Description

[Technical field]

[0001] The present invention relates to a thrust generating method, and more particularly to a thrust generating method for generating thrust by changing the rotational speed of a rotor equipped with a weight. [Background technology]

[0002] Conventionally, various techniques have been proposed for thrust generating devices that utilize rotational motion. For example, Patent Document 1 discloses a method for a self-propelled engine that utilizes inertial kinetic energy due to rotation, in which a moving element is fixed to a rotating ring, the fixed state is released at a specific position, the moving element is received by the main body itself, the moving element is returned to the ring, and the moving element rotates again. Furthermore, Patent Document 2 discloses a device for converting rotational motion into forward linear motion, and discloses a technology for generating a desired thrust by rotating a mass and changing the radius of rotation of the mass at the impact apex.

[0004] As described above, various thrust generating devices have been proposed, but most of them are theoretically incorrect and do not generate thrust. For example, in the engine described in Patent Document 1, it is difficult to realize a method for fixing the mover to the ring, a method for releasing the fixed state, and a method for recovering the mover to the ring. In addition, in the device described in Patent Document 2, the maximum force is generated in the impact driving plate by the conversion of the impact from the impact peak to the impact body, and a thrust acts in the direction of the motion vector induced through the impact body bushing (Fig. 10 attached to Patent Document 2). However, since a thrust due to centrifugal force also acts in the opposite direction of the motion vector, the device vibrates violently and effective thrust cannot be obtained.

[0005] The present invention has been made in view of the above circumstances, and has an object to provide a feasible thrust generating method. [Means for solving the problem]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] An embodiment of the present invention will be described with reference to the drawings. However, the embodiment described below is merely an example, and there is no intention to exclude the application of various modifications and technologies not specified below. That is, the present invention can be implemented by various modifications (combining each embodiment, etc.) as long as the effect of the present invention is exhibited. In addition, in the following description of the drawings, the same or similar parts are represented by the same or similar symbols. The drawings are schematic and do not necessarily match the actual dimensions, ratios, etc. The drawings may also include parts with different dimensional relationships and ratios. In addition, in order to avoid the following description becoming unnecessarily redundant and to facilitate understanding by those skilled in the art, detailed descriptions of already well-known matters and duplicate descriptions of substantially identical configurations may be omitted.

[0015] First Embodiment A first embodiment of the present invention will be described with reference to FIGS. Figures 1 and 2 are schematic explanatory diagrams showing the mechanism of a thrust generating device 100 that realizes the thrust generating method of the present invention according to the first embodiment, and Figures 3 and 4 are schematic cross-sectional views of the thrust generating device 100. Figures 1 and 2 show an outline of the mechanism when the thrust generating device 100 is observed from above.

[0016] The thrust generating device 100 is essentially configured to rotate a gear 11 as a rotating body equipped with a weight 15, and generate a thrust in a direction of higher speed by generating a periodic (pulsating, continuous) change in the rotational speed of the weight 15.

[0017] Gear 10 is an example of another rotating body in the present invention, and is driven to rotate by receiving a driving force via shaft 2a from motor 2, which is a driving source provided inside housing 1. In this embodiment, gear 10 is an eccentric gear, and includes rotation axis 10a that rotates by receiving a driving force from shaft 2a at a position offset from the center of gear 10. In other words, rotation axis 10a is provided at a position that is not constant in distance from the edge of gear 10.

[0018] The gear 11 is an example of a rotating body in the present invention, and the chain 20 is an example of a tension member in the present invention. The gear 11 is wound with the chain 20, and when the gear 10 is driven to rotate, the driving force is transmitted via the chain 20, and the gear 11 rotates around the rotation axis 11a. The gear 11 is fixedly connected to the shaft 4a at the rotation axis 11a, which is the center of rotation, and the shaft 4a is rotatably supported by the support part 4 inside the housing 1.

