PURPOSE:To favorably balance the device by a method wherein circular driving gears of the same pitch rotated by a driver in the same direction are spaced at an interval, and follower gears engaging with the driving gears are provided for transmitting a power to two rams of an extruder. CONSTITUTION:The power of an output shaft 7 of a driver 5 is transmitted to a gear ring 9 through a pinion 8 and an outer gear 10. The rotation of the gear ring 9 causes two driving gears 12A, 12B to rotate in the same direction through an inner gear 11. Two follower gears 15A, 15B are engaged with the two driving gears 12A, 12B. Therefore, the power from the gear ring 9 branches off in two systems through the driving gears 12A, 12B. The branching powers are respectively transmitted to the follower gears 15A, 15B, furthermore being transmitted to two rams 6A, 6B of twin-ram extruder 2 through first and second output shafts 16A, 16B. |
