HYDRAULIC ROTARY-BLADE PIVOT DRIVE FOR HYDRO-STABILIZERS AND RUDDER SYSTEMS

摘要

A hydraulic rotary-blade pivot drive for hydro-stabilizers and rudder systems, particularly on ships, with receiving grooves on the external sides of the rotor blades and/or the inside of the stator blades, and with sealing strips and elastic elements which are radially displaceable in said receiving grooves. Slave blades are provided between the sealing strips and the elastic elements over the entire length of the rotor. The slave blades are held in the receiving grooves with clearance so as to be radially displaceable and project beyond the outsides of the rotor blades and the insides of the stator blades and are designed to ensure hermeticity on all sides. The sealing strips together with the slave blades and the elastic element form one single sealing unit.
