Description
Die Erfindung betrifft eine Lagerungsanordnung für Kreuzgelenke, bei der die Zapfen eines Gelenkkreuzes in Augen der geteilten Wellengabeln durch Wälzkörper gelagert sind, die je einen äußeren Laufring (Laufbuchse) aufweisen, der in ein Gabelauge eingesetzt ist und sich axial durch einen Bund gegen die Gabel abstützt, in dem äußeren Laufring die Wälzkörper angeordnet sind, die entweder unmittelbar oder unter Zwischenschaltung eines inneren Laufringes am Kreuzzapfen abrollen, und zur Aufnahme von Axialkräften der äußere Laufring bzw. die Laufbüchse am Kreuzzapfen abgestützt ist.The invention relates to a mounting arrangement for universal joints in which the pins of a universal joint in the eyes of the split shaft forks are supported by rolling elements, each of which has an outer race (liner) have, which is inserted into a fork eye and is axially supported by a collar against the fork, in the outer race, the rolling elements are arranged, either directly or with the interposition of an inner race on the cross pin, and the outer race to absorb axial forces or the liner is supported on the cross pin.
Bei bekannten Kreuzgelenken (z. B. DT-Gbm 18 58 494), bei denen zur Aufnahme der A^ialkräfte zwischen dem Kreuzzapfen und dem Bund des äußeren Laufringes ein Axialwälzlager angeordnet ist, ist von. Nachteil, daß bei ungenauer Fertigung in der Montage nicht immer das exakte Spiel des Axiallagers und die genaue Fixierung des Zapfenkreuzes erreicht wird. In den Fällen, in denen kein optimales Spiel erreicht wird, sind Distanzscheiben zwischen Gelenkgabel und dem Bund des äußeren Laufringes notwendig.In known universal joints (e.g. DT-Gbm 18 58 494), in which to absorb the axial forces a thrust roller bearing is arranged between the cross pin and the collar of the outer race is from. Disadvantage that in the case of inaccurate manufacture in the assembly not always the exact play of the axial bearing and the exact fixation of the cross member is achieved. In those cases where optimal play is not achieved, spacers are required between the joint fork and the collar of the outer race.
Darüber hinaus ist als entscheidender Nachteil anzusehen, daß während des Betriebes der Gelenkwelle durch Abrieb und Verschleiß der einzelnen sich relativ gegeneinander bewegenden Teile das Spiel sich vergrößert und dadurch die Funktion des Gelenkes sich verschlechtert, so daß es ohne weiteres zur Zerstörung einzlener Teile oder sogar zum Ausfall der Gelenkwelle kommen kann.In addition, it is to be regarded as a decisive disadvantage that during operation of the cardan shaft due to abrasion and wear and tear of the individual parts moving relative to one another, the game itself enlarged and thereby the function of the joint deteriorates, so that it can easily be destroyed individual parts or even failure of the PTO shaft.
Des weiteren sind Kreuzgelenke bekannt (z. B. GB-PS 10 27 648), die jedoch für geringere Beanspruchung ausgelegt sind und bei denen die Axialkräfte durch den Laufbüchsenboden und nicht durch ein Axiallager aufgnommen werden. Die Zentrierung der Laufbuchse erfolgt durch einen Ring, welcher mit Gewinde versehen ist. Durch diese Maßnahmen wird der Außendurchmesser der Gelenkwelle derart vergrößert, daß viel Platz für die Lagerung verloren geht und die ganze Lagerungsanordnung auf einen unzulässig kleinen Arbeitshalbmesser verkleinert wird. Die Sicherung dieses Ringes erfolgt entweder durch Verstemmen bzw. Ausfüllen der Gewinderillen mit Kunststoff oder ähnlich oder durch Verspannung. Der entscheidende Nachteil besteht darin, daß ein Nachstellen, wenn überhaupt, ohne Zerstörung des Sicherungsmittels nicht möglich ist.Universal joints are also known (e.g. GB-PS 10 27 648), but they are designed for less stress are designed and where the axial forces through the liner base and not through a Axial bearings are included. The liner is centered by means of a ring, which with Thread is provided. These measures increase the outer diameter of the cardan shaft in such a way that that a lot of space for storage is lost and the entire storage arrangement is inadmissible on one small working radius is reduced. This ring is secured either by caulking or filling of the thread grooves with plastic or similar or by bracing. The decisive one The disadvantage is that readjustment, if at all, is not possible without destroying the securing means is possible.
Bei einer anderen Kreuzgelenkwelle (z. B. DT-AS (2 83 037) sind zur Fixierung der Lagerbuchse Sprengringe vorgesehen; diese sind jedoch für hohe Belastungen und bei schweren Kreuzgelenken ungeeignet. Die hohen Axialkräfte können von diesen Sprengringen nicht aufgenommen werden.On another universal joint shaft (e.g. DT-AS (2 83 037), snap rings are used to fix the bearing bush intended; however, these are unsuitable for high loads and heavy universal joints. the These snap rings cannot absorb high axial forces.
Hiervon ausgehend ist es Aufgabe der Erfindung, ein Kreuzgelenk zu schaffen, bei der eine einfache Lagerein- bzw. Lagernachstellung und eine genaue Zentrierung des Zapfenkreuzes in der Gelenkgabel bei gleichbleibendem Außendurchmesser des Gelenkes gewährleistet ist.Proceeding from this, it is the object of the invention to create a universal joint in which a simple Bearing adjustment or adjustment and a precise centering of the journal cross in the joint fork constant outer diameter of the joint is guaranteed.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß der die Wälzkörper aufnehmende äußere Laufring bzw. die Laufbuchse auf ihrer dem Körper des Kreuzes zugewandten äußeren Mantelfläche mit Gewinde versehen ist, auf der ein Stützring so aufgeschraubt ist, daß er sich an der Innenseite der zugehörigen Gabel abstützt, und daß der Stützring über eine Sicherungseinrichtung gegenüber der Gabel fixiert ist.The object is achieved according to the invention in that the outer race receiving the rolling elements or the bushing on its outer circumferential surface facing the body of the cross with a thread is provided on which a support ring is screwed so that it is on the inside of the associated fork supported, and that the support ring is fixed by a securing device relative to the fork.
Vorteilhaft bei dieser Ausbildung ist, daß nach dem Einsetzen des äußeren Laufringes bzw. der Laufbüchse das Zapfenkreuz ohne besonderen Montageaufwand sehr genau zentriert werden kann. Die Einstellung des gewünschten Spiels zwischen Axiallager und Laufring ist problemlos und stufenlos durchführbar ohne großen unwirtschaftlichen Meßaufwand.The advantage of this design is that after the insertion of the outer race or the liner the cross pin can be centered very precisely without any special assembly effort. The setting of the The desired play between the axial bearing and the raceway can be carried out smoothly and continuously without major uneconomical measurement effort.
Besonders ist bei dieser Ausführung von Vorteil, daß während des Betriebes eingetretenes Spiel durch Verschleiß, Abtrieb oder ähnlich ohne Demontage des Zapfenkreuzes bzw. der Gelenkgabel durch Nachstellen des Stützringes behoben werden kann.The particular advantage of this design is that play that has occurred during operation occurs Wear, output or similar without dismantling the journal cross or the joint fork by readjusting the support ring can be corrected.
