DESCRIPTION OF THE INVENTION: TECHNICAL FIELD The present invention relates to a ship rudder according to the preamble of claim 1 [Prior Art] Balance of a rudder such as a fully floating rudder or a fin with or without a hinge Contour rudders are well known in most different embodiments. SUMMARY OF THE INVENTION An object of the present invention is to create a rudder that avoids erosion due to cavitation and rudder, especially when used on a fast ship with high stress propellers, and can reduce fuel consumption. This object is achieved by a rudder of the type described in the preamble having the characteristics indicated in items 1 and 2 of the scope of the patent application. Thus, according to the second aspect of the patent application, the rudder according to the invention has a rudder blade (having two superimposed rudder blade portions), the front rafter (rotating to the propeller) in such a manner that one is offset to the other One causes a string to rotate the book on the port side or to the starboard side, and the other string is offset to the starboard or port side, so that the two side walls of the rudder blade converge into a terminal strip that turns away from the thruster. An advantage of such a rudder according to the invention having a profile cross section of a combination of two lateral inversions is that, on the one hand, avoiding steam bubble formation and, on the other hand, avoiding erosion on the rudder due to air bubbles The phenomenon is shaped and it appears on fast boats with high stress propellers. The special configuration of the rudder blade helps to reduce fuel consumption. In addition to the protection against cavitation, the 200535049 protection is also improved. Achieve great savings in weight. Due to the fact that the purlins of the two rudder blade sections are offset from each other such that the purlins of the upper rudder blade segment are set to the port and the lower rudder blade segments are set to the starboard or the upper rudder blade segment Set to the starboard side and set the purlins of the lower rudder blade segments to the port side, each obtaining two laterally inverted profile sections of the two rudder blade sections'. According to a second aspect of the patent application, in accordance with a further configuration of the invention, means for providing a rudder associated with its rudder axle in the rudder trunking channel bearing is provided. Also, with regard to this configuration, the rudder blade has two superimposed portions such that its front rafter (turning to the thruster) is offset in such a manner as to adjust one rafter to the port side and adjust the other rafter To the right limb, therefore, the two side wall faces of the rudder blade converge into a terminal strip that turns away from the propeller and, therefore, is a cantilever bearing that has a central longitudinal bore to accommodate the rudder axle of the rudder blade' And configured to extend into the rudder blade that is coupled to the rudder shaft end. Therefore, in order to support the rudder axle, a bearing is placed in the internal longitudinal bore of the rudder trunk passage bearing and extends into the rudder blade along with its free end. a recess, a cone or the like, whereby the rudder shaft in its terminal region is guided out of the rudder trunk passage bearing in one portion and connected to the terminal having the rudder blade, and thus the bearing Provided between the rudder blade and the rudder trunk channel bearing and thus the connection between the rudder axle and the rudder blade is located above the center of the propeller shaft, so the inner bearing of the bearing of the rudder axle is placed on the rudder trunk channel bearing In the terminal area of the rudder wall channel bearing. Advantages arising from such a rudder constructed in accordance with the present invention (with respect to the rudder, the rudder shaft is supported by a bearing in the end region of the rudder trunking bearing -6-200535049.) Thus, the rudder axle and the rudder blade The connection is located above the center of the propeller shaft and does not require an additional bearing for the rudder blade on the outer wall surface of the rudder trunking bearing.) In order to replace the propeller shaft, it is no longer necessary to remove the rudder blade. The rudder axle is withdrawn from the rudder trunk channel bearing because the connection between the rudder axle and the rudder blade is above the center of the propeller shaft. In addition to this advantage, the rudder blade of the rudder can have an extremely slim profile. A further advantageous configuration of the invention is the subject matter of each of the dependent claims. An advantageous embodiment of the invention provides that the upper rudder blade portion of the rudder blade has a contoured section which is formed by a front surface (which extends from the front rafter to the rear end _ strip and which tapers to the maximum rim thickness) And a rear surface (which follows the front surface and tapers to the rear end strip) to be formed, so that the two front surface portions formed by extending one of the center lines in the longitudinal direction of the rudder blade have different sizes, so that The large surface portion is on the port side and