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.

摘要： A screw expander system has a condenser positioned for receiving a mixture of oil and operating medium from a screw expander. A pump pressure-feeds the mixture from the condenser to an evaporator where the operating medium is evaporated. An oil separating tank separates the mixture from the evaporator into the gaseous operating medium and the oil, and the operating medium is returned to the screw expander via a throttle mechanism. The oil can thereby be supplied to the screw expander without providing a separate oil pump, as a result of which the screw expander system is compact.
