Abgedichtetes RadialwälzlagerSealed radial roller bearing

Die vorliegende Neuerung betrifft ein spielfreies Radialwälzlager mit zwischen einem äußeren und einem inneren Laufring angeordneten Wälzkörpern, wobei der äußere Laufring in zwei axial hintereinander angeordnete Ringteile aufgeteilt ist, die mittels eines eine Vorspannung des Lagers erzeugenden Federelementes an die Wälzkörper angedrückt sind, und mit einer Dichtung, die einen durch die Laufringe gebildeten Ringspalt gegenüber der Lagerumgebung abdichtet.The present innovation relates to a clearance-free radial rolling bearing with rolling elements arranged between an outer and an inner race, whereby the outer race is divided into two ring parts arranged axially one behind the other, which are pressed against the rolling elements by means of a spring element that generates a preload of the bearing, and with a seal that seals an annular gap formed by the races from the bearing environment.

Ein derartiges spielfreies Radialwälzlager ist beispielsweise durch die DE-A-40 16 839 bekanntgeworden.Such a clearance-free radial rolling bearing is known, for example, from DE-A-40 16 839.

Zur Vermeidung von vielen einzelnen Teilen wird neuerungsgemäß vorgeschlagen, daß die Dichtung an eines der Laufringteile und/oder an ein an dem Federelement und einem der Laufringteile abgestützten Bauteil angespritzt oder anvulkanisiert ist. Eine besonders günstige neuerungsgemäße Weiterbildung besteht darin, daß das Federelement aus gieß- oder spritzfähigem Werkstoff gebildet und einstückig mit der Dichtung verbunden ist. Dadurch wird die Verliersicherheit weiter erhöht. Natürlich ist es auch möglich, daß das Federelement ebenso wie die Dichtung an eines der Ringteile angespritzt oder anvulkanisiert ist.To avoid many individual parts, the new development proposes that the seal be molded or vulcanized onto one of the raceway parts and/or onto a component supported on the spring element and one of the raceway parts. A particularly advantageous development according to the new development is that the spring element is made of a castable or sprayable material and is connected to the seal in one piece. This further increases the security against loss. Of course, it is also possible for the spring element, like the seal, to be molded or vulcanized onto one of the ring parts.

Gemäß Anspruch 3 ist es zweckmäßig, daß das Bauteil eine beide Laufringteile umfassende Klammer ist, wobei die Dichtung an einem Radialbord der Klammer befestigt ist.According to claim 3, it is expedient that the component is a clamp enclosing both race parts, wherein the seal is attached to a radial edge of the clamp.

2554-11-DE 22554-11-EN 2

Nachstehend wird die Neuerung anhand von in drei Figuren dargestellten Ausführungsbeispielen näher erläutert. Es zeigen:The innovation is explained in more detail below using three examples of implementation. They show:

Figur 1 einen Längsschnitt durch ein neuerungsgemäßes Radialwälzlager; Figure 1 shows a longitudinal section through a radial rolling bearing according to the innovation;

Figur 2 einen Längsschnitt durch ein weiteres neuerungsgemäßes Radialwälzlager undFigure 2 shows a longitudinal section through another radial rolling bearing according to the innovation and

Figur 3 einen Längsschnitt durch ein weiteres neuerungsgemäßesFigure 3 shows a longitudinal section through another innovative

Radialwälzlager.Radial rolling bearings.

