Definitions

  • the invention relates to a variable pitch propeller for the drive of a watercraft, in which the propeller blades with their propeller hub are rotatably mounted in a housing fastened to a motor shaft and their pitch can be adjusted by a pivoting device which is operatively connected to an adjusting lever, and a drive for a Watercraft with this variable pitch propeller.
  • Variable pitch propellers are used to a considerable extent on watercraft, especially on ships. On the one hand, they make maneuvering easier and enable optimal propeller blade setting for the set speed and power of the propeller drive motor.
  • a power system is required to adjust the propeller blades.
  • a manual adjustment device can only be used with small adjustment propellers, since the adjustment forces can no longer be controlled manually with larger propellers.
  • Such an adjusting device essentially has a lever which can be actuated from the fuselage and which acts on an adjusting sleeve which is mounted on the outflow side of the propeller hub and on which an axial bearing is arranged which controls the transition to the rotating system, ie the rotating propeller blades.
  • a hydraulic adjustment drive is used throughout, in which e.g. a single hydraulic cylinder adjusts the propeller.
  • a pressure medium usually hydraulic oil, is required to adjust and hold the propeller blades, which is introduced into the hub via a supply line, while the used pressure medium is returned via a return line.
  • the transition from the stationary to the rotating part of the V ER- alternate propeller a delicate point represents, can occur at the leakage losses.
  • further leakage losses can also occur in the hub itself, which can no longer be collected and returned, but can escape into the water and contaminate it.
  • variable pitch propeller In the case of smaller ships and in particular motor boats, the variable pitch propeller has so far been largely unsuccessful because of the problems mentioned. In order for the fixed propellers used today to be replaced by variable pitch propellers, a number of conditions must be met. The mass of the variable pitch propeller, for example with regard to the hub diameter, and its weight should not differ significantly from the fixed propeller now used. The adjustment device must also be simpler be designed as the known hydraulic adjustment device.
  • variable pitch propeller of the type described at the beginning and a drive for a watercraft in such a way that the disadvantages mentioned are avoided and accordingly the variable pitch propeller is adapted to the dimensions and the weight of the fixed variable pitch propeller and a simple but reliable adjusting device is used can be. Furthermore, the adjustment device should not cause water pollution.
  • variable pitch of the initially described type is used, located at the on the periphery of an inner housing two or more holder, on which the P ropelrivabe female housing is removably secured by the holder.
  • the drive according to the invention is equipped with an adjustable propeller according to the invention, the adjusting lever for adjusting the pitch of the propeller blades being designed as a two-armed lever, one arm of which engages the axial bearing and the other arm is connected to a linear motor which is arranged at a distance from the adjustable propeller .
  • the E ndnabe 2 is designed as a splined shaft, on which an inner housing 3 is pushed and fastened with a nut 4.
  • the inner housing 3 is a cylindrical body which has a multi-spline sleeve 5 'from the inside out, which is embedded in an elastic sleeve 6, which in turn is surrounded by a metallic sleeve 7.
  • On the circumference of the support ring 9 holding rails 10 are arranged evenly distributed, which are designed according to FIG.
  • the module 12 comprises a propeller hub 13 with a control track 14 and an adjusting piston 15 with an adjusting pin 16 projecting into the control track 14.
  • the module 12 can be used unchanged, regardless of whether two, three or four propeller blades 17 are provided .
  • Only the inner housing 3 must have a number of rails 10 corresponding to the number of modules 12, the diameter of the support ring 9 also being able to be adapted to the respective embodiment as required.
  • the inner housing 3 and the modules 12 represent a space-saving lightweight construction, with which it is possible to maintain similar diameters of the propeller hub, which is common in propellers with fixed propeller blades are.
  • the hub construction consisting of the inner housing 3 and the modules 12 can be covered by a light outer hub 18, which, however, does not have to absorb large forces and can therefore be made from a light material, for example plastic.
  • the inner housing 3 has an end wall 19 on which the modules 12 are supported; the modules 12 are held in position by a screw 20.
  • the adjustment pistons 15 are connected at one end by an adjustment flange 21 by means of screws 22.
  • the adjusting flange 21 merges on the inside into a cylindrical connecting piece 23, which forms the seat for the outer ring of an axial rolling bearing 24, the inner ring of which is mounted on an adjusting sleeve 25.
  • the thrust roller bearing 24 is supported by rings 26, 27, e.g. Snap rings, held in their axial position, so that when a force is exerted on the adjusting sleeve 25, the adjusting pistons 15 are adjusted together.
  • the adjusting sleeve 25 has two tabs 28 with bores, between which a flat bar 29 is pivotally mounted by means of a bolt 30.
  • the flat bar 29 is part of an adjusting lever 31, the arrangement of which will be described with reference to FIG. 3.
  • the interior of the hub formed from the inner housing 3 and the modules 12 has various free spaces that can be used to discharge the engine gases from the engine.