[0019] In addition, gear 11 is provided with a weight 15. Weight 15 rotates in conjunction with the rotation of gear 11. In the example shown in the figure, weight 15 is attached to shaft 4a which rotates in conjunction with the rotation of gear 11, but weight 15 may be attached in another location as long as it is configured to rotate in conjunction with the rotation of gear 11. The adjustment gear 13 is elastically supported by a support part 3 with a rotation spring inside the housing 1 and a shaft 3a.

[0020] In Figs. 1 and 3, when the gear 10 receives driving force from the motor 2 and rotates counterclockwise, the gear 11 and the weight 15 also rotate counterclockwise via the chain 20. 2 and 4 show the gear 10 in FIGS. 1 and 3 rotated 180 degrees. When the rotational speed of gear 10 is constant, by making gear 10 an eccentric gear, it is possible to change the peripheral speed v of the point of contact of gear 10 with chain 20, i.e., the tangential speed of the circumference of the rotating gear 10.

[0021] In FIG. 1, the peripheral speed v1 of point L1 where gear 10 comes into contact with chain 20 can be expressed as v1=r1ω, where r1 is the distance from rotation axis 10a, which is the center of rotation of gear 10, to point L1, and ω is the angular velocity of rotation. In FIG. 2, the peripheral speed v2 of point L2 where gear 10 comes into contact with chain 20 can be expressed as v2=r2ω, where r2 is the distance from rotation axis 10a, which is the center of rotation of gear 10, to point L2, and ω is the angular velocity of rotation.

[0022] Since the rotational speed of the gear 10 is constant, the angular velocity ω is also constant. Therefore, the peripheral velocity v changes in proportion to the distance r from the rotating shaft 10a to the point L1 or L2 where the chain 20 contacts the rotating shaft 10a. In the examples of Figures 1 and 2, the distance r2 is greater than the distance r1, and the peripheral velocity v2 is greater than the peripheral velocity v1. Therefore, the power transmitted from the gear 10 to the chain 20 is greater in the state of Figure 2 than in the state of Figure 1.

[0023] When moving from the state in Fig. 1 to the state in Fig. 2, the driving force from gear 10 is appropriately transmitted to gear 11 via chain 20, through adjustment gear 13 that is elastically supported via shaft 3a to support part 3 with a rotating spring inside housing 1, and adjustment gear 12 that is connected to adjustment gear 13 at connecting part 14. The power transmitted from chain 20 to gear 11 is also greater in the state up to Fig. 2 than in the state in Fig. 1, and the rotational speed of gear 11 is also greater in the state up to Fig. 2 than in the state in Fig. 1.

[0024] 5 is an explanatory diagram showing the rotation of the gear 10 and the gear 11 equipped with the weight 15. Other members such as the chain 20 are not shown. The diagram shows the state of gear 10 and gear 11 equipped with weight 15 when the rotation angle of gear 10 is 0 degrees, 90 degrees, 180 degrees, and 270 degrees. The state of rotation of gear 10 and gear 11 equipped with weight 15 when the rotation angle is 0 degrees is the same as in FIG. 1, and the state of rotation of gear 10 and gear 11 equipped with weight 15 when the rotation angle is 180 degrees is the same as in FIG. 2. The thickness and length of the arrows show the magnitude of the rotation speed of the gear 11 equipped with the weight 15 at each rotation angle of the gear 10. As shown in the figure, the rotation speed changes continuously.

[0025] In this way, by changing the peripheral speed of the gear 10, specifically, the peripheral speed of the part of the gear 10 that contacts the chain 20, the gear 11 to which power is transmitted via the chain 20 can be continuously changed in rotation speed. The weight 15 attached to the gear 11 also changes its rotation speed in the same way as the gear 11. When the weight 15 rotates, the centrifugal force of the weight 15 acts outward from the center of rotation (rotation shaft 11a) of the gear 11, generating a thrust in the outward direction of the gear 11. While the gear 11 is rotating, the centrifugal force of the weight 15 is always generated in the 360-degree direction of the gear 11, but as the rotation speed of the gear 11 changes periodically, the centrifugal force of the weight 15 also changes periodically. When the rotation speed of the gear 11 is the fastest, the largest centrifugal force is generated. By configuring the gear 11 so that the rotation speed is always the fastest at the same part, a large centrifugal force is always generated in only one direction, and a thrust in that one direction can be obtained. That is, in the example of Figs. 1 to 4, a thrust force is generated in the right direction in the figure.

