The invention relates to gearing, especially for a double screw extruder, comprising at least one drive shaft and two output shafts for screws which run in the same direction and in opposite directions, whereby one of the drive shafts can directly merge into an output shaft. The inventive gearing also comprises an output gear (6) which is mounted on the output shaft (5) in a fixed manner and whose gearing simultaneously engages with the gearings of at least two guide gears (3, 4), said guide gears having the same angular pitch and being arranged around the output shaft (5), in such a way that the output shaft (5) can be driven by the guide gears (3, 4). The invention is characterized in that the guide gears (3, 4) are driven by a common input gear (2). At the same time, the guide gears (3, 4) can replace the radial bearing of the output shaft (5). |
