Description

Walzgerüst. Die Einführung der Rollen und Kugellager an Stelle der Gleitlager bei den Walzwerken der Eisen- und Metallindustrie bietet doch mehr Schwierigkeiten, als man anfangs glaubte. Bei den gebräuchlichen angegossenen großen Zapfen der Walzen war für die Unterbringung der Rollenlager in den Mitten der Walzenständer meistens zu wenig Platz. Man war gezwungen, entweder aus Fertigkeitsgründen kleine stählerne Zapfen an den «Talzen anzubringen oder die Rollenlager der übereinanderliegenden Walzen gegenseitig zu versetzen. Beide Bauarten haben ihre Nachteile. Der Ersatz von in dem Kleeblatt abgenutzten eingesetzten stählernen Zapfen ist schwierig, und bei der Bauart mit versetzten Lagern werden die angegossenen Walzenzapfen durch die größere Länge gegen Abbrechen wesentlich geschwächt und führen leicht zu Brüchen.Roll stand. The introduction of rollers and ball bearings in place of the Plain bearings in the rolling mills of the iron and metal industry offer more difficulties, than was initially believed. With the common cast-on large journals of the rollers was mostly used to accommodate the roller bearings in the middle of the roll stands too little space. One was forced to use small steel ones, either for reasons of skill To attach pegs to the valley or the roller bearings of the superimposed To offset rollers mutually. Both types have their disadvantages. The replacement of worn steel pegs inserted in the shamrock is difficult, and in the design with staggered bearings the cast roll neck considerably weakened by the greater length against breaking off and lead easily to breaks.

Diese Nachteile werden behoben durch in den Einbaustücken der Walzerständer angebrachte feststehende Lagerzapfen, auf welchen die Rollen- und Kugellager arbeiten. Konische Büchsen umschließen die Rollen- und Kugellager, und die Arbeitswalzen werden auf diese konischen Büchsen aufgeschoben. Der Antrieb der Walzen geschieht durch Spindeln aus Rund- oder Vierkanteisen, «-elche durch die hohlen, feststehenden Zapfen und die Arbeitswalzen hindurchgeschoben werden. Bei einer eintretenden Abnutzung sind diese Spindeln rasch und leicht zu ersetzen. Durch das Fehlen der Walzenzapfen können auch keine Brüche von solchen entstehen mit ihren oft schweren Folgen.These disadvantages are remedied by in the chocks of the waltz stand attached fixed bearing journals on which the roller and ball bearings work. Conical bushings enclose the roller and ball bearings, and the work rolls are pushed onto these conical bushings. The rollers are driven by Round or square iron spindles through the hollow, fixed tenons and the work rolls are pushed through. In the event of wear and tear these spindles can be replaced quickly and easily. Due to the lack of the roll neck no fractures can arise from such, with their often serious consequences.

Die Zeichnung stellt den Aufriß eines Duowalzgerüstes im Schnitt dar.The drawing shows a sectional elevation of a two-high rolling stand.

In dem Walzenständer a sind vertikal verschiebbar die feststehenden hohlen Lagerzapfen b untergebracht, deren Gleitstücke c, d paarweise cc und dd, rechts und links, starr auf bekannte Weise miteinander verbunden sind. Auf den Lagerzapfen b ruhen die bekannten Wälzlager e und f (Rollen- und Kugellager) zur Aufnahme der vertikalen und horizontalen Kräfte. über die Rollen und Kugeln wird die konische Büchse g geschoben., so daß das Lager in sich vollständig ist. Auf diese Büchse g werden nun die an den Enden konisch ausgebohrten Arbeitswalzen h und i leicht aufgedrückt, um absolut sicher gelagert zu sein. Damit die Walzen h und i auch angetrieben werden können, werden die Spindeln k aus Rund- und Vierkanteisen durch die hohlen Lagerzapfen b in die entsprechend aitsgearbeiteten Löcher der Walzen h und i hindurchgesteckt.In the roller stand a, the stationary hollow bearing journals b are accommodated so as to be vertically displaceable, the sliding pieces c, d of which in pairs cc and dd, right and left, are rigidly connected to one another in a known manner. The known roller bearings e and f (roller and ball bearings) to absorb the vertical and horizontal forces rest on the bearing journals b. The conical sleeve g is pushed over the rollers and balls, so that the bearing is complete in itself. The work rolls h and i, which are conically drilled out at the ends, are then lightly pressed onto this sleeve g in order to be stored absolutely securely. So that the rollers h and i can also be driven, the spindles k made of round and square iron are inserted through the hollow bearing journals b into the correspondingly machined holes in the rollers h and i .
