Abstract

La présente invention concerne une liaison de rotation destinée à une machine d'actionnement et, plus précisément, une liaison de rotation destinée à une machine d'actionnement conçue pour accomplir efficacement une prévention de l'usure mécanique d'une liaison de rotation destinée à faire tourner un élément constitutif d'une machine d'actionnement telle qu'une excavatrice, une prévention du détachement d'un élément de fixation dû à une sollicitation d'un agencement d'un élément d'entraînement en rotation, et au freinage de l'élément d'entraînement en rotation. Une liaison de rotation destinée à une machine d'actionnement selon la présente invention est caractérisée en ce qu'elle consiste en : un moteur de rotation ; un engrenage d'entraînement qui reçoit une puissance de rotation générée par le moteur de rotation ; un engrenage inférieur accouplé à l'engrenage d'entraînement de façon à convertir la rotation verticale de l'engrenage d'entraînement en une rotation horizontale, une rainure de freinage étant formée sur l'engrenage inférieur ; une plaque supérieure accouplée à l'engrenage inférieur, un roulement à billes étant interposé entre ceux-ci ; et une partie freinage fixée au côté inférieur de la plaque supérieure et accouplée à la rainure de freinage de l'engrenage inférieur ou séparée de celle-ci, ce qui permet de supprimer la rotation horizontale de l'engrenage supérieur ou de l'autoriser.
