According to the present invention, a freely rotating input shaft integrated with an input means and a stationary shaft which is fixed and does not rotate are arranged at an inner end of the input shaft. The first drive gear is attached, and the first drive gear is meshed with the input inner gear of a three-stage gear in which the input inner gear, the intermediate gear, and the second drive gear are integrated, and the inner end of the stationary shaft is rotated. An arm is rotatably mounted, and a third-stage gear shaft of the third-stage gear and a second-stage gear shaft of the second-stage gear are pivotally supported at both ends of the arm. A rotational driving force transmitting device, wherein a driven gear that meshes with a driving gear is attached, and a third driving gear is attached to the other end, and the rotational driving force is transmitted from the third driving gear to output means. Was solved.

Usually, the input shaft and the stationary shaft are arranged on the same axis, and a bearing holder provided with an output internal gear and an output means is axially supported on the stationary shaft. The gear is engaged with the output gear. All or some of the above gears may be helical gears. In that case, mechanical noise can be reduced.

[0006]

Embodiments of the present invention will be described with reference to the accompanying drawings. In the figure, reference numeral 1 denotes a base, on one end of which a pair of shaft support plates 2, 3 are erected at appropriate intervals, and at the other end, a pair of shaft fixing plates 11, 12 are appropriately spaced. It is erected. The input shaft 4 is passed between the shaft support plates 2 and 3, and is supported by the shaft support plates 2 and 3 via bearings 5 and 6. Reference numeral 7 denotes input means directly connected to a driving device such as a motor, which is fixed to the input shaft 4. As the input means 7, a sprocket, pulley, gear, or the like can be used. A flywheel 8 is installed at the outer end of the input shaft 4 as necessary. Further, a first drive gear 9 having a smaller diameter than the input means 7 is fixed to the inner end thereof.

A stationary shaft 13 is attached and fixed to the shaft fixing plates 11 and 12 so as to protrude inward. Stationary shaft 13
Are arranged such that the input shaft 4 and the axis coincide with each other. A rotating arm 15 is attached to the protruding inner end of the stationary shaft 13 via a bearing 14. The rotating arm 15 pivotally supports a three-stage gear shaft 16 at one end and a two-stage gear shaft 17 at the other end. In the rotating arm 15 shown in FIG. 2, the three shaft support holes are arranged in a straight line, but the invention is not limited to this.

The three-stage gear shaft 16 protrudes only toward the input means 7, and a three-stage gear including an input inner gear 18, an intermediate gear 19 and a second drive gear 20 is fixed to the input means 7 in this order. The input internal gear 18 is installed on the three-stage gear shaft 16 via an internal gear fixing plate 21 that supports the input internal gear 18. The first drive gear 9 meshes internally with the input internal gear 18. The two-stage gear shaft 17 protrudes on both sides of the rotating arm 15, and a driven gear 22 meshed with the second drive gear 20 at an end on the input means 7 side.
Is fixed, and a third drive gear 23 internally fixed to the output internal gear 24 is fixed to the opposite end.

The intermediate gear 19 meshes with a stationary internal gear 25 installed on the shaft fixing plate 12 via a support frame 26. The internal gear fixing plate 27 supporting the output internal gear 24 is fixed to a bearing holder 28 provided on the stationary shaft 13.
A sprocket, pulley,
Output means 29 such as gears having a smaller diameter than inner gear fixed plate 27
Is fixed.

In the above configuration, when a rotational driving force of a motor or the like is input to the input means 7, the first drive gear 9 integrated with the input means 7 via the input shaft 4 is connected to the input means 7 The input internal gear 18 which rotates as a unit and meshes therewith
Is driven to rotate. At this time, since the diameter of the input means 7 is larger than the diameter of the first drive gear 9, a force greater than the input to the input means 7 is generated by the first principle due to the principle of work on the wheel set.
The transmission is transmitted from the drive gear 9 to the input internal gear 18, whereby the input internal gear 18 attempts to rotate around the three-stage gear shaft 16.

