FIELD: engine building.
SUBSTANCE: invention relates to gas turbine engine (GTE) accessory drive gearbox (ADG) drive design and can be used in GTE for aircraft and ground applications. In the proposed versions of the invention, in contrast to the prototype, the location of the jet for supplying oil to the gear components (GC) and the bearings of the oil leak detection device in the housing of the oil leak detection device provides unobstructed access to the inner cavities of the conical gear components. Possibility of installation of strain gauges on external surfaces of the investigated parts, including on the diaphragm or rim of the driving conical gear component, on the spline roller connecting the ADG GC and the oil leak detection device, on the spline roller connecting the conical gear components of the oil leak detection device and the center drive, on the ADG gear component, on the spline roller of the drive unit installed on the ADG, on the driven conical center drive gear component allows to carry out strain and thermometry of these parts and to measure actual values of stress and temperature.
EFFECT: higher reliability.
