Abstract
Description
Die Erfindung betrifft ein Lager mit doppelter Wälzkörperreihe.The The invention relates to a bearing with a double row of rolling elements.
Insbesondere betrifft die Erfindung ein zweireihiges Kegelrollenlager, auf welches sich die nachstehende Beschreibung ausdrücklich bezieht, ohne deshalb an allgemeinen Wert zu verlieren.Especially The invention relates to a double-row tapered roller bearing, on which The following description refers expressly, without therefore to lose general value.
Die bekannten zweireihigen Kegelrollenlager weisen eine Drehachse auf und besitzen einen Außenring mit einer Laufbahn für jede Kegelrollenreihe und zwei Innenringe, die an der Drehachse entlang hintereinander und im Bereich der jeweiligen ringförmigen Auflageflächen dicht aneinander angeordnet sind und jeweils eine Laufbahn für jede Kegelrollenreihe haben.The known double row tapered roller bearings have an axis of rotation and have an outer ring with a career for each row of tapered rollers and two inner rings that are on the axis of rotation along one another and in the region of the respective annular bearing surfaces tight are arranged one another and in each case a career for each row of tapered rollers to have.
Trotz aller Vorsicht bei der Montage der Lager der oben genannten Art, sind dieselben mit einigen Nachteilen behaftet, die auf die beiden Auflageflächen zurückzuführen sind, die zu einer strukturellen Diskontinuität des Lagers führen, und zwar vor allem hinsichtlich der Abdichtung desselben gegen äußere Einwirkungen, wie etwa Verunreinigungen.In spite of take care when mounting the bearings of the above mentioned type, they have some drawbacks that affect the two support surfaces are due which lead to a structural discontinuity of the camp, and above all with regard to the sealing of the same against external influences, such as impurities.
Der Erfindung liegt die Aufgabe zugrunde, ein Lager mit doppelter Wälzkörperreihe zu schaffen, mit dem sich die oben erwähnten Nachteile einfach und kostengünstig beseitigen lassen.Of the Invention is based on the object, a bearing with double Wälzkörperreihe to create, with the above-mentioned disadvantages simple and economical get rid of.
Erfindungsgemäß wird nun ein Lager mit doppelter Wälzkörperreihe geschaffen, das eine Drehachse aufweist und für die beiden Wälzkörperreihen jeweils einen Innenring besitzt, der koaxial zur Drehachse und dicht am Innenring der anderen Wälzkörperreihe im Bereich einer ringförmigen Auflagefläche angeordnet ist, wobei das Lager dadurch gekennzeichnet ist, dass es Abdichtungsmittel aufweist, die mit beiden Innenringen einteilig verbunden und so angeordnet sind, dass sie einen durch die beiden ringförmigen Auflageflächen gebildeten Spalt abdichtend schließen.According to the invention will now a bearing with double row of rolling elements created, which has an axis of rotation and for the two rows of rolling elements each having an inner ring which is coaxial with the axis of rotation and tight on the inner ring of the other row of rolling elements in the area of an annular bearing surface is arranged, wherein the bearing is characterized in that it has sealing means integral with both inner rings connected and arranged so that they pass one through the two annular support surfaces Close formed gap sealing.
Die Erfindung wird nachstehend an Hand der beiliegenden Zeichnungen näher beschrieben, die ein nicht beschränkendes Ausführungsbeispiel darstellen. Es zeigen:The The invention will be described below with reference to the accompanying drawings described in more detail, the one non-limiting embodiment represent. Show it:
