  • Patent number: 6360626
    Abstract: A transmission arrangement for twin-screw extruders in which at least one reduction stage that includes a drive shaft, adapts speeds and torques to various applications. The output of the transmission is divided by a bifurcating stage which is connected to two output shafts. At least a part of the output is transmitted to an intermediate shaft located downstream of the bifurcating stage. First opposing gear wheels with herringbone teeth are mounted on the intermediate shaft and engage second gear wheels on the intermediate shaft for relieving axial forces. One of the output shafts is mounted on sliding bearings and is driven directly by the bifurcating stage.
