Finned rudder with a main rudder pivotable about a vertical axis and a fin, joined to the rear edge of the main rudder and driven by the main rudder, to which a pivoting piston is connected, which is connected to a vertical shaft journal connected to the ship hull and which may be pivoted about the ship's longitudinal axis (X-axis) and the ship's transverse axis (Z-axis), independently of the deflection of the main rudder. The pivoting piston is inserted in a horizontal drilling (81) of a coupling housing (8) which has a vertical drilling (82) in which the joint bearing housing the shaft journal is inserted, made up of a spherical bearing with an inner ring (91) with a cylindrical drilling for housing the shaft journal and a spherical segment outer surface and an outer ring (92) with a spherical segment inner surface matching the spherical segment of the outer surface of the inner ring (91) and a cylindrical outer surface matching the vertical drilling (82) of the joint housing (8). |
