Abstract

A gear mechanism (6) for a rolling mill drive includes at least one involute cylindrical gear tooth system between at least two intermeshing gear wheels (3) with asymmetrical gearing. The normal pressure angle of the load-bearing tooth flanks (5) of the gear wheels (3) is greater than 20° and less than or equal to 30°, and the normal pressure angle of the trailing flanks (4) of the gear wheels is greater than or equal to 14° and less than 22°. A rolling mill drive has a gear mechanism (6) of this type, and the gear mechanism (6) is used as a rolling mill gear mechanism.
