Problems solved by technology

The disadvantage of this drive is that the ever-increasing speed of the screw shaft required for industrial purposes leads to high radial acceleration forces acting on the planetary gear and thus to an increased load on the bearings
This increased load has a negative impact on the life of the drive, requiring a special bearing design which in turn leads to a more complex drive design

Abstract

The device (4) has an overriding drive (6) for superimposing drive power of drive motors, and overriding drive-input shafts (8, 10) rotatable by the motors. A power splitting transmission (7) is provided for branching drive power transferred to an overriding drive-output shaft (29). The transmission has two power splitting transmission-output shafts (42, 43) coupled with worm shafts (52, 53) of a twin screw extruder, where the drive is designed as a differential-overriding drive. A beveled wheel (28) is supported at a differential casing (15) of the drive in a rotatable manner. An independent claim is also included for a twin screw extruder arrangement comprising a drive device.

Description

technical field [0001] The invention relates to a drive for a twin-screw extruder capable of being driven in rotation in the same direction, the drive comprising: a superposition transmission for superimposing the drive power of two different drive motors and for A power distribution transmission for distributing drive power which has been superimposed on said superposition transmission output shaft, said superposition transmission comprising: two superposition transmission input shafts and a superposition transmission output shaft, the two superposition transmissions The input shaft can be driven in rotation by said two different drive motors; the power distribution transmission includes two power distribution transmission output shafts, which can be connected to the two screw shaft. Background technique [0002] DE19736549C2 discloses a drive for a twin-screw extruder which can transmit a power of more than 15000 kW and which can be adapted to the speed of the screw shaft...
