Abstract

PURPOSE:To make it possible to smoothly and satisfactorily operate a wind power driven rotary drive mechanism with a high degree of efficiency and to make the mechanism compact, by automatically selection one of input shafts in accordance with the degree of window power. CONSTITUTION:The rotary motion of a first wind power driven rotary shaft 12 is decreased in its rotational speed and is then transmitted to an output shaft 9 by revolu tion of planetary gears 22 through a gear attaching member 11 so that the load exerted to the rotary shaft 12 may be reduced. Accordingly, the rotary shaft 12 may smoothly rotate even though the wind power is lower so that output energy may be obtained from the output shaft 9. Further, during rotation of a second wind power driven rotary shaft 6 by itself, when the load on the working side increases exceeding a predeter mined value, the self-rotation of the rotary shaft 6 is interrupted, but since the rotary shaft 12 is rotated even under low wind power, the transmission of input energy is automatically changed over into the rotary shaft 12 side so that the rotation of the output shaft 9 may be continued. Thus, the output shaft 9 is rotated by the rotary shaft 12 or the rotary shaft 16 as an input shaft which is automatically selected in accordance with the degree of wind power, thereby it is possible to continuously produce output energy.

Description

DETAILED DESCRIPTION OF THE INVENTION (Background of the Invention) The present invention relates to a rotational drive mechanism that rotates using wind power, more specifically, a wind rotation drive mechanism that rotates blades using wind power to obtain output energy. The present invention relates to a wind rotation mechanism suitable for driving wind power generators, etc.

Wind conditions vary depending on the season, climate, weather, and other factors, and are constantly changing.

By the way, various types of rotary drive mechanisms have been developed for wind power generators, but all of these have a wind blade attached to a single shaft, and the blade is rotated by wind power to generate output. This conventional device is configured to obtain energy in five ways, regardless of the strength of the wind (always in the same state,
Since the shaft is rotated by applying wind force to the same blade under the same conditions, there is a loss in efficiency and the equipment becomes large-scale.

(Object of the Invention) The present invention has focused on the above-mentioned points, and the main object of the present invention is to provide a wind rotation drive mechanism that can operate efficiently and smoothly in response to the strength and weakness of wind power, and that can make the device compact. It is.

(Structure of the Invention) In order to achieve the above-mentioned object, the present invention is provided with a blade, and a blade edge turning shaft and a blade separate from the above, are provided in 2 and 2, which are rotatably supported by a fixed housing. A first wind rotary shaft rotatably inserted into the rotary tube shaft and an output shaft connected to the second wind rotary tube shaft are provided, and the rotational motion of the first wind rotary shaft is reduced through a gear reduction mechanism. At the same time, applying the lever principle, the load is transmitted to the output shaft while reducing the load, so that the 1, 1-1 wind power rotation shaft is configured to be rotatable even with a weak wind force, and under weak wind power, the first wind power rotation is When the shaft is a human-powered shaft, the rotational motion of the rotating shaft is transmitted to the output shaft to rotate the output shaft, and the rotational motion of the output shaft is used as output energy. While the rotary tube shaft is directly rotating, the second wind power rotary tube shaft is used as an input shaft, and the direct rotational motion of the rotary tube shaft is transmitted to the output shaft to generate output energy.

