Beschreibungdescription
Die Erfindung betrifft eine Tragrolle für Rollgänge oder Förderbänder bestehend aus einem Rohrkörper mit zylindrischem Mantel, an dessen Enden stirnseitig koaxiale Achsschenkel zur Aufnahme von Traglagern angeordnet sind, in denen die Tragrolle drehbar abgestützt ist.The invention relates to a support roller for roller tables or conveyor belts consisting of a tubular body with a cylindrical jacket, at the ends of which are arranged coaxial steering knuckles for receiving support bearings, in which the support roller is rotatably supported.
Tragrollen dienen dem Transport von Gütern. Sie werden in Rollgängen undCarrier rollers are used to transport goods. They are in roller tables and
Förderbandanlagen eingesetzt. Abhängig von dem Gewicht und/oder der Auflagelänge des zu fördernden Gutes bestimmt sich der Abstand der einzelnen Tragrollen. Dadurch ergibt es sich, daß bei längeren Transportwegen häufig eine große Anzahl gleichartiger Tragrollen notwendig ist. Zum Transport von Stückgütern sind mindestens einzelne dieser Tragrollen mit einem Antrieb zu versehen, hierbei sind sowohl Einzelantriebe als auch Gruppenantriebe bekannt. Einzelantriebe werden bei Rollgängen für hohes Stückgewicht verwendet; sonst werden Gruppenantriebe mit Verzahnung oder Triebstock verwendet. Bei Förderungen mit Gefälle kann auch ganz auf einen Antrieb verzichtet werden. Auch für Förderbänder aus elastischem Material, insbesondere zum Transport von Schüttgütern, werden Tragrollen eingesetzt.Conveyor belt systems used. Depending on the weight and / or the support length of the goods to be conveyed, the distance between the individual idlers is determined. As a result, a large number of identical support rollers is often necessary for longer transport routes. For the transport of piece goods, at least some of these idlers are to be provided with a drive, both individual drives and group drives are known. Single drives are used on roller tables for high piece weights; otherwise group drives with toothing or drive rack are used. A drive can also be dispensed with entirely for slopes with a gradient. Carrier rollers are also used for conveyor belts made of elastic material, in particular for transporting bulk goods.
Die bekannten Tragrollen bestehen aus einem Rohrkörper mit zylindrischem Mantel, der aus einem nahtlosen oder geschweißten Rohr oder auch aus Schleuderguß hergestellt ist. An den Enden dieses Rohrkörpers sind aus einem Rundmaterial gebildete Achsschenkel angebracht, die üblicherweise mittels Stegen oder demThe known idlers consist of a tubular body with a cylindrical jacket, which is made of a seamless or welded tube or from centrifugal casting. At the ends of this tubular body are formed from a round material stub axle, which is usually by means of webs or the
Innenumfang des Rohrkörpers angepaßter Scheiben befestigt sind, wobei letztere in die Rohrenden eingesetzt sind und den jeweiligen Achsschenkel konzentrisch zum Rohr aufnehmen. Der Aufbau der bekannten Tragrollen erfordert eine Vielzahl von Arbeitsschritten wie Vordrehen, Schweißen und Nachbearbeiten. Dabei ist ausreichende Präzision erforderlich, um den Rundlauf der Tragrolle im Rollgang bzw. im Förderband zu gewährleisten. Insgesamt ergibt sich im Vergleich zum Materialwert ein sehr hoher Bearbeitungspreis, der die bekannten Tragrollen sehr teuer macht. Berücksichtigt man, daß in Rollgängen oder bei Förderbändern eine Vielzahl dieser gleichartigen Tragrollen zum Einsatz kommen, so ergibt sich in Summe ein sehr hoher Kostenaufwand, der die Gesamtanlage verteuert.Fitted disks are attached to the inner circumference of the tube body, the latter being inserted into the tube ends and receiving the respective steering knuckle concentrically with the tube. The construction of the known idlers requires a variety of steps such as pre-turning, welding and finishing. Sufficient precision is required to ensure the concentricity of the idler roller in the roller table or to ensure in the conveyor belt. Overall, compared to the material value, there is a very high processing price, which makes the known idlers very expensive. If one takes into account that a large number of these identical support rollers are used in roller tables or in conveyor belts, the overall result is a very high cost which makes the entire system more expensive.
