Abstract

L'invention concerne un dispositif de montage (34) pour un système (2) de balais pouvant être monté radialement par rapport à un arbre (4) du moteur d'un entraînement (1) électromoteur. L'invention concerne en particulier un dispositif de montage (34) pour un système (2) de balais qui présente une pluralité de balais (16) sollicités de manière élastique et qui, à l'état initial, sont situés totalement dans leurs logements (15) pour balai. Le dispositif de montage (34) peut être installé dans ou sur le système (2) de balais et présente au moins un élément de retenue (31) qui retient un balai (16) dans son logement (15) pour balai à l'état initial. L'objectif de l'invention est de simplifier la fabrication desdits entraînements (1). A cet effet, le dispositif de montage, selon l'invention, (34) présente au moins un élément de butée (32) relié à l'élément de retenue (31) qui, lors du passage du système (2) de balais de l'état initial à l'état final de montage, vient buter contre une partie (6) du moteur électrique, de sorte que, si le passage à l'état final de montage est poursuivi au-delà de la butée, l'élément de retenue (31) subit une modification de position telle, que le balai (16) est libéré et sort automatiquement, au moins en partie, de son logement (15) de balai et se déplace dans sa position finale de montage.
