Abstract

L'accouplement d'arbres comprend un carter 10, un couple d'engrenages constitué par une couronne dentée et un pignon, logé dans ce carter et assurant l'entraînement entre un élément d'entrée relié à ce pignon et un élément ou plusieurs éléments de sortie reliés à cette couronne dentée, des paliers portés par une partie du carter et retenant ledit élément d'entrée et ce pignon et une certaine quantité de lubrifiant liquide contenue dans ledit carter 10. Il est prévu, dans le carter 10, deux passages 21, 22 présentant chacun une entrée munie d'une saillie 25, 26 située tout près du pourtour d'un élément rotatif 28 d'entraînement de lubrifiant, servant à retirer du lubrifiant d'une pellicule de lubrifiant entraînée par cet élément sous l'effet de sa rotation, et à envoyer ce lubrifiant dans le passage 21, 22, ces saillies 25, 26 agissant chacune dans l'un des deux sens opposés de rotation dudit élément et lesdits passages 21, 22 assurant l'envoi de lubrifiant dans les paliers de l'élément d'entrée. Application notamment aux accouplements d'arbres comportant un différentiel.The shaft coupling comprises a casing 10, a pair of gears constituted by a toothed ring gear and a pinion, housed in this casing and ensuring the drive between an input element connected to this pinion and one element or several elements. output connected to this toothed ring, bearings carried by a part of the housing and retaining said input element and this pinion and a certain quantity of liquid lubricant contained in said housing 10. There are provided, in the housing 10, two passages 21, 22 each having an inlet with a protrusion 25, 26 located very close to the periphery of a rotary lubricant drive member 28, for removing lubricant from a film of lubricant entrained by this member below the shaft. effect of its rotation, and in sending this lubricant into the passage 21, 22, these projections 25, 26 each acting in one of the two opposite directions of rotation of said element and said passages 21, 22 ensuring the delivery of lubricant in the element bearings entry. Application in particular to shaft couplings comprising a differential.
