Abstract RU 2095278 C1

FIELD: water transport; controllable-pitch propellers. SUBSTANCE: blade-pitch control mechanism is provided with holder which is movable along axis of propeller shaft. Holder embracing the propeller shaft is provided with inner circumferential groove engageable with eccentric pins of differential satellite axles. Differential gear is kinematically closed by gear rim of propeller shaft turning tubular control shaft embracing the propeller shaft. Rotation of control shaft makes gear rims on blade shanks turn, thus changing their pitch. EFFECT: enhanced hydrodynamic efficiency; simplified construction; maintainability and ecological safety. 1 dwg
