Description

"ROTATIVE MECHANISM"

Technical Field

The present invention relates to a rotary mechanism constituting a rotational body structure in an electric generator, motor or the like, and more particularly to a rotary mechanism of the type having a vertically extending axis of rotation.

Background Art

As an example of such a rotary mechanism, an electromagnetic rotary machine with a magnet rotor has been proposed (for example, see patent document 1).

Description of the Invention

Problem to be solved by the Invention

The present invention has been proposed in view of the above prior art problem and is intended to provide a rotary mechanism which exhibits very high rotational efficiency.

Ways to Solve the Problem

A rotary mechanism according to the present invention is characterized in that it comprises: a fixed member (1) having a bearing (16, 18); a pivot member (2) including a pivot axis (21) pivoted by the bearing and a disc member (22) provided about the pivot axis; a plurality of coils (3) which are mounted on the fixed member (1) and arranged at regular intervals on a circle centered on the axis of rotation (21); and a first permanent magnet (4) mounted on the disc member (22), wherein the first permanent magnets (4) are arranged at regular intervals in a circle centered on the axis of rotation (21) and arranged to be positioned opposite of the coils (3) (claim 1).

Here, it is preferable that the coil (3) is penetrated by a core member of non-magnetic material (eg stainless steel) and that a magnetic material member (eg iron disk or iron plate) is located at its end face away from its end face opposite the first permanent magnet (4) (claim 2).

It is preferable that a plurality of arm members (24) be fitted to disc member (22), a second permanent magnet (5) being held at the tip of arm member (24) by a first magnet support member (24h). ), a third permanent magnet (6) being provided radially outwardly of the arm member (24) in an area of the fixed member (1), the third permanent magnet (6) being held by a second magnet support member ( 1 lh), and a repulsive force being generated when the second permanent magnet (5) moves in a direction of rotation (R) from a condition where the second permanent magnet (5) is in the same circumferential position as the third permanent magnet (6) (condition in which the second permanent magnet 5 and the third permanent magnet 6 are aligned 24Lc).

Here, it is preferable that the number of such third permanent magnets (6) is greater than the number of such arm members (24).

It is preferable that the first magnet support member (24h) be made of a non-magnetic material (eg aluminum or plastic) and surrounds the second permanent magnet (5) and forms an open area (240h) that allows radiation of magnetic force lines from the second permanent magnet (5), the second magnet support member (Ilh) is made of magnetic material (eg nickel-chrome steel), and surrounds the third permanent magnet (6) and forms an open area (1 10h) that allows radiation of magnetic force lines from the third permanent magnet (6), and when the open area (240h) of the first magnet support member (24h) and the open area (IlOh) ) of the second magnet support member (Ilh) are not positioned opposite each other, no magnetic interaction occurs between the second permanent magnet (5) and the third permanent magnet (6), but when the open area (240h) and the open area (IlOh) are positioned opposite each other, the There is a magnetic repulsion between the second permanent magnet (5) and the third permanent magnet (6) (claim 4).

It is preferable for a fourth permanent magnet (8) to be mounted on a lower surface of the disc member (22), a fifth permanent magnet (9) to be provided on the fixed member (1) in an area below the fourth permanent magnet (8). , and the fifth permanent magnet (9) is arranged to be positioned opposite the fourth permanent magnet (8) and has the same polarity as the fourth permanent magnet (8) (claim 5).

Here it is preferable that the fourth permanent magnet (8) be mounted on the lower surface of the disc member (22) by a stainless steel socket (bracket) and the fifth permanent magnet (9) is mounted on the fixed member (1). by a stainless steel socket (bracket).

It is preferred that the fixed member (1) be composed of an upper frame (11) and a lower frame (13), which are regular polygonal circular or annular, and a connecting member (1 lb) that connects the upper frame (1). 11) and the lower frame (13).

Effects of the Invention

In the above rotary mechanism, because it includes multiple coils (3) arranged at regular intervals at a circumference about the fixed member (1) and the first multiple permanent magnets (4) positioned opposite the coils (3) of the rotation member ( 2), when the rotational body (2) is first rotated by a given means to initiate rotation, an induced current is generated in coil (3) according to Fleming's left hand rule. The induced current generated in coil (3) works to rotate the first permanent magnet (4) in the same direction as when it was initially rotated.

In other words, since the rotational body (2) has been rotated, for example by a motor, then an induced current is generated in the coil (3) and, based on the principle of the so-called "Aragon disk", it It works to encourage rotational body rotation, thus ensuring very high rotation efficiency.

If the coil (3) is penetrated by a core member of non-magnetic material (eg stainless steel) and a magnetic material member (eg iron disk or iron plate) is located on its end face away from its end face opposite the first permanent magnet (4) (claim 2), the magnetic material member intensifies the magnetic field generated in the coil (3) and, also, if the core member is made of a non magnetic material, stainless steel in particular, a magnetic field appropriately passes through the core member and thus a magnetic field is appropriately generated from the coil (3).

In addition, because the core member is of a non-magnetic material, it is not attracted to the first permanent magnet (4), which prevents the rotational body from being braked. Here, because the magnetic material member is spaced from the first permanent magnet (4), it is less likely to be attracted to the first permanent magnet (4).

In the present invention, if multiple arm members (24) are provided, a second permanent magnet (5) is held over the tip of the arm member (24) by a first magnet support member (24h), a third permanent magnet (6) is provided radially outwardly of the arm member (24) in an area of the fixed member (1), and the third permanent magnet (6) is held by a second magnet support member (Ilh) (claim 3). (4), the magnetic repulsion between the second permanent magnet (5) and the third permanent magnet (6) rotates the arm member (24) and adds torque to the disc member (22). As a consequence, rotation is encouraged without the external current supply.

In other words, if the action taken by the coil (3) and the first permanent magnet (4) is considered the main action, the second permanent magnet (5) and the third permanent magnet (6) work to increase the action.

