The invention relates to a device for driving a cylinder in rotation about its longitudinal axis, and includes a ring gear perpendicular to the cylinder axis; truncated rollers arranged on each side of the ring gear, at least one of which is a drive roller; and at least one actuator acting on at least one roller for pressing it on the ring gear. The actuator supports and the roller supports are linked to a common structure capable of moving to respond to the movements and possible direction changes during its operation. The invention is specifically applicable for a rotary furnace for firing minerals. |
