Lager für Walzwerke.
In Walzwerken werden bisher ausnahmslos Gleitlager verwendet. Die Zapfen der Walzen bestehen grösstenteils aus Gusseisen, zum Teil aus Stahlguss. Die Lagerschalen werden zumeist aus Bronze oder aus Weissmetall hergestellt, in seltenen Fällen, und zwar bei leichteren Walzwerken, auch in Holz ausgeführt.
Alle diese Gleitlager haben den bekannten Nachteil, dass die Gleitflächen sowohl des Lagers als auch des Zapfens rasch verschleissen, wodurch während des Walzprozesses die relative Lage der Walzen gegeneinander verändert und die Abmessungen des WalzstUckes verschieden werden. Zur Ausgleichung der Abnutzung müssen daher die Lager häufig nachgestellt werden.
Gemäss der vorliegenden Erfindung sollen an Stelle der sich stark abnutzenden Gleitlager Rollager mit sehr geringem Verschleiss verwendet werden. Die harten Stahlflächen der Zapfenlager nutzen sich praktisch nicht ab, daher bleibt die Lage der Walzen gesichert und alle Walzstücke im Profil von denselben Abmessungen. Alle Arbeiten für die
EMI1.1
teile für den Betrieb ergeben.
Durch die Anwendung der wälzenden Reibung statt gleitender wird sehr viel Arbeit erspart, da gerade bei Walzwerken infolge der grossen Lageranzahl die Lagerreibung oft mehr als die Hälfte der Walzarbeit erfordert.
In Zeiten von Bronzcmangei sind aus Stahl gefertigte Walzlager ein Mittel, den Verbrauch jeder Lagerkomposition (Sparmetalle) auszuschalten.
Die Ausführung der Rollager erfolgt in geschlossener Art als Rollen-oder Kugellager, abweichend von den bisherigen Ausführungen der Lager als offene Halbschalen.
Mittels der Rollager wird auch eine umwälzende Schmierung ermöglicht. Das geschlossene Lagergehäuse schützt den Zapfen vor unmittelbarer Bestrahlung durch Wärme, vor der Spülwirkung des Kühlwassers und es wird dadurch auch verhindert, dass der abblätternde Walzensinter (Hammerschlag) in das Lager eindringt.
EMI1.2
PATENT-ANSPRÜCHE :
1. Lager für Walzwerke, dadurch gekennzeichnet, dass es zur Vermeidung des Walzennachstellens während des Walzens als den Zapfen vollumschliessendes Rollen-oder Kugellager ausgebildet ist, dessen Lagerflächen aus hartem Stahl oder ähnlichem, fast unabnutzbarem Material hergestellt sind.

Bearings for rolling mills.
So far, plain bearings have been used in rolling mills without exception. The journals of the rollers are largely made of cast iron and some of cast steel. The bearing shells are mostly made of bronze or white metal, in rare cases, in lighter rolling mills, also made of wood.
All these plain bearings have the known disadvantage that the sliding surfaces of both the bearing and the journal wear out quickly, as a result of which the relative position of the rollers against each other changes during the rolling process and the dimensions of the rolled piece are different. To compensate for wear, the bearings must therefore be readjusted frequently.
According to the present invention, roller bearings with very little wear are to be used in place of the heavily worn plain bearings. The hard steel surfaces of the journal bearings practically do not wear out, so the position of the rolls remains secure and all rolled sections in the profile have the same dimensions. All work for the
EMI1.1
parts for operation.
The use of rolling friction instead of sliding friction saves a great deal of work, since especially in rolling mills, due to the large number of bearings, bearing friction often requires more than half the rolling work.
In times of bronze mangei, roller bearings made of steel are a means of eliminating the consumption of every bearing composition (saving metals).
The roller bearings are designed in a closed manner as roller or ball bearings, in contrast to the previous versions of the bearings as open half-shells.
Circulating lubrication is also made possible by means of the roller bearings. The closed bearing housing protects the journal from direct exposure to heat, from the flushing effect of the cooling water, and this also prevents the flaking roller sinter (hammer blow) from penetrating the bearing.
EMI1.2
PATENT CLAIMS:
1. Bearing for rolling mills, characterized in that it is designed as a roller or ball bearing fully encompassing the pin, the bearing surfaces of which are made of hard steel or similar, almost indestructible material, in order to avoid roller readjustment during rolling.