If a fourth permanent magnet (8) on the rotating side and a fifth permanent magnet (9) are provided, the fifth permanent magnet (9) is positioned opposite the fourth permanent magnet (8) and its face opposite to the The fourth permanent magnet (8) has the same polarity as the fourth permanent magnet (8), so that the fourth permanent magnet (8) on the rotating side and the fifth permanent magnet (9) on the fixed side repel each other. each other (claim 5), working the magnetic repulsion between the permanent magnets (8, 9) so that the full rotating member (2) floats from the fixed member (1).

As a consequence, the thrust exerted on the fixed limb (1) by the rotating limb (2) can be reduced near zero and the friction caused by the thrust can be reduced near zero.

By combining all the above structures and their actions, the rotating friction of the rotating member (2) is reduced close to zero, resulting in a rotary mechanism with very high rotational efficiency.

Furthermore, in the present invention, multiple coils are arranged as a ring between the fourth permanent magnet (8) and the fifth permanent magnet (9), coil ring arrangements are vertically spaced, the polarities of the vertically spaced coil arrangements are thus determined to generate a repulsive force, and multiple air core coils, with their open ends facing up and down, are located between vertically spaced arrangements of magnets to generate electrical energy.

The electrical energy generated by the air core coils between the upper and lower arrangements of the magnets can drive, for example, a motor mounted on top of the disc member (22). Or the electrical energy generated by the air core coils may drive, for example, a motor provided to rotate the disk member (22) only.

Here, the "motor provided for rotating the disc member (22) only" is connected to the disc member (22) via a gear or belt and thus it is possible for the disc member (22) to rotate even when the disc is rotated. rotation axis (21) is not connected to a drive source. When electrical energy is generated by rotating the coil arrangements arranged as rings together with the disc member (22), it is also possible to rotate only the disc member (22) without rotating the rotation axis (21). Here, if the disc member (22) is structured to be able to rotate relative to the axis of rotation (21), the disc member (22) can be rotated more effectively by securing the axis of rotation (21) ) and leaving a thrust bearing provided therein to support the weight of the disc member (22).

Further, with respect to the upper and lower magnet ring arrangements, by securing the lower magnet arrangement and mounting the upper magnet arrangement to the disk member (22), the disk member (22) may be floated by repulsion. between poles of the same polarity. Also, as described above, electrical energy can be generated in the air core coils by rotating the disc member (22).

In this case, the electrical energy of the disc member 22 improves the effect obtained by a magnetic force.

Best Mode for Carrying Out the Invention

In the following, embodiments of the present invention will be described with reference to the accompanying drawings.

First, a rotary mechanism 100, as the first embodiment (embodiment) will be described with reference to figures 1 to 11.

The rotary mechanism, the whole being represented by reference numeral 100 in Figures 1 and 2, includes a fixed member 1, a rotating member 2, a plurality of coils 3 mounted on the fixed member 1, and a plurality of first permanent magnets. 4 mounted on the rotating member 2.

The fixed member 11 is a three-layer structure in which an upper frame 11, a middle frame 12 and a lower frame 13 are stacked through eight connecting members 11b with spaces in the vertical direction (see figure 2). Specifically, the upper frame 11 is formed as an equilateral-octagonal structure assembled by eight-membered connection ends 11a with the same cross-section profile (slot-type cross-section) through connection members 11b (see Figure 1).

Although not clearly shown in Figure 1, the middle frame 12 has the same contour as the upper frame I and, as the upper frame 11, is formed as an equilateral-octagonal structure assembled by eight-member connecting ends 12a therewith. cross section profile (slot type cross section) through connecting members 11b (see figure 2).

Although not clearly shown, the lower frame 13 has the same contour as the upper frame 11 and is an eight-membered equilateral-octagonal structure 13a with a groove-type cross-section which is larger than the upper frame 11 and the middle frame 12 (in terms of size in the vertical direction of figure 2) (see figure 2).

In Figure 1, in the upper frame 11, members with a slot-type cross-section 11a, 11a, left and right in Figure, are connected and reinforced by two beams Ilc running parallel to each other horizontally in Figure. The two beams Ilc are vertically symmetrical with respect to the center point O of the rotation member 2 (center of rotation, which is also the center point of the upper frame 11).

In figure 1, in upper frame 11, upper member 11a-1 and upper beam 11c-1 are connected by two beams Ild running parallel to each other vertically in figure 1, and lower member 11a-2 and lower beam 11c -2 are connected by two Ild beams running parallel to each other vertically in the figure, thereby reinforcing the entire upper frame 11.

Although not clearly shown, like the upper frame 11, in the middle frame 12, the members with a slot-type cross section 12a, 12a on the left and right are connected and reinforced by two beams 12c (see figure 2). running parallel to each other horizontally in figure 1.

The two beams 12c are symmetrical with respect to the center point O of the middle frame 12 vertically in figure 1.

Moreover, like the upper frame 11, described in reference to figure 1, in the middle frame 12, the upper member 12a in figure 1 (which rests in the same position as the member 1a-1 in figure 1) and the upper beam 12c (which rests in the same position as beam llc-1 in figure 1) are connected by two beams 12d (not shown) (which run parallel to each other vertically in figure 1). And lower member 12a (which rests in the same position as member 1a-2 in figure 1) and lower beam 12c (which rests in the same position as beam 11c-2 in figure 1) are connected and reinforced by two beams 12d (not shown) (which run parallel to each other vertically in Figure 1).

Referring to Figure 2, the lower frame 13 is mounted on the upper surface of a base member 14 in a manner for positioning thereon and the outer rim of the base member 14 is smaller than the outer rim of the lower frame. 13. A reinforcing member 14a is provided in the center of the base member 14.

