TLDR
In this article, a method of grinding bevel gear teeth in an intermittent indexing process using a single grinding wheel provided with different bevel angles to produce the desired grinding wheel radii is described.Abstract:
Disclosed is a method of grinding bevel gear teeth in an intermittent indexing process using a single grinding wheel provided with different bevel angles (α) to produce the desired grinding wheel radii (R): one flank is machined during grinding in downward generation as far as a first turning point, another flank is produced in upward generation as far as a second turning point, and machine settings are so adjusted in the turning points as to ensure a correct pressure angle and correct flank topography during the generating process, irrespective of the different bevel angles (α). The process combines the advantages of the known completing process, by which both flanks can be ground at the same time at the cost of imposing a particular wheel body geometry with conical teeth, with those of the known two-track process for grinding both flanks with a double grinding head, by which various additional correction factors can be introduced to optimize the flank shape for convex and concave flanks.read more
