FIELD: engines and pumps.
SUBSTANCE: rotor drive of auxiliary unit, which is installed on support of units of gas-turbine engine, which contains rotor shaft drive means, includes tubular shaft rotated with the above means and supported with the first and the second support bearings rigidly connected to the support of the units. Rotor shaft is installed coaxially with tubular shaft, and engagement device with rotation is provided between rotor shaft and tubular shaft. Rotor shaft is supported with the third support bearing rigidly connected to the support of the units. The first and the second support bearings have the size which is less than size of the third support bearing. The other invention of the group refers to the support of gas-turbine engine units, which contains the gears rotating the above drive. One more invention of the group refers to gas-turbine engine containing the shaft and power take-off devices on the shaft, rotary gears of the above support of the units.
EFFECT: inventions allow improving reliability of rotor drive of auxiliary unit.
