초록

A transmission for an extruder with two tapering helical shafts (1) consists of a driveshaft (6) driven by a transmission shaft and of two take-off shafts (3 & 4) that slope toward each other and can be coupled to the helical shafts. The transmission shaft and the take-off shafts are accommodated in the same housing (5). An angularly adjustable but rotationally rigid coupling is accommodated between the transmission shaft and the take-off shafts (3 & 4).
