Description of the Invention: [Technical Field] The present invention relates to a ship rudder according to the preamble of claim 1 [Prior Art] A rudder such as a full-floating rudder or balance with or without hinged fins Contour rudders are well known in many different embodiments. SUMMARY OF THE INVENTION The object of the present invention is to create a rudder that avoids the formation of 'erosion on the rudder due to cavitation, especially when used on a fast ship with a high stress propeller, and can reduce fuel consumption. . This object is achieved by a rudder of the type described in the preamble having the characteristics indicated in item 1 of the scope of the patent application. Therefore, according to the rudder of the first application of the patent scope, there are two superimposed rudder blade portions, and the rafters are offset from each other before the thrusters, so that one rafter is turned to the port side or to the starboard side, and the other rafter is biased. Move to the starboard or port side. The two side walls of the rudder blade converge into a terminal strip that turns away from the propeller. According to the invention, the advantages of such a rudder having two laterally inverted cross-sections, on the one hand, avoiding the formation of steam bubbles and, on the other hand, the erosion of the rudder, is due to the formation Rapid on-board cavitation in high-stress ii m devices. The special configuration of the rudder blade helps to reduce fuel consumption. In addition to the great protection against cavitations, the improvement of 1295982 is also effective. It can be achieved to prevent very large 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 to obtain two laterally inverted cross-sections of the two rudder blade portions. 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 a maximum profile thickness) and a The rear surface (which follows the front surface and tapers to the rear end strip) is formed, and therefore, the two front surface portions formed by extending one of the center lines in the longitudinal direction of the rudder blade have different sizes, making them larger The 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 contour The cross section is formed by a front surface (the front surface extends from the front rafter to the rear end strip and is tapered to the maximum contour thickness and is formed by following the surface of the front surface, thus extending one section in the longitudinal direction of the rudder blade The two front surface portions formed by the center line have different sizes such that the larger surface portion is located on the starboard side so that The small surface portion is located on the port side, so that the two surface portions formed by the center line in the rear region of the profile section are identical in configuration so that the raft blade portion of the upper rudder blade portion is associated with the thruster - 6- 1295982 The port side of the core line 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 profile section of the upper rudder blade section have edge regions (which have a flat surface) The route and the curved curved path), therefore, the two surface portions of the profile section of the upper rudder blade portion (they are turned away from the thruster) have tangentially extended edge regions, thus having an edge region (which has an arch shape) The surface portion of the curved path 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 planar path and a path with arched curvature), and therefore, the lower rudder The two surface portions of the profile section of the blade portion (which are turned away from the thruster) have tangentially extended edge regions Therefore, the surface portion having the edge region (the route having the arched curve) is located on the port side. [Embodiment] In the rudder configuration represented in Fig. 1, 1 1 0 represents the hull, and 1 20 is the rudder bucket. The bearing, 100 is a rudder blade and 140 is a rudder axle. The propeller 220 is coupled with the rudder blade 1 。. According to the 2A, 2B and 3, the rudder blade 100 has two superimposed rudder portions 10, 20. The front rafters 1, 1, 3 1 are rotated to the thrusters 220 in such a way as to offset each other such that one rafter 丨丨 is offset from the port BB and the other rafter 2 1 is offset to the starboard side SB. The two side wall faces l〇〇a, l〇〇b倂 of the 〇〇 are combined into a terminal strip 30 that is turned away from the propeller 220. 1295982 The upper and lower rudder blade portions of the rudder blade 100 are 1〇, 2 〇 configured as follows According to Fig. 4, the upper rudder blade portion 10 has a profile section 12 which is formed by the front surface 14 which extends from the front sill to the end strip 30 and which gradually expands to the maximum profile thickness 13. A rear surface 15 extends to the terminal strip 30, which tapers to the end strip 3 and follows the previous surface 14 . The front surface 14 is divided into two surface portions 14a, 14b having different sizes via a center line M1 extending in the longitudinal direction of the rudder blade 1 〇 . The larger surface portion 14a is located on the port side and the smaller surface portion 14b is rotated to the starboard side. The rear surface 15 is also divided into two surface portions 15a, 15b via a center line Μ1. Here, the two surface portions 15a, 15b have the same size and the same form. The surface portions 14a, 14b of the two thruster sides of the profile section 12 of the upper rudder blade portion 1 have an edge region 16, 16a having a planar path 16'a, whereby the contour section 12 of the upper rudder blade portion 10 is two The surfaces 15a, 15b are rotated away from the pusher 220 with a tangentially extending edge region 17,7 7 a. The surface portion 14b having the edge region 16a having a strong arcuate curved path 16'a is located on the starboard side. According to Fig. 5, the lower rudder blade portion 20 has a laterally inverted profile section 22. This profile section 22 extends from a surface and tapers from the front girders 2 1 to the terminal strips 30, i.e., becomes the largest profile thickness 23. A surface 25 extends to the terminal strip 30 and it tapers to the end strip 30 following the front surface 24. The front surface 24 is divided into two surface portions 24a, 24b having different sizes