Abstract

L'invention concerne un dispositif de blocage de la tige d'un actionneur hydraulique. Le dispositif comporte une bague de blocage 11 radialement contractable, ayant une surface intérieure cylindrique pour serrer la tige 4 lorsque la bague de blocage est contractée et une surface extérieure inclinée, des moyens 10 pour immobiliser la bague de blocage dans une position axialement fixe dans au moins une direction par rapport au corps 1 de l'actionneur, un organe 12 de serrage de la bague qui est disposé autour de la bague de blocage 11 et qui comporte une surface intérieure inclinée destinée à coopérer avec la surface inclinée de la bague et des moyens 26, 9 pour appliquer une force axiale à l'organe de serrage 12 afin de provoquer son coulissement axial sur la bague et le serrage de la tige 4 par cette dernière. Application à la fabrication des actionneurs hydrauliques.The invention relates to a device for locking the rod of a hydraulic actuator. The device comprises a radially contractable locking ring 11, having a cylindrical inner surface for clamping the rod 4 when the locking ring is contracted and an inclined outer surface, means 10 for immobilizing the locking ring in an axially fixed position in the middle. at least one direction with respect to the body 1 of the actuator, a ring clamping member 12 which is disposed around the locking ring 11 and which has an inclined inner surface intended to cooperate with the inclined surface of the ring and means 26, 9 for applying an axial force to the clamping member 12 in order to cause its axial sliding on the ring and the clamping of the rod 4 by the latter. Application to the manufacture of hydraulic actuators.
