Abstract

Die Erfindung betrifft ein Walzwerk mit Arbeitswalzen und mehrteiligen Stützwalzen, bestehend aus einem Grundkörper mit mehreren darauf in dessen Längsrichtung nebeneinander angeordneten Wälzlagern, die mit ihren Außenringen eine die Wälzlager umgreifende Hülse drehbar abstützen, deren Außenoberfläche den Walzballen der Stützwalze bildet, wobei der Grundkörper um seine Längsachse verdrehbar ist und in etwa der Breite der Wälzlager entsprechende zylindrische Abschnitte aufgeteilt ist, deren parallel zueinander verlaufende Zylinderachsen jeweils benachbarter Abschnitte zueinander versetzt sind. Dabei liegt die Hülse (10) mit ihrer Innenoberfläche allseitig an den Außenoberflächen der Außenringe der Wälzlager (9) an und erhält dadurch eine Exzentrizität, die sich aus der Exzentrizität der Abschnitte (3 bis 6) des Grundkörpers (1) vermindert durch den Rück-Biegeeinfluß der Hülse (10) ergibt.

Figure 00000001
The invention relates to a rolling mill with work rolls and multi-part backup rolls, consisting of a base body with a plurality of roller bearings arranged next to one another in the longitudinal direction thereon, which with their outer rings rotatably support a sleeve encompassing the roller bearings, the outer surface of which forms the roll barrel of the backup roller, the base body around its The longitudinal axis can be rotated and cylindrical sections corresponding to the width of the roller bearings are divided, the cylinder axes of which are parallel to one another and are offset in each case from adjacent sections. The inner surface of the sleeve (10) bears on all sides against the outer surfaces of the outer rings of the roller bearings (9) and thereby receives an eccentricity which is reduced by the eccentricity of the sections (3 to 6) of the base body (1) due to the back Bending influence of the sleeve (10) results.
