Drive for twin screw extruder

摘要

The reduction gear (1) is a planetary drive whose sun wheel (21) is driven by a main motor and whose hollow wheel (27) is driven via a superimposition motor. The planetary wheel carrier (25) is connected to the first driven shaft (4) of the distributor gear (2). A principal motor supplying the majority of the power rotates at constant speed while the transition motor produces only a fraction of the output and has a controllable speed.
