Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for generating a rotational force by utilizing a magnetic force of a magnet.

[0002]

2. Description of the Related Art If a stable rotating force can be generated by utilizing a magnetic force of a magnet, there is a possibility that a driving source which does not generate heat or noise during operation, is safe to handle, and is excellent in running cost can be obtained.

[0003] Conventionally, the applicant of the present invention has previously proposed, as a device for generating a rotational force using magnetic force, Japanese Utility Model Application No. 62-327852.
There is one proposed by the issue. In this device, one of the facing surfaces of the rotating disk and the fixed disk formed with the same magnetic pole surface is formed as an inclined surface, and the magnetic repulsive force acting between both disks is different due to the difference in distance caused by the inclination. The rotational torque is obtained by the difference in the repulsive force.

[0004]

By the way, in the proposed device, the rotational force is obtained by utilizing the strength of the magnetic repulsive force due to the difference in the distance between the same magnetic poles. Since it acts in the direction, the repulsive force serves as a force for generating the rotational torque, and at the same time, acts as a braking force for stopping the rotation.

Therefore, in order to obtain a stable rotational driving force with the above device, it is necessary to delicately control the shape of the inclined surface of the magnetic pole surface and the strength of the magnetic force of the magnet. Will be a difficult task.

As described above, in order to obtain the rotational force by utilizing the magnetic force, a structure for controlling the direction of the force exerted by the magnetic force on the rotating body to suppress the action of the braking force as much as possible is required. ..

Therefore, the present invention provides an apparatus capable of generating a stable rotational force by suppressing as much as possible the braking force from the magnetic repulsive force of the magnet and effectively extracting only the rotational force starting force. It is the one we are trying to provide.

[0008]

In order to solve the above-mentioned problems, the present invention, as shown in FIG.
A pair of magnet groups 6 and 7 formed by annularly arranging 9, 10 and 11 are arranged with the side surfaces of the magnets 8 and 10 facing each other in parallel, and the one magnet group 7 is arranged on the side surface of each magnet. The surfaces of the magnets 8 and 10 in each of the magnet groups facing the other magnet group are magnetized to the same magnetic pole while being supported by the vertical rotating shaft 4, and the surfaces of the surfaces of the magnets 8 and 10 facing each other are described above. It is divided into two in the rotation direction of the rotary shaft 4, and one of the divided surface layers 12 and 12 'is formed by a magnet layer integrated with each magnet, and the other surface layer 13 and 13' is formed in parallel with the side surface of each magnet. The structure is formed by a magnet layer having magnetic poles in a direction orthogonal to the rotation direction.

In the above structure, an accelerating magnet magnetized to the same magnetic pole as the facing surface of each magnet may be arranged near each magnet in one magnet group.

[0010]

In the above structure, as shown in FIGS. 5 and 6, the magnetic lines a and a'of the magnets 8 and 9 and the magnets 10 and 11 are formed.
Penetrates the surface layers 12 and 12 'in the vertical direction and draws a loop around the outside of the side surface, but the surface layers 13 and 13' are bent in the horizontal direction to prevent them from jumping up and down.

As a result, the lines of magnetic force a, a'exposed from the surface layers 12, 12 'have a vector c directed in the direction of rotation as the sum of the vectors acting on other magnetism,
Rotational torque is applied to the magnet group 7 by the magnetic repulsive force generated between the surface layers 12, 12 ′ of the magnets 8, 10.

At the positions of the surface layers 13 and 13 ', since no magnetic force acts, the braking force for rotation does not act, and the magnet group 7 rotates by inertia.

[0013]

The fixed plate 2 and the rotary plate 3 are made of a ferromagnetic material, and annular magnet groups 6 and 7 are attached to the surfaces thereof. As shown in FIGS. 1 to 4, each of the magnet groups 6 and 7 has a plurality of magnets 8, 9 and 10, 11 arranged annularly symmetrically on the upper and lower surfaces of the fixed plate 2 and the rotary plate 3, respectively. The magnets 8 and 9 and the magnet 1 are formed as follows.

In this case, since the fixed plate 2 and the rotary plate 3 are made of a ferromagnetic material, the central portions of the fixed plate 2 and the rotary plate 3 become nonmagnetic boundary portions 23, 24, and the magnetic force lines a,
As shown in FIGS. 5 and 6 (a), a'is a shape in which the fixed plate and the rotary plate are penetrated at a right angle, and the tip surfaces 8a, 10 of the magnets 8, 10 are a '.
It is formed from a toward the tip surfaces of the magnets 9 and 11.

The surface layers of the tip surfaces of the magnets 8 and 10 have two surface layers 12 and 13 in the rotation direction of the rotating shaft 4.
And 12 ', 13'. In this case, the surface layer 12 on the rotation direction side of the magnet 8 on the fixed plate 2 side,
The surface layer 12 ′ of the magnet 10 on the side of the rotating plate 3 on the side opposite to the rotating direction is formed of a magnet layer integrated with each of the magnets 8 and 10. On the other hand, the surface layers 13 and 13 'adjacent to the surface layers 12 and 12' have the respective magnets 8 and 10 respectively.

