Abstract

The invention relates to a propeller shaft made of aluminium tubing with a balancing body of steel sheet secured on the circumference of the propeller shaft. The balancing body formed from a sheet-metal blank has at least one hole. The balancing body, having been placed, is secured by means of an aluminium retention plug applied by fusion welding through the hole, such that the retention plug fills the hole and overlaps the outside of the balancing body in the manner of a rivet head.

Description

GelenkwellePTO shaft

Die Erfindung betrifft eine Gelenkwelle nach dem Oberbegriff des Anspruchs 1.The invention relates to a cardan shaft according to the preamble of the claim 1.

Das Auswuchten von aus Stahlrohr bestehenden Gelenkwellen ist bekannt und wird durch Aufschweißen von Wuchtkörpern aus Stahl vorgenommen, die entsprechend der Unwucht an der betreffenden Stelle am Wellenumfang mittels Schweißung verbunden werden.The balancing of cardan shafts made of steel tube is known and is made by welding on balancing bodies made of steel, which accordingly the imbalance is connected by welding at the relevant point on the shaft circumference will.

Es ist z. B. eine Gelenkwelle bekannt (DE-OS 28 51 293), bei der das Wellrohr aus einem nicht metallenen Werkstoff besteht, welches mit seinen Enden auf einen hohlen Stahlzapfen des Kardangelenkes aufgeschraubt ist, wobei der Stahlzapfen axial gegenüber dem Wellrohr übersteht.It is Z. B. a cardan shaft known (DE-OS 28 51 293), in which the Corrugated pipe made of a non-metallic material, which with its ends is screwed onto a hollow steel pin of the universal joint, the steel pin axially protrudes from the corrugated pipe.

Das Auswuchten erfolgt bekanntermaßen dadurch, daß auf den büchsenähnlichen Stahlzapfen ein Ausgleichsgewicht aus Stahl durch elektrische Widerstandsschweißung aufgepunktet wird.The balancing is known to take place in that on the sleeve-like Stahlzapfen a balance weight made of steel by means of electrical resistance welding is scored.

Es ist eine andere Gelenkwelle aus Aluminiumrohr bekannt (DE-PS 31 04 068.3), bei welcher im axialen Bereich der Wuchtstelle eine Manschette aus dünnmandigem Stahlblech aufgebracht ist und wobei auf dieser Manschette Wuchtgewichte aus Stahl durch elektrische Widerstandsschweißung aufgepunktet sind. Da die Manschette mit Preßsitz auf der Welle verdreh- und verschiebefest haftet, muß in diesem Bereich die Welle vorher kalibriert werden - ein zusätzlicher Arbeitsgang, welcher mit Kosten verbunden ist.Another cardan shaft made of aluminum pipe is known (DE-PS 31 04 068.3), in which in the axial area of the balancing point a sleeve made of thin-stranded Sheet steel is applied and with balancing weights made of steel on this sleeve by electrical resistance welding are dotted. Since the The sleeve with a press fit on the shaft is not twisted or shifted, must be in the shaft must be calibrated beforehand in this area - an additional work step, which is associated with costs.

Das Aufpunkten von Aluminiumblechen als Wuchtkörper ist auf aus Aluminiumrohr bestehenden Gelenkwellen nicht möglich, weil Wuchtbleche aus Aluminium wegen des geringen spezifischen Gewichtes einerseits relativ groß in den Abmessungen gewählt werden müßten und andererseits wegen der Oxidschicht an der Oberfläche der Aluminiumrohrwelle und des dadurch bedingten hohen elektrischen Widerstandes, das übliche Punkt-Verschweißen nur mit hoher Stromstärke und hoher Anpreßkraft durchführbar ist, so daß an diesen Stellen Querschnittsverformungen an der Gelenkwelle nicht auszuschließen sind. Außerdem sind Wuchtbleche mit großen Abmessungen radial platzaufwendig und lassen sich nicht auf den engen Bereich der Wuchtstelle lokalisieren. Radial abstehende Wuchtkörper erzeugen jedoch bei hohen Drehzahlen der Welle unerwünschte Geräusche.The puncturing of aluminum sheets as balancing bodies is made of aluminum tubing existing cardan shafts not possible because balancing plates made of aluminum because of the Low specific weight on the one hand chosen to be relatively large in size would have to be and on the other hand because of the oxide layer on the surface of the aluminum tube shaft and the resulting high electrical resistance, the usual spot welding can only be carried out with high amperage and high contact pressure, so that at these If cross-sectional deformations on the cardan shaft cannot be ruled out. aside from that are balancing plates with large dimensions radially space-consuming and can not localize in the narrow area of the balancing point. Radially protruding balancing bodies however, generate undesirable noises at high shaft speeds.

