Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention requires a rotational driving force transmission device, more specifically, a vehicle, a generator, an internal combustion engine, a used paper cutting machine (shredder), various machine tools, and other rotational driving force. In transmitting the rotary drive force from the rotary drive source such as a motor to the machine tool, the rotary drive force is interposed between the machine tool and the rotary drive source or is used by being incorporated in the machine tool. It relates to the device.

[0002]

2. Description of the Related Art Conventionally, in a mechanical device such as a generator that requires a rotational driving force, a transmission device for increasing a rotational torque is provided in addition to a transmission device that merely converts a rotational speed. Instead, it is directly rotated by a drive source such as a motor.

[0003]

As described above, in a conventional device such as a generator that requires a rotary driving force, a direct motor or the like can be used without a transmission device that increases the rotary torque. It is driven, and there has been little consideration for reducing the load on the motor and improving the output efficiency. Therefore, it is an object of the present invention to provide a rotational driving force transmission device capable of reducing the load on the motor and the like, reducing the energy required for input such as power consumption, and improving the output efficiency.

[0004]

According to the present invention, there is provided an input shaft integrally attached with a rotational driving force input means and a first internal gear, and the input shaft is supported between opposing support plates, A first gear fixed cylinder having a central portion of the first rotary arm fixed to one end is attached to the input shaft via a bearing,
Both ends of the rotating arm are inscribed in the first inner gear and circumscribed on a stationary gear fixed to another supporting plate arranged between the supporting plates so as to be concentric with the first rotating arm. The above problem is solved by a rotary driving force transmission device in which a meshing planetary gear is axially mounted and an output means is installed at the other end of the first gear fixing cylinder.

Further, the above problem is the first problem in the above device.
Output means for outputting the rotational driving force to the intermediary portion is installed at the other end of the gear fixing cylinder, and has the same structure as the first internal gear, the first gear fixing cylinder, the rotating arm, the planetary gear, and the stationary gear. And a rotation driving force transmission device which is provided with an output shaft having means for receiving an input from the intermediary portion, and the output shaft is rotatably supported by a support plate different from that described above. it can.

A planetary gear, which meshes inwardly with the inner gear and is externally meshed with a stationary gear fixed at a position concentric with the rotary arm, is axially mounted on another support plate disposed between the support plates, and It is also possible to solve the problem by using a rotary driving force transmission device in which one or a plurality of mechanisms each having an output means are continuously provided and interposed at the other end.

[0007]

[Operation] When the first internal gear is rotationally driven by the rotational driving force input from the input means, the planetary gear that meshes with the first internal gear and meshes with the stationary gear that does not rotate becomes As a result of revolving around its own axis, the rotating arm rotates about the output shaft. It is increased due to the difference between the length (rotation radius) in the couple moment acting on the rotating arm and the length (rotation radius) in the couple moment transmitted with the rotation of the rotating arm. The rotational force (the latter is short in length, so the acting force is large) is applied to the output means for driving the generator and for external output. When the output means is connected to the generator, the motor for driving the input means is driven by the current output from the generator, so that the external output can be efficiently output for a long time.

When the first internal gear 14 rotates, the two planetary gears 20 and 21 inscribed in the first internal gear 14 revolve around the input shaft 9 while revolving with the rotation of the first internal gear 14. To do. That is, since the planetary gears 20 and 21 are internally meshed with the first internal gear 14 and are externally meshed with the stationary gear 19 that is fixed to the support plate 3 and does not rotate, the first internal gear 14
When a rotational driving force (arrow A in FIG. 2) is applied from the above, the stationary gear 19 acts by rotating on its axis. However, since the stationary gear 19 does not rotate, on the contrary, the stationary gear 19
As a result of receiving a reaction from, the first internal gear 14 revolves around the stationary gear 19 while revolving around the stationary gear 19.

The one with 96A, the one with a capacity of 3.5KW (200V) as a generator, and the one with a capacity of 2KW (24V-84) as an exchange.
The device of A) was connected and the utility of this device was tested. Prior to this, when the DC motor was continuously operated using only the battery, the battery was consumed within a few minutes, but when the system was operated (external output was not consumed). Not), continued to work for about an hour. From this, it was confirmed that by interposing this device, a considerably doubled output can be obtained.

The present inventor has also attempted to run the vehicle by mounting the system having the above capacity on a scrap car (light truck) having a displacement of 500 cc and connecting its external output means to a propeller shaft of the car (of course, internal combustion engine).

By the way, the input can be considered as a couple moment having a length from the center of the input shaft 9 to a contact point between the first internal gear 14 and the planetary gears 20 and 21. This couple moment causes the first rotating arm 18 to rotate, and this couple moment is transmitted to the first rotating arm 18 via the planet gears 20 and 21. However, since the length from the center of the input shaft 9 to the center of the gear shafts of the planetary gears 20 and 21 is shorter than the length in the couple moment, the force acting on the first rotary arm 18 is It is larger than the force in the couple moment. That is, the rotation torque increases.
