An exemplary arrangement of the plurality of second magnet units 221, 222, 225 and the plurality of third magnet units 221a, 222a, 225a will be described later with reference to FIGS. 8 and 9.

The magnetic gear 321 is installed in the first portion 121. The magnetic gear 321 may be installed on the first portion 121, as shown.

An exemplary configuration of the magnetic gear 321 will be described later with reference to FIGS. 10 to 14.

The first non-rotating body 170 or the second non-rotating body 171 is fixed and may not move. That is, the distance between the first non-rotating body 170 and the second portion 122 and the distance between the second non-rotating body 171 and the third portion 123 may be constant.

Alternatively, depending on the design, the first non-rotating body 170 or the second non-rotating body 171 can move along the extending direction of the shaft 110 (see reference numerals D1 and D2). The movement of the first non-rotating body 170 or the second non-rotating body 171 may be moved through, for example, an actuator using electricity, hydraulic pressure, compressed air, or the like. It can also be moved. As long as the first non-rotating body 170 or the second non-rotating body 171 can be moved, any method can be used.

Specifically, by adjusting the distance between the first non-rotating body 170 and the second portion 122, the plurality of first magnet units 271, 272, 275 and the plurality of second magnet units (221, 222, 225) You can adjust the amount of repulsive force between Similarly, by adjusting the distance between the second non-rotating body 171 and the third portion 123, the plurality of third magnet units 221a, 222a, 225a and the plurality of fourth magnet units 271a, 272a, 275a.

Through the combination of the distance between the first non-rotating body 170 and the second portion 122 and the distance between the second non-rotating body 171 and the third portion 123, the speed of the rotating body 120 is required. It can be controlled in size.

On the other hand, in the first gear component according to some embodiments of the present invention, the first magnet unit 271, 272, 275, the second magnet unit 221, 222, 225 have a first polarity (eg, N pole). ), The third magnet units 221a, 222a and 225a and the fourth magnet units 271a, 272a and 275a have been described as having a second polarity (for example, S pole), but are not limited thereto. That is, a repulsive force is generated between the second portion 122 and the first non-rotating body 170 (that is, between the first magnet units 271, 272, and 275 and the second magnet units 221, 222, and 225). , The repulsive force may be generated between the third portion 123 and the second non-rotating body 171 (that is, between the third magnet units 221a, 222a and 225a and the fourth magnet units 271a, 272a and 275a). If present, the polarity is not limited.

Although not separately shown, a magnetic shield is installed inside and / or outside the first gear component to shield the magnetic force generated inside the first gear component from affecting the outside. .

On the other hand, the shaft 110 may be connected with another rotating shaft (or another gear component), so that the shaft 110 may rotate together with the rotation of the other shaft.

or. The power supply may be electrically connected to the shaft 110. In addition, a control unit for controlling the power supply unit is connected. The power supply unit supplies power to the motor, for example, the shaft 110 rotates according to the rotation of the motor, and the rotating body 120 rotates as the shaft 110 rotates. The power supply may be a battery, but is not limited thereto. By using a battery, the first gear component is easy to move / install and can be easily used anywhere. In addition, as described later, since the battery is not used much, even a battery having a small capacity can be used for a long time.

On the other hand, while the rotating body 120 is rotated, supply / blocking of power for rotating the rotating body 120 may be repeated.

Specifically, the power supply unit supplies power to the motor, and the shaft 110 and the rotating body 120 of the first gear component 100 may be rotated by the motor.

For example, power is provided during a period in which the rotating body 120 rotates at a predetermined rotation speed or a predetermined time, for example, 1000 to 3000 times. When the rotating body 120 rotates at a predetermined rotation speed (after rotating for a predetermined time), power may not be supplied to the rotating body 120 for a predetermined period of time. The "preset period" not supplying power may be a fixed time or may be a time changed according to the rotational speed of the rotating body 120. During a period in which no separate power is supplied, the rotor 120 may continuously rotate using a magnetic field surfing operation. That is, through the magnetic field surf, the rotating body 120 can rotate for a long time (compared to the rotating body not using the magnetic field surfing). The period of no power can be extended.

Magnetic field surfing is a concept similar to wind surfing using ocean waves. When a magnetic distribution wave of a magnet is viewed as a vector, the surfing of a fixed magnetic vector wave is a rotating magnetic vector wave. For example, between the plurality of first magnet units 271, 272, and 275 installed in the first non-rotating body 170, and the plurality of second magnet units 221, 222, and 225 installed in the rotating body 120. Magnetic field surfing can be performed by using the relative phase difference of the generated magnetic field. Similarly, the plurality of fourth magnet units 271a, 272a, and 275a installed in the second non-rotating body 171 and the plurality of third magnet units 221a, 222a, and 225a installed in the rotating body 120 are generated. The magnetic field surfing can be performed by using the relative phase difference of the magnetic field.

