Abstract: front page image
(EN)A separator (8) comprising a solid lubricant is placed between adjacent rolling elements (7). Relative movement of the adjacent rolling elements (7) and the separator (8) in a direction of breaking away in a circumferential direction is restricted by restricting members (10), and the restricting members (10) are placed in multiple locations in the circumferential direction. Tiny gaps (α) are provided between adjacent restricting members (10), allowing relative movement therebetween. A solid-lubrication rolling bearing is thereby provided which can stably prevent rotational locking of the bearing and unintended disassembling over a long period of time.
(FR)Selon l'invention, un séparateur (8) constitué d'un lubrifiant solide, est disposé entre des éléments roulant (7) adjacents. Les déplacements relatifs des éléments roulant (7) adjacents et du séparateur (8) dans une direction s'écartant d'une direction périphérique, sont régulés par des éléments de régulation (10) disposés en une pluralité d'endroits dans la direction périphérique. Les déplacements relatifs de ces derniers, sont cependant autorisés par agencement d'un très petit intervalle (α) entre les éléments de régulation (10) adjacents. Par conséquent, l'invention fournit un palier à roulement avec lubrifiant solide qui permet de manière stable sur le long terme d'empêcher un verrouillage de roulement ou un déblocage non intentionnel du palier.
