Definitions

  • the present invention relates to a thruster for a boat, in particular a thruster equipped with a retractable and steerable propeller, and a boat equipped with such a thruster.
  • Many boat thrusters are equipped with a motor with a first axis, a propeller with a second axis, and a transmission element between these two axes.
  • the transmission between the engine and the shaft of the propeller is made by means of a belt.
  • the belt is faired, but this fairing generates a significant drag resulting in a loss of hydrodynamics mainly at high speed.
  • An object of the present invention is to provide a thruster free of limitations of known documents.
  • Another object of the present invention is to provide a more hydrodynamic propellant.
  • Another object of the present invention is to have a simple, original, quiet and inexpensive system.
  • Another object of the present invention is to provide a thruster with a retractable and steerable function, in a small footprint, and employable in all the different configurations commonly used on boats.
  • the connecting arm comprises two sections spaced apart from each other, a single strand passing through each section.
  • the belt may be a closed belt.
  • strand refers to each of the two portions of this belt between a pulley on the axis of the propeller and a pulley on the axis of the engine.
  • the thruster link arm may be unsealed.
  • the water can thus enter the link arm, be driven by the belt, and used for cooling the thruster.
  • the propeller (or each propeller) can be housed in a bulb and each propeller can be mounted on a rotating axis. Each propeller can also be removably mounted on the rotating shaft. This makes it possible to replace the propeller easily, without disassembling the bulb or the arm.
  • the first rotatable assembly is intended to be manually rotated.
  • the thruster comprises a first electric motor for pivoting the first rotary assembly.
  • the thruster may comprise two opposing belts fixed at their ends to the fairing portion and put into traction by the first electric motor to rotate the first rotary assembly to orient the propeller relative to the boat.
  • the second assembly adapted to be translated relative to the first rotary assembly in order to retract the propeller is intended to be manually translated.
  • the thruster comprises a second electric motor for translating the second set.
  • the present invention also relates to a boat comprising a thruster according to the present invention.
  • the propeller shown on the figure 1 comprises in particular a motor 100, a connecting arm 200, a propeller 302 and a belt 2.
  • the motor 100 may be an electric or hydraulic motor. It provides the energy needed to move the boat forward. This energy is transmitted to the propeller 302 by means of the belt 2.
  • the engine can also operate as a generator for charging a battery of the boat in the case of a sailboat advancing under sail.
  • belt designates smooth or notched belts, or equivalent elements for example chains.
  • the belt 2 can be notched or smooth. This belt 2 forms two strands between the engine 100 and the propeller 302.
  • the connecting arm 200 is unsealed and comprises two hollow profiles 202 with a fine outer section favoring its passage in the water, better visible on the figure 2a .
  • a single strand of the belt passes through each profile 202.
  • the belt thus receives energy from a pulley on the axis of the motor 100, passes through a first profile 202, transmits its energy to the pulley, then returns to the axis of the motor by the second section 202.
  • the two profiles 202 have a hydrodynamic profile of drifts. They are kept apart and can be parallel to each other or not. Two covers 203 allow to close the two hollow profiles 202 and fair them once the belt has been introduced. These profiles can be made of a composite material and are fixed at the top on the mobile carriages 501, and down in the bulb 300 of the propeller 302, as will be seen.
  • the assembly can be performed by first conical inserts 204 which allow a blocking quality without play and without risk of loosening regardless of the stability of the geometric dimensions of the material used.
  • the locking by screw of these conical inserts 204 placed in opposition or not is achieved by means of a first spacer 206 adjusted along the length according to the geometry of the mounted elements.
  • the belt is driven by a single pulley 4 and the two sections are connected to a single propeller 302.
  • the distance between the two sections 202 is given by the diameter of the pulley 4 which can be between 40 mm and 800 mm.
  • a large pulley diameter allows the belt to transmit a significant engine torque with a significant service life. They also make it possible to keep the two fins sufficiently spaced to give a great rigidity to the link arm.
  • the belt is driven by two pulleys 4, 4 '.
  • the thruster comprises two propellers 302, 302 ', each propeller being mounted in a bulb.
  • the two bulbs are interconnected by a foil 201 in the shape of an airplane wing.
  • the belt 2 passes through the first profile 202, drives the first helix in the first bulb, passes through the foil 201, drives the second helix in the second bulb, then returns to the engine by the second section 202.
  • the distance between the two profiles is given by the radius of the pulleys plus the gap between the pulleys.
  • the bulb 300 of the propeller 302 comprises a toothed pulley 306 driven by the belt 2 inside the bulb, a rotating shaft 311 and a fixed axis 312.

  • the axis of the pulley can also be mounted with two deep groove ball bearings, roller bearings, needle bearings, thrust ball bearing or needle, tapered bearings or any other type of bearing. allowing to take the radial and axial efforts.
  • the toothed pulley 306 is thus rotated about the fixed axis 312 which is maintained in the nose of the bulb 322 and blocked at the front by a second conical insert 314 and a second spacer 316.
  • the propeller is mounted on the rotating shaft 311 whose rotation is driven by the pulley 306 thus allowing the rotation of the propeller.
  • the flank 304 geometrically connects the outer diameter of the nose of the bulb 322 with the outer diameter of the helix.
  • the shape of the bulb 300 promotes the passage in the water, which allows the boat to gain hydrodynamism.
  • the emptying of the oil in the bulb is done by opening a plug 324 threaded and internal to the bulb.
  • the belt 2 carries with it the water which is compressed at the passage of the pulley 306. This water is recovered for cooling the motor 100.
  • the thruster is connected to the boat by the fairing portion 208 fixed relative to the hull of the boat.
  • a first rotary assembly 400 can turn manually or motorized relative to the first fairing portion 208 around an upwardly facing geometric axis, so as to orient the propeller relative to the boat to rotate it.
  • the fairing portion 208 comprises an open, rigid and advantageously cylindrical envelope with a round, square or any other section.

  • each barrel is equipped with a self-lubricating bearing bush 412, locked in position. rotation by a fixed pin 414 attached to the respective flange.
  • the housing of the insert in the flange is sized to allow the mounting of a member 416 flexible polymer or O-rings.
  • the weight of the mechanical assembly is supported by the upper flange 402 and transmitted to the fairing portion 208 by the bearing 6 which allows the rotational assembly 400 to rotate.
  • An elastomeric spacer 8 absorbs the vibrations of the engine thus avoiding to transmit them to the hull of the boat and thus reduce the noise.
  • the upper flange 402 and the lower flange 404 interconnected by the rods 406 absorb the torque created by the thrust of the propeller 302 and the tension force of the toothed belt 2.
  • the first rotary assembly can be rotated relative to the fairing portion.
  • the profiles 202 being integral in rotation of the rods 406, this rotation is transmitted to the profiles and therefore to the bulbs 300 and the propellers 302.
  • the first rotatable assembly 400 may be manually rotated relative to the fairing portion.
  • an electric motor 102 visible in particular on the figure 4a , is provided for this purpose.
  • This motor drives a pulley 104 with vertical axis, which in turn drives via a belt 106 the axis of orientation 108 equipped with a driven pulley 110 and a rolling bearing ball 112.
  • Two flat belts 116 and 118 are attached at one end to the fairing portion 208 and at the other end to a bearing of the orientation axis 108, so that the first flat belt 116 is unwound and the second belt 118 is wound when the engine rotates in a first direction, and vice versa when the engine rotates in the other direction.