In addition, the rotating body 120 is rotated slower than the predetermined speed, or after a predetermined time, the power supply may supply power to the motor again. Accordingly, the rotating body 120 again rotates at a predetermined speed. As such, while the rotating body 120 rotates, the power supply unit may repeat supplying / blocking power. For example, the supply / blocking of power may be repeated according to a specific period. Alternatively, the supply / blocking of power may be repeated aperiodically based on, for example, the speed of the rotating body 120. For example, the degree of rotation of the rotating body 120 may be checked using a speed sensor or the like, and power supply / blocking may be repeated according to the checked result.

On the other hand, if the surfing operation of the rotating body 120 is not desired (or the surfing operation of the desired degree is not performed), try again by adjusting the distance between the rotating body 120 and the non-rotating body (170, 171) can see. This spacing is an important factor in the surfing motion of the rotor 120. As the distance between the rotor 120 and the non-rotators 170 and 171 becomes narrower, the repulsive force becomes stronger. When the distance between the rotating body 120 and the non-rotating members 170 and 171 becomes a specific value, a high speed can be achieved even with a small power supply.

Hereinafter, the first non-rotating body 170 will be described with reference to FIGS. 4 to 7.

FIG. 4 is a view for explaining the first non-rotating body of FIG. 2 and for explaining a surface facing the second part of the rotating body. FIG. 5 is a conceptual diagram for describing a relationship between a plurality of first magnet units installed in the non-rotating body of FIG. 4. 6A, 6B and 7 are conceptual views for explaining the magnetic field of the first magnet unit installed in the first non-rotating member of FIG. 4.

The plurality of first magnet units 271, 272, and 275 may form a plurality of rows L1, L2, and L3 about the axis 110. Thus, for example, the distance from the axis 110 to the first column L1 is closer than the distance from the axis 110 to the second column L2. In FIG. 4, three columns L1, L2, and L3 are illustrated, but the present invention is not limited thereto. The plurality of first magnet units 271, 272, and 275 may have a plurality of rows, for example, four or more rows.

Each of the rows L1, L2, and L3 includes a plurality of first magnet units 271, 272, and 275 spaced apart from each other. In detail, the number of the plurality of first magnet units 271 arranged in the first column L1 may be the same as the number of the plurality of first magnet units 272 arranged in the second column L2. . For example, fourteen first magnet units 271, 272, and 275 may be disposed in each row L1, L2, and L3. Although illustrated as fourteen first magnet units 271, 272, and 275, the present disclosure is not limited thereto. For example, 11 to 24 first magnet units may be arranged.

Meanwhile, although the same number of first magnet units 271, 272, and 275 are disposed in the columns L1, L2, and L3, the present invention is not limited thereto. Depending on the design, a different number of first magnet units 271, 272, 275 may be arranged. For example, since the first row L1 is a row directly in contact with the axis 110, if the space is limited, the number of the first magnet units 271 may be smaller.

In addition, as illustrated in FIG. 4, the intervals W1, W2, and W3 between the plurality of first magnet units 271, 272, and 275 disposed in the columns L1, L2, and L3 may be different from each other. . For example, the interval W2 between the plurality of first magnet units 272 disposed in the second row L2 is between the plurality of first magnet units 271 arranged in the first row L1. It may be wider than the interval W1.

In addition, the first distance P1 between the first column L1 and the second column L2 and the second distance P2 between the second column L2 and the third column L3 may be equal to each other. But it is not limited thereto. According to the design, the first distance P1 and the second distance P2 may be different from each other.

Meanwhile, as shown in FIG. 5, the central axis CL of the first magnet unit 271 of the first row L1 and the central axis CL of the first magnet unit 272 of the second row L2 are shown. ), The central axes CL of the first magnet units 275 of the third row L3 may be parallel to each other. In other words, the first magnet units 271, 272, and 275 in the columns L1, L2, and L3 may be disposed in the same phase. Alternatively, the central axis CL of the first magnet unit 271 of the first row L1, the central axis CL of the first magnet unit 272 of the second row L2, and the third row L3 may be used. The central axis CL of the first magnet unit 275 has a phase difference of zero. Alternatively, the arrangement of the first magnet units 271, 272, and 275 in each of the columns L1, L2, and L3 is different from the arrangement of the second magnet units 221, 222, and 225 in the columns L4, L5, and L6. , May have a first phase difference. For example, the first phase difference may be 0, but is not limited thereto.

In addition, the sizes of the first magnet units 271, 272, and 275 disposed in the rows L1, L2, and L3 may be different from each other. The size of the first magnet unit 272 of the second row L2 may be larger than that of the first magnet unit 271 of the first row L1. The size of the first magnet unit 275 in the third row L3 may be larger than the size of the first magnet unit 272 in the second row L2. In addition, the sizes of the first magnet units 271 disposed in each row (eg, L1) may be the same.

