Abstract
A gear shaping machine for the manufacture or machining of gears having a shaping tool and a shaping head bearing the shaping tool, where the shaping head is movable transversely to the shaping direction for the delivering and lifting of the shaping tool to the workpiece. A direct drive is provided for this purpose which moves the shaping head transversely to the shaping direction. Furthermore a corresponding method for the manufacture or machining of gears is described.
Claims20
A gear shaping machine for the manufacture or machining of gears comprising:
- a shaping tool;
- a shaping head bearing the shaping tool, wherein the shaping head is movable transversely to the shaping direction for the delivering and lifting of the shaping tool to the workpiece, and
- a direct drive that moves the shaping head transversely to the shaping direction.
A method for the manufacture or finishing of gears using a gear shaping machine, comprising moving a shaping head bearing a shaping tool transversely to a shaping direction by a direct drive for the delivery and lifting of the shaping tool to a workpiece.
A gear shaping machine for the manufacture or machining of gears comprising:
- a shaping tool;
- a shaping head bearing the shaping tool, wherein the shaping head is movable transversely to the shaping direction for the delivering and lifting of the shaping tool to the workpiece,
- a direct drive that moves the shaping head transversely to the shaping direction wherein the direct drive drives an eccentric shaft which moves the shaping head transversely to the shaping direction via an intermediate lever;
- and
- a controller to electronically adjust the direct drive to vary a path of the shaping tool differently in a working stroke and in a reverse stroke, and to vary the path of the shaping tool differently for rough machining as compared to finish machining.
