Abstract

L'invention concerne une structure de support de palier apte à gérer une charge maximale d'urgence qui se produit rarement, et permettant d'utiliser une charge de fatigue pour déterminer la constitution du palier pendant un fonctionnement normal. L'invention concerne également une structure de support de palier pour un support en porte-à-faux rotatif de l'arbre principal (7) d'une tête de rotor (4) qui tourne autour d'une ligne d'arbres, la structure de support de palier étant pourvue d'un palier à double rangée de rouleaux coniques (10) apte à supporter indépendamment le côté extrémité avant d'une section d'arbre de la tête de rotor (4) en tant que poutre en porte-à-faux sur laquelle un moment est exercé, et un palier lisse (20) pour supporter le côté extrémité arrière d'une section d'arbre du palier à double rangée de rouleaux coniques (10). Le palier à double rangée de rouleaux coniques (10) supporte indépendamment l'arbre principal (7) pendant un fonctionnement normal lorsqu'une charge inférieure ou égale à une valeur prédéterminée est exercée, et le palier lisse (20) supporte l'arbre principal (7) en conjonction avec le palier à double rangée de rouleaux coniques (10) uniquement pendant un fonctionnement d'urgence lorsqu'une charge importante qui dépasse la valeur prédéterminée est exercée.
