ABSTRACT:
A drive arrangement for shearing drums. Final gear reduction stages are arranged inside the shearing drum (5) and at least one reduction stage is designed as a planetary gear mechanism. The first gear reduction stage arranged inside the shearing drum (5) has intermediate gear wheels (21) rotatably fixed to a rigid intermediate gear wheel carrier (22) connected to a supporting arm (3) of the shearing drum (5). The intermediate gear wheels (21) are driven by a sun gear wheel (20) and interact with an outer internal gear wheel (25). Internal gear wheel (25) is connected in a rotationally fixed manner to a second sun gear wheel (26) of a downstream planetary gear mechanism, the output side (30) of which is connected to the shearing drum.