That is, to explain the configuration of the present invention with reference to FIGS. (
b) An O2 wind blade 7 is provided on the outer periphery of the end, and the wind blade 7 forms a coaxial line with the internal gear 3, and the end protrudes outside the housing 1 and is rotatably supported by the housing 1. , an output shaft 72 configured to be rotated by the wind force received by the blades 7, and an output shaft positioned on the same axis as the rotary tube shaft 6 and rotatably supported by the housing 1; 9.) A gear mounting body 11 positioned within the housing 1 and fixed to the rotary tube shaft 6 and the output shaft 9, and connected to the rotary tube shaft 6 and the output shaft 9 so as to rotate together. , (e) linked to the end. ? 11 and a wind root 13, the end of which is connected to the rotating tube shaft 6.
A fan IK force rotation shaft 12, which is arranged so as to protrude outward and be rotatably fitted and supported on the rotary tube shaft 6, and is configured to rotate by the wind force received by the O1 wind blade 13; A relay gear 21 fixedly mounted on the first wind rotation shaft 12 in correspondence with the internal gear 3; A planetary gear 22 is mounted and revolves around the outer periphery of the relay gear 21 while rotating. , 1-1 Wind rotation axis 1
29111, but the rotational movement on the shaft side 12 is transmitted to the spear 1.
The rotary motion of the fang 1 wind power rotation shaft 12 and the second wind power rotation tube shaft 60 is transmitted to the output shaft 9 to rotate the output shaft 9.

(Operation of the invention) Next, the operation will be explained. E.1 When the wind rotation shaft 6 rotates, this rotational motion is transmitted to the planetary gear 22 via the relay gear 21, so the planetary gear 22 rotates in the opposite direction to the relay gear 21. When the planetary gear 22 rotates, this gear 22 meshes with the internal gear 3 fixed to the housing 1, so the planetary gear 22 revolves in the opposite direction to the rotation direction, and this revolution movement is transmitted through the gear mounting body 11. Since the power is transmitted to the output shaft 9, the output shaft 9 rotates while being decelerated at a ratio determined by the difference in the number of teeth between the internal gear 3, the relay gear 21, and the planetary gear 22.

In this way, the rotational motion of the first wind power rotation shaft 120 is transmitted to the output shaft 9 with its rotation speed reduced, so that the load on the first wind power rotation shaft 12 is reduced and the rotational motion of the planetary gear 22 is reduced to a gear. The load exerted on the spear IK force rotating shaft 12 through the mounting body 11 is also reduced at the core. Therefore, the first wind rotation shaft 12 rotates smoothly even when the wind force is weak, transmits this rotational motion to the output shaft 9, and
It becomes possible to obtain the rotational motion of as output energy.

Next, since the second wind-powered rotary tube shaft 6 directly transmits the rotational motion of the tube shaft 60 to the output shaft 9 to generate output energy, the tube shaft 6 directly transfers the load from the output shaft 9 side. receive.

Therefore 1. The i-2 wind power rotation tube shaft 6 does not rotate independently unless the wind power becomes stronger in comparison with the spear 1 wind power rotation shaft 12, but when the wind power becomes stronger and reaches a predetermined value, it begins to rotate independently. . When the second wind rotary tube shaft 6 rotates, the rotational motion of the tube shaft 60 is transmitted to the output shaft 9 via the gear attachment 11, rotates the output shaft 9, and obtains output energy.

On the other hand, when the second wind rotary tube shaft 6 rotates, the rotational motion of the tube shaft 6 is transmitted to the planetary gear 22 via the gear attachment 11, so the gear 22 revolves in the same direction as the tube shaft 6. At the same time, due to meshing with the internal gear 3, it rotates in the opposite direction to the revolution. When the loose M gear 22 rotates, this rotational motion is transmitted to the spear IK force rotating shaft 12 through the relay gear 21, so that the shaft 12 is reversely accelerated and rotated at the same ratio as described above. Since the rotational motion of the shaft 1z is not transmitted to the first wind blade 13 side, the shaft 12 and the blade 13 rotate as separate bodies without interfering with each other, just as if they had been separated. .

As mentioned above, while the rotary tube shaft 6 is rotating on its own, the wind force may become weak or it may stop working. If the load from the # side increases to a predetermined value or more, the independent rotation of the O2 wind rotary tube shaft 6 will be interrupted, but since the first wind rotary shaft 12 is rotating even in a weak wind, the input energy will be First wind rotation axis 1
The output shaft 9 continues to rotate under the rotational movement of the shaft 12, and when the wind becomes strong, it rotates on its own again.In this way, the output shaft 9 continues to rotate by itself. teeth,
The IK force rotation shaft 12 or the second wind power rotary tube shaft 6, which is automatically selected depending on the strength of the wind force at that time, is rotated as an input shaft to continuously provide an output force.