[0026] The peripheral speed of gear 11 changes once every time gear 10 rotates. Every time gears 10 and 11 rotate, the rotational speeds of gear 11 and weight 15 change periodically (pulsatingly, continuously). This makes it possible to continuously obtain a stable thrust with little vibration toward the outside of gear 11 (in the direction of faster speed).

[0027] In addition, when the rotation speed of the gear 11 equipped with the weight 15 is sufficiently fast and exceeds a predetermined speed, a thrust in the direction of the faster speed can be generated more stably. In the case of the configuration illustrated in the first embodiment, that is, when the rotation speed of the gear 10 is the slowest (when r1 is the smallest) and the weight 15 of the gear 11 is located at the lower left of the gear 11, a thrust in the right direction of the thrust generating device 100 (right direction in the figure) is obtained when the rotation speed of the gear 11 equipped with the weight 15 exceeds a predetermined speed. In FIG. 5, when the rotation angle of the gear 10 is from 0 degrees to 270 degrees, the centrifugal force by the weight 15 becomes the largest, and a thrust in the right direction of the thrust generating device 100 is generated. In addition, the thrust generation direction can be adjusted by shifting the period of the speed change of the weight 15. For example, if the period is shifted by 180 degrees, a thrust in the opposite direction is obtained.

[0028] The thrust generating device 100 can generate an effective thrust by rotating the gear 11 equipped with the weight 15 and continuously applying periodic speed changes to the rotation of the weight 15. Furthermore, by repeatedly varying the rotation speed of the gear 11 equipped with the weight 15, a stable thrust with little fluctuation can be continuously obtained.

[0029] Furthermore, the magnitude of the thrust can be adjusted by adjusting the peripheral speed of the gear 10, specifically, the amount of change in the peripheral speed at the point of contact of the gear 10 with the chain 20, that is, in the example of Figures 1 and 2, the difference between the peripheral speeds v1 and v2. For example, if the amount of change in the peripheral speed is small, the amount of change in the power transmitted from the gear 10 to the chain 20 also becomes small, and the fluctuation in the rotational speed of the gear 11 also becomes small. As a result, the magnitude of the thrust also becomes small.

[0030] In this embodiment, the gear 10 is an eccentric gear with a rotating shaft 10a at a position offset from the center of the gear 10, thereby changing the peripheral speed v of the part of the gear 10 where it comes into contact with the chain 20. However, other configurations may be used as long as the peripheral speed v of the weight 15 can be changed. For example, the gear 10 or the gear 11 may be formed in a non-circular shape. With a non-circular shape, the distance r from the rotating shaft to the part of the gear 10 where it comes into contact with the chain 20 can be changed, and the peripheral speed v can be changed.

[0031] In addition, in this embodiment, gear 10 and gear 11 are configured to have the same size, and gear 11 also rotates once when gear 10 rotates once, but the present invention is not limited to this configuration. Gears 10 and gear 11 may be configured to have different sizes, and the number of rotations of both gears may be different.

[0032] Second Embodiment A second embodiment of the present invention will be described with reference to FIGS. 6A, 6B and 7. FIG. 6A and 6B are schematic explanatory diagrams showing the mechanism of a thrust generating device 300 for realizing a thrust generating method according to a second embodiment of the present invention. The thrust generating device 300 is essentially configured to rotate a gear 31 as a rotating body equipped with a weight 35, and generate a thrust in a direction of higher speed by generating a periodic (pulsating, continuous) change in the rotational speed of the weight 35.

[0033] The gear 30 is, for example, a cylindrical gear. The gear 30 receives a driving force from a motor 32, which is a driving source, via a shaft 32a and is driven to rotate. Gear 31 is, for example, a bevel gear. Specifically, gears are formed radially on the circumference of the left side surface of gear 31 in the figure, and this gear portion is configured to mesh with gear 30. Gear 31 receives a driving force from gear 30 and rotates. Gear 31 has a rotation axis 31a at a position that is not a constant distance from the edge of gear 31. Gear 31 in this embodiment is an eccentric gear, and an example is shown in which rotation axis 31a is provided at a position offset from the center of gear 31.

