Abstract
A gear shaping machine is provided. The gear shaping machine includes a pair of horizontally reciprocating gear shaping heads mounted to a column. Each gear shaping head includes a spindle assembly including an integral rotary drive for indexing the spindle. The spindle assembly is carried by a spindle slide. The spindle slide also carries a plurality of bearing blocks to allow for sliding movement of the gear shaping head relative to rails mounted on the column. A linear drive arrangement is operably coupled between each gear shaping head and the column. The linear guide arrangement allows for controlled linear translation of each gear shaping head independently of one another. Each gear shaping head also includes a back-off mechanism for independently moving the spindle assembly toward the workpiece during a cutting stroke and away from the workpiece during a return stroke of each gear shaping head.