In addition, when two straight lines a1 and a2 are drawn outwardly about the axis 110, the first magnet unit 271 of the first row L1 and the second magnet unit of the second row L2 are drawn. 272, the first magnet unit 275 in the third row L3 may be in contact with the two straight lines a1 and a2. Here, the contact with the two straight lines a1 and a2 means that the side walls of the first magnet units 271, 272 and 275 overlap with the two straight lines a1 and a2. On the other hand, depending on the design, the straight lines a1 and a2 may overlap only part of the sidewalls without overlapping the entire sidewalls of the first magnet units 271, 272 and 275 (see FIG. 18).

On the other hand, the central axis CL of the first magnet units 271, 272, and 275 of the columns L1, L2, and L3 has a phase difference from the magnetic axes MC1, MC2, and MC5. As shown, the central axis CL and the magnetic field axes MC1, MC2, and MC5 may not be parallel to each other.

For example, as illustrated, there may be an angle difference of θ11, θ12, and θ13 between the corresponding central axis CL and the magnetic field axes MC1, MC2, and MC5, respectively. θ11, θ12, and θ13 may be acute angles in a first direction (for example, counterclockwise) with respect to the central axis CL. Meanwhile, the angle differences θ11, θ12, and θ13 between the corresponding central axis CL and the magnetic field axes MC1, MC2, and MC5 may be completely the same. Alternatively, the angle differences θ11, θ12, and θ13 may be different from each other. Alternatively, θ11 and θ12 may be the same as each other, and θ13 may be different from θ11 and θ12. This angle difference can be changed depending on the design.

6A, 6B, and 7, FIG. 6A is a plan view of a first magnet unit (eg, 271). For example, the north pole of the first magnet unit 271 is shown. FIG. 6B shows a magnetic force vector wave in the first magnet unit 271. 6A and 6B, the first magnet unit 271 has an unbalanced arbitrary magnetic field, so that the magnetic force vector waves MV1 to MV5 and MV11 to MV15 of the first magnet unit 271 are unbalanced. to be. For example, the MV1 magnetic vector wave may be the largest at the N pole of the first magnet unit 271, and the MV1 magnetic vector wave may be biased to one side (left side in the drawing). The MV11 magnetic vector wave may be the largest at the S pole of the first magnet unit 271, and the MV11 magnetic vector wave may be biased to the other side (the right side in the drawing).

As shown in FIG. 6A, the magnetic field axis MC1 may be a continuous flow connecting the largest magnetic force vector waves MV1.

On the other hand, the shape of the unbalanced magnetic vector wave is not limited to Figs. 5, 6A, 6B, and 7. For example, in FIG. 5, the central axis CL and the magnetic field axes MC1, MC2, and MC5 cross each other, but are not limited thereto. The central axis CL and the magnetic field axes MC1, MC2, and MC5 may have other shapes as long as they are not parallel to each other (or there is a phase difference). For example, as shown in FIG. 6A, if the first magnet unit 271 is trapezoidal (a trapezoidal shape), the magnetic axis is parallel to the trapezoidal inclined side (left side or right side in FIG. 6A). It may be arranged. That is, the magnetic axis may be formed long along the inclined side.

As shown in FIG. 7, the first magnet unit 271 may have a magnetic field magnetic field in which the N pole and the S pole are not equal. For example, the angle between the north pole and the south pole may be within 45 degrees from 0 degrees, and the force of the magnetic force may be from 3000 gauss to 5000 gauss, but is not limited thereto.

Next, the rotating body 120 is demonstrated using FIG. 8 and FIG.

FIG. 8 is a diagram for describing a second part of the rotating body of FIG. 2. FIG. 9 is a conceptual view for explaining a relationship between a plurality of second magnet units installed in the rotating body of FIG. 8.

8 and 9, a plurality of second magnet units 221, 222, and 225 are disposed in the second portion 122 of the rotating body 120. The plurality of second magnet units 221, 222, and 225 may form a plurality of rows L4, L5, and L6 about the axis 110. Thus, for example, the distance from the axis 110 to the fourth column L4 is closer than the distance from the axis 110 to the fifth column L5. In FIG. 8, three columns L4, L5, and L6 are illustrated, but embodiments are not limited thereto. The plurality of second magnet units 221, 222, and 225 may have a plurality of rows, for example, four or more rows.

The fourth row L4 of the rotor 120 rotates while looking at the first column L1 of the first non-rotator 170, and the fifth column L5 of the rotor 120 is the first non-rotator ( Looking at the second row (L2) of 170 is rotated. The sixth row L6 of the rotating body 120 rotates when looking at the third row L3 of the first non-rotating body 170.

