Abstract: A method and an apparatus for shaving, rolling or similar ones of the tooth flanks of gears in which a gearlike workpiece which is to be worked is supported stationarily, however, rotatingly and is in a two flank meshing engagement with a toothlike tool. The tool carries out a rectilinear back-and-forth feed movement in a plane, which is parallel with respect to the workpiece axis, a plunge movement perpendicularly with respect to the workpiece axis and a swivelling movement about an axis which is directed transversely with respect to the feed direction. To produce crowned tooth flanks, the plunge feed and the swivelling movement of the tool is changed independently from one another in dependency of the respective position of the tool along the feed path. A rocking device is provided on which is arranged the tool and which also takes part in the back-and-forth feed movement and which furthermore can be driven pivotally about an axis which extends transversely with respect to the feed direction.
