Abstract

La présente invention concerne un palier de poulie de type nouveau et son procédé de montage, un composant de poulie et un ensemble poulie. Le palier de poulie de type nouveau comprend une bague intérieure (110), une bague extérieure (120) et des éléments roulants (130). La bague intérieure (110) comprend un corps principal de bague intérieure (111), une première bride (112) et une seconde bride (113), la première bride (112) et la seconde bride (113) étant respectivement situées aux deux extrémités du corps principal de bague intérieure (111) ; plusieurs brides intermédiaires fixes (120) sont disposées sur un côté interne de la bague extérieure (120) pour disposer à distance les éléments roulants adjacents (130) ; et la première bride (112) et/ou la seconde bride (113) sont raccordées de façon détachable au corps principal de bague intérieure (111). Le corps principal de bague intérieure présente une structure non divisée intégrale sans bride intermédiaire, ce qui réduit le rainurage, le poinçonnage, le serrage d'arceau, etc., impliqués dans un processus de séparation et réduit les faces d'usinage des brides intermédiaires. De plus, la bague intérieure n'a pas de bride intermédiaire, la bague extérieure présente un grand espace de réglage de largeur de bride intermédiaire, et donc à condition que le palier de poulie ait la même dimension de contour qu'un palier existant, la longueur de l'élément roulant peut être augmentée de manière appropriée, de telle sorte que la capacité de transport de charge du palier est améliorée, et le palier de poulie présente un procédé simple et une capacité de transport de charge élevée.