In each row L4, L5, and L6, a plurality of second magnet units 221, 222, and 225 spaced apart from each other are disposed. In detail, the number of the plurality of second magnet units 221 arranged in the fourth row L4 may be the same as the number of the plurality of second magnet units 222 arranged in the fifth row L5. . Thirteen second magnet units 221 are disposed in the fourth row L4, and thirteen second magnet units 222 are disposed in the fifth row L5. For example, eleven to twenty-four second magnet units 221, 222, and 225 may be disposed in the fourth row L4 and the fifth row L5.

Meanwhile, although the same number of second magnet units 221, 222, and 225 are disposed in the rows L4, L5, and L6, the present invention is not limited thereto. Depending on the design, different numbers of second magnet units 221, 222, 225 may be arranged. For example, since the fourth row L4 is a row directly in contact with the axis 110, if the space is limited, the number of the second magnet units 221 may be smaller.

As described above, the fourth column L4, the fifth column L5, and the sixth column L6 face the first column L1, the second column L2, and the third column L3, respectively. Rotate However, the number of the plurality of first magnet units 271 arranged in the first column L1 and the number of the plurality of second magnet units 221 arranged in the fourth column L4 are different from each other. Similarly, the number of the plurality of first magnet units 272 disposed in the second row L2 and the number of the plurality of second magnet units 222 disposed in the fifth row L5 may be different from each other.

In addition, the interval W4 between the plurality of second magnet units 221 arranged in the fourth row L4 is equal to the interval between the plurality of second magnet units 222 arranged in the fifth row L5. Narrower than W5). Similarly, the spacing W5 between the plurality of second magnet units 222 arranged in the fifth row L5 is the spacing between the plurality of second magnet units 225 disposed in the sixth row L6. Narrower than W6).

In addition, the third distance P3 between the fourth column L4 and the fifth column L5 and the fourth distance P4 between the fifth column L5 and the sixth column L6 may be equal to each other. But it is not limited thereto. According to the design, the first distance P3 and the second distance P4 may be different from each other.

The size of the second magnet unit 222 of the fifth row L5 may be larger than that of the second magnet unit 221 of the fourth row L4. The size of the second magnet unit 225 of the sixth row L6 may be larger than that of the second magnet unit 222 of the fifth row L5.

As shown in FIG. 9, the center axis CL3 of the second magnet unit 221 in the fourth row L4 and the center axis CL4 of the second magnet unit 222 in the fifth row L5. Are not parallel to each other (ie, there is a phase difference). In detail, the second magnet unit 222 of the fifth column L5 may be disposed at a rear side with a phase difference from the second magnet unit 221 of the fourth column L4. The second magnet unit 225 of the sixth row L6 may be disposed at a rear side with a phase difference from the second magnet unit 222 of the fifth row L5. Alternatively, the arrangement of the second magnet units 221, 222, and 225 in the columns L4, L5, and L6 is different from the arrangement of the first magnet units 271, 272, and 275 in the columns L1, L2, and L3. , May have a second phase difference. For example, the second phase difference may be a non-zero value. For example, the straight line a3 that faces outward about the axis and contacts the second magnet unit 222 of the fifth row L5 is the second magnet unit 221 or the sixth row of the fourth row L4. It may not be in contact with the second magnet unit 225 of (L6). Depending on the design, the straight line a3 may overlap only part of the sidewalls without overlapping the entire sidewall of the second magnet unit 222 (see FIG. 20).

The central axes CL3, CL4, CL6 of the second magnet units 221, 222, 225 of each row L4, L5, L6 are not parallel to the corresponding magnetic field axes MC3, MC4, MC6 (ie, Phase difference). For example, there may be an angle difference of θ21, θ22, θ23 between the corresponding central axes CL3, CL4, CL6 and the magnetic field axes MC3, MC4, MC6. θ21, θ22, and θ23 may be acute angles in a second direction (eg, clockwise direction) about the center axes CL3, CL4, and CL6. Meanwhile, the angle differences θ21, θ22, and θ23 between the corresponding central axes CL3, CL4 and CL6 and the magnetic field axes MC3, MC4 and MC6 may be completely the same. Alternatively, the angle differences θ21, θ22, and θ23 may be different from each other. Alternatively, θ21 and θ22 may be the same as each other, and θ23 may be different from θ21 and θ22. This angle difference can be changed depending on the design.

The shape of the unbalanced magnetic vector wave is not limited to FIG. 9. For example, in FIG. 8, the central axes CL3, CL4 and CL6 and the magnetic field axes MC3, MC4 and MC6 cross each other, but are not limited thereto. The central axes CL3, CL4, CL6 and the magnetic field axes MC3, MC4, MC6 may have other shapes as long as they are not parallel to each other (or there is a phase difference). For example, if the magnet unit 221 has a trapezoidal shape (shape similar to a trapezoid), the magnetic axis may be arranged alongside the inclined side (left side or right side) of the trapezoidal shape. That is, the magnetic axis may be formed long along the inclined side.

