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).
[ What is claimed is:] [1.]1. A transmission for a double screw extruder with two tapering screw-threaded shafts; a drive shaft and two transmission shafts driven by said drive shaft; said transmission shafts having parallel axes; two output shafts; rotationally rigid couplings connecting said transmission shafts to said output shafts; said output shafts sloping toward each other and being rotationally rigidly coupled to said tapering screw-threaded shafts; a common housing for said transmission shafts, said output shafts and said couplings; said couplin...
