Abstract

Rudder has rudder blade (100) which comprises a fin and two superimposed section. The propeller (220) turned to front leading edge is transferred in such a manner that one leading edge transfers after the port side and the other leading edge transferred after the star board. The two side panel surfaces of the rudder blade run together in the propeller to turn away the trailing edge. The rudder spindle (140) in its end area with a section is led out from the rudder trunk bearing (120) and the end of this section is connected with the rudder blade. No bearing is provided between the rudder blade and the rudder trunk bearing. The connection of the rudder spindle with the rudder blade lies above the centre of the propeller shafts. The inner bearing for the bearing of the rudder spindle is arranged in the rudder trunk bearing at the end area of the rudder trunk bearing. An independent claim is also included for the rudder blade.

INSTRUCTIONS OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates to a ship rudder according to the preamble of claim 1 [prior art] rudder, such as a full floating rudder with or without hinged fins Or balanced contour rudders are well known in many different embodiments. [Summary of the Invention]

本發明的目的在創造一種舵，其能避免由於空泡現象形成，在舵上之侵蝕現象，尤其是當使用在具有高應力之推進器之快速船上時，且能減少燃料消耗。此目的以根據具有申請專利範圍第1項中所指示之特徵的序言中所述該型之舵予以達成。因此，根據申請專利範圍第1項之舵，具有兩個疊置之舵葉片部分，朝向推進器之前艏條係彼此偏移，使得一 Φ 個艏條朝向在左舷或朝向右舷，及另一艏條偏移至右舷或左舷，因此，舵葉片的兩側壁面會聚成爲一個背離推進器的終端條。根據本發明具有兩個側向倒轉之截面之外形所構成之此種舵的優點，一方面，避免蒸汽氣泡成形及，另一方面 ’避免舵上之侵蝕現象，其是由於在具有高應力之推進器的快速船上形成空泡現象。該舵葉片的特別構型有助於減少燃料消耗。除去甚大保護對抗空泡現象之外，亦有效率 1302894 的改進。可實現大幅減少重量。由於兩個舵葉片部分的艏條相互偏移，以致將上部舵葉片段的艏條設定至左舷及下部舵葉片段的艏條設定至右舷或將上部舵葉片段的艏條設定至右舷及將下部舵葉片段的艏條設定至左舷，各自獲得兩舵葉片部分的兩個側向倒轉之外形截面。SUMMARY OF THE INVENTION The object of the present invention is to create a rudder which avoids erosion on the rudder due to the formation of cavitation, especially when used on a fast ship with a high stress propeller, and which reduces fuel consumption. This object is achieved by a rudder of the type described in the preamble having the features 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 overlapping rudder blade portions which are offset from each other before the thruster, such that one Φ rafters are oriented on the port side or toward the starboard side, and the other 艏The strip is offset to the starboard or port side so that the two side walls of the rudder blade converge into a terminal strip that faces away from the propeller. The advantage of such a rudder having the shape of two laterally inverted cross-sections according to the invention, on the one hand, avoids steam bubble formation and, on the other hand, 'avoids erosion on the rudder, which is due to high stresses The cavities are formed on the fast ship of the propeller. The particular configuration of the rudder blade helps to reduce fuel consumption. In addition to the great protection against cavitations, there is also an improvement in efficiency 1302894. Achieve significant weight reduction. Since the rafters of the two rudder blade sections are offset from each other, the rafter of the upper rudder blade segment is set to the port side and the lower rudder blade section is set to the starboard side or the upper rudder blade section is set to the starboard side and The purlins of the lower rudder blade segments are set to the port side, each obtaining two laterally inverted outer cross-sections of the two rudder blade portions.

