Abstract
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 such that the forming racks oppose each other and roll power transmission formations in the workpiece during vertical movement in opposite directions.