via a center line M2 extending in the longitudinal direction of the rudder blade 1 〇〇 1295982. The larger surface portion 24b is positioned on the starboard side and the smaller surface portion 24a is rotated to the port side. The rear surface 25 is also divided into two surface portions 2 5 a, 2 5 b via a center line Μ 2 . Here, the two surface sections 25a, 25b have the same size and the same form. The two thruster-side surface portions 24a, 24b of the profile section 22 of the lower rudder blade portion 20 have edge regions 26, 26a having a planar path 26' and a curved curved path 26'a, thus the lower rudder blade portion The two surfaces 25a, 25b of the profile section 22 of 20 rotate it away from the edge region 27, 27a of the pusher 220 having a tangential extension. The surface portion 24b having the edge region 26'a having a strong arcuate curved path 26'a is located on the port side. The configuration and arrangement of the two rudder blade portions 1 〇, 20 results in the truss 11 of the upper rudder blade portion 1 being united to the propeller 220 on the port side of the centerline M1 and the lower rudder blade The beam 21 of the portion 20 is located on the starboard side according to the center line M2, and therefore, the two rudder blade portions 10, 2 0 are gathered in the rear region of the rudder blade 1 0 0 to become a terminal strip 3 0 〇 according to the 2A 2B, 3D, 4 and 5, the two rudder blade portions 10, 20 of the rudder blade 100 having its profile sections 12, 22 are arranged in such a way as to thereby align the rudder blades Each of the side wall portions is rotated in the region of the strong arched curved paths 16'a and 26'a of the surface portions 14b and 24b on the starboard side and the port side to the surface of the starboard side profile section 1 2 The portion 14b and the surface 1529982 face portion 24b of the profile section 22 are rotated to the port side so that the stringers 1, 1 1 1 of the two rudder blade portions 1 〇 20 are located on the port side and the starboard side. However, the invention also includes a configuration of the rudder according to which the two rudder blade portions 1 , 20 having the rudder blades 1 其 of the profile sections 12, 22 are arranged in such a way as to align the rudder blades The side wall portions are such that they are located in the regions of the strongly arched curved paths 16a' and 26'a of the surface portions 14b and 24b on the port side and the starboard side, and thus the surface portion 14b of the profile section 12 is then rotated to The port portion 24b of the port side and profile section 22 is to the starboard side so that the beams 11, 2 1 of the two rudder blade portions 10, 20 are located on the starboard side and the port side. Regarding the rudder configuration represented in Figs. 6 to 8, 1 1 0 represents a hull, 120 is a rudder barrel bearing, 100 is a rudder blade, and 140 is a rudder shaft. A fin 135 is hinged to the rudder blade 100. The rudder blade 100 has a cylindrical recess 15 5 to accommodate the free end 1 20b of the rudder barrel bearing 120. The rudder barrel bearing 120 is configured as a cantilever branch having a central internal longitudinal bore 125. The seat is adapted to receive the rudder axle 140 of the rudder blade 100. Moreover, the rudder barrel bearing 120 configuration extends to the rudder blade 1A that is coupled to the rudder terminal. The rudder barrel bearing 120 has a bearing 150 in its bore 125 to support the rudder axle 140. Therefore, the bearing 150 is preferably placed in the lower end region 120b of the rudder barrel bearing 120. The rudder axle 140 is guided out of the rudder barrel bearing 120 by its terminal 140b having a portion 145. The free lower end of this extended portion 145 of the rudder axle 140 is fixedly coupled to the rudder blade 100 in the region 170, however, therefore, a connection -10- 1295982 is also provided herein, which can be replaced when the thruster shaft must be replaced The rudder blade 100 is released from the rudder shaft 140. The connection of the rudder axle 140 and the rudder blade 1〇〇 in the region 170 is located above the propeller shaft center 200 so that in order to disassemble the propeller shaft, only the rudder blade 1〇〇 must be removed from the rudder axle 140, and at the same time, On the other hand, it is not necessary to remove the snake shaft 140 from the rudder barrel bearing 120 because the free lower end 120b of the serpentine bearing 120 and the free lower end of the rudder shaft 140 are located above the center of the propeller shaft. With regard to this particular embodiment shown in Figures 1 to 3, only one single inner bearing 150 is provided for supporting the rudder axle 140 in the rudder barrel bearing 1 220; the additional rudder blade 100 is no longer required The bearing is on the outer wall of the rudder barrel bearing 120. In order to receive the free lower end 120b of the rudder barrel bearing 120, the rudder blade 100 has a cone or has a wall recess of 160. With respect to the rudder, the rudder barrel bearing 1 20 is designed as a cantilever mount having a central longitudinal bore 1 25 to accommodate the rudder axle 1 40 of the rudder blade 1 0 0 . Moreover, the rudder barrel bearing 120 configuration extends to the rudder blade 1〇〇. In addition, the rudder barrel bearing 1 20 is configured to extend to the rudder blade 100 coupled to the rudder shaft end and has a rudder shaft 150 in its bore 125 to support the rudder shaft 1 of the rudder barrel bearing 1 2 0 4 0. With respect to its free end 1 2 Ob, the rudder barrel bearing 120 extends in one of the recesses or cones 160 in the rudder blade 100, so that the rudder shaft 1 4 0 in its terminal region 1 4 Ob is a part 145 guides the rudder barrel bearing 120. The rudder axle M0 is a rudder blade 100 having a free end coupled 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 thruster shaft center 200. The inner bearing 150 is preferably placed in the terminal zone -11- 1295982 field 120b of the rudder barrel bearing 120. The invention is not limited to the specific embodiments described above and in the various figures. The difference in the arrangement of the bearings in the region of the rudder barrel bearing 120 and the rudder shaft 140 is within the scope of the present invention and the additional configuration of the cylindrical cone i 60 in the rudder blade 11.
