FIELD: engines and pumps.
SUBSTANCE: accessory gearbox for actuation of aircraft gas turbine engine units includes housing and multiple gear wheels inside housing. Housing comprises means for attachment of units on housing wall and for their actuation by gear wheels through holes in housing wall. Wheels are installed in the housing on rolling bearings, at that each bearing contains the first ring fixed relative to the housing, and movable ring rigidly connected with the wheel. One of gear wheels is installed only on one rolling bearing, fixed ring of which is radially internal and installed on axis, rigidly connected with housing wall. Another invention relates to gas turbine engine equipped with above described accessory gearbox.
EFFECT: group of inventions allows reducing sizes of accessory gearbox of gas turbine engine units.
