Abstract: A heavy duty drive arrangement (1, 1?) having a first spur gear including a first gear wheel (4; 4?, 4?) meshing with a pinion (3) of a motor (2) and a second spur gear comprising a gear wheel (8; 8?, 8?). A drive pinion (9; 9?, 9?) configured to mesh with a ring gear (10) of the working equipment is coupled to the gear wheel (8; 8?, 8?) of the second spur gear and has an axis of rotation (E) which is essentially parallel to the rotor axis (A). The first spur gear and the second spur gear are coupled by means of a dynamic coupling (5; 5?, 5?), preferably an elastic or a hydrodynamic coupling. A mill (20) may include the heavy duty drive arrangement (1, 1?).

Abstract: The present application relates to a heavy duty drive arrangement (1, 1?) having a first spur gear comprising a first gear wheel (4; 4?, 4?) meshing with a pinion (3) of a motor (2) and a second spur gear comprising a gear wheel (8; 8?, 8?) coupled to the first spur gear. At least one drive pinion (9; 9?, 9?) configured to mesh with a ring gear (10) of the working equipment meshes with the gear wheel (8; 8?, 8?) of the second spur gear and having an axis of rotation (E) which is essentially parallel to the rotor axis (A). The first spur gear and the second spur gear are coupled by means of a dynamic coupling (5; 5?, 5?), preferably an elastic or a hydrodynamic coupling. Further, the present application also relates to a mill (20) comprising at least one heavy duty drive arrangement (1, 1?).
