本発明は高変速比に速度変換するために使用される遊星
歯車装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a planetary gear system used for speed conversion to high transmission ratios.

Figures 3 and 4 are conventional devices for speeding up speed.
There is a speed conversion device using planetary gears as shown in the figure. In this case, a high speed shaft 1 rotated by a drive source such as a motor (not shown) rotates a sun gear 2 connected on the same shaft 1. The same sun gear 2 and multiple planetary gears in the ash 3.3.8
is rotated around the planetary gear shaft 4.4.4. The planetary gears 3, 3゜3 mesh with the internal gear 5 and rotate the internal gear 5.The internal gear 5 is coaxially connected to a low speed shaft 6.

は出来ない。遊星歯車の数が４個以上の場合も同様の制
限で最大の減速比または増速比が制現される。In this way, the speed converter using the conventional planetary gears has three or more planetary gears 3, 3.3.
r-Since it cancels out the applied force in the direction perpendicular to the axis, it has the advantage of eliminating the need for a high-speed shaft bearing, and is therefore widely used. Further, in order to realize a large speed reduction ratio and speed increase ratio using planetary gears, it is possible to achieve V to some extent by reducing the diameter of the sun gear and increasing the diameter of the planetary gear. However, as shown in Fig. 5, the transmission ratio is limited by the dimension l where the planetary gears 3, 8.3 interfere with each other. It is not possible to increase the diameter of Even when the number of planetary gears is four or more, the maximum reduction ratio or speed increase ratio is achieved with similar restrictions.

正しい保持を要するので運転が非常に複雑になるという
問題があった。Therefore, in order to obtain a high speed reduction ratio (or speed increase ratio), gear devices such as those described above are connected in series, or other types of speed reducers (speed increase @) are combined to achieve a high speed reduction ratio (or speed increase ratio). In such a case, the number of gears increases and becomes expensive, and when combined with a double-row reducer (speed increase @), it is necessary to maintain the correct axis of both shafts, making operation very difficult. The problem was that it was complicated.

It is an object of the present invention to provide a high speed ratio planetary gear device that is inexpensive and does not complicate its operation.
