The invention concerns support device (1) for a cylindrical drum (2) such as, for instance, an oven, drier, cooler or the like, designed for thermal and/or chemical treatment of materials, comprising at least a track roller (3), co-operating with said drum (2), and at least two bearings (5, 5') for enabling said roller (3) to rotate about its rotation axis (4). The invention is characterised in that the device further comprises: a frame (7), whereto said bearings (5, 5') are secured, mounted articulated about a pivoting axis (11) substantially perpendicular to the plane passing through said roller (3) rotation axis (4) and perpendicular to the block (6) on which said device (1) is placed, called articulating plane; linking means, flexible along a predetermined direction (9, 9'), called flexibility direction, and rigid in the directions orthogonal to said flexibility direction (9, 9'), to maintain said bearings (5, 5') on said block (6) while allowing the frame (7) to move freely in articulation, such that the roller (3) is aligned with the drum (2) when the latter is pivoting.
La présente invention concerne un dispositif support (1) pour tambour rotatif (2) tel que, par exemple, four, sécheur, refroidisseur ou autres, destiné, notamment, aux traitements thermiques et/ou chimiques de matières, comprenant au moins un galet de roulement (3), apte à coopérer avec ledit tambour (2), et au moins deux paliers (5, 5'), aptes à permettre la rotation dudit galet (3) autour de son axe de rotation (4). Selon l'invention, ledit dispositif comprend, en outre: un châssis (7), auquel lesdits paliers (5, 5') sont assujettis, monté articulé autour d'un axe de pivotement (11) sensiblement perpendiculaire au plan passant par l'axe de rotation (4) dudit galet (3) et normal au massif (6) sur lequel ledit dispositif (1) est placé, appelé plan d'articulation; des moyens de liaison, flexibles selon une direction donnée (9, 9'), dite direction de flexibilité, et rigides dans les directions orthogonales à ladite direction de flexibilité (9, 9'), pour maintenir lesdits paliers (5, 5') sur ledit massif (6) tout en laissant libre le mouvement d'articulation dudit châssis (7), de manière à permettre l'alignement dudit galet (3) sur le tambour (2) en cas de pivotement de ce dernier.