(Example) Embodiments of the present invention will be described below with reference to the drawings.

Figures 27 to 72 show a wind rotation drive mechanism in which the present invention is applied to drive a wind power generator. In these figures, 1 has a cylindrical chamber 2, and an internal gear 3 is mounted on the inner peripheral wall surface.
The housing 1 of the embodiment is formed into two halves, and both halves are fixed together with the internal gear 3 with screws 4.

The housing 1 is supported by a fixed part, and in the embodiment, the housing 1 is shown fixedly supported on a support base 5. In this case, the housing 1 is horizontally rotatably supported on a support base 5 via a turntable, a bearing mechanism, etc., and a vertical wing is attached to the rear of the generator to be described later, so that the front surface of the housing is protected from wind. Even if they are made to face each other in the direction, it is still possible. 0 6 is the second wind blade 7 fixedly attached to the outer periphery of the end.
In the wind rotating tube shaft, the tube shaft 6 is coaxial with the internal gear 3, and the end portion to which the blades 7 are attached protrudes outside the housing 1, and is rotatably supported in the housing 1 via a bearing 8 or the like. The blades 7 are arranged so as to be rotated by the wind force received by the blades 7. The tube shaft 6 of the embodiment is configured to rotate counterclockwise.

Reference numeral 9 denotes an output shaft located on the same front as the rotary tube shaft 6 and rotatably supported by the housing 1 via a metal 10, etc.; 11 is positioned within the housing 1 and connects the rotary tube shaft 6 and the output shaft. The rotating tube shaft 6 and the output shaft 9 are connected by the gear mounting body 11, and are configured to rotate together.

12 was connected to the end. 1?1 1st wind power 13
A first wind rotation shaft 12 is provided with the blade 1.
3 protrudes outside the rotary tube shaft 6, and is fitted and supported on the rotary tube shaft 6 via a bearing 14 or the like,
The blades 13 are configured to rotate due to the wind force applied to them. The rotating shaft 12 of the embodiment is configured to rotate counterclockwise similarly to the tube shaft 6. The first wind power rotating shaft 12 and the 3-IK power blades are linked so that the rotational motion on the blade 13 side is transmitted to the shaft 12 side, but the rotational motion on the shaft 12 side is not transmitted to the blade 13 side. In this embodiment, the mounting cylinder 15 is rotatably mounted on the protruding end of the first wind rotation shaft 12 via a metal 16 or the like, and the cylinder 1 is
The second wind blade 13 is fixedly attached to the outer circumferential wall of the shaft 12, and a second chatter 17 is fixedly attached to the end of the shaft 12, and a ratchet 17 is rotatably attached to the mounting cylinder 15.
The ratchet pawl 19 is shown pressed into engagement by a spring 20. As a result, the counterclockwise rotational movement of the mounting cylinder 15 (blade 13) is transmitted to the shaft 2 via the pawl 19 and ratchet 17 to rotate the shaft 12, and the counterclockwise rotational movement of the shaft 12 is transmitted. is configured so as not to be transmitted to the mounting cylinder 15. As mentioned above, in the embodiment, a ratchet mechanism is used as a linking means between the blade 13 and the shaft 12, but this linking means may be replaced with a one-way cam clutch or other mechanism. Although the rotational motion is transmitted to the shaft 12, it would be better if it was configured to prevent reverse input from the shaft 12 side and allow the shaft 12 to rotate freely without putting any load on it.

Reference numeral 21 denotes a relay gear fixedly mounted on the OR1 wind rotation shaft 12 in correspondence with the internal gear 3, and 22 a planetary gear meshed with the relay gear 21 and the internal gear 3, respectively, and rotatably mounted on the gear mounting body 11. The planetary gear 22 now revolves around the outer station of the relay gear 21 while rotating. In the embodiment, the shaft 23 is fixedly mounted on the gear mounting body 11, and the planetary gear 22 is rotatably mounted on the fixed shaft via a bearing 24, etc., but the gear 22 is mounted on the shaft with an identification shaft. , this axis 2
3 may be configured to be rotatably supported and attached to the gear mounting body 11.

