Abstract
A gearing with two axis-parallel output shafts (2, 3) rotating in the same direction, for operation of a double screw extruder, has two pinions (4, 7) of equal size which are arranged in the annular space between an internally toothed ring gear (6) and an intermediate gear (5) in the spacing of the screws of the double screw extruder and mesh with the intermediate gear (5) and with the ring gear (6). The first of the two pinions (4) is arranged on the driving shaft (1), which is extended as output shaft (2). The second pinion (7) is arranged on the second output shaft (3). The gearing permits torque division of the torque from the driving shaft (1) to the two output shafts (2, 3).
