Description

Axialsicherung für eine Nadellagerbuchse Axial lock for a needle bearing bush

Die Erfindung betrifft eine Axialsicherung für eine Nadellagerbuchse zur Aufnahme eines Zapfenkreuzes im Gabelauge eines Gabelschenkels einer Gelenkgabel, wobei das Gabelauge einen Paßsitzbereich zur Aufnahme der Lagerbuchse und einen sich nach außen an den Paßsitzbereich anschließenden erweiterten Durchmesserbereich aufweist, und die Nadellagerbuchse gegen axiale Verschiebung nach außen durch, mittels Kaltfließpressen angestauchte, radial nach innen in das Gabelauge weisende Nasen gesichert ist.The invention relates to an axial lock for a needle bearing bush for receiving a cross member in the fork eye of a fork leg of a joint fork, wherein the fork eye has a snug fit area for receiving the bearing bush and a enlarged diameter area adjoining the snug fit area to the outside has, and the needle bearing bush against axial displacement outward by means of Cold extrusion upset noses pointing radially inward into the fork eye is secured.

Es ist eine Axialsicherung gemäß dem Oberbegriff zur Halterung von Nadellagerbuchsen in den Gabelaugen einer Gelenkgabel bekannt (DE-GM 1 907 637). Bei der beschriebenen Ausführung werden am äußeren Rand des Gabelauges Nasen durch Kaltfließpressen gegen die Stirnfläche der Nadellagerbuchse gepreßt. Diese Axialsicherung weist den großen Nachteil auf, daß, falls das Gelenkkreuz mit den Nadellagerbüchsen wegen Verschleißes ersetzt werden muß, die angepreßten Nasen nur durch spanabhebende Werkzeuge zu beseitigen sind.It is an axial lock according to the preamble for holding Needle bearing bushes in the fork eyes of a joint fork known (DE-GM 1 907 637). In the described execution on the outer edge of the fork eye Lugs pressed against the face of the needle bearing bush by cold extrusion. This axial locking has the major disadvantage that, if the joint cross with the needle bearing bushes must be replaced due to wear, the pressed-on lugs can only be removed with cutting tools.

Zum anschließenden Befestigen des neu einzusetzenden Gelenkkreuzes lassen sich zwar mit einem hierfür ausgebildeten Preßstempel neue Nasen anpreßen, jedoch läßt sich dieses Verfahren nicht beliebig oft wiederholen.For the subsequent attachment of the new universal joint to be inserted it is true that new noses can be pressed on with a press ram designed for this purpose, however, this process cannot be repeated indefinitely.

Der Erfindung liegt die Aufgabe zugrunde eine einfache Möglichkeit zur Axialsicherung von Nadellagerbuchsen zu schaffen, die es ermöglicht in gewissen Grenzen Bauteiltoleranzen auszugleichen, und bei deren Einsatz das Gelenkkreuz mit den Nadellagerbuchsen beliebig oft ausgetauscht werden kann.The invention is based on the object of a simple possibility to create axial securing of needle bearing bushings, which makes it possible in certain Compensate for limits component tolerances, and when using the universal joint the needle bearing bushes can be replaced as often as required.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß a) die Nadellagerbuchse in den erweiterten Durchmesserbereich des Gabelauges reicht, b) die Nadellagerbuchse nach außen gegen eine innere Ringzone eines Sicherungsringes abgestützt ist, c) der Außendurchmesser des Sicherungsringes dem erweiterten Durchmesserbereich des Gabelauges entsprechend ausgebildet ist, d) der Sicherungsring nach außen innerhalb einer aus dem vergrößerten Durchmesserbereich und dem Paßsitzbereich gebildeten Ringzone gegen die angepreßten Nasen abgestützt ist.According to the invention, this object is achieved in that a) the needle bearing bush extends into the enlarged diameter range of the fork eye, b) the needle bearing bushing is supported to the outside against an inner ring zone of a locking ring, c) the outer diameter of the locking ring corresponds to the extended diameter range of the Fork eye is designed accordingly, d) the locking ring to the outside inside one formed from the enlarged diameter area and the snug fit area Ring zone is supported against the pressed noses.

Von besonderem Vorteil bei der erfindungsgemäßen Ausbildung einer Axialsicherung ist, daß da die durch Kaltfließpressen gebildeten Nasen nicht in den Paßsitzbereich für die Nadellagerbuchse hineinreichen, das Gelenkkreuz in herkömmlicher Weise durch Ausbau der Sicherungsringe mit einer hierzu vorgesehenen Zange demontiert werden kann. Irgendwelche spanabhebenden Arbeitsvorgänge sind hierzu nicht notwendig. Auch können die Sicherungsringe nach Einsetzen eines neuen Gelenkkreuzes mit den diesem zugeordneten Nagellagerbuchsen in herkömmlicherweise mit einer Spezialzange wieder eingesetzt werden. Durch die vorgeschlagene Ausbildung einer Axialsicherung können bei Bedarf Gelenkkreuze beliebig häufig gewechselt werden, da keine Veränderungen an den Nasen notwendig sind.Of particular advantage in the inventive formation of a Axial security is that the noses formed by cold extrusion are not in extend into the snug fit area for the needle bearing bushing, the universal joint in a conventional manner Way, dismantled by removing the retaining rings with pliers provided for this purpose can be. Any machining operations are not necessary for this. Also, after inserting a new joint cross with the this associated nail bearing bushes in a conventional manner with special pliers to be reinstated. Due to the proposed design of an axial lock Joints can be changed as often as required, as there are no changes on the noses are necessary.

Dieser Vorteil schlägt insbesondere zu Buche, wenn die beschriebene Axialsicherung in Gelenkwellen zum Antrieb von landwirtschaftlichen Maschinen durch die Zapfwelle eines Schleppers eingesetzt wird. Ein notwendiger Wechsel eines Gelenkkreuzes kann hier gegebenenfalls auf dem Feld vorgenommen werden.This advantage is particularly noticeable when the described Axial locking in cardan shafts for driving agricultural machines the PTO shaft of a tractor is used. A necessary change of a joint cross can be done here if necessary on the field.

Da sich zwischen der Anlage des Sicherungsringes am Boden der Nagellagerbuchsen und seiner Außenabstützung gegen die Nasen ein gewisser Hebelarm einstellt, werden die Nadellagerbuchsen federnd in Anlage an den Zapfen des Gelenkkreuzes gehalten.Since between the system of the locking ring on the bottom of the nail bearing bushes and its external support against the noses adjusts a certain lever arm the needle bearing bushes are resiliently held in contact with the journals of the universal joint.

Hierdurch ergibt sich eine spielfreie Lagerung für das Gelenkkreuz und die Möglichkeit Toleranzen in gewissen Grenzen auszugleichen.This results in a backlash-free mounting for the universal joint and the possibility of compensating for tolerances within certain limits.

Nachstehend wird die Erfindung anhand eines Ausführungsbeispieles näher erläutert.The invention is described below using an exemplary embodiment explained in more detail.
