Description

Specification

Non-contact rotation transmission device and power generation system

Technical field

[0001] The present invention relates to a non-contact type rotation transmission device suitable for transmitting rotation in a non-contact manner using magnetic force, and a power generation system using the rotation transmission device.

Background art

Conventionally, as this type of non-contact type rotation transmission device, there is a magnetic coupling disclosed in Patent Document 1 below. This magnetic coupling is supported coaxially on the input shaft of rotation via a copper alloy ring force bearing case. Further, the output shaft of the rotation is supported by a bearing supported in the boss portion of the bearing case at the inner end thereof, extends coaxially in the copper alloy ring, and is connected to the load.

[0003] The cylindrical yoke is coaxially supported on the output side shaft in the copper alloy ring, and a plurality of permanent magnets are arranged on the outer peripheral surface of the yoke along the circumferential direction. It is fixed with a gap. Here, each permanent magnet has a gap with respect to the inner peripheral surface of the copper alloy ring, and is positioned in non-contact with the copper alloy ring. For this reason, the magnetic flux of each permanent magnet passes through the inside of the copper alloy ring through the gap.

In such a configuration, when the input side shaft is rotated, the copper alloy ring is rotated, and the magnetic flux in the copper alloy ring is changed to generate an eddy current in the copper alloy ring. The magnetic field induced by the eddy current thus generated acts as a magnetic force on each permanent magnet, and the yoke rotates along with the copper alloy ring together with the output side shaft. Thereby, this rotation is transmitted to the load by the magnetic coupling in the non-contact manner. Patent Document 1: JP 2000-197340 A

Disclosure of the invention

Problems to be solved by the invention

[0005] However, in the magnetic coupling, as described above, since the eddy current generated in the copper alloy ring is used to transmit the rotation, the rotational speed of the input side shaft is low. Because the magnetic field induced by eddy current is insufficient, the output shaft is difficult to rotate. This leads to a problem that the transmission of the message cannot be properly performed.

[0006] Therefore, in order to deal with the above-described problems, the present invention has been devised in the configuration and arrangement of the permanent magnet, and appropriately transmits the rotation including the low rotation speed range that does not depend on the eddy current. It is an object of the present invention to provide a non-contact type rotation transmission device and a power generation system using the rotation transmission device.

Means for solving the problem

A central rotor (50, 60) and a plurality of planetary rotors (70-100, 110-140, 180a, 180b, 190a, 190b, 210a, 210b) arranged along the outer circumference of the central rotor; Connecting means (170a, 170b ゝ 200) for connecting a plurality of planetary rotors so as to rotate together in the same direction,

The central rotor includes a central rotor body (60a) and a plurality of permanent magnets (60b to 60i) provided at intervals along the outer peripheral wall of the central rotor body.

Each of the plurality of planetary rotors has a predetermined distance between the planetary rotor main body (110a to 140a) and a plurality of permanent magnets of the central rotor at intervals along the outer peripheral wall of the planetary rotor main body. A plurality of permanent magnets (110b to 110d, 120b to 120d, 130b to 130d, 1 black to 140d) provided so as to be able to be magnetically attracted or repelled with a gap therebetween.

One of the plurality of planetary rotors is set as an input shaft for rotation, and the axis of the central rotor is set as an output shaft for rotation.

[0008] According to this, when the input shaft rotates, a plurality of planetary rotors rotate in the same direction under the connection by the connecting means, and the central rotor corresponds to each permanent magnet. Each planetary rotor is rotated by being attracted or repelled by each permanent magnet.