Further, in the embodiment, a configuration in which three planetary gears 22 are provided is shown (see the diagonal diagram), but the number of the planetary gears 22 can be increased or decreased as desired.

In the figure, reference numeral 25 designates a generator in which a rotating shaft 26 is integrally fixed to an output shaft 9 by a key 27 or the like, and is fixedly installed at the rear of the housing 1.

The wind rotation drive mechanism of the embodiment is constructed as described above, and its operation etc. will be explained next. The 1st wind blade rotating shaft rotates with a weaker wind force than the 2nd wind rotating pipe shaft 6. Therefore, when the first wind blade 13 rotates (counterclockwise) in response to the wind force, this rotational motion is transmitted to the first wind rotation shaft 12 via the mounting cylinder 15, pawl 19, and ratchet 17. The shaft 12 rotates counterclockwise. When the rotating shaft 12 rotates, this rotational motion is transmitted to the planetary gear 22 via the relay gear 21, so the planetary gear 22 rotates clockwise. When the gear 22 rotates, the gear 22 rotates into the internal gear 3.
The rotational movement of the relay gear 210 is decelerated at a predetermined ratio, and the rotational movement of the relay gear 210 is decelerated at a predetermined ratio, and the rotational movement of the relay gear 210 is transmitted to the output shaft 9 via the gear attachment body 11. The power is transmitted to the output shaft 9 through the reduction mechanism and the lever principle, and the power is transmitted to the output shaft 9.The output energy of the output shaft 9 rotates the generator 250 rotating shaft 26 and generates a generator. 25.

Next, when the wind strength becomes stronger, the O2 wind rotation tube shaft 6 begins to rotate counterclockwise on its own. When the O2 wind rotary tube shaft 6 rotates independently, the rotational movement of the tube shaft 6 is transferred to the gear mounting body 1.
1 to the output shaft 9, the output shaft 9 rotates at the same speed as the tube shaft 6, and the output energy of this output shaft drives the generator.

On the other hand, when the second wind rotary tube shaft 6 rotates independently, the rotational motion of the tube shaft 6 is transmitted to the planetary gear 22 via the gear attachment body 11, so that the gear 22 revolves counterclockwise and It rotates clockwise due to engagement with the internal gear 3. When the planetary gear 22 rotates, this rotational motion is transmitted to the wind/air rotation shaft 12 via the relay gear 21.
2 is accelerated at the same rate as the deceleration ratio and rotates counterclockwise, but the rotational movement of the shaft 12 is released at the ratchet part, and the ratchet 17 slides against the pawl 19 while cutting with the blade 13 side. It is released and rotates freely.

As described above, when the wind power becomes weak while the 172 wind power rotary tube shaft 6 is independently rotating, or the resistance from the rotation shaft 26 of the generator 25 increases beyond a predetermined value, the second wind power rotary tube shaft 6 rotates independently. 6's own rotation is relayed, but since the first wind rotating shaft 12 is rotating even in a weak wind, the input energy is automatically switched to the spear 1 wind rotating shaft 12 side, and the input energy is transferred from the rotating shaft 12. The output shaft 9 continues to rotate and supplies output energy in response to the rotational motion of Change.

In this way, the output shaft 9 rotates using the first wind rotary shaft 12 or the second wind rotary tube shaft 6, which is automatically selected depending on the strength of the wind force at that time, as an input shaft, and continuously outputs the output energy. Provided to.

(Effects of the Invention) Since the present invention is configured as described above, according to the present invention,
It is possible to provide a wind rotation drive mechanism that rotates efficiently and smoothly in response to the strength of wind power and can be made compact.
