A device for mounting a ring gear of an epicyclic gear train, the ring gear including a front ring gear and a rear ring gear, the device including: a plurality of longitudinal guides; a front mounting forming a portion of circle, including: at least two holes for passing the guides; a plurality of first system for supporting and rotating the front ring gear relative to the axis thereof, movable between a first position in which the front ring gear is supported and can rotate relative to the axis thereof and a second position in which the front ring gear is not supported; a rear mounting forming a portion of circle, including: at least two holes for passing the guides; and a plurality of second system for supporting and rotating the rear ring gear relative to the axis thereof, movable between a third position in which the rear ring gear is supported and can rotate relative to the axis thereof and a fourth position in which the rear ring gear is not supported.

Device to install a ring of a planetary gear train

A method for aligning toothing in an assembly of two half-ring gears is provided:

Ring gear for an epicyclic reduction gear

A wheel for distributing a lubricant in a turbine engine has an axis from which an annular cavity extends, open radially towards the axis and from which first and second lubricant supply lines depart for various members to be lubricated. Parallel to the axis, the annular cavity is split into at least a first and a second annular sub-cavity, which are separated by a substantially radial partition and which communicate with the first and second lines respectively.

Axially-partitioned oil-distribution wheel, and planetary reduction gear comprising such a wheel

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.

Compact structure for accessory gearbox of an aircraft turbine engine

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.

Incorporation of a gear train in a pinion wall in a gearbox for a turbomachine

An accessory gearbox for turbomachine equipment comprising a casing () and two gear lines () arranged in a 'V' shape, the casing () comprising two arms () in both of which one of the two gear lines () is arranged, with a lubricant tank () being arranged between the two gear lines ().

Accessory gearbox

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

Turbomachine accessory gearbox equipped with an air/oil separator

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.

Drive gearbox on a turbomachine, consisting of a drive train with gear lines extending into non-parallel planes

An epicyclic reduction gear, for example for a turbomachine, including a device forming a fluid circulation passage configured to generate a pressure drop, created by stacking at least two elements. Each element includes a passage for carrying fluid configured to generate a pressure drop and including an inlet and an outlet. The outlet, or inlet, of the passage of one of the elements is, respectively, connected to the inlet, or to the outlet, of the passage of the other element.

Epicyclic reduction gear, notably for turbomachine

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 () is divided into portions () assembled to each other at the bends, in order to reduce its manufacturing cost.
