A screw conveyor is provided with a drive in which cogged wheels are supported such that they are radially movable in relation to each other, parallel to a straight line perpendicular to a pressure line of tooth contact of the cogged wheels and parallel to surfaces of contact. The screw conveyor includes a frame adapted to turn around a vertical turning axis and a conveyor screw adapted to turn with the frame. A second one of the cogged wheels is supported such that it is movable vertically.
