FIELD: engines and pumps.
SUBSTANCE: proposed mechanism comprise two opposite rotation propellers, drive turbine, shaft engaged therewith, fixed casing supporting the turbine by shaft and two bearings, transmission and hub. Transmission comprises planetary gearing with central planetary gear drive by turbine, pinion carrier equipped with plane pinions engaged with planetary gears and outer rim to be engaged with plane pinions. Pinion carrier drives of the propellers while outer rim drives the second propellers. The bush is engaged with turbine and planetary gear and is surrounded by said shaft. Note here that clearance is maintained between said bush and shaft. Bush features larger elasticity than the shaft so that it bends when unbalances forces are applied to planetary gear in radial direction. Spacing between one of the bearings and planetary gear is the spacing between two bearings.
EFFECT: lower mechanical strain in gearing, higher reliability.
