- wherein the hollow shaft is rotatably supported about a shaft axis in at least one secondary bearing and one main bearing,
- the sub-bearing and the main bearing being axially distanced,
- the laying tube holder is connected to the hollow shaft in a rotationally fixed manner, projects beyond the main bearing and carries the laying tube,

Ein derartiger Windungsleger ist allgemein bekannt. Beispielhaft wird auf die EP 0 679 453 A1 verwiesen.Such a winding layer is generally known. Exemplary reference is made to EP 0 679 453 A1.
Im Betrieb rotiert der Windungsleger um die Wellenachse. Gleichzeitig wird dem Windungsleger entlang der Wellenachse das stabförmige Walzgut mit Walzgutgeschwindigkeit zugeführt. Das Walzgut läuft in das Einlaßende des Legerohres ein und tritt tangential aus dem Auslaßende aus, so daß es in Form einer Serie von Ringen bzw. Windungen auf einem Transportband abgelegt werden kann. Die Umfangsgeschwindigkeit des Auslaßendes, die proportional zur Drehzahl und zum radialen Abstand des Auslaßendes von der Wellenachse ist, entspricht etwa der Walzgutgeschwindigkeit. In operation, the winding layer rotates around the shaft axis. At the same time, the winding layer is along the shaft axis the rod-shaped rolling stock is fed at the rolling stock speed. The rolling stock runs into the inlet end of the laying tube and emerges tangentially from the outlet end so that it is in shape a series of rings or turns on a conveyor belt can be filed. The peripheral speed of the outlet end, which are proportional to the speed and radial distance the outlet end of the shaft axis corresponds approximately the rolling stock speed.
Der Windungsleger erfährt im Ruhezustand bei horizontal verlaufender Wellenachse eine schwerkraftbedingte Durchbiegung. Diese Durchbiegung bestimmt im wesentlichen die Resonanzfrequenz. Die Resonanzfrequenz begrenzt die Drehzahl und damit indirekt auch die maximal mögliche Walzgutgeschwindigkeit. Die Resonanzfrequenz ist um so höher, je geringer die schwerkraftbedingte Durchbiegung des Legerohrhalters im Ruhezustand ist.The winding layer experiences in the rest state with horizontally running A deflection due to gravity. This deflection essentially determines the resonance frequency. The resonance frequency limits the speed and thus indirectly also the maximum possible rolling stock speed. The lower the gravity-related, the higher the resonance frequency Deflection of the laying tube holder in the idle state is.
Die Aufgabe der vorliegenden Erfindung besteht darin, einen Windungsleger derart weiterzuentwickeln, daß er eine möglichst geringe schwerkraftbedingte Durchbiegung und damit eine möglichst große Resonanzfrequenz aufweist.The object of the present invention is a Winding layer to evolve in such a way that it is as possible low deflection due to gravity and thus a has the largest possible resonance frequency.
Die Aufgabe wird dadurch gelöst, daß der Legerohrhalter zumindest teilweise aus einem Material besteht, das eine geringere Dichte als Stahl aufweist.The object is achieved in that the laying tube holder at least partially made of a material that is less Has density than steel.
