The invention relates to a drive for a rod-shaped machine element, in particular for the blower tube (1) of a soot blower that is moved axially backwards and forwards and is simultaneously set in rotation. To simplify the drive for a machine element of this type, an elongated, flexible tensile element is provided, preferably a link chain (2) or wire cable, said element being helically guided around the rod-shaped machine element, for example a blower tube (1), with several convolutions (3) and being drivable in both directions.

L'invention concerne un entraînement pour un élément de machine en forme de tige, notamment un tube de soufflage (1) d'un souffleur de suie, qui effectue simultanément un mouvement de va-et-vient axial et de rotation. L'invention vise à simplifier l'entraînement d'un élément de machine de ce type. A cet effet, un élément de traction souple et allongé, de préférence une chaîne à maillons (2) ou un câble métallique, entoure de plusieurs tours (3) en hélice l'élément de machine en forme de tige, par exemple un tube de soufflage (1), cet élément pouvant être entraîné dans les deux sens.
