Description

Die Neuerung "betrifft sin Wälzlager mit einem die Wälzkörper aufnehmenden Käfig und wenigstens einer an diesem befestigten, mit dem Lagerinnen- und-außenring zusammenwirkenden Dichtung.The innovation "concerns rolling bearings with a the rolling elements receiving cage and at least one attached to this, with the bearing inner and outer ring cooperating seal.

Bei einem bekannten Käfig dieser Art (DE-OS 22 10 820) ist die Dichtung am Käfig angeklebt oder anvulkanisiert, was in jedem Fall den Herstellungsaufwand durch einen entsprechenden zusätzlichen Arbeitsgang erhöht und hinsichtlich der Sicherheit der Verbindung zwischen Käfig und Dichtung zu wünschen übrig läßt. Es ist auch schon bekannt, die Dichtung am Käfig mit Hilfe von Zapfen zu befestigen, die in Käfigauasparungen eingreifen (DE-OS 21 45 013), wobei aber auch hier trotz vorgesehener ültraschallschweißung kein sicherer Halt erzielbar ist.In a known cage of this type (DE-OS 22 10 820) the seal is glued to the cage or vulcanized, which in any case increases the manufacturing effort by a corresponding additional operation increased and in terms of the security of the connection between the cage and seal to be desired leaves. It is also already known to attach the seal to the cage with the help of pegs in cage openings intervene (DE-OS 21 45 013), but here too despite the planned ultrasonic welding no secure hold can be achieved.

Demnach liegt der Neuerung die Aufgabe zugrunde, diese Mängel zu beseitigen und ein Wälzlager der eingangs geschilderten Art zu schaffen, bei dem ohne erhöhten Arbeitsaufwand eine sichere Verbindung von Dichtung und Käfig gewährleistet ist.Accordingly, the innovation is based on the task of eliminating these shortcomings and a rolling bearing of the To create the type described above, in which a secure connection of without increased work Seal and cage is guaranteed.

Die Neuerung löst die gestellte Aufgabe dadurch, daß die Dichtung stirnseitig einen gegebenenfalls unterbrochenen Ringwulst mit einem von einem verdickten, vorzugsweise nach einem Kreis geformten Kopf und einemThe innovation solves the problem posed by the fact that the seal has a front side if necessary interrupted annular bead with one of a thickened, preferably shaped after a circle head and a

verjüngten Hals gebildeten Querschnitt besitzt undhas a tapered neck formed cross-section and

der Käfig eine dem Hingwulst angepaßte stirnseitige Nut aufweist. Es braucht also nur die Dichtung an den Käfig angedrückt zu werden, um eine schnappverschlußartige Verbindung zwischen den beiden Teilen ■ herzustellen, bei der keine Gefahr eines Lösens im Betrieb besteht und die auch keinen zusätzlichen Arbeitsgang erfordert.the cage has an end-face groove adapted to the Hingwulst. So all you need is the seal to be pressed against the cage to create a snap-lock connection between the two parts with which there is no risk of loosening during operation and which also does not require any additional operation requires.

Um ein Einschnappen des Ringwulstes in die Nut des Käfigs auch bei weniger elastischen Werkstücken zu ermöglichen, weist der Ringwulst in seinem den Querschnittskopf bildenden Teil einen Umfangsschlitz auf. Aus dem gleichen Grunde kann der Käfig im Nahbereich der Nut mit konzentrischen Schlitzen versehen ε eic.To ensure that the annular bead snaps into the groove of the cage even with less elastic workpieces to enable, the annular bead has a circumferential slot in its part forming the cross-sectional head. For the same reason, the cage can be provided with concentric slots in the vicinity of the groove.

Die Zeichnung zeigt als Ausführungsbeispiel einen Teil eines neuerungsgemäßen Kugellagers im Schnitt nach einer durch die Lagerachse verlaufenden Ebene, wobei Kugeln sowie der Lagerinnen- und -außenring nur strichpunktiert angedeutet sind.As an exemplary embodiment, the drawing shows part of a ball bearing according to the invention Section after a plane running through the bearing axis, with balls and the bearing inner and outer ring are only indicated by dash-dotted lines.

Das Kugellager weist einen Lagerinnenring und einen Lageraußenring 2 auf, zwischen denen als Wälzkörper Kugeln 3 angeordnet sind. Die Kugeln 3 sind in. einem Käfig 4 gehalten, an dem eine sowohl mit dem Lagerinnenring i als auch mit dem Lageraußenring 2 zusammenwirkende Dichtung 5 befestigt ist. Eine gleiche Dichtung könnte auch an der anderen nicht dargestellten Lagerseite vorgesehen sein.The ball bearing has an inner ring and a bearing outer ring 2, between which balls 3 are arranged as rolling elements. The balls 3 are held in. A cage 4, on which one with both the bearing inner ring i and with the bearing outer ring 2 cooperating seal 5 is attached. The same seal could also be used on the other, not shown Be provided on the bearing side.

Die Dichtung 5 besitzt stirnseitig einen Ringwulst 6, dessen Querschnitt von einem verdickten, nach einem Kreis geformten Kopf 7 und einem verjüngten Hals 8 gebildet wird. Der Käfig 4 ist mit einer dem Ringwulst 6 angepaßten stirnseitigen Nut 9 versehen, so daß Dichtung 5 und Käfig 4 schnappverschlußartig verbunden werden, können. Zur Erhöhung der elastischenThe end face of the seal 5 has an annular bead 6, the cross-section of which is of a thickened, after a circle shaped head 7 and a tapered neck 8 is formed. The cage 4 is with one of the Annular bead 6 adapted end-face groove 9 is provided so that seal 5 and cage 4 snap-lock-like can be connected. To increase the elastic

Nachgie'bigkeit des Ringwulstes 6 und des Käfigs 4 in der Nutumgebung weist der Ringwiilst 6 in seinem den Querschnittskopf 7 bildenden Teil einen Umfangsschlitz 10 auf, während der Käfig 4 im Nahbereich der Nut 9 mit konzentrischen Schlitzen 11 versehen ist.Resilience of the annular bead 6 and of the cage 4 in the vicinity of the groove, the annular wiilst 6 has a circumferential slot in its part forming the cross-sectional head 7 10, while the cage 4 in the vicinity of the Groove 9 is provided with concentric slots 11.
