A forming machine (10) disclosed has an improved drive mechanism (28) for driving a pair of slides (20,22) mounted on upper and lower bases (12, 14) so as to provide forming of a workpiece for forming racks (24, 26) mounted on the slides. Upper and lower hydraulic motors (30,32) respectively drive the pair of slides whose movement is coordinated by a rotatable synchronizing gear (48) and upper and lower synchronizing racks (50,52). The synchronizing gear (48) is mounted by a connecting portion of the machine between the slides and is meshed with the synchronizing racks (50, 52) which are mounted on the slides by wedge adjusters (53) to adjust backlash of the synchronizing racks with the synchronizing gear. Both rotary and linear hydraulic motors for drivng the slides are disclosed. A pair of tie rod connections (150) preferably extend between the upper and lower bases to control deflection therebetween during the workpiece forming. Each tie rod connection (150) includes a sleeve (152) that is compressed and a tie rod (162 ) that extends through the sleeve and is tensioned in a preloaded manner to provide the prevention of deflection between the bases.

Forming machine including drive mechanism having rack and gear

A loader (10) for a gear burnishing machine includes a gear carrier (144) and a guide embodied by a rack (122) for cooperating to move a gear to be burnished into meshing relationship with a gear rack of the burnishing machine. A hopper (22) including a feed mechanism provides feeding of the gears to the carrier. Carrier movement moves the gears from the hopper to the machine as the guide rack aligns the gear teeth for meshing with the gear rack teeth. A retaining shaft of the carrier captures the gears between spaced retainers of the carrier as the gears move to the machine for burnishing. A retaining member (66) and a movable dog (84) of the feed mechanism cooperate in feeding gears to the carrier. After burnishing, an actuator including a pusher (204) moves the burnished gear off the guide to a delivery unit 14 including an inclined ramp (198).