In Figure 1, a bearing support plate 15 is supported by the two beams 11c, Ilc in an area between the two beams 11c, Ilc of the upper frame 11, which also corresponds to the center of the upper frame 11. A radial bearing 16 (bearing above) is provided on the upper surface of the bearing support plate 15. Here, the radial bearing 16 is located with its central geometric axis perpendicular to the paper surface of Figure 1.

A bearing support plate 17 is located in the center of the reinforcing member 14a (provided in the center of the base member 14) and a lower bearing 18 is fitted in the center of the bearing support plate 17 (upper surface in figure 2). Here, the lower bearing 18 has a structure that combines a radial bearing 18A and a thrust bearing 18B, and is thus located so that the central axis of the lower bearing 18 extends vertically in figure 2 (direction perpendicular to the paper surface). of figure 1).

In the embodiment shown in Figure 2, a radical bearing (middle bearing) 19 is also fitted at the center of the middle frame 12.

As noted in Figure 2, the middle bearing center axis 19 and the upper bearing center axis 16 overlap to an extent of the lower bearing center axis 18.

The axis of rotation 21 is articulated by upper bearing 16, middle bearing 19 and lower bearing 18.

On the pivot axis 21, a disc member (e.g. an aluminum disc) 22 is fixed to the pivot axis 21 through a hub 20 in the area between the upper bearing 16 and the middle bearing 19.

In other words, the rotating member 2 has, as main components, a rotating axis 21 and a disk member 22 ,.

As will be described below, the rotation of the aluminum (or plastic) disk 22 is associated with the "Aragon disk" principle on which electricity consumption meters are based.

Here, the axis of rotation 21 is made of non-magnetic material, such as stainless steel, to avoid the influence of a fourth and a fifth permanent magnet, which are described later.

The disc member 22 has a mass above a given level to exert a torque sustaining effect, such as a so-called flywheel (pulley).

When using synthetic resin or aluminum as the material for disc member 22, the material becomes more efficient. Referring to FIGS. 3 and 4, on disc member 22, a plurality of permanent magnet retaining clips 23, which have an L-shaped cross-section, are fitted at regular intervals, all around the outer rim of the disc member. disc 22. Here, in Figures 3 and 4, for a simple illustration, only one securing clip 23 is shown and the other securing clips 23 are not shown.

Although not shown in Figures 3 and 4, it is also possible to provide an annular member 23 instead of multiple securing clamps 23, so that annular member 23 is mounted on disk member 22 via an adapter 23b.

In Figures 3 and 4, a first permanent magnet 4 is fitted to the radially inner surface (surface closest to the axis of rotation 21) of a flange portion 23a of each securing clamp 23. Here, the first permanent magnets 4 located adjacent to the along the circumferential direction, they are arranged in such a way that the polarities of their radially internal surfaces alternate between the N pole and the S pole.

The cross-section of the clamp 23, shown in Figure 4, is a cross-section at a special point where an arm member 24 (which will be described below) is mounted on the upper surface of the disc member 22 (cross section indicated by Y in figure 1).

Although not shown, in a common cross section without an arm member 24, the height of the flange part 23a of the retaining clip 23 and the position of the first permanent magnet 4 are greater than the height of the flange part 23a and the position of the first permanent magnet 4, as shown in figure 4, in an amount equivalent to the thickness of an arm member 24.

Although not shown in FIGS. 1 and 2, the reference numeral Ile in FIG. 4 represents a roof covering the upper portion of the rotary mechanism 100. The roof ILE covers all areas except limbs 11a, beams 11c, lld beams of the upper frame Ilea bearing support plate 15.

In Fig. 4, an L-shaped clamping clamp for a coil, llf, is provided at a distance of r1 (radial distance) from the axial center 21c of the rotation axis 21 with its top facing downward in Fig. 4. Multiple clamping clips lf are provided, all around the disc member 22 at regular intervals.

Here, the radial distance drl of the coil securing clamp 1 If is shorter than the radial distance r2 of the securing clamp 23 (radial distance from the axial center 21c of the securing clamp 23).

A coil 3 is adapted to the side of the coil securing clip 1f (radially facing side) opposite the permanent magnet securing clip 23 by a means which will be described later. Here, coil 3 is a so-called electromagnetic coil that generates a magnetic field when energized. More specifically, coil 3 is thus structured such that when coil 3 is energized, a magnetic field is generated in coil 3 and the magnetic field causes a mutual inductance to occur between coil 3 and the first permanent magnet 4.

When the first permanent magnet 4 rotates together with the disc member 22 and crosses the magnetic field of coil 3, an induced current is generated in coil 3. If rotational body 2 is rotated by a given means, for example according to Faraday's law, a small motor (not shown), an induced current is generated in coil 3 when the first permanent magnet 4 passes (the magnetic field of) coil 3.

Due to the induced current generated in coil 3, the first permanent magnet 4 and disk member 22 are urged to rotate in the same direction as they were initially rotated. As a consequence, since the rotating member 2 has been rotated by some means (for example, a motor), the induced current generated in coil 3 impels the rotating member 2 to continue rotating.

Although not clearly shown, the first embodiment is structured as a type in which the rotating member rotates upon starting a small engine (to start) and thus structured so that a clutch means is interposed. between the rotary shaft and the starter motor and when the rotating member reaches a prescribed rotational speed, the clutch is switched off.

In the following, with reference to figures 5 to 7, the detailed position relationship between the coil 3 and the first permanent magnet 4 and the detailed coil structure will be described.

In Figures 5 to 7, coil 3 includes a coil body 32, a plate member 33 provided at one end of the coil body 32, and a pressure plate 34 for pressing plate member 33 in figure 5. Here , the pressure plate 34 is made of a non-magnetic material for the reason which will be described later.

The coil body 32, plate member 33 and pressure plate 34 are penetrated by a stainless steel core member 35 which also serves as a long through bolt.

An outer thread 35t (male) is formed over the 35's portion of the stainless steel core member, except its portion penetrating the coil body 32. A first nut N1 is screwed onto the outer thread 35t and by tightening the first nut N1, the gap between plate member 33 and pressure plate 34 is shortened.

