Abstract (en)
[origin: EP1203622A2] The rolling curve of the drive pinions of ring rollers are adapted to the neutral zone in decreasing caliber of the ring rollers of a cold pilger rolling mill, by using circular pinions, which are positioned eccentrically on and fastened to the roller shaft. Sinusoidal toothed racks are used to drive pinions and ring rollers. If circular eccentric pinions are used, which mesh with sinusoidal racks, for parameters can be adapted to actual roller dimensions:- roller diameter, pinion reference circle, eccentricity, angular position of eccentricity relative to entrance dead center of roller stand.
