The bodies electrically and thermally insulate the shell from the shaft.

Description

ROLLGANGSROLLE, INSBESONDERE FÜR DEN TRANSPORT VON OFENWARMEM, METALLISCHEM BANDMATERIALROLLER ROLLER, ESPECIALLY FOR THE TRANSPORT OF WARM OVEN, METAL I SC H EM BAND MATERIAL
Die Erfindung betrifft eine Rollgangsrolle, insbesondere für den Transport von ofenwarmem, metallischem Bandmaterial, Gießsträngen aus Stahl u. dgl., mit einer Rollenwelle und einem auf der Rollenwelle zumindest an den Rollenenden gelagerten Rollenmantel.The invention relates to a roller table roller, in particular for the transport of warm, metallic strip material, cast strands of steel and. Like., With a roller shaft and a roller shell mounted on the roller shaft at least at the roller ends.
Bei generellen Unterschieden des elektrischen Potentials zwischen einem metallischen Produkt und einer Rollgangsrolle können elektrische Ströme und Funkenbildung Oberflächenfehler im herzustellenden Material verursachen.If there are general differences in the electrical potential between a metallic product and a roller table roller, electrical currents and sparks can cause surface defects in the material to be manufactured.
Es ist bekannt ( DE 24 26 135 C2), eine Rollgangsrolle für den Transport von Walzgut vorzuschlagen, die den Stößen des Walzgutes widerstehen kann. Es ist jedoch nicht daran gedacht, dass solche Rollgangsrollen auch elektrischen Strömen und Funkenbildung ausgesetzt sind, die das Walzgut beschädigen können.It is known (DE 24 26 135 C2) to propose a roller table roller for the transport of rolling stock which can withstand the impacts of the rolling stock. However, it is not contemplated that such roller table rollers are also exposed to electrical currents and sparking that can damage the rolling stock.
Der Erfindung liegt daher die Aufgabe zugrunde, derartige elektrische Ströme und Funkenbildungen zu unterbinden, so dass die erwähnten Schäden nicht mehr auftreten können.The invention is therefore based on the object of preventing such electrical currents and sparking, so that the damage mentioned can no longer occur.
Die gestellte Aufgabe wird erfindungsgemäß dadurch gelöst, dass der Rollen- mantel zumindest an den Rollenenden jeweils elektrisch und / oder thermisch isoliert auf der Rollenwelle gelagert ist. Eine solche Rollgangsrolle eignet sich für Rollgänge oder Rollgangsteile im Bereich induktiver Erwärmung und induzierter elektrischer Felder sowie bei generellen Unterschieden des elektrischen Potentials zwischen einem Walz- oder Stranggießprodukt und Rollgangsrolle, wo elektrische Ströme und Funkenbildung Oberflächenfehler verursachen können. Vorteilhafterweise kann eine solche Rollgangsrolle auch eingesetzt werden, um den Wärmeaustausch durch Wärmeleitung zwischen dem durch das Produkt erwärmten Rollenmantel mit der in der Regel gekühlten Rollenwelle (Rollenachse) weitgehend zu unterbinden.The object is achieved according to the invention in that the roller jacket is mounted on the roller shaft in an electrically and / or thermally insulated manner at least at the roller ends. Such a roller table roller is suitable for roller tables or roller table parts in the area of inductive heating and induced electric fields as well as for general differences in the electrical potential between a rolled or continuous casting product and roller table roller, where electrical currents and sparking can cause surface defects. Such a roller table roller can advantageously also be used in order to largely prevent the heat exchange by heat conduction between the roller jacket heated by the product and the roller shaft (roller axis), which is generally cooled.
Die Erfindung ist dadurch weitergebildet, dass zwischen dem Rollenmantel an den Rollenenden und der Rollenwelle jeweils über den Umfang verteilt angeordnete, einzelne Isolierkörper oder ein einstückiger, ringförmiger Isolierkörper vorgesehen sind. Die Isolierkörper können dabei zur Zentrierung des Rollen- mantels auf der Rollenwelle und / oder zur Drehmomentübertragung eingesetzt werden.The invention is further developed in that individual insulating bodies or a one-piece, ring-shaped insulating body are provided between the roller jacket at the roller ends and the roller shaft, each distributed over the circumference. The insulating bodies can be used for centering the roller shell on the roller shaft and / or for torque transmission.
