Abstract

In order, in a gasket with a disc-like shape or cover, especially for rolling bearings, to make it possible for it to snap simply and reliably into the retaining groove of a bearing ring in the case of any possibility of installation, it is proposed that the covering disc (4) or cover (10) possesses at least one radially offset peripheral groove (6,7) on each end face in the region of the snap-in point, the depth of the grooves being 50 to 80 % of the thickness of the covering disc. <IMAGE>

Description

Die Neuerung bezieht sich auf eine Dichtung oder einen Deckel nach dem Oberbegriff des Anspruchs 1.The innovation relates to a seal or one Lid according to the preamble of claim 1.

Eine Dichtung der angeführten Art ist aus der GB-PS 961 563 ersichtlich. Die dargestellte Dichtung kann zwar, da nur sie aus einer einfachen Scheibe besteht, ohne vorherige Seitenorientierung in die Haltenut bei­ der Stirnflächen eines Wälzlagers eingebaut werden, beim Einschnappen in die Nut ergeben sich aber Schwie­ rigkeiten. Die Deckscheibe ist nämlich relativ steif und läßt sich daher nur schwer einschnappen. Wenn des­ halb die Schnapptiefe zu gering ausgeführt wird, kann die Deckscheibe wieder herausfallen. Zur Verbesserung dieses Problems wird in der FR-PS 13 13 626 bereits eine Dichtung vorgeschlagen, die im Befesti­ gungsbereich eine Nut besitzt. Dadurch wird zwar die Elastizität erhöht, der rein radiale Abschnitt im Nut­ bereich beschwert aber immer noch im hohen Umfang die Elastizität.A seal of the type mentioned is from the GB-PS 961 563 can be seen. The seal shown can because only it consists of a simple disc, into the holding groove without prior page orientation the end faces of a rolling bearing are installed, when snapping into the groove, however, there is difficulty difficulties. The cover plate is namely relatively stiff and is therefore difficult to snap into. If the half the snap depth is too low the cover plate will fall out again. For improvement this problem is already in FR-PS 13 13 626 proposed a seal in the mounting area has a groove. This will make the Elasticity increased, the purely radial section in the groove area still complains to a large extent Elasticity.

Es ist daher Aufgabe der Neuerung eine Deckscheibe oder einen Deckel vorzuschlagen, die bzw. der die oben genannten Nachteile nicht besitzt und bei beliebiger Einbaumöglichkeit ein einfaches und sicheres Ein­ schnappen in die Haltenut eines Laufrings ermöglicht.It is therefore the task of the innovation of a cover plate or propose a lid, the one above does not have mentioned disadvantages and with any Installation possibility a simple and safe installation snap into the retaining groove of a race allows.

Die Neuerung wird anhand der kennzeichnenden Merkmale des Anspruchs 1 näher dargestellt. Der Anspruch 2 ent­ hält eine spezielle Ausgestaltung. The innovation is based on the characteristic features of claim 1 shown in more detail. The claim 2 ent holds a special design.  

Durch die Merkmale des Anspruchs 1 ergibt sich im Ein­ schnappbereich der Deckscheibe in eine Befestigungsnut einerseits ein so elastischer Abschnitt, daß sich keine Schwierigkeiten beim Einschnappen ergeben, ande­ rerseits aber trotzdem eine sichere Befestigung. Er­ reicht wird dies insbesondere durch die beiden Nuten, die durch einen schräg verlaufenden Steg voneinander getrennt sind. Dieser schräg verlaufende Steg er­ möglicht es, daß der Schnappwulst relativ leicht nach innen abgebogen werden kann. Die Versteifung wird da­ durch wesentlich herabgesetzt. Da der Schnappwulst etwa so hoch ist wie die Dicke der Deckscheibe bleibt diese aber relativ stabil und ermöglicht einen festen Sitz in der Befestigungsnut.The features of claim 1 result in a snap area of the cover plate into a fastening groove on the one hand such an elastic section that no snapping difficulties, others on the other hand, however, secure attachment. He this is particularly achieved through the two grooves, the one another by an inclined web are separated. This sloping bridge it is possible that the snap bead follows relatively easily can be turned inside. The stiffening is there by significantly reduced. Because the snap bead is about as high as the thickness of the cover plate remains but this is relatively stable and enables a firm one Seat in the mounting groove.

