Abstract

L'invention propose un agencement d’un vilebrequin dans un carter-cylindres de moteur thermique tenu par des paliers avec un coussinet de palier de vilebrequin entourant un tourillon (12) et comportant une demi-bague semi-cylindrique supérieure (30) dont la paroi concave (34) comporte un premier tronçon (42-1) de rainure circulaire qui s’étend depuis une première extrémité (38-1) de la bague semi-cylindrique, seulement le long d’une portion de la paroi concave (34), et un deuxième tronçon (42-2) de rainure circulaire qui s’étend depuis une deuxième extrémité (38-2) de la bague semi-cylindrique, seulement le long d’une portion angulaire de la paroi concave (34), qui sont séparés l’un de l’autre d’un arc de cercle d’une longueur de corde supérieure ou égale au diamètre du conduit de distribution creusé dans le vilebrequin pour relier le tourillon à un maneton. Figure pour l’abrégé : Fig. 2The invention proposes an arrangement of a crankshaft in a thermal engine cylinder block held by bearings with a crankshaft bearing bush surrounding a pin (12) and comprising an upper semi-cylindrical half-ring (30) whose concave wall (34) has a first section (42-1) of circular groove which extends from a first end (38-1) of the semi-cylindrical ring, only along a portion of the concave wall (34 ), and a second section (42-2) of circular groove which extends from a second end (38-2) of the semi-cylindrical ring, only along an angular portion of the concave wall (34), which are separated from each other by an arc of a chord length greater than or equal to the diameter of the timing duct cut into the crankshaft to connect the journal to a crank pin.
