Definitions

  • the invention relates to a ship control surface comprising a seat forming part of the structure of the ship, in which is pivotally mounted a rudder, said rudder being controlled in angular position by a motor.
  • the invention applies more particularly to a large ship such than a liner in which the servo in rudder position is assisted by machinery.
  • the rudder is linked in movement to at least two hydraulic motors which are supplied with pressurized oil by a hydraulic central.
  • This hydraulic power station itself comprises two electric motors powered by an electrical network to ensure redundancy in the control of the rudder.
  • the rudder which is movable in rotation along a vertical axis includes in its upper part a toothed crown located in a horizontal plane, and a output pinion of each hydraulic motor is meshed in this crown to transmit a torque to the rudder.
  • This solution requires the implementation of one or more power plants hydraulics associated with high pressure pipes which occupy a large volume and require specific maintenance.
  • the object of the invention is to remedy these drawbacks by proposing a an electric servo control having a space requirement reduced and requiring minimal maintenance.
  • the invention relates to a ship's steering system comprising a seat forming part of the structure of the ship, in which is mounted pivoting a rudder, said rudder being slaved in angular position by a motor, characterized in that said motor is an electric motor comprising a stator rigidly fixed to said seat, and a rotor rigidly attached to said rudder.
  • This motor which is an orientation motor transmits the torque required to control the rudder by track electromagnetic, i.e. without physical contact, which eliminates wear problems. Maintaining a fixed position is then carried out by a power supply adapted to the type of electric motor in place.
  • the rudder includes a steering cone pivotally mounted in the seat, and the engine electric is mounted inside this control cone. congestion of the control surface according to the invention is thus further reduced.
  • the rudder can include a submerged part in the form of a saffron, or else under shape of a bulb containing a propulsion engine of the ship.
  • the cooling of the orientation motor can be by deflecting part of the ventilation intended for the motor of propulsion. It is thus not necessary to implement means additional ventilation specially dedicated to cooling the slewing motor.
  • the stator comprises multiple windings which are powered by electrical sources independent. These electrical sources could be converters of dedicated power, thus ensuring redundancy in the function of servo-control, to ensure the safe operation of the control surface according to the invention.
  • the single figure is a sectional view of the control surface according to the invention.
  • a ship's control surface includes a rudder 1 rotatably mounted in a seat 2 which is integral with the structure of a ship not shown.
  • the rudder 1 here comprises a control cone 1 'connected to the seat 2 by a rotary mechanical connection 3, so that it is suitable to rotate around a vertical axis AX along which it extends.
  • This cone of rudder 1 'crosses the structure of the ship in a sealed manner to maintain a submerged part 1 "shown partially in the figure.
  • This part submerged 1 is rigidly fixed to the control cone 1" and forms the part active rudder 1 to steer the ship on a certain dependent heading from its position around the axis AX.
  • the angular position of the rudder 1 around the axis AX is controlled by controlling the angular position of the cone which is located inside the ship.
  • the control cone 1 has a diameter which decreases from top to bottom, and it plunges into the seat which forms a conical well substantially complementary.
  • the rotary link 3 is located in a plane horizontal of the upper part of the control cone 1 'corresponding to the part of larger diameter of this cone.
  • a circular joint 4 surrounds the low diameter low part of the control cone to ensure tightness with the lower part of the seat 2 which is also weak diameter.
  • a toothed crown internal is usually mounted inside the top of the cone, so that hydraulic or electric motors having their pinions meshed in this internal toothing are able to move in rotation of the rudder around the axis AX.
  • this drive system with a ring gear linked in rotation to motors is replaced by a single large motor diameter said orientation motor, mainly comprising a rotor 5 rigidly fixed to the rudder 1, cooperating with a stator 6 which is rigidly fixed to the seat 2.
  • the rotor 5 and the stator 6 are chosen large diameters to facilitate the transmission of large torques.
  • Such an engine of orientation may be designed so as to surround the control cone 1 ', or on the contrary be mounted inside this control cone in in order to reduce the size of the control surface, this choice being conditioned by sizing requirements corresponding in particular to powers to be brought into play in the motor to achieve servo-control.
  • the motor is mounted at inside the upper part of the control cone 1 '.
  • the rotor 5 which substantially defines a toroidal shape is positioned in a horizontal plane by being fixed to the internal surface of the control cone 1. It cooperates with the stator 6 which also has a generally toroidal shape but of weaker diameter, and which is mounted inside the rotor 5 in the same plane horizontal than the latter. More particularly, the stator 5 plunges into the control cone 1 'while being held in its upper part by a circular cover 7 of large diameter covering the control cone and fixed rigidly to the seat 2.
  • stator comprising 5 'windings electrically powered by a 8 power converter such as frequency and voltage converter variables connected to a power supply network of the ship.
  • the rotor 6 is here passive and mainly comprises 6 'squirrel cages arranged on along its outer periphery, to form with the stator a motor asynchronous.
  • the implementation of such an asynchronous motor presents in in addition to the advantage of facilitating the locking in position of the rudder by adjusting the frequency of supply of the motor to that of the sliding of the rotor so as to cancel the mechanical speed of said rotor.
  • This arrangement consisting in mounting the windings on the stator at place of mounting them on the rotor is interesting for the implementation of several windings each supplied by a power converter dedicated to him.
  • the amount of wiring is increased, but these wiring are connected to the stator which is fixed, which simplifies their installation.
  • Setting work of several windings fed separately ensures in addition redundancy in the position control function which improves the operational safety of the control surface according to the invention.
  • the submerged part 1 ′ of the rudder 1 can be a rudder, or a bulb containing an electric motor propelling the ship, also called pod.
  • this propulsion engine is generally cooled by a ventilation system circulating an air flow in the bulb.
  • This air flow enters the upper part of the control surface through a circular opening 7 ' made in the cover 7, which is indicated by the arrow R in the figure.
  • this air flow is also used to cool the slewing motor, so there is no need to provide additional resources dedicated to cooling the slewing motor of the rudder.
  • control surface comprises a conical connection
  • control surface comprises a conical connection
