Description

  The present invention relates to a rotational power generation device that can continuously generate a stable rotational force by a predetermined lever acting force and can be used as a drive source for a generator, an engine, or the like.

  Conventionally, as this type of rotational power generator, there is a technique for generating rotational power by controlling a magnetic field applied from the outside as disclosed in, for example, Patent Document 1. That is, this includes a container main body that contains a magnetic fluid and a non-magnetic fluid having different specific gravities, and a flow resistance portion that is provided on the inner surface of the container main body and is resistant to the flow of the magnetic fluid and the non-magnetic fluid. The magnetic fluid is affected by the magnetic field by applying a magnetic field from the outside in the container body, so that the magnetic fluid and the non-magnetic fluid flow inside the container body. And a rotational force arises in a container main body because a flow resistance part becomes resistance with respect to this flow. On the other hand, by removing the magnetic field, the magnetic fluid and the non-magnetic fluid are returned to the state separated by the specific gravity difference. Therefore, by repeating this operation, a rotational force can be intermittently generated in the container body.

  Further, as disclosed in Patent Document 2, the shape memory alloy is continuously deformed by alternately heating and cooling the shape memory alloy, and the movable member is moved along with the deformation of the shape memory alloy. There are a drive device characterized by the above, a rotary power generation device that generates rotational power by the drive device, and a generator that generates electric power using the rotational power generated by the rotary power generation device. That is, it is made of a hollow shape memory alloy in which a predetermined shape is stored in advance, and when a temperature higher than the transformation temperature of the shape memory alloy is reached, the driving member recovers the predetermined shape, and the temperature of the driving member is the transformation. A deformation means for changing the shape of the drive member to a shape different from the predetermined shape when the temperature is lower than the temperature; a heating means for heating the drive member to a temperature higher than the transformation temperature; and the drive A cooling unit that cools the member to a temperature lower than the transformation temperature; and a movable member that is moved as the shape of the driving member is changed, and the heating unit and the cooling unit include: In this technique, the shape of the drive member is changed by alternately heating and cooling the drive member to move the movable member.

  However, in such a conventional technique, as shown in the technique of Patent Document 1, magnetic fluid and non-magnetic fluid having different specific gravity are used, or as shown in the technique of Patent Document 2, heating and cooling are alternately performed. Since a shape memory alloy for obtaining power by continuously deforming is used, the apparatus itself becomes very complicated and expensive. In addition, since such magnetic field control and temperature control are required to have sustained accuracy, there is a problem that it is difficult to always obtain stable rotational power for a long time.

  Therefore, the present invention was created in view of the existing circumstances as described above, and does not require magnetic field control, temperature control, etc., and has a pure mechanical configuration, so that rotational power that is always stable over a long period of time. An object of the present invention is to provide a simple and low-cost rotational power generator capable of obtaining the above.

The drive gear 5, the drive-side sprocket 6 that rotates coaxially with the drive gear 5, and the drive-side sprocket 6 are wound around the outer periphery of each of the adjacent two drive-side sprockets 6. Those comprising an endless chain 7 which is wound hooked to the output sprocket 4 hauled inwardly from the position.
Further, the accelerator plate 1 can be provided with lever action force by a plurality of force points.

In the rotational power generating device according to the present invention configured as described above, a moment of a predetermined force, such as a linear spring tension, acts on the accelerator plate 1 as an lever acting force, so that each drive gear 5 The shaft (5a) serves as an action point to rotate the output gear 3. At the same time, the rotational force of each drive gear 5 is intensively transmitted to the central output gear 3 by the endless chain 7. In this way, it becomes a drive source for obtaining output from the output gear 3 or the endless chain 7.
That is, the traction force due to the spring tension is efficiently converted into the rotational force of the output gear 3 by each drive gear 5 and the endless chain 7.
The moment of the predetermined force as the lever acting force acting on the plurality of power points of the accelerator plate 1 makes the one-way rotation of the output gear 3 through the roller clutch 9 smooth.

  According to the present invention, there is provided a simple and low-cost rotational power generator that can obtain a rotational power that is always stable over a long period of time with a pure mechanical configuration without requiring magnetic field control, temperature control, or the like. can do.

  That is, this is because the present invention includes a central shaft 2 fixed to the base base plate P, an accelerator plate 1 supported by the central shaft 2 to which a predetermined lever acting force is applied, and a roller clutch 9 on the central shaft 2. Through which the output gear 3 is supported so as to be rotatable in one direction, the output side sprocket 4 which is rotatably supported by the central shaft 2 and is fixed to the output gear 3, and the output gear 3. A plurality of drive gears 5 rotatably mounted on the accelerator plate 1 around the gear 3, a drive side sprocket 6 that rotates coaxially with the drive gear 5, and the outer circumference of each of the drive side sprockets 6 This is because it is provided with an endless chain 7 that is looped around and is pulled inward from an intermediate position between two adjacent drive-side sprockets 6 and hooked around the output-side sprocket 4. . As a result, a moment of a predetermined force due to, for example, linear spring tension or the like acts on the accelerator plate 1 as a lever acting force, so that the meshing positions of the drive gears 5 and the output gears 3 are equal positions around the output gears 3. Both serve as a point of action to smoothly rotate the output gear 3. At the same time, the rotational force of each drive gear 5 can be intensively transmitted to the center output gear 3 by the endless chain 7, so that stable and continuous rotational power can be easily generated, and the accelerator plate 1 The rotational force of the output gear 3 can be easily controlled by the strength of the lever acting force applied to the power.

