Abstract

An axial-radial ball bearing has an inner bearing ring (1; 5, 7) and two chamfered outer bearing rings (4) separated by the bearing balls (6). The outer bearing rings (4) are surrounded by a pre-tensioned bearing bush (2). A pliable seal is located between the bush and the two bearing outer rings (4). The three-point bearing is free of axial and radial play with all bearing balls subjected to equal load.

Description

Die Erfindung betrifft ein Axial-Radial-Kugellager entsprechend dem Oberbegriff des Patent­ anspruchs 1. Solche Lager sind in der Praxis bekannt.The invention relates to an axial-radial ball bearing according to the preamble of the patent claims 1. Such bearings are known in practice.

Solche Lager werden häufig für oszillierende Bewegungen eingesetzt, z. B. in Webmaschinen, wobei sich stets nur wenige Wälzkörper oder Lagerkugeln ständig in der Lastzone befinden. Nur diese wenigen Wälzkörper oder Lagerkugeln werden belastet, so daß hier eine große Gefahr der Brinellierung (Metallhärtung durch Druckkontakt) und/oder die Gefahr einer Tribokorrosion (Reibungskorrosion) besteht.Such bearings are often used for oscillating movements, e.g. B. in weaving machines, only a few rolling elements or bearing balls are always in the load zone. Only these few rolling elements or bearing balls are loaded, so that a large one Risk of brinellization (metal hardening due to pressure contact) and / or the risk of Tribocorrosion (frictional corrosion) exists.

Es ist eine Aufgabe der Erfindung, diese Nachteile zu beseitigen.It is an object of the invention to overcome these drawbacks.

Erfindungsgemäß wird ein Lager entsprechend dem Oberbegriff des Patentanspruchs 1 mit den in dessen kennzeichnendem Teil aufgeführten Merkmalen geschaffen.According to the invention, a bearing according to the preamble of claim 1 is included the characteristics listed in its characteristic part.

Da hiernach eine äußere Lagerhülse unter Vorspannung über nachgiebige Dichtungen auf die Lagerteile aufgeformt ist, entsteht ein sowohl axial als auch radial spielfreies Dreipunktlager. Jede Lagerkugel ist also an drei Punkten spielfrei abgestützt, nämlich an der Kugellaufbahn am Lagerinnenring und an den beiden Schrägflächen der beiden Lageraußenringe. Bei dieser Bauform können Fertigungstoleranzen durch das Aufformen der äußeren Lagerhülse über die anderen Lagerteile leicht ausgeglichen werden. Das Lager zentriert sich über die Kugel­ laufbahn am Lagerinnenring und über die an den beiden Außenringen angebrachten Schräg­ flächen selbst. Durch die nachgiebige Dichtung ist eine Sicherheit gegen eine zu hohe Vorspannung gegeben, die zu einem Blockieren der Lagerkugeln zwischen den Lagerlaufbah­ nen führen könnte. Die nachgiebige Dichtung wirkt hierbei als Ausgleichselement. Since then an outer bearing sleeve under prestress via flexible seals on the Bearing parts are molded on, a three-point bearing that is free of play both axially and radially is formed. Each bearing ball is supported without play at three points, namely on the ball raceway on the bearing inner ring and on the two inclined surfaces of the two bearing outer rings. At this Manufacturing tolerances can be achieved by molding the outer bearing sleeve over the other bearing parts can be easily compensated. The bearing is centered over the ball raceway on the bearing inner ring and over the slope attached to the two outer rings surfaces themselves. The resilient seal provides security against too high Given preload, which leads to a blocking of the bearing balls between the bearing race could lead. The resilient seal acts as a compensating element.  

