ABSTRACT:
A transmission for a high-output two-shaft extruder, comprising a speed-reduction gear (1) and a distribution gear (2). The distribution gear has one take-off shaft (4) driven directly by the speed-reduction gear and another take-off shaft (5) driven by the first take-off shaft in conjunction with two distributor shafts (11 & 12), one on each side. The speed-reduction gear is a planetary gear, its sun wheel (21) driven by a main motor and its ring (27) by a superimposition motor, and its planetary bearing (25) coupled to the distribution gear's first take-off shaft. The main motor operates at a constant speed and is designed to handle most of the total power demand. The superimposition motor is regulable or discontinuously variable in speed and is designed to handle a fraction of the total power demand.
