Description
Die Lagerung des schwenkbaren Oberbaues voll Kranen, Baggern, Albsetzern, schwenkbaren Förderern usw. erfolgt in Schwenkwerken, die unterhalb ! der Oberbauplattform angebracht sind. Im allgemeinen liegen die Kugeln der Lagerung unterhalb eines Oberhauringträgers, so daß der Druck des Oberbaues praktisch unmittelbar auf die Mittellinie des Kugellaufringes einwirkt. Die Kontrolle der in den Laufring eingelegten Kugeln ist schwierig, da die Kugeln schwer zugänglich sind. :Außerdem ist meist noch dein Kugellaufring außen der Schwenkzahnkranz seitlich vorgelagert. Die schwere Zugänglichkeit ist nachteilig für die Kontrolle und für die Erneuerung von Teilen des', Kugellaufringes.The storage of the swiveling superstructure full of cranes, excavators, Albsetzern, swiveling conveyors etc. takes place in swiveling mechanisms that are below! the superstructure platform are attached. In general, the bearing balls are located below an upper ring carrier, so that the pressure of the superstructure is practically directly on the center line of the ball race acts. The control of the balls inserted in the race ring is difficult because the balls are difficult to access. : In addition, your ball race ring is usually still on the outside the slewing ring gear laterally in front. Difficult access is a disadvantage for checking and renewing parts of the 'ball race.
Die Erfindung erstrebt, die Nachteile der be- kannten Bauform zu beseitigen. Sie betrifft ein Schwenkwerk und besteht darin, daß der Oberbaue ringträger an einer oder mehreren, vorzugsweise ,in zwei minderbelasteten Stellen aus der ':Mitte des Kugelringes herausgelegt ist. Der Oberbauringträger kann dabei um einen bestimmten Abstand eingezogen oder auch nach außen verlegt sein. Zweckmäßig wird der Oberbauringträger an seinen weniger belasteten Stellen von der Kugelringinitte verlegt. Beim Stützwerk gemäß der Ertindung kommt damit die Stützkonstruktion an einigen Stellen nicht mehr auf die Mitte des j Kugelringes zu liegen, so daß an diesen Stellen die darunterliegenden Kugeln zugänglich sind. Bei einer einfachen Ausführungsform kann die Kugellaufbähn an diesen Stellen durch eine vorzugsweise in einett Führungsschlitz einstellbare, genebenenfalls mehrfach geteilte :11bdeckplatte alr izedeckt sein. nehmen und die das Herausnehmen der Kugeln aus dem Beobachtungsschlitz erleichtern.The invention seeks to eliminate the disadvantages of the known design. It relates to a swivel mechanism and consists in the fact that the superstructure ring carrier is laid out at one or more, preferably in two less stressed points from the ': center of the ball ring. The superstructure ring carrier can be drawn in by a certain distance or moved outwards. The upper ring carrier is expediently relocated from the center of the ball ring at its less stressed points. In the case of the support structure according to the invention, the support structure no longer comes to rest on the center of the ball ring at some points, so that the balls below are accessible at these points. In a simple embodiment, the ball track can be covered at these points by a cover plate which is preferably adjustable in a guide slot and which is also divided into several parts. and which make it easier to remove the balls from the observation slot.
In der Zeichnung ist eine Ausführungsform der Erfindung schematisch dargestellt. und zwar zeigt .A,bb. i eine Aufsicht und Ahb. 2 einen Schnitt entlang der Fläche a-a.An embodiment of the invention is shown schematically in the drawing shown. namely shows .A, bb. i a supervision and ahb. 2 shows a section along the area a-a.
