Definitions

  • the present invention concerns a transmission set for motorboats comprising a box-shaped body for containing and a for a jointed support onto two axis, perpendicular one to the other, and a box-shaped set for containing and support that may be operatively engaged to the stern part of the hull and passing inside with an o-ring watertight system, and an internal blocking counter-plate that works as a support for the resting of two rotating elastic supports which allow a pre-positioning with a fixed point of the joint of the motion transmission inverter of the engine.
  • the transmission set according to the present invention may be used in a particularly advantageous manner on motorboats of the planing, inboard kind.
  • a second typology of motion transmission of an inboard motor is the so-called stern foot, that allows to transfer the outlet power from the motor shaft to a horizontal outlet shaft, placed downwards with respect to the position of the motor shaft, so as to support one or more propellers below the floating line of the boat.
  • Such a transmission set mainly provides that inside a containing, box-shaped body, a substantially horizontal shaft is housed, besides said outlet shaft, that takes the rotating motion from the motor shaft and transmits it to the outlet shaft by means of an intermediate, mainly vertical shaft, respectively interconnected to the inlet and outlet shafts by means of a first and a second pair of conical cog wheels.
  • Said solution allows to place the motor near the stern of the board and therefore to considerably reduce the length and the encumbrance of the transmission shaft, in line with said motor.
  • a third typology, the most up-to-date and presently used one, is the so-called surface transmission which, even if it is applied like the stern foot to the stern of the boat, makes use of only one outlet shaft which, with a rather low inclination, transports the rotating motion of the motor outside of the boat, moving away from the hull until a so-called surface propeller may be applied which is immersed to the centre of its hub.
  • document IT 01307592 (Gabriele et al.) is known in which for lowering the considerable costs of the industrial realization of a ball and of its housing, allowing the rotation thereof, the rotation is provided only on two axis: one, vertical to the direction of the boat's motion and one perpendicular to the same.
  • the present invention makes use of a bi-axal solution, i.e. a ring with a circular or polygonal crown with an even number of sides from four on, such as to hook, on the same plane, by means of special and dimensioned pins working on bushes out of suitable material, two movements perpendicular one to another, leaving inside the possibility of making pass a cardan joint that allows, with very small angular movements, the transmission of the motion from a rotating axis solidly engaged with a movable axis.
  • the present invention allows to considerably reduce the costs and, in the same time it allows, making use of materials of common industrial realization, a wide dimensioning choice and thus the applicable power is linked only to a simple calculation of diameters and torsional resistances and size and typology of the bearings.
  • the materials used are easily available and therefore may be bought at very low prices.
  • connection inside the boat's hull between the transmission and the motor and/or the motion inverter is assured by means of a second cardan joint that therefore allows the independence between the two coupling planes as one is firmly linked to said boat and one oscillates on elastic supports in position and in hooking.
  • a fixing bracket which at the same time allows to firmly block the containing box linked and engaged to the stern of the hull, in an absolutely invariable position.
  • Said bracket is provided with two longitudinal arms placed in such a way as to support in a fixed point a rotating propeller element.
  • Such shape allows to receive the hooking of the stern part of the motor or of the inverter connected to the motor, in a constant manner, placed in height and in distance, but with the possibility of rotating in a radial direction with respect to the centre of above mentioned elastic support of the stern, and therefore of giving the possibility of placing in the position considered the most appropriate said elastic supports of the stern of the engine, whereby the installer must not inquire about the distance and/or the height of the motor-transmission coupling. From all above, it results how easy said installation may be and how cheap.
  • FIGS. 1, 2 and 3 show the counter-plate of the inner transmission set and the details for fixing the support on astern;
  • FIG. 4 shows a lateral scheme of the installation of the transmission set.
  • the enclosed figures show a transmission set for motorboats according to the present invention, comprising:
