BENCH-TYPE REDUCTION GEAR UNIT FOR TESTING OF ENGINES Russian patent published in 2014 - IPC G01M15/14 

FIELD: engines and pumps.

SUBSTANCE: low-speed shaft of a reduction gear unit, which is passed coaxially by means of a coupling of an alternating connection to it through a gear wheel of the first stage, which is engaged with a gear of a high-speed shaft, and is rigidly connected to a gear of a solar type in the second planetary stage with an epicycle with a brake device, with satellite gears installed with possibility of being rotated on axes reinforced in a carrier installed with possibility of being rotated; the above carrier has a possibility of an alternating connection by means of a coupling with a low-speed shaft and connected on the side opposite to arrangement of engines with a shaft of a loading device. A possibility of an alternating connection of power shafts of engines with different ranges of revolutions and powers by means of connecting couplings to outlet ends of high-speed or low-speed shafts is provided.

EFFECT: improving reliability, optimising and simplifying testing conditions of engines of different types, namely of marine gas-turbine and diesel engines by using a two-shaft bench-type reduction gear unit with a loading device, which allows alternating test of engines with three different rages of revolutions and powers.
