t), that is, due to the combined rudder force acting on the tube bearing. The necessary cross-sectional area of the rudder post in the vicinity of the rudder bearing, the bearing dimensions, the rudder size in relation to the rudder post, and the rudder thickness are determined by the two-axis stress state together with the torque required for steering.

いうことは知られている。The skid rudder, which is mechanically suitable for the flow, and in particular the highly efficient skid rudder with additionally articulated leading and / or tracking wings, is located in the stern above the stern counter or above the flat bottom. It is also known to be mounted in a cast and / or welded rudder housed in a stern fin fixed to the hull.

収されるが、非常に大きな舵は異なる装着支持システム
を有する。In the case of a rudder with the lower jaw partly leaning forward, the bending moment is absorbed by the rudder post connected to the hull, but very large rudders have a different mounting support system.

するようになっている。In known lockable rudders, the hull is provided with a sleeve-like rudder, which receives a rudder post introduced into the rudder plate, and which is arranged at a distance. It contains a large number of horizontal webs, on which side armor plates are arranged, in which the rudder columns located inside the rudder plate are fixed by welded joints. The rudder post absorbs both bending moment and torque.

行容量を有する船に生じる。However, balancing rudder and skid rudder bearings with fins are configured such that the bending moments resulting from the rudder rise to the rudder bearings and are supported by the rudder columns, which become very thick. Therefore, the thickness of the rudder post and the bearing dimensions limit the use of ski-shaped or balanced rudders with fins, and this limit arises on ships with an operating capacity of about 15,000 tonnes.

舵のために相対的に大きな舵取機が要求される。The separation of the biaxial stress states that occur in the rudder with the lower jaw partly protruding gives rise to hydrodynamically unfavorable asymmetric properties due to the upper fixed column and the gap effect created at the lower movable balancing surface. . Since the rudder moment is often significantly asymmetric due to the propeller swirl, a relatively large steering gear is required for steering.

いう不利益をこうむる。Displacement rudders with "heel" bearings suffer from the disadvantage that the wake distribution has an unfavorable effect on the propeller position and increases the resistance of the appendage.

能であるからである。Furthermore, in the case of the known rudder, it is not only necessary to remove the rudder plate from the rudder post for replacement of the propeller shaft, but instead, the rudder post is instead steered to allow free removal of the propeller shaft. Must be pulled out of the mouth or at least pulled up. The reason is that in many rudders, the rudder post extends down to the center line of the propeller shaft, and the propeller shaft can be replaced only when the rudder post is removed from the rudder post and the rudder post is removed. Because it is possible.

舵を構成することである。The problem of the invention in a rudder, in particular a balanced rudder having a single- or multi-piece skid-type rudder and fins, is that the special design of the rudder bearing causes the position of the rudder into the rudder bearing via the rudder post. Absorbs the bending moments initially introduced into the hull, and on the one hand greatly reduces the stresses on the rudder column in order to allow a simple structural connection of the resulting thin rudder column to the rudder, on the other hand The purpose is to enable steering with a small-sized steering gear and at the same time facilitate replacement of the propeller shaft. Another object of the present invention is to configure a rudder such that a propeller shaft can be easily attached and detached without removing a rudder column from a rudder port bearing.

In the rudder, to the rudder plate of the rudder post excluding the loading distance between the rudder plate and the rudder port bearing The connecting portion is disposed above the center line of the propeller shaft, and the rudder plate is provided with the rudder plate to simplify installation and removal of the rudder propeller shaft without removing the rudder post from the rudder port bearing. It is characterized by being detachably connected to a pillar.

軸受は厳しい曲げひずみと応力に最早さらされることは
ないので、軸受はより小型にし得る。An advantage gained through the rudder structure according to the invention is that, for a achievable rudder size, the application range of a skid rudder and a balancing rudder having split or non-split structure fins is considerably increased. This is accomplished by the separation of the biaxial stress states, wherein the bending moment absorbed by the rudder is sucked into the rudder and introduced into the hull. The torque for rudder drive is transmitted via a long rudder post. Therefore, if the surface dimensions of the rudder do not change, it is possible to use a thinner rudder with low resistance. Furthermore, the connection of the rudder to the rudder post is more favorable in terms of manufacturing costs and in terms of mounting. The proposed invention offers the possibility of reducing capital and installation costs in the context of smaller rudder bearings. As a result of bending moment and torque separation,
Since the bearing is no longer exposed to severe bending strains and stresses, the bearing can be smaller.

す必要は最早ないということである。Only the rudder post is mounted by the bearing in the end region of the rudder bearing, and the rudder post in the end region is partially led out of the rudder port, and that portion is fixedly connected to the rudder plate, The advantage of this is that the connection position of the rudder post to the rudder plate is above the centerline of the propeller shaft without requiring a separate bearing for the rudder plate on the outer wall surface of the rudder bearing, Since the connection between the rudder post and the rudder plate is above the center line of the propeller shaft, it is no longer necessary to pull out the rudder post from the rudder bearing after removing the rudder plate when replacing the propeller shaft. That is.