  Further, since the accelerator plate 1 is provided with the lever action force by a plurality of force points, the rotation of the output gear 3 via the roller clutch 9 can be smoothly performed, and the accelerator plate 1 is sustained and strong in only one direction. Therefore, it is possible to easily and reliably obtain a rotating operation.

  Note that the reference numerals added in the means for solving the above-described problems and the effects of the invention are given for easy reference to the parts showing the components shown in the drawings. The present invention is not limited to the structure / shape indicated by the reference numeral.

It is a front view which shows an example of the rotational power generator in one form for implementing this invention. It is the XX sectional view taken on the line in FIG. It is an expanded sectional view in a central axis part. It is sectional drawing from the Y direction in FIG. 3, and from a Z direction.

  Hereinafter, an embodiment for carrying out the present invention will be described in detail with reference to the drawings. Reference numeral 1 shown in the figure is an accelerator plate constituting the rotational power generator according to the present invention. As shown in FIG. 1, the accelerator plate 1 has, for example, projecting arm portions 1a protruding at symmetrical positions of a hexagonal plate material, and a force point hole portion Q serving as a power point of the lever acting force is formed at each tip side thereof. Has been. Thus, the power point of the accelerator plate 1 is provided in a symmetrical position with respect to the center, and is rotatably supported by the center shaft 2 on the base base plate P which is a non-moving portion. Although not shown, the accelerator plate 1 can be circular, triangular, or other polygonal shape.

  The center axis 2 of the base base plate P is fixed to the base base plate P, has shaft portions with different step diameters, and has a predetermined interval from the base base plate P. An accelerator plate 1, an output gear 3, which will be described later, an output side sprocket 4, and the like are supported. The center shaft 2 is fixed to the base base plate P by being screwed from the back surface of the base base plate P as shown in the figure.

  Further, the accelerator plate 1 is rotatably supported on the central shaft 2 by the central hole portion, and the support is supported by a base 2 by a spacer 2a fitted to the central shaft 2 between the base plate P surface. The plate P is positioned by setting a predetermined interval, and is smoothly rotated with respect to the central axis 2 by a washer 2b fitted to the central axis 2, a liner 2c, a washer 2d in the accelerator plate 1, and the like. (See FIG. 3).

  Further, the center shaft 2 has an output gear 3 that is formed smaller than the accelerator plate 1 so that each corner of the hexagonal accelerator plate 1 can be exposed. These ratchet bars are supported by being rotatable only in one direction via a roller clutch 9 which also serves as a bearing arranged at equal intervals. The output gear 3 is supported on the central shaft 2 so as to be rotatable, and an output-side sprocket 4 having a slightly smaller diameter than the output gear 3 is provided with a liner 4a or the like to set a slight interval. The output gear 3 and the output side sprocket 4 are both rotated at the same time.

  A driving gear 5 having a diameter smaller than that of the output gear 3 is rotated by a rotating shaft 5 a provided on the accelerator plate 1 at each position corresponding to the apex portion which is each corner portion of the hexagonal accelerator plate 1 at intervals of 60 °. It is supported as possible. In this way, a total of six drive gears 5 are arranged at intervals of 60 ° along the periphery of the output gear 3, and each of the six drive gears 5 is meshed with the output gear 3. Each of these drive gears 5 is rotatably supported on the rotary shaft 5a, and a drive-side sprocket 6 having a slightly smaller diameter than the drive gear 5 has a liner or the like to set a slight interval. The drive gear 5 and the drive-side sprocket 6 are both coaxially and integrally rotated.

  An endless chain 7 is looped around each of the six drive-side sprockets 6 so as to surround the outer periphery of each of the six drive-side sprockets 6. It is hooked on the output side sprocket 4 and pulled around to the side. That is, the endless chain 7 is wrapped around the output side sprocket 4 so as to be surrounded from the outer side of the accelerator plate 1 in each driving side sprocket 6 and at a part of the endless chain 7. Both the chain 7 and the output side sprocket 4 are rotated. Of course, the number of drive gears 5 is not limited to six as shown in the figure, but may be provided in any number.

In this way, the rotational force of each drive gear 5 is transmitted to the output gear 3 through the output side sprocket 4 by the endless chain 7, and further, the rotation of the output gear 3 rotates the drive gear 5 to the drive side sprocket 6. The torque is transmitted endlessly. The number of teeth in each of the drive gear 5, the output gear 3, the drive side sprocket 6, and the output side sprocket 4 is set as follows, for example, and is rotated synchronously.
Number of teeth of drive gear 5 / number of teeth of output gear 3
= Number of teeth of drive-side sprocket 6 / number of teeth of output-side sprocket 4 For example, the ratio is 1/4.