[0009] Here, such rotation is caused by the permanent magnets of the central rotor and the permanent magnets of the planetary rotors that are not in contact with each other through the opposing end walls without depending on eddy currents. Since this is achieved by exerting repulsive magnetic action, the rotation can be properly transmitted including the low rotation speed range. [0010] Further, according to the present invention, in the non-contact type rotation transmission device according to claim 1,

The central rotor body is formed with V-shaped grooves (63b) formed at intervals along the outer peripheral wall,

Each planetary rotor is formed with V-shaped grooves (11 lb, 121b, 131b, 141b) formed at intervals along the outer peripheral wall,

Each permanent magnet of the central rotor is formed in a substantially rhomboid columnar shape so as to have both side inclined walls (65) and the other side inclined walls (66) parallel to the both side inclined walls. The permanent magnets of each planetary rotor are arranged on both side inclined walls (113, 123, 133, 143) and on the other side inclined walls (114, 124, 134, 144) parallel to these two side inclined walls, respectively. ) So that it has a substantially rhomboid column shape,

The permanent magnets of the central rotor and each planetary rotor are fitted in the V-shaped grooves of the central rotor and each planetary rotor, respectively, on both side inclined walls.

The outer end of each permanent magnet of the central rotor and the outer end of each permanent magnet of each planetary rotor are cut off from the top formed by the other inclined walls, respectively, so that the end walls (66a, 114a, 12 4a, 134a, 144a).

Accordingly, the permanent magnets of the central rotor and the planetary rotors face each other at the end walls as they rotate. Here, the end wall of the permanent magnet can increase the area density of the lines of magnetic force and can form the lines of magnetic force as perpendicular to the outer surface of the end wall as possible. As a result, the above-described magnetic force between the opposing end walls can be secured satisfactorily, and the operational effect of the invention according to claim 1 can be further improved.

[0012] Further, according to the invention described in claim 3, the present invention provides the contactless rotation transmission device according to claim 1 or 2,

Each planetary rotor has a planetary shaft (70 to 100) that coaxially supports the corresponding planetary rotor body.

The connecting means is composed of timing belts (170a, 170b, 200) for connecting the planetary shafts of the planetary rotors adjacent to each other along the outer periphery of the central rotor of the planetary rotors. And [0013] Thus, by using the timing belt as the connecting means, the same effect as that of the first or second aspect of the invention can be achieved more reliably.

[0014] According to the description of claim 4, the present invention provides the contactless rotation transmission device according to claim 3,

When the permanent magnet of the central rotor is not opposite to the permanent magnet of the planetary rotor, the permanent magnet force of the central rotor is the rotation of the planets closest to the permanent magnets in the direction of rotation. When each permanent magnet of the central rotor is opposed to one permanent magnet of each planetary rotor, the attractive force between these opposing permanent magnets is maximized. However, the sum of the attractive forces between the remaining corresponding permanent magnets of each planetary rotor and the central rotor is slightly larger than the force required to separate the opposed permanent magnets from each other. In addition, each timing belt is connected to each planetary shaft of each planetary rotor, and is characterized in that.

[0015] Thereby, when the permanent magnet of the central rotor faces the end wall of the permanent magnet of the planetary rotor, the force that maximizes the attractive force between the opposed permanent magnets. In addition, the sum of the attractive forces between the remaining corresponding permanent magnets of the central rotor is slightly larger than the force required to separate the opposed permanent magnets from each other.

[0016] Therefore, when each planetary rotor rotates, the total magnetic force of the corresponding permanent magnets of the remaining planetary rotors attracts the remaining corresponding permanent magnets of the central rotor and rotates centrally with this rotation. The child can be easily pulled away from the permanent magnet of the planetary rotor by the permanent magnet and rotate smoothly.

The central rotor rotates in the same direction and is rotated by being attracted or repelled by the permanent magnets of the corresponding planetary rotors by the permanent magnets to rotate the output shaft. Along with this, the rotating power generation means generates power by transmitting the rotation of the rotating body described above by the non-contact type rotation transmission device.

[0021] In such power generation, each permanent magnet of the central rotor and each permanent magnet of each planetary rotor are attracted or repelled without contact with each other through the respective opposing end walls that do not depend on eddy currents. Since it is achieved by exerting the matching magnetic action, it is possible to generate power appropriately including the low rotation speed range.

