pivot bearing 5) at the lower end of the rotating shaft 8. Even if the rotating shaft 8 is inclined with respect to the vertical line in the installed state, the difference in the horizontal distance between the center of gravity G of the flywheel 2 and the rotation fulcrum is zero. Flywheel 2
Is caused by the difference in the horizontal distance between the center of gravity G of the flywheel 2 and the rotation fulcrum at the lower end of the rotating shaft 8 when the rotating shaft 8 is inclined with respect to the vertical line.
If the difference between the horizontal distances does not exist, precession does not occur.

This damper 20 has a structure in which a copper ring 22 is fitted on the inner and outer peripheries of a donut-shaped ferrite magnet 21.
If the flywheel 2 starts slightly oscillating about the center of gravity G, the magnetic lines of force emitted from the upper ferrite magnet 21 intersect with the copper ring 22 to generate an eddy current in the copper ring 22, and the eddy current causes The generated force acts in a direction to suppress the vibration of the flywheel 2.

な効果がある。As described above, in the flywheel power supply device of the present invention, the balance of the flywheel is set such that the rotation fulcrum at the lower end of the rotation shaft coincides with the center of gravity, so that the rotation shaft is inclined with respect to the vertical line. However, the difference in the horizontal distance between the position of the center of gravity of the flywheel and the rotation fulcrum is always zero, and harmful precession of the flywheel hardly occurs. Therefore, leveling work for installing the flywheel power supply device is not required, and new installation and equipment movement can be easily performed. In addition, since precession does not occur, rolling becomes much stronger, and it operates reliably even in an emergency such as an earthquake,
For example, there is a sufficient effect to promote the spread of the flywheel power supply device.
