Abstract

Dispositif permettant d'assurer à la fois un appui et un guidage d'une crémaillère. Il comprend une tige-guide traversant de part en part l'axe longitudinal de la crémaillère Liée au piston d'un actionneur hydraulique ou pneumatique, cette tige assure le guidage du piston et sert à assembler les différentes pièces de l'ensembe ainsi constitué sans autre pièce. L'invention peut être utilisée dans les éléments de machines utilisant le système << crémaillère-pignon >> et dans les actionneurs angulaires à commande hydraulique ou pneumatique.
