A machine (20) for rolling power transmission formations in a workpiece includes a base (20) having a lower end (24) for providing support thereof in an upwardly standing orientation. The base (22) includes a pair of spaced base portions (30) and a rear connecting base portion (32). The spaced base portions (30) project forwardly from the rear connecting base portion (32) to define a vertically extending workspace (34) and are secured to each other and to the rear connecting base portion by tie rod assemblies (38, 40, 42). Headstock and tailstock spindle supports (48, 52) cooperate to rotatably mount the workpiece about a rotational axis (A) of the machine. A pair of vertically movable slides (66) respectively mount a pair of forming racks (68) and are respectively mounted by the spaced base portions (30) on opposite sides of the rotational axis (A) about which the workpiece is rotatably supported.

Cette machine (20), destinée au profilage d'ensembles de transmission d'énergie dans une pièce à travailler, comporte une base (22), l'extrémité inférieure (24) de celle-ci la soutenant tout en l'orientant à la verticale. La base (22) comporte deux éléments de base distincts (30) et un élément de base de connexion arrière (32). Les éléments de base (30), qui font saillie vers l'avant depuis l'élément de base de connexion arrière (32) pour délimiter un espace de travail (34) s'étendant verticalement, sont assujettis l'un à l'autre et à l'élément de base de connexion arrière par des assemblages de barres d'accouplement (38, 40, 42). Des supports de broche de poupée fixe et de poupée mobile (48, 52) coopèrent aux fins du montage rotatif de la pièce de travail autour d'un axe de rotation (A) de la machine. Deux glissières mobiles (66) soutiennent, respectivement, deux peignes de formage (68) et sont, respectivement, montées par les éléments de base distincts (30) sur les cotés opposé de l'axe de rotation (A) autour de laquelle la pièce de travail est montée rotative.
