A description is given of a rotary drum (1), as for example a rotary kiln, which is suspended within a live-ring (3) by means of axially extending brackets (7) which are retained by the live-ring (3) and bearing, at their free ends, against retaining elements (5) fixed to the rotary drum, in such a way that the vertical load of the drum (1) relative to the drum shell (1) is transmitted tangentially to the live-ring (3). The brackets (7) are evenly distributed over the circumference of the live-ring (3) fixed to its side faces (3a, 3b). Hereby, the live-ring can be made with a smooth cylindrical inner face without teeth, which, besides being advantageous from an economic perspective, also makes it possible to use existing live-rings of the migrating type. Further, all parts of the device will be more readily accessible in connection with inspection and maintenance work in that none of the parts are concealed under the live-ring.
Tambour rotatif (1), p. ex. pour four rotatif, porté par un palier commandé (3) par l'intermédiaire de brides s'étendant axialement (7) enchâssées dans le palier (3) et portant par leurs extrémités libres sur des éléments de retenue (5) solidaires du tambour, de façon à ce que la charge verticale du tambour (1) due au poids de son enveloppe se transmette tangentiellement au palier commandé (3), les brides étant réparties uniformément le long de sa circonférence et fixées à ses faces latérales (3a, 3b). Le palier commandé peut présenter une surface cylindrique intérieure lisse et sans dents, non seulement intéressante du point de vue économique mais rendant possible l'utilisation de paliers commandés existants du type migratoire. Par ailleurs, toutes les pièces du dispositif sont d'un accès plus facile pour les vérifications ou l'entretien, aucune n'étant dissimulée sous le palier
