Abstract
Description
Die Erfindung bezieht sich auf eine Drehdurchführung zur Zufuhr und/oder Abfuhr von strömendem Medium in einen axialen Hohlraum eines gelagerten drehbaren Maschinenbauteils, insbesondere bei Walzen und Rollen nach dem Oberbegriff des Anspruchs 1.The The invention relates to a rotary feedthrough for supply and / or discharge from pouring Medium in an axial cavity of a mounted rotary machine component, in particular for rollers and rollers according to the preamble of the claim 1.

Eine Drehdurchführung ohne drehbaren Teil ist aus der US-Patentschrift 1 718 209 bekannt. Ein gegossenes Anschlussgehäuse ist über einen Wellenkompensator mit einem scheibenförmigen Abdichtteil verbunden, das gegenüber dem drehbaren Maschinenbauteil abdichtet.A Rotary union without a rotatable part is known from US Pat. No. 1,718,209. A poured one connection housing is over a shaft compensator connected to a disc-shaped sealing member, the opposite the rotating machine component seals.
Bei
einer weiteren Drehdurchführung
nach dem Oberbegriff des Anspruches 1 (
Der Erfindung liegt die Aufgabe zugrunde, eine Drehdurchführung der oberbegrifflichen Art kostengünstiger herstellen zu können.Of the Invention is based on the object, a rotary feedthrough of generic kind cheaper to be able to produce.
Die gestellte Aufgabe wird aufgrund der Merkmale des Anspruches 1 gelöst und durch die weiteren Merkmale der abhängigen Ansprüche ausgestaltet und weiterentwickelt.The Asked object is achieved on the basis of the features of claim 1 and by the other characteristics of dependent claims designed and developed.
Im einzelnen umfasst der stationäre Teil der Drehdurchführung beide Mediumsanschlüsse, den Zufuhranschluss und den Abführanschluss. Der stationäre Teil ist an dem Lagerdeckel fest gehaltert, vorzugsweise angeschraubt. Die am stationären Teil angebrachten Mediumsanschlüsse können außerhalb des Lagerdeckels angeordnet werden, was bedeutet, dass in dem Lagerdeckel keine Zufuhr- und Abfuhrkanäle vorgesehen sein müssen.in the individual includes the stationary one Part of the rotary union both medium connections, the supply port and the discharge port. The stationary one Part is firmly held on the bearing cap, preferably screwed. The at the stationary Part mounted medium connections can outside the Bearing caps are arranged, which means that in the bearing cap no supply and discharge channels must be provided.
Von besonderer Bedeutung ist, dass der stationäre Teil einen im Wesentlichen rundsymmetrischen Innenraum umfassen kann, wobei ein Syphonrohr symmetrisch im Innenraum angeordnet ist und sich in Achsrichtung der Drehdurchführung erstreckt. Das Syphonrohr trennt den Vorlauf vom Rücklauf des strömenden Mediums innerhalb des axialen Hohlraumes des drehbaren Maschinenbauteils, das sich insbesondere als Walze oder Rolle darstellt. Diese weitgehend symmetrische Ausbildung des Innenraums des stationären Teils vermeidet Strömungsverengungen und sorgt für einen günstigen Strömungsverlauf.Of particular importance is that the stationary part may comprise a substantially circularly symmetrical interior, wherein a siphon tube is arranged symmetrically in the interior and extending in the axial direction of the rotary feedthrough. The siphon tube separates the flow from the return of the flowing medium within the axial cavity of the rotary machine component, which is in particular as a roller or roller. This largely symmetrical formation of the interior of the stationary part avoids Strömungsverengun and ensures a favorable flow.
Nach einer bevorzugten Ausgestaltung der Erfindung weist der stationäre Einsatzteil einen zylindrischen Anschlusskörper mit abgeflachten Anschlussseiten auf, die im Winkel zueinander angeordnet sind. Ein derartiger zylindrischer Anschlusskörper ist einfach zu fertigen. Der Winkel mit dem die Mediumsleitungen an dem Anschlusskörper angeschlossen sind, kann beispielsweise 90° betragen, was insbesondere dann in Betracht kommt, wenn der zylindrische Anschlusskörper mit vier Schrauben an dem Lagerdeckel befestigt wird.To a preferred embodiment of the invention, the stationary insert part a cylindrical connecting body with flattened connection sides, which are at an angle to each other are. Such a cylindrical connection body is easy to manufacture. The angle with which the medium lines are connected to the connection body can be, for example, 90 °, which in particular comes into consideration when the cylindrical connector body with four screws is attached to the bearing cap.
Zur Befestigung des Syphonrohres innerhalb des stationären Einsatzteils weist dieses eine axiale Aussparung auf, in welcher das Ende des Syphonrohres sitzt. Außerdem ist ein Zweiwege-Einsatz mit einem daran angebrachten Zapfen vorgesehen, der in die Innenwand des stationären Einsatzteils eingreift und an dem das Syphonrohr festgeschraubt ist. Der Zweiwege-Einsatz umfasst einen Rohrkörper mit Querbohrung, durch die das Syphonrohr verläuft. An der Durchdringungsstelle weist das Syphonrohr eine Queröffnung auf, die mit dem Inneren des Rohrkörpers des Zweiwege-Einsatzes in Verbindung steht, so dass auf diesem Wege eine Leitungsverbindung zwischen einem der Mediumsanschlüsse über das Innere des Zweiwege-Einsatzes ins Innere des Syphonrohres gegeben ist, während der andere Strömungsweg am Außenumfang des Syphonrohres durch den axialen Hohlraum des drehbaren Maschinenbauteils in den Innenraum des stationären Einsatzteils und von dort zu dem anderen Mediumsanschluss erfolgt. Es ergibt sich so ein relativ wenig behinderter Strömungsverlauf für das strömende Medium und wenig komplizierte Formen bei der Herstellung der Drehdurchführung.to Attachment of the siphon tube within the stationary insert this has an axial recess in which the end of Siphon pipe sits. Furthermore a two-way insert is provided with a pin attached thereto, in the inner wall of the stationary Engages insert and screwed to the siphon tube is. The two-way insert comprises a tubular body with transverse bore, through which runs the siphon pipe. At the point of penetration, the siphon pipe has a transverse opening, with the interior of the tubular body of the two-way use communicates, so that way a line connection between one of the medium connections via the interior given the two-way insert into the interior of the siphon tube, while the other flow path on the outer circumference the siphon tube through the axial cavity of the rotatable machine component in the interior of the stationary Insert part and from there to the other medium connection. This results in a relatively little impeded flow for the flowing Medium and less complicated shapes in the production of the rotary feedthrough.
