Cone type twin screw extruder.

摘要

In a cone type twin screw extruder, two rotor shafts (1) are disposed in such a manner as to be made smaller in the center distance as nearing the leading edge and to be rotatable, and an interlocking device (2) is provided on the side of the base portions of the rotor shafts for interlockingly connecting the rotor shafts with each other. The interlocking device has a pair of reduction gear devices (3) disposed on the base portion sides of the rotor shafts, and the reduction gear is constituted of a spur gear train or a planetary gear. High speed shafts (5) of the reduction gears are interlockingly connected with bevel gear devices (15), and one shaft (23) of the bevel gear device is taken as a connecting shaft projecting from the other bevel gear device side. Further, a pair of the connecting shafts are interlockingly connected with each other by a coupling device (26).
