Definitions
- the present invention relates to a propulsion system for boats or ships of all kinds wherein, in addition to a main propeller, a secondary propeller rotates contrary to the main propeller, in order to optimize the propulsion and eliminate cavitations.
- the object of the invention is to ensure, on one hand, that the main engine of the ship can move both contra-rotating propellers simultaneously, which in determined circumstances can be supported by an electric engine and, on the other, that even the propulsion can be carried out exclusively by said electric engine, when for different reasons and as we will see later on, it is necessary or advisable to reduce the ship's acoustic contamination to a maximum.
- one of the objectives of this invention is to resolve all the aforementioned disadvantages by providing a mechanism or mechanical device that allows the installation of a conventional in-line contra-rotating double propeller, and which can also be assembled in pre-existing ships without the need for complex mechanical or structural transformations.
- the main shaft of the ship which in turn bears the main propeller and is associated to the main engine thereof, normally an internal combustion engine, is divided into two in its terminal sector in a secondary, tubular shaft, coaxially assembled on the main shaft and solidly joined to the corresponding secondary or contra-rotating propeller with respect to the primary, main propeller, both shafts being inter-related through a set of gear wheels, that not only transmits the movement of the main shaft to the secondary shaft but also reverses the direction of rotation to achieve the contra-rotation of the propellers.
- the intermediate bevel gear wheel that of the geometrical axis perpendicular to the primary and secondary shafts, is associated through a clutch to an electric propulsion engine, that transmits the movement of both shafts, i.e. both the primary and secondary shafts, through the other two bevel gear wheels, in such a manner that said electric engine can be inoperative when deemed convenient, can support the internal combustion engine when necessary, or can act in an isolated manner, i.e.
- the electric engine will also be assisted by a clutch, and said engine shall be controlled by a frequency variator governed from the ship's bridge.
- FIG. 1 a general diagram of the whole power unit of the ship has been represented in Figure 1 , specifically the rudder (1), the main propeller (2) and the contra-propeller (2'), the coil (3) by means of which the shaft line (4) rotates over the hull of the ship, the case (5) that houses the transmission means corresponding to the hybrid propulsion system of the invention in its interior, the secondary engine (6) that participates in said system with its corresponding clutch and reducer (7), and the elastic coupling (8) and reducer (9) corresponding to the main engine (10).
- the main engine (10) is of the internal combustion type and the secondary engine (6) is electric.
- the case (5) is crossed by the primary shaft (11) corresponding to the main propeller (2) and stemming from the main engine (10), and the secondary shaft (12), that corresponding to the secondary propeller or contra-propeller (2'), is established coaxially on the primary shaft (11) approximately halfway down said case.
- a first bevel gear wheel (14) is joined by a series of tightening conical rings (13) to the primary shaft (11), conveniently watertighted with respect to the case (5) in the penetration area of the latter, which rotates jointly with said primary shaft (11) and is coaxial thereto.
- a second bevel gear wheel (15) is engaged with this bevel gear wheel (14), having a perpendicular axis to the primary shaft (11) which, as in the case of the bevel wheel (14), is assembled on the case (5) by means of bearings (16), said second bevel gear wheel (15) being engaged with a third bevel gear wheel (17), also assembled on the ball bearing (16) and conveniently fixed to the secondary shaft (12) by a flange (18).
- This transmission causes the secondary shaft (12) to rotate contrary to that of the primary shaft (11), consequently causing the main propeller (2) to rotate in turn contrary to that of the secondary propeller (2').
- the intermediate bevel gear wheel (15), more specifically the shaft thereof, is conveniently associated through said clutch and reducer (7) to the secondary engine (6), which by means of the transmission of the aforementioned bevel gear wheels (14, 15 and 17), is capable of transmitting movement to both the primary shaft (11) and secondary shaft (12).
- the secondary engine (6) can be substituted for two smaller and opposing secondary engines (6-6'), as shown in Figure 4 , in which case the shafts of said engines (6-6') end in respective bevel gear wheels (19-19'), which engage with an intermediate crown wheel (20) opposed and coaxially associated to the bevel gear wheel (15) pertaining to the main, previously described transmission.
- the secondary engines (6, 6') are electric.
- an oiling circuit comprised of an oil tank (21) established in the lower part of the case (5), from which a pressure pump, not represented, draws oil, through an intake filter (22) and injects it in a point (23) located on the inlet of the primary shaft (11) in the case (5), and complementarily at the inlets (24) located in the upper part of the case corresponding to the clutch-reducer unit (7) established between the electric engine (6) and the main transmission, the oil returning to the tank (21) by gravity, via a return (25).
- the system has a second intake filter (26), using the first filter (22) for oiling under normal conditions, and the second filter (26) for oiling with an emergency unit.
- this oiling circuit shall be double, a circumstance that explains the presence of the two aforementioned intake filters (22, 26).
- an external pressure regulating valve is installed at the pressure outlet of said pump which has an inlet and two outlets, in such a manner that said pressure firstly reaches the inlet (23) and, on exceeding a predetermined pressure, an external regulating valve diverts the flow toward the inlets (24).
- a coolant is inserted, specifically between the filter and the upper oiling inlet.
- Said coolant can be water-oil, or air-oil, necessarily including, in the latter case, an electric fan.