Der schräge Verbindungssteg ist dann elastisch genug aber andererseits stabil genug, wenn seine Breite 30 bis 40% der Dicke der Deckscheibe beträgt.The sloping connecting web is then elastic enough but stable enough if its width is 30 to 40% of the thickness of the cover plate.

Die Neuerung wird anhand von vier Figuren näher erläu­ tert.The innovation is explained in more detail using four figures tert.

Fig. 1 zeigt einen Teilquerschnitt durch ein Kugella­ ger mit der erfindungsgemäßen Deckscheibe, Fig. 1 shows a partial cross section through a Kugella ger with the inventive cover disc,

Fig. 2 zeigt eine Deckscheibe nach Fig. 1 in ver­ größerter Ausführung,1 Fig. 2 shows a cover plate according to Fig. Ver größerter in execution,

Fig. 3 zeigt eine Variante zur Deckscheibe nach Fig. 2, Fig. 3 shows a variant of cover plate of FIG. 2,

Fig. 4 zeigt einen Teilquerschnitt durch ein Kugella­ ger mit erfindungsgemäßem Deckel. Fig. 4 shows a partial cross section through a Kugella ger with the lid according to the invention.

In Fig. 1 ist der Außenring mit 1 und der Innenring mit 2 bezeichnet. Dazwischen sind die Wälzkörper 3 an­ geordnet. Zu beiden Seiten der Wälzkörper sind Deck­ scheiben 4 vorgesehen, die in Nuten 5 des Außenrings 1 eingeschnappt sind. Damit sich keine Schwierigkeiten beim Einschnappen der Deckscheiben 4 ergeben, aber trotzdem eine sichere Befestigung erfolgt, sind die Deckscheiben 4 mit Nuten 6 und 7 versehen, die durch einen schräg verlaufenden Steg 8 voneinander getrennt sind (s. Fig. 2 und 3). Dieser Steg 8 ermöglicht es, daß der Schnappwulst 9 leicht nach innen abgebogen werden kann, da die Versteifung durch die Nuten 6 und 7 herabgesetzt ist. Da der Schnappwulst 9 etwa so hoch ist, wie die Dicke der Deckscheibe, bleibt diese re­ lativ stabil und ermöglicht einen festen Sitz in der Nut 5 des Außenringes 1. Der Steg 8 ist dann elastisch aber auch stabil genug, wenn seine Breite 30% bis 40% der Dicke der Deckscheibe 4 beträgt.In Fig. 1, the outer ring is designated 1 and the inner ring with 2 . In between, the rolling elements 3 are arranged. Decks 4 are provided on both sides of the rolling elements, which are snapped into grooves 5 of the outer ring 1 . So that there are no difficulties in snapping the cover disks 4 , but nevertheless secure fastening takes place, the cover disks 4 are provided with grooves 6 and 7 , which are separated from one another by an inclined web 8 (see FIGS. 2 and 3). This web 8 enables the snap bead 9 to be easily bent inwards, since the stiffening is reduced by the grooves 6 and 7 . Since the snap bead 9 is approximately as high as the thickness of the cover plate, it remains relatively stable and enables a firm fit in the groove 5 of the outer ring 1 . The web 8 is elastic but also stable enough if its width is 30% to 40% of the thickness of the cover plate 4 .

Fig. 4 zeigt einen Teilquerschnitt durch ein Kugella­ ger, das an Stelle der Deckscheibe einseitig mit einem Deckel 10 verschlossen ist. Der Innenring 2 ist gegen­ über dem Außenring 1 schmäler ausgeführt. Um die Wälz­ körper 3 vor Schmutz zu schützen, ist in der Nut 5 des Außenrings 1 ein Deckel 10 eingeschnappt. Zur Erleich­ terung des Einschnappens weist der Deckel 10 wie die vorbeschriebenen Deckscheiben zwei Nuten 6 und 7 auf, die von einem Steg 8 voneinander getrennt sind und so das Einschnappen des Schnappwulstes 9 in die Nut 5 er­ möglichen. Fig. 4 shows a partial cross section through a Kugella ger, which is closed on one side with a cover 10 instead of the cover plate. The inner ring 2 is made narrower than the outer ring 1 . In order to protect the rolling body 3 from dirt, a cover 10 is snapped into the groove 5 of the outer ring 1 . To facilitate the snap-in, the cover 10, like the cover disks described above, has two grooves 6 and 7 , which are separated from one another by a web 8 and thus enable the snap-in bead 9 to snap into the groove 5 .
