ある。For example, as a transmission device for a conventional twin-screw pressing ratio machine,
There is a device as shown in FIG. 1 disclosed in Japanese Patent No. 1-117154. In the transmission device of this two-screw press ratio machine, among the two screws, for screw 1, the drive shaft 4 of the drive device 3
The rotational force of the drive shaft 4 is transmitted to the screw 2 through gears 5, 6, 7, 8 and 9.

所定以上の回転力を伝動することができなかった。However, in the transmission device of this two-shaft press ratio machine, the meshing part between gear 7 and gear 8 and the meshing part between gear 8 and gear 9 are each a pair of gears, and a predetermined rotational force is generated. When transmitting the torque, a predetermined rotational force was applied directly to the meshing portion of each gear. For this reason, when the distance between the shafts and the tooth width of each gear are specified, it has been impossible to transmit a rotational force exceeding a predetermined value.

を解消することを目的としている。The present invention was made by focusing on the above-mentioned problems in the transmission device of the conventional twin-screw press ratio machine, and it reduces the rotational force to 2! The purpose of the present invention is to solve the above-mentioned problems by dividing the power into two parts and transmitting the power.
以下、本発明をその実施例を示す添付図面の第２及び３
図に基づいて説明する。Hereinafter, the present invention will be described in the second and third accompanying drawings showing the embodiments thereof.
This will be explained based on the diagram.
まず、構成について説明する。First, the configuration will be explained.

諸元の歯車である。The drive i-shaft 14 of the drive device 12 is directly connected to the screw 16. A gear 18 attached to the drive shaft 14 meshes with a gear 22 attached to an axis 2o parallel to the drive shaft 14. A further gear 24 is mounted on the shaft 20, and this gear 24 meshes simultaneously with two gears 26 and 28. Gear 26 is connected to gear 32 via shaft 30, and gear 28 is connected to gear 3 via shaft 34.
6' is connected. The gears 32 and 36 mesh simultaneously with a gear 38, to which a screw 40 is connected. The gears 26 and 28 have the same specifications, and the gears 32 and 36 also have the same specifications.

つの部分に分割される。The rotational force of the drive shaft 14 given by the drive device 12 is transmitted directly to the screw 16 on the one hand, and to the gear 18 on the other hand.
and is transmitted to and reached the shaft 20 via the gear 22. The rotational force of the shaft 20 is transferred from the gear 24 to the two gears 26 that mesh with it.
and 28. The rotational force transmitted to gears 26 and 28 is transmitted to gears 32 and 36 via shafts 30 and 34, respectively. The gear 32 and the gear 36 combine rotational force with the gear 38 that meshes with them, thereby driving the screw 40. During power transmission as described above, the rotational force of the shaft 20 is divided into two parts: one part is transmitted from the gear 24 to the gear 26, and the other part is transmitted from the gear 24 to the gear 28.
divided into two parts.
従って、歯車２４から歯車２６へ伝達される回転力及び
歯車２４から歯車２８へ伝達される回転力は、それぞれ
軸２０の回転力の１／２となる。Therefore, the rotational force transmitted from the gear 24 to the gear 26 and the rotational force transmitted from the gear 24 to the gear 28 are each 1/2 of the rotational force of the shaft 20.
従って、各歯車のかみ合い部の歯の負担も１／２となる

び軸３４は常にほぼ等しい回転力を伝達する。Therefore, the load on the teeth of the meshing portion of each gear is also reduced to 1/2. Similarly, the load acting on the teeth of the meshing portion between the gear 38 and the gear 32 and the meshing portion between the gear 38 and the gear 36 is reduced to 1/2. Therefore, compared to the case where rotational force is transmitted through the meshing portions of a pair of gears, twice the transmission capacity can be obtained by using the same gear. In addition, gear 2
4 and gear 38 mesh with two gears at the same time, there is a possibility that the tooth contact will not be uniform, but this problem can be solved by using a special material and by
This can be solved by appropriately setting the diameter and length of the torsional stiffness and making the torsional rigidity relatively small. That is, for example, of the gears 26 and 28 that mesh with the gear 24, the gear 2
When the tooth contact of gear 6 becomes stronger, the shaft 30 is torsionally deformed to a large extent to relieve the tooth contact on the gear 26 side, and sufficient tooth contact can be obtained on the gear 28 side as well. Therefore, shaft 30 and shaft 34 always transmit substantially equal rotational forces.
