Aufgabe der ErfindungObject of the invention
Vor diesem Hintergrund liegt der Erfindung die Aufgabe zugrunde, sowohl axial als auch radial eine optimale Abstützung der Lagerstelle in Abhängigkeit von der Temperatur zu gewährleisten, ohne die Lageranordnung wesentlich komplexer zu gestalten.Against this background, the invention has the object, both axially and radially to ensure optimum support of the bearing as a function of temperature, without making the bearing assembly much more complex.
Zusammenfassung der Erfindung Summary of the invention
Zur Lösung dieser Aufgabe wird bei einem Wälzlager zur Aufnahme von Axial- und Radialbelastungen, bestehend aus einem Lagerinnenring und einem Lageraußenring sowie dazwischen auf kegeligen oder rillenförmigen Laufbahnen abrollenden Wälzkörpern, einem den Lageraußenring umgebenden, geteilten Konusring und einem mit dem Konusring zusammenwirkenden, thermischen Ausgleichselement der Eingangs erwähnten Art vorgeschlagen, dass erfindungsgemäß der Konusring axial verschiebbar ist, sich über wenigstens den überwiegenden Teil der axialen Ausdehnung des Lageraußenrings erstreckt, mit seiner konischen Innenfläche eine konische Außenfläche des Lageraußenrings übergreift sowie an dieser anliegt, und dass das thermische Ausgleichselement zwischen einem Absatz eines das Wälzlager aufnehmenden Bauelements und der größeren Stirnfläche des Konusrings angeordnet ist und diesen nur axial beaufschlagt.To solve this problem is in a rolling bearing for receiving axial and radial loads, consisting of a bearing inner ring and a bearing outer ring and rolling therebetween on tapered or grooved raceways rolling elements, a bearing outer ring surrounding, split cone ring and a cooperating with the cone ring, thermal compensation element The aforementioned type suggested that the cone ring according to the invention is axially displaceable, extending over at least the major part of the axial extent of the bearing outer ring, with its conical inner surface engages over a conical outer surface of the bearing outer ring and rests against this, and that the thermal compensation element between a paragraph of the rolling bearing receiving component and the larger end face of the cone ring is arranged and this applied only axially.
Die Erfindung geht von der Überlegung aus, dass durch die axiale Kraftbeaufschlagung des geteilten Konusrings, der in Radialrichtung leicht verformbar ist, nicht nur ein Ausgleich von thermischen Axialdehnungen, sondern auch von thermischen Radialdehnungen erreicht wird. Dabei kann die Lagervorspannung in Axial- und Radialrichtung im Wesentlichen konstant gehalten werden, ohne dass an dem Wälzlager selbst wesentliche, konstruktive Änderungen vorgenommen werden müssen, und ohne dass eine große Anzahl zusätzlicher Bauteile erforderlich ist.The invention is based on the consideration that by the axial application of force to the split cone ring, which is easily deformed in the radial direction, not only a balance of thermal Axialdehnungen, but also of thermal radial expansions is achieved. In this case, the bearing preload can be kept substantially constant in the axial and radial directions, without significant, constructive changes must be made to the rolling bearing itself, and without a large number of additional components is required.
Diese Erfindung lässt sich bei allen Wälzlagern zur Aufnahme von Axial- und Radialbelastungen einsetzen, insbesondere bei Schrägkugellagern, Schrägkugelrollenlagern und Kegelrollenlagern. Bei Kegelrollenlagern kann die konische Außenfläche des Lageraußenrings parallel zu einer konischen Laufbahn des Lageraußenrings oder unter einem Winkel zur konischen Laufbahn des Lageraußenrings verlaufen.This invention can be used in all rolling bearings to accommodate axial and radial loads, especially in angular contact ball bearings, angular contact roller bearings and tapered roller bearings. In tapered roller bearings, the conical outer surface of the bearing outer race may be parallel to a tapered raceway of the bearing outer race or at an angle to the tapered raceway of the bearing outer race.
Vorzugsweise sind die Kegelwinkel der zusammenwirkenden Konusflächen des Konusrings und des Lageraußenrings so groß gewählt, dass sie axial nicht selbsthemmend sind, so dass sich der geteilte Konusring aufgrund seiner Elastizität auf dem Lageraußenring axial bewegen kann, wenn sich das thermische Ausgleichselement bei Temperaturrückgang zusammenzieht.Preferably, the cone angles of the cooperating conical surfaces of the cone ring and the bearing outer ring are chosen so large that they are not axially self-locking, so that the split cone ring can move axially due to its elasticity on the bearing outer ring when the thermal compensation element contracts at temperature drop.