Aufgabe der Erfindung ist es, bei aus Aluminium bestehenden Gelenkwellen eine einfache und sichere Befestigung von spezifisch schweren Wuchtkörpern zu ermöglichen, die klein gehalten werden können und daher geräuscharm und innerhalb enger Grenzen lokalisierbar sind.The object of the invention is, in the case of cardan shafts made of aluminum to enable a simple and safe attachment of specifically heavy balancing bodies, which can be kept small and therefore quiet and within narrow limits are localizable.

Diese Aufgabe wird durch die kennzeichnenden Merkmale des Anspruchs t gelöst. Durch die angeschweißten nietkopfartigen Haltezapfen aus Aluminium wird das gekrümmte, dem Außendurchmesser der Welle angepaßte Wuchtblech aus Stahl zuverlässig gehalten. Als Schweißverfahren hierfür eignet sich insbesondere das MIG-Schweißverfahren.This task is achieved by the characterizing features of the claim t resolved. The welded-on rivet-head-like retaining pins made of aluminum the curved one Balancing plate adapted to the outer diameter of the shaft reliably held from steel. A particularly suitable welding process for this is the MIG welding process.

In vorteilhafter Ausgestaltung der Erfindung kann die Bohrung im Schwerpunkt des Blechzuschnittes angebracht sein. Dadurch kann das Wuchtblech mittels einer einzigen Verschweißung zuverlässig gehalten werden.In an advantageous embodiment of the invention, the hole in the center of gravity of the sheet metal blank. This allows the balancing plate by means of a single weld can be held reliably.

Schließlich können -wenn das Wuchtblech größer sein muß - mehrere auf der durch den Schwerpunkt des Blechzuschnittes verlaufenden Mantellinie des gewölbten Blechzuschnittes liegende Bohrungen und entsprechende Haltezapfen vorgesehen werden. Größere Wuchtbleche werden zweckmäßigerweise axial länger gestaltet damit die Umfangsabmessung klein gehalten und das Wuchtgewicht umfangsmäßig in engen Grenzen lokalisiert werden kann.Finally - if the balancing plate has to be larger - several on the surface line of the running through the center of gravity of the sheet metal blank Arched sheet metal blank lying holes and corresponding retaining pins provided will. Larger balancing plates are expediently designed to be axially longer the circumferential dimension kept small and the balancing weight circumferentially within narrow limits can be localized.

Anhand eines in der Zeichnung dargestellten Ausführungsbeispieles soll die Erfindung näher erläutert werden.Based on an embodiment shown in the drawing the invention is to be explained in more detail.

Die Fig. zeigt einen Teil-Schnitt durch eine Gelenkwelle mit aufgebrachtem Wuchtblech gemäß der Erfindung.The figure shows a partial section through a cardan shaft with an applied Balancing plate according to the invention.

Der dargestellte Ausschnitt -aus einer aus Aluminium bestehenden Rohrwelle 1 weist an der Wuchtstelle 2 gewölbte, dem Außenumfang der Rohrwelle 1 angepaßte, aus Stahlblech gebildete Wuchtkörper 3 auf, die Jeweils mittels eines durch eine Bohrung 4 des aufgelegten Wuchtkörpers 3 hindurch mit Schmelzschweißung aufgetragenen Haltezapfens 5 an der Rohrwelle 1 gehalten werden. Der Haltezapfen 5 füllt die Bohrung 4 ganz aus und übergreift diese an der Wuchtkörperaußenzeite 6 nietkopfartig.The section shown - from a tubular shaft made of aluminum 1 has arched at the balancing point 2, adapted to the outer circumference of the tubular shaft 1, made of sheet steel on balancing bodies 3, each by means of a Bore 4 of the applied balancing body 3 applied therethrough with fusion welding Retaining pin 5 are held on the tubular shaft 1. The retaining pin 5 fills the bore 4 completely and overlaps it at the balancing body outer side 6 like a rivet head.

Die Bohrung 4 kann auch an der Wuchtkörperaußenseite 6 eine Ansenkung 7 aufweisen.The bore 4 can also have a countersink on the balancing body outer side 6 7 have.
