Description

Radial- und axial belastbares Wälzlager Radially and axially loadable rolling bearing
Beschreibungdescription
Die Erfindung bezieht sich auf ein radial und axial belastbares Wälzlager gemäß Oberbegriff des Patentanspruches 1.The invention relates to a radially and axially resilient bearing according to the preamble of claim 1.
Aus der DE 20 2005 007 904 Ul ist ein axial und radial belastbares Wälzlager, insbesondere Kegelrollenlager bekannt, das aus einem Außenring und einem Innenring und dazwischen angeordneten Wälzkörpern besteht, wobei zwei Kegelrollenlager spiegelbildlich zueinander mit ihrem Außenring in einer Nabe und mit ihrem Innenring auf einer Welle sitzen. Beide Lager sind dabei durch einen zwischen den Außenringen sitzenden Mittenbord voneinander beabstandet und werden zwischen zwei zusätzlichen Axialdrucklagern oder Spannringen mittels Schrauben axial verspannt. Die Dichtungen zur Abdichtung des Wälzlagers nach außen befinden sich hierbei in der Anschlusskonstruktion, so dass erst mit dem Anbau an die Anschlusskonstruktion das komplette, geschlossene Wälzlager entsteht.From DE 20 2005 007 904 Ul an axially and radially resilient roller bearing, in particular tapered roller bearing is known which consists of an outer ring and an inner ring and arranged therebetween rolling elements, wherein two tapered roller bearings mirror each other with its outer ring in a hub and with its inner ring on a Wave sit. Both bearings are spaced from each other by a seated between the outer rings center plate and are braced axially between two additional Axialdrucklagern or clamping rings by means of screws. The seals for sealing the rolling bearing to the outside are here in the adjacent construction, so that only with the attachment to the adjacent construction, the complete, closed roller bearing is formed.
Aus der DE 699 28 051 D2 ist ein zweireihiges Kegelrollenlager für eine Nabeneinheit für ein Kraftfahrzeug bekannt, wobei die Nabeneinheit einstückig als integralen Teil einen Flansch für das Befestigen am Fahrzeugrad und ein zylindrisches Teil enthält, das sich in einer axialen Richtung erstreckt und auf dessen Außenumfang teilweise direkt das Kegelrollenlager angeordnet ist. Der zweite Teil des Kegelrollenlagers wälzt sich auf einem zusätzlichen Lagerring ab, der nicht geschraubt, sondern geklemmt bzw. aufgeschrumpft wird. Auch hierbei wird der zusätzliche Gegenring mit Hilfe der Anschlusskonstruktion geklemmt. Es handelt sich dabei um ein aufwändiges Montageverfahren, wobei das Lager erst zusammen mit der Anschlusskonstruktion nach außen abgedichtet ist.From DE 699 28 051 D2 a double-row tapered roller bearing for a hub unit for a motor vehicle is known, wherein the hub unit integrally contains as integral part a flange for fastening to the vehicle wheel and a cylindrical part extending in an axial direction and on its outer periphery partially directly the tapered roller bearing is arranged. The second part of the tapered roller bearing rolls on an additional bearing ring, which is not screwed, but clamped or shrunk. Again, the additional counter ring is clamped with the help of the adjacent construction. It is a complex assembly process, whereby the bearing is only sealed to the outside together with the adjacent construction.
Der Erfindung liegt die Aufgabe zugrunde, ein Wälzlager vorzuschlagen, das als vorgefertigte Einheit ohne großen Aufwand an die Anschlusskonstruktion montiert werden kann. Die Lösung dieser Aufgabe ist im Patentanspruch 1 angegeben, wobei Wellendichtringe oder sonstige Dichtungselemente, die den Austritt des Schmiermittels aus dem Laufbahnsystem verhindern sollen, in die Lagerringe integriert sind und jeweils durch Klemmringe oder mit Hilfe sonstiger Konstruktionselemente in und/oder zwischen den Lagerringen fixiert sind. Hierdurch wird ein einbaufertiges Lager einschließlich eines integrierten Dichtsystems verwirklicht. Das erfindungsgemäße Kegelrollenlager ist insbesondere als ein selbsthaltendes Momentenlager ausgeführt, wobei Tragring und Haltering axial miteinander verschraubt sind und das Wälzlager insofern eine einbaufertige Einheit bildet. Dabei sind die Klemmringe bereits mit dem Nasenring und/oder den Tragringen und Halteringen, vorzugsweise mit Zylinderschrauben befestigt. Sie können aber auch durch eine sonstige durch die Kundenkonstruktion vorgegebene Einrichtung geklemmt werden. Das erfindungsgemäße Kegelrollenlager zeichnet sich zusätzlich dadurch aus, dass die Außenringe sowie die Innenringe mittels geeigneter Befestigungsschrauben mit der Anschlusskonstruktion verbunden werden können, wobei bereits entsprechende Durchgangsbohrungen oder Gewindebohrungen in den Ringen vorhanden sind. Das erforderliche Lagerspiel für das Wälzlager ist unabhängig von der Anschlusskonstruktion über den Stoß zwischen Tragring und Haltering in geeigneter Weise anpassbar. Zur genauen Positionierung und Ausrichtung an der Anschlusskonstruktion können am äußeren Umfang des Außenringes Zentrierflächen angeordnet sein, die gemeinsam mit den Laufbahnen der Wälzkörper bearbeitet werden können. Die Laufbahnen der Wälzkörper werden in an sich bekannter Weise mittels induktiver Härtung schlupflos hergestellt.The invention has for its object to propose a rolling bearing, which can be mounted as a prefabricated unit without much effort to the adjacent construction. The solution to this problem is specified in claim 1, wherein shaft seals or other sealing elements which are intended to prevent the escape of the lubricant from the raceway system, are integrated into the bearing rings and are fixed in each case by clamping rings or with the aid of other construction elements in and / or between the bearing rings , As a result, a ready-to-install bearing including an integrated sealing system is realized. The tapered roller bearing according to the invention is designed in particular as a self-retaining moment bearing, wherein the support ring and retaining ring are screwed together axially and the rolling bearing thus forms a ready to install unit. The clamping rings are already attached to the nose ring and / or the support rings and retaining rings, preferably with cylinder screws. However, they can also be clamped by another device specified by the customer construction. The tapered roller bearing according to the invention is additionally distinguished by the fact that the outer rings and the inner rings can be connected to the connecting structure by means of suitable fastening screws, wherein corresponding through bores or threaded bores are already present in the rings. The required bearing clearance for the rolling bearing is adapted independently of the adjacent construction on the joint between the support ring and retaining ring in a suitable manner. For accurate positioning and alignment with the adjacent construction centering surfaces can be arranged on the outer circumference of the outer ring, which can be processed together with the raceways of the rolling elements. The raceways of the rolling elements are manufactured without slipping in a conventional manner by means of inductive hardening.