Here, if a speed increasing means for increasing the speed of at least one of the input side and the output side of the rotation transmitting device is adopted, the rotation power generating means can be used without changing the rotation of the rotating body as it is or by increasing the speed of the rotation. Can communicate to. As a result, it is possible to further improve power generation by effectively utilizing wind power or hydraulic power while achieving the operational effects of the rotation transmission device described above.

[0023] According to the description of claim 6, the present invention provides the power generation system according to claim 5,

[0024] According to this, the permanent magnets of the central rotor and the planetary rotors face each other at the end walls as they rotate. Here, the end wall of the permanent magnet can increase the area density of the lines of magnetic force and can form the lines of magnetic force as perpendicular to the outer surface of the end wall as possible. As a result, it is possible to provide a power generation system in which the above-described magnetic force between the opposing end walls is satisfactorily secured and the operational effect of the invention according to claim 1 can be further improved.

[0026] Thus, by using each timing belt as the connecting means, the same effect as that of the invention of claim 5 or 6 can be achieved more reliably.

[0027] According to the description of claim 8, the present invention provides the power generation system according to claim 7,

When the permanent magnet of the central rotor is not opposite to the permanent magnet of the planetary rotor, the permanent magnet force of the central rotor is the rotation of the planets closest to the permanent magnets in the direction of rotation. When each permanent magnet of the central rotor is opposed to one permanent magnet of each planetary rotor, the attractive force between these opposing permanent magnets is maximized.

[0034] The windmill A is constituted by a propeller type windmill such as a Sabotus type, a Darius type, or a paddle type. The windmill A has an input shaft 20a (described later) of the gearbox B at its support A1. It is erected on this gear box B. The support A1 of the windmill A is supported on a horizontal installation surface L (see FIG. 2) by a plurality of stays (not shown).

[0035] The gear box B is configured by providing an input side bevel gear and an output side bevel gear (not shown!) In a rectangular parallelepiped casing 10. The input-side bevel gear is coaxially supported in the casing 10 on the inner end portion of the input shaft 20a that extends upward from the upper wall 11 of the casing 10 so as to rotate upward.

[0036] Further, the output side bevel gear is positioned so as to be orthogonal to the axis of the input side bevel gear on its axis, and meshes with the input side bevel gear, and the output side bevel gear is The casing 10 is coaxially supported by the inner end portion of the output shaft 2 Ob extending horizontally and rearwardly from the rear wall 12 of the casing 10.

[0043] The central rotor 60 includes a central rotor main body 60a (hereinafter referred to as the rotor main body ⁶ Oa) and eight permanent magnets 60b to 60i as shown in FIG. 1, FIG. 2 or FIG. ing. The rotor body 60a is formed concentrically on the annular wall 61 as shown in FIG. 3, the annular boss 62 concentrically formed on the inner peripheral portion of the annular wall 61, and the outer peripheral portion of the annular wall 61. An annular outer peripheral wall 63 is provided.

The lower right sprocket 190b is coaxially supported by the front extension portion of the planetary shaft 80 from the lower left corner of the front support wall 40b.

Further, the rotation transmission device C has a rear timing belt 200 as shown in FIG. 1. The rear timing belt 200 is mounted on the left and right upper sprockets 210a and 210b. ing. Here, a series of teeth formed in an uneven shape on the inner peripheral wall of the timing belt 200 is sequentially meshed with a series of teeth formed in an uneven shape on the outer peripheral walls of both sprockets 210a and 210b, whereby the timing belt 200 And both sprockets 210a and 210b rotate in the same direction.

In this embodiment, the meshing position between each timing belt 170a, 170b and 200 and each corresponding sprocket 180a, 180b, 190a, 190b, 210a and 210b is determined by the rotation of each planetary rotor 110-140. Accordingly, it is selected to satisfy the following two conditions for smoothly rotating the central rotor 60.

[0093] First, in a state where none of the permanent magnets of the central rotor 60 is opposed to any of the permanent magnets of the planetary rotors 110 to 140, the permanent magnets of the central rotor 60 are The meshing positions are selected so that they are attracted by the permanent magnets of the planetary rotors 110 to 140 located closest to the magnet in the rotational direction.

