Abstract
A machine (20) for rolling power transmission formations in a workpiece includes a base (22) having spaced base portions (30) and a rear connecting base portion (32) extending between the spaced base portions which project forwardly therefrom to define a workspace (34). A headstock spindle support (48) is mounted on the rear connecting base portion (32) along a rotational axis A of the machine and is moved therealong by a headstock electric servomotor (152). A tailstock spindle support (52) is mounted on the spaced base portions (30) adjacent front ends (36) thereof to cooperate with the headstock spindle support (48) in rotatably mounting the workpiece and is also movable along the rotational axis by a tailstock electric servomotor (180). A pair of movable slides (66) respectively support a pair of forming racks (68) and are respectively supported by the pair of spaced base portions (30) within the workspace (34). A pair of slide electric servomotors (94) move the pair of slides (66) in opposite directions such that the forming racks (68) thereon provide the rolling of the power transmission formations in the workpiece.
