Embodiment Construction

[0036] according to figure 1 with figure 2 , the processing section 1 of the extruder has a shell 2a with a core 2b, and 12 axially parallel shafts 3 are arranged at intervals along the circumference at equal central angles ( figure 2 ), and is equipped with processing parts 4, and the processing parts 4 of adjacent shafts 3 are engaged with each other.

[0037] The processing section 1 is closed at the upstream delivery end by an end plate 5 . Shaft 3 extends through end plate 5 and is image 3 and 4 with Figure 6-9 Torque-splitting gearing 7 is shown driven in co-rotation or counter-rotation.

[0038] according to image 3 The gear unit 7 shown has a cover plate 9 which is connected to the end plate 5 of the processing section 1 . Extending from said cover plate 9 are 12 output shafts 11 , which are non-rotatably coaxially connected to the 12 shafts 3 of the processing section 1 . The output shaft 11 is non-rotatably connected to output transmission gears 12 , 13 . ...

Abstract

The aim of the invention is to drive an extruder (1) comprising several shafts (3) that are arranged along a circle, provided with treatment elements (4), said shafts (3) being connected to the drive shafts (11) of a gear box (7), provided with output pinions (12, 13). Said output pinions (12, 13) are axially offset such that adjacent drive shafts (11) have a different length (L1, L2) between the ends facing the extruder (1) and the output pinions (12, 13). The axially offset output pinions (12, 13) respectively engage with a sun gear (18, 19). One sun gear (19) is connected to a torsion hollow shaft (21) and the other sun gear (18) is connected to a torsion inner shaft (22) that is arranged therein. Said torsion hollow shaft (21) and the torsion inner shaft (22) are designed such that the difference of the torsion rotational angle caused by the various lengths (L1, L2) of the drive shafts (11) is compensated by a different torsion of the torsion hollow shaft (21) and the torsion inner shaft (22).

Description

technical field [0001] The invention relates to a gear arrangement for driving an extruder according to the preamble of claim 1 . Background technique [0002] The use of twin-screw extruders with tightly intermeshing shafts for processing substances has essential advantages in terms of economics and process engineering. An important aspect used to evaluate the performance of this type of machine is the torque density, which is the quotient of the torque per axle and the cube of the center distance. Its performance is further determined by the speed. [0003] For processing engineering, it is more important how to realize the transition of the product to the subsequent screw shaft, which depends on whether the screw shaft is rotated in the same direction or counter-rotated, which is the wedge between the processing parts of two adjacent shafts ) produce very different spreading forces (spreading forces), which in turn can decisively affect the performance, especially the w...
