The reverse gears 51 are connected to the circular gear 26. The gears are respectively coupled to the circular gears 45.

  With such a configuration, when the outer rotor 12 rotates in the direction of arrow a (counterclockwise) shown in FIG. 4, the coreless coil body 14 is rotated by the reverse gear 51 in the direction of arrow b (clockwise) shown in FIG. 4. Are reversely rotated (coaxial reversal).

  According to the generator G1 (the same applies to the generator G2), when the windmill portion 112 is rotated in the direction of arrow a shown in FIG. 4 by wind energy, for example, the outer rotor 12 is also rotated in the direction of arrow a. The rotational force of the rotor 12 is transmitted to the reverse gear 51. As a result, the coreless coil body 14 rotates in the direction of the arrow b shown in FIG.

  As a result, a large power generation output corresponding to an increase in the relative speed between the magnets 24 and the coil part 41 is transmitted from the coil part output end 42 of the coreless type coil body 14 to the outside via the brush 43 and the output cable 44. Can be derived.

  More specifically, according to the generator G1, the outer rotor 12 and the coreless coil body 14 are configured to be coaxially reversed only by a simple element called the reverse gear 51 in accordance with the rotation of the wind turbine section 112. Therefore, it is possible to obtain, for example, twice the relative speed between the outer rotor 12 and the coreless coil body 14 as compared with a generator using a normal rotor and stator, and under normal conditions of the same wind energy. It is possible to obtain a power generation output larger than that of a wind power generator.

  Specifically, assuming that the power generation output is 100 at a rotation speed of 100 in a normal generator, the power generation unit 1 according to the first embodiment obtains a power generation output of 100 at a rotation speed of 50. be able to. Or, if the rotational speed is 100, 200 power generation outputs can be obtained.

  The upper generator G2 is connected to the upper vertical support 134 in the upside down structure with the generator G1 described above, and is configured to exhibit the same operations and effects as those of the generator G1 described above.

  Next, the floating bearing portion 151 will be described with reference to FIGS.

  FIG. 5 shows an example of the levitation bearing portion 151. The levitation bearing portion 151 is, for example, a hemisphere at a lower position that is a position that is inwardly lowered from the opening end side of the fixed cylindrical body 153. The buoyancy chamber 161 is formed by fixing and closing the opening end of the cylindrical closing member 162 to the inner peripheral portion of the fixed cylinder 153 by welding or the like.

  In the buoyancy chamber 161, a liquid composed of an antifreeze liquid 163 for generating buoyancy and an oil 164 covering the liquid surface of the antifreeze liquid 163 is stored. The oil 164 covers the surface of the antifreeze liquid 163 to prevent the antifreeze liquid 163 from evaporating.

  The levitation bearing portion 151 is supported in a state in which the upper end portion is connected to a connecting wind turbine shaft 115 b that hangs down from the center of the lower surface of the central rotating body 154, and substantially entirely faces the antifreeze liquid 163 in the buoyancy chamber 161. The outer shape of the float 165 is substantially elliptical, and the closing member 162 is penetrated from the lower end of the float 165 in a liquid-tight state with a sealing member (not shown), for example, and connected to the lower generator G1. The wind turbine shaft 115 is included.

  A large number of bearing steel balls 156 are interposed between the outer peripheral portion of the top of the fixed cylindrical body 153 and the circular inner peripheral portion 154a having a larger diameter than the outer peripheral portion provided in the central rotating body 154. Thus, the central rotating body 154 is supported by a radial bearing structure on the top of the fixed cylindrical body 153 so that the central rotating body 154 can be rotated in the horizontal direction.

  As described above, the central rotating body 154 and the upper generator G2 are connected by the upper windmill shaft 115a, and the rotational force of the central rotating body 154, that is, the rotational force of the windmill unit 112 is used as the upper power generation. It is configured to transmit to the machine G2.

  When the above-described levitation bearing portion 151 is employed, the buoyancy F caused by the antifreeze liquid 163 acts on the float 165 facing the antifreeze liquid 163 in the buoyancy chamber 161.

  At this time, assuming that the load M of the windmill portion 112 acting in the direction of pushing the float 165 vertically downward is set in advance such that buoyancy F> load (thrust load) M, the windmill portion 112 is The floating bearing portion 151 is supported in a state where it floats through the antifreeze liquid 163.

  The radial bearing structure using the steel balls 156 shares the radial load of the wind turbine part 112 including the central rotating body 154, and the radial bearing part 152 is located below the top of the fixed cylinder 153 by a predetermined distance. The radial load of the wind turbine unit 112 is shared at a separated position.

  As a result, the shaft support structure including the levitation bearing portion 151 having a simple structure using the buoyancy chamber 161, the antifreeze liquid 163, and the float 165 described above allows the wind turbine shaft 115 around the wind turbine shaft 115 even in the case of the large and heavy weight wind turbine portion 112. It can be pivoted with high accuracy without rolling and in a stable state with low noise, and can be pivotally supported with its thrust load offset or greatly reduced. The output wind power generator 120 can also be supported.

  FIG. 6 shows a levitation bearing portion 151A which is another example of the levitation bearing portion 151. In this levitation bearing portion 151A, the same elements as those in the case of the levitation bearing portion 151 are denoted by the same reference numerals, Detailed description thereof is omitted.
