Description

Die Erfindung bezieht sich auf ein Schrägschulterlager, insbesondere Schrägkugellager als Kupplungsausrücklager, dessen Außenring mit einem Druckflansch ausgerüstet und von einem Dichtring umgeben ist.The invention relates to a Schrägschulterlager, in particular angular contact ball bearings as a clutch release bearing, the outer ring is equipped with a pressure flange and surrounded by a sealing ring.

Derartige Schrägkugellager sind allgemein bekannt. Sie sind als Kupplungsausrücklager üblich. Es besteht jedoch das Problem, dass aufgrund ihres Einbaus in einer Kupplungsglocke einer Brennkraftmaschine mit anschließendem Getriebe die Temperatur des Schrägkugellagers unerwünscht ansteigt.Such angular contact ball bearings are well known. They are common as a clutch release bearing. However, there is the problem that due to their installation in a clutch bell of an internal combustion engine with subsequent transmission, the temperature of the angular contact ball bearing increases undesirably.

Aufgabe der Erfindung ist es, das Schrägschulterlager, insbesondere Schrägkugellager so zu modifizieren, dass die Temperatur des Lagers verringert wird.The object of the invention is to modify the oblique shoulder bearing, in particular angular contact ball bearings so that the temperature of the bearing is reduced.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass der Dichtring eine nach außen gerichtete Rippe aufweist. Durch diese umlaufende Rippe wird der das Lager umgebende Luftstrom zumindest teilweise nach außen radial abgelenkt, so dass neue Luft nachfließen kann, wodurch der Dichtring und damit das Lager gekühlt werden.According to the invention the object is achieved in that the sealing ring has an outwardly directed rib. As a result of this circumferential rib, the air flow surrounding the bearing is at least partially deflected radially outwards so that new air can flow in, as a result of which the sealing ring and thus the bearing are cooled.

Der Dichtring kann anstelle der Rippe auch Schaufeln aufweisen, wobei die Schaufeln über den Umfang des Dichtringes verteilt sind. In einfacher Weise sind die Rippe oder die Schaufeln an dem dem Druckflansch benachbarten Ende des Dichtringes angeordnet, da dort die Rippe leicht nach außen gebördelt werden kann. In diese Rippe können Einschnitte vorgenommen werden, wobei diese Segmente zwischen den Einschnitten durch Verbiegen leicht zu Schaufeln geformt werden können.The sealing ring may also have blades instead of the rib, wherein the blades are distributed over the circumference of the sealing ring. In a simple manner, the rib or the blades are arranged on the pressure flange adjacent the end of the sealing ring, since there the rib can be easily crimped outwards. In this rib cuts can be made, which segments can be easily formed between the cuts by bending to blades.

Die Erfindung ist in den Zeichnungen beschrieben:

  • • 1 zeigt einen Schnitt durch ein Schrägkugellager, bei dem der Dichtring eine Rippe aufweist,
  • • 2 zeigt eine Draufsicht auf ein Schrägkugellager mit Einschnitten in die Rippe,
  • • 3 zeigt eine Seitenansicht mit Schaufeln und
  • • 4 zeigt eine perspektivische Ansicht gemäß 3.
The invention is described in the drawings:
  • • 1 shows a section through an angular contact ball bearing, in which the sealing ring has a rib,
  • • 2 shows a plan view of an angular contact ball bearing with cuts in the rib,
  • • 3 shows a side view with blades and
  • • 4 shows a perspective view according to 3 ,

In den 1 bis 4 ist, soweit im Einzelnen dargestellt, mit 1 allgemein ein Schrägkugellager bezeichnet, das einen Außenring 2 und einen Innenring 3 aufweist. Der Außenring 2 weist einen nach innen gerichteten Druckflansch 4 auf, der durch Verformen des Außenringes 2 hergestellt ist. Der Außenring 2 ist von einem Dichtring 5 umgeben, wobei der Dichtring 5 eine Dichtlippe 6 aufweist, die auf der dem Druckflansch 4 abgewandten Ende bis zum Innenring 3 reicht. An dem dem Druckflansch 4 benachbarten Ende des Dichtringes 5 ist eine Rippe 7 angeformt, die winklig vom Außenring 2 abstehend geformt ist. Dadurch, dass der Außenring 2 über den Druckflansch 4 Kontakt zu Betätigungselementen einer Kupplung hat, die mit Brennkraftmaschinendrehzahl umlaufen, dreht sich auch der Dichtring 5 mit, so dass durch die Rippe 7 ein radial nach außen gerichteter Luftstrom erzeugt wird, der eine Kühlung des Schrägkugellagers 1 bewirkt.In the 1 to 4 is, as far as shown in detail, 1 generally designates an angular contact ball bearing, which has an outer ring 2 and an inner ring 3. The outer ring 2 has an inwardly directed pressure flange 4, which is made by deforming the outer ring 2. The outer ring 2 is surrounded by a sealing ring 5, wherein the sealing ring 5 has a sealing lip 6, which extends on the end facing away from the pressure flange 4 to the inner ring 3. At the pressure flange 4 adjacent end of the sealing ring 5, a rib 7 is formed, which is formed at an angle from the outer ring 2 projecting. Characterized in that the outer ring 2 has contact via the pressure flange 4 to actuators of a clutch, which rotate at engine speed, and the sealing ring 5 rotates so that a radially outwardly directed air flow is generated by the rib 7, which is a cooling of the angular contact ball bearing 1 causes.

In den 2 bis 4 weist die Rippe 7 Einschnitte auf, wodurch, wie in 2 dargestellt, Segmente 8 entstehen, die eine höhere Luftbewegung bewirken In den 3 und 4 sind die Segmente 8 verdreht, so dass Schaufeln 9 vorliegen, die eine noch höhere Luftbewegung und damit eine noch höhere Kühlung des Schrägkugellagers 1 bewirken.In the 2 to 4 has the rib 7 cuts, which, as in 2 shown, segments 8 arise that cause a higher air movement In the 3 and 4 are the segments 8 twisted so that blades 9 are present, which cause an even higher air movement and thus an even higher cooling of the angular contact ball bearing 1.