Der Oberbauringträger i liegt unmittelbar über den Kugeln 2, von denen jeweils sechs, auch mehr oder weniger, in einem Kugelkäfig 3 zusammengehalten sind. An den Stellen 4 und 5 ist der Oberlrauringträger i nach innen zurückgezogen, so daß an diesen Stellen die Kugeln des Laufringes frei liegen. :1n diesen Stellen sind, wie Aibb. 2 zeigt, die Kugeln durch ein Abdeckblech 6 abgedeckt, das durch die Halteschrauben 7 gehalten wird. Das A:bdeckblech wird in einem Führungsschlitz 8 eingeschoben. An dem Abdeckblech 6 ist außerdem das Kugelführungsstück 9 befestigt, das sich zur Sicherung gegen einen etwaigen Kugeldruck und zur Entlastung des Abdeckbleches 6 Reit einer Eindrehung io gegen einen am Oberbau angesetzten Stegring 11 abstützt. Nach hem Abnehmen des Abdeckbleches 6 samt dem Führungsstück9 sind die Kugeln sichtbar und können samt ihren Käfigen 3 herausgenommen werden. Das Abdeckblech kann auch in mehrere Teile aufgeteilt sein.The Oberbaurringträger i is directly above the balls 2, of which six, also more or less, are held together in a ball cage 3. At points 4 and 5, the Oberlrauringträger i is withdrawn inwards, see above that the balls of the race are exposed at these points. : 1 in these places are like Aibb. 2 shows the balls covered by a cover plate 6, which is through the retaining screws 7 is held. The cover plate is in a guide slot 8 inserted. The ball guide piece 9 is also attached to the cover plate 6, that is to secure against any ball pressure and to relieve the cover plate 6 riding a recess io is supported against a web ring 11 attached to the superstructure. After removing the cover plate 6 together with the guide piece 9, the balls are visible and can be removed together with their cages 3. The cover plate can also be divided into several parts.
An dem Oberlbau ist außen der Schwenkzahnkranz 12 :befestigt, so daß die Kugeln seitlich nur schwer zugänglich sind. Mit 13 ist der Stützring des Unterbaues bezeichnet. Zur Sicherung der Kugelführung kann ein vorzugsweise mit der A'bdeckplatte verbundenes Kugelführungsstück angeordnet sein. Damit bei einem etwa auftretenden seitlichen Kugeldruck dieser von dem Führungsstück ohne weitere Beanspruchung anderer Bauteile, wie insbesondere der Aladeckplatte, aufgefangen wird, kann das Führungsstück vorzugsweise mit einem etwa in flöhe der Kugeln angeordneten Ansatz sich gegen ein am Oberbau angeordnetes Bauteil, wie Steigring, abstützen.The swivel ring gear 12: is attached to the outside of the superstructure so that the balls are difficult to access from the side. At 13 is the support ring of the substructure designated. To secure the ball guide, a cover plate connected ball guide piece be arranged. So with a possibly occurring lateral ball pressure of this from the guide piece without further stress on others Components, such as the aluminum cover in particular, can be caught by the guide piece preferably with an approach arranged approximately at the level of the balls against one another Support the component arranged on the superstructure, such as the riser ring.
Bei dem erfindungsgemäßen Schwenkwerk wird gleichsam ein Sehschlitz bzw. Beobachtungsschlitz geschaffen, durch den die darunterliegende Kugella,ufringbalin heim Schwenken des Oberbaues in allen Teilen beobachtet werden kann. So wird eine leichte. einfache und übersichtliche Kontrolle der Kugeln, ihrer Beschaffenheit und der Kugelbahn geschaffen.In the case of the pivot mechanism according to the invention, a viewing slit becomes, as it were, a viewing slit or observation slot created through which the underlying Kugella, ufringbalin The pivoting of the superstructure can be observed in all parts. So becomes a easy. simple and clear control of the balls and their properties and the marble run created.
Zur Erleichterung des Herausnehmens der Kitgeln können ver'hältnismäßi.g kleine Kugelkäfige vorgesehen sein, die nur wenige Kugeln auf-To make it easier to take out the kitgel small ball cages with only a few balls
