Definitions
- the invention relates to a sliding block for spindles on drives of rolling mills, wherein the articulated spindle has a flat pin whose tongue engages in a transverse to the axis of rotation cylindrical opening of a spindle head, between which and the flat pin of the sliding block is arranged.
- Sliding elements or sliding blocks often called joint stones, are known in various designs.
- Bearing alloys containing copper are also from the EP 1 133 588 B1 known.
- the DE 26 56 257 A1 describes joint stones for joint spindles and joint coupling heads of rolling mill drives, which are composed of several sub-segments, which may be constructed of different materials such as steel, non-ferrous metal or plastic.
- the invention is therefore based on the object to provide a sliding block available, which allows both a high surface pressure, as well as a sufficient heat resistance, without the copper or copper alloys are free during abrasion.
- a sliding block for spindles on drives of rolling mills wherein the articulated spindle has a flat pin whose tongue engages in a transverse to the axis of rotation cylindrical opening of the spindle head, between which and the flat pin of the sliding block is arranged, characterized in that the Compound sliding block is formed, with a metallic inner body and an outer layer of polymer fiber material surrounding this.
- such a polymer fiber material in particular a carbon fiber material is very suitable to absorb the high surface pressures and heat loads that occur in the transmission of torques in mill drives.
- the sliding block according to the invention can be used both on the motor side and the roller side.
- this composite sliding block requires no additional lubrication, for example by fat, oil or oil mist. Due to the material properties of this composite sliding block can be dispensed with a cooling, at least it can be significantly reduced compared to conventional bearings.
- the sliding block may have an inner body made of steel and according to a further embodiment, the division of the sliding block into several segments is possible, which are of course also designed in composite construction.
- Hycomp ® As carbon fiber material Hycomp ® can be used for example.
- the joint spindle 1 has a flat pin 2, the tongue 3 engages in a transverse to the axis of rotation cylindrical opening of the spindle head 4.
- this consists of two semi-annular Gleitsteinsegmenten, which are interconnected by a sliding pin 8.
- the sliding block is made of a metallic, e.g. Steel, existing inner body 6 and a carbon fiber outer layer 7 is made.

Description
- Die Erfindung betrifft einen Gleitstein für Gelenkspindeln an Antrieben von Walzwerken, wobei die Gelenkspindel einen Flachzapfen aufweist, dessen Zunge in eine quer zur Drehachse liegende zylindrische Öffnung eines Spindelkopfes eingreift, zwischen dem und dem Flachzapfen der Gleitstein angeordnet ist.
- Gleitelemente oder Gleitsteine, oft auch Gelenksteine genannt, sind in verschiedenen Ausbildungen bekannt.
- So sind in der
WO 99/36210 A1 - Lagerlegierungen, die Kupfer enthalten, sind auch aus der
EP 1 133 588 B1 bekannt. - Weiterhin ist ein Gleitlager bekannt aus der
US 5 422 150 A , wobei hier die Beschichtung aus einer Polymerverbindung besteht. - Die
DE 26 56 257 A1 beschreibt Gelenksteine für Gelenkspindeln und Gelenkkupplungsköpfe von Walzwerksantrieben, die aus mehreren Teilsegmenten zusammengesetzt sind, wobei diese aus unterschiedlichen Materialien wie Stahl, Nichteisenmetall oder Kunststoff aufgebaut sein können. - Schließlich sei noch die
DE 36 23 721 A1 erwähnt, die Gelenkspindeln mit geschmierten Gelenksteinen offenbart. - Derartige Kupfer enthaltende Legierungen zeichnen sich zwar durch sehr gute Gleit- bzw. Schmiereigenschaften aus, haben aber den Nachteil, dass beim Abrieb Kupfer frei wird. Für bestimmte Walzverfahren, insbesondere aber spezielle Walzprodukte, ist es nicht zulässig, dass dieser Kupferabrieb in den Walzprozess gelangt.
- Im Gegensatz zu derartigen Lagerbuchsen oder Lagerschalen, die drehende Teile aufnehmen, erfolgt bei Gleitsteinen, die Übertragung von Drehmomenten, also eine völlig andere Art der Belastung.
- Versuche, zur Übertragung von Drehmomenten Gleitsteine aus Kunststoff einzusetzen, sind bisher gescheitert, weil diese Materialien keine ausreichende Flächenpressung bzw. Warmfestigkeit aufweisen.
- Der Erfindung liegt daher die Aufgabe zugrunde, einen Gleitstein zur Verfügung zu stellen, der sowohl eine hohe Flächenpressung zulässt, wie auch eine ausreichende Warmfestigkeit besitzt, ohne dass beim Abrieb Kupfer oder Kupferlegierungen frei werden.
- Gelöst wird diese Aufgabe erfindungsgemäß bei einem Gleitstein für Gelenkspindeln an Antrieben von Walzwerken, wobei die Gelenkspindel einen Flachzapfen aufweist, dessen Zunge in eine quer zur Drehachse liegende zylindrische Öffnung des Spindelkopfes eingreift, zwischen dem und dem Flachzapfen der Gleitstein angeordnet ist, dadurch, dass der Gleitstein in Verbundbauweise ausgebildet ist, mit einem metallischen Innenkörper und einer diesen ummantelnden Außenschicht aus Polymerfasermaterial.
- Überraschenderweise hat sich gezeigt, dass ein derartiges Polymerfasermaterial, insbesondere ein Kohlefasermaterial sehr geeignet ist, die hohen Flächenpressungen und Wärmebelastungen, die bei der Übertragung von Drehmomenten in Walzwerksantrieben auftreten, aufzunehmen.
- Der erfindungsgemäße Gleitstein kann sowohl auf der Motorenseite wie auch der Walzenseite eingesetzt werden.
- Von besonderem Vorteil ist, dass es keiner zusätzlichen Schmierung, beispielsweise durch Fett, Öl oder Ölnebel bedarf. Aufgrund der Materialeigenschaften dieses Verbundgleitsteines kann auf eine Kühlung verzichtet werden, zumindest kann sie gegenüber herkömmlichen Lagern wesentlich eingeschränkt werden.
- Der Gleitstein kann einen Innenkörper aus Stahl aufweisen und nach einer weiteren Ausgestaltung ist auch die Aufteilung des Gleitsteines in mehrere Segmente möglich, die dann natürlich ebenfalls in der Verbundbauweise ausgestaltet sind.
- Als Kohlefasermaterial kann beispielsweise Hycomp ® verwendet werden.
- Die Erfindung soll nachfolgend an einem Ausführungsbeispiel erläutert werden, wobei in den
Figuren 1 und 2 schematisch der Lageraufbau und die Ausbildung des Gleitsteines dargestellt sind. - Die Gelenkspindel 1 weist einen Flachzapfen 2 auf, dessen Zunge 3 in eine quer zur Drehachse liegende zylindrische Öffnung des Spindelkopfes 4 eingreift.
- Zwischen dem Flachzapfen 2 und dem umgebenden Spindelkopf 4 ist der Gleitstein 5 angeordnet. Bei dem in der
Figur 1 dargestellten Ausführungsbeispiel besteht dieser aus zwei halbringförmigen Gleitsteinsegmenten, die durch einen Gleitbolzen 8 miteinander verbunden sind. - Die Verbundbauweise des Gleitsteines ergibt sich aus der schematischen Darstellung des geschnittenen Gleitsteines in
Figur 2 . - Hier ist ersichtlich, dass der Gleitstein aus einem metallischen, z.B. Stahl, bestehenden Innenkörper 6 und einer Kohlefaser- Außenschicht 7 besteht.
