Abstract
Method and an apparatus for the profiling of single-gear or multiple-gear grinding worms for grinding tooth profiles in accordance with the principle of continuous diagonal hob grinding. A grinding worm is divided into at least two axial segments wherein one segment remains unmodified and a second segment receives, by means of special profiling methods, modifications of the spiral faces for the generation of tooth face modifications. The main attribute of these profiling methods is additional movements, which are superimposed on the disk-shaped profiling tool and/or the grinding worm in relation to a given profiling lift position, and which result in the modifications of the grinding worm faces that are mapped onto the faces of the toothed wheel work during subsequent diagonal hob grinding across a grinding worm segment profiled in this manner. Additional movements designed to generate the modifications include, in particular, pivoting of the profiling tool around an axis (F) or pivoting the grinding worm around an axis (C) during profile dressing, as well as continuous incline change during line-by-line profiling.
