A device (10) for distributing charge material into a shaft furnace comprises a main housing (12), a distribution chute, a suspension rotor (18) and an adjustment rotor (26), which are rotatable about a substantially vertical axis. The chute (32) is suspended to the suspension rotor (18) to rotate therewith for circumferential distribution of charge material and adjustable in orientation through the adjustment rotor (26) for radial distribution of charge material. A differential gear (72) interconnects the suspension rotor (18) and the adjustment rotor (26) and is configured to transmit to the adjustment rotor the same speed of rotation that is imparted to the suspension rotor by a main rotation drive (60) unless an adjustment drive (80) imparts differential rotation to the adjustment rotor. According to the invention, the device includes: - a first gear casing (50) arranged on the main housing (12) and enclosing a gear mechanism (52) that connects the main rotation drive (60) to a first output shaft (54) that protrudes into the main housing (12) where it is connected to a gearwheel (62) that meshes with a first gear ring (64) on the suspension rotor (18); - a second gear casing (70) arranged on the main housing (12) and enclosing the differential gear (72) that connects the adjustment drive (80) to a second output shaft (74) that protrudes into the main housing (12) where it is connected to a gearwheel (82) that meshes with a second gear ring (84) on the adjustment rotor (26); and - a shaft arrangement (90; 190) equipped with a compensating coupling (92, 94, 95; 192) and connecting the differential gear (72) in the second gear casing (70) to the gear mechanism (52) in the first gear casing (50). |
