DISPOSITIF D'ACCOUPLEMENT A LAMELLES FLEXIBLES

L'INVENTION EST RELATIVE A UN DISPOSITIF D'ACCOUPLEMENT MECANIQUE, CONSTITUE PAR UN EMPILAGE DE BRAS 1, 2 DISTINCTS, DISPOSES SELON UNE STRUCTURE POLYGONALE D, MUNIS A CHACUNE DE LEURS DEUX EXTREMITES 4 D'UN TROU D'ASSEMBLAGE 5, ET, ASSEMBLES LES UNS AUX AUTRES PAR DES MOYENS D'ASSEMBLAGE TRAVERSANT LES TROUS ALIGNES DE BRAS SUPERPOSES DE L'EMPILAGE.CERTAINS AU MOINS DES BRAS DE L'EMPILAGE ONT LEUR PARTIE CENTRALE RESPECTIVE 1C, 2C, SITUEE ENTRE LES DEUX PARTIES D'EXTREMITES 4 DU BRAS CORRESPONDANT, DISPOSEE ENTIEREMENT D'UN SEUL COTE DE LA DROITE D JOIGNANT LES AXES 3 DES DEUX TROUS.UNE APPLICATION EST LA REALISATION D'UN ACCOUPLEMENT AYANT UNE RESISTANCE ELEVEE A LA FATIGUE. The flexible coupling consists of a stack of distinct arms or blades (1, 2), arranged in a polygonal structure (D), each of the two ends (4) of each of said arms being provided with a fastening hole, said arms being assembled together by means of fastening means inserted through the aligned holes in the stacked arms. At least some of the arms in the stack have their center portions (1c, 2c), ie. their portions spanning between their two ends (4), lying entirely to one side of the line (D) joining the centers (3) of said two holes such that said center portions do no overlap the center portions of the axially adjacent arms in the stack. The invention provides a coupling having a high resistance to fatigue.
