Description

  The present invention relates to a drive device, and more particularly, to a drive device using an alternating magnetic field.

  An engine that generates thermal energy by combustion in the engine and obtains mechanical energy by the thermal energy is generally called an internal combustion engine.

  Japanese Patent Application Laid-Open No. 10-115207 (Patent Document 1) describes a configuration of an internal combustion engine used for a lawn mower, for example. The internal combustion engine disclosed in Japanese Patent Laid-Open No. 10-115207 has a piston, a cylinder part, a connecting rod, and a crankshaft. In this internal combustion engine, air, fuel, and an oil mixture are burned in a fuel chamber constituted by a piston and a cylinder member. As a result, the piston reciprocates, and the reciprocating motion is converted into the rotational motion of the crankshaft via the connecting rod.

  An internal combustion engine used for an automobile or the like is described in, for example, Japanese Patent Application Laid-Open No. 8-86208 (Patent Document 2).

  However, the internal combustion engines described in JP-A-10-115207 and JP-A-8-86208 generate driving force by burning fossil fuel such as gasoline. By burning fossil fuels, carbon dioxide, nitrogen oxides and sulfur oxides are released into the atmosphere. For example, carbon dioxide released into the atmosphere acts as a greenhouse gas by absorbing a part of infrared rays radiated from the surface of the earth, and has been pointed out as one of the causes of global warming. Nitrogen oxides and sulfur oxides released into the atmosphere change into nitric acid and sulfuric acid when dissolved in the rain, which is one of the causes of acid rain.

That is, each of the plurality of columnar bars is fixed to the bottom 2 b and the lid 3 so as to be sandwiched between the bottom 2 b and the lid 3. Thus, the effective surface area of the inner surface 2c of the 2nd rotary body part 2a becomes large by comprising the 2nd rotary body part 2a by the some columnar stick | rod 2a1-2a3. Therefore, since the area where eddy current is generated can be increased, the second rotating body 2a can be efficiently rotated.

Next, the operation of the driving apparatus 10 according to the first embodiment will be described.
Referring to FIG. 2, when the first rotating body portion 1 a starts to rotate, for example, about the axis line x, the inner surface 2 c of the second rotating body portion 2 a facing the outer surface 1 c of the first rotating body portion 1 a is formed. On the other hand, an alternating magnetic field in which the N pole and the S pole alternately change in time is applied. Since the inner surface 2c of the second rotating body portion 2a is made of a conductor, an eddy current is generated in the conductor constituting the inner surface 2c. When the magnetic field (magnetic flux) increases at a certain position on the inner surface 2c of the second rotating body portion 2a, an eddy current is generated on the inner surface 2c of the second rotating body portion 2a so as to suppress the increase of the magnetic field. A force for rotating the second rotating body 2a at a certain position on the inner surface 2c of the second rotating body 2a by the magnetic field generated by the eddy current and the alternating magnetic field generated by the rotation of the first rotating body 1a. Will occur. The force is estimated to be a repulsive force. Similarly, when the magnetic field generated by the rotation of the first rotating body portion 1a decreases at a certain position on the inner surface 2c of the second rotating body portion 2a, the second rotating body portion 2a is controlled so as to suppress the decrease in the magnetic field. Eddy currents are generated on the inner surface 2c. At a position where the inner surface 2c of the second rotating body portion 2a is located by the magnetic field generated by the eddy current on the inner surface 2c of the second rotating body portion 2a and the alternating magnetic field generated by the rotation of the first rotating body portion 1a. A force for rotating the second rotating body 2a is generated. It is estimated that the force is a suction force.

  For example, when the first rotating body 1a rotates clockwise about the axis x, a vortex generated on the inner surface 2c of the second rotating body 2a due to the magnetic field generated by the rotation of the first rotating body 1a. A magnetic field generated by an electric current is generated. Due to the force of the alternating magnetic field generated by the rotation of the first rotating body part 1a and the magnetic field generated on the inner surface 2c of the second rotating body part 2a, the second rotating body part 2a rotates the first rotating body part 1a. Start rotating as you get caught. When the first rotator 1a rotates clockwise, the second rotator 2a also rotates clockwise. That is, the rotation direction a2 of the second rotator unit 2a is the same as the rotation direction a1 of the first rotator unit 1a. If the 1st rotary body part 1a rotates continuously, the 2nd rotary body part 2a will also rotate continuously in the same direction as the rotation direction of the 1st rotary body part 1a. The rotation axis of the second rotator unit 2a is the same as the rotation axis of the first rotator unit 1a.