On the other hand, the third part 123 (magnet arrangement) of the rotating body 120 is substantially the same as the second part 122 (magnet arrangement) of the rotating body 120. The second nonrotating body 171 (magnet arrangement) is substantially the same as the first nonrotating body 170 (magnet arrangement). Arrangement relationship between the third portion 123 and the second non-rotating body 171 of the rotating body 120, arrangement relationship between the second portion 122 and the first non-rotating body 170 of the rotating body 120 Is substantially the same as

In summary, the second non-rotating body 171 and the third portion 123 of the rotating body 120 are disposed to face each other. A plurality of fourth magnet units 271a, 272a, and 275a may be arranged on the second non-rotating body 171 in a plurality of rows (for example, three rows). On the third portion 123 of the rotating body 120, a plurality of third magnet units 221a, 222a, and 225a may be arranged in a plurality of rows (eg, three rows).

In addition, the third magnet units 221a, 222a and 225a and the fourth magnet units 271a, 272a and 275a may have an unbalanced magnetic vector wave. The central axis and magnetic field axes of the third magnet units 221a, 222a, and 225a are not parallel to each other (there are phase differences), and the central axis and magnetic field axes of the fourth magnet unit 271a, 272a, and 275a are not parallel to each other (phase differences There is).

On the other hand, depending on the design, the arrangement of the magnet units 221, 222, 225, 221a, 222a, and 225a on the rotating body 120, and the magnet units 271, 272, 275, 271a, on the non-rotating bodies 170 and 171, The arrangement of 272a, 275a may be reversed. That is, the magnet units 221, 222, 225, 221a, 222a, and 225a on the rotating body 120 are disposed without phase difference with each other (for example, similar to FIG. 4), and the magnets on the non-rotating bodies 170 and 171. Units 271, 272, 275, 271a, 272a, and 275a may be arranged such that phase differences exist with each other (eg, similar to FIG. 8).

On the other hand, depending on the design, the angle differences θ21, θ22, and θ23 of the magnet units 221, 222, and 225 disposed on one surface of the rotating body 120 are magnet units 221a, 222a, and 225a disposed on the other surface. ), The angle difference may be different. For example, in the magnet unit 221, the angle difference θ21 between the central axis and the magnetic field axis may be 30 °, and in another magnet unit 221a, the angle difference between the center axis and the magnetic field axis may be 40 °.

In addition, depending on the design, the method of arranging the magnet units 221, 222, and 225 disposed on one surface of the rotating body 120 and the method of arranging the magnet units 221a, 222a, and 225a arranged on the other surface are different from each other. Can be. For example, in FIG. 9, the magnet unit 222 may be disposed 5 ° clockwise than the magnet unit 221, and the magnet unit 225 may be disposed 8 ° clockwise than the magnet unit 222. have. On the other hand, the magnet unit 222a may be disposed 3 ° counterclockwise than the magnet unit 221a, and the magnet unit 225 may be disposed 10 ° counterclockwise than the magnet unit 222.

Next, the magnetic gear 321 will be described with reference to FIGS. 10 and 11. 10 and 11 show an exemplary configuration of the magnetic gear. 10 and 11 are cross-sectional views taken along line B-B of FIG. 2. 12A and 12B are conceptual views for explaining the magnetic field of the magnet unit used for the magnetic gear. 13 and 14 are diagrams for explaining the relationship between the magnetic gear of the first magnetic force component and the magnetic gear of the second magnetic force component.

Referring to FIG. 10, the magnetic gear 321 may include a few (eg, one or two) magnet units 3210. In this case, the magnet unit 3210 may be formed to surround the first portion 121.

Referring to FIG. 11, the magnetic gear 321 may include a plurality of magnet units 3210a and 3210b. As shown, the magnet unit 3210a of the first polarity (eg, N pole) and the magnet unit 3210b of the second polarity (eg, S pole) may be repeatedly arranged. However, if necessary, two or more magnet units 3210a of the first polarity may be disposed, and then the magnet units 3210b of the second polarity may be disposed. On the contrary, after two or more magnet units 3210b of the second polarity are arranged, the magnet units 3210a of the first polarity may be disposed.

12A and 12B, the first magnet units 271, 272 and 275 to the fourth magnet units 271a, 272a and 275a have an unbalanced magnetic vector wave, while the magnets used for the magnetic gear 321. Units 3210, 3210a, and 3210b may have a balanced magnetic vector wave. That is, the magnitudes of all the magnetic vector waves MV21 coming from the surfaces of the magnet units 3210, 3210a and 3210b may be constant. In other words, the magnet units 3210, 3210a, and 3210b may not have a magnetic axis (the connecting line of the largest magnetic force vector waves, for example, MC1 of the first magnet unit 271).

The size and shape of the magnet units 3210, 3210a, and 3210b may vary depending on the magnetic force strength, the size (diameter) of the first portion 121, and the like.