An N2 nut is bolted to the outer thread 35t in a region where the stainless steel core member 35 penetrates the clamp arm ld of the spool. And the coil 3 is fitted to the coil clamp 11f by sandwiching the coil clamp 11f with nut N2.

Figure 7 is a sectional view of the center of coil 3 in the longitudinal direction (left / right direction in figures 5 and 6).

In Figures 5 and 6, reference numeral 36 represents a plate member (iron plate) of magnetic material (e.g. iron) with a through hole for a screw in its center.

A conventional coil often uses an iron core in the center of the coil to increase magnetic flux density. However, in the first illustrated embodiment, a problem occurs namely that the core member of the coil 3 moves in close proximity to the permanent magnet 4 (see figures 5 and 6) if the core member of the coil 3 is In an iron core, the core member of the coil 3 will be attracted to the permanent magnet 4 and the attractive force will slow the rotation of the disk member 22.

Here, if it is made of stainless steel, it will not be attracted to the permanent magnet, but will allow a magnetic field to pass through it.

Thus, the coil 3 used in the first embodiment employs a stainless steel core member 35 as the core member of coil 3 to prevent the core member of coil 3 from being attracted to permanent magnet 4. In addition, because the magnetic field passes through the stainless steel core member 35, when the stainless steel core member 35 is inserted into coil 3, the effect of coil 3, ie the effect of encouraging the rotation of disk member 22 by the magnet Permanent 4 as an electromagnet and self-inductance, is not prevented.

Moreover, in the first illustrated embodiment, the iron member (iron plate) 36 is disposed at the most remote position of the coil 3 from the permanent magnet 4 (right end in figures 5 and 6), so that the The magnetic field passing through the stainless steel core member 35 is intensified as it passes through the iron plate 36. In other words, the presence of the iron plate 36 ensures the effect of intensifying the magnetic field as in the case of a Ordinary coil that has an iron core in it.

In addition, because the iron plate 36 is located at the most remote position of permanent magnet 4, the risk that the iron plate may be attracted by the magnetic field of permanent magnet 4, and that the rotation of disk member 22 may be braked, is extremely low or negligible.

In summary, due to the use of coil 3, as illustrated in figures 5 and 6, as the permanent magnet passes, a strong magnetic field generated in coil 3 generates an electric current without causing the disc member to rotate braking. 22

Although iron plate 36 is provided on the radially inner side of coil 3 to enhance the magnetic field generated in coil 3, as shown in figures 5 and 6, another possible approach is that, instead of providing an iron disc 36 in Each coil 3, an iron plate (not shown) is located on the radially inner side of the coil retaining clip 11 f (side away from the permanent magnet) and the iron plate is a single continuous ring. This means that this single continuous annular disc has the effect of intensifying, on the radially inner sides of the fixing clips Ilf for the individual coils 3, the magnetic fields generated in the corresponding individual coils 3.

In order to increase the rotational efficiency of the rotary mechanism 100, the first embodiment includes arm members 24 (see figure 1) in addition to the above structure.

In Figures 1 and 8, three arm members 24 (only one shown in Figure 8) extend radially outwardly over the upper surface of disc member 22. As evident in Figure 1, the three arm members 24 are mounted on regular intervals in the circumferential direction.

A fixation 24a holding a second permanent magnet 5 is fitted to the tip of the arm member 24.

As will be described later, in the attachment 24a at the tip of the arm member 24, the second permanent magnet 5 is mainly covered by a support 24h and the support 24h is made of nickel chrome steel, a magnetic material.

Because both permanent magnet 5 and permanent magnet 6 are surrounded by nickel chrome steel, magnetism is reduced.

A fastening 11g supporting the third permanent magnet 6 is fitted to each of the eight connecting members 1b1 of the upper frame 11 of the fixed member 1; and the fixture 1 Ig is oriented radially inwardly (toward the center of rotation O in figure 8).

Here, figure 8 shows that arm member 24 rotates and the center of second permanent magnet 5 comes in a virtual line (not shown in figure 8) connecting third permanent magnet 6 and center of rotation O. Arc Lr in figure 8 depicts the trajectory of the radially outer end of fixture 24a at the tip of arm member 24.

The number of arm members 24 or second permanent magnets 5 (three in the embodiment shown here) and the number of third permanent magnets 6 (eight in the embodiment illustrated here) are determined from the standpoint of "wave ripple" prevention. torque "that could arise as the second multiple permanent magnets 5 simultaneously approached the third permanent permanent magnets 6.

In the following, firstly with reference to Figures 9 and 10, the advantageous effect of the attachment 24a on the arm member 24 (for the second permanent magnet 5) and the attachment Ilg on the upper frame 11 (for the third) will be described. permanent magnet 6), as shown in figure 8, encourage rotation of the disc member 22 (figure 1).

In Figures 9 and 10, the clamp 24a on the arm member is composed of a second permanent magnet 5, a support 24h supporting the second permanent magnet 5 in a manner to cover most of it, and an adjusting member 24b for securing the attachment 24a at the tip of the arm member 24.

The fixture 11g over the upper frame 11 (left in figures 9 and 10) is composed of a third permanent magnet 6, a support 11h holding the third permanent magnet 6 in a way to cover most of it, and an adjusting member 11j to secure the fastener 24a to the connecting member 11b.

In the illustrated embodiment, the holder 24h for holding the second permanent magnet 5 and the holder 11h for holding the third permanent magnet 6 are both made of nickel chrome steel, a magnetic material.

Bracket 24h and bracket 11h cover most of the second permanent magnet 5 or third permanent magnet 6 to prevent magnetic field leakage. However, on its sides positioned opposite each other, ie on the radially outer side of the bracket 24h or nearest side of the connecting member 11b, and the radially inner side of the bracket 11h or the closest side of the arm 24, Permanent magnets are not partially covered by nickel chrome steel.

