Description

Kegelrollenlager Die Erfindung betrifft ein Kegelrollenlager mit einem aus zwei konzentrisch zueinander angeordneten Ringen und einer elastischen Zwischenlage gebildeten äußeren Lagerlaufring.Tapered roller bearing The invention relates to a tapered roller bearing with a made of two concentrically arranged rings and an elastic intermediate layer formed outer bearing race.

Kegelrollenlager werden meistens paarweise eingebaut, und da diese Lager infolge des Kegelwinkels und der Linienberührung zwischen den Rollen und der Laufbahn in axialer Richtung starr sind, so sind sie aus dem gleichen Grunde auch sehr empfindlich in bezug auf die richtige Einstellung der Lager zueinander. Zu großes Lagerspiel ergibt ungünstige Laufeigenschaften, während die Lager bei zu dichter Einstellung heißlaufen und durch Überbeanspruchung zerstört werden. Besonders große Einstellungsschwierigkeiten ergeben sich, wenn der Abstand der Lager zueinander groß ist, wie z. B. bei Kurbelwellenlagerungen, da in diesem Fall durch Temperaturschwankungen Abstandsveränderungen auftreten, die durch die Lager selbst nicht ausgeglichen werden können.Tapered roller bearings are usually installed in pairs, and as these Bearing due to the taper angle and the line contact between the rollers and the Raceways are rigid in the axial direction, so they are for the same reason very sensitive to the correct adjustment of the bearings to each other. to large bearing play results in unfavorable running properties, while the bearings are too overheating and can be destroyed by overstressing. Particularly great adjustment difficulties arise when the distance between the bearings is large, such as B. with crankshaft bearings, because in this case due to temperature fluctuations Changes in distance occur that are not compensated for by the bearings themselves can.

Die Anwendung von elastischen Zwischenlagen zwischen den Laufringen von Wälzlagern und dem Gehäuse bzw. zwischen den aus zwei konzentrischen ungeteilten Ringen gebildeten Laufring zum Ausgleich von Fluchtungsfehlern bzw. zum Zweck der Geräuschdämpfung ist an sich bekannt. So ist bei einer bekannten Ausführung eines Kugel- oder Rollenlagers zur Erzielung einer elektrischen Isolierung der äußere Laufring aus mindestens zwei konzentrischen Ringen mit parallel zur Welle liegender Teilungsebene mit Zwischenlagen aus eingegossenem oder eingepreßtem Isoliermaterial gebildet. Diese Zwischenlage hat keine feste Haftverbindung mit den Ringen, so daß der Einbau des Lagers als Führungslager entweder starr oder als sogenanntes Wanderlager, bei welchem der Innenring auf der Welle befestigt ist, während der Außenring mit Bewegungsfreiheit in axialer Richtung im Lagergehäuse montiert ist, erfolgen muß.The use of elastic intermediate layers between the races of rolling bearings and the housing or between the two concentric undivided Rings formed race to compensate for misalignments or for the purpose of Noise attenuation is known per se. So is in a known embodiment of a Ball or roller bearing to achieve electrical insulation of the outer Running ring made of at least two concentric rings with one lying parallel to the shaft Partition level with intermediate layers made of cast or pressed-in insulating material educated. This intermediate layer has no firm adhesive connection with the rings, so that the installation of the bearing as a guide bearing either rigid or as a so-called moving bearing, in which the inner ring is attached to the shaft, while the outer ring is attached to the shaft Freedom of movement is mounted in the bearing housing in the axial direction, must take place.

Bei einem kugelig geführten Wälzlager ist auch schon vorgeschlagen worden, zwischen dem äußeren Lagerlaufring und einem besonderen Stützring eine das Lager in einer dünnen Kugelzone umgebende, elastische Schicht vorzusehen, um bei geringen Neigungen Kantenpressungen des Lagers zu vermeiden und damit die Belastbarkeit des Lagers zu erhöhen.In the case of a spherically guided roller bearing, this has already been proposed between the outer bearing race and a special support ring a das To provide an elastic layer surrounding the bearing in a thin spherical zone in order to at low inclinations to avoid edge pressures of the bearing and thus the load capacity of the camp to increase.

Die Erfindung hat sich die Aufgabe gestellt, ein Kegelrollenlager mit einem aus zwei konzentrisch zueinander angeordneten Ringen und einer elastischen Zwischenlage gebildeten äußeren Lagerlaufring zu schaffen, das in axialer Richtung annähernd linear zur Größe der Schubkraft nachgiebig, in radialer Richtung jedoch fast unnachgiebig ist. Hierbei soll der äußere Ringteil des Außenlaufringes im Gehäuse fest angeordnet sein und der innere Ringteil des Außenlaufringes mit dem Lager nach Aufhebung einer axialen Lagerbelastung durch die Elastizität der elastischen Zwischenlage seine ursprüngliche Stellung gegenüber dem äußeren Ringteil wieder einnehmen. Es soll ferner Vorsorge getroffen werden, daß beim Auftreten von Axialkräften eine Überbeanspruchung der elastischen Zwischenlage verhindert wird.The invention has the task of providing a tapered roller bearing with one of two concentrically arranged rings and one elastic To create intermediate layer formed outer bearing race in the axial direction approximately linear to the magnitude of the thrust force, but flexible in the radial direction is almost adamant. Here, the outer ring part of the outer race should be in the housing be fixed and the inner ring part of the outer race with the bearing after Elimination of an axial bearing load due to the elasticity of the elastic intermediate layer resume its original position with respect to the outer ring part. It precautions should also be taken that when axial forces occur, a Overstressing of the elastic intermediate layer is prevented.

Diese Forderungen werden gemäß der Erfindung dadurch erfüllt, daß die Teilungsebene des äußeren Lagerlaufringes des Kegelrollenlagers in Richtung der Kegelrollenachse geneigt verläuft und die Ringe durch eine einvulkanisierte Gummischicht miteinander verbunden sind.These requirements are met according to the invention in that the division plane of the outer bearing race of the tapered roller bearing in the direction the tapered roller axis is inclined and the rings are vulcanized in Rubber layer are connected to each other.

Durch die geneigte Anordnung der zwischen den beiden äußeren Lagerlaufringen einvulkanisierten Gummischicht kann diese bei axialer Belastung des Lagers nicht überbeansprucht werden, da sie nicht ausschließlich auf Schub, sondern auch auf Druck beansprucht wird.Due to the inclined arrangement of the between the two outer bearing races Vulcanized rubber layer cannot do this if the bearing is axially loaded Be overused as they are not solely based on thrust but also on Pressure is stressed.

Die Zeichnung veranschaulicht eine Ausführungsform des erfindungsgemäßen Kegelrollenlagers im Schnitt.The drawing illustrates an embodiment of the invention Tapered roller bearing in section.

Die Kegelrollen 1 sind in einem Fensterkäfig 2 einzeln geführt. Der innere Laufring 3 ist als Bordring ausgebildet. Der äußere Laufring besteht aus zwei konzentrisch zueinander angeordneten Ringen 4 und 5, die durch eine einvulkanisierte Gummischicht 6 vereinigt sind.The tapered rollers 1 are individually guided in a window cage 2. Of the inner race 3 is designed as a flange ring. The outer race consists of two concentrically arranged rings 4 and 5, which are vulcanized in by a Rubber layer 6 are combined.