  • the inner housing has a further sleeve 32, see FIG. 2.
  • An end cap is not required 33, with which the hub is otherwise closed.
  • the adjusting piston 15 is guided in two pipe sockets 34, 35, which form part of the housing 11 and are integrally connected to a hub cylinder 36.
  • the housing 11 accordingly consists of the hub cylinder 36, which has an inner collar 37, and the two pipe sockets 34, 35, on which of which a guide web 38 is formed on the motor shaft side, which is profiled in such a way that it fits onto the holding rails 10 of the supporting ring 9 can be postponed.
  • the holding rails 10 and the guides 38 form a positive, play-free connection.
  • the propeller hub 13 is connected to the foot 40 of the propeller blade 17 by means of screws 39 and is guided both axially and radially on the inner collar 37 of the hub cylinder 36. Since during the adjustment of the propeller blades 17 ropellantabe the P 13 moves sliding on the inner collar 37, the contacting surfaces may be coated with a sliding material. So that the propeller hub 13 and the adjusting piston 15 take up little space, a recess 41 is provided in the center of the adjusting piston, into which the propeller hub 13 protrudes and receives the adjusting pin 16 with its control path 14. When installing a propeller blade 17 in the modules 12, the propeller blade is first screwed to the propeller hub 13 in the hub cylinder 36.
  • a semicircular diagonal recess is provided in the propeller hub 13 (not shown), which is rotated for the assembly of the adjusting piston until the recess is aligned with the pipe socket 34, 35, whereupon the Adjusting piston 15 can be inserted.
  • Connection Send the propeller blade 17 is rotated until the adjustment pin 16 can be inserted into the control path 14.
  • elastic sealing rings 42, 43 for example O-rings, are arranged at its ends, which seals the space formed by the recess 41, which is filled with a lubricant, to the outside.
  • the seal to the outside at the foot 40 of the propeller blade is carried out on the contact surface on the inner collar 37 and by sealing the screw 39, so that a completely closed space is provided, through which the lubrication of the sliding surfaces in the region of the inner collar 37 is ensured.
  • FIG. 3 shows a complete drive for a watercraft with an adjustable propeller according to FIGS. 1 and 2.
  • the variable pitch propeller is driven by a motor M, which is shown schematically in the hull of the watercraft 50, via a so-called Z drive.
  • the motor shaft 1 is not carried out obliquely through the fuselage, but the torque is transmitted to the motor shaft 1 via shafts 51, 52 and through bevel gear 53, 54. 3, the shafts 1, 51, 52 form an approximate Z.
  • the variable pitch propeller is located together with the shafts 1, 52 in a rudder member 56 which can be pivoted about a vertical axis 31 at the end of the fuselage.
  • the member 56 consists of several rudder parts , a housing and a bearing for the motor shaft 1 (not shown).
  • the adjustment device for the adjustment of the propeller blades 17 comprises a linear motor 57, e.g. a hydraulic cylinder, the piston rod 58 of which is articulated via an adjusting screw 59 on a swivel joint 60 of the actuating lever 31.
  • the actuating lever 31 is designed as a two-armed lever with an axis of rotation 61, one arm 62 of which engages the adjusting sleeve 25 and the other arm 63 is connected to the linear motor 57 via the joint 60.
  • the linear motor 57 is expediently installed in the rudder member 56, but it can also be arranged on one side of this member, in which case precautions must be taken to obtain the necessary symmetry for the power transmission.
  • the linear motor is supplied with the necessary energy by a power source 64 via lines 65.
  • the linear motor 57 can also be arranged in the hull of the watercraft 50. In this case, a corresponding transmission linkage is to be provided, which acts on the joint 60 of the actuating lever 31.
  • the variable pitch propeller need not be installed in the rudder 56, but can also be permanently attached to the fuselage. In this case, the connection between the linear motor 57 and the actuating lever 31 is particularly simple. It is essential to completely detach the known hydraulic adjustment devices from the propeller hub, so that no complex guidance of the pressure medium is required. Nevertheless, the adjustment of the propeller blades 17 can be optimally solved with the adjustment system described, since the adjustment mechanism built into the modules 12 is optimally protected and also lubricated.
  • the transition of the adjustment movement from the control lever 31 to the rotating parts of the variable pitch propeller is expediently carried out on the A b flow side, since the motor shaft 1 does not have to be taken into account here, but the adjusting lever 31 could also be arranged on the upstream side without the conditions changing fundamentally.
  • the linear motor 57 is arranged away from the adjustable propeller and the propeller is adjusted via a lever linkage. If a double-acting hydraulic cylinder is used as the linear motor 57, sufficiently large adjustment forces with which the preselected propeller settings can also be maintained, for example in the event of vibrations, external contact or the like, can be generated.
  • the desired pitch of the propeller blades can be controlled quickly and precisely.
  • the housing 11 can be a cast piece of metal, for example made of light metal, while the propeller hub 13 and the adjusting piston can be made of steel, for example.
