KUGELFIüCHER GEORG SCHÄFER & CO., 872 Schweinfurt Mehrreihiges Pendelrollenlager KUGELFIüCHER GEORG SCHAEFER & CO., 872 Schweinfurt Multi- row spherical roller bearing

Die Erfindung betrifft mehrreihige, insbesondere dreireihige Pendelrollenlager.The invention relates to multi-row, in particular three-row, spherical roller bearings.

Es sind dreireihige Pendelrollenlager bekannt, deren Außenringe jeweils ei..· kugelig gewölbte Innenfläche mit einem xür alle drei Rollenreihen gleichen Krümmungsradius aufweisen. Diese Lager ermöglichen zwar eine einwandfreie Pendelbewegung, jedoch ist die Bauhöhe verhältnismäßig groß. Es ist abe.· ; :"t erforderlich, die Bauhöhe derartiger Lager bei hoher Tragzahl εj klein wie möglich zu halten, um Gewicht und Platzbedarf so gering wie möglich sein zu lassen.Three-row spherical roller bearings are known, the outer rings of which each have an ... · spherically curved inner surface with a x for all three rows of rollers have the same radius of curvature. These bearings allow a perfect pendulum movement, but the Relatively large overall height. It's abe. ·; : "t required the overall height such bearings at a high load rating εj as small as possible to keep the weight and space requirements as low as possible.

Aufgabe der Erfindung ist es demgemäß, diese Nachteile zu vermeiden unü mehrreihige, insbesondere dreireihige Pendelrollenlager zu vermitteln, welche bei gleicher oder sogar vermindeter Bauhöhe eine erhöhte Tragzahl aufweisen, ohne daß die Betriebssicherheit beeinträchtigt oder die Bauweise aufwendiger ist.The object of the invention is accordingly to avoid these disadvantages unü multi-row, in particular three-row spherical roller bearings to convey, which have an increased load rating with the same or even reduced overall height without affecting the operational safety impaired or the construction is more complex.

Dies ist mit einem mehrreihigen, insbesondere dreireihigen Pendelrollenlager erreicht, das erfindungsgemäß dadurch gekennzeichnet ist, daß im Außenring die Krümmungsradien der Laufbahnen für die äußeren Rollenreihen jeweils größer sind als der Krümmungsradius der Laufbahn für die mittlere Rollenreihe. Dies ermöglicht die Verwendung größerer Rollen in den äußeren Reihen und hat damit eine Erhöhung der Tragzahl zur Folge, ohne daß die Bauhöhe vergrößert wer-This is achieved with a multi-row, in particular three-row spherical roller bearing, which is characterized according to the invention is that in the outer ring the radii of curvature of the raceways for the outer rows of rollers are each greater than the radius of curvature of the Track for the middle row of roles. This allows the use of larger rollers in the outer rows and thus has an increase the load rating without increasing the overall height

den muß. Außerdem ist die erwünschte maximale Ausnutzung des Außenringquerschnittes gewährleistet. Durch die Vergrößerung der äußeren Rollen wird weiterhin zwischen dem Außenring und dem Borddurchmesser des Innenringes ein größerer Zwischenraum geschaffen, was den Einbau eines größeren und stabileren Käfigs ermöglicht.the must. In addition, the desired maximum utilization of the outer ring cross-section is guaranteed. By enlarging of the outer rollers, there is still a larger gap between the outer ring and the flange diameter of the inner ring created, which allows the installation of a larger and more stable cage.

Nachstehend ist eine Ausiührungsform der Erfindung anhand der beigefügten Zeichnung beispielsweise beschrieben, deren einzige Fig. die Ansicht der oberen Hälfte eines Axial-Echnittes durch ein erfindungsgemäßes Pendelrollenlager zeigt.The following is an embodiment of the invention For example, described with reference to the accompanying drawing, the single figure of which is the view of the upper half of an axial section shows by a spherical roller bearing according to the invention.

Das dreireihige Pendelrollenlager besitzt einen Außenring 1, dessen Laufbahnen 2 und 3 für die äußeren Rollenreihen k und 5 jeweils einen größeren Krümmungsradius aufweisen als die Laufbahn für die mittlere Rollenreihe 7· Die Laufbahnen im Außenring der bekannten Konstruktionen sind durch die gestrichelte Linie angedeutet. Sie zeigt, daß bei den bekannten Lagern die Durchmesser der Rollen der äußeren Reihen kleiner sind, als die Durchmesser der äußeren Rollen k, 5 des erfinaungsgemäßen Pendelrollenlagers, weswegen die bekannten Lager gegenüber dem erfindungsgemäßen Lager bei gleicher Bauhöhe eine geringere Tragzahl aufweisen.The three-row spherical roller bearing has an outer ring 1 whose raceways 2 and 3 for the outer roller rows k and 5 each have a larger radius of curvature than the raceway for the middle roller row 7. The raceways in the outer ring of the known designs are indicated by the dashed line. It shows that in the known bearings the diameter of the rollers in the outer rows are smaller than the diameter of the outer rollers k, 5 of the spherical roller bearing according to the invention, which is why the known bearings have a lower load rating than the bearing according to the invention with the same overall height.
