Abstract

The invention relates to a bearing for a centrally journalled one-piece continuous casting roller body. In order to provide a centrally journalled continuous casting roller body which is durable in rough working operation and permits a reduction of the roller diameter, it is proposed that the roller body be made in one piece and has in the middle two annular recesses, between which there is formed a bearing seat with a rotationally symmetrical curved surface which is received in a sectional bearing housing with a bearing face corresponding to the bearing seat. <IMAGE>

Description

Die Erfindung betrifft eine Lagerung für einen mittengelagerten Stranggießrollenkörper.The invention relates to a storage for a centrally stored Continuous casting roller bodies.

Geteilte Stranggießrollenkörper sind an sich für vorschiedene Zwecke bekannt.Split continuous casting roll bodies are per se for different Purposes known.

Es ist bekannt, in mittengelagerten Hollenkörpern geteilte Pendelrollenlager (DE-OS 27 13 652) bzw. Kugellager (DE-OS 29 11 624) einzusetzen. Bekannt ist auch eine Halbschalenlagerung im unteren Teil des Lagers (DE-OS 25 01 956).It is known to use split spherical roller bearings (DE-OS 27 13 652) or ball bearings (DE-OS 29 11 624) in center-mounted hollow bodies. A half-shell bearing in the lower part of the bearing is also known (DE-OS 25 01 956).

Nachteilig bei den bekannten Ausführungen ist, daß die Lagerelemente zweiteilig sein müssen; ferner sind Kugel- oder Pendelroi]enlager, insbesondere im Hüttenbetrieb durch starke Verschmutzung störanfällig.The disadvantage of the known designs is that the bearing elements must be in two parts; furthermore are spherical or pendulum roller bearings, especially in smelter operations prone to failure due to heavy soiling.

Aufgabe der Erfindung ict es, einen mittengelagerten Stranggießrollenkörper zu schaffen, der im rauhen Werksbetrieb widerstandsfähiger ist und eine Verringerung des Rollendurchmessers zuläßt.The object of the invention is to create a centrally mounted continuous casting roller body that can be used in rough factory operations is more resistant and allows a reduction in the roll diameter.

Zur Lösung dieser Aufgabe wird erfindungsgemäß eine Lagerung vorgeschlagen, wie sie im Patentanspruch 1 beschrieben ist·In order to achieve this object, a storage arrangement as described in claim 1 is proposed according to the invention is·

Weiterbildungen ergeben sich aus den ÜnteranSprüchen.Further training results from the subordinate requirements.

Die erfindungcgemäße Lagerung läßt aufgrund des kugelsegmentförmigen Lagersitzes eine Verringerung der Rollendurchmesser und damit eine bessere UnterStützung des Stranges durch die Verringerung des Rollenabstandes zu.The storage according to the invention can be due to the spherical segment-shaped Bearing seat a reduction of the roller diameter and thus a better support of the Strand by reducing the roller spacing.

Des weiteren ist in Folge dieser Lageranordnung eine Verringerung der Verschmutzung gegenüber bekannten Kugeloder Pendelrollenlager gegeben; Durch die wesentliche Vereinfachung des Lagersitzes sind erhebliche wirtschaftliehe Vorteile vorhanden·Furthermore, as a result of this bearing arrangement is a Reduced pollution compared to known ball or spherical roller bearings; By the essential Simplifying the bearing seat are significant economical Advantages available

Die erfindungsgemäße Lagerung weist schließlich gegenüber bekannten Rollenlagern eine höhere BelastungsmöglichkeitThe storage according to the invention finally has opposite known roller bearings have a higher load capacity

In den beigefügten Zeichnungen ist eine erfindungsgernäße-Lagerung für einen mittengelagerten einteiligen Stranggießrollenkörper schematisch dargestellt. In the accompanying drawings is a storage according to the invention shown schematically for a one-piece continuous casting roller body mounted in the center.

Die Lagerkugel 3 wird von einem an sich bekannten zweiteiligen Lagergehäuse 4 aufgenommen.The bearing ball 3 is received in a two-part bearing housing 4 known per se.

Für flüssigkeitsgekühlte Rollen sind die beiden Rollenteile des Rollenkörpers 1 mit mindestenr. einer Kühlflüssigkeit sbohrung 5 versehen. Der Rollenkörper 1 kann einteilig mit einer Kühlbohrung oder in Schweißkonstruktionen, wie z.B. einer Mantelrolle mit auf dem Umfang verteilten Kühlbohrungen versehen sein. Die Lagerung kann in bekannter Weise geschmiert oder wartungsfrei gestaltet werden. Die Oberfläche des kugelförmigen Lagersitzes kann in bekannter Weise, z.B. durch Hartverchromen, vergütet sein.For liquid-cooled roles, the two roller parts of the roller body 1 with at least. a coolant hole 5 provided. The roller body 1 can be made in one piece with a cooling bore or in welded constructions, such as a jacket roll with on the circumference distributed cooling holes. The storage can be lubricated in a known manner or designed to be maintenance-free will. The surface of the spherical bearing seat can be tempered in a known manner, e.g. by hard chrome plating be.
