Title
(EN) RETENTION SYSTEM FOR BOLTLESS CUTTING EDGES
(FR) SYSTÈME DE RETENUE POUR DES BORDS DE COUPE SANS BOULON
Abstract
(EN) A retaining system (102b) includes a lock (300a) including a drive portion (302), that defines an axis of rotation (210a), a radial direction (750), and a circumferential direction (752), and further includes a locking portion (306a) including an outer peripheral surface (324). A wing (320) extends radially outwardly from the outer peripheral surface (324), while the locking portion (306a) is connected to the drive portion (302) by a wall (322). A rib (328) extends axially from the wall (322) toward the drive portion (302) forming an annular cavity (312), defining at least one detent receiving aperture (314) that is disposed in the annular cavity (312).
(FR) Système de retenue (102b) comprenant un verrou (300a) comprenant une partie d'entraînement (302), qui définit un axe de rotation (210a), une direction radiale (750) et une direction circonférentielle (752), et comprenant en outre une partie de verrouillage (306a) comprenant une surface périphérique externe (324). Une aile (320) s'étend radialement vers l'extérieur à partir de la surface périphérique externe (324), tandis que la partie de verrouillage (306a) est reliée à la partie d'entraînement (302) par une paroi (322). Une nervure (328) s'étend axialement à partir de la paroi (322) vers la partie d'entraînement (302) formant une cavité annulaire (312), ce qui définit au moins une ouverture de réception de cran (314) qui est disposée dans la cavité annulaire (312).
