Abstract

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.

Figure 00000001
The invention relates to a rolling machine with quick exchange of work rolls (1) from the fastening of their pins (7, 8) in the supporting lateral bearing pins (2, 3), which are arranged in machine frames (4), one of which is each by means of a gear (5 ) is connected to the main drive (6) of the machine. The problem of the rapid exchange of work rolls (1) is solved in that the end faces of the pins (7, 8) of the work rolls (1) are provided with non-continuous end springs (9, 10) which are inserted into corresponding opposite non-continuous end grooves (11, 12) engage in lateral bearing journals (2, 3), the zones of their engagement contact being radially covered by axially displaceable rings (13).