the smaller surface portion is on the starboard side, so the two surface portions formed by the center line in the rear region of the profile section are identical in configuration and the lower rudder blade portion of the rudder blade has A profile section is formed by a front surface (the front surface extends from the front rafter to the rear end strip and is tapered to a maximum profile thickness and is formed by following the surface of the front surface, thus extending through the longitudinal direction of the rudder blade The two front surface portions formed by one of the center lines have different sizes such that the larger surface portion is located on the starboard side and is smaller The surface portion is located on the port side, so that the two surface portions formed via the centerline in the rear region of the profile section are identical in configuration such that the rafter portion of the upper rudder blade portion is associated with the thruster at the centerline 200535049 The port side and the stringer of the lower rudder blade portion are located on the starboard side of the centerline. The surface portions of the two thruster sides of the contour section of the upper rudder blade portion have edge regions (which have a plane curved course and have an arch The curved course of the curve), therefore, the two surface portions of the contour section of the upper rudder blade portion (they are turned away from the thruster) have tangentially extending edge regions, thus having an edge region (which has an arcuate curved course) The surface portion is located on the starboard side. The surface portions of the two thruster sides of the profile section of the lower rudder blade portion have edge regions (which have a plane of curved curvature and a course with arched curvature), and therefore, the contour of the lower rudder blade portion The two surface portions of the section (they turn away from the thruster) have a tangential extension The area, thus the surface portion having the edge region (the route having the arched curvature) is located on the port side.

The rudder shaft 140 is guided out of the terminal 14 〇b of the portion 145 to the rudder trunk channel bearing 120. This extension of the rudder axle 140 The free lower terminal of portion 145 is fixedly coupled to the rudder blade 1 in region 170, however, therefore, here also is provided in 200535049 For the connection, when the propeller shaft has to be replaced, it can release the rudder blade 1 自 from the rudder axle 40. The connection between the rudder axle 1 4 0 and the rudder blade 1 区域 in the region 1 7 位于 is at the center of the propeller shaft Above the 20,000, in order to disassemble the propeller shaft, it is only necessary to move the rudder blade 1 上 from the rudder shaft 1 400, and on the other hand, it is not necessary to move the rudder from the rudder trunk channel bearing 120. The shaft 14〇 is located above the center of the propeller shaft because the free end of the rudder trunk channel bearing 1 2 0 and the free end of the rudder axle 1 4 0 are located above the center of the propeller shaft. In this embodiment, only one single inner bearing 1 5 设置 is provided for supporting the rudder axle 1 4 0 of the rudder trunking channel bearing 1 2 0; the additional bearing of the rudder blade 1 不再 is no longer required at the rudder enclosure On the outer wall of the channel bearing 1 2.0. In order to receive the free lower end 120b of the rudder trunk channel bearing 120, the rudder blade 100 has a cone or a wall recess of 160. With respect to the rudder, the rudder wall channel bearing 1 20 is designed as a cantilever support having a central longitudinal bore 1 2 5 to accommodate the rudder blade 1 The rudder axle of the crucible is 140. Further, the rudder trunk channel bearing 1 2 0 configuration is extended to the rudder blade 100. In addition, the rudder trunk channel bearing 1 2 0 configuration is extended to the rudder axle The rudder blade 1 连接 connected to the terminal has a rudder axle 150 in its inner bore 1 2 5 so as to support the rudder axle 1 40 in the rudder trunking channel bearing 1 2 0. With respect to its free end 120b, The rudder trunk channel bearing 120 extends in one of the recesses or cones 160 in the rudder blade 100, thereby guiding the rudder axle 1404 in its terminal region 140b to the rudder trunk channel with a portion 1 4 5 Bearing 1 2 0. The rudder axle 140 is a rudder blade 100 having a free end connected to the extension portion 145. Therefore, the connection of the rudder axle 140 to the rudder blade 100 in the region 170 is located above the center of the propeller shaft 200. . The inner bearing 150 is preferably placed in the terminal region 1 2 0 b of the rudder 200535049 surrounding wall bearing 1 2 0. The invention is not limited to the specific embodiments described above and in the various figures. The configuration of the bearing in the region of the rudder trunking channel bearing 1 2 0 and the rudder axle 1 40 is within the scope of the present invention and the additional configuration of the cylindrical cone 160 in the rudder blade 1 1 . The rudder device constructed in accordance with the present invention can be used in ships as well as in floating platforms or similar objects and the like.