More specifically, the support 24h for supporting the second permanent magnet 5 takes the form of a cylinder with its bottom closed (see figure 10) and part of its periphery (radially outer part) is cut along the central geometric axis of the cylinder. to expose the second permanent magnet 5 (forming an open area 240h). Although the central geometry axis of the cylinder is not shown here, in Fig. 9 the central geometry extends perpendicular to the paper surface and in Fig. 10 extends up / down or vertically.

In Figure 9, one end of the open area 240h (open area starting point 240h) is in a position delayed by the angle σΐ (15 degrees in the example shown here) of line 24Lc corresponding to the centerline of arm member 24 (one position above the line in figure 9) in the direction of rotation of arm member 24 (direction indicated by dotted line R with arrow). In Figure 9, one end of the open area 240h (open area starting point 240h) is indicated by line 5 S (line connecting the open area starting point 240h and the center point of permanent magnet 5).

The opening angle of open area 240h is 60 degrees in Figure 9. In other words, open area 240h is positioned from one end upwards (starting point of open area 240h) to a clockwise rotated point by 60 degrees. from there.

Also, in support 24h, its periphery, including open area 240h, is trimmed to form an upwardly sloping right-hand portion C1. The inclination angle of the inclined portion Cl is 28 degrees with respect to the vertical geometry axis (not shown) in figure 9.

As evident from figures 9 and 10, the second permanent magnet 5 takes the form of a cylinder whose outside diameter is equal to the inside diameter of the support 24h. With respect to the polarities of the second permanent magnet 5, considering that it is vertically divided into two equal parts along the axial center of the cylinder, one half is pole S (5S: left in figure 9) and the other half is pole N (5N: right in figure 9).

Here the plane divided into two equal parts of the second permanent magnet 5 is orthogonal to line 5 S indicating that the starting point of the open area 240h and the "plane divided into two equal parts" is inclined by 15 degrees with respect to the vertical axis. (not shown).

The support Ilh for supporting the third permanent magnet 6 takes the form of a cylinder with its bottom closed and part of the cylinder periphery is open (it has an open area 10h at the periphery).

In Figure 9, one end of the open area IlOh (or open area starting point 11 Oh) is in a forward position by angle σ 2 (15 degrees in the example shown here) downward in Figure 9 from an extension (which passes the center point of the third permanent magnet 6) of line 24Lc of arm member 24, or rotated clockwise by angle σ2 of extension of line 24Lc.

In Figure 9, one end of the open area 1 10h (or open area starting point 11 Oh) is expressed by lines 6S (line connecting the open area starting point 1 10h and the center point of permanent magnet 6).

The open area 11 Oh is positioned from above one end or line 5 S to a point rotated clockwise by an opening angle thereof. The opening angle is 60 degrees in the example in figure 9.

The open area 11H is trimmed to form a sloping portion C2. The inclined portion C2 is inclined 28 degrees vertically in Figure 9 in the example shown here.

The third permanent magnet 6 takes the form of a cylinder whose outside diameter is equal to the inside diameter of the holder 1 lh. With respect to the polarities of the third permanent magnet 6, considering that it is vertically divided into two parts along the central axis of the cylinder, one half is pole S (6S: right in figure 9), and the other half is pole. N (6N: left in figure 9).

The equally divided plane of the third permanent magnet 6 is orthogonal to line 6S (line connecting the starting point of the open area 1 10h and the center point of permanent magnet 6). In the example in Figure 9, the equally divided plane of the third permanent magnet 6 is inclined 15 degrees with respect to the vertical geometry axis (not shown).

Although the second permanent magnet 5 and the third permanent magnet 6 are both cylindrical permanent magnets in the example in Figure 9, they are not limited to cylindrical but can be bar magnets whose cross-section is polygonal.

In the condition shown in Fig. 9, the second permanent magnet 5 and the third permanent magnet 6 are arranged so that their poles S (5S, 6S) are opposite each other.

When the second permanent magnet 5, or arm member 24, moves through line 24Lc in figure 9 from an area above line 24Lc to an area below line 24Lc in figure 9, the open area 240h of bracket 24h and the open area 11 Oh of the bracket Ilh is not fully opposite one another (placed face to face) until the center of the second permanent magnet 5 reaches a predetermined point in the area below the line 24Lc.

Because the magnetic field of the second permanent magnet 5 and the magnetic field of the third permanent magnet 6 are intercepted by support 24h and support 1 lh, they do not interact with each other unless the open area 240h of support 24h and the open area 11 Ohh of the Ilh bracket are completely opposite each other (face to face).

Thus, until the open area 240h of the support 24h and the open area 1010 of the support Ilh are completely opposite each other (placed face to face), the second permanent magnet 5 and the third permanent magnet 6 do not generate a repulsive force due to homopolarity (S poles). Figure 11 shows a condition where the second permanent magnet 5 rotates at a prescribed angle λ in the area below line 25Lc and the open area 240h of the holder 24h and the open area 110h of the holder 11h are completely opposite each other (placed face to face).

In the condition shown in Fig. 11, because the poles S of permanent magnets 5 and 6 are completely opposite each other and permanent magnets 5 and 6 repel each other, a repulsive force F1 is generated. A component force F2 is generated on the second permanent magnet side 5 and component force F2 gives the arm member 24 counter-clockwise torque. Because arm member 24 is fixed to disk member 22, giving torque to arm member 24, rotation of disk member 22 is encouraged.

As explained above, in the structure shown in Figures 8 to 11, because permanent magnets 5 and 6 are covered by the brackets 24h and 11h, until the open area 240h of the bracket 24h and the open area 110h of the bracket 11h are completely in front of the bracket. other (placed face to face), a repulsive force is not generated between permanent magnets 5 and 6, and thus there is no resistance to torque of arm member 24 and rotation of disc member 22.

