Transmission device tight between two coaxial shafts mounted in housings fixed to one another, allowing a rapid intervention, in particular in the case of a leak.

摘要

In order to reduce the time of use, in particular in the case of a leak occurs between a housing, such as a gear box (130) and a piece of equipment such as a fuel pump (134) fixed onto this casing is actuated by a turbo - machine through the housing of gears, it is proposed a transmission device tight drained and dismountable, making it possible to intervene without dismantling the equipment. This device comprises a removable cover (144) fixed on the housing (130) at the opposite end of the equipment (134), and in which is placed a drive member to be removable (154 and 162) ensuring the transmission to an input shaft (136) of the equipment of a movement of rotation of the output shaft (124) of the gear box. This drive member includes a zone (166) of lesser resistance and cooperates with a tubular extension (134c) of the housing of the equipment which projects inside the cover, by means of two sealing members (172 and 174) located on each side of said zone.
