Description

Manual Generator with Planetary Gears

The present invention relates to a passive generator, and more particularly, to a passive generator for generating high electromotive force by increasing the rotor speed of the generator using a satellite gear.

In recent years, the explosion of portable audio and video devices, portable computers, portable telephones, and the like has caused problems with the power supply of such devices. That is, in order to continuously use such a portable device, it is necessary to continuously supply power, and the conventional disposable battery has a problem of frequent replacement because of limited use time. In addition, for long-term use, it is necessary to prepare several spare batteries, which is inconvenient as well as the cost of purchasing extra batteries.

To compensate for this, a rechargeable battery is used, which also brings various inconveniences. That is, for long time use, a rechargeable battery must be prepared in advance, and in some cases, a convenient battery charging station located in the market can be found and charged, but this is very cumbersome and not easy to use.

Therefore, an object of the present invention is to drive a generator by simply operating a manual generator instead of using a replaceable battery or a rechargeable battery, thereby generating electromotive force and charging the capacitor to be used as a power source.

Figure 3 is a modified embodiment of Figure 2, showing the configuration of a passive generator having a satellite gear in accordance with the present invention. The embodiment of FIG. 3 differs from the embodiment of FIG. 2 in that the sun gear axis and the ring gear axis are used as the same axis 215. In addition, in the embodiment of FIG. 2, the ring gear shaft is attached to the manual wheel 206, but in the embodiment of FIG. 3, the hole of the ring gear and the sun gear is formed by forming a hole in the center of the manual wheel 206. It is through. In addition, a snap ring 211 is attached to the shaft protruding upward of the manual wheel through the hole to prevent the manual wheel and the ring gear from being separated from the apparatus.

Meanwhile, the embodiment of FIG. 3 differs from the embodiment of FIG. 2 in that only holes are formed without forming bearings in the center portion of the fixed plate, that is, the portion through which the ring gear and the sun gear shaft pass. The omission of the bearings of the sun gear shaft and the fixed plate in the embodiment of FIG. 3 is for the convenience of manufacturing the device, the simplification of the structure, and the cost reduction effect.

4 is a diagram illustrating a configuration of a passive generator having a satellite gear according to another embodiment of the present invention. In the drawing, the sun gear shaft 302 and the sun gear 302 are disposed around the manual wheel shaft 301, and the outer gears have a satellite gear 304 geared to interlock with the sun gear. 304 is fixed to the disk-shaped plane of the manual wheel 305, the shaft of which is located thereon, and is interlocked and interlocked with the ring gear 306, which lies on its outside. On the other hand, the ring gear 306 is circular, is fixed to the outer periphery of the fixed plate 307 located below the ring gear, the permanent magnet 310 is fixed to the same axis as the sun gear. When the user rotates the manual wheel 305, the rotational force is transmitted to the satellite gear shaft 308 to move the satellite gear in the direction of rotation of the manual wheel. At this time, since the one side of the satellite gear is geared to the ring gear fixed to the lower fixed plate, the satellite gear moves while rotating itself inside the ring gear. On the other hand, the other side of the satellite gear is geared to the sun gear is geared to the self-rotation of the satellite gear to rotate the sun gear. At this time, as the sun gear is rotated, the lower permanent magnet fixed to the same shaft is rotated. The permanent magnet is disposed above the coil 309 to generate electromotive force in the coil. The electromotive force thus generated is transferred to the outside to be rectified and accumulated, as in the embodiment of FIGS. 2 and 3.

FIG. 5 is a modified embodiment of FIG. 4, showing an embodiment of a passive generator with satellite gears in accordance with the present invention. FIG. The difference between the embodiment of FIG. 5 and the embodiment of FIG. 4 can be said to be the same as the difference between the embodiment of FIG. 3 and the embodiment of FIG. That is, the embodiment of FIG. 5 uses the manual wheel shaft and the sun gear shaft as the same shaft 315 as compared to the embodiment of FIG. 4, removes the bearing formed in the center of the fixed plate 307, and simply opens the hole. It forms and penetrates the manual wheel and sun gear shaft. In addition, a hole is formed in the center of the disc of the manual wheel 305 to pass through the manual wheel and the sun gear shaft. At this time, the snap ring 311 is formed in the manual wheel and the sun gear shaft which protrudes through the central hole so that the manual wheel does not deviate from the apparatus and the upper part of the manual wheel disc.