Meanwhile, as illustrated in FIGS. 13 and 14, the shape of the magnetic gear 321 of the first gear component 100 and the shape of the magnetic gear of the second gear component 101 may be complementary to each other. 13 and 14, a case is not shown for convenience of description.

As shown in FIG. 13, when the magnetic gear 321 of the first gear component 100 uses the magnet unit 3210 of one first polarity, the magnetic gear of the second gear component 101 is also one. The magnet unit 3310 of the second polarity can be used.

As shown in FIG. 14, the magnetic gear 321 of the first gear component 100 includes a magnet unit 3210a of a first polarity (eg, N pole) and a second polarity (eg, S pole). If the magnet unit 3210b of) is repeatedly arranged, the magnetic gear of the second gear component 101 also has the magnet unit 3310a of the first polarity (eg, N pole) and the second polarity (eg, The magnet unit 3310b of the S pole) may be repeatedly arranged.

As the magnetic gear 321 of the first gear component 100 rotates (R1), the attraction force between the magnet unit 3210a of the first polarity and the magnet unit 3310b of the second polarity and the magnet of the second polarity The attractive force between the unit 3210b and the magnet unit 3310a of the first polarity causes the magnetic gear of the second gear component 101 to rotate (R2).

As such, the magnetic gear may transmit the rotational motion in a non-contact manner without engaging the teeth by using the attraction force of the magnet units 3210, 3310, 3210a, 3210b, 3310a, and 3310b. Since the magnetic gear can rotate in a non-contact manner, it can be used in a clean room, lubricating oil is unnecessary, and replacement by wear and damage is also unnecessary. Therefore, it is possible to use the magnetic gear without maintenance for quite a long time.

Here, the operation of the first gear component 100 will be described with reference to FIGS. 15 and 16. 15 is a diagram for explaining a magnetic field tornado and a magnetic field cyclone. FIG. 16 is a view for explaining a method of driving the first magnetic force component (magnetic field surfing).

Subsequently, referring to FIGS. 1, 4, 8, and 15, the first non-rotating body 170 and the second portion 122 of the rotating body 120 face each other, but the first from the shaft 110. The distance P11 from the column L1 (ie, the first magnet unit 271 of the first column L1) and the fourth column L4 from the shaft 110 (ie, the fourth column L4). The distance P12 to the second magnet unit 221 may be different.

Similarly, the distance from the axis 110 to the second column L2 and the distance from the axis 110 to the fifth column L5 may be different. The distance from the axis 110 to the third column L3 and the distance from the axis 110 to the sixth column L6 may be different.

In particular, when the first magnet unit 271 and the second magnet unit 221 are S poles, the distance P12 may be shorter than the distance P11.

Similarly, the distance P11a from the shaft 110 to the fourth magnet unit 271a and the distance P12a from the shaft 110 to the third magnet unit 221a may be different from each other. In addition, the distance from the shaft 110 to the fourth magnet unit 272a and the distance from the shaft 110 to the third magnet unit 222a may be different from each other. The distance from the shaft 110 to the fourth magnet unit 275a and the distance from the shaft 110 to the third magnet unit 225a may be different from each other.

Here, when the fourth magnet unit 271a and the third magnet unit 221a are N poles, the distance P11a from the shaft 110 to the fourth magnet unit 271a is the third magnet unit from the shaft 110. It may be longer than the distance P12a to 221a.

Referring to FIG. 15, by adjusting the distances P11, P12, P11a, and P12a as described above, a large flow of the magnetic field may be generated in the power generating device.

A staggered arrangement of a plurality of fourth magnet units 271a, 272a, and 275a and a plurality of third magnet units 221a, 222a, and 225a (that is, a portion of the fourth magnet units 271a, 272a, and 275a and a third magnet) By virtue of some of the units 221a, 222a, 225a), the flow of the magnetic field is concentrated as it rotates from outside (outer circumference) to the center (see reference numeral M2) (this is referred to herein as the magnetic field tornado).

In addition, a staggered arrangement of the plurality of first magnet units 271, 272, and 275 and the plurality of second magnet units 221, 222, and 225 (that is, a portion of the first magnet units 271, 272, and 275) may be used. Part of the two magnetic units 221, 222 and 225 face each other, whereby the flow of the magnetic field spreads outwardly (outer peripheral part of the outer part) while rotating in the center (see reference numeral M1) Called clones).

That is, the arrangement of such magnetic units in the rotating body 120, the first non-rotating body 170, and the second non-rotating body 171 is "outside (outer circumference) → rotation center → rising center part → (rotation diffusion). By this, a "rotation cycle" can be formed (induced) in the "outer (outer peripheral part of outer side)" direction. This is a Mobius cyclone phenomenon, leading to magnetic field induction.

Large magnetic field flows, such as magnetic field tornadoes and magnetic cyclones, help to rotate the rotor 120 stably. A continuous magnetic field Mobius rotation routine is formed to produce a rotational effect.