Durch die auf diese Weise auf die Lagerkugeln ausgeübte leichte Vorspannung wird die Last über alle Lagerkugeln gleichmäßig vom Lagerinnenring auf die beiden Lageraußenringe übertragen. Dadurch sinkt die Belastung auf die einzelnen Lagerkugeln, und die Gefahr von Brinellierung oder Tribokorrosion wird vermindert.Due to the slight preload exerted on the bearing balls in this way, the load over all bearing balls evenly from the bearing inner ring to the two bearing outer rings transfer. This reduces the load on the individual bearing balls and the risk of Brineling or tribocorrosion is reduced.

Das erfindungsgemaße Kugellager läßt sich kostengünstig fertigen. Die nachgiebige Dichtung wirkt, insbesondere bei hohen oder kritischen Frequenzen, zusätzlich als Dämpfer (Schwin­ gungsdämpfung).The ball bearing according to the invention can be manufactured inexpensively. The compliant seal also acts as a damper (Schwin., especially at high or critical frequencies) damping).

Die Unteransprüche kennzeichnen vorteilhafte Weiterbildungen der Erfindung.The subclaims characterize advantageous developments of the invention.

Weitere Einzelheiten und Vorteile der Erfindung ergeben sich aus der folgenden Beschreibung von Ausführungsbeispielen anhand der Zeichnung.Further details and advantages of the invention will become apparent from the following description of exemplary embodiments with reference to the drawing.

Fig. 1 zeigt im Radialschnitt einen Teil einer ersten Ausführungsform; Fig. 1 shows in radial section part of a first embodiment;

Fig. 2 zeigt im Radialschnitt einen Teil einer zweiten Ausführungsform. Fig. 2 shows in radial section part of a second embodiment.

Gemäß Fig. 1 weist das Kugellager einen Lagerinnenring 1 aus gehärtetem Wälzlagerstahl auf, der eine spanabhebend gefertigte Kugellaufbahn 1a an seiner Außenseite hat. Das Kugellager weist ferner eine spanlos gefertigte äußere Lagerhülse 2 auf, die zwei Lager­ außenringe 4 übergreift, die insbesondere spanlos hergestellt sein können. Die Lageraußenrin­ ge 4 haben jeweils radial und axial nach innen weisende Schrägflächen, die als radial und axial äußere Laufbahnen für Lagerkugeln 6 dienen, die zwischen dem Lagerinnenring 1 und den beiden Lageraußenringen 4 angeordnet sind. Hierdurch ist ein Dreipunktlager gebildet.Referring to FIG. 1, the ball bearing has a bearing inner ring 1 made of hardened bearing steel, which has a Machined ball raceway 1a on its outer side. The ball bearing also has a non-cutting outer bearing sleeve 2 , which overlaps two bearing outer rings 4 , which can in particular be produced without cutting. The Lageraußenrin ge 4 each have radially and axially inwardly facing inclined surfaces which serve as radial and axial outer raceways for bearing balls 6 , which are arranged between the bearing inner ring 1 and the two bearing outer rings 4 . This creates a three-point bearing.

Besonders vorteilhaft ist es, das Kugellager mit einem vollen Satz von Lagerkugeln 6 auszu­ statten, also als vollkugeliges Lager ohne einen Kugelkäfig auszubilden. Die Lagerkugeln 6 berühren hierbei einander in Umfangsrichtung.It is particularly advantageous to equip the ball bearing with a full set of bearing balls 6 , that is, to design it as a full-spherical bearing without a ball cage. The bearing balls 6 touch each other in the circumferential direction.

Zwischen der äußeren Lagerhülse 2 und den beiden Lageraußenringen 4 ist jeweils eine Dichtung 3 aufgenommen, die an der Innenseite gegenüber dem inneren Lagerring 1 zwei Dichtlippen 3a und 3b aufweist. Die äußere Dichtlippe 3a verhindert den Eintritt von Schmutz von außen in das Lager, und die innere Dichtlippe 3b verhindert den Austritt von Schmierfett aus dem Lager nach außen. Bei der Montage wird das Kugellager mit Schmierfett für die gesamte Lebensdauer gefüllt.Between the outer bearing sleeve 2 and the two bearing outer rings 4 , a seal 3 is accommodated, which has two sealing lips 3 a and 3 b on the inside opposite the inner bearing ring 1 . The outer sealing lip 3 a prevents dirt from entering the bearing from the outside, and the inner sealing lip 3 b prevents grease from escaping from the bearing to the outside. During assembly, the ball bearing is filled with grease for the entire service life.

