Definitions

  • the present invention relates to a "Z" type power transmission used in particular, but not exclusively, in the field of naval propulsion. It is associated with a motor located inside the hull and transmits power to the horizontal propeller shaft which is placed in a position such that the propeller does not interfere with the boundary or wake layer.
  • the most used type of transmission is the one that comes out of the stern mirror and, in nautical jargon, it is called “interior transmission - outboard" or "rear leg”.
  • Power transmissions of the "Z" type with transmission outside the hull guide the boat by means of the orientation of the axis of the propeller relative to to the longitudinal axis of the boat with the disadvantage that this orientation has a maximum angle of 30 ° to the right and 30 ° to the left and that the reversal of the direction of travel is achieved by reversing the direction of rotation of the 'propeller.
  • These conventional transmissions also have the disadvantage that the lifting of the foot in a vertical plane is limited by the presence on the transmission of a double universal joint and this lifting can reach a maximum value of approximately 50 °.
  • Torsion balancing systems are described in the following patents: US 2,755,765, US 3,094,967, GB 975,436, DE 1,165,442, US 3,486,478, US 3,750,616, US 3,851,614, and US 4,619,158.
  • the object of the present invention is to provide a power transmission in "Z" of the type mentioned above with a device shaped so as to allow variations in azimuthal orientation of 360 ° from the axis of the propeller or propellers. and that, of course, keeping the power transmission running.
  • Another object of the invention consists in shaping this transmission so as to allow lifting in a vertical plane, by rotation of the body which constitutes the foot, which can reach 180 ° with respect to the normal position while maintaining, in this case also , the power transmission on.
  • the drive shaft of the energy is coaxial and opposite a second shaft representative of the torque or moment of torsion applied to the means for the rotation of the first body.
  • This mechanism the operation of which ensures the guiding of the boat or of the ship, must withstand the reaction to the torque or moment of torsion transmitted by the inner shaft 3, a reaction which passes through the casing in the section under consideration.
  • the "Z" conformation of the transmission is defined by the drive shaft 10, the vertical shaft 3 and the propeller shaft 11.
  • FIG. 3 relates to the case where, along each of the two counter-rotating shafts 8 and 9, freewheel seals 12 and 13 are interposed.
  • the foot 1 maintains its position stably, unless a moment or torque tending to rotate it occurs.
  • the value of this moment must be equal to or greater than that transmitted, at this time, by one of the shafts: this moment is transmitted to foot 1 through the gear train 14, 15, 16 and 17 and the corresponding shafts among which, it should be observed, the tree 18 input representative of this moment and which is also that of guiding.
  • the gear 17 is integral with the foot 1.
  • the interposition of a friction clutch on the motor shaft 10 is suitable and it is advisable to use an auxiliary rudder for small variations in the route.
  • the operation of the foot in this case, should preferably occur when the motor transmits powers of modest value.
  • FIG. 4 relates to the case where, along each of the two counter-rotating shafts 8 and 9, a friction clutch 19 and 20 is interposed, respectively.
  • the clutches 19 and 20 are actuated, one at a time, automatically, before each control tending to rotate the foot 1, by a mechanism integrated in the guide system which is composed of the gears 14, 15, 16, 17 and by their trees.
  • the controlled clutch that is to say disconnected, is that concerning the shaft which, for this rotation, is requested to slide.
  • An auxiliary device not shown in this diagram, makes it possible to control the simultaneous detachment of the two clutches.
  • Figures 5 and 7 relate to the case where, between the drive shaft 10 and the two counter-rotating shafts 8, 9 of the foot, there is interposition of a differential 21 followed by two gear trains 22 with 23 and 24 with 25 with equal ratio, the gears 23 and 25 being respectively associated with the shafts 8 and 9.
  • the particular arrangement of the members as a whole makes it possible to eliminate this inverter and to carry out a lifting of the foot in a vertical plane in addition, naturally, to the orientation of the axis of the propeller in a horizontal plane.
  • the differential can be mounted near the propeller according to the diagrams in FIGS. 8, 9 and 10, the upper parts of which are as in FIG. 6.
  • the same function can have a differential connected to the outer shaft and the arrangements of the gears in the box of foot 1 can be different.
  • the torsional moment transmitted by the differential 29 arranged near the propeller is half that transmitted by the differential 21 provided in the upper part or box 2 of the diagrams in FIGS. 5 and 7.
  • the differential 31 is disposed between the final bevel gears 32, 33 and the shaft 11 of the propeller at a cross member 34 which carries the satellites 31 'of the differential 31.
