Title:
METHOD OF GRINDING THE TEETH OF SPIRAL-TOOTHED BEVEL GEAR WHEELS
Document Type and Number:
WIPO Patent Application WO1996035541
Kind Code:
A3
Abstract:
Disclosed is a method of grinding bevel gear teeth in a single-indexing process using a single grinding wheel provided with different bevel angles ( alpha ) to produce the desired grinding wheel radii (R): one flank is machined during grinding in downwards hobbing as far as a first turning point, another flank is produced in upwards hobbing as far as a second turning point, and machine settings are so adjusted in the turning points as to ensure a correct engagement angle and correct flank topography during the hobbing process, irrespective of the different bevel angles ( alpha ). 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 optimise the flank shape for convex and concave flanks.