Here, the rotating body 120 includes a first recessed part 1120 and a second recessed part 1121, and second magnet units 221, 222, and 225 are disposed in the first recessed part 1120. When the third magnet units 221a, 222a, and 225a are disposed in the second recesses 1121, such magnetic tornado and magnetic field cyclones may be larger. Because the first recessed part 1120 and the second recessed part 1121 are present, the interval A between the first recessed part 1120 and the second recessed part 1121 becomes short. Therefore, the process of changing from the magnetic field tornado to the magnetic field cyclone can be performed with minimal leakage of the magnetic field.

In addition, the rotating body 120 includes a first recessed part 1120 and a second recessed part 1121, and the first non-rotating body 170 and the second non-rotating body 171 respectively have a first protrusion 1170. And a second protrusion 1171. By doing so, the distance between the plurality of first magnet units 271, 272, 275 and the plurality of second magnet units 221, 222, 225, the plurality of third magnet units 221a, 222a, 225a and the plurality of Stably adjust the distance between the fourth magnet units 271a, 272a, and 275a, and repulsion between the plurality of first magnet units 271, 272, and 275 and the plurality of second magnet units 221, 222, and 225, The repulsive force between the plurality of third magnet units 221a, 222a, and 225a and the plurality of fourth magnet units 271a, 272a, and 275a may be maximized. In addition, since the first recessed part 1120 faces the first protrusion 1170 and the second recessed part 1121 faces the second protrusion 1171, the rotary body 120 and the first recessed part 1120 in the minimized space. The first non-rotating body 170 and the second non-rotating body 171 may be implemented.

1, 4, 8 and 16, first, the power supply unit supplies power for a first period. The first period includes the size of the rotating body 120 / the first non-rotating body 170 / the second non-rotating body 171, the size / magnetic force of the first magnet units 271, 272, and 275, and the second magnet unit 221. , Size / magnetic force of 222, 225, size / magnetic force of third magnet unit 221a, 222a, 225a size / magnetic force of fourth magnet unit 271a, 272a, 275a, size / magnetic force of magnetic gear 321 And so on.

The first period may be, for example, a period during which the rotor 120 is sufficiently rotated so that the rotor 120 may have inertia. For example, the power supply unit may provide power only for a period during which the rotating body 120 rotates 1000 to 3000 revolutions.

Then, the power supply does not supply power for the second period after the first period. Even without power supply, the rotating body 120 may continuously rotate using magnetic field surfing.

After the second period, the power supply may again supply power. As such, the power supply unit may periodically repeat the operation of supplying / blocking power.

On the other hand, depending on the design, the power supply unit may continuously supply power.

On the other hand, when the surfing operation of the rotating body 120 is not desired (or the surfing operation of the desired degree is not performed), the interval between the first non-rotating body 170 and the rotating body 120, the second fly ash The distance between the whole 171 and the rotating body 120 may be adjusted to try again.

As such, while the rotating body 120 of the first gear component 100 rotates, the magnetic gear 321 of the first gear component 100 and the magnetic gear of the second gear component 101 perform a gear operation. .

Meanwhile, the magnetic field surfing operation will be described in more detail with reference to FIG. 16. At time t1, the first magnet unit 271 of the first row L1 and the second magnet unit 221 of the fourth row L4 are described. As these intersect each other (or overlap each other), a first repulsive force RP1 begins to occur.

Since the first repulsive force RP1 becomes larger as the crossing area (overlap area) between the first magnet unit 271 and the second magnet unit 221 increases, the first repulsive force RP1 rotates while the rotating body 120 rotates. Becomes bigger.

At time t2, the second repulsive force RP2 crosses (or overlaps with) the first magnet unit 272 of the second row L2 and the second magnet unit 222 of the fifth row L5. It starts to occur. This is because the second magnet unit 222 of the fifth row L5 is disposed behind the second magnet unit 221 of the fourth row L4 with a phase difference.

At time t3, the third repulsive force RP3 crosses (or overlaps with) the first magnet unit 275 of the third row L3 and the second magnet unit 225 of the sixth row L6. It starts to occur.

In summary, when the second magnet unit 221 of the fourth row L4 starts to overlap with the first magnet unit 271 of the first row L1, and the second magnet of the fifth row L5 The time at which the unit 222 starts to overlap with the first magnet unit 272 in the second row L2 is different. Therefore, as described above, the fixed magnetic force vector waves of the first nonrotating body 170 and the second nonrotating body 171 are surfaced by the rotating magnetic force vector waves of the rotating body 120. Further, θ11, θ12, and θ13 may be acute angles in a counterclockwise direction about the central axis CL, and θ21, θ22, and θ23 may be acute angles in a clockwise direction about the central axes CL3, CL4, CL6. Due to this configuration, when the rotating body 120 rotates, the rotating magnetic force vector waves of the rotating body 120 and the fixed magnetic force vector waves of the first non-rotating body 170 and the second non-rotating body 171 are mutually continuous. Connected.

