Abstract

PURPOSE:To enable transmission of an output during reversing, by a method wherein a solar gear with a one-way clutch and an integral rotary arm are mounted on an input shaft, an arm with a one-way clutch and a transmission gear are mounted on the support shaft of a planetary gear and the support shaft of an arm with a one-way clutch, and a driven gear geared with the transmission gear is mounted on an input shaft. CONSTITUTION:When a motor 1 reversed, an arm 10 is also integrally rotated along with rotation in a direction B of an input shaft 2. Since a solar gear 6 is not rotated by means of a clutch 9, a support shaft 12 and a transmission gear 16 are revolved along with revolution in a direction B of an arm 10. Since the support shaft 12 is rotated in reverse direction to a direction C based on the arm 10 but the solar gear 6 is not rotated, the planetary gear 14 is rotated in a direction D as it is revolved in a direction B. The transmission gear 16 is rotated as it is revolved, and a driven gear 17 geared with the gear 16 is rotated in a direction B. since the diameter of the transmission gear 16 is differed from that of the planetary gear 14, the gear 16 moves the gear 17 to a point (d). Since a rotation speed ratio of an input shaft to an output shaft is set to 1/10, the speed of the output shaft is reduced to 1/10 of that of the input shaft.

(Function) According to the present invention, when the input shaft rotates in one direction, the planetary gear is revolved by the rotation of the arm, but the spindle does not rotate in the other direction and the sun gear rotates freely, so the planetary gear does not rotate, so rotation of the input shaft in one direction is transmitted like a crank to the output shaft through the arm, support shaft, transmission gear, and driven gear, causing the output shaft to rotate at the same speed as the input shaft.

As the arm 10 pivots in the direction of arrow A, the support shaft 12
The planetary gear 14 and the transmission gear 16 are revolved. However, the support shaft 12 is prevented from rotating in the direction of arrow C with respect to the arm 10 by the one-way clutch 13, and therefore does not rotate.

Therefore, the planetary gear 14 revolves in the six directions of the arrow without rotating, and the sun gear 6 meshing with the planetary gear 14 rotates in the six directions of the arrow in accordance with the revolving speed of the planetary gear 14. In other words, the meshing point a of the sun gear 6 and the planetary gear 14 shown in FIG. 2 moves to one point a. Therefore, the transmission gear 16 also revolves without rotating, and the driven gear 17 meshing with the transmission gear 16 is rotated in the six directions of arrows according to the revolution speed of the transmission gear 16. That is, point a, which is the engagement point between driven gear 17 and transmission gear 16 shown in FIG. 2, moves to point a'.

On the other hand, the motor 1 rotates in the opposite direction (counterclockwise direction -B in Fig. 2).
direction), as the input shaft 2 rotates in the direction of arrow B, the arm 10 is also rotated together in the direction of arrow B. In this case, the sun gear 6 is prevented from rotating in the direction of arrow B by the one-way clutch 9, so it does not rotate.

As the arm 10 pivots in the direction of arrow B, the support shaft 12
The planetary gear 14 and the transmission gear 16 are revolved. In this case, the support shaft 12 is allowed to rotate in the direction opposite to the direction of the arrow C with respect to the arm 10, but since the sun gear 6 does not rotate, the planetary gear 14 rotates in the direction of the arrow B while rotating in the direction of the arrow C. Rotate. Therefore, the transmission gear 16 also rotates while revolving, and the driven gear 17 meshing with the transmission gear 16 is rotated in the direction of arrow B.

That is, point a of the planetary gear 14 moves to point b. In this case, the rotation angle θ of the planetary gear 14 from point a' to point b rotates the transmission gear 16 by the same rotation angle θ, but! ! Since the diameter D3 of the transmission gear 16 is made different from the diameter D2 of the star gear 14, the transmission gear 16 only advances the driven gear 17 to point d.

In other words, the rotational speed N2 of the input shaft 2 and the rotational speed N2 of the output shaft 3
Since the ratio of 3 is given by and is set to 1/1o, the rotation speed of the output shaft 3 is reduced to 1/10 of the rotation speed of the input shaft 2.

この結果、入力軸2の矢印B方向の回転は、出力軸3を
実印B方向の回転に、しかも減速して回転させる。
As a result, the rotation of the input shaft 2 in the direction of arrow B causes the output shaft 3 to rotate in the direction of mark B, and at a reduced speed.
