Title
(EN) NUT SYSTEM AND AIRCRAFT ENGINE MOUNTING STRUCTURE COMPRISING SAME
(FR) SYSTEME D'ECROU ET MAT D'ACCROCHAGE DE MOTEUR D'AERONEF COMPRENANT UN TEL SYSTEME
Abstract
(EN)
The invention concerns a nut system (100) comprising a nut (104) provided with a main thread (106) of pitch p1 and arranged along a screwing axis (108) of the nut. The invention is characterized in that it further comprises a threaded member (116) coupled in rotation with the screw, said threaded member including a secondary thread (122) not screwed on the main thread (106) from which it is spaced apart, the secondary thread being arranged along the screwing axis and being provided with a pitch p2 different from p1. The invention is applicable to a device for absorbing thrust loads generated by an aircraft engine.
(FR)
L'invention concerne un système d'écrou (100) comprenant un écrou (104) pourvu d'un filetage principal (106) de pas p1 et agencé selon un axe de vissage (108) de l'écrou. Selon l'invention, il comporte en outre un organe fileté (116) couplé en rotation avec l'écrou, cet organe fileté comportant un filetage secondaire (122) non-vissé sur le filetage principal (106) duquel il est écarté, le filetage secondaire étant agencé selon l'axe de vissage et disposant d'un pas p2 différent de p1. Application de l'invention à un dispositif de reprise des efforts de poussée générés par un moteur d'aéronef.
