摘要

Apparatus for the manufacture or working of straight or helically toothed, externally or internally toothed gears comprising a hyperboloidally or globoidally or similarly formed toothed tool, which has an abrasive or similar surface and which grips the workpiece over the entire width of the tooth. The axes of the workpiece and the tool are vertically spaced and crossed and the workpiece and the tool are each connected to a guide gear, which guide gears are coupled to one another. A control gearing is provided in the connection between the workpiece-tool pairing and the guide gear pairing.
