Abstract

La présente invention concerne un dispositif d'alimentation en huile non mécanique pour un broyeur giratoire. Le dispositif comprend un bâti (1), un moteur d'entraînement (9), un arbre principal excentrique (3), une partie cône de broyage (5) et un corps de marteau fixe, un palier étant monté à l'extérieur de l'arbre principal excentrique (3) agencé verticalement, un manchon d'arbre d'étanchéité (13) est emmanché sur un côté extérieur du palier, un canal de lubrification (12) est formé entre l'arbre principal excentrique (3) et le palier, et une extrémité inférieure du canal de lubrification (12) est reliée à une conduite (7) de sortie d'huile; et un canal d'huile est disposé dans l'arbre principal excentrique (3) de bas en haut, une extrémité supérieure du canal d'huile est reliée à une extrémité supérieure du canal de lubrification (12), une extrémité inférieure du canal d'huile est reliée à une conduite (6) d'entrée d'huile, et la conduite (6) d'entrée d'huile et la conduite (7) de sortie d'huile sont reliées à une cavité d'huile destinée à stocker de l'huile de lubrification liquide. Le dispositif constitue une alimentation automatique en huile pour une lubrification par le fonctionnement à grande vitesse d'un arbre d'entraînement de l'appareil lui-même et par l'utilisation d'un principe centrifuge, sans qu'il soit nécessaire de fournir en plus une énergie mécanique à l'huile de lubrification liquide, ce qui permet ainsi de réduire la consommation d'énergie ainsi que les coûts de fonctionnement et d'économiser de l'espace d'assemblage.
