PURPOSE:To obtain the titled device simple in structure and easy in preparation and adjustment, by driving each worm shaft equipped at the root part of each rotor shaft through a periodic transmission means. CONSTITUTION:The rotors 4, 5 rotating in extruder container 1 are supported by the bearings 6, 7 and the bearing in which bearings 4, 5 and worm reduction gears 8, 9 are mounted and the rotary joints 10, 11 penetrate the worm reduction gears 8, 9 and equip the rotary joints 10, 11 at the ends thereof. The timing pulleys 18, 19 are inserted into the worm shafts of the reduction gears 8, 9 and the timing belt 22 is tightened between the timing pulley 21 equipped over the output shaft of the motor 20 and the worm shafts 16, 17 to drive both rotor shafts synchronously. |
