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.

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).

Abstract: An accessory gearbox for turbomachine equipment comprising a casing (30) and two gear lines (40a, 40b) arranged in a “V” shape, the casing (30) comprising two arms (30a, 30b) in both of which one of the two gear lines (40a, 40b) is arranged, with a lubricant tank (35) being arranged between the two gear lines (40a, 40b).

Abstract: An accessory gearbox for a turbomachine, the gearbox being equipped with a pump and including intermeshing pinions, one of which is formed as a single piece with a coaxial shank for driving a rotary part of the pump, wherein said rotary part is directly mounted on the shank.

Abstract: A gearbox for the driving of auxiliaries for an aircraft turbomachine and which includes a first bevel pinion and a first bevel gear wheel forming an angle gear, the first bevel gear wheel being connected to a main shaft secured to one or more bevel pinions capable of driving one or more auxiliaries in rotation via one or more bevel gear wheels.

Abstract: An aircraft drive chain including a plurality of main pinions meshing with each other, a first main pinion including a wall delimiting an inner volume, external teeth being provided on an outer surface of the wall, the external teeth meshing with at least one second main pinion, a gear system being incorporated in the inner volume, the first main pinion and the gear system being jointly configured to form a multiplier or reducer and to ensure a mechanical energy transfer between a driving member and a slave member.

Abstract: An aircraft drive chain including a plurality of main gears engaging with each other, a first main gear including a wall defining an inner space, an outer set of gear teeth being placed on an outer surface of the wall, the outer set of gear teeth engaging with at least one second main gear, a gear system being built into the inner space, the first main gear and the gear system being jointly configured so as to form a gearbox or reducer and ensure mechanical power transfer between a drive member and a slave member, the gear system being mounted onto the wall with a decoupling member.

Abstract: The invention relates to an accessory gearbox (10) for a turbomachine, said gearbox being equipped with an air/oil separator (12) and comprising a casing (24) in which intermeshing pinions are mounted, one (18) of which is solidly connected to a coaxial shank (22) for driving at least one membrane filter (35) of the separator, characterised in that the membrane filter is mounted directly on a web of the pinion (18) inside the casing.

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.

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.
