Rudder mechanism for marine vessel

摘要

A rudder mechanism for a marine vessel comprising of rudder that contains a first water flow surface essentially in planar form and an opposite second water flow surface essentially in planar form; a vertical rudder shaft that the rudder is linked by rotation around an axis that essentially extends perpendicular to the water flow surfaces of said rudder; and a drive mechanism for rotating the rudder around said axis. The rudder mechanism contains a rudder slot comprising the vertical rudder shaft and extending from the top section of the rudder towards the bottom section, wherein the rotatable link of the rudder and the vertical rudder shaft is essentially located close to the bottom of said rudder slot and is essentially linked to the vertical rudder shaft of said drive mechanism in such manner to exert force in the radial direction.

1. A rudder mechanism for a marine vessel comprising:
a rudder (1) having an upper side, a lower side, a first water flow surface (2) having substantially planar form and an opposite second water flow surface (3) having substantially planar form; a vertical rudder shaft (7) rotatably communicating with the rudder (1) about an axis that substantially extending perpendicular to the water flow surfaces of the rudder (1); and a drive mechanism for rotating the rudder (1) around the axis, the rudder mechanism further comprises a rudder slot (4) extending from the upper side of the rudder (1) towards the bottom side thereof for receiving the vertical rudder shaft (7); wherein the rotatable communication of the rudder (1) and the vertical rudder shaft (7) is provided substantially close to a rudder slot bottom (16) and the drive mechanism is communicated with the vertical rudder shaft (7) to exert force in the radial direction thereto.