[0034] FIG. 7 is an explanatory diagram showing the rotation of the gear 31. This figure shows the gears 30 and 31 observed from the right side of FIG. 6A and FIG. 6B, and members other than the gears 30 and 31 are omitted. In the example of this figure, the gear 31 rotates around the rotation axis 31a while meshing with the gear 30 at the point indicated by S in the figure (FIG. 7(A) → FIG. 7(B) → FIG. 7(C)). FIG. 6B (FIG. 7(C)) shows the state in which the gear 31 has rotated 180 degrees from the state shown in FIG. 6A (FIG. 7(A)). When the gear 31 rotates further and rotates 360 degrees, it returns to the state shown in FIG. 6A (FIG. 7(A)).

[0035] Gear 31 includes a weight 35. Specifically, weight 35 is provided on a shaft 34 fixed to gear 31, and weight 35 rotates in conjunction with the rotation of gear 31. Shaft 34 is rotatably supported by a support portion 33 of housing 301.

[0036] When the weight 35 rotates, the centrifugal force of the weight 35 acts outward from the center of rotation (rotation axis 31a) of the gear 31, generating a thrust in the outward direction of the gear 31. While the gear 31 rotates, the centrifugal force of the weight 35 is always generated in the 360-degree direction of the gear 31, but since the gear 31 is an eccentric gear, the centrifugal force of the weight 35 also changes periodically. In other words, the circumferential speed of the rotation of the weight 35 changes. And, when the part S where the gear 31 and the gear 30 mesh is closest to the rotation axis 31a of the gear 31, the rotation speed of the weight 35 becomes the fastest, and the largest centrifugal force is generated. By configuring the rotation speed to always be the fastest at the same point, a large centrifugal force is always generated in only one direction, and a thrust in that one direction can be obtained. That is, in the example of the same figure, a thrust is generated in the downward direction in the figure.

[0037] Every time the gear 31 rotates, the rotational speed of the gear 31 and weight 35 changes periodically (pulsatingly, continuously). This makes it possible to continuously generate a stable thrust with little vibration toward the outside of the gear 31 (in the direction of faster speed). When the rotational speed of the gear 31 is sufficiently fast and reaches or exceeds a predetermined speed, a thrust in the direction of faster speed can be generated more stably.

[0038] The thrust generating device 300 can generate an effective thrust by rotating the gear 31 equipped with the weight 35 and continuously applying periodic speed changes to the rotation of the weight 35. Furthermore, by repeatedly varying the rotation speed of the gear 31 equipped with the weight 35, a stable thrust with little fluctuation can be continuously obtained.

[0039] In this embodiment, the gear 31 is configured as an eccentric gear with the rotation axis 31a at a position offset from the center of the gear 31, thereby periodically changing the centrifugal force caused by the weight 35. However, other configurations are possible as long as the centrifugal force caused by the weight 35 can be periodically changed. For example, the gear 31 may be provided with the rotation axis 31a at a position that is not a constant distance from the edge of the gear 31. The gear 31 may also be formed in a non-circular shape with a rotation axis provided at the center. With a non-circular shape, the distance r from the rotation axis 31a to the point of contact between the gear 31 and the gear 30 can be changed, and the circumferential speed v can be changed.

[0040] Furthermore, since gear 31 receives a driving force from motor 32 via gear 30, the rotation speed of gear 31 can be controlled by motor 32. Therefore, for example, motor 32 may be configured as a stepping motor or the like, and a periodic (pulsating, continuous) driving force may be applied to gear 30 to generate a periodic (pulsating, continuous) change in the rotation speed of gear 31, thereby periodically changing the centrifugal force of weight 35 to obtain thrust. In this case, the rotation axis of gear 31 may be configured at the center of gear 31.