Eine Ausgestaltung besteht hierbei darin, dass die über den Umfang verteilt angeordneten, einzelnen Isolierkörper aus Profilstäben bestehen. Das Profil kann aus Rundstäben, Flach- oder Rechteckmaterial oder aus anderen Querschnittsformen gebildet sein. Der Werkstoff für solche Profilstäbe kann aus Keramik oder anderen Isolationswerkstoffen bei entsprechender Festigkeit gewählt werden.One embodiment here is that the individual insulating bodies, which are arranged distributed over the circumference, consist of profiled bars. The profile can be formed from round bars, flat or rectangular material or from other cross-sectional shapes. The material for such profile bars can be selected from ceramic or other insulation materials with appropriate strength.
Ein weiterer Vorteil ergibt sich dadurch, dass die Profilstäbe zusammen mit Lagerringen gegenüber der Rollenwelle und dem Rollenmantel axial gesichert sind.Another advantage results from the fact that the profiled bars, together with bearing rings, are axially secured with respect to the roller shaft and the roller jacket.
Zur Verhinderung einer axialen Verschiebung ist z.B. vorteilhaft, dass die axiale Sicherung aus an den Stirnseiten der Lager aufgeschweißten Blechringen besteht.To prevent axial displacement, e.g. It is advantageous that the axial securing consists of sheet metal rings welded onto the end faces of the bearings.
Währenddem der Rollenmantel und die Rollenwelle grundsätzlich voneinander getrennt sind und ausschließlich über die Isolationskörper in Verbindung ste- hen, kann mittels der axialen Sicherung ein Loslager und ein Festlager zwi- sehen dem Rollenmantel und der Rollenwelle gebildet sein. Dadurch können Wärmespannungen und Wärmedehnungen aufgefangen werden.While the roller shell and the roller shaft are fundamentally separated from each other and are only connected via the insulation body, the axial securing means that a floating bearing and a fixed bearing can see the roller shell and the roller shaft be formed. This allows thermal stresses and thermal expansions to be absorbed.
Grundsätzlich entsteht ein weiterer Vorteil dadurch, dass die Isolierkörper den Rollenmantel auf der Rollenwelle zentrieren und gleichzeitig Drehmoment- Übertragungs-mittel bilden. Dadurch wird eine kompakte für die notwendige Kraftübertragung zweckmäßige Einheit einer Rollgangsrolle geschaffen.Basically, another advantage arises from the fact that the insulating bodies center the roller casing on the roller shaft and at the same time form torque transmission means. This creates a compact unit of a roller table roller that is expedient for the necessary power transmission.
Eine alternative Ausführungsform sieht vor, dass der Rollenmantel in mehrere, beabstandet auf der Rollenwelle angeordnete Rollenmantel-Abschnitte mit je- weils über den Umfang verteilt angeordneten, die Rollenwelle zentrierenden und das Antriebsdrehmoment übertragenden Isolierkörpern gegliedert ist. Dabei sind die Rollenmantel-Abschnitte von der Rollenwelle getrennt und werden ausschließlich über die beschriebenen Isolierkörper verbunden.An alternative embodiment provides that the roller jacket is divided into a plurality of roller jacket sections, spaced apart on the roller shaft, each with insulating bodies distributed over the circumference, centering the roller shaft and transmitting the drive torque. The roller jacket sections are separated from the roller shaft and are only connected via the insulating bodies described.
Nach einer weiteren Alternativen ist der Isolierkörper als Kegellager ausgeführt, dessen Konus-Innenring und / oder dessen Konus-Außenring und / oder dessen Kegelrollen jeweils Isolierkörper bilden. Dabei kann wegen der kurzen Rollenmantel-Abschnitte das durch Erwärmung und Längenausdehnung in axialer Richtung entstehende Spiel vernachlässigt werden, so dass keine Anordnung in Los- und Festlager erforderlich ist. Dabei werden besonders elektrische Ströme in Achsrichtung unterbunden.According to a further alternative, the insulating body is designed as a tapered bearing, the inner ring of the cone and / or the outer ring of the cone and / or the tapered rollers of which each form insulating bodies. Due to the short roller jacket sections, the play resulting from heating and longitudinal expansion in the axial direction can be neglected, so that no arrangement in floating and fixed bearings is required. Electric currents in the axial direction in particular are prevented.
Nach der weiteren Erfindung wird die durch Erwärmung des Rollenmantels vergrößerten Spiele im Passsitz der Isolationskörper dadurch kompensiert, dass der Konus-Innenring axial verschiebbar und unter Federkraft auf der Rollenwelle anstellbar ist.According to the further invention, the play in the fit of the insulation bodies, which is increased by heating the roller jacket, is compensated for by the fact that the inner cone ring is axially displaceable and adjustable under spring force on the roller shaft.