Als Materialien kommen insbesondere Leichtmetalle, z. B. Aluminium und Magnesium, oder Kunststoffe, insbesondere faserverstärkte Kunststoffe, in Frage.As materials come in particular light metals, e.g. B. aluminum and magnesium, or plastics, especially fiber-reinforced Plastics, in question.
Der Legerohrhalter weist üblicherweise ein Anschlußstück zum drehfesten Verbinden mit der Hohlwelle, ein im wesentlichen rotationssymmetrisches Mittelstück, eine am Mittelstück angeordnete Tragstruktur für das Legerohr und eine Ausgleichsstruktur zum Ausgleichen von Unwuchten auf. Zumindest die Tragstruktur sollte aus dem Material bestehen, das eine geringere Dichte als Stahl aufweist.The laying tube holder usually has a connector for non-rotatable connection with the hollow shaft, a substantially rotationally symmetrical center piece, one arranged on the center piece Support structure for the laying pipe and a compensation structure to compensate for unbalance. At least that Support structure should consist of the material that is a lesser Has density than steel.
Durch die Verwendung von Leichtmetall oder faserverstärktem Kunststoff im Überhangbereich des Windungslegers, also jenseits des Hauptlagers, wird die schwerkraftbedingte Durchbiegung aber selbst dann deutlich verringert, wenn auch das noch biegebeanspruchte Mittelstück und evtl. sogar das Anschlußstück aus Leichtmetall gefertigt sind. Denn jenseits des Hauptlagers ist die Krümmung der Biegelinie relativ gering, so daß die schwerkraftbedingte Durchbiegung im wesentlichen von der Biegelinienneigung der Hohlwelle am Hauptlager bestimmt wird. Der niedrigere Elastizitätsmodul der tragenden Teile im Überhangbereich erhöht deshalb die schwerkraftbedingte Durchbiegung nur geringfügig.Through the use of light metal or fiber reinforced Plastic in the overhang area of the winding layer, i.e. beyond of the main bearing, the deflection caused by gravity but significantly reduced even if that too bend-stressed middle piece and possibly even the connecting piece are made of light metal. Because beyond Main bearing, the curvature of the bending line is relatively small, so that the gravity-induced deflection essentially determined by the bending line inclination of the hollow shaft at the main bearing becomes. The lower modulus of elasticity of the load-bearing Parts in the overhang area therefore increase the gravity-related Deflection only slight.
Auch das Legerohr kann aus einem Material bestehen, das eine geringere Dichte als Stahl aufweist. Gleiches gilt für einen dem Legerohr nachgeordneten Führungsfortsatz. Hier kommen aufgrund der thermischen Beanspruchung dieser Teile insbesondere keramische Werkstoffe, ggf. auch Verbundwerkstoffe aus Leichtmetall und Keramik, in Frage. Das Legerohr kann z. B. aus einem Leichtmetall bestehen und auf seiner Innenseite eine Keramikschicht aufweisen.The laying tube can also be made of a material that is one has lower density than steel. The same applies to one guide extension subordinate to the laying tube. Come here due to the thermal stress on these parts in particular ceramic materials, possibly also composite materials Light metal and ceramic, in question. The laying tube can e.g. B. consist of a light metal and one on the inside Have ceramic layer.

