Definitions

  • the invention refers to a propeller tail for boats to be mainly applied to yachts, coastal fishing boats and the like, the tail itself being structured and made up in such a way that it may be mounted either internally or externally, with respect to the boat itself.
  • the propeller tail intends that the boat to which it is applied may have a greater manoeuverability and reach a higher cruising speed, having an effect not only on a higher economic use of the boat itself, but also on the possibility of riding out bad sea conditions with greater safety.
  • Propeller tails manufactured at present in the recreational scope range up to medium length or are designed for trailing in ferry boats or dredges, where cruising speed does not have priority.
  • tails used for recreational boats include a generally low quality, aluminium-alloy-casing, with integrated gearing which occupies a big volume, and may be mounted externally with respect to the boat.
  • the steering of the boat is done by turning the whole body of the tail by means of ball-and-socket joints, and that requires the fitting of rubber seals for the watertightness between the tail and the boat, in such a way that sea water quickly causes wear and tear to the said pice of rubber and enters the boat, causing premature mechanical perishing.
  • sea water for mechanical cooling flows through the inner part of the casing, depositing dirt and contributing not only to its rapid wear, but also to the diminishing of its mechanical cooling capacity.
  • tail shafts independently of fishing vessels which are usually equipped with outboard engines, all other boats mount tail shafts, the same occurring with yachts, so that the aforementioned tail shaft implies a low speed when working with water disturbed by the hull, as well as lower manoeuvring capacity and greater space occupation, having an effect in the bailing of holds in fishing vessels, whereas in yachts they are generally under-used, reaching sometimes up to 50% of its overall surface, basically in those of short length.
  • the propeller tail which is proposed has been conceived to the end of solving completely the problems previously stated, showing a great mechanical simplicity, with an oversize in order to avoid possible failure and to withstand the most adverse working conditions, also showing the peculiarity that the tail may be mounted either inside the boat or hanging above the upper stern, this is to say, externally.
  • the group engine-gear-tail makes up a compact unit which is assembled over a metallic framework, without any kind of transmission, occupying therefore a minimum space and ruling out sometimes the engineroom. If we add that the casing is made of bronze and manganese, guaranteeing the rigidity of the mechanical drive and the sea corrosion resistance, it is obvious that the propeller tail of the invention is highly advantageous in comparison with those presently known.
  • the propeller tail of the invention comprises two truncated groups linked to each other by means of a central connection shaft, in such a way that one of the groups, through a crown, receives the moving power coming from the corresponding engine, whereas the other, through another crown, transmits movement to the shaft carrying the propeller, the unit of the double truncated group with their shaft, pinions and crown being immersed in oil and placed logically in a general casing, with races, O- rings joints, adjusting nuts, etc.
  • the pump on the basis of which a flow of continuous oil may be created from one end of the tail itself, to the other, achieving efficient cooling and a perfect thermal balance, the pump being based on two single pieces with no contact between them, so there would neither be wear nor possible failure, the pieces or components of which are an upper cover fixed to the general casing of the tail and a shaft carrying the crown which receives the rotation power coming from the engine, all of that with the peculiarity that, in order to achieve a higher performance and efficiency, the oil must be drawn in by the upper part of the aforementioned shaft carrying the crown and expelled by the corresponding attack pinion which is the means of interconnection between the lower end of the shaft and the lower truncated group, through which the shaft of the propeller itself is pushed.
  • the stern also has a hydraulic steering system integrated by an hydraulic rotation rack in mesh with the corresponding toothed crown.
  • the said propeller tail is intended to be mounted internally, including the corresponding nozzle, or mounted externally, in which case it will be fixed, by means of a metallic support, to the respective boat stern, incorporating. in this case flaps of big surface, with the advantages that that implies.
  • the propeller tail which is the object of the invention, intended for external mounting, includes a general casing determined by the linking between parts (1), (2) and (3), part (1) corresponding to the so-called upper part, part (2) to the intermediate, and part (3) to the lower part, the general body (4) being fixed to the latter in the lower part by a bulb cover (5), in the body (4) of which the propeller (6) itself is placed.
  • General casing defined as aforementioned has a lateral part (7) in which the attack pinion (8) is placed and which receives the power from the corresponding engine-gear group with the characteristic that from that pinion (8) pushes a crown (9) mounted over the shaft (10) corresponding to the upper truncated group (11), which is related to the lower truncated group (12) by means of an axial shaft (13), with the insertion of the corresponding attack pinions (14).
  • the tail is watertight to sea water, and is installed completely full of oil as previously explained, with an expansion cup in the upper level, in such a way that when working, sea water cools its external lower part, at the same time as the oil does so inside.
  • Rotation are complemented with the respective races (16), with securing nuts, etc., showing in the upper part the respective race-carriers (17).
  • the corresponding watertight O-rings joints (18) are included as well as the oil-entrance- connection (19), being complemented with regulating grommets (20) for the truncated groups (11) and (12).
  • the propeller (6) is mounted over the lower body (4), and more precisely over the so-called tail shaft (21), being fixed to it by means of a nut (22), and in the shaft (21) of which a crown (23) is placed, which receives power from the lower truncated group (12), as the upper crown (9) belonging to the upper truncated group (11) receives it from the attack pinion (8) through which connection to the engine takes place.
  • the propeller tail so-built forms part of a compact whole and is intended to be anchored externally, specifically to the upper stern (23) of the boat, by means of a metallic support (24) joined to the boat, as well as a fastening plate (25), in such a way that the joint of the latter to the support and to the casing of the tail takes place by means of respective silentbloc (26).
  • the engine and the gear are mounted internally, over the metallic frame, the space occupied by the driving set being therefore reduced, boats of short length being basically benefitted.
  • the tail so-built is intended to transmit to the water the power which it receives from the engine through the gear, the final reduction taking place between the engine and the propeller by means of a combination of the two truncated groups (11) and (12) and not in the gear as traditionally happens; all of these in such a way that the transmission of power from the elastic coupling which joins the gear and the tail itself goes through the following mechanisms: upper attack pinion (8), upper crown (9), upper truncated group shaft (10), central connection shaft (13), lower attack pinion (14), lower truncated group (12), lower crown (23), tail shaft (21) and propeller (6).
  • the propeller tail is watertight to sea water and is installed completely full of oil and with an expansion cup in the upper level, in such a way that, when working, sea water cools its external lower part, at the same time as oil cools its inner part.
  • the same is represented in picture no. 3 and includes a crown (27) and a rack (28), in such a way that a orbitrol attached to the rudder of the boat shall govern the flow of oil in that hydraulic rack (28) mounted in the propeller tail itself.
  • the said steering hydraulic system as a whole, has been designed bearing in mind the fitting of one, two or more tails per boat.
  • This hydraulic system includes a piston (29) and an exit ram (30), it having two closing covers (31) and (32), the first of them as a dead light and the second as a perforated lid for the exit of the ram (30), this being intended in order to synchronise the rotation in the event that two propeller tails are mounted.
  • the said system is completed with friction bands (33), collars (34) and bearing scraper (35), as well as with a fork (37), with adjusts the synchroniced rotation of two tails, and a silentbloc (38), a slide (39), an adjusting bolt (40) and a tightening nut (41).
