(A) and (b) are operating states of the urging device. FIG. 4 shows a front view of another preferred embodiment, a rotary drive device of the present invention.

The rotary drive device according to the present invention is characterized in that power can be transmitted efficiently with little power.
Hereinafter, embodiments of a rotary drive device of the present invention will be described with reference to the drawings.

  The rotation drive device 1 shown in FIG. 1 includes a first rotating body 2 and a second rotating body 4 rotatably connected to the first rotating body 2 via a belt 3. In addition, the rotation driving device 1 includes a rotation unit 6 fixed to the center shaft 5 of the first rotation body 2, a rotation adjustment unit 7 connected to the rotation unit 6, and an attachment mounted on the rotation unit 6. The power device 20 is provided. The rotation drive device 1 is installed on a base 11.

  The first rotator 2 and the second rotator 4 are rotatably connected to each other by a belt 3. In particular, the belt winding part 8 of the first rotating body 2 is formed to have a larger diameter than the belt winding part 9 of the second rotating body 2.

  The rotating part 6 is fixed to the center shaft 5, and a holding part 21 for operating an urging device 20 described later is attached to an eccentric part of the rotating part 6.

  The rotation adjustment unit 7 has an adjustment function of rotating the rotation of the rotation unit 6 in a certain direction. The rotation adjusting unit 7 can suitably use a gear mounted on a wheel axle of a bicycle. By attaching the rotation adjusting section 7, the rotation of the rotating section 6 can be efficiently transmitted to the central shaft 5.

  The biasing device 20 further accelerates the rotational force of the rotating unit 6, and includes a holding unit 21 installed in an eccentric state, a first arm unit 22 locked by the holding unit 21, and a first arm unit 22. A second arm 23 loosely attached to the second arm 23 via a connector 24, a case 25 for slidably receiving the second arm 23, and a lower end of the second arm 23 in the case 25. And an urging spring 26 disposed at the second position.

  Next, the operation of the urging device 20 will be described with reference to FIGS. 3 (a) and 3 (b) and FIGS. 4 (a) and 4 (b).

  FIG. 3A shows a state in which the holding unit 21 of the rotating body 6 is located above. At this time, the second arm 23 is located at the upper part, and the biasing spring 26 is accommodated in the case 25 in an extended state.

  FIG. 3B shows a state in which the first rotating body 2 has rotated in the direction of the arrow. At this time, the rotation adjusting unit 7 and the rotating unit 6 rotate, and the holding unit 21 moves downward, and at the same time, the first arm unit 22 and the second arm unit 25 move downward. Thus, the biasing spring 26 in the case 25 is contracted by the second arm 23.

  FIG. 4A illustrates a state in which the first rotating body 2 further rotates in the direction of the arrow, and the holding unit 21 is disposed at the lowest position. At this time, the rotating unit 6 and the rotation adjusting unit 7 further rotate, the holding unit 21 also moves further downward, and at the same time, the first arm unit 22 and the second arm unit 25 move to the lowest position. Thereby, the urging spring 26 in the case 25 is further contracted by the second arm 23.

  FIG. 4B shows a state in which the first rotating body 2 is further rotated in the direction of the arrow. At this time, the holding portion 21 moves upward at the same time as the urging spring 26 in the case portion 25 is extended. At this time, since the rotating unit 6 is connected to the rotation adjusting unit 7 in a free state in a fixed direction, the rotating unit 6 is rotated upward at a higher speed than the rotation adjusting unit 7 by the return force of the urging spring 26. I do. Therefore, power can be transmitted efficiently with little power.

  As another preferred example, as shown in FIG. 2, a fourth rotating body 30 is connected to the center shaft 5 of the first rotating body 2, and the urging device 40 having the above-described structure is attached to the fourth rotating body 30. The provided third rotating body 31 was connected.

  By attaching the urging device 40 to the third rotating body 31 and connecting the fourth rotating body 30 with the belt 32, the fourth rotating body 30 is rotated at high speed with a small force by the urging device 40. Can be. By providing the fifth rotating body 33, the rotating force can be transmitted to another rotating member.

  As another preferred example, as shown in FIG. 5, a generator 12 is provided on a center shaft 10 of the second rotating body 4. As the generator, a dynamo or the like provided in a bicycle is preferably used. Since the generator 12 is provided on the central axis 10 of the second rotating body 4, the rotating force of the second rotating body 4 can be reused as electric power. A power source 13 for rotating the rotary drive device 1 of the present invention is mounted on the second rotating body 4.

  As described above, the rotary driving device 1 of the present invention includes the first rotating body 2 and the second rotating body 4 rotatably connected to the first rotating body 2 via the belt 3. 2 with a rotating unit 6 fixed to the central shaft 5, a rotation adjusting unit 7 connected to the rotating unit 6, and a biasing device 20 attached to the rotating unit 6, with less power. Power can be transmitted efficiently.

  Further, by providing the second rotating body 4 with the generator 12, the rotating force of the second rotating body 4 can be reused as electric power.
