It becomes a stretched state. Further, although a positive voltage continues to be applied to the stretchable bodies 5A and 5B, the maximum positive voltage also decreases, and the stretchable body 5A enters a stretched state that is more contracted than the maximum stretched state, and the stretchable body 5
B is in a contracted state that is more extended than the minimum contracted state.0 In addition, a positive voltage is also applied to the stretchable bodies 6A and 6B, and the stretchable body 6A is in a stretched state proportional to the voltage, so that the stretchable body 6

7B, the rotating body 12 is rotated in the direction of the arrow and moved to the position shown in FIG. 3(C). At this time, the elasticity of the buffer rubber 4 allows smooth movement. Then, the center P2 of the movable body 8 begins to move in the opposite direction to the rotation direction of the rotary body 12, and comes to be located diagonally above and to the right of the center PI of the rotary body 12. Further, at time point C in FIG. 4, the maximum positive voltage is applied to the stretchable bodies 6A, 6B, and the negative voltage is applied to the stretchable bodies 5A, 5B, 7A, 7B, so that each stretchable body is Deformed as described above, the movable body 8 is the extensible body 5B.

Return to right position against. In this way, the center P3 of the movable body 8
continues to revolve around the center Pl of the rotating body 12. Furthermore, since the voltage applied to each expandable body is a sinusoidal alternating current voltage with a phase shift, the orbital locus becomes a concentric circle with respect to Pi. In this way, since the inner wall surface 8a of the movable body 8 moves while being in contact with the rotary body 12, the rotary body 12 moves smoothly.
Moreover, it becomes K so that it continues to rotate at a low speed. Further, reverse rotation is also possible by changing the phase of each voltage shown in FIG.

In the space formed by the inner circumferential wall surface of the movable body 15, a rotary body 16, which is fixed to a disc-shaped rotary plate through which the output shaft 10 passes, is rotatably supported by the fixed frame 1. The outer peripheral surface of the rotating body 16 is notched with 11116a over the entire circumference. The teeth 161L notched on the rotating body 16 have the same pitch as the teeth 15m notched on the inner peripheral wall surface of the movable body 15, and the number of teeth is one less than the number of teeth on the movable body 15.

。When a three-phase sinusoidal alternating current voltage as shown in FIG. It revolves in a circular orbit. At this time, the 1915 m notched on the inner peripheral wall surface of the movable body 15 and the tooth 16a notched on the outer peripheral surface of the rotary body 16 mesh with each other, and the movable body 15
When the center of the movable body 16 makes one revolution with respect to the center of the rotary body 16, the rotary body 16 rotates by one tooth in a direction opposite to the direction of revolution of the movable body 15. In this case, teeth 16m notched on the outer circumferential surface of the rotating body 16 are teeth 15a notched on the inner circumferential wall surface of the movable body 15.
This is because the number of teeth is formed at the same pitch as the number of teeth of the movable body 15 by one less than the number of teeth of the movable body 15. By providing teeth on the inner circumferential wall surface of the movable body 15 and the outer circumferential surface of the rotating body 16 in this way, the first embodiment may slip, but the second embodiment does not slip, and the reduction ratio You can also precisely obtain stable low-speed rotation.
しかも、歯数の差を変えることによって減速比をかえる

１枚多く形成されている。FIG. 6 is a partially cutaway front view showing a third embodiment of the rotating machine according to the present invention, and FIG. 7 is a sectional view taken along the line ■--■ in FIG. 6. In the figure, reference numeral 17 denotes a fixed frame body made of a cylindrical magnetic material having a bottom surface.A bearing 1B is mounted at the center of the bottom surface of the fixed frame body, and a coil 19 is wound around the inner peripheral wall surface 17 of the frame body. The salient magnetic poles 17b are provided at six locations at 60° intervals over the inner circumference. A flange 17c is formed inward at the open end of the fixed frame 17, and an II 17d is provided on the inner peripheral surface of the flange 17c over the entire circumference to prevent the movable body 20 from rotating. It is marked. A movable body 20 made of a cylindrical magnetic body with an outwardly formed flange 20m is loosely fitted into the space defined by each salient magnetic pole 17b of the fixed frame 1T so as to be freely swingable. The outer peripheral surface of the flange 20m is provided with 20 teeth over the entire circumference.
b is notched. Further, the inner peripheral wall surface of the movable body 20 is provided with teeth 20d over the entire circumference. In the space formed by the inner circumferential wall surface of the movable body 20, a rotating body 16, which is the same as that in the above embodiment, is mounted on the bearing 1B of the fixed frame body 1T.
It is rotatably supported. The tooth 20d notched on the inner peripheral wall surface of the movable body 20 is the tooth 1 notched on the rotating body 16.
The pitch is the same as that of 5m, and the number of teeth is one more than the number of teeth of the rotating body 16.

Coil 1 of each salient magnetic pole 17b provided at 0° intervals
When a sinusoidal AC voltage with a phase shift of 600 is sequentially applied to 9, each salient magnetic pole 17b is sequentially magnetized, the movable body 20 is attracted to each salient magnetic pole 17b, and the center of the movable body 20 is aligned with the output shaft. It begins to revolve around 10. At this time, the movable body 20 does not rotate because the teeth 20b and 17d engage with each other. Further, as the center of the movable body 20 starts to revolve around the output shaft 10, @20d notched on the inner circumferential wall surface of the movable body 20 and teeth 15& notched on the outer circumferential surface of the rotary body 16 mesh with each other, and the movable body 20 becomes movable. When the center of the body 20 makes one revolution with respect to the center of the rotating body 16, the rotating body 16 rotates by the number of bacteria. In this way, electromagnetic force may be used as a rotation means to rotate the rotating body 16 by operating the movable body 20, and the teeth 20b and 17d may be used to prevent the rotating body 16 from rotating when the movable body 20 moves. Since this is provided, a highly reliable rotation speed can be obtained. It should be noted that the teeth 2Qb and 17d do not necessarily need to be provided on the entire circumference and may be provided on a part of the circumference.In addition, in each of the above-mentioned embodiments, a piezoelectric element and an electromagnet were used to obtain the rotation means, but the invention is not limited to this, and shape memory An alloy, bimetal, etc. may also be used. Furthermore, the present invention is not limited to electrical energy, and thermal energy may be used directly.

クトに設計ができるようになる０As explained above, according to the rotating machine according to the present invention, the center of the movable body revolves around the output shaft of the rotary body to rotate the rotary body, so it is not necessary to use a large number of both wheels as in the conventional case. It is possible to obtain low speed rotation without any problems.In addition, the structure is simpler, which reduces manufacturing costs9 and allows for a more compact design0
