Abstract
Description
Die Erfindung betrifft eine Wälzlagerung für einen Kegelbrecher, bei dem auf einem Fußteil ein senkrecht angeordnetes Antriebsteil drehbar gelagert ist, an dessen oberem Ende ein Brecherkegel zur Senkrechten geneigt und frei rotierbar gelagert ist.The invention relates to a roller bearing for a cone crusher, in which a vertically arranged drive part is rotatably mounted on a foot part, at the upper end of which a crusher cone is inclined to the vertical and is freely rotatable.
Solche Lagerungen sind in vielen Varianten bekannt geworden. Die DE-OS 34 01 722 zeigt eine solche Wälzlagerung, bei der in einem Fußteil mittels eines Wälzlagers eine senkrechte, durch einen Motor angetriebene Welle gelagert ist. An ihrem oberen Ende trägt diese Welle ein zu dem ersten Wälzlager geneigt und exzentrisch versetzt angeordnetes zweites Wälzlager, welches andererseits den Brecherkegel abstützt. Da diese Wälzlagerungen nach außen hin ungeschützt sind, mußten bei dieser bekannten Ausführung aufwendige Dichtungsmaßnahmen angewandt werden, um die Lager gegen den im Betrieb anfallenden Staub ausreichend zu schützen.Such bearings have become known in many variants. DE-OS 34 01 722 shows such a roller bearing, in which a vertical shaft driven by a motor is mounted in a foot part by means of a roller bearing. At its upper end, this shaft carries a second roller bearing, which is inclined and eccentrically offset to the first roller bearing and which, on the other hand, supports the crusher cone. Since these roller bearings are unprotected to the outside, complex sealing measures had to be used in this known embodiment in order to adequately protect the bearings against the dust accumulating during operation.
Der Erfindung liegt die Aufgabe zugrunde, eine gegenüber dem bekannten Stand der Technik kompaktere, damit einfachere und billigere Lagerung für einen Kegelbrecher zu schaffen, die zudem wesentlich geringere Abdichtungsprobleme aufweist, als die bekannten Lagerungen.The invention has for its object to provide a more compact, thus easier and cheaper storage for a cone crusher compared to the known prior art, which also has much lower sealing problems than the known bearings.
Diese Aufgabe löst die Erfindung dadurch, daß die Wälzlagerung ausschließlich aus einem gemeinsamen hohlzylindrischen Außenteil, in welchem sich über Wälzkörper zwei axial hintereinanderliegende Innenringe abstützen, besteht, wobei das Außenteil Teil des Antriebsteiles ist, und der erste Innenring mit dem Fußteil verbunden ist, während der zweite, der zum ersten geneigt und exzentrisch versetzt ist, den Brecherkegel trägt. Dadurch, daß der gemeinsame Außenring den die Wälzkörper enthaltenden Innenraum überdeckt, ist nur noch zwischen dem oberen Ende des Außenlaufringes und dem Brecherkegel ein abzudichtender Spalt vorhanden, der in bekannter Weise durch Labyrinthdichtungen abgedichtet sein kann. Dagegen befindet sich der Lagerspalt am unteren Ende in dem Bereich des Fußteiles, in dem sich auch die Antriebsmittel befinden. Dieser Raum ist von dem Teil des Kegelbrechers, in welchem Staub anfällt, getrennt.The invention achieves this object in that the roller bearing consists exclusively of a common hollow cylindrical outer part, in which two inner rings lying axially one behind the other are located over roller bodies support, there is, the outer part is part of the drive part, and the first inner ring is connected to the foot part, while the second, which is inclined and eccentrically offset to the first, carries the crusher cone. Characterized in that the common outer ring covers the interior containing the rolling elements, there is only a gap to be sealed between the upper end of the outer race and the crusher cone, which gap can be sealed in a known manner by labyrinth seals. In contrast, the bearing gap is located at the lower end in the area of the foot part in which the drive means are also located. This space is separated from the part of the cone crusher in which dust is generated.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung im Längsschnitt dargestellt.In the drawing, an embodiment of the invention is shown in longitudinal section.
Auf das Fußteil 1 des Kegelbrechers ist ein erster Innenring 2 eines Wälzlagers aufgeschraubt, zwischen dem und dem Außenring 3 des Wälzlagers Zylinderrollen 4 abrollen, die in bekannter Weise als Kreuzrollen angeordnet sind, das heißt, daß die Achsen aufeinanderfolgender Zylinderrollen in bekannter Weise unter einem Winkel von 90° zueinander stehen.On the
An das untere Ende des Außenringes 3 ist ein Zahnkranz 5 angeschraubt, in dessen Verzahnung das Kegelritzel 6 eingreift, welches auf der z. B. in nicht dargestellter Weise durch einen Elektromotor angetriebenen Antriebswelle 7 befestigt ist.At the lower end of the outer ring 3, a ring gear 5 is screwed, in whose teeth the
Der Außenring 3 zusammen mit dem Zahnkranz 5 bilden das Antriebsteil 8 des Kegelbrechers.The outer ring 3 together with the ring gear 5 form the drive part 8 of the cone crusher.
Im oberen Bereich des Außenringes 3 ist ein zweiter Kranz von Zylinderrollen 4 angebracht, die in einem zweiten Innenring 9 abrollen, welcher gegenüber dem ersten Innenring 2 geneigt und exzentrisch versetzt ist. Auf diesem zweiten Innenring 9 ist der Brecherkegel 10 aufgeschraubt.In the upper area of the outer ring 3 there is a second ring of cylindrical rollers 4 which roll in a second inner ring 9 which is inclined and offset eccentrically with respect to the first
An der Funktion des Brecherkegels hat sich gegenüber bekannten Ausführungen durch die erfindungsgemäße Wälzlagerung nichts verändert. Es wurde lediglich die Lagerung selbst vereinfacht und es wurden insbesondere die bei herkömmlichen Lagerungen beträchtlichen Abdichtprobleme beseitigt.The function of the crusher cone has not changed compared to known designs by the roller bearing according to the invention. Only the storage itself was simplified and, in particular, the sealing problems which were considerable with conventional bearings were eliminated.
Es versteht sich, daß die Erfindung nicht auf eine Wälzlagerung beschränkt ist, bei der als Wälzkörper Kreuzrollen verwendet werden. Es ist vielmehr jegliche bekannte Wälzlagerung einsetzbar, die in der Lage ist, Radial- und Axialkräfte, sowie auftretende Kippmomente aufzunehmen.It is understood that the invention is not limited to a roller bearing in which crossed rollers are used as the rolling elements. Rather, any known roller bearing can be used, which is able to absorb radial and axial forces, as well as occurring tilting moments.
