Abstract

On connaît les joints homocinétiques conçus sous la forme de joints tripodes. Les joints tripodes de ce type présentent, en tant que premier élément de joint, une extrémité d'arbre sur laquelle sont formées des parties pivot en saillie radialement vers l'extrémité d'arbre, sur lesquelles sont agencés des galets. Ce premier élément de joint est introduit dans une cloche, les galets pouvant rouler sur une face intérieure de la cloche, de sorte que l'extrémité d'arbre pivote par rapport à la cloche mais peut tourner conjointement avec la cloche. L'invention vise à simplifier la fabrication de joints tripodes. À cet effet, le galet de roulement (9) pour joint coulissant (1) selon l'invention présente un dispositif de bague intérieure (11) logeant un pivot (8) d'une partie bout d'arbre (7), un dispositif de bague extérieure (12), un chemin de roulement (15) étant ménagé sur la face extérieure du dispositif de bague extérieure (12) pour le roulement sur une partie cloche (10), une pluralité d'éléments roulants (17), les éléments roulants (17) étant agencés entre le dispositif de bague intérieure (11) et le dispositif de bague extérieure (12), un dispositif de cage (18), les éléments roulants (17) étant agencés dans le dispositif de cage (18), le dispositif de cage (18) présentant au moins un point de séparation (28) dans la direction périphérique.