[0041] <Third embodiment> A third embodiment of the present invention will be described with reference to FIG. 8 is a schematic explanatory diagram showing the mechanism of a thrust generating device 400 for realizing a thrust generating method according to a third embodiment of the present invention. In this embodiment, a thrust generating device 400 using a non-circular gear as a rotating body of the present invention will be described. The thrust generating device 400 is essentially configured to rotate a gear 41 as a rotating body equipped with a weight 45, and to generate a thrust in a direction of higher speed by generating a periodic (pulsating, continuous) change in the rotational speed of the weight 45.

[0042] Gear 40 is an example of another rotating body of the present invention, has a rotation axis at a position that is not a constant distance from the edge, and receives a driving force via shaft 42a from motor 42, which is a driving source provided inside housing 401, to rotate. In this embodiment, gear 40 is a noncircular gear formed in a noncircular shape, and receives a driving force from motor 42 via shaft 42a to rotate about rotation axis 40a.

[0043] Gear 41 is an example of a rotating body in the present invention. Gear 41 is a noncircular gear formed in a noncircular shape, and when gear 40 and gear 41 mesh with each other and are driven to rotate, a driving force is transmitted and gear 41 rotates around rotation axis 41a. Gear 41 is fixedly connected to shaft 44a at the rotation axis 41a, which is the center of rotation, and shaft 44a is rotatably supported by support portion 44 inside housing 401.

[0044] In addition, the gear 41 is provided with a weight 45. The weight 45 rotates in conjunction with the rotation of the gear 41. In the example shown in the figure, the weight 45 is attached to the shaft 44a which rotates in conjunction with the rotation of the gear 41, but the weight 45 may be attached in another location as long as it is configured to rotate in conjunction with the rotation of the gear 41.

[0045] Fig. 9 is an explanatory diagram of gears 40 and 41 of the thrust generating device 400. This is a diagram of gears 40 and 41 observed from above in Fig. 8, and other members are omitted from the illustration in order to make it easier to see the meshing structure of gears 40 and 41, which are formed into non-circular gear shapes. When gear 40 receives driving force from motor 42 and rotates clockwise around rotation shaft 40a, gear 41, which meshes with gear 40, receives power from gear 40 and rotates counterclockwise around rotation shaft 41a. Weight 45 also rotates in conjunction with the rotation of gear 41.

[0046] Each time the gear 40 rotates once, the peripheral speed of the gear 41 and the weight 45 changes once. The rotational speeds of the gear 41 and the weight 45 periodically (pulsatingly, continuously) change in speed. This makes it possible to continuously obtain a stable thrust with little vibration toward the outside of the gear 41 (in the direction of higher speed).

[0047] The thrust generating device 400 can generate an effective thrust by rotating the gear 41 equipped with the weight 45 and continuously applying periodic speed changes to the rotation of the weight 45. Furthermore, by repeatedly varying the rotation speed of the gear 41 equipped with the weight 45, a stable thrust with little fluctuation can be continuously obtained. By adjusting the number of teeth of the gears 40 and 41, the rotation speed and the amount of change in the rotation speed can be controlled.

[0048] <Fourth embodiment> The thrust generator 500 according to the fourth embodiment can be configured by combining the thrust generators of any of the above-mentioned embodiments. In this embodiment, an example is described in which two thrust generators 300 according to the second embodiment are combined. Fig. 10 is an explanatory diagram of the thrust generator 500 according to the fourth embodiment. A motor (not shown) provided inside the housing of the thrust generator 300 on the left in Fig. 10 and a motor (not shown) provided inside the housing of the thrust generator 300 on the right in Fig. 10 rotate their weights in opposite directions when viewed from the weight side. As thrust from the thrust generator 500, the left and right thrust generators 300 cancel out the rotation of the housing and generate thrust in the same direction. In other words, a resultant force of thrusts from the two thrust generators 300 can be obtained.

[0049] In addition, the rotating body (including other rotating bodies) in the present invention is not limited to gears and may be, for example, pulleys. Furthermore, the tension member is not limited to chains and may be, for example, a chain, a wire rope, a belt, or a combination of these.

