回転方向と同一方向に回転する。First, the band brake 14i is activated and the annular internal gear 10
When the input shaft 1 is fixed and the input shaft 1 is rotated once by a prime mover (not shown), the eccentric shaft 1a also rotates together, and the external gear 5, that is, the planetary gear 2, is rotated by n, which is the difference in the number of teeth from the annular internal gear 10. It rotates in the direction opposite to the rotation direction of the eccentric shaft 1a. That is, the planetary gear 2 rotates N+e in the direction opposite to the rotational direction of the input shaft 1 for each revolution of the input shaft 1. Assuming that eight ring-shaped internal gears are fixed, the external gear 3, that is, the planetary gear 2, rotates -y in the direction opposite to the rotational direction of the input shaft 1 for each rotation of the input shaft 1. The external gears 3.5 are integrally formed on the planetary gear 2, and the annular internal gear 8'?
f: If set freely, the internal gear 8 rotates in the opposite direction to the rotation direction of the planetary gear 12, and for every 1 rotation of the human power shaft 1, it rotates in the same direction as the rotation direction of the input shaft 1. The output shaft 7 connected to the annular internal gear 8 has a reduction ratio R that is shocking to the average person.

01, operate the 15 band brakes, place the annular internal gear 11, and rotate the human power shaft 1 once.
Similarly, the annular internal gear 8 rotates in the same direction as the rotational direction of the input shaft 1 at the input shaft speed ratio R2.Furthermore, the band brake 15 is deactivated, the band brake 13 is activated, and the annular internal gear 9' (ll- When the input shaft 1 is rotated once while fixed, the annular internal gear 8
is 2-2, that is, -N (N

If the difference n in the number of teeth between LO and 11 and the external gears 3, 4, 5, and 6 that mesh with each other is 2, the tooth profile of each gear needs to be arc-shaped, but if the difference n in the number of teeth is 3. In the above case, tooth shapes of each gear other than arc-shaped can also be used. In addition, in this embodiment, there are four pairs of external gears and an annular internal gear that meshes with the external gears to create a multi-speed reduction device capable of three-speed deceleration, but with three pairs, two-speed deceleration is possible. Alternatively, it may be a multi-speed reduction gear that can reduce the speed in four or more speeds by having five or more pairs.

ができる。As described above, the multi-speed reduction gear of the present invention includes three or more external gears formed on a planetary gear, and one annular internal gear for each of the external gears. bite together,
One of the annular internal gears is used as an output member that is connected to the γ output shaft, and the other annular internal gears are used as brake members that are alternately connected to the brake, so there is no need to use multiple clutches as in the past. Both have the advantage of being simple in structure and inexpensive, and also capable of providing reverse speed reduction. Further, by opening all the brake members, power transmission from the input shaft to the output shaft can be easily interrupted, and the output shaft can be freely rotated.