  • the differential 35 is placed between the two horizontal coaxial shafts 36, rotating in the same direction, and the propeller 30.
  • the studs or trunnions 37 on which the satellites rotate are integral with the hub 30 'of the propeller.
  • FIG. 6 relates to the case where, in the box 38 of foot 1, each of the counter-rotating shafts 8, 9 transmits, through a bevel gear train, its torsional moment to its own individual propeller shaft 11 'and 11 "which necessarily in the diagram are offset. This is how the foot 1 is free to rotate and that the current system of gears transmits to it the command for its rotation.
  • a condition is imposed as regards concerns the considerations expressed previously, it is that the moments of torsion transmitted by the two counter-rotating shafts 8 and 9 are equal so that the reaction to these moments existing on the foot 1 is zero. condition, the more the difference between the powers absorbed by the two propellers tends to zero.
  • Figures 12 and 15 show two mechanisms which transmit the movement to two coaxial propellers 30, adjacent and rotating in the same direction.
  • the hydrodynamic characteristics of this pair of propellers, although predictable, are not known.
  • FIGS. 13 and 14 the propellers are arranged as in FIG. 6, but they are coaxial: in FIG. 13 they are counter-rotating, while in FIG. 14 they rotate in the same direction.
  • the invention in all of these embodiments can also be applied to other sectors, such as the wind and / or aeronautical sector.
  • FIGS. 18 and 19 The production of a transmission according to the diagram in FIG. 5 is illustrated by FIGS. 18 and 19.
  • the drive shaft 41 after a friction clutch and an elastic seal 42, leaves the stern mirror 43 and enters the box 44 where, by means of a bevel torque 45, 46, it drives the shaft 47 (which in practice corresponds to the motor shaft 10 shown diagrammatically in FIGS. 3-15) which carries, in orthogonal arrangement, the four studs or trunnions 48 on which are mounted four conical satellites 49 engaged all together with two bevel planetary gears 50: this coupling constitutes the differential (indicated at 21 in FIG. 5).
  • the bevel gears 50 are integral with each of the gears 51 and 52 which transmit the movement, with an identical ratio, to the counter-rotating vertical shafts 53 and 54 by means of their couples or bevel gears 55 and 56.
  • the control member is constituted by the transmission comprising the shaft 59 '(corresponding to the pipe shaft shown diagrammatically at 19 in FIGS. 3-15) and the gears 59, 60, 61 and 62, the final gear 62 being integral, via the hollow shaft 63, of the foot 64 containing the propeller shafts.
  • a hydraulic cylinder 65 by rotating the part 66, and therefore also the foot 64 around the sockets 67 and 68 coaxial with the shaft 47 and the shaft 59 ', determines the angle of lifting of the axes of the propellers in the vertical plane.
  • a simple device 69 prevents the lifting of the foot 64 when the propulsion thrust is directed towards the stern while it does not obstruct it when, as in the case of an impact impact, the foot is pushed to lift .
  • FIG. 20 The embodiment of a transmission according to the diagram in FIG. 7 is illustrated in FIG. 20, where the lower part is identical to that of FIGS. 18 and 19.
  • the driving energy arrives at the bell 72 by means of a bevel gear 73 integral with the latter.
  • the bell 72 carries studs or journals 74 on which the satellites 75 rotate which are simultaneously engaged with the sun gear 76 secured to the shaft 77 and with the sun gear 78 forming a single block with the bevel gear 79.
  • the shaft 77 transmits the movement of the planet wheel to the bevel gear 80.
  • the motive power arrives split, through the differential, to the counter-rotating vertical shafts 81 inside and 82 outside.
  • FIG. 21 The embodiment of a transmission according to the diagram in FIG. 11 is illustrated in FIG. 21 applied to a hull (planing) prepared for the application of two motors and two transmissions in "Z" according to the diagram in FIG. 22 which represents said shell seen from above.
  • the engine torque or moment of torque arrives at the shaft 88 ′ and therefore at the bevel gear 88 through a friction clutch 89 and an elastic seal 90 and is distributed through the gears 91 and 92, to the counter-rotating coaxial shafts 93 and 94.
  • These transmit the movement intended for the counter-rotating propellers 95 and 96 located in the foot 97 (which is shown here rotated 90 ° relative to the direction normal), each for its own account, by means of two bevel gear trains 98 and 99, with two coaxial shafts 100 inside and 101 outside corresponding respectively to 11 'and 11 "of the diagram in FIG. 11.
  • the propeller 96 is of variable pitch (conventional) with adjustment from the outside so as to be able to make the torsional moments transmitted by the two vertical counter-rotating shafts identical.
