Abstract

Ce dispositif comporte au moins deux paires d'arbres parallèles tournant à même vitesse, chacun étant muni d'une masse excentrée et les arbres de chaque paire étant reliés par engrenage d'éléments correspondants. Ce dispositif est caractérisé en ce que ladite liaison cinématique est constituée par un couple d'engrenage 23, 28, chacun étant relié cinématiquement à l'arbre 2, 3 de la paire correspondante d'arbres à la masse excentrée, de manière à tourner avec celui-ci, ces éléments 23 et 28 pouvant se déplacer l'un par rapport à l'autre par roulement l'un sur l'autre de leurs pourtours dentés. Le dispositif est destiné aux transporteurs vibrants, tables de vibration, dans lesquels il permet d'éviter les pertes d'énergie dues à la nécessité d'arrêts et démarrages fréquents.This device comprises at least two pairs of parallel shafts rotating at the same speed, each being provided with an eccentric mass and the shafts of each pair being connected by gear of corresponding elements. This device is characterized in that said kinematic connection is constituted by a pair of gears 23, 28, each being kinematically connected to the shaft 2, 3 of the corresponding pair of shafts to the eccentric mass, so as to rotate with the latter, these elements 23 and 28 being able to move relative to one another by rolling one on the other of their toothed peripheries. The device is intended for vibrating conveyors, vibration tables, in which it makes it possible to avoid energy losses due to the need for frequent stops and starts.
