Abstract

See full text

A method for producing a ring with a toothing may involve (a) ring rolling a pre-ring to form a ring blank, (b) introducing a pre-toothing into the ring blank to form a pre-toothed ring, wherein the pre-toothing has teeth with a first tooth height, (c) heating, quenching, and tempering the pre-toothed ring to form a heat-treated pre-toothed ring, and (d) finish-toothing the heat-treated pre-toothed ring to form a ring with a toothing. The toothing may have teeth with a second tooth height that is greater than the first tooth height. Further, the introducing of the pre-toothing or the finish-toothing of the heat-treated pre-toothed ring may be performed by way of a metal machining process.
