Title (EN) TORQUE-LIMITING ASSEMBLY
(FR) DISPOSITIF LIMITEUR DE COUPLE
Abstract: front page image
(EN)A torque-limiting assembly includes a collar (36), a locking ring (38), and a sleeve member (39). The collar is co-axially and rotatably coupled to a fitting. The locking ring is non-rotatably coupled to the collar, and includes a plurality of elongate tangs (46) arranged circumferentially around the ring. The sleeve member is non-rotatably and co-axially coupled to the fitting, and has a plurality of contact surfaces (54) that form an outer circumference of the sleeve member. Torque is applied to the collar by way of a plurality of substantially flat surfaces (44) disposed along an outer circumference of the collar. The torque is transferred to the locking ring by way of the fixed geometric relationship between the collar and the ring. The locking-ring tangs securely grasp the sleeve-member contact surfaces when the applied torque is below a predetermined amount, and thereby transfer a substantial entirety of the applied torque to the fitting. The tangs flex and slip along the contact surfaces when the applied torque exceeds the predetermined amount, thereby preventing torque greater than the predetermined amount from being transferred to the fitting.
(FR)L'invention concerne un dispositif limiteur de couple, comprenant un anneau (36), une bague de serrage (38) et un élément manchon (39). L'anneau est accouplé rotatif, sur le même axe, à un raccord. La bague de serrage est accouplée non rotative à l'anneau et comprend plusieurs dents allongées (46) disposées sur la circonférence autour de la bague. Le manchon est accouplé non rotatif, sur le même axe, au raccord et possède plusieurs surfaces de contact (54) qui constituent une circonférence extérieure dudit manchon. On applique un couple à l'anneau au moyen de plusieurs surfaces sensiblement plates (44) disposées le long d'une circonférence extérieure dudit anneau. On transmet ce couple à la bague de serrage grâce à la relation à géométrie fixe entre l'anneau et la bague. Lorsque le couple appliqué est inférieur à un seuil déterminé, les dents de la bague de serrage entrent en prise solidement avec les surfaces de contact du manchon et transmettent ainsi au raccord la quasi-totalité du couple appliqué. Ces dents fléchissent et glissent le long des surfaces de contact lorsque le couple appliqué dépasse une valeur déterminée, ce qui empêche de transmettre au raccord un couple supérieur à une valeur déterminée.
