형으로 양끝이 서로 반대방향을 향하도록 두 부분을 꺾어 휘고, 휘어진 부분의 내각이 90°이상 되는 동각을 가진 일체이고, 다른 팔은

형으로 된 반팔(7)과 반팔(7-1)을 파이프(8) 속에 삽입하여 구성하고, 반팔(7)과 반팔(7-1)의 휘어진 부분의 내각이 한팔(10)의 휘어진 부분 내각과 동각을 이루게 하였다. 또 파이프(8)에 삽입한 반팔(7)과 반팔(7-1)이 이탈하지 않도록 하기 위하여 스프링(9)의 양쪽 끝을 반팔(7)과 반팔(7-1)의 휘어진 부분에 각각 고정하여 반팔(7)과 반팔(7-1)이 서로 잡아당기게 하였다. 또 반팔(7)과 반팔(7-1)을 결합하여 만든 팔의 총 길이가 한팔(10)의 길이보다 약간 짧게 구성한 것이다. 두 개의 팔을 구성한 목적은 도4의 실시도에 도시한 바와 같이 지구축(20)이 항상 한 방향으로 23.5°기울어진 상태로 공전할 수 있게 하려는 것이고, 한팔(10)의 짝을 이루는 다른 팔을 구성함에 있어서 반팔(7)과 반팔(7-1)을 파이프(8)에 삽입하여 구성한 목적은 만약 두 팔의 길이가 약간의 편차만 생겨도 두 팔이 공전모터(4)에 의해 회전할 때 원만하게 회전할 수 없기 때문에 두 팔 중 하나는 그 길이가 자유롭게 신축하여 회전을 원만하게 하기 위한 것이다.In addition, one arm 10 which carries the rotation motor base 11 in the revolution direction by the power of the idle motor 4, the other arm, the short arm 7, the short arm 7-1, the pipe 8, and the spring 9 In detail the configuration, purpose and operation of the other arm consisting of), one arm (10)

The two ends are bent so that both ends face each other in opposite directions, and the angle of the bent is an integral body with an angle of 90 ° or more.

The short sleeve 7 and the short sleeve 7-1 of the shape are inserted into the pipe 8, and the cabinet of the bent portion of the short sleeve 7 and the short sleeve 7-1 is the bent portion of the arm 10. Equivalent to In addition, both ends of the spring 9 are fixed to the bent portions of the short sleeve 7 and the short sleeve 7-1 so that the short sleeve 7 and the short sleeve 7-1 inserted into the pipe 8 are not separated. The short sleeve 7 and the short sleeve 7-1 were pulled together. In addition, the total length of the arm made by combining the short sleeve (7) and the short sleeve (7-1) is configured to be slightly shorter than the length of one arm (10). The purpose of constructing two arms is to allow the earth axis 20 to revolve in an always tilted state of 23.5 ° in one direction, as shown in the embodiment of FIG. 4, and the other arms that mate with one arm 10. In the construction of the short sleeve (7) and the short sleeve (7-1) inserted into the pipe (8), the purpose is configured if the two arms are rotated by the idle motor (4) even if the length of the two arms only slight deviation Since it cannot rotate smoothly, one of the arms is freely stretched to smooth the rotation.

Also, the power of the 120 rpm rotating motor 12 mounted on the rotating motor base 11 divides the power transmission direction into two directions for rotating the earth 21 and revolving the moon 19. That is, the 60T gear 13 and the 20T gear 13-1 are integrally formed on the rotation axis of the rotating motor 12 to separate and transmit power in the direction of rotating the earth 21 and the direction of revolving the moon 19. By mounting the formed second gear, the 60T gear 13 meshes with the earth gear 16 to rotate the earth 21 directly at 120 rpm, and the 20T gear 13-1 decelerates the gear 17 to reduce the moon ( In order to rotate 19, the second stage gear in which the gear 14 and the gear 14-1 are integrally formed between the rotating motor 12 and the moon 19, and the gear 15 and the gear 15-1 are An integrally formed two-stage gear was mounted.

Referring to the operation of the present invention configured as described above in detail;
When electric power is transmitted through the plug 22, the revolution motor 4 at 1 rpm and the rotation motor 12 at 120 rpm are simultaneously driven, and the gear 5 mounted on the rotation shaft of the revolution motor 4 is one arm. (10) and another arm, that is, a short arm (7) and a short arm (7-1) is inserted into the pipe (8) by rotating the gear (6) and the gear (6-1) fixed to the lower part of the arm composed of one arm ( 10) and the other arm rotate at 1/3 rpm to carry the rotating motor base 11 in the orbital direction of the earth 21, so that the earth mounted on the rotating motor base 11 has a speed of 1/3 rpm. Rotate 1 revolution in 3 minutes.

When describing the power transmission process of the rotating motor 12;
Power is separated by a second gear consisting of a gear 13 and a gear 13-1 mounted on the axis of the rotating motor 12, so that the gear 13 is fixed to the lower portion of the earth shaft 20. To rotate the earth counterclockwise, ie, directly in the direction of rotation of the actual earth, and the gear 13-1 is connected to 60T of the second gear in which the 60T gear 14 and the 20T gear 14-1 are integrally formed. 18T gear 15-1 is decelerated because the 20T gear 14-1 rotates in engagement with 60T of the second gear which is formed integrally with another 60T gear 15 and 18T gear 15-1. The moon gear 17 is driven at 4 rpm, so that the moon 19 rotates 12 revolutions around the earth 21 at 4 rpm for 3 minutes during which the earth 21 revolves once. Since the interlocking gear 17 is not fixed to the earth shaft 20 and is turned in vain, the moon gear 17 rotates regardless of the rotation of the earth shaft 20 to allow the moon 19 to revolve.