Aufgabe der vorliegenden Erfindung ist es, eine Tragrolle zum Einsatz in Rollgängen oder Förderbändern zu schaffen, die durch Einsparung von Bearbeitungsschritten wesentlich preisgünstiger als bisher herzustellen ist und mit dem Rollgänge und Förderbänder wirtschaftlich bestückt werden können.The object of the present invention is to provide a support roller for use in roller tables or conveyor belts, which can be manufactured much more economically than previously by saving processing steps and which can be economically equipped with roller tables and conveyor belts.
Zur Lösung der Aufgabe wird vorgeschlagen, daß die Achsschenkel zur Aufnahme der Traglager durch Verjüngen der beiden Enden des Rohrkörpers aus diesem geformt sind.To achieve the object, it is proposed that the steering knuckles for receiving the support bearing be formed by tapering the two ends of the tubular body therefrom.
Bei der neuartigen Gestaltung der Tragrollen wird idealerweise von einem Rohrstück als Grundkörper ausgegangen, das beispielsweise in einem Kaltziehvorgang hergestellt ist. Die Enden dieses Rohrstückes werden in ihrem Durchmesser so verjüngt, daß sie einen unmittelbar an den Rohrkörper angeformten Lagersitz für die Traglager bilden.The new design of the idlers ideally starts with a piece of pipe as the base body, which is produced, for example, in a cold drawing process. The ends of this pipe section are tapered in their diameter so that they form a bearing seat for the support bearings which is directly molded onto the pipe body.
Der Verformungsvorgang kann in Ausgestaltungen der Erfindung sowohl im warmen als auch im kalten Zustand erfolgen. Vorteilhafterweise kommt es dabei zu einer Materialanhäufung im Bereich der Lagerstelle, die erfindungsgemäß durch Reduzieren der Enden des Rohrkörpers mittels Drückwalzen oder durch Schmieden im Gesenk erzeugt wird. An dieser reduzierten Stelle kann durch spanende Bearbeitung in erfindungsgemäßer Weise der Sitz für das Traglager, beispielsweise durch Drehen, erzeugt werden, ebenso läßt sich im Bereich der Materialanhäufung in dem verjüngten Rohrendbereich ein Anschluß für den Antrieb einer angetriebenen Tragrolle herstellen.In embodiments of the invention, the deformation process can take place both in the warm and in the cold state. This advantageously results in an accumulation of material in the region of the bearing point, which is produced according to the invention by reducing the ends of the tubular body by means of pressure rolls or by forging in the die. At this reduced point, the seat for the support bearing, for example by turning, can be produced by machining in the manner according to the invention, and a connection for driving a driven support roller can also be made in the area of material accumulation in the tapered tube end region.
Um sicherzustellen, daß sich der Mantel des Rohrkörpers konzentrisch zur Lagerung dreht, sollte die Herstellung des Lagersitzes beim spanenden Bearbeiten der verformten Enden des Rohrkörpers mittels Aufnahme des Rollenkörpers in Lünetten erfolgen; auf diese Weise lassen sich die Anforderungen an die Laufrundheit der Tragrolle leicht erfüllen. Die vorgeschlagene Tragrolle ist in ihrer Herstellung durch Einsparung von Bearbeitungsschritten wesentlich preiswerter als die bekannten aus mehreren Teilen zusammengesetzten Tragrollen. Durch Verwendung von präzisem Vormaterial läßt sich eine wesentliche Kosteneinsparung bei gleicher Beanspruchbarkeit der Rolle erreichen. Zusätzlich läßt sich durch die Verwendung von weniger Material eine Gewichtseinsparung erzielen; der verwendete Rohrkörper bietet darüber hinaus Vorteile bei der Walzenkühlung beim Transport von warmem Material. Die relativ einfache Fertigung durch drehende Bearbeitung zur Verformung der Rohrenden dient der Vermeidung von Fehlern beim herkömmlichen aufwendigen Fertigungsprinzip.In order to ensure that the jacket of the tubular body rotates concentrically to the bearing, the bearing seat should be produced during machining of the deformed ends of the tubular body by receiving the roller body in steadies; In this way, the requirements for the roundness of the idler roller can be easily met. The proposed idler roller is significantly cheaper to manufacture than the known idler rollers composed of several parts in terms of its manufacturing steps. By using precise raw material, a significant cost saving can be achieved with the same strength of the roll. In addition, weight savings can be achieved by using less material; the tubular body used also offers advantages for roller cooling when transporting warm material. The relatively simple production by rotating machining to deform the pipe ends serves to avoid errors in the conventional complex production principle.
