Abstract:
(DE) Die Erfindung betrifft einen Wälzlagerkäfig, umfassend mehrere Käfigsegmente, die jeweils zwei im Wesentlichen gegenüberliegende Kontaktflächen zum Kontaktieren benachbarter Käfigsegmente aufweisen, dadurch gekennzeichnet, dass bei einer Aneinanderreihung der Käfigsegmente in einer Art wie die Käfigsegmente in einem Wälzlager angeordnet sind, zwischen den Kontaktflächen der Käfigsegmente ein oder mehrere Spalte entstehen, wobei jeder Spalt eine kleinste prozentuale Spaltbreite aufweist, die dem kleinsten Wert der Entfernung von zwei den Spalt benachbarten Kontaktflächen auf einem zum Wälzlagerkäfig konzentrisch angeordneten Kreis bezogen auf den Umfang dieses Kreises entspricht, und wobei die Summe aller prozentualer Spaltbreiten bei Raumtemperatur größer als 1,0 % ist.
(EN) The invention relates to a rolling bearing cage, comprising a plurality of cage segments, which each have two substantially opposed contact surfaces for contacting adjoining cage segments, characterized in that when, stringing the cage segments to each other in a manner in which the cage segments are arranged in a rolling bearing, one or more gaps are formed between the contact surfaces of the cage segments, wherein each gap has the smallest gap width in percent, which corresponds to the smallest value of the distance of two contact surfaces adjoining the gap on a circle arranged concentrically to the rolling bearing cage, with respect to the circumference of said circle, and wherein the sum of all gap widths in percent is greater than 1.0% at room temperature.
(FR) L'invention concerne une cage de roulement comprenant plusieurs segments de cage qui présentent respectivement deux surfaces de contact pratiquement opposées pour la mise en contact de segments de cage voisins. La cage de roulement selon l'invention est caractérisée en ce que, lors de la juxtaposition des segments de cage à la manière dont ils sont placés dans un palier à roulement, un ou plusieurs interstices se forment entre les surfaces de contact des segments de cage. Chaque interstice a une largeur minimale en pourcentage qui correspond à la plus petite valeur de la distance entre deux surfaces de contact adjacentes à l'interstice sur un cercle concentrique à la cage de roulement par rapport à la circonférence de ce cercle, la somme de toutes les largeurs d'interstice en pourcentage étant supérieure à 1,0 % à température ambiante.
