Definitions

  • the present invention relates to an arrangement in connection with a swingable turn-up inboard/outboard stern aggregate for craft with an inboard engine and an outboard drive unit comprising a screw, and of a kind as stated in the preamble of the following independent claim 1.
  • Such a stern aggregate is known from the applicant's previous NO-PS No. 158 335, the object of which was to reduce dimensions, especially the transversal dimension, of the lower portion of the housing surrounding the propeler shaft and screw shaft with bearings by using universal joints between the propeler shaft and the screw shaft.
  • reversal of the direction of screw rotation may either be achieved by the aid of a gearbox in said inboard engine or, if desired, in the transmission from the latter to the stern aggregate.
  • the last mentioned concept will require space between the engine and the stern of the craft and it will also form an independent unit which has to be mounted, i.e. inserted between the stern aggregate and the engine.
  • Figure 1 shows an inboard/outboard stern aggregate 1 the fastening means 1a of which is mounted on the stern of craft 10, and a driving unit 2 which is swingably fastened to fastening means 1a, via a horizontal transversal axis D ( Figure 2) and an approximately vertical axis E, for lifting, and lowering, respectively, of driving unit 2 and for swinging driving unit 2 to steer craft 10 in motion.
  • an inboard driving shaft 3 is mounted for connection with output shaft 3a, via a flange coupling 3b.
  • a driving shaft 3 is connected with a transmission shaft 6 which is divided into two sections 6a, 6b.
  • the first section 6a is mounted at the upper end of housing 7 and connected with said universal joint A, and its second end is connected with the second section 6b of transmission shaft 6, via angular gear B.
  • the lower end of section 6b is, via a universal joint C, preferably a double universal joint, connected with a screw shaft 4, which is mounted in the lower rear end of housing 7, with a firm angle V between screw shaft 4 and lower section 6b of transmission shaft 6, which angle V is smaller than 45°, preferably 32°, with an approximately horizontal screw shaft 4.
  • Universal joints A and C may, e.g. be of the ball-and-socket kind which may transmit high moments of torsion relative to its moderate external dimensions.
  • housing 7 and a lower portion of the same which forms the screw housing 7a may be built with small transversal dimensions.
  • the screw housing may, thus, be made narrow to reduce its resistance to water flow.
  • the drawing shows that universal joints of the cardan type are used in the present case, and it is especially important to be able to use a double universal joint of the cardan type forming a transmission means C for torsional moment between lower section 6b of transmission shaft 6 and screw shaft 4 so as to reduce the bending loads on the universal joint and, thus, to reduce any vibration and loss of transmitted torsional moment to screw 5.
  • a stabilizing plate 11 is provided. It is fastened to and extends rearwards from housing 7 in an approximately horizontal plane and in the waterline when the craft is in motion.
  • driving unit 2 may be turned up and down and the inclined position of driving unit 2 is adjustable in order to provide the most suitable angle of attack of screw 5 in the direction of motion.
  • a pressure cylinder 12 is provided as shown in Figure 2.
  • the above mentioned reversing means for changing the direction of rotation of screw 5 as well as for cutting off the same is designated D and is arranged together with angular gear B connecting upper section 6a of transmission shaft 6 with its lower section 6b.
  • angular gear B comprises two sets B1 and B2 of conical gears 11a, 11b, and 12a, 12b, with driving gears 11a, 12a being mounted to be engageable and disengageable on first/upper section 6a of transmission shaft 6 and being engaged with the driven gearwheels 11b, 12b, which are provided in a mutually non-rotatable engagement with the second section 6b.
  • a conical intermediate gear 12c is arranged between the driving and the driven gear 12a, 12b to provide for opposite directions of rotation of section 6b when one or the other driving gear 11a, 12a is engaged, or disengaged, respectively.
  • clutches 13, 14 are provided in connection with respective gears 11a, 12a and are controlled from a manoeuvring central 15.
  • Clutches 13, 14 are preferably air-oil actuated, the compressed fluid being supplied, via conduits 16, 17 in housing 7 to annular chambers 18, 19 in section 6a and, via bores 20, 21 in section 6a to a motor (not shown) in each clutch 13,14.
  • the clutches may be sliding clutches with one set of disks being fastened to section 6a and the other set being fastened to driving gears 11a, 12a, which two sets of frictional disks are made to contact each other by the aid of said pressure motor in each of the clutches 13, 14 by the aid of manoeuvring central 15 which is controlled by suitable means from the driver's seat in craft 10.
  • annular chambers 18, 19 are provided between driving gears 11a, 12a and may either consist of annular flanges, which are provided on section 6a and cooperate with an annular surface provided in housing 7, and with conduits 16, 17 opening into a respective annular chamber.
  • the annular chamber obviously, may consist of annular flanges extending inwards from said annular surface and being in contact with a corresponding external bearing surface on section 6a. From each of said annular chambers 18, 19 bores 20, 21 extend in section 6a to a pressure motor in each clutch 13, 14.
  • the driven gears 11b, 12b on section B are connected with each other in a manner preventing relative rotation, if desired, via splines 6c, and said gears may also be connected with section 6b, via said splines 6c to be mutually nonrotating. This is so to permit movement/ elongation of section 6b, among others in case of changes of temperature, without influencing the position of gears 11b, 12b relative to the driving gears 11a, 12a, and intermediate gear 12c.
  • a gear pump 22 is provided on section 6a, suitably at the outer end of the latter, and is, via piping 23, 24 connected with the lower portion of housing 7 comprising an oil sump 25 near propeller shaft 4 and bearing 4a, and with manoeuvring central 15. From the manoeuvring central piping 16, 17 extends to annular chambers 18, 19 and clutches 13, 14.
  • a return conduit (not shown) extends to oil sump 25 for return of pressure fluid when the manoeuvring central is disengaged, or via pressure valves, respectively, when the manoeuvring central is engaged for forward or rearward motion of the craft, i.e. in one or the other direction of rotation of screw 5.