Then, when the open area 240h of the holder 24h and the open area 110h of the holder 11h are positioned completely opposite each other (placed face to face), a repulsive force is generated between the permanent magnets 5 and 6, but in this condition the repulsive force works to encourage rotation of arm member 24 or rotation of disc member 22.

Figure 12 shows a variation of the structure illustrated in figures 8 to 11.

The variation in figure 12 is different from the structure in figures 8 to 11 in terms of the open areas of the holder and the planes divided into two equal parts of the permanent magnet, resulting in a difference in the effect of encouraging arm rotation 24.

In Figure 12, when the center of the second permanent magnet 5 is on line 24Lc, the open area 240k of the bracket 24k to cover the second permanent magnet 5 and the open area IlOk of the bracket Ilk to cover the third permanent magnet 6 are both , symmetrical with respect to line 24Lc in figure 12, as the geometric axis of symmetry, vertically in figure 12.

Also, the split plane of the second permanent magnet 5 on an S 5 S pole and an N 5N pole is tilted upwards to the left in Figure 12 and similarly the split plane of the third permanent magnet 6 on S pole S 6S and pole N 6N is angled upward to the left in figure 12.

In the second permanent magnet 5, only the N 5N pole is exposed through the open area 240k. On the other hand, in the third permanent magnet 6, mainly the N 6N pole is exposed through the open area 110k, but the S 6S pole is also partially exposed.

In Figure 12, as the second permanent magnet 5 is involved, a repulsive force F3 against the N 6N pole of the third permanent magnet 6 (repulsive force between the magnetic poles 5N and 6N) and an attractive force F4 between the N pole 5N of the second permanent magnet 5 and pole S of the third permanent magnet 6 are generated simultaneously.

The attractive force F4 has a component force F5 in the direction of rotation R and such component force F5 works to rotate the second permanent magnet 5 towards the arrow R. Consequently, the generation of the component force F5 in the direction of the arrow R on the attractive force F4 between the N 5N pole of the second permanent magnet 5 and the S pole of the third permanent magnet 6 leads to the encouragement of rotation of the second permanent magnet 5 in the direction of arrow R.

In addition, when the second permanent magnet 5 moves downward from the position shown in Figure 12 (toward the arrow R: for the direction of rotation), the repulsive force F3 between the N 5N pole and the second permanent magnet 5 and the pole N of the third permanent magnet 6 works so that an effect of encouraging the rotation of the second permanent magnet 5 or arm 24 in the direction of arrow R is obtained, as in the structure seen in figures 9 to 11.

Again in Figure 2, a box type support member 7 is mounted on the upper surface of the middle frame 12 and in the central area through which the pivot axis 21 penetrates, and the bottom of the support member 7 is opened. The upper surface of the support member 7 is a level plane and is parallel to and spaced at a given distance from the lower surface of the disc member 22.

The upper surface of the support member 7 has a through hole that allows the rotating shaft 21 to rotate freely.

A fourth annular permanent magnet 8 is mounted on the back surface of the disc member 22 in a manner to surround the rotation axis 21. On the other hand, a fifth annular permanent magnet 9, almost similar in shape to the fourth permanent magnet 8, It is mounted on the upper surface of the support member 7 in a manner for circling the axis of rotation 21.

Although not clearly shown, the fourth permanent magnet 8 is fitted to the rear (bottom) surface of the disc member 22 by a stainless steel backing (not shown) and the fifth permanent magnet 9 is also fitted to the fixed member 1 by a Stainless steel backing (not shown).

The fourth permanent magnet 8 and the fifth permanent magnet 9 are arranged so that their surfaces facing one another have the same polarity. However, permanent magnets 8 and 9 are spaced at a given distance from each other for ease of attachment and separation.

Because the fourth permanent magnet 8 and the fifth permanent magnet 9 are provided and the fourth permanent magnet 8 and the fifth permanent magnet 9 are arranged opposite each other and their surfaces facing each other have the same polarity, the fourth permanent magnet 8 and the fifth permanent magnet 9 repel each other. This repulsive force works so that the full rotation member 2 floats from the fixed member 1.

As a consequence, the friction caused by the thrust of the weight of the rotating limb 2 on the fixed limb 1 is reduced, which further decreases the loss on the rotary mechanism 100, making it a more efficient rotary mechanism.

In addition, because rotation member 2 initiates rotation based on the Aragon disc principle, an eddy current occurs on the fourth permanent magnet 8. This eddy current works to rotate the fourth permanent magnet 8 or the rotating member 2 .

In summary, once the rotating member 2 is rotated, a force is still exerted that rotates the rotating member 2.

Here, based on the Aragon disc principle, a similar effect is obtained even if the material of the rotating member 2 is changed from aluminum to synthetic resin.

By moving the fifth permanent magnet 9 vertically in Figure 2 by a means of elevator (not shown), the relative distance between the fourth permanent magnet 8 and the fifth permanent magnet 9 can be adjusted without scaling and thus the effect of the Foucault can be adjusted. The rotation speed of the rotating member 2 can also be controlled by providing a means for adjusting the force generated by the eddy current effect and providing another means of attraction, such as a magnet, on the rotating member 2.

The half elevator for the fifth permanent magnet 9 and the attraction means may be activated by a hydraulic means. In the following, a first variation of the embodiment illustrated in Figures 11all will be described with reference to Figures 13 to 16.

Figure 13 is a plan view of the first variation; Fig. 14 is a sectional view taken along Y-Y in Fig. 13; Fig. 15 is an enlarged fragmentary view of that shown in Fig. 13; and Figure 16 is an enlarged fragmentary view of that shown in Figure 14.

In Figure 16, a coil securing clip 11 is mounted on a cover 1 and 1 of the upper frame 11 on the radially outer side of a coil securing clip 11 and a second coil 3B is fitted to the coil securing clip 11f.

