Abstract

Un patin de guidage pour un anneau de transmission d’un système de commande de vannes de décharge d’une turbomachine comprenant un corps principal (6) comportant une surface de contact (60) qui est incurvée et destinée à venir en contact avec l’anneau de transmission (3), un revêtement positionné sur la surface de contact (60), la surface de contact (60) possédant un relief principal (61), le revêtement comportant un relief auxiliaire de forme complémentaire au relief principal (61), le relief principal (61) possédant une forme configurée pour opposer au moins une résistance au déplacement circonférentiel du revêtement par rapport à la surface de contact (60). Figure de l’abrégé : Figure 4A guide shoe for a transmission ring of a wastegate control system of a turbomachine comprising: a main body (6) comprising a contact surface (60) which is curved and intended to come into contact with the transmission ring (3), a coating positioned on the contact surface (60), the contact surface (60) having a main relief (61), the coating comprising an auxiliary relief of a shape complementary to the main relief (61), the main relief (61) having a shape configured to oppose at least one resistance to the circumferential movement of the coating relative to the contact surface (60).
