Title (EN) A COUPLING AND METHOD OF MAKING THE SAME
(FR) ACCOUPLEMENT ET PROCEDE DE REALISATION
Abstract:
(EN) A shaft (12) is connected to a disc (20) by a coupling which comprises a spigot (14) which extends from the shaft (12) and locates in a recess (22) in the disc (20). At ambient temperature there is an interference fit between the spigot (14) and the recess (22) which maintains alignment of the disc (20) and the shaft (12) so that they rotate concentrically. At elevated temperatures the interference fit loosens and alignment of the disc (20) and the shaft (12) is maintained by a plurality of ridges (27) on the face (25) of a flange (24) on the disc (20). The ridges (27) have a large radial component and engage with the confronting face (17) of a flange (16) on the shaft (12) to prevent lateral movement between the shaft (12) and the disc (20).
(FR) Un arbre (12) est relié à un disque (20) par un accouplement qui comprend une partie saillante (14) s'étendant depuis l'arbre (12) et se logeant dans un évidement prévu dans ledit disque (20). A température ambiante il existe un ajustement serré entre la partie saillante (14) et l'évidement (22), ce qui assure l'alignement du disque (20) et de l'arbre (12) et leur permet ainsi de tourner de manière concentrique. A température élevée l'ajustement devient moins serré et l'alignement du disque (20) et de l'arbre (12) est assuré par une pluralité de nervures (27) dont est dotée la face (25) d'une bride (24) du disque (20). Les nervures (27) ont une composante radiale importante et prennent appui sur la face correspondante (17) d'une bride (16) de l'arbre (12) pour prévenir tout mouvement latéral entre l'arbre (12) et le disque (20).
