Abstract

La présente invention concerne un dispositif de fixation de lames à des flasques solidaires en rotation d’un arbre rotatif et une machine agricole équipée d’un tel dispositif. Le dispositif est carctérisé en ce que chaque flasque (4) comprend une découpe réalisée dans l’un des flancs du flasque (4) et conformée pour recevoir par emboîtement et retenir radialement une partie plane complémentaire formant pied de support (L2) d’une lame (L) et en ce que les flasques (4) sont serrés axialement et jointivement les uns contre les autres pour bloquer les lames (L) à leurs flasques respectifs (4). L’invention trouve application pour des machines agricoles.
