Reference Answer
A vane-type steering gear uses a rotor and stator mechanism where the vanes create hydraulic chambers to control the movement of the rudder.
The rotor is fitted to the tapered rudder stock. The rudder stock carries the weight of the rudder, supported by a rudder carrier bearing.
The stator is fixed to the ship’s structure, forming a rigid support.
The fixed vanes are evenly spaced inside the stator bore, while the rotating vanes are equally spaced on the rotor.
