Abstract (en)

The front parts of the pegs (7, 8) of the working rolls (1) of a rolling machine are provided with projections (9, 10) that grip the corresponding opposite front nuts (11, 12) arranged in off-center bearing journals (2, 3). The zones of contact are covered by axially moving rings (13).

Abstract (de)

Die Erfindung betrifft eine Walzmaschine mit Schnellaustausch von Arbeitswalzen (1) von der Befestigung deren Zapfen (7, 8)in den tragenden seitlichen Lagerzapfen (2, 3), die in Maschinenrahmen (4) angeordnet sind, von denen jeweils einer mittels Getriebe (5) mit dem Hauptantrieb (6) der Maschine verbunden ist. Das Problem des Schnellaustausches von Arbeitswalzen (1) ist dadurch gelöst, daß die Stirne der Zapfen (7, 8) der Arbeitswalzen (1) mit nicht durchlaufenden Stirnfedern (9, 10) versehen sind, die in korrespondierende gegenüberliegende nicht durchlaufende Stirnnuten (11, 12) in seitlichen Lagerzapfen (2, 3) eingreifen, wobei die Zonen deren Eingriffkontaktes durch axial verschiebbare Ringe (13) radial überdeckt werden. <IMAGE>