  Further, the accelerator plate 1 is formed with a protruding arm portion 1a, for example, by protruding outward from the accelerator plate 1 at one corner, and a force point hole portion Q serving as a power point on the tip side of the protruding arm portion 1a. Is formed. For example, one end of a driving spring 8 having a resilient force is applied to the power point hole Q by being biased in a contraction tendency, and the accelerator plate 1 itself is always attached by, for example, FIG. In this manner, the accelerator plate 1 is rotated clockwise, that is, clockwise.

  The drive spring 8 can be hooked on the force application hole Q on each distal end side of the projecting arm portion 1a provided at a symmetrical position on the accelerator plate 1 so as to be in opposite directions. In this way, the respective tensions of the drive springs 8 that are paired on the left and right side urge each tip side of the projecting arm 1a upward or downward as shown in the drawing to rotate each other clockwise. Also good. Further, although not shown in the drawings, the force point hole portion Q is formed at each corner of the accelerator plate 1 formed in a polygonal shape or at a predetermined corner, for example, a corner that is symmetrical with respect to the center of the accelerator plate 1. May be provided and pulled by the drive spring 8.

  As described above, when the accelerator plate 1 is pulled clockwise, for example, by the tension of the drive spring 8 applied to the protruding arm portion 1a, the output gear 3 is engaged with each drive gear so as to cancel the traction force. 5. It is rotated counterclockwise by an endless chain 7 that is looped around each drive-side sprocket 6 and output-side sprocket 4. At this time, since the output gear 3 is supported so as to be rotatable in one direction via the roller clutch 9, the output gear 3 itself can be smoothly rotated only in one direction. If the roller clutch 9 tries to rotate, the roller clutch 9 stops the motor so as not to rotate clockwise.

  Thus, for example, the moment of the predetermined force as the lever acting force acts on the accelerator plate 1 in an oscillating manner by the elastic tension of the drive spring 8, and this action is achieved by the force point hole portion Q in the accelerator plate 1. Becomes the point of action, the meshing position of each drive gear 5 and the output gear 3 is the operating point, and the center position of the accelerator plate 1 is the fulcrum. Thus, the force with respect to the force point of the accelerator plate 1 acts as a lever by the accelerator plate 1 with the center shaft 2 position supporting the output gear 3 as a fulcrum, and the rotation shaft 5a of each drive gear 5 serves as an action point. The output gear 3, the output side sprocket 4, the endless chain 7, and the drive side sprocket 6 are rotated.

  With the configuration described above, when using rotational power, specifically, for example, an output sprocket 10, an output sprocket, etc. are attached to the output gear 3, and an endless chain, belt, etc. attached to the output sprocket 10 are, for example, The generator, the engine, and the like can be operated by being passed over the rotor of the machine, the crankshaft of the engine, and the like. Further, the output gear 3 can be directly connected to an external generator shaft or a propeller shaft for output. Of course, the power source is not limited to the generator or engine drive source, but can be a drive source of another power engine that requires drive power.

  In the figure, reference numeral 11 denotes a brake handle. For example, by pulling the protruding arm portion 1a in a direction opposite to the pulling direction by the drive spring 8 of one of the protruding arm portions 1a, the output gear via the accelerator plate 1 is output. 3 is stopped.

  Next, an example of use and operation of the embodiment configured as described above will be described. For example, when a moment of a predetermined force as a lever acting force is applied to the force point hole portion Q which is the power point of the protruding arm portion 1a of the accelerator plate 1 by the elastic tension of the drive spring 8, the accelerator plate 1, each drive gear The output gear 3 is rotated by using the rotating shaft 5a of 5 as an action point. At the same time, the rotational force of each drive gear 5 is transmitted to the central output gear 3 by each drive-side sprocket 6, endless chain 7, output-side sprocket 4, and the like. At this time, the output gear 3 is rotated only in one direction around the central axis 2 by the roller clutch 9 and the reverse rotation is restricted, so that the output gear 3 is always rotated in a constant direction. It is to be noted that the starting force applied to the accelerator plate 1 can also be based on an appropriate starter driving force.

  Further, since the output gear 3 is pivotally attached to the central shaft 2 by the roller clutch 9, a force is applied to the protruding arm portion 1 a of the accelerator plate 1 counterclockwise by the elastic tension of the drive spring 8. However, since the swing of the accelerator plate 1 itself is restricted, the output gear 3 is allowed to rotate only in the clockwise direction.

  In this way, the central output gear 3 is rotated in one direction by six equal drive gears 5 at symmetrical positions, and at the same time, the rotational force of each drive gear 5 is applied to each drive-side sprocket 6, endless chain 7, and output side. Since it is transmitted to the central output gear 3 by the sprocket 4 or the like, a stable and continuous rotational force can be obtained for the output gear 3 and also the endless chain 7. Moreover, the rotation of the output gear 3 is always stably and efficiently rotated in a constant direction by the roller clutch 9.