  The first rotating body 1a may be rotated by, for example, a motor (not shown), or a rotor such as a propeller connected to the first shaft 1d of the first rotating body 1 is, for example, air. It may be rotated by rotating with a flow of fluid such as a gas or a liquid such as water. In the above configuration, the second rotating body portion 2a rotates as the first rotating body portion 1a rotates.

  Conversely, when the second rotating body portion 2a starts rotating, the magnetic field received by a position on the inner surface 2c of the second rotating body portion 2a relatively changes. In other words, an alternating magnetic field in which the N pole and the S pole alternately change in time is applied to a position on the inner surface 2c of the second rotating body portion 2a. Since the inner surface 2c of the second rotating body portion 2a is made of a conductor, an eddy current is generated in the conductor constituting the inner surface 2c. When the magnetic field (magnetic flux) relatively increases at a certain position on the inner surface 2c of the second rotating body 2a, an eddy current is generated on the inner surface 2c of the second rotating body 2a so as to suppress the increase of the magnetic field. To do.

Next, the operation of the drive device in Embodiment 3 of the present invention will be described.
First, the motor 31 is driven by the motor driver 32 to rotate the screw shaft 41 c of the ball screw 41. By rotating the screw shaft 41c, the ball 41e disposed between the screw shaft 41c and the nut 41b moves along the screw groove formed on the surface of the screw shaft 41c, so that the nut 41b is moved to the screw shaft. It moves along the axial direction of 41c. Thereby, the base 41d disposed on the upper surface of the nut 41b, the first support portion 6a disposed on the base 41d, and the first support portion 6a supported by the first support portion 6a. The rotating body 1 moves along a direction parallel to the axial direction of the screw shaft 41c. Note that the axis of the screw shaft 41c is parallel to the respective rotation axes of the first rotating body portion 1a and the second rotating body portion 2a. For example, when the first rotating body 1a of the first rotating body 1 moves to the left with respect to the second rotating body 2a of the second rotating body 2, the outer surface of the first rotating body 1a and the second rotation The overlapping area with the inner surface 2c of the body part 2a is reduced. When viewed from a direction perpendicular to the axis x of the first rotating body 1a (that is, in the field of view of FIG. 15), the length of the first rotating body 1a along the direction of the axis x of the first rotating body 1a is determined. When the length of a region where the inner surface 2c of the second rotating body portion 2a overlaps the outer surface of the first rotating body portion 1a is X2, the outer surface of the first rotating body portion 1a and the second rotating body are defined as X1. The overlapping area ratio with the inner surface 2c of the part 2a is calculated as X2 / X1 × 100 (%). Referring to FIG. 14, in the first state, first rotating body 1a is completely accommodated inside cylindrical second rotating body 2a. In this case, the overlapping area ratio of the outer surface of the first rotating body portion 1a and the inner surface 2c of the second rotating body portion 2a is 100%. From the first state shown in FIG. 14, when the first rotating body part 1a moves to the left side (slides) away from the second rotating body part 2a, the outer surface of the first rotating body part 1a and the second rotation. It changes so that the overlapping area ratio with the inner surface 2c of the body part 2a may become small, and it will be in the 2nd state shown in FIG. The range of the overlapping area ratio is not particularly limited, and can be freely changed within a range of 0% to 100%.

  On the contrary, the 2nd rotary body part 2a may be comprised so that a movement with respect to the 1st rotary body part 1a is possible. In this case, the 2nd support part 6b which supports the 2nd rotary body 2 may be provided on the base 41d provided on the upper surface of the nut 41b of the ball screw 41. That is, when viewed from the direction perpendicular to the axis, the first rotating body portion 1a and the first rotating body portion 1a and the inner surface 2c of the second rotating body portion 2a are changed so that the overlapping area changes. One of the second rotating body portions 2a may be configured to be movable along the direction of the axis with respect to the other of the first rotating body portion 1a and the second rotating body portion 2a.

  The motor control unit 33 is configured to be able to control the motor driver 32. For example, when the rotational speed of the first rotating body portion 1a is greater than a predetermined value, the motor control unit 33 includes the outer surface of the first rotating body portion 1a and the inner surface 2c of the second rotating body portion 2a. The rotation direction and the number of rotations of the motor 31 are controlled via the motor driver 32 so that the overlapping area ratio of the motor is reduced. On the other hand, when the rotation speed of the first rotating body part 1a becomes smaller than a predetermined value, the motor control unit 33 determines that the outer surface of the first rotating body part 1a and the inner surface 2c of the second rotating body part 2a are The rotation direction and the number of rotations of the motor 31 may be controlled via the motor driver 32 so that the overlapping area ratio with is increased.