Die Dichtung 3 weist einen Dichtungsträger 3c aus Metall auf sowie eine, insbesondere an dessen axialer Außenseite aufgebrachte, nachgiebige Schicht 3d aus einem dämpfenden Werkstoff (Elastomer).The seal 3 has a seal carrier 3 c made of metal and a flexible layer 3 d made of a damping material (elastomer), in particular applied on its axial outer side.

Bei der Montage des Kugellagers wird die äußere Lagerhülse 2 über die Dichtungen 3 und damit über die Lageraußenringe 4 geformt, insbesondere unter Druck umgebördelt. Durch diese Bauform entsteht somit bin Dreipunktlager, in dem jede Lagerkugel 6 an drei Punkten trägt, nämlich an der radial inneren Kugellaufbahn 1a und an den beiden Schrägflächen der beiden äußeren Lagerringe 4. Dieses Lager ist aufgrund der unter Druck stehenden nachgiebi­ gen Dämpfungsschichten 3d der Dichtungen 3 axial und radial spielfrei und selbst zen­ trierend, wobei Fertigungstoleranzen leicht ausgeglichen werden können. Die elastomere Dämpfungsschicht 3d auf den Dichtungsträgern 3c wirkt als Ausgleichselement und bietet Sicherheit gegen zu hohe Vorspannungen infolge des Aufbördelns der äußeren Lagerhülse 2 und verhindert damit ein Blockieren der Lagerkugeln 6.When mounting the ball bearing, the outer bearing sleeve 2 is formed over the seals 3 and thus over the bearing outer rings 4 , in particular flanged under pressure. This design thus creates a three-point bearing, in which each bearing ball 6 carries at three points, namely on the radially inner ball race 1 a and on the two inclined surfaces of the two outer bearing rings 4 . This camp is due to the pressurized nachgiebi gene damping layers 3 d of the seals 3 axially and radially free of play and even zen trierend, manufacturing tolerances can be easily compensated. The elastomeric damping layer 3 d on the seal carriers 3 c acts as a compensating element and offers security against excessive prestressing due to the flaring of the outer bearing sleeve 2 and thus prevents the bearing balls 6 from blocking.

Bei dem Ausführungsbeispiel nach Fig. 2 tragen gleiche Teile gleiche Bezugsziffern. Der innere Lagerring 1 ist ersetzt durch eine, insbesondere spanlos hergestellte und einsatz­ gehärtete, innere Lagerhülse 5 mit einer äußeren Kugellaufbahn 5a. Diese innere Lagerhülse 5 ist mit einem Kunststoff 7 (Thermoplast oder Elastomer) ausgefüllt, der als innerer Lag­ erträger dient. Daraus ergeben sich insbesondere radiale Dämpfungseigenschaften des Lagers, wodurch stoßartige (radiale) Belastungen, wie sie u.a bei Webmaschinen auftreten, in vorteil­ hafter Weise abgeschwächt und abgefangen werden können.In the embodiment according to FIG. 2, the same parts have the same reference numbers. The inner bearing ring 1 is replaced by an inner bearing sleeve 5 , in particular machined and hardened without insert, with an outer ball race 5 a. This inner bearing sleeve 5 is filled with a plastic 7 (thermoplastic or elastomer), which serves as the inner lag erträger. This results in particular radial damping properties of the bearing, whereby shock-like (radial) loads, such as occur in looms, can be weakened and intercepted in an advantageous manner.
