Description
Radial-Zylinderrollenlager Bei den bekannten Radial-Zylinderrollenlagern sind die festen oder losen Borde mit gleicher Höhe ausgeführt. Dies bringt den Nachteil mit sich, daß diese Borde nur geringe Axialkräfte aufnehmen können. Radial cylindrical roller bearings With the known radial cylindrical roller bearings the fixed or loose shelves are of the same height. This brings the disadvantage with it that these boards can only absorb small axial forces.
Dieser Nachteil ist bei einem Radial-Zylinderrollenlager neuerungsgemäß dadurch behoben, daß zwei einander im Lagerquerschnitt diagonal gegenüberliegende Borde höher als der oder die übrigen Borde ausgeführt sind. Durch die Erhöhung dieser Borde entsteht eine Vergrößerung der Berührungsflächen zwischen diesen und den Rollenstirnflächen und dadurch auch bei großer Axialbelastung eine Verringerung der spezifischen Flächenpressung zwischen den Borden und den Rollenstirnflächen, welche die Belastbarkeit in axialer Richtung erhöht. This disadvantage is in accordance with the innovation in a radial cylindrical roller bearing corrected by the fact that two diagonally opposite each other in the bearing cross-section Shelves are higher than the other shelf or shelves. By increasing this Borde creates an enlargement of the contact surfaces between these and the roller end faces and thus a reduction in the specific surface pressure even with high axial loads between the ribs and the roller end faces, which increase the load capacity in the axial direction Direction increased.
In weiterer Ausgestaltung der Neuerung sind die Stege des Käfigs im Bereich der Rollen wenigstens einmal abgekröpft. Dadurch sind die Rollen, da sie beinahe in ihrem ganzen Durchmesser durch die Käfigstege umfaßt sind, auch bei einwirkenden Kippkräften sicher geführt und es ist außerdem ein größerer Raum für das Schmiermittel geschaffen. Bei mehrteiligen Käfige mit gekröpften Käfigstegen sind die Verbindungsmittel, wie beispielsweise Nieten, innerhalb oder außerhalb des Rollent kreises angeordnet. Dadurch ist es möglich, die Anzahl der Rollen und damit die Tragfähigkeit des Wälzlagers zu erhöhen. The bars of the cage are a further refinement of the innovation bent at least once in the area of the rollers. Because of that, the roles are there almost all of their diameter is enclosed by the cage bars, also at acting tilting forces and there is also a larger space for created the lubricant. For multi-part cages with cranked cage bars are the connecting means, such as Rivets, inside or arranged outside of the Rollent circle. This makes it possible to change the number of the rollers and thus the load-bearing capacity of the rolling bearing.
Die Neuerung ist für alle bekannten Rollenlagertypen ausführbar.The innovation can be implemented for all known roller bearing types.
Ein Ausführungsbeispiel eines neuerungsgemäßen Radialzylinderrollenlagers ist in der nachstehenden Beschreibung an Hand der Zeichnung näher erläutert. In der Zeichnung ist die Fig. 1 ein Schnitt durch ein Lager der Zylinderrollenlagertype NJ, die Fig. 2 ein solcher durch den dazugehörigen Käfig, der der Übersicht halber für sich dargestellt ist. An embodiment of a radial cylindrical roller bearing according to the innovation is explained in more detail in the following description with reference to the drawing. In of the drawings, Fig. 1 is a section through a bearing of the cylindrical roller bearing type NJ, Fig. 2 one such by the associated cage, for the sake of clarity is shown for itself.
Zwischen dem Außenlaufring 1 und dem Innenlaufring 2 sind die Zylinderrollen
3 angeordnet. Der Bord 4 des Außenlaufrings 1 und der diagonal gegenüberliegende
Bord 5 des Innenlaufrings 2
Der neuerungsgemäße Käfig ist den jeweiligen Erfordernissen entsprechend als ein-oder mehrteiliger Blech-oder Massivkäfig aus jedem beliebigem zweckmäßigen Werkstoff oder einer Kombination von Werkstoffen herstellbar. The cage according to the innovation is according to the respective requirements as a one-part or multi-part sheet metal or solid cage made of any suitable Material or a combination of materials can be produced.