[0094] Second, when one of the permanent magnets of the central rotor 60 faces one of the permanent magnets of the planetary rotors 110 to 140, the attraction force between these opposed permanent magnets is maximum. The total force of the attractive forces between the remaining corresponding permanent magnets of each planetary rotor and the central rotor 60 is slightly larger than the force required to separate the opposed permanent magnets from each other. The combination position is selected.

The speed increaser D has a large-diameter gear 230 and a small-diameter gear 240 that meshes with the gear 230. The gear 230 has a T-shaped bracket in cross section at its shaft hole portion 231. The central shaft 50 is coaxially fitted and supported via the hollow shaft portion 23 2 of 230a at the intermediate portion on the rear end side of the central shaft 50.

[0096] Here, the bracket 230a is fitted in the hollow shaft portion 232 via the key 232a to the intermediate portion on the rear end side of the central shaft 50, and the front flange portion 223 of the bracket 220a is a gear. It is fixed to the front wall of 230.

Note that the rear end portion of the central shaft 50 is rotatably supported by a pillow type bearing member 250. Further, the bearing member 250 is placed on a box-like table 250a on the installation surface L.

[0098] The small-diameter gear 240 is coaxially supported on the rotating shaft 260 of the AC generator E, and the gear 240 is meshed with the large-diameter gear 230. In the present embodiment, the gear ratio of the gear 240 to the gear 230 is 8.

[0099] The AC generator E also serves as an AC generator such as a three-phase synchronous generator. This AC generator E is driven by the speed increaser D to generate a three-phase AC power. To do.

[0100] In the present embodiment configured as described above, when the windmill A rotates by receiving wind, the windmill A is driven by the gearbox B force input shaft 20a along with the rotation. For this reason, in the gear box B, the input shaft 20a rotates, and accordingly, the input bevel gear, the output bevel gear, and the output shaft 20b rotate. Note that the rotational speed of windmill A is proportional to the wind speed.

[0101] Accordingly, the rotation of the windmill A is transmitted by the gearbox B via the input shaft 20a, the input bevel gear, the output bevel gear and the output shaft 20b, and the coupling 30 according to the wind speed. To the input shaft (planetary axis 90). Here, since the gear ratio of the input side bevel gear to the output side bevel gear in the gear box B is 1, the rotational speed of the output shaft 20b of the gear box B is equal to the rotational speed of the windmill A.

[0102] When the rotation of the windmill A is transmitted to the input shaft of the rotation transmission device C as described above, in the rotation transmission device C, the two planetary rotors 130 and 140 force both sprockets 180b as described above. , 180a and both planetary shafts 90 and 100 are connected with the timing belt 170a as a fitting, so that the sprocket 180b, the planetary shaft 90, the timing belt 170a, the sprocket 180a and the planetary shaft 100 are all in the same direction (for example, , Rotate counterclockwise (illustrated in FIGS. 3 and 4). Accordingly, the rotor bodies and permanent magnets of the planetary rotors 130 and 140 rotate in the counterclockwise direction.

[0103] Further, since the two planetary rotors 140 and 110 are connected with the sprockets 210a and 210a and the two planetary shafts 100 and 70 as described above, the timing belt 200 is connected, so The procket 210a, the planetary shaft 100, the timing belt 200, the sprocket 210b, and the planetary shaft 70 rotate together in the counterclockwise direction. Therefore, the rotor main bodies and the permanent magnets of the planetary rotors 140 and 110 rotate in the clockwise direction.

[0104] Also, as described above, both planetary rotors 110 and 120 are coupled with the sprockets 190a and 190b and the two planetary shafts 70 and 80 with the attachment of the timing belt 170b. The shaft 70, the timing belt 170b, the sprocket 190b, and the planetary shaft 80 all rotate counterclockwise. Therefore, the rotor bodies and the permanent magnets of the planetary rotors 110 and 120 rotate in the clockwise direction.

