A gearbox mechanism is provided for a twin screw extruder having two screw shafts disposed at an angle to one another. The gear mechanism has a multi-stage reduction gearbox, and a distribution gearbox having two output lines connectable to the screw shafts. A first output line comprises a through output shaft. An angularly movable coupling, which is fixed against rotation, is disposed in a second output line placed at the angle of the screw shafts, relative to the first output line, via the coupling. A drive gear of the reduction gearbox is disposed between, and is in engagement with, a gear on the output shaft and a gear on a partial shaft of the second output line. A reduction gearbox and distribution gearbox are disposed, without spatial separation, in a common interior space of a multi-part gearbox housing.