Die Neigung des Konus ist dabei so zu wählen, dass aufgrund der Längenausdehnung des Rollenmantels der Außenkonus auf dem Innenkonus eine andere Position einnimmt und damit die Aufweitung des Durchmessers weitgehend ausgleicht. Dafür ist eine praktische Ausführungsform dadurch gegeben, dass der Konus- Innenring auf der Rollenwelle axial mittels Tellerfedern, die gegen einen Wellenabsatz abgestützt sind, gegen den hohlen mit dem Rollenmantel fest verbundenen Konus-Außenring, verschiebbar ist. Dadurch wird das Spiel kontinu- ierlich durch die Federkraft eliminiert.The inclination of the cone is to be selected so that the outer cone on the inner cone assumes a different position due to the length of the roller shell and thus largely compensates for the expansion of the diameter. For this purpose, a practical embodiment is provided in that the cone inner ring on the roller shaft can be axially displaced against the hollow cone outer ring firmly connected to the roller shell by means of disc springs which are supported against a shaft shoulder. As a result, the play is continuously eliminated by the spring force.
Eine andere Gestaltung sieht noch vor, dass ein Rollenmantel-Abschnitt jeweils am Rollenende in einem Kegellager und etwa mittig mittels der über den Umfang verteilten Isolierkörper gelagert ist.Another design provides that a roller jacket section is mounted at the roller end in a tapered bearing and approximately in the middle by means of the insulating bodies distributed over the circumference.
In der Zeichnung sind Ausführungsbeispiele der Erfindung dargestellt und werden nachfolgend näher erläutert.Exemplary embodiments of the invention are shown in the drawing and are explained in more detail below.

Die Rollgangsrolle dient z.B. zum Transport von Bandmaterial, das aus einem Behandlungsofen austritt oder zum Transport von Gießsträngen, z.B. von Dünnsträngen. Der grundsätzliche Aufbau umfasst einen Rollenmantel 1. Der zumindest an den Rollenenden 2 und 3 jeweils elektrisch und / oder thermisch isoliert auf der Rollenwelle 4 gelagert ist (Fig. 1 und 1 A als erste Ausführungsform).The roller table roller serves e.g. for transporting strip material that emerges from a treatment furnace or for transporting casting strands, e.g. of thin strands. The basic structure comprises a roller casing 1, which is mounted at least on the roller ends 2 and 3, in each case electrically and / or thermally insulated, on the roller shaft 4 (FIGS. 1 and 1A as the first embodiment).
Die Isolation entsteht dadurch, dass zwischen dem Rollenmantel 1 an den Rollenenden 2 und 3 und der Rollenwelle 4 über den Umfang verteilt angeordnete, einzelne Isolierkörper 5 (Fig. 1 , 1 A; Fig. 2, 2A und Fig. 3, 3A) vorgesehen sind. Alternativ kann auch ein einstückiger, ringförmiger Isolierkörper 6 (Fig. 4) vorgesehen werden.The insulation arises from the fact that individual insulating bodies 5 (FIGS. 1, 1A; FIGS. 2, 2A and 3, 3A) are arranged between the roller jacket 1 at the roller ends 2 and 3 and the roller shaft 4 and are distributed over the circumference are. Alternatively, a one-piece, annular insulating body 6 (FIG. 4) can also be provided.
Die über den Umfang verteilt angeordneten, einzelnen Isolierkörper 5 bestehen aus Profilstäben 7, die einen runden, flachen, rechteckigen oder polygonalen Querschnitt besitzen. Die Profilstäbe 2 bestehen aus Keramik oder anderen, mit isolierenden Wirkungen verbundenen Werkstoffen.The individual insulating bodies 5 distributed over the circumference consist of profiled bars 7, which have a round, flat, rectangular or polygonal cross section. The profile bars 2 consist of ceramic or other materials with insulating effects.
