An apparatus for manufacturing or machining externally toothed gears using a hyperboloidally or similarly formed, internally or externally toothed tool with abrasive tooth flanks. The tool and workpiece roll on one another about respective axes which cross at a distance. The tool has a sufficient axial dimension so that it is in engagement with the workpiece teeth from one side surface to the other of the workpiece. The workpiece and tool are coupled with guide wheel pairs. Each guide wheel pair runs with potential for backlash, but the overall gearing is such that no such backlash can occur. |
