Description

The The invention relates to rudders, rudder nozzles and Rudderpropeller with preferably only upper pivot bearing for watercraft, which to increase the reliability and the rudder effect with rudder or nozzle fins or rudder propeller are equipped.

It There are already various solutions of rowing fins or rudder nozzles with rudder fins, various rudder and nozzle bearings and operating mechanisms the fins.

Among the best known is the "Becker KSR rudder", as the DE-Z: ship & port, H.12 / 1978, S.1147 / 1148 and the DE-OS 38 14 943 can be removed in which for the upper bearing of the rudder a ship-solid rudder post with hollow bore in the rudder blade absorbs the forces acting on the rudder and moments, so that the rudder stock is largely relieved and has almost exclusively transmit the torque of the rudder drive.

The However, in terms of load advantageous solution requires in comparison with upper and lower mounted rudders at least in the area of the rudder protruding rudder post a thicker profile with the corresponding hydrodynamic disadvantages.

The known, the rudders or rudder nozzles downstream rigid so-called "stabilizing fins" shift mainly the Rudder force center to the rudder or nozzle rotation axis and stabilize course, but able they do not generally give up the separations at big Avoid rudder angles.

rudder or rudder nozzles increase with rotatable fins due to the better flow around In contrast, meaning the rudder effect at larger rudder angles. At the most frequent driving conditions are for price stabilization, however, only rudder angles of a few degrees needed for the rudder or nozzle fins are not required. With the practically executed oars and rudder nozzles with downstream fins also takes place the fins employment inevitably mechanically dependent from the movement of the main rotor or the rudder nozzle, from which e.g. in reverse maneuvers one unfavorable Fin position results.

The solutions made so far, as in the DE 31 01042 and the DE 31 50 992 They try to overcome these drawbacks, but they require complicated mechanisms in the rudder blade, which are difficult to accommodate, monitor and repair in the available space. In addition, they are not applicable to rudder nozzles with fin control.

Also in the DE 34 90 665 proposed solution of a separate drive of rotors on the rudder blade is not suitable because of the complicated transmission also required for the solution of the following object.

A simple and reliable, directly controlled actuation the rudder or rudder fins, sufficient for usual course corrections, gives not so far.

It The aim of the invention is to improve ship safety and economy with ship rudder, rudder nozzles and Rudderpropeller with a reliable one Rudder, rudder nozzle or Rudderpropellerlagerung with low height and low installation costs and a efektiven operation and Control the rudder or nozzle fins for the entire Create pitch range.

task The invention is, especially for one-sided above in or on hull mounted rudders with rudder fins and rudder nozzles with rotating fins, Saddle nozzle rudder or Rudderpropeller a reliable one-sided upper pivot bearing for the main tax and Auxiliary control with independent and / or coupling operation to create by separate, even combined rowing machines.

According to the invention Task by a combined hollow column plate storage of the main rudder or the rudder nozzle with in the hollow column integrated fin rudder stock in conjunction with stand-alone or coupled rowing machines solved.

The combined hollow-column plate bearing of the rudder or the rudder nozzle is located substantially within the hull, so that the compounds with the rudder or the rudder nozzle are on the strength side and hydrodynamically low gestaltbar. Compared to the conventional shaft bearing, it requires a lower overall height, which is particularly suitable for the one-sided upper bearing of rudders and rudder nozzles, can be assembled or welded on the ship without drilling operations, has both a reliable flange connection with the rudder or the rudder nozzle as well as recording options for the integrated directly or coupled operable fins oar shaft.

The inventive solution allows at the execution with direct independent activity the rudder or nozzle fins the fin movement without actuation of the principal controlling body. That has for small course corrections the advantage of a particularly sensitive control while maintaining the optimal propulsion position of the main controller, while saving energy for the main rotor in the stand-by mode.

at larger required Rudder angles and reverse maneuvers by the self-steering system both the main controlling organ and the rudder fin in the most effective job combination controlled.

The Invention will be explained in more detail below with reference to exemplary embodiments. It demonstrate:

1a a high-lift rudder 9 with beam twist profiles 14 and hub vortex entanglement 15 , with combined rowing column-rowing-bed storage 3 and controllable rudder fin 11 with fin rudder shaft 16 and fin drive 17 .

2 B using the example of a saddle rudder nozzle 10 , analogous to the rudder 9 , the fin making BB. or StB., with the Sattelruderdüse 10 in unchanged center or propulsion optimum position with no or slight fin adjustment for small course corrections,

2c the seat rudder nozzle 10 at full nozzle and fin rotation angles for forward and reverse maneuvers.
