Abstract
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) includes 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. The machine (20) also has a second pair of antifriction linear bearings (78) each of which has a stationary guideway (80) and a pair of movable carriages (82) for supporting the associated slides (66). A pair of electric servomotors (94) respectively move the pair of slides (66) through a pair of rotary connectors (96).
