Definitions

  • the invention relates to an adjusting device for adjusting the pitch of propeller blades which are rotatably mounted in the hub of an adjusting propeller of watercraft and which can be actuated by a linkage, the linkage being arranged by means of an adjusting member which is arranged in a non-rotating manner on the outflow side of the hub of the adjusting propeller and forms part of the adjusting device can be actuated with the adjusting propeller rotating adjusting member.
  • Adjustment devices with which the pitch of the blades of an adjustable propeller are adjusted are known in various designs. They serve on the one hand to better utilize the power installed in a watercraft and on the other hand to facilitate maneuvering of the watercraft.
  • the pitch of the propeller blades can be adjusted manually or automatically, depending on the application, and the propeller blades can also be adjusted for reverse travel.
  • variable pitch propeller is driven by a motorized drive inside the watercraft bene shaft is driven
  • the propeller blades are adjusted in different ways. It is known to introduce a pressure fluid into the propeller hub and thus to act on a piston system arranged in the hub, by means of which the propeller blades are adjusted (US Pat. No. 2,931,443).
  • the non-rotating adjustment member is connected to an adjustment linkage which in turn is coupled to a linear motor arranged at a distance from the adjustment propeller.
  • the adjustment device according to the invention can be used according to the invention in a watercraft in such a way that the linear motor is arranged in the area inside or outside the hull of the watercraft.
  • the adjusting device for an adjustable propeller 1 with adjustable propeller blades 2 shown schematically in FIG. 1 has a propeller hub 4 driven by a drive shaft 3.
  • the drive shaft 3 is driven by a drive machine 5 and mounted in a schematically illustrated bearing 6.
  • the pitch of the propeller blades 2 is essentially adjusted by a mechanical linkage 7, the main part of which is a two-armed adjusting lever 8, the pivot axis 9 of which is pivotally supported in a support bearing 10.
  • the support bearing 10 is mounted either in a part supported on the watercraft or, if the variable-pitch propeller 1 is part of a pivotable steering rudder arrangement, in this rudder arrangement.
  • the adjusting lever 8 has an upper arm 11 and a lower arm 12, the upper arm 11 being coupled via a joint 13 to the bumper 14 of a linear motor 15 driven by a power source 16, while the lower arm 12 is coupled via a second joint 16 a non-rotating actuator 17 is coupled.
  • the non-rotating adjusting member 17 can be designed differently and can be, for example, a ring or a sleeve which carries a radiax bearing 18, which in turn is mounted in a rotating adjusting intermediate member 19. Adjustment rods 20 are coupled to the latter, which are guided in the propeller hub 4 and adjust the individual propeller blades 2 synchronously.
  • the transition from the non-rotating adjustment member 17 to the rotating adjustment intermediate member (19) can be implemented in a simple and space-saving manner.
  • the second joint 16 is also arranged on the adjusting member (17), the adjusting member (17) can be accommodated together with this joint in a light, aerodynamic hood (4 ') surrounding the hub 4 without requiring additional space.
  • the propeller 1 driven by the drive shaft 3 is arranged fixedly below the hull 25 of a watercraft, a hollow support body 21 being attached to the hull 25, at the lower end of which the propeller 1 is mounted.
  • a control rudder 22 is pivotably mounted on the hollow support body 21 on the outflow side by means of hinge joints 24, while the mechanical linkage 7 is installed in the interior of the support body 21.
  • the reference symbols not described here correspond to those of FIG. 1.
  • the linear motor 15 here is a double-acting hydraulic cylinder, the piston rod of which forms the bumper 14 and is supported on the hollow support body 21 by means of a joint 23.
  • a hydraulic unit 26, which supplies pressure medium for actuating the adjusting device, is used to drive the linear motor 15.
  • the linear motor 15 which can also be an electrical or pneumatic unit, is mounted in the embodiment according to FIG. 2 below the fuselage 25 in the hollow support body 21, but it would also be possible to design the upper arm 11 of the adjusting lever 8 so that it protrudes into the watercraft so that the linear motor 15 could be arranged inside the hull 25.
  • FIGS. 3 and 4 show an adjusting device for adjusting the propeller blades 2 of an adjustable propeller 1 in connection with a sterndrive, in which the drive shaft 3 is not passed obliquely through the hull 25 of the watercraft, as shown in FIG. 2 is indicated. Rather, the drive shaft 3 is driven by the drive machine 5 via shafts 27, 28 and bevel gear 29, 30, the shafts 3, 27, 28 being arranged in a Z-shape.
  • the two bevel gears 29, 30 and the shafts 3, 28 are accommodated in a rudder arrangement 32 which is articulated to the fuselage 25 as a pivotable part via hinge joints 31 (only one visible in FIG. 3).
  • the entire adjustment device is also housed, of which the linear motor 15 with the bumper 14 and the mechanical linkage 7 are shown.
  • the reference numbers not explained here correspond to those of FIGS. 1 and 2.
  • the hydraulic motor 5 is a double-acting hydraulic cylinder, which is connected via lines 33, 34 to a power source 26 designed as a hydraulic unit.
  • the linear motor 15 is arranged on the outer wall of the rudder assembly 32, the mechanical linkage consisting of two adjusting levers 8 which are connected to one another by cross members 35, 36.
  • the double adjustment lever 8 has the same function as a simple adjustment lever.
  • the variable pitch propeller 1 with its drive shaft 3 is part of the actual rudder 37.
  • the outflow side of the variable pitch propeller 1 is free for the arrangement of the mechanical linkage 7 due to this arrangement Operation of the rudder 37 moves with it.
  • the power source 26 is conveniently housed in the hull 25 of the watercraft is, the power transmission parts 33, 34 must be resilient or articulated.
  • 3 shows that the combination of a mechanical linkage for the introduction of force into the propeller hub 4 and a linear motor, which is arranged at a distance from the propeller axis and is therefore largely free in its arrangement, is technically clean and also represents inexpensive solution.
  • the adjustment device described ensures that because of the arrangement of the linear motor 15 outside the area of the adjustment propeller and the space-saving force introduction of the adjustment means for the adjustment of the propeller blades 2 arranged on the outflow side, the propeller hub 4 can be dimensioned small, so that the mass of such Variable pitch propeller approaches the mass of a comparable propeller with fixed propeller blades.