In the first variation shown in Figures 13 to 16, by doubling the number of coils, the magnetic repulsive force between the first permanent magnet and coils 3, 3B is increased, thereby improving the torque of the disc member 22. Next , a second variation of the embodiment illustrated in FIGS. 1A will be described with reference to FIG. 17.

Here, a complete rotary mechanism shown in Fig. 17 according to the second variation is represented by reference numeral 101C.

As compared to the embodiment shown in Figs. 1all (Fig. 4 in particular), which has a combination of a coil 3 and a permanent magnet 4 in only one row vertically (Fig. 4), the second variation in Fig. 17 has a combination of a coil 3 and a permanent magnet 4 vertically in two rows in figure 17.

In Figure 17, the size of the coil mounting clamp 1 If fixed on top frame 11 is large vertically in Figure 17, and two coils 3 are fitted on the clamp Ilf vertically in two rows.

In the following, a third variation of the embodiment illustrated in figures 1 all will be described with reference to figure 18.

In figure 18 showing the third variation, a complete rotary mechanism is represented by reference numeral 100C.

The rotary mechanism 100C according to the third variation in figure 18 also has a combination of a coil 3 and a permanent magnet 4 vertically in two rows as the second variation in figure 17. However, while in figure 17 the Permanent coils or magnets are mounted on a single clamp vertically in two rows, the rotary mechanism 100C in figure 18 has two disc members (represented by reference numerals 22, 22C in figure 18).

In figure 18, a horizontal member IlC is provided below the disk member 22 and the horizontal member 1IC is provided as a fixed member parallel to the disk member 22 and the upper frame 11. A hub 20 is fixed below the horizontal member IlCeo second. disk member 22C is fitted to hub 20.

The permanent magnet side retaining clips 23 are fixed not only to the disc member 22, but also to the upper surface of the second disc member 22C and the permanent magnets 4 are mounted to the retaining clips 23.

Coil 3, located on the rear surface of the horizontal member IlC and permanent magnet 4, located on the upper surface of the second disc member 22C, are positioned completely opposite each other as shown in Figure 18, and a repulsive force between the magnetic fields generated by both drives the rotation of the second disk member 22C. The fourth permanent magnet 8 for letting the rotating member 2 float is mounted on the back surface of the second disc member 22C in a manner positioned opposite the fifth permanent magnet 9 to reduce the thrust caused by the weight of the rotating member 2.

The rest of the structure is similar to the embodiment shown in figures 1 to 11.

In the following, a fourth variation of the embodiment illustrated in figures 1a11 will be described with reference to figure 19.

Here, a complete rotary mechanism according to a second embodiment is represented by reference numeral 101D.

As shown in Fig. 19, the rotary mechanism 101D according to the fourth variation or second embodiment in Fig. 19 has a combination of a first permanent magnet 4B and two coils 3, 3B vertically in two rows, while the The first variation (rotary mechanism 100B) in Figures 13 to 16 (see Figure 16 in particular) has a combination of a first permanent magnet 4B and two coils 3, 3B vertically in only one row.

In Figure 19, the coil mounting clips 11f and 111f are mounted on the upper frame (cover Ie) at different radial distances and coils 3, 3 are mounted on each of the fastening clips 11f, 111f vertically in two rows.

A complete rotary mechanism according to the third embodiment is represented by reference numeral 100D in FIG. 20.

As shown in figure 20, the rotary mechanism 100D according to the third embodiment has a combination of a first permanent magnet 4B and two coils 3, 3B vertically in two rows as the second embodiment shown in figure 19

In the third embodiment in figure 20, with respect to a combination of a first permanent magnet 4B and two coils 3, 3B, the upper combination is the same as shown in figure 16.

In order to add a minor combination of a permanent magnet 4B and two coils 3, 3B, in Figure 20, a horizontal member IlC is provided below the disk member 22 and the horizontal member IlC is provided as a fixed member parallel to the member. disc 22 and upper frame 11 as the third variation in figure 18. One hub 20 is fixed below the horizontal member IlC and the second disc member 22C is mounted on the hub 20.

The way the coils are mounted on the horizontal member IlC and the way the permanent magnet is mounted on the second disk member 22C is the same as in the first variation shown in figure 16.

The rest of the structure in the third embodiment in figure 20 is the same as in the first variation in figure 16.

Although not shown, in rotary mechanism 100 according to the first embodiment, rotary mechanism 100B according to the first variation, rotary mechanism 100C according to the third variation, rotary mechanism 101D according to the first embodiment. With the second embodiment, and the rotary mechanism 100D, according to the third embodiment, the complete apparatus may be covered by concrete or a metal plate or a rigid plastic structure such that the air pressure within of the covered space is reduced in order to reduce the air resistance in rotation and thus make it a rotary mechanism with greater rotation efficiency.

In the following, a second embodiment of the present invention will be described with reference to figures 21 and 22.

A complete rotary mechanism according to the second embodiment is represented by reference numeral 100E in figures 21 and 22.

In Figures 21 and 22, the rotary mechanism 100E is thus structured such that the coils 3 and first permanent magnets 4 in the rotary mechanism 100 in Figures 11all are omitted and rotation of the rotating member 2 is maintained only by the magnetic repulsive force between the second permanent magnets 5 fitted to the three arm members 24 of the rotating member 2 and two third permanent magnets 6 fitted to the fixed member 1.

In the second embodiment in figures 21 and 22 also, as in the embodiment in figures 1 to 11, a second permanent magnet 5 is fitted to an arm member 24 of the rotating member 2 by a fixture 24a and a third permanent magnet 6 is fitted to the fixed member 1 by a fixture 11 g.

Although not clearly shown in Figures 21 and 22, the second permanent magnet 5 and the third permanent magnet 6 are provided with a movable cover to adjust the orientation or magnitude of the magnetic force, and the movable cover has the same structure as the brackets. 1h, 24h in figures 8 to 11 and work similarly.

