摘要： A machine for pressure forming teeth and the like on rotary workpieces including workpiece supporting means for rotatably supporting a workpiece, a pair of tool holders for tooth forming tools mounted for rectilinear movement in spaced, substantially parallel paths transversely of and on opposite sides of the rotary axis of the workpiece supported by the workpiece support means, and a drive assembly for simultaneously driving the tool holders in opposite directions along their respective paths. The drive assembly includes: (1) a pair of driving racks, one of the driving racks being secured to one of the tool holders and disposed parallel to the path of movement thereof, and the other of the driving racks being secured to the other of the tool holders and disposed parallel to the path of movement thereof, (2) a pair of spaced, rotatable shafts extending substantially transversely of the driving racks, one of the shafts being drivingly engaged with one of the racks to cause rectilinear movement of the associated tool holder along its path of movement in response to rotation of the shaft, the other of the shafts being drivingly engaged with the other of the racks to cause rectilinear movement of the associated tool holder along its path of movement in response to rotation of the shaft, (3) a gear train engaged between the shafts to cause synchronous simultaneous rotation of the shafts and corresponding movement of the tool holders in opposite directions, and (4) power means for driving the shafts. Selectively adjustable deflection controlling means is provided for controlling deflection of the tool holders during a pressure forming operation.