  For example, when the driving device 10 is a wind power generator, each of the second rotating body portion 2a and the first rotating body portion 1a rotates when the rotor 8 such as a propeller rotates. Power generation is performed by the generator unit 9 connected to the first rotating body unit 1a via the first shaft unit 1d. For example, when the wind speed is 25 m / sec or higher, the rotation speed of the rotor 8 becomes very high, and the rotation speed of the first rotating body 1a also becomes high. Therefore, when an overcurrent is applied to the coil in the generator unit 9, the coil may burn out and the generator unit 9 may be damaged. Therefore, for example, by the ball screw 41, the first rotating body 1a is moved in the direction of the axis x so that the overlapping area ratio between the outer surface of the first rotating body 1a and the inner surface 2c of the second rotating body 2a is reduced. Move along. Thereby, the rotational speed of the 1st rotary body part 1a is reduced rather than the rotational speed of the 2nd rotary body part 2a by reducing the torque concerning the 1st rotary body part 1a from the 2nd rotary body part 2a. Can do. As a result, it is possible to effectively prevent an overcurrent from being applied to the coil of the generator unit 9. On the other hand, when the wind speed is low, the first rotating body 1a is moved so that the overlapping area ratio between the outer surface of the first rotating body 1a and the inner surface 2c of the second rotating body 2a is increased. Accordingly, the amount of power generated by the generator unit 9 may be increased by increasing the torque applied from the second rotating unit 2a to the first rotating unit 1a.

  In the above description, the motor control unit 33 controls the rotation direction and the number of rotations of the motor 31 via the motor driver 32 based on the rotation speed of the first rotation body unit 1a, so that the first rotation body unit 1a. Although the case where the overlapping area ratio of the outer surface of the second rotating body portion 2a and the inner surface 2c of the second rotating body portion 2a is controlled has been described, the motor control unit 33 can measure the wind speed or the rotor measured by, for example, an anemometer The rotational direction and the rotational speed of the motor 31 may be controlled based on the rotational speed of 8 or the like. For example, according to the wind speed measured by the anemometer, the 1st rotary body part 1a is moved along the axis line x direction, and the outer surface of the 1st rotary body part 1a and the inner surface 2c of the 2nd rotary body part 2a The overlapping area ratio may be controlled. The control mechanism for controlling the overlapping area ratio between the outer surface of the first rotating body part 1a and the inner surface 2c of the second rotating body part 2a is not limited to the wind power generator, but various power generation such as the hydroelectric power generator shown in the second embodiment. Available to the device.

  As described above, the driving device 10 according to the third embodiment is a non-contact power that can transmit the rotational force of the second rotating body 2a to the rotating force of the first rotating body 1a without using a gear. It is a transmission mechanism. By controlling the overlapping area ratio between the outer surface of the first rotating body part 1a and the inner surface 2c of the second rotating body part 2a, there is no rotational torque applied from the second rotating body part 2a to the first rotating body part 1a. It can be changed continuously in stages. That is, the drive device 10 according to Embodiment 3 can be used as a non-contact power transmission mechanism having a continuously variable transmission mechanism that can continuously change the transmission gear ratio.

  Further, when the second rotating body portion 2a is rotated in a state where the first rotating body portion 1a is not inserted into the second rotating body portion 2a, the outer surface of the first rotating body portion 1a and the second surface When the first rotating body portion 1a is inserted into the second rotating body portion 2a so that the overlapping area ratio with the inner surface 2c of the rotating body portion 2a is increased, a brake is applied against the rotation of the second rotating body portion 2a. Is applied, and the rotation speed of the second rotating body 2a is reduced. At this time, electric power is generated by the motor connected to the first rotating body 1a. The 1st rotary body part 1a or the 2nd rotary body part 2a may be driven by charging the storage battery with the electric power generated by the motor and rotating the shaft of the motor using the charged electric power. Thus, the drive device 10 can be used as a mechanical regenerative braking system.

Next, functions and effects of the driving apparatus 10 according to Embodiment 3 will be described.

One of the first rotating body part 1a and the second rotating body part 2a moves along the direction of the axis x with respect to the other of the first rotating body part 1a and the second rotating body part 2a. It is configured to be possible. Thereby, the driving force transmitted to the other of the 1st rotary body part 1a and the 2nd rotary body part 2a from one of the 1st rotary body part 1a and the 2nd rotary body part 2a can be changed continuously.

  Further, according to the driving apparatus 10 according to the third embodiment, the rotor 8 provided on one of the first rotating body part 1a and the second rotating body part 2a, and the first rotating body part 1a and the second rotating body part. And a generator unit 9 for converting the energy of the other rotational motion of 2a into electric energy.