As described above, the rotor 120 may rotate between the first non-rotator 170 and the second non-rotator 171.

FIG. 18 is a conceptual diagram for explaining a relationship between a plurality of first magnet units installed in the non-rotating body of FIG. 17. 19 is a diagram illustrating a rotating body, and may be a surface facing the first non-rotating body. FIG. 20 is a conceptual diagram for explaining a relationship between a plurality of second magnet units installed in the non-rotating body of FIG. 19.

 First, referring to FIG. 17, a plurality of first magnet units 271, 272, and 275 spaced apart from each other are disposed in each column L1, L2, and L3. Specifically, the number of the plurality of first magnet units 271 arranged in the first column L1, the number of the plurality of first magnet units 272 arranged in the second column L2, and the third column The number of the plurality of first magnet units 275 disposed at L3 may be the same. For example, eighteen first magnet units 271, 272, and 275 may be disposed in each row L1, L2, and L3.

Referring to FIG. 19, a plurality of second magnet units 221, 222, and 225 spaced apart from each other are disposed in each row L4, L5, and L6. The number of the plurality of second magnet units 221, 222, and 225 arranged in the rows L4, L5, and L6 is different from each other.

As described above, at least a portion of the first column L1 and at least a portion of the fourth column L4 face each other, and at least a portion of the second column L2 and at least a portion of the fifth column L5 face each other. At least a portion of the third column L3 and at least a portion of the sixth column L6 may face each other.

In this case, the number of the second magnet units 221 arranged in any one row (for example, L4) among the plurality of rows L4, L5, and L6 of the rotating body 120 is equal to the number of rows facing each other. For example, the number of first magnet units 271 disposed in L1 may be equal to each other.

In addition, the number of the second magnet units 222 and 225 disposed in the remaining rows (for example, L5 and L6) among the plurality of rows L4, L5 and L6 of the rotating body 120 may correspond to the rows that face each other ( For example, the number of first magnet units 272 and 275 disposed in L2 and L3 may be different. In particular, the number of the second magnet units 222 arranged in any one of the remaining columns (eg, L5 and L6) (eg, L5) is arranged in the opposite rows (eg, L2). It may be smaller than the first magnet unit 272 to be. On the other hand, the number of the second magnet units 225 disposed in any one of the remaining columns (eg, L5 and L6) (eg, L6) is disposed in the opposite rows (eg, L3). There may be more than the first magnet unit 275 to be.

For example, eighteen first magnet units 271, 272, and 275 are disposed in the rows L1, L2, and L3 of the first non-rotating body 170, respectively. The number of the second magnet units 221 arranged in the fourth row L4 of the rotating body 120 is 18, the number of the second magnet units 222 arranged in the fifth row L5 is 16, The number of the second magnet units 225 disposed in the sixth column L6 may be twenty.

That is, one sidewall (left sidewall) of the three second magnet units 221, 222, and 225 may be arranged to be substantially parallel to each other.

For example, the size (or width) of the second magnet unit 221 disposed in the fourth row L4 and the distance W4 between the neighboring second magnet units 221 are constant. The size (or width) of the second magnet unit 222 disposed in the fifth column L5 and the distance W5 between the neighboring second magnet units 222 are constant. The size (or width) of the second magnet unit 225 disposed in the sixth row L6 and the distance W6 between the neighboring second magnet units 225 are constant. The number of the second magnet units 221, 222, and 225 arranged in each column is different from each other. If these conditions are satisfied, these points PB1 and PB2 depend on the greatest common divisor of the number of the second magnet units 221, 222, 225 arranged in each row L4, L5, L6 of the rotor 120. Can vary. In detail, the numbers of the second magnet units 221, 222, and 225 disposed in the columns L4, L5, and L6 may not be equal to each other, and may have a maximum common divisor of two or more. In FIG. 19, since the greatest common divisor of 18, 16, and 20 is 2, two points PB1 and PB2 may be generated. For example, if the number of columns L4, L5, L6 is 16, 12, 20, since the greatest common factor is 4, four points may occur.

Referring to FIG. 18, when two straight lines a1 and a2 are drawn outwardly about the axis 110, a part of the sidewalls of the first magnet unit 271 of the first row L1, and the second row A portion of the sidewall of the second magnet unit 272 of L2 and a portion of the sidewall of the first magnet unit 275 of the third row L3 may touch two straight lines a1 and a2. For example, the sidewalls of the first magnet units 271, 272, and 275 are inclined more than the straight lines a1 and a2.

Similarly, referring to FIG. 20, the straight line a13 facing outward about the axis 110 may contact a portion of the sidewall of the second magnet unit 221 of the fourth row L4. The straight line a14 facing outward about the axis 110 may contact a portion of the sidewall of the second magnet unit 222 of the fifth row L5.
