Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die in Fig. 1 und 2 der beiliegenden Zeichnung dargestellte Walze besteht aus einem Hohlkörper H und der inneren Achse A. Diese Achse ist nicht, wie bei den bisherigen Constructionen, nur an einer Stelle in der Mitte mit dem Hohlkörper verbunden, sondern an zwei Stellen aufserhalb der Mitte, wodurch eine wesentlich geringere Beanspruchung und daher gröfsere Ausnutzung des Walzenmaterials erzeugt wird. Dieser Vortheil macht sich besonders bei grofsen Breiten geltend, zumal dann, wenn die Walze nur zum Theil, und zwar einseitig ausgenutzt- wird, in der Art, dafs etwa die Actionslinie der Resultirenden von Biegungskräften nicht gerade durch die Tragstelle des Walzenmantels geht. In diesem Falle werden bei Vorhandensein von zwei Befestigungsstellen diese nur auf einfache Festigkeit beansprucht, wohingegen bei nur einer Tragstelle dieselbe in bedenklicher Weise auf zusammengesetzte Festigkeit beansprucht, die Ermittelung der angreifenden Momente recht verwickelt und somit auch die Bestimmung des richtigen Widerstandsmomentes vielfach eine Glückssache ist.The roller shown in Fig. 1 and 2 of the accompanying drawing consists of a hollow body H and the inner axis A. This axis is not, as in the previous constructions, only connected to the hollow body at one point in the middle, but at two points outside the center, which results in significantly less stress and therefore greater utilization of the roll material. This advantage is particularly evident in the case of large widths, especially when the roller is only partially used, namely on one side, in such a way that the action line of the resultant of bending forces does not go straight through the bearing point of the roller shell. In this case, if there are two fastening points, these are only stressed for simple strength, whereas with only one support point, the same stresses the composite strength in a questionable manner, the determination of the attacking moments is quite complicated and thus the determination of the correct resistance moment is often a matter of luck.

Claims (1)

Patent-Anspruch:Patent claim: Hohle Walze für Feinblechwalzwerke, Kalander u. dergl., dadurch gekennzeichnet, dafs ihre Achse nicht an einer Stelle in der Mitte, sondern an zwei Stellen aufserhalb der Mitte, mit dem Walzenmantel verbunden ist, zum Zwecke, Mantel und Achse der Walze für dieselbe Belastung schwächer halten zu können.Hollow roll for sheet mills, calenders and the like, characterized in that its axis not in one place in the middle, but in two places off the middle, is connected to the roll shell, for the purpose of being able to keep the shell and axis of the roll weaker for the same load.
