Abstract
Das erfindungsgemäße Axial-Schrägnadellager (9, 10) zeichnet sich dadurch aus, dass die eine Laufscheibe (10) an einem inneren und die andere Laufscheibe (11) an einem äußeren Ende je einen einander entgegengerichteten Kragen (10.1, 11.1) aufweisen, wobei die Kragen (10.1, 11.1) einen Käfig (4) oder die Lagernadeln (5) formschlüssig hintergreifen, so dass eine unverlierbare Baueinheit gebildet ist und dass wenigstens eine der Laufscheiben (10, 11) im Anschluss an die Laufbahn einen verlängerten Bereich (10.2, 11.2) aufweist, der in seiner Ausdehnung den Kragen (11.1, 10.2) der anderen Laufscheibe (11, 10) überdeckt, so dass ein Raum zur Aufnahme eines elastischen Dichtelementes (12) gebildet ist.The axial angular contact needle bearing (9, 10) according to the invention is characterized in that the one running disk (10) at an inner end and the other running disk (11) at an outer end each have a mutually opposing collar (10.1, 11.1) Collar (10.1, 11.1) engage behind a cage (4) or the bearing needles (5) in a form-fitting manner, so that a captive structural unit is formed and that at least one of the running disks (10, 11) has an extended area (10.2, 11.2 ), which covers the collar (11.1, 10.2) of the other running disk (11, 10) in its extent, so that a space for receiving an elastic sealing element (12) is formed.
Description
Anwendungsgebiet der Erfindungfield of use the invention
Die Erfindung betrifft ein Axial-Schrägnadellager, deren Lagernadeln Drehachsen aufweisen, die unter einem Winkel geneigt zu einer Lagerachse auf zugehörigen Laufbahnen zwischen zwei planparallelen, insbesondere aus Blech gebildeten Laufscheiben abwälzen.The The invention relates to an axial helical needle bearing whose bearing needles Having axes of rotation which are inclined at an angle to a bearing axis on associated Runways between two plane-parallel, in particular of sheet metal roll off the formed discs.
Hintergrund der Erfindungbackground the invention
Derartig gattungsgemäß ausgebildete Axial-Schrägnadellager sind bereits bekannt.Such Generically trained Axial angular contact needle roller bearings are already known.

Zusammenfassung der ErfindungSummary the invention
Ausgehend von den Nachteilen des bekannten Standes der Technik liegt der Erfindung daher die Aufgabe zugrunde, ein gattungsgemäßes Axial-Schrägnadellager so zu gestalten, dass es beim Transport nicht in seine Einzelbestandteile zerfallen kann. Eine weitere Aufgabe der Erfindung ist die Bereitstellung einer entsprechenden Abdichtung des Lagers.outgoing from the disadvantages of the known prior art is the invention therefore the object of a generic axial needle roller bearing so that it is not in its individual components during transport can fall apart. Another object of the invention is the provision a corresponding sealing of the bearing.
Erfindungsgemäß wird diese Aufgabe nach dem kennzeichnenden Teil von Anspruch 1 in Verbindung mit dessen Oberbegriff dadurch gelöst, dass die eine Laufscheibe an einem inneren und die andere Laufscheibe an einem äußeren Ende je einen einander entgegengerichteten Kragen aufweisen, wobei die Kragen einen Käfig oder die Lagernadeln formschlüssig hintergreifen, so dass eine unverlierbare Baueinheit gebildet ist und dass wenigstens eine der Laufscheiben im Anschluss an die Laufbahn einen verlängerten Bereich aufweist, der in seiner Ausdehnung den Kragen der anderen Laufscheibe überdeckt, so dass ein Raum zur Aufnahme eines elastischen Dichtelements gebildet ist.According to the invention this Task according to the characterizing part of claim 1 in conjunction solved with the preamble in that the one running disk on one inner and the other running disk on an outer end each having a mutually opposing collar, wherein the Collar a cage or the bearing needles form-fitting engage behind, so that a captive assembly is formed and that at least one of the pulleys following the raceway an extended one Has area in its extension the collar of the other Covered disc, so that a space is formed for receiving an elastic sealing element is.
Durch die erfindungsgemäße Ausgestaltung der beiden Laufscheiben, die den Käfig oder die Lagernadeln stirnseitig umgreifen, wird das Lager axial zusammengehalten. Es ist also nicht mehr möglich, dass beim Transport die eine Laufscheibe von der anderen Laufscheibe in axialer Richtung abgleiten kann. Insgesamt ist somit das ganze Handling der Axial-Schrägnadellageranordnung vereinfacht. Das elastische Dichtelement ist eine sehr kostengünstige Lösung und sorgt insbesondere dafür, dass die Anschlusskonstruktion vereinfacht wer den kann, weil eben die Abdichtung bereits immanenter Bestandteil der Lageranordnung ist. Darüber hinaus ist es möglich, über Querschnitt und Material des elastischen Dichtelements eine gewünschte Dichtungsvorspannung einzustellen.By the embodiment of the invention both running wheels holding the cage or embrace the end of the bearing needles, the bearing is held together axially. It is no longer possible that during transport one running disk from the other running disk can slide off in the axial direction. Overall, therefore, the whole Handling of the axial helical needle bearing assembly simplified. The elastic sealing element is a very cost effective solution and ensures in particular that the connecting structure simplifies who can, because just the seal already immanent part of the bearing assembly is. About that In addition, it is possible over cross section and material of the elastic sealing member a desired sealing bias adjust.
Die Erfindung wird an nachstehenden Ausführungsbeispielen näher erläutert.The Invention will be explained in more detail in the following embodiments.

Die vorstehend beschriebenen, erfindungsgemäß ausgebildeten Axial-Schrägnadellager lassen sich mit Hilfe der Spanlostechnologie in unterschiedlichen Größenverhältnissen kostengünstig als unverlierbare Baueinheit herstellen, verkörpern neben der ausgezeichneten Abdichtung hohe Tragzahlen bei hoher Steifigkeit und geringem Gewicht. Aufgrund ihrer harten Laufbahnen ist es auch möglich, die Umgebungskonstruktion gegebenenfalls aus leichteren Werkstoffen, beispielsweise Aluminium, zu fertigen.The described above, inventively designed axial helical needle roller bearings can be used in different ways with the help of chip breaking technology proportions economical as a captive assembly, embody beside the excellent Sealing high load ratings with high rigidity and low weight. Because of their hard running tracks, it is also possible the surrounding construction optionally made of lighter materials, such as aluminum, to manufacture.
