SELF-LOCKING MECHANISM

A self-locking mechanism has a drive member (52), a driven member (54), a stationary member (80), a locking bracket (56) and a plurality of locking elements (564). The locking bracket houses the driving member and the driven member. The locking bracket has a support base (562) and ribs (563) extendi...

Zusammenfassung:A self-locking mechanism has a drive member (52), a driven member (54), a stationary member (80), a locking bracket (56) and a plurality of locking elements (564). The locking bracket houses the driving member and the driven member. The locking bracket has a support base (562) and ribs (563) extending from the support base. A locking member (564) is connected to the axial end portion of each rib (563). The locking elements are positioned radially between a radially outer surface of the driven member (54) and the inner wall of the stationary member (80). The distance between the radially outer surface and the inner wall decreases from a central portion to opposing circumferential sides gradually decreases. The maximum distance between the radially outer surface and the inner wall is greater than the diameter of the locking element, and the minimum distance is smaller than the diameter of the locking element. Un mecanismo de auto-cierre tiene un miembro de impulsión, un miembro impulsado, un miembro de cierre. El soporte de cierre tiene una base de soporte y costillas que se extienden desde la base de soporte. Un elemento de cierre está acoplado a la parte de extremo axial de cada costilla. Los elementos de cierre están colocados radialmente entre una superficie que se extiende radialmente exterior del miembro impulsado y la pared interior del miembro estacionario. La distancia entre la superficie radialmente exterior y la pared interior gradualmente disminuye desde un centro a los lados circunferenciales opuestos. La distancia máxima entre la superficie radialmente exterior y la pared interior es mayor que el diámetro del elemento de cierre y la distancia mínima es menor que el diámetro del elemento de cierre.