Walzgut 1 dem Windungsleger 2 mit einer Walzgutgeschwindigkeit
vW zugeführt. Gleichzeitig rotiert der Windungsleger 2
mit einer Drehzahl n um eine Wellenachse 5. Der Windungsleger
2 wird dabei in bekannter Weise mittels eines Motors 6 über
ein Getriebe 7, üblicherweise ein Umlenkgetriebe 7, angetrieben. According to Figure 1, a rod-shaped rolling stock 1 is by means of a
Gemäß Figur 2 weist der Windungsleger 2 eine Hohlwelle 8, einem

in einem Nebenlager 11 und einem Hauptlager 12 derart gelagert
ist, daß die Hohlwelle 8 um die Wellenachse 5 drehbar
ist. Das Nebenlager 11 und das Hauptlager 12 sind axial distanziert.According to FIG. 2, the

und ein im wesentlichen rotationssymmetrisches Mittelstück 14
auf. Mittels des Anschlußstücks 13 ist der Legerohrhalter 9
drehfest mit der Hohlwelle 8 verbunden. Mit dem Mittelstück
14 sind ein Tragblech 15, Stützbleche 16, 17 und eine Ausgleichsstruktur
18 verbunden.The laying tube holder 9 projects beyond the main bearing 12. He
has a
Das Tragblech 15 läuft mit dem Legerohr 10 um. Es weist Anschlußaugen
19 auf, an denen Halteelemente 20 befestigt sind.
Mittels der Halteelemente 20 trägt das Tragblech 15 und damit
auch der Legerohrhalter 9 das Legerohr 10. Die Stützbleche
16, 17 stützen das Tragblech 15 axial nach vorne und hinten
ab. Das Tragblech 15, die Stützbleche 16, 17 und die Halteelemente
20 bilden zusammen eine am Mittelstück 14 angeordnete
Tragstruktur für das Legerohr 10. Die Ausgleichsstruktur
18 dient zum Ausgleichen der von der Tragstruktur und dem Legerohr
10 verursachten Unwuchten.The
Das Legerohr 10 weist ein Einlaßende 21 und ein Auslaßende 22
auf. Zwischen dem Einlaßende 21 und dem Auslaßende 22 beschreibt
das Legerohr 10 eine dreidimensional gekrümmte Führungsbahn
für das Walzgut 1. Das Einlaßende 21 fluchtet mit
der Wellenachse 5. Das Auslaßende 22 hat von der Wellenachse
5 einen radialen Abstand d. Das Walzgut 1 läuft die Wellenachse
5 entlang, tritt am Einlaßende 21 in das Legerohr 10
ein und am Auslaßende 22 aus dem Legerohr 10 aus.The
Aufgrund der Drehzahl n und des Abstandes d läuft das Auslaßende
22 mit einer Umfangsgeschwindigkeit vU um die Wellenachse
5 um. Die Umfangsgeschwindigkeit vU korrespondiert mit der
Walzgutgeschwindigkeit vW. Das Auslaßende 22 beschreibt somit
einen Kreis 23 um die Wellenachse 5. Dem Legerohr 10 ist ein
Führungsfortsatz 24 nachgeordnet. Der Führungsfortsatz 24
dient insbesondere dem ordnungsgemäßen Ablegen der letzten

Im Ruhezustand weist der Windungsleger 2 bei horizontal verlaufender
Wellenachse 5 der Windungsleger 2 gemäß Figur 3 eine
schwerkraftbedingte Durchbiegung D auf. Die schwerkraftbedingte
Durchbiegung D ist dabei in Figur 3 der Deutlichkeit
halber stark übertrieben dargestellt. Die schwerkraftbedingte
Durchbiegung D bestimmt die Resonanzfrequenz, die der Windungsleger
2 im Betrieb aufweist. Die Resonanzfrequenz begrenzt
die Drehzahl n und damit indirekt auch die maximal
mögliche Walzgutgeschwindigkeit vW. Die Resonanzfrequenz ist
dabei um so höher, je geringer die schwerkraftbedingte Durchbiegung
D des Windungslegers 2 ist.In the idle state, the winding
Um die schwerkraftbedingte Durchbiegung D zu verringern und
so die Resonanzfrequenz und damit indirekt auch die maximal
mögliche Walzgutgeschwindigkeit vW zu erhöhen, besteht der
Windungsleger 2 nicht durchgängig aus Stahl. Insbesondere besteht
der Legerohrhalter 9 zumindest teilweise aus einem Material,
das eine geringere Dichte als Stahl aufweist. Als Materialien
kommen insbesondere Leichtmetalle, z. B. Aluminium
und Magnesium, in Frage. Ggf. kann auch ein faserverstärkter
Kunststoff verwendet werden. Dadurch kann erreicht werden,
daß die schwerkraftbedingte Durchbiegung D des Windungslegers
2 um mehr als die Hälfte gegenüber der schwerkraftbedingten
Durchbiegung D' eines konstruktiv identischen Windungslegers
aus Stahl reduziert wird.To reduce the deflection D caused by gravity and
so the resonance frequency and thus indirectly the maximum
to increase possible rolling stock speed
In erster Linie sollten zumindest die nicht biegebeanspruchten
Teile des Legerohrhalters 9 aus Leichtmetall gefertigt
werden. Zumindest die Tragstruktur sollte also aus Leichtmetall
bestehen. First and foremost, at least those that are not subjected to bending should

diesen Teilen kommen aufgrund der thermischen Beanspruchung

aus Leichtmetall und Keramik, in Frage. Das Legerohr
