Embodiment Construction

[0026] The invention is described in relation to a turbojet engine. The turbojet generally includes a high-pressure shaft and a low-pressure shaft, each shaft including a compressor and a turbine. An energy distribution mechanism is mounted on said high pressure shaft and drives an energy distribution shaft which is mechanically connected to an auxiliary gearbox 1 , hereinafter denoted by the English abbreviation AGB 1 . More specifically, the energy distribution shaft transmits movement from the rotational axis of the high pressure shaft to the input (or drive) shaft of the AGB 1 . The input shaft of the AGB 1 is fixed to the wall of the AGB by a connection (in this case to the figure 1 The piece 11 of the upper wall) is connected to the AGB 1. The input shaft, supported by the connection 11 , passes through the upper wall of the AGB 1 in a conventional manner.

[0027] The turbojet engine also includes a lubricating circuit comprising an oil reservoir 2, a lubricating uni...

Abstract

An assembly that includes an accessory gearbox (AGB) and a tank for a liquid lubricant for a turbojet engine. The AGB includes a gear connected to parallel shafts for mechanically driving accessories. The assembly includes a housing with two compartments and a partition perpendicular to the shafts for separating the compartments, a compartment defining the accessory gearbox and a compartment defining the liquid tank. The assembly can be compact and easily manufactured.

Description

technical field [0001] The invention relates to an assembly comprising an attachment gearbox and a lubricating oil reservoir for a turbojet engine. Background technique [0002] A turbojet engine includes, from upstream to downstream in the direction of air flow: a fan, one or more compressor stages (such as a high-pressure compressor), a combustion chamber, one or more turbine stages (such as a high-pressure turbine and a low-pressure turbine), and a nozzle, Air is discharged through the nozzle. Each compressor has a corresponding turbine, which are connected by a shaft, forming eg a high pressure spool and a low pressure spool. [0003] A part of the energy generated by the turbojet is used to power the various accessories of the turbojet. This energy is split off mechanically from the shaft of the turbojet's high-pressure shaft through a split shaft, which drives the input shaft of the gearbox of the auxiliary equipment. [0004] The English abbreviation AGB of the acc...