[0105] As described above, each planetary rotor 110-140 force is connected by the three timing belts 170a, 200, and 170b as described above, so each planetary rotor 110-140 force windmill A rotation Accordingly, both rotate in the counterclockwise direction. Then, the central rotor 60 rotates as follows as the planetary rotors 110 to 140 rotate!

Here, in the stopped state before each planetary rotor 110-140 rotates as described above, for example, the permanent magnet 60b of the central rotor 60 is shown in FIG. 8 at its end wall 66a. In this way, it is assumed that one of the three permanent magnets of the planetary rotor 110, for example, faces the end wall 114a of the permanent magnet 110b.

[0107] At this time, the permanent magnet 60d force of the central rotor 60, two of the three permanent magnets of the planetary rotor 120, f array, and the f¾ of both permanent magnets 120b and 120d. Near the permanent magnet 120d. Further, the permanent magnet 60f of the central rotor 60 is located in close proximity to the permanent magnet 130b between two of the three permanent magnets of the planetary rotor 130, for example, between the permanent magnets 130b and 130c. Shall. In addition, the permanent magnet 60h of the central rotor 60 is located close to the permanent magnet 140c between two of the three permanent magnets of the planetary rotor 140, for example, the permanent magnets 140c and 140d. (See Fig. 8).

[0108] In such a state, as described above, when the permanent magnet 60b of the central rotor 60 faces the end wall 114a of the permanent magnet 110b of the planetary rotor 110! The force that maximizes the attraction force between the magnets The total force of the attraction forces between the planetary rotors 110 to 140 and the remaining corresponding permanent magnets of the central rotor 60 Slightly greater than the force required to separate. [0109] Therefore, when each planetary rotor 110-140 rotates as described above, the total magnetic force of the corresponding permanent magnets of the remaining planetary rotors 120-140 is the remainder of the central rotor 60. The corresponding permanent magnet is attracted, and the central rotor 60 can be easily pulled away from the permanent magnet 110b of the planetary rotor 110 by the permanent magnet 60b, and can smoothly rotate in the clockwise direction shown in FIG.

[0110] With such rotation, as shown in FIG. 9, any permanent magnet of the central rotor 60 faces the shifted permanent magnets of the planetary rotors 110 to 140, and is in a state. Then, the permanent magnet force of the central rotor 60 is attracted by the permanent magnets of the planetary rotors 110 to 140 located closest to the permanent magnets in the rotational direction as described above. Under such suction, the central rotor 60 rotates smoothly in the clockwise direction as the planetary rotors 110 to 140 rotate in the counterclockwise direction (see FIGS. 10 and 11). ). Here, the central rotor 60 makes one eighth rotation with each planetary rotor 110-140 making one rotation.

[0111] Further, such rotation does not depend on the eddy current, and the permanent magnets of the central rotor 60 and the permanent magnets of the planetary rotors 110 to 140 are not in contact with each other through the opposing end walls. This is achieved by demonstrating the magnetic action that interacts with each other, so the rotation speed is low! The rotation can be properly transmitted including the range.

In the rotational state as described above, the eccentric rotor 150 rotates in the clockwise direction in conjunction with the central rotor 60. Here, in the eccentric rotor 150, the axial force of the central shaft 50 is also eccentric by a predetermined amount G in the direction connecting the centers in the width direction of the permanent magnets 150b. For this reason, the angle at which the permanent magnet 150b enters the counter-clockwise direction toward the cross-section arc-shaped surface of the permanent magnet 160b of the rotation promoting body 160, that is, the entry angle at which the two permanent magnets 150b and 160b act magnetically, It changes so as to increase by an angle corresponding to the predetermined amount G. This means that the magnetic force between the permanent magnets 150b and 160b changes so as to increase gradually. As a result, the rotation of the central rotor 60 can be promoted more smoothly.