Die Rollenwelle 4 ist mit Lagerabsätzen 8 und 9 ausgestattet und wird mittels Kühlmedien, das durch einen Kemkanal 10 strömt, gekühlt. Die Profilstäbe 7 sind zusammen mit Lagerringen 11 und 12 auf einem Wellenabsatz 13 axial gesichert. Die axiale Sicherung besteht aus an den Stirnseiten 14 und 5 auf- geschweißten Blechringen 17, die jeweils an den zusammen mit den Profilstäben 7 gebildeten Lagern 16 angebracht sind. Diese Lager 16 können als ein Loslager 16a und ein Festlager 16b zur Wärmedehnung gestaltet sein.The roller shaft 4 is equipped with bearing shoulders 8 and 9 and is cooled by means of cooling media which flows through a core channel 10. The profile bars 7 are axially secured together with bearing rings 11 and 12 on a shaft shoulder 13. The axial securing consists of sheet metal rings 17 welded onto the end faces 14 and 5, which are each attached to the bearings 16 formed together with the profiled bars 7. These bearings 16 can be designed as a floating bearing 16a and a fixed bearing 16b for thermal expansion.
Die Isolierkörper 5 zentrieren den Rollenmantel 1 auf der Rollenwelle 4 und bil- den gleichzeitig durch Form- und / oder Kraftschluss ein Drehmoment- Übertragungs-mittel. In einer zweiten Ausführungsform (Fig. 2, 2A) ist der Rollenmantel 1 in mehrere, beabstandet auf der Rollenwelle 4 angeordnete Rollenmantel-Abschnitte 1a, 1 b, 1c, 1d usw. gegliedert, die jeweils wieder mittels der Isolierkörper 5 zur Rollenwelle 4 zentrieren und das Antriebsdrehmoment übertragen.The insulating bodies 5 center the roller casing 1 on the roller shaft 4 and at the same time form a torque transmission means by positive and / or non-positive connection. In a second embodiment (FIGS. 2, 2A), the roller shell 1 is divided into a plurality of roller shell portions 1a, 1b, 1c, 1d, etc., spaced apart on the roller shaft 4, each centering again on the roller shaft 4 by means of the insulating body 5 and transmit the drive torque.
Gemäß einer dritten Ausführungsform (Fig. 3 und 3A) ist der Isolierkörper 5 als Kegellager 18 ausgebildet, wobei entweder dessen Konus-Innenring 18a oder dessen Konus-Außenring 18b und / oder dessen Kegelrollen 18c jeweils die Isolierkörper 5 bilden.According to a third embodiment (FIGS. 3 and 3A), the insulating body 5 is designed as a tapered bearing 18, with either its inner cone ring 18a or its outer cone ring 18b and / or its tapered rollers 18c each forming the insulating bodies 5.
Aufgrund einer vierten Ausführungsform (Fig. 4) ist der Konus-Innenring 18a axial verschiebbar und unter Federkraft auf der Rollenwelle 4 anstellbar. Der Konus-Innenring 18a ist auf der Rollenwelle 4 axial mittels Tellerfedern 19, die gegen einen Wellenabsatz 20 abgestützt sind, gegen den hohlen, mit dem Rol- lenmantel 1 fest verbundenen Konus-Außenring 18b verschiebbar. Das Drehmoment wird bei dieser Gestaltung durch Reibschluss im Konus- Außenring 18b übertragen. Das Isoliermaterial bildet der konische Außenring 18b aus Keramik. Anstelle von Keramik können auch Glasfasertextilien bei entsprechender Dicke oder Schichtung eingesetzt werden.Based on a fourth embodiment (FIG. 4), the inner cone ring 18a is axially displaceable and can be adjusted on the roller shaft 4 under spring force. The inner cone ring 18a is axially displaceable on the roller shaft 4 by means of disc springs 19, which are supported against a shaft shoulder 20, against the hollow outer cone ring 18b, which is firmly connected to the roller shell 1. The torque is transmitted in this configuration by frictional engagement in the cone outer ring 18b. The insulating material is formed by the conical outer ring 18b made of ceramic. Instead of ceramic, glass fiber textiles can also be used with the appropriate thickness or layering.
Ein Rollenmantel-Abschnitt 1 a, 1 b usw. kann jeweils an den Rollenenden 2 und / oder 3 in dem Kegellager 18 und etwa mittig mittels der über den Umfang verteilten Isolierkörper 5 gelagert werden.A roller jacket section 1 a, 1 b etc. can be mounted on the roller ends 2 and / or 3 in the tapered bearing 18 and approximately in the middle by means of the insulating bodies 5 distributed over the circumference.
Zur Verhinderung von Kriechströmen über die Oberfläche der Isolierkörper 5 ist eine trockene Umgebungsatmosphäre anzustreben. Eine solche besteht z.B. in dem Bereich eines Behandlungsofens. BezugszeichenlisteIn order to prevent leakage currents over the surface of the insulating bodies 5, a dry ambient atmosphere is desirable. One such example is in the area of a treatment furnace.
