  • Publication number: 20170009660
    Abstract: A gearbox to be attached to a turbine engine to drive at least one apparatus annexed to the turbine engine, the gearbox including a housing; a power take-off member capable of engaging with a radial shaft of the turbine engine; at least one kinematic chain located inside the housing and capable of transmitting the rotational movement of the power take-off member to at least one rotatable shaft of an apparatus. The kinematic chain includes a first end and a second end. The power take-off member is linked to the kinematic chain by a gear having convergent axes and located between the first end and the second end of the kinematic chain.

  • Publication number: 20160333793
    Abstract: The invention relates to an accessory gearbox assembly for an aircraft turbine engine including: —a radial drive shaft (41); —an input gearbox (20) including an input gear, attachable onto a drive shaft (12) connecting a turbine (11) to a compressor (10) of the turbine engine, and an output gear secured to the radial drive shaft (41); —an accessory (51) including a stator, attachable to a housing (2) of the turbine engine, and a rotor that is rotatably mounted relative to the stator; and —a transfer gearbox (41) including an input gear, rotatably secured to the radial drive shaft (41), and an output gear rotatably secured to the rotor of the accessory (51). The input gear (45) engages with the output gear (46) so that, when the drive shaft (12) is rotated, the drive shaft rotates the rotor of the accessory (51) via the input gearbox (20), the radial drive shaft (41), and the transfer gearbox (41).

  • Patent number: 9316158
    Abstract: This gearbox to be assembled to a turbomachine portion and driven by a power take-off radial shaft thereof, includes several branches, the essential advantage of which is to allow a great amount of pieces of equipment to be driven to be accommodated, without implying a significant overall size in any dimension, since the gearbox remains close to the turbomachine and the pieces of equipment can be distributed on a large surface area. The housing (5) is divided into portions (27, 28) assembled to each other at the bends, in order to reduce its manufacturing cost.

  • Publication number: 20150204246
    Abstract: This A gearbox to be mounted on a turbomachine and driven by a radial drive shaft of the latter. The gearbox has a three-dimensional or sinuous shape, which can house a large quantity of equipment to be driven, without occupying a large amount of space in any dimension, since the gearbox remains close to the turbomachine and the equipment can be distributed over a large surface. The drive train of gears successively extends into several non-parallel planes and comprises an axial branch on the turbomachine and a branch forming an arc of circle around the turbomachine.