In Figure 21, a fourth permanent magnet (a magnet for letting the rotating member 2 float) 8 is fitted below the disk member 22 on the axis of rotation 21 and a fifth permanent magnet (a magnet for letting the rotating member 2 float) 9 is set below it.

A first sprocket SL is fixed to the rotation axis 21 below the fifth fixed permanent magnet (a magnet to let the rotation member 2 float) 9.

A small motor M for starting the rotation member 2 is mounted on the lower frame 13 of the fixed member 1. A second sprocket S2 is fitted at the tip of the motor output shaft M.

The first sprocket S1 and the second sprocket S2 are engaged by a chain Cn.

As motor M is driven, rotational motion of motor M is transmitted through second sprocket S2, chain Cn and first sprocket S1 to rotate axis 21 to rotate rotation axis 21.

The structure and advantageous effects of the second embodiment in figures 21 and 22, different from those mentioned above, are the same as in the first embodiment in figures 1 to 11.

In the following, a third embodiment will be described with reference to figures 23 and 24.

A complete rotary mechanism according to the third embodiment is represented by the reference numeral 100 in Figures 23 and 24.

The rotary mechanism 100F according to the third embodiment in figures 23 and 24 is applied to the electric generators.

In Figure 23, the fixed member of the rotary mechanism 100 includes: a cylindrical housing 1F; a top cover IFt to cover the upper opening of the box 1F; a base 14F to cover the lower opening of the box 1F; and a room 15F located in the middle of box 1F. A radial bearing 16 is provided in the center of the top cover 1Ft and a thrust bearing 18 is provided in the center of division 15F and the pivot axis 21F is pivoted by the radial bearing 16 and the thrust bearing 18.

A rotor (or disc member) 22F is fixed to an upper portion of the axis of rotation through a hub 20.

An annular magnet mounting member 4B, which is concentric with the axis of rotation 21, is provided over the radially outer rim of the rear surface of the rotor 22F. A plurality of first permanent magnets 4F are fitted all around the inner periphery of the magnet mounting member 14B.

A fourth permanent magnet 8 is located in a radially internal area (central area) of the rear surface of the rotor 22F in a mode for circling the rotational axis 21F.

A plurality of second permanent magnets 5F are fitted at regular intervals in a radially outer area of the upper surface of the rotor 22F in a concentric circumference with the axis of rotation 21 all around the circumference.

A plurality of third permanent magnets 6F are adjusted at regular radially outwardly spaced intervals of the second permanent magnets 5F all around the circumference.

A coil support member 31F for supporting a 3F disc coil for electricity generation is provided in an area between rotor 22F and division 15F. The coil support member 3IF is located at the upper end of a cylindrical portion 15Fc in the center of division 15F. The coil support member 3IF is integrally formed with division 15F.

A movable division 91 is located in the area between the coil support member 3IF and the division 15F. This movable division 91 is thus structured to slide over the inner wall surface of the IF cylindrical housing by a hydraulic means (not shown) while maintaining a liquid tight condition.

In the center of movable division 91, a fifth annular permanent magnet 9 is set in a mode to encircle the axis of rotation 21F. Thus, as the movable division 91 moves vertically in Figure 23, the fifth permanent magnet 9 also moves up and down vertically in Figure 23.

The surfaces of the fourth permanent magnet 8 and the fifth permanent magnet 9, which are situated opposite each other, are thus structured to have the same polarity and to repel each other. Thus, as the fifth permanent magnet 9 is brought closer to the fourth permanent magnet 8, buoyancy is imparted to the rotating member and buoyancy works to lessen the thrust exerted on the thrust bearing 18 and to reduce the drag resistance. rotation.

In the electric generator having the rotary mechanism 100E, according to the second embodiment in figures 21 and 22, the electric generation efficiency can be improved by reducing the resistance that suppresses the rotation.

In the following, a fourth embodiment will be described with reference to figures 25 and 26.

A complete rotary mechanism according to the fourth embodiment is represented by the reference numeral 100 in Figures 25 and 26.

The rotary mechanism 100G according to the fourth embodiment in figures 25 and 26 is applied to an electric generator with a Darius turbine.

In Figure 25, the rotary mechanism 100G includes: a box 1G; a rotation axis 21G disposed in the center of the housing 1G; a fixed cylindrical coil 6G located in a mode for circling the axis of rotation 21G and a Darius turbine 300 which rotates along the axis of rotation 21G.

Figure 26 is a sectional view taken along XX in Figure 25. Although not clearly shown, a 5G spiral groove is formed on the axis of rotation 21G and the groove 5G is magnetically coated and sealed by a cover-like member (not shown).

The upper end of the rotation shaft 21G is pivoted by a bearing (radial bearing, not shown) provided on an upper housing member 11G and the lower end of the rotation shaft 21G is pivoted by a bearing (a combination of a radial bearing and a thrust bearing (not shown) provided over a lower housing member 13G.

In the rotary mechanism 100G thus structured, when a wind force drives the turbine 300, the liquid-magnet-coated spiral slot 5G spirally disposed within the cylindrical coil 6G also rotates and, due to the relative rotational movement of the cylindrical coil 6G and magnet 5G, an induced current is generated (current generating electricity). Because no ferrous metal is used here, which is attracted to the magnet, electricity can easily be generated.

The generation current generated in coil 6G is stored in a battery 400 located at the bottom of box 1G.

Because the 100G rotary mechanism does not use any ferrous metal, if a weak wind rotates the axis of rotation, electricity can be generated.

Also, by duplicating the turbine shaft and pivoting the outer shaft by a bearing and using the thrust for internal rotation, the thrust resistance of the thrust bearing caused by the weight of the turbine 300 can be reduced and the rotation resistance of the thrust bearing. turbine 300 may be substantially reduced. As a consequence, efficiency can be increased as an electricity generator.

In addition, the illustrated embodiments are for illustrative purposes only and the above description is not intended to limit the technical scope of the present invention.
