Patent

CA 2690813

The invention relates to an axial bearing for absorbing high axial loads of a shaft having a bearing ring (7) that comprises a central bore for inserting the shaft (1) and is supported on a fixed base (9); having a plurality of spring elements (6) made of elastic material attached to the bearing ring (7); having a load transmission device (3) for transferring the load from the shaft (1) to the spring elements (6). The invention is characterized by the following features: the spring elements (6) are elastic bodies that may be joined to one another or inserted into one another like puzzle pieces in a form-fitting manner; the contours of the spring elements (6) are structured such that no gap remains between adjacent spring elements, at least beginning at a cer-tain load.

L'invention concerne un palier axial destiné à recevoir des charges axiales élevées d'un arbre, qui comprend une bague de palier (7) qui présente un alésage central à travers lequel l'arbre (1) peut passer, et qui s'appuie sur un palier inférieur fixe (9). Le palier axial présente une pluralité d'éléments de ressort (6) en matériau élastique montés sur la bague de palier (7) ; il présente aussi un dispositif de transfert de charge (3) pour transférer la charge de l'arbre (1) aux éléments de ressort (6). L'invention est caractérisée par les caractéristiques suivantes : les éléments de ressort (6) sont des corps élastiques qui peuvent être assemblés comme un puzzle par engagement par coopération de forme les uns aux autres et/ou les uns dans les autres ; les contours des éléments de ressort (6) sont configurés de telle sorte qu'il ne subsiste aucun espace entre des éléments de ressort adjacents, au moins à partir d'un certain état de sollicitation.
