Dans tous les cas, les poulies modulaires 1 sont disposées parallèlement, séparées par des entretoises annulaires 6 et bloquées en paquet entre un flasque de tête In all cases, the modular pulleys 1 are arranged in parallel, separated by annular spacers 6 and locked in a package between a head flange
8 et un flasque opposé 7, comme il sera précisé ci-après. 8 and an opposite flange 7, as will be explained below.
Les entretoises annulaires 6, placées entre The annular spacers 6, placed between

Le flasque 7 présente une série d'orifices 17, espacés angulairement et coïncidant axialement avec les orifices 12 pratiqués dans le corps à disque 2 de chaque poulie modulaire 1, tandis que l'élément externe 10 du flasque 8 présente des orifices filetés 20 co-axiaux auxdits orifices 17 et 12. Dans les orifices 17 et 12 du flasque 7 et des poulies i1 sont logés des boulons de blocage 13 dont la tête 14 appuie contre le flasque 7, alors que la tige filetée correspondante est vissée dans les orifices filetés 20 de The flange 7 has a series of orifices 17, angularly spaced and coinciding axially with the orifices 12 formed in the disc body 2 of each modular pulley 1, while the external element 10 of the flange 8 has threaded orifices 20 co- axial to said orifices 17 and 12. In the orifices 17 and 12 of the flange 7 and of the pulleys i1 are housed locking bolts 13 whose head 14 presses against the flange 7, while the corresponding threaded rod is screwed into the threaded orifices 20 of
l'élément extérieur 10 du flasque de tête 8. the external element 10 of the head flange 8.
Grâce à ce système, les poulies t se trouvent bloquées en paquet entre et par- les entretoises 6 et les flasques 7 et 8, de façon à former-un ensemble solidaire en forme de poulie composée dans laquelle les entretoises et les flasques constituent le moyeu pour le montage de la poulie sur l'arbre de transmission 11V, comme le montre Thanks to this system, the pulleys t are blocked in a package between and by the spacers 6 and the flanges 7 and 8, so as to form an integral assembly in the form of a compound pulley in which the spacers and the flanges constitute the hub. for mounting the pulley on the 11V drive shaft, as shown