[0113] When the central rotor 60 rotates as described above, this rotation is increased by a factor of 8 with both gears 230 and 240 by the gearbox D and transmitted to the AC generator E. For this reason, even if the wind speed is low, the AC generator E is driven at a rotational speed corresponding to the wind speed to generate a three-phase AC. Properly generate power.

[0114] Thus, it is possible to provide a wind power generation system that appropriately generates three-phase AC power including a range where the rotational speed is low, while achieving the operational effects of the rotation transmission device described above.

[0115] In the implementation of the present invention, the following various modifications are possible without being limited to the above embodiment.

(1) The AC generator E is not limited to three phases, and may be, for example, a single phase AC generator. Further, instead of the AC generator E, a DC generator may be adopted. According to this, DC power can be generated according to the wind speed.

(2) The present invention may be applied to, for example, a hydroelectric power generation system instead of a wind power generation system. In this case, instead of the wind turbine A and the gear box B, the water turbine is coaxially connected to the input shaft of the rotation transmission device C via the coupling 30, so that the substantially same operation effect as the above embodiment is achieved. AC power is generated by hydropower.

(3) The polarity of the permanent magnets of the central rotor 60 and the permanent magnets of the planetary rotors 110 to 140 may be opposite to the polarity described in the above embodiment. In short, each permanent magnet force of the central rotor 60 may have a polarity that attracts each permanent magnet of each planetary rotor 110-140.

(4) The magnetic pole property of each permanent magnet of the central rotor 60 or each permanent magnet of each planetary rotor 110 to 140 may be a polarity opposite to the polarity described in the above embodiment. In short, each permanent magnet force of the central rotor 60 may have a polarity that repels each permanent magnet of each planetary rotor 110-140.

(5) Instead of each timing belt, a chain may be adopted!

(6) The timing bell 卜 200 may be installed via the sprockets at the rear extension ends of the planetary shafts 80 and 90 instead of the planetary shafts 70 and 100.

(7) The timing belts 170a, 170b, and 200 are all configured in such a configuration that all the planetary shafts 70-: L00 rotate in the same direction without being limited to the configuration described in the above embodiment. Equip each timing belt 170a, 170b and 200!

(8) The center axis 50 may be grasped as a concept included in the central rotor 60, and each planetary axis 70 ~: L00 may be grasped as a concept included in each corresponding planetary rotor 110 ~ 140. Yes.

(9) The speed increaser D may be configured with, for example, both pulleys corresponding to both gears 230 and 240 and a belt fitted to these pulleys instead of the configuration of both gears 230 and 240.

(10) The gear ratio of both bevel gears in gearbox B may be set to 8, and gearbox D may be eliminated.

(11) The input shaft of the rotation transmission device C may be the planetary shaft 120, not limited to the planetary shaft 90. If the gearbox B is installed higher, the input shaft of the rotation transmission device C may be the planetary shaft 70 or 100!

(12) In the above embodiment, instead of the windmill A and the gear box B, the drive motor is connected coaxially to the planetary shaft that is the input shaft of the rotation transmission device C via the force coupling 30 and replaced with the AC generator E. Thus, a rotational load such as a hydraulic pump may be connected coaxially to the central shaft 50 that is the output shaft of the rotation transmission device C via the speed increaser D.

[0116] According to this, the rotation transmission device C can transmit the rotation of the drive motor to the rotation load, and the rotation load can be rotated. Such rotation of the rotation load can be made smooth including the low rotation region under the effect of the rotation transmission device C described in the above embodiment. Therefore, the operation by the rotation of the rotation load can be stably maintained.

[0117] Here, if the speed increaser D is abolished, the rotation transmission device C has a function of decelerating to 1/8. Therefore, the rotational speed of the drive motor is high and the rotational load is low. The rotation transmission device C is suitable as a constant speed reduction device.

(13) The number of permanent magnets of the central rotor 60 and the number of permanent magnets of each of the planetary rotors 110 to 140 described in the above embodiment may be changed as appropriate. By changing in this way, the reduction ratio of rotation transmission device C (ratio of input rotation speed to output rotation speed) is changed to a value other than 1/8.