The surface layers 13 and 13 ′ are formed, for example, by bonding thin permanent magnets having an N pole and an S pole at the ends in the horizontal direction to the magnets 8 and 10.

In the magnet groups 6 and 7 having the above structure, the magnetic lines of force a and a'of the magnets 8 and 9 and the magnets 10 and 11 are obtained.
On the surface layers 12 and 12 ′ extend in the vertical direction without interference, and draw a loop so as to wrap around the end surfaces of the magnets 8 and 10 and the outsides of both side surfaces. On the other hand, in the surface layers 13 and 13 ',
It is bent in the horizontal direction by the magnetic lines of force of the surface layers 13 and 13 ′, and hardly protrudes in the vertical direction. In this case, the magnetic forces of the magnets 8 and 9 and the magnets 10 and 11 are
By setting the magnetic force much larger than the magnetic force of each surface layer 13, 13 ', as shown in FIG.
Magnetic field lines b extending from 13 'in the horizontal direction are forcibly bent downward or upward, and the magnets 8 and 10 facing each other.
It is possible to almost eliminate the lines of magnetic force that leak up and down from the tip surfaces 8a and 10a.

Therefore, the tip surfaces 8 of the magnets 8 and 10 are
A magnetic repulsion force due to the same magnetic pole (N poles) is generated between the surface layers 12 and 12 'of a and 10a.
A magnetic repulsive force hardly occurs between 3 and 13 ', and no force acts on the rotary plate 3.

The surface layers 12, 1 of the magnets 8 and 10 are also
2'is in the direction opposite to the rotation direction of the rotation shaft 4, and in addition, the magnetic field lines a, a'exiting from the respective surface layers 12, 12 '.

When the 2's face each other, a rotational torque is applied to the rotary plate 3 by the magnetic repulsive force. On the other hand, the surface layers 12, 1
In the state where 2 ′ and 13, 13 ′ or the surface layers 13 and 13 ′ face each other, no force acts on the rotary plate 3 and the rotary plate 3 rotates in an idle state.

Further, in order to more reliably obtain the rotational torque due to the magnetic repulsion force, in the apparatus of the embodiment, as shown in FIG. 3, the magnets 8 and 9 of the fixed plate 2 are arranged in a predetermined direction in the circumferential direction. The magnets 10 are arranged so as to be inclined at an angle, and the direction of the repulsive force by the surface layer 12 is set so as to be directed in the tangential direction of the rotation locus of the magnet 10 on the rotating plate 3 side.

On the other hand, as shown in FIGS. 2 and 3, an accelerating magnet 14 is arranged between the magnets 8 of the fixed plate 2. The accelerating magnet 14 has substantially the same shape as the magnet 8 and has a front end surface 1 of the magnet facing the rotating plate 3.
4a is magnetized to the N pole.

As shown in FIG. 6B, the accelerating magnet 14 is rotated by a magnetic repulsive force on the magnet 10 on the side of the rotating plate 3 to which a rotational torque is applied by the driving magnet 8 due to a magnetic repulsive force (vector). d) is given, and acts to accelerate toward the next driving magnet 8.

The tip end surface 14a of the accelerating magnet 14 is formed to be slightly higher than each magnet 8 and the distance to the magnet 10 on the rotating plate 3 side is set to be the same as each magnet 8 due to the difference in height. As a result, the accelerating magnet 14 can exert a magnetic repulsive force equivalent to that of each magnet 8 on the magnet 10 on the rotating plate 3 side, and smooth and powerful rotational force acceleration can be performed.

This embodiment has a structure as described above,
In a normal state, the rotary plate 3 is lifted up by the repulsive force of the magnets 8 and 10, and the upper end of the rotary shaft 4 is pressed against the pressing plate 20 of the lifting mechanism 5.

From this state, the rotating shaft 4 is moved by the lifting mechanism 5.
When the magnet 8 and the magnet 10 are moved closer to the fixed plate 2 by a predetermined amount, the rotary plate 3 starts to rotate due to the rotational torque generated by the magnetic repulsive force between the magnet 8 and the magnet 10.

The rotating plate 3 thus started to rotate is accelerated by the magnet 8 and the magnet 10 in order, and the rotating torque is applied by the accelerating magnet 14, so that a continuous rotating state is maintained.

In addition to the surface layer 12 of each magnet 8 and the accelerating magnet 14, no force acts to stop the movement of the rotary plate 3 from other portions, so the movement of the rotary plate 3 is braked. No force is applied, and the rotary plate 3 rotates stably and smoothly.

The accelerating magnet 14 is the same as the rotating plate 3
May be provided on the side of, and may be provided on both the rotary plate 3 and the fixed plate 2.

Further, in the structure of the embodiment shown in FIG.
