摘要： An extruder driving apparatus is provided in which a speed change gear mechanism is disposed in a position allowing the speed change gear mechanism to rotate at a much lower rotational speed, whereby a noise level is reduced and a seizing trouble is more surely avoided. The extruder driving apparatus comprises a main motor; a planetary gear mechanism including a torque input portion driven by the main motor and outputting a driving force after reducing a rotational speed of the main motor; an output distributing gear mechanism for distributing a driving force from an output portion of the planetary gear mechanism to a plurality of rotor drive shafts arranged parallel to each other; coupling units for connecting one ends of the rotor drive shafts to a plurality of rotors disposed on the extruder side; and thrust bearings for supporting the other ends of the rotor drive shafts to bear thrust forces imposed from the rotors. A speed change gear mechanism for adjusting a rotational speed of each rotor drive shaft through replacement of one pair of gears by another pair having a different gear ratio is provided between the planetary gear mechanism and the output distributing gear mechanism.
