Abstract

PURPOSE:To store large amount of energy while enabling freely storing/taking- out through different I/O terminals by storing rotary energy into winding force of self-winding molded spring band and utilizing storing capacity in longitudinal direction. CONSTITUTION:Rotation of a wheel 5 where the outer end section 11 of self winding spring 10 wound around a spool 7 is fixed to a portion of circumference is blocked by a stopper click 12 and a ratchet 12' to rotate the spool 7. When removing said click 12, the stored force can be taken out from its shaft 6 through rotation of wheel 5 in arrow direction. Even under provision of input M, it can be taken out as outputs M1, M2. Since said spring 10 has winding resiliency because the winding portion is molded, it is uniform in longitudinal direction to increase the storing amount of force. Upon rotation of wheel 5 in counter-arrow direction, it will function as brake to enable storing of said force in storing direction.

Description

[Detailed Description of the Invention] In general, power storage devices for rotational energy can be thought of chemically as a storage battery or mechanically as a flywheel, but the obstacles are that they are difficult to store for long periods of time and are large in mass. . In addition, elastic coil springs have poor storage capacity, and their use efficiency is extremely low because they gradually increase (or gradually decrease) without averaging within the limits of elasticity. The present invention can store a large amount of energy by storing rotational energy in the unwinding force of a self-winding formed band spring and utilizing its storage ability in the length direction. This allows input and output to be performed freely at any time, and this will be explained in detail using drawings.

A worm 2 is attached to the shaft of a rotational energy source 1 (for example, a windmill).
A worm wheel 3 is provided, the shaft portion 6 of the wheel 5 is rotatably inserted into the shaft 4 of the worm wheel 3, and the spool 7 is rotated along the circumference of the wheel 5.
Attach the rotating arm 9 of the spool shaft 8 to the shaft 4. A belt-shaped self-winding spring 10 formed into a winding type is wound around the spool 7, and the outer end 11 of the self-winding spring 10 is attached to a part of the periphery of the wheel 5, so that the rotational energy source 1 rotates and the worm is generated. 2. When the worm wheel 3, shaft 4, and rotating arm 9 rotate in conjunction with each other, and the spool 7 rotates around the periphery of the wheel 5 in the unmarked direction, the self-winding spring 10 wound around the spool 7 will continue to operate as long as the wheel 5 is stopped. At the periphery of the wheel 5, the wheel 5 is configured to be unrolled.
The rotation of the spool 7 is fixed by the ratchet teeth 12' of the pawl 12, and the spool 7 is rotated. It can be taken out by the shaft part 6, and can be taken out as the output M1 M2 even while the input M is being input. Also, unlike ordinary elastically wound springs, self-winding springs have elasticity due to the formability at the end of the winding, so they are always uniform in the length direction, so the amount of stored force increases in proportion to the length of the strip spring. The performance is not comparable to conventional spring springs.

In addition to the method of storing intermittent input, if the wheel 5 is turned in the opposite direction as an output brake, it becomes a brake and its force can also be stored in the storage direction. Fig. 1 shows an example in which the rotational input is used as a generator, and an example in which it is used in a billboard. Fig. 2 shows an example in which the vibration of a pendulum K and the clutch plate 13 are used to switch to rotation in one direction and store power. In order to put this principle into practice, we have now incorporated it into the differential gear system shown in Figures 3 and 4. The left side gear 16 of the left and right side gears 16 and 16' that mesh with the planetary pinion gears 15 and 15' bearing in the gear case 14 is a hollow shaft, and the right side gear 16' is a through shaft, and both side gear shafts 17 and 17' are the same. The end of the self-winding spring 21 is protruded from the side and is wound around the self-winding spring spool 20 attached to the spool shaft rotating arm shaft flange 18 and the wheel gear flange 19 attached to each of the spool shaft rotating arm shaft flange 18. Attach part 22 to the peripheral edge of the wheel gear flange 19 to form the self-winding spring spool 20.
is designed so that its periphery rotates and revolves around its axis. By extending the side gear shaft 17', which is the mounting shaft of the wheel gear flange 19, and attaching a band brake set 23, the rotation of the wheel gear flange 19 can be freely stopped by pulling the lever 24 with a wire 25. . In addition, the spool shaft rotating arm shaft flange 1
8 has a ratchet and 26 cut into it, and a pawl 27 prevents it from rotating.

Further, a gear case drive gear 28 is attached to transmit the rotation of the power source to the gear case 14, a small gear 29 meshing with this gear, and a large gear 30 attached to its shaft. A balance weight 31 is provided on the spool shaft rotating arm shaft flange 18 to balance the rotation. To explain this mechanism now, as a power source, for example, when the large gear 30 is rotated in conjunction with the hub core of a bicycle wheel, the gear case 14 rotates due to the rotation of the gear case drive gear 28, and the planetary pinion gear 1 attached to it rotates.
A side gear 1616' meshing with 5 15' rotates together with the spool shaft rotating arm shaft flange 18 and wheel gear flange attached to the shaft 17 17'.
19 rotates without shifting, but when the lever 24 of the band brake set 23 is moved and activated by the wire 25, the self-winding spring spool 20 rotates around its periphery from the moment the wheel gear flange 19 stops rotating. Rotate the self-winding spring 21 Wheel gear flange 19
Wrap it around the rim. When the brake of the band brake set 23 is released at any time, the spool shaft rotating arm shaft 18 is prevented from reversing by the ratchet 26 and the pawl 27, so the restoration is performed by the rotation of the wheel gear flange 19. Side gear 16' attached to the shaft
rotates, and the gear case 14 rotates. In either case, the direction of rotation is in the direction of mismarking, and the large gear 30 can always rotate in the same initial direction, so there is a wide range of possible uses, such as using the energy from descending a slope as energy for climbing.

In this way, the present invention can be implemented as a large-scale device such as a car, bicycle, wind power generation, etc., and it is possible to mechanically store all rotational energy for a long period of time. Considering the fact that the output limit, that is, the braking energy can be recovered to the input side, it can be used to intervene in all rotating equipment.