The operation of the internal input gear 18 is the operation of the entire three-stage gear including the intermediate gear 19 and the second drive gear 20. However, the intermediate gear 19 of the three-stage gear
Is fixed to a support frame 26 extending from the shaft fixing plate 12 and meshes with a stationary internal gear 25 which does not rotate. The intermediate gear 19 acts to rotationally drive the stationary internal gear 25 with the rotation of the input internal gear 18. However, since the stationary internal gear 25 is in a fixed state, the intermediate gear 19 rotates it. Can not do.

The operation of the intermediate gear 19 is integral with the second drive gear 20, and the second drive gear 20 meshes with the driven gear 22, so that the rotation of the intermediate gear 19 causes the stationary internal gear to rotate. Lever motion with the contact point with the second gear 25 as a fulcrum occurs, and the point of contact of the driven gear 22 with the second drive gear 20 integrated with the intermediate gear 19 becomes an action point, and is thus doubled to the second drive gear 20. The transmitted rotational driving force is transmitted. With the transmission of the rotational driving force, the entire three-stage gear including the intermediate gear 19 revolves around the stationary shaft 13 along the stationary inner gear 25 in a direction opposite to the rotation direction thereof.

By the revolving operation of the three-stage gear, the rotating gear is rotated.
The gear 15 rotates about the stationary shaft 13 in the same direction as the revolution direction of the three-stage gear. The doubled rotational driving force transmitted to the driven gear 22 is transmitted to the third driving gear 23 via the two-stage gear shaft 17 as it is. The two-stage gear shaft 17 to which the driven gear 22 and the third drive gear 23 are fixed is supported by the rotating arm 15 in the same direction as the third-stage gear shaft 16. As a result of the rotation, the driven gear 22 and the third drive gear 23 revolve around the stationary shaft 13 while rotating.

The operation of the third drive gear 23 is transmitted to the internal output gear 24 meshing with the third drive gear 23. That is, the inner output gear 24 is rotationally driven by the third drive gear 23 in the same direction as the third drive gear 23. The internal gear fixing plate 27 of the output internal gear 24 is a bearing holder-2 supported by the stationary shaft 13.
8, the movement of the output internal gear 24 is output from the output means 29 fixed to the bearing holder 28 as it is.

The direction of rotation of the output means 29 can be changed by interposing a rotation changing gear 22a between the second drive gear 20 and the driven gear 22. For this purpose, for example, the rotating arm 15 is formed into a Y-shape, and a rotation changing gear 22a is attached to one end of the rotating arm 15 via an auxiliary shaft 17a, and this is meshed with the second driving gear 20 and the driven gear 22, and the second driving gear 2
The rotation of 0 may be transmitted to the driven gear 22 via the rotation changing gear 22a (see FIG. 4).

Internal gear fixed plate 2 to which output internal gear 24 is fixed
7 and the smaller output means 29 are the same bearing holder-2.
8, a power greater than the rotational driving force for the internal output gear 24 is output due to the principle of work on the wheel set, and an efficient rotation with little mechanical loss is obtained as a whole. Force transmission is performed.

In order to confirm the effectiveness of the apparatus according to the present invention, an experiment as shown in FIG. 5 was conducted. That is, the motor 31
Is directly connected to the generator 32, and 15 light bulbs 33 are connected to the generator 32.
In the same manner as the light bulb 33 (FIG. 5A).
Is connected between the generator 32 and the motor 31 to which the
4 with the motor 31 directly connected to the input means 7 and the output means 29 directly connected to the generator 32 (FIG. 5 (B)). The power consumption (kW) and the input current (A) when the number of the loads (loads) 33 are changed are measured by the wattmeter 35 and the ammeter 36,
I saw that change.

Table 1 (when this device 34 is not used) and Table 2
(When the present apparatus 34 is used) shows the result. The experiment was conducted on a three-phase AC motor with a rated output of 3.7 kW.
A three-phase AC generator with a rated output of 3.5 kW (3000 revolutions / minute) was driven by a motor (3000 revolutions / minute), and a 200 W bulb was used as a load.
