A device for driving a rotary element, more particularly a rotary kiln, capable of deformation and displacement along its axis and comprising a toothed rim driven by a pinion mounted in a housing articulated on a fulcrum and bearing on two cylindrical tracks coaxial with the rim by way of at least one pair of rollers, characterized in that the housing is connected to a fixed block by a member capable of producing displacement of the fulcrum in a direction parallel to the axis of rotation of the kiln, freely following displacements of the kiln. |
