Abstract: An aircraft turbomachine module, including an accessory gearbox, a transfer shaft, and a drive shaft rotatably connected with one another by a power transmission device. The power transmission device can be housed in a gearbox and the module can further include an electric machine rotatably connected to the transfer shaft. The electric machine can be interposed between the transmission housing and at least one part the transfer shaft.

Abstract: The invention relates to a device for sealing an opening of an enclosure wall for access to a rotary shaft. The device is capable of being sealingly inserted in said opening and of being secured against the wall by securing elements. The device includes two cylindrical parts assembled slidably relative to one another, coaxially relative to the opening: a first part capable of being statically inserted in the opening, and a second part capable of being secured to the wall by the securing elements and subjected to the action of a resilient means provided between the parts and tending to axially separate the second part from the wall.

Abstract: A manual mechanical drive to a high pressure sub assembly of a turbojet during endoscopic inspection of the high pressure turbine is provided. A coupling element suitable for coupling with an external actuator such as a crank handle is fitted on the axis of an alternator that is normally driven mechanically via the high pressure sub assembly, thereby providing a coupling suitable for driving said high pressure sub assembly.

Abstract: A guide and sealing device a shaft in an orifice in a casing in a turbine engine, the device including a carbon gasket mounted around the shaft including a ring secured to the shaft and having an annular friction face rubbing against a carbon annulus mounted in a support bushing fastened to the casing, the ring presenting a cylindrical wall that is centered and guided in rotation in a cylindrical wall of the support bushing so as to form a smooth bearing for guiding the shaft.

Abstract: A gearbox in a turbine engine for imparting rotary drive to at least one piece of rotary equipment, the gearbox including a transmission shaft guided in rotation in bearings and carrying a toothed wheel meshing with at least one rotary drive gearwheel. One of the bearings is a rolling bearing mounted inside the toothed wheel in a radial plane containing the toothed wheel and the drive gearwheel, and another of the bearings is a smooth bearing for taking up forces tending to tilt the transmission shaft.

Abstract: Providing manual mechanical drive to the high pressure sub assembly of a turbojet, in particular during endoscopic inspection of the high pressure turbine. According to the invention, a coupling element suitable for coupling with an external actuator such as a crank handle is fitted on the axis of a specific alternator that is normally driven mechanically via the high pressure sub assembly, thereby providing a coupling suitable for driving said high pressure sub assembly.
