Abstract

Ce palier est équipé d'un circuit de lubrification dont le fonctionnement est indépendant de la gravité. Un disque de feutre 20 formant réservoir dépose de l'huile sur la petite extrémité d'un manchon conique 18 porté par l'arbre. Dans la rotation, l'huile s'écoule sous l'effet de la force centrifuge sur la surface du manchon pour passer sur les billes du roulement 12. L'huile atteint ensuite un rotor 22 monté sur l'arbre qui projette l'huile sur une bague collectrice 24, puis revient au servoir 20 par des mèches 25. Le rotor porte des pales de ventilateur 23 qui aspirent, à travers le roulement 12, l'air chargé de gouttelettes de lubrifiant projetées par le manchon 18 puis le refoulent dans la chambre adjacente au réservoir à travers des perçages 27. Ce palier est notamment applicable aux petits moteurs (de l'ordre de 1 000 watts) tournant à grande vitesse (par exemple 20 000 tr/mn) notamment aux moteurs de ventilateurs qui doivent travailler dans des attitudes très variables et éventuellement en apesanteur.
