Description

Dispositif de transmission du couple pour rouleau moteur et procédé de montage La présente invention est du domaine des rouleaux moteurs composés d'un tube entraîné en rotation autour de deux axes fixes situés à chacune des extrémités dudit rouleau. Une motorisation électrique est intégrée dans la cavité interne du tube. La partie fixe du moteur est généralement liée à l'un des axes fixes et l'arbre de sortie du moteur transmet le couple sur la paroi interne du tube.  Torque transmission device for drive roller and mounting method The present invention is in the field of drive rollers composed of a tube driven in rotation about two fixed axes located at each end of said roller. An electric motor is integrated in the internal cavity of the tube. The fixed part of the motor is generally linked to one of the fixed axes and the motor output shaft transmits the torque on the internal wall of the tube.

Le type de rouleau moteur selon l'invention est particulièrement destiné à une application d'enroulement et déroulement d'affiches pour des panneaux publicitaires mais l'invention s'applique également aux rouleaux moteurs utilisés pour les convoyeurs à bande notamment.  The type of drive roller according to the invention is particularly intended for the application of winding and unwinding of posters for advertising signs, but the invention also applies to the drive rollers used in particular for conveyor belts.

L'invention concerne plus particulièrement le dispositif de transmission du couple de l'arbre moteur vers le tube. The invention relates more particularly to the device for transmitting the torque from the drive shaft to the tube.

Dans un certain nombre de rouleaux moteurs existants, la transmission du couple est effectuée par un disque métallique situé sur l'arbre moteur et fixé par des vis traversant le tube perpendiculairement à l'axe moteur et venant se reprendre sur ledit disque. Ce type d'assemblage pose de nombreux problèmes. In a certain number of existing motor rollers, the transmission of the torque is effected by a metal disk located on the motor shaft and fixed by screws passing through the tube perpendicular to the motor axis and coming to resume on said disk. This type of assembly poses many problems.

Dans le cas d'une fabrication en série, la dimension du diamètre intérieur du tube varie de quelques dixièmes de millimètres, l'emboîtement du disque dans le tube ne sera pas parfait et la concentricité du tube et de l'axe moteur ne pourra donc pas être assurée. D'autre part ce type d'assemblage nécessite une opération de perçage du tube pour le passage de vis. Enfin, le contact métallique de l'axe moteur avec le tube permet une propagation des vibrations du moteur dans le rouleau ce qui constitue une source de bruit. In the case of mass production, the dimension of the internal diameter of the tube varies by a few tenths of a millimeter, the fitting of the disc into the tube will not be perfect and the concentricity of the tube and the motor axis will therefore not be insured. On the other hand this type of assembly requires a drilling operation of the tube for the passage of screws. Finally, the metallic contact of the motor axis with the tube allows propagation of the vibrations of the motor in the roller which constitutes a source of noise.

La présente invention propose un nouveau dispositif de transmission du couple pour rouleau moteur ne nécessitant aucun usinage du tube et permettant de limiter la transmission de vibrations depuis l'arbre moteur vers le tube. The present invention provides a new torque transmission device for a drive roller requiring no machining of the tube and making it possible to limit the transmission of vibrations from the motor shaft to the tube.