[0050] In each of the above-described embodiments, a configuration has been described in which a speed change in the rotation speed of the weight 15 (35, 45) is imparted to the rotation of the gear 10 (30, 40), but the present invention is not limited to such a configuration. As long as a speed change in the rotation speed of the weight 15 (35, 45) is periodically generated to generate a thrust in one direction, any method may be used to rotate the gear 11 (31, 41), and any method may be used to generate a periodic speed change in the rotation of the weight 15 (35, 45).

[0051] A power source may be directly installed on the gear 11 (31, 41). For example, a power source such as a stepping motor may be directly installed on the gear 11 (31, 41) and the power source may generate a periodic speed change in the rotation of the weight 15 (35, 45), thereby adjusting the centrifugal force of the weight 15 (35, 45) to be maximum in a desired direction, thereby generating thrust. In the thrust generating device 300 of the second embodiment, when a power source such as a stepping motor is directly installed on the gear 31 , the rotation axis 31 a of the gear 31 may be configured at the center of the gear 31 .

[0052] The power source and the motor 2 (32, 42) in each of the above-mentioned embodiments are, for example, a gear motor and external power, or a removable dry battery or rechargeable battery. Anything that can transmit rotational power may be used, for example, a drive device that utilizes an internal combustion engine, an external combustion engine, etc.

[0053] In addition, in each of the above-described embodiments, the weight 15 (35, 45) is attached to the shaft 4a (34, 44a) that rotates in conjunction with the rotation of the gear 11 (31, 41), but the weight 15 (35, 45) may be attached in another location as long as it is configured to rotate in conjunction with the rotation of the gear 11 (31, 41).

[0054] Furthermore, the magnitude of the thrust can be adjusted by adjusting the amount of change in the rotational speed (circumferential speed) of the weight 15 (35, 45), or by adjusting the distance from the rotation axis 11a (31a, 41a) of the gear 11 (31, 41) to the weight 15 (35, 45). For example, the greater the amount of change in the rotational speed (circumferential speed) of the weight 15 (35, 45), the greater the thrust generated. Also, the greater the distance from the rotation axis 11a (31a, 41a) of the gear 11 (31, 41) to the weight 15 (35, 45), the greater the thrust generated. Also, the greater the weight of the weight 15 (35, 45), the greater the thrust generated.

[0055] The configurations of the thrust generating devices 100 to 500 according to the respective embodiments for realizing the thrust generating method of the present invention have been described above. Each embodiment may be implemented alone, or any combination of the embodiments may be implemented. Note that the configurations of the thrust generating devices 100 to 500 described above merely explain the basic essentials of the thrust generating method of the present invention. In other words, the technical scope of the thrust generating method according to the present invention is not limited to the scope described in each of the above-described embodiments, and various modifications or improvements can be made within the scope of the claims. The scope of application of the present invention is not limited to the above-mentioned configurations. The present invention can be widely applied to thrust generation methods that can generate thrust using a rotating body equipped with a weight. [Explanation of symbols]

A thrust generating method for a thrust generating device, which generates a thrust in a direction of increasing speed by rotating a rotor equipped with a weight and causing a periodic speed change in the rotation speed of the weight, comprising the steps of: The rotating body is an eccentric gear having a rotation axis at a position where the distance from the edge of the rotating body is not constant, a driving force applied to the eccentric gear by another gear that meshes with the eccentric gear, the eccentric gear rotates about a rotation axis, and the peripheral speed of rotation of a weight attached to the eccentric gear changes, thereby generating the thrust.

2. A thrust generating method for a thrust generating device, which generates a thrust in a direction of increasing speed by rotating a rotor equipped with a weight and causing a periodic speed change in the rotation speed of the weight, comprising the steps of: the rotating body is a gear having a rotation axis at a position that is not uniformly spaced from the edge, A method for generating thrust, comprising the steps of: rotating a gear about a rotation axis when power is received from another gear that meshes with the gear, thereby changing the peripheral speed of rotation of a weight attached to the gear and generating the thrust.
