Twin screw extruder and torque splitting transmission
In accordance with the invention, a twin screw extruder and a torque splitting transmission
are provided wherein the torque splitting transmission has two output shaft portions that are axially spaced apart a distance substantially equal to the distance between the axes of twin screws. At least one of the output shafts is bent along its length and powered by a driven pinion gear having a diameter that is greater than the distance between the axes of the twin screws. The larger size pinion gear substantially enhances the output torque capability of the transmission and consequently, the torque capacity of the transmission approaches or equals the torque carrying capacity of the twin screws. Improved output torque capacity results in an extruder with substantially improved throughput capability.
