FIELD: shipbuilding.
SUBSTANCE: adjustable pitch propeller contains a pitch change mechanism, a propeller shaft, a propeller hub with rotary blades, with bevel pinion gears fixed on its root parts. The pinion gears are engaged with two bevel gears coaxial with the axis of the propeller shaft - bow and stern. The pitch change mechanism is designed as a lamellar rotary hydraulic motor, which is a cylindrical body coaxial with the axis of the propeller shaft and resting with its ends on the bow and stern bevel gears, divided diametrically by a rotary plate into two not interconnected equal cavities. The cylindrical body is rigidly connected to the nose bevel gear, and the aft bevel gear is rigidly connected to the turning plate. The hydraulic system of the pitch change mechanism comprises a shunting hydraulic cylinder connected to the working cavities of the rotary vane hydraulic motor, and a power cylinder interacting with the shunting hydraulic cylinder rod.
EFFECT: simplicity of design and increased range of rotation of the variable-pitch propeller blades.