Ein neuerungsgemäßes Lager nach Figur 1 ist auf einer Welle 1 und in einer Gehäusebohrung 2 eingesetzt. Das Lager besteht aus einem inneren Laufring 3 und einem äußeren Laufring 4, der in zwei axial hintereinander angeordnete Ringteile 5, 6 aufgeteilt ist, die durch eine hülsenförmige Klammer 7 umgriffen und zusammengehalten werden. Das Ringteil 6 stützt sich an einem Radialbord 8 der Klammer 7 in axialer Richtung ab, wobei zwischen dem Ringteil 5 und einem Radialbord 9 der Klammer 7 ein elastisch vorgespanntes Federelement 10 aus polymeren! Werkstoff angeordnet ist. An Laufrillen 11, 12 der Laufringe 3, 4 wälzen Kugeln 13 ab, die aufgrund des vorgespannten Federelementes 10 zwischen diesen Laufrillen 11, 12 eingespannt sind. Der Radialbord 9 ist an einer axialen Verlängerung 14 der Klammer 7 vorgesehen und trägt eine Dichtung 15, die aufgespritzt oder aufvulkanisiert ist, und die einstückig mit dem Federelement 10 verbunden ist. Dichtlippen 16 der Dichtung 15 liegen an der Welle 1 an. Bei diesem Ausführungsbeispiel sind das Laufringteil 5, das Federelement 10, die Klammer 7 und die Dichtung 15 deshalb verliersicher miteinander verbunden, weil das Federelement 10 an dem Laufringteil 5 und der Klammer 7 haftet und einstückig mit der Dichtung 15 verbunden ist.A bearing according to the innovation according to Figure 1 is installed on a shaft 1 and in a housing bore 2. The bearing consists of an inner race 3 and an outer race 4, which is divided into two ring parts 5, 6 arranged axially one behind the other, which are encompassed and held together by a sleeve-shaped clamp 7. The ring part 6 is supported on a radial edge 8 of the clamp 7 in the axial direction, with an elastically pre-stressed spring element 10 made of polymer material being arranged between the ring part 5 and a radial edge 9 of the clamp 7. Balls 13 roll on raceway grooves 11, 12 of the raceways 3, 4, and are clamped between these raceway grooves 11, 12 due to the pre-stressed spring element 10. The radial flange 9 is provided on an axial extension 14 of the clamp 7 and carries a seal 15 which is sprayed or vulcanized on and is integrally connected to the spring element 10. Sealing lips 16 of the seal 15 rest against the shaft 1. In this embodiment, the race part 5, the spring element 10, the clamp 7 and the seal 15 are connected to one another in a captive manner because the spring element 10 adheres to the race part 5 and the clamp 7 and is integrally connected to the seal 15.

Das in Figur 2 dargestellte neuerungsgemäße Lager weist einen inneren Laufring 17 und einen äußeren Laufring 18 auf, der in zwei axial hintereinander angeordnete Ringteile 19, 20 unterteilt ist. Zwischen dem Ringteil 18 und einem Radialbord 21, der an eine Axialverlängerung 22 des Ringteiles 20 anschließt, ist ein Federelement 23 aus polymeren!The new bearing shown in Figure 2 has an inner race 17 and an outer race 18, which is divided into two ring parts 19, 20 arranged axially one behind the other. Between the ring part 18 and a radial rim 21, which adjoins an axial extension 22 of the ring part 20, there is a spring element 23 made of polymer!

2554-11-DE2554-11-EN

Werkstoff angeordnet. Das Federelement 23 ist einerseits an dem Ringteil 19 und andererseits an einem ringförmigen profilierten Blechteil 24 abgestützt, das sich wiederum an dem Radialbord 21 abstützt. Radial innenliegend ist an dem Blechteil 24 ein Dichtring 25 mit Dichtlippen 26 ausgebildet, die an einer Welle 27 anliegen. Ebenso wie in dem Ausführungsbeispiel nach Figur 1 ist das Federelement 23 einstückig mit der Dichtung 25 verbunden. Das äußere Lauf ringteil 20 ist mit seiner axialen Verlängerung 22 in einer Gehäusebohrung 28 untergebracht. An Laufrillen 29, 30 der Laufringe 17, 18 wälzen Kugeln 31 ab, die aufgrund des vorgespannten Federelementes 23 zwischen den Laufrillen 29, 30 eingespannt sind.Material. The spring element 23 is supported on the one hand on the ring part 19 and on the other hand on an annular profiled sheet metal part 24, which in turn is supported on the radial rim 21. Radially on the inside of the sheet metal part 24 there is a sealing ring 25 with sealing lips 26, which rest on a shaft 27. Just as in the embodiment according to Figure 1, the spring element 23 is connected in one piece to the seal 25. The outer race part 20 is housed with its axial extension 22 in a housing bore 28. Balls 31 roll on race grooves 29, 30 of the race rings 17, 18, which are clamped between the race grooves 29, 30 due to the pre-stressed spring element 23.

Das in der Figur 3 dargestellte neuerungsgemäße Radialwälzlager unterscheidet sich von dem aus der Figur 2 im wesentlichen dadurch, daß das Federelement 23 unmittelbar an dem Radialbord 21 der axialen Verlängerung 22 abgestützt ist. Außerdem ist die Dichtung 25 an einem Radialbord 32 einer axialen Verlängerung 33 des Ringteiles 19 vorgesehen. Auf diese Weise entfällt das ringförmige profilierte Blechteil aus dem Ausführungsbeispiel nach Figur 2.The new radial roller bearing shown in Figure 3 differs from that in Figure 2 essentially in that the spring element 23 is supported directly on the radial edge 21 of the axial extension 22. In addition, the seal 25 is provided on a radial edge 32 of an axial extension 33 of the ring part 19. In this way, the ring-shaped profiled sheet metal part from the embodiment according to Figure 2 is omitted.
