Abstract

Die Erfindung betrifft ein Wälzlager, welches aus einem äußeren Lagerring und einem inneren Lagerring (3) sowie aus einer Anzahl zwischen den Lagerringen durch einen Lagerkäfig (4) in Umfangsrichtung in gleichmäßigen Abständen zueinander gehaltenen Rollen (5) besteht. Die Innenseite des äußeren Lagerrings und die Außenseite des inneren Lagerrings (3) sind dabei als Laufbahnen (7) für die Rollen (5) ausgebildet, wobei die Laufbahn/Laufbahnen (7) des inneren Lagerrings (3) zumindest einseitig durch einen Führungsbord (9) begrenzt wird/werden. Die Rollen (5) weisen zwischen einem Übergangsradius (10) von ihrer Rollfläche (11) zu zumindest einer ihrer Stirnflächen (12) einen abgerundeten Bereich (13) auf, mit dem sie an einer ebenen Seitenfläche (14) des Führungsbordes (9) am inneren Lagerring (3) anlaufen. DOLLAR A Erfindungsgemäß weist der abgerundete Bereich (13) an der Stirnfläche (12) jeder Rolle (5) eine Toruskontur mit einem Radius (r) auf, dessen Mittelpunkt (M) jenseits der Längssymmetrieachse der Rolle (5) sowie außerhalb der Längsquerschnittsfläche der Rolle (5) angeordnet ist.
