Abstract
Description
Die Erfindung betrifft eine Tragrolle, insbesondere für einen Gurtförderer.The The invention relates to a carrying roller, in particular for a Belt conveyor.
Die bekannten Tragrollen bestehen aus einem Rohrkörper mit zylindrischem Mantel, der aus einem nahtlosen oder geschweißten Rohr oder aus Schleuderguss hergestellt ist. An den axialen Enden des Rohrkörpers können für ein drehbares Lagern des Rohrkörpers Wälzlager eingesetzt sein. Der Aufbau der bekannten Tragrollen erfordert eine Vielzahl von Arbeitsschritten wie Vordrehen, Schweißen und Nachbearbeiten. Dabei ist eine ausreichende Präzision erforderlich um den Rundlauf der Tragrollen im Rollgang bzw. im Förderband zu gewährleisten. Weiterhin verfügen bekannte Tragrollen über ein beachtliches Gewicht, das bei Betrieb gedreht werden muss, wofür nicht unbeachtliche Energiemengen aufzuwenden sind.The known support rollers consist of a tubular body with a cylindrical shell, made of a seamless or welded pipe or centrifugal cast iron is made. At the axial ends of the tubular body can for a rotatable bearings of the tubular body roller bearing be used. The structure of the known support rollers requires a Variety of work steps such as pre-turning, welding and reworking. There is sufficient precision required for the concentricity of the idlers in the roller table or in conveyor belt to ensure. Continue to dispose known carrying roles over a considerable weight that has to be turned in operation, which is not incur inconsiderable amounts of energy.
Eine Aufgabe der Erfindung ist es daher, eine verbesserte Tragrolle zu schaffen.A The object of the invention is therefore to provide an improved carrying role create.
Die Aufgabe wird durch den Gegenstand des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen beschrieben.The The object is solved by the subject matter of claim 1. advantageous Embodiments are described in the subclaims.
Gemäß Anspruch 1 umfasst eine Tragrolle, insbesondere für einen Gurtförderer, folgende Merkmale:
- – Ein Hohlkörper mit einem Außenmantel entsprechend einem Kreiszylinder und
- – der Hohlkörper ist derart ausgebildet, dass ein Verhältnis des Außendurchmessers des Hohlkörpers zu einer Wandstärke wenigstens in einem axial mittleren Bereich des Hohlkörpers größer 41 ist.
- - A hollow body with an outer jacket corresponding to a circular cylinder and
- - The hollow body is formed such that a ratio of the outer diameter of the hollow body to a wall thickness at least in an axially central region of the hollow body is greater than 41.
Die Erfindung beruht dabei auf der Erkenntnis, dass bei einer Tragrolle das eigentliche Tragrollenrohr insbesondere durch ein Drückwalzen derartig kaltverfestigbar ist, dass es mit einem Verhältnis des Außendurchmessers zur Wandstärke größer 41 ausgebildet werden kann. Damit einhergehend werden die Vorteile erzielt, dass gegenüber bisherigen Lösungen bei gleicher Festigkeit eine geringere Wandstärke realisierbar ist. Damit ist das bei Betrieb der Tragrolle zu drehende Gewicht ein geringeres, womit sich bei Betrieb der Tragrolle eine entsprechende Energieeinsparung erzielen lässt.The The invention is based on the recognition that in a supporting role the actual support roller tube in particular by a spin forming is cold-workable such that it has a ratio of the outer diameter to the wall thickness larger 41 formed can be. Along with this, the advantages are achieved that across from previous solutions with the same strength a smaller wall thickness can be realized. In order to is the weight to be turned during operation of the carrying roller a smaller, bringing with it a corresponding energy saving during operation of the carrying roller achieve.
Weiterhin lässt sich insbesondere mittels besagtem Drückwalzen eine exakt kreiszylindrische Außengeometrie bei geringen Toleranzen und hohe Rundheit erzielen. Ein Überdrehen des Außenmantels und/oder Auswuchten zum Erzeugen einer vorgegebenen Präzision ist damit mit Vorteil nicht notwendig. Ferner ist es dadurch mit Vorteil auch möglich, von einem mit vergleichsweise geringer Qualität ausgebildeten und damit kostengünstigen Tragrollenrohrrohling auszugehen.Farther let yourself in particular by means of said pressure-rolling an exactly circular cylindrical outer geometry achieve low tolerances and high roundness. An overspeeding of the outer jacket and / or balancing to produce a given precision thus not necessary with advantage. Furthermore, it is thereby advantageous also possible, from a trained with comparatively low quality and therefore cost-effective Outgoing idle pipe blank.
