A machine (20) for rolling power transmission formations in a workpiece includes a base (20) having a pair of spaced base portions (30), headstock and tailstock spindle supports (48, 52) that cooperate to mount the workpiece for rotation about a rotational axis of the machine and a pair of antifriction linear bearings (58) respectively associated with the pair of spaced base portions. Each bearing (58) inlcudes a stationary carriage (60) and an elongated movable guideway (62). The stationary carriages (60) are respectively mounted on the pair of spaced base portions (30) with the rotational axis (A) of the machine (20) therebetween, and each stationary carriage (60) includes rolling elements that support the associated movable guideway (62) for movement along its length on the adjacent side of the supported workpiece. A pair of movable slides (66) respectively support a pair of forming racks (68) and are respectively supported by the elongated movable guideways (62) of the pair of antifriction linear bearings (58) to move the forming racks to roll power transmission formations in the workpiece.
Cette machine (20), destinée à profiler des ensembles de transmission d'énergie dans une pièce à travailler, comporte une base (20) ayant deux éléments de base distincts (30), des supports de broche de poupée fixe et de poupée mobile (48, 52) coopérant pour monter la pièce à travailler rotative autour d'un axe de rotation de la machine et deux roulements anti-frottement linéaires (58) associés, respectivement, aux deux éléments de base distincts. Chaque roulement (58) comprend un chariot fixe (60) et une voie de guidage allongée mobile (62). Les chariots fixes (60) sont montés, respectivement, sur les éléments de base (30), l'axe de rotation de la machine (A) se trouvant entre eux. Chaque chariot fixe (60) comprend des éléments de profilage qui soutiennent la voie de guidage associée (62) aux fins d'un déplacement longitudinal du coté adjacent de la pièce à travailler maintenue. Deux glissières mobiles (66) soutiennent, respectivement, deux peignes de formage (68) et sont, respectivement, soutenues par les voies de guidage (62) des deux roulements anti-frottement linéaires (58) aux fins du déplacement des peignes de formage destinés au profilage d'un ensemble de transmission d'énergie dans la pièce à travailler.