根據申請專利範圍第1項之本發明之另外構形提供與舵桶狀軸承中之其舵軸有關之舵的配置。亦，關於此構型，該舵葉片具有兩個疊置之部分，其朝向推進器之前艏條係偏移，使得一個艏條調整至左舷及另一艏條調整至右舷，因此，舵葉片的兩個側壁面會聚成一個背離推進器的終端條，因此，作爲懸臂支座的舵桶狀軸承係設有中央縱向孔以便容納舵葉片之舵軸，並予以構型延伸入與舵軸終端相連接之舵葉片中，因此，爲了支持舵軸，將一軸承置放在舵桶狀軸承的內部縱向孔中，其連同其自由端延伸入舵葉片中之壁凹、錐體或類似者中，因此，將舵軸在其終端區域以部分導引出舵桶狀軸承且以此部分的終端與舵葉片連接，因此，沒有軸承設置在舵葉片與舵桶狀軸承間且因此舵軸與舵葉片的連接位於推進器軸中央之上方，因此，將舵軸的軸承之內部軸承在舵桶狀軸承的終端區域中放置舵桶狀軸承中。自根據本發明所構型之此種舵所產生之優點（關於此舵，將舵軸藉軸承支持在舵桶狀軸承的終端區域中，因此，舵軸與舵葉片的連接位於推進器軸中央之上方，不需要 1302894 一另外軸承用於舵桶狀軸承的外壁面上之舵葉片上）在於 :爲了更換推進器軸，在取下舵葉片後，因爲舵軸與舵葉片的連接位於推進器軸中央之上方，不再需要將舵軸自舵桶狀軸承中抽出。除此優點外，舵的舵葉片可具有極爲纖細之輪廓。本發明的另外有利之構型是申請專利範圍各附屬項的主題。本發明的一個有利構型提供：舵葉片的上部舵葉片部 ® 分具有一輪廓截面，其係由一前表面（其自前艏條延伸至後終端條，且其漸擴大至最大之輪廓厚度）以及一後表面（其接著前表面且漸縮小至後端條）予以形成，因此，以舵葉片的縱方向延伸之中心線所形成之兩個前表面部分具有不同大小，其中較大之表面部分位於左航側而較小之表面部分位於右舷側，因此以在輪廓截面的後區域中之中心線所形成之兩個表面部分其構型相同及舵葉片的下部舵葉片部分具有一輪廓截面，其係由一前表面（此前表面自前艏 ® 條延伸至後終端條且漸擴大至最大之輪廓厚度）以及接著前表面之後表面予以形成，因此，以舵葉片的縱方向延伸之中心線所形成之兩個前表面部分具有不同大小，其中較大之表面部分位於右舷側而較小之表面部分位於左舷側，因此，以在輪廓截面的後區域中之中心線所形成之兩個表面部分其構型相同，使得與推進器相聯合之上部舵葉片部分的艏條位於中心線的左舷側上且下部舵葉片部分的艏條位於中心線的右舷側上。The additional configuration of the invention according to claim 1 of the patent application provides a configuration of the rudder associated with its rudder axle in the rudder barrel bearing. Also, with this configuration, the rudder blade has two overlapping portions that are offset from the stalk before the thruster, such that one rafter is adjusted to the port side and the other rafter is adjusted to the starboard side, thus the rudder blade The two side wall faces converge into a terminal strip facing away from the propeller. Therefore, the rudder barrel bearing as the cantilever bearing is provided with a central longitudinal hole for accommodating the rudder shaft of the rudder blade and configured to extend into the terminal end of the rudder shaft. In the connected rudder blade, therefore, in order to support the rudder axle, a bearing is placed in the internal longitudinal bore of the rudder barrel bearing, which, along with its free end, extends into a recess, cone or the like in the rudder blade, Therefore, the rudder shaft is partially guided out of the rudder barrel bearing in its terminal region and the terminal of this portion is connected to the rudder blade. Therefore, no bearing is disposed between the rudder blade and the rudder barrel bearing, and thus the rudder shaft and the rudder blade The connection is located above the center of the propeller shaft, so that the inner bearing of the bearing of the rudder shaft is placed in the rudder barrel bearing in the terminal region of the rudder barrel 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 the bearing in the terminal region of the rudder barrel bearing, and therefore the connection of the rudder shaft to the rudder blade is located in the center of the propeller shaft Above, there is no need for 1302894. Another bearing is used on the rudder blade on the outer wall surface of the rudder barrel bearing.) In order to replace the propeller shaft, after the rudder blade is removed, the connection between the rudder shaft and the rudder blade is located at the propeller. Above the center of the shaft, it is no longer necessary to extract the rudder shaft from the rudder barrel bearing. In addition to this advantage, the rudder blades 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 extending from the front raft to the rear end strip and which is gradually enlarged to the maximum contour thickness. And a rear surface (which is followed by the front surface and tapered to the rear end strip) is formed, so that the two front surface portions formed by the center line extending in the longitudinal direction of the rudder blade have different sizes, wherein the larger surface portion Located on the left side and the smaller surface portion is on the starboard side, so that the two surface portions formed by the center line in the rear region of the profile section have the same configuration and the lower rudder blade portion of the rudder blade has a contour section. It is formed by a front surface (the front surface extends from the front 艏® strip to the rear end strip and gradually enlarges to the maximum contour thickness) and then the surface of the front surface is formed, and thus is formed by the center line extending in the longitudinal direction of the rudder blade The two front surface portions have different sizes, wherein the larger surface portion is on the starboard side and the smaller surface portion is on the port side, therefore, The two surface portions formed by the center line in the rear region of the profile section are configured identically such that the rafter portion of the upper rudder blade portion is associated with the pusher on the port side of the centerline and the lower rudder blade portion The purlins are located on the starboard side of the centerline.
