Rotary drive of reciprocating roll passes of a cold pilger rolling mill

摘要

In a method for adjusting a rolling curve of drive pinions of ring rollers to a neutral zone within a tapering portion of a roll pass of the ring rollers of a cold pilger rolling mill, circular pinions are arranged and secured eccentrically on a roller axis of the ring roller. The circular pinions are driven by sine-shaped tooth racks.
