Abstract

La présente invention concerne un dispositif de guidage de roulement, pour lequel le montage d'un bloc mobile sur une glissière et son retrait de cette dernière sont simples, pourvu : d'une glissière (2, 302) possédant une surface de roulement destiné à un corps roulant (1) formée sur celle-ci dans la direction axiale; et d'un bloc mobile (3, 303) destiné à guider un corps mobile (10) le long de la direction axiale de la glissière (2, 302), possédant une pluralité de circuits illimités de corps roulant (1), et fixé à la glissière (2, 302) par une pluralité de corps roulants (1). En outre, le bloc mobile (3, 303) est pourvu : d'une paire de corps séparés (4) qui comportent chacun une surface de fixation (42) de corps mobile et un circuit illimité; et d'un mécanisme d'articulation (6, 306) destiné à fixer en rotation les deux corps séparés (4) l'un à l'autre et ayant un axe de rotation qui est parallèle à la direction axiale de la glissière (2, 302). Il est possible de monter le bloc mobile (3, 303) à la glissière (2, 302) et de le retirer de cette dernière par la rotation de chacun des corps séparés (4) à l'aide du mécanisme d'articulation (6, 306) comme centre de rotation.