Ein Ausführungsbeispiel der erfindungsgemäßen Tragrolle ist in der Zeichnung dargestellt und wird nachfolgend beschrieben.An embodiment of the support roller according to the invention is shown in the drawing and is described below.
Die erfindungsgemäße Tragrolle ist im Längsschnitt in der linken Darstellungshälfte gezeigt. In der rechten Hälfte der Darstellung ist eine konventionelle Tragrollenausbildung dargestellt, die nachfolgend der Erfindung gegenübergestellt wird. Mit 2 ist die Wand eines Rohrkörpers 1 bezeichnet, die den Mantel der Tragrolle bildet. Wie in der rechten Zeichnungshälfte erkennbar, ist in den Innenumfang des Rohrkörpers 1 ein Achsschenkel 4 eingesetzt, der seinerseits in ringförmigen ScheibenThe support roller according to the invention is shown in longitudinal section in the left half of the illustration. In the right half of the illustration, a conventional idler design is shown, which is compared with the invention below. With 2 the wall of a tubular body 1 is designated, which forms the jacket of the support roller. As can be seen in the right half of the drawing, a steering knuckle 4 is inserted into the inner circumference of the tubular body 1, which in turn is in annular disks
5 aufgenommen wird, die so dimensioniert sind, daß ihr Außenumfang dem Innenumfang des Rohrkörpers entspricht. Alle Teile sind nach Bearbeitung der miteinander korrespondierenden Oberflächen in das Rohr eingesetzt und beispielsweise durch Schweißen fixiert. Insbesondere zwischen dem Achsschenkel 4 und dem Rohr 2 muß ein exakter Rundlauf um die gemeinsame zentrale Achse 6 gewährleistet sein, damit der Lauf der Tragrolle nicht gestört wird.5 is added, which are dimensioned so that their outer circumference corresponds to the inner circumference of the tubular body. After processing the corresponding surfaces, all parts are inserted into the pipe and fixed, for example, by welding. In particular, between the steering knuckle 4 and the tube 2, an exact concentricity around the common central axis 6 must be ensured so that the running of the idler roller is not disturbed.
In der linken Zeichnungshälfte ist die erfindungsgemäße Lösung dargestellt, die augenfällig die Tragrolle wesentlich vereinfacht. Das Ende 2a des Rohrkörpers 1 ist in der dargestellten Weise verjüngt, d.h. Rohrinnen- und -außendurchmesser sind mit einem konischen Übergang zum Rohrende hin zu einem Zapfen verkleinert, der den Achsschenkel für die Tragrolle bildet. Dieser Achsschenkel läßt sich beispielsweise durch Warmformen im Gesenk oder mittels Drückwalzen herstellen, wobei es zu einer Wandverdickung im Bereich 7 kommt. Im Bereich dieser Wandverdickung wird durch spanende Bearbeitung ein Lagersitz 8 erzeugt, auf den das Traglager aufgeschoben wird. Durch Einspannen der Tragrolle während der Fertigung des Lagersitzes 8 in Lünetten wird ein exakter Rundlauf sowohl des Rohrkörpers 1 als auch des Lagers gewährleistet. In the left half of the drawing, the solution according to the invention is shown, which obviously considerably simplifies the idler. The end 2a of the tube body 1 is tapered in the manner shown, ie the tube inside and outside diameters are reduced with a conical transition to the tube end towards a pin which forms the steering knuckle for the support roller. This steering knuckle can be produced, for example, by hot forming in the die or by means of spinning rolls, with wall thickening in area 7. In the area of this wall thickening, a bearing seat 8 is produced by machining, onto which the support bearing is pushed becomes. By clamping the support roller during the manufacture of the bearing seat 8 in steadies, an exact concentricity of both the tubular body 1 and the bearing is ensured.
