PURPOSE:To transmit driving force of high torque with the small-diameter and small-capacity bearings of the first and second output shafts by arranging the first and second output gears in a line, each of which is put between gears, for complete cancellation of radical force from an engagement part with the transmission gear of the output gear. CONSTITUTION:In this driving transmission device for two-shaft extruder 20, the first output gear 31 is put between the fourth transmission gear 24 and the sixth transmission gear 26 so as to be arranged in a line, and the second output gear 32 is put between the fifth transmission gear 25 and the seventh transmission gear 27 so as to be arranged in a line. They are adjusted so that even driving force may be transmitted to the fourth transmission gear 24, the sixth transmission gear 26, the fifth transmission gear 25 and the seventh transmission gear 27. Therefore, radical force is canceled completely from an engagement part of the sixth transmission gear 26 with the fourth transmission gear 24, and an engagement part of the seventh transmission gear 27 with the fifth transmission gear 25, so small-diameter and small-capacity bearings may be used as the bearings of the first and second output shafts connected with the first and second screws 35, 36. |
