2096024 9209395 PCTABS00013 A tool for producing crown wheels by means of a generating process comprises a disc which is rotatable about its axis, with machining elements which are provided on the periphery thereof and the cutting edges of which lie in the outer surface of a profile determining the shape of the teeth of a crown wheel to be produced with the tool, said profile extending essentially helically over the periphery of the disc. In each cross-section of the helical profile the outer contour (25) of the cross-section is at least composed of a part of the outer contour of the tooth profile of an imaginary gear wheel (23) with involute teeth and preferably straight lines connecting thereto, in such a way that in the case of each of the teeth (22) with a tooth tip and two tooth flanks bounded by the outer contour (25) of the cross-section the distance between each of the two tooth flanks and a line at right angles to the axis of rotation of the tool and passing through the tooth tip remains the same or increases from the tooth tip to the axis of rotation of the tool.
