Abstract

Apparatus for the manufacture or machining of straight of helically toothed gears with a hyperboloidally or globoidally or similarly formed toothed tool, which has an abrasive or similar surface and which has such an axial dimension that it covers the entire width of the workpiece tooth system. The axes of the workpiece and the tool cross and the workpiece and the tool are coupled to a guide gearing. The workpiece-tool pairing and the guide gearing each have their own (separate) crossed-axes point. Interchangeable gears can be provided between the workpiece-tool pairing. According to a different embodiment, the axis of the guide gearing and the workpiece axis are arranged parallel to one another, also to another axis of the guide gearing and the tool axis. The parallel axes are coupled to one another through master gears and interchangeable gears.
