【産業上の利用分野】[Industrial applications]

本考案は、船舶の航行を司る舵の取付け構造に関するものである。 The present invention relates to a structure for mounting a rudder that controls navigation of a ship.

【0002】[0002]

【従来の技術】[Prior art]

船舶を定期検査するにあたっては、船舶を入渠させて、その船底を盤木上に支 持した状態で、舵軸を船外に引き抜いて所定の検査が行なわれる。このため、舵 軸を舵取機から外して、船外の下方へ抜き出せるような取付け構造としておくこ とが要求される。 When conducting regular inspections of ships, the rudder axle is pulled out of the ship while the ship is docked and the bottom of the ship is supported on a board, and a prescribed inspection is performed. For this reason, it is required to remove the rudder axle from the steering gear and set it up so that it can be pulled out to the lower side of the ship.

【0003】 舵が、いわゆる吊り下げ形であって、しかも盤木の高さ、船体寸法が十分大き いものである場合は、この舵軸の船外下方への引き抜きを特別な考慮なしに行な えるが、舵の下端がピントルを介して船体構造物で支承している構造の場合や、 盤木の高さ、船体寸法が十分でない場合は、舵軸に舵をつけたままで舵軸を船外 下方へ抜き出すことができない。If the rudder is of the so-called hanging type and the height of the board and the size of the hull are sufficiently large, the rudder shaft can be pulled out to the lower side of the ship without any special consideration. However, if the lower end of the rudder is supported by a hull structure via a pintle, or if the height of the block and the size of the hull are not sufficient, the rudder shaft is left on the rudder shaft with the rudder attached to it. It cannot be pulled out downwards.

【0004】 このような場合の対策として、従来は、図6および図7に示すように、舵軸5 1の下端部および舵53の頂部にそれぞれ結合用フランジ52,55を設け、こ れらフランジ52,55をボルト・ナット54で結合する構造とし、船舶の定期 検査に際して、舵軸51を船外に抜き出す時には、まず、舵軸51からその上端 部に結合されている舵取機59を切り離すとともに、上記フランジ52,55の 結合を解除した上で、舵53をその下端部が船体構造物57に回転自在に支承さ れているピントル56とともに取り外し、この舵53の取り外しにより発生した 空間を利用して、舵軸51を船外下方に抜き出すような舵の取付け構造が採用さ れていた。As a countermeasure against such a case, conventionally, as shown in FIGS. 6 and 7, coupling flanges 52 and 55 are provided at the lower end of the rudder 51 and the top of the rudder 53, respectively. The flanges 52 and 55 are connected by bolts and nuts 54. When the rudder shaft 51 is pulled out of the ship during the regular inspection of the ship, first, the rudder 59 connected to the upper end of the rudder shaft 51 is removed. In addition to disconnecting the above, the flanges 52 and 55 are uncoupled, and then the rudder 53 is removed together with the pintle 56 whose lower end is rotatably supported by the hull structure 57. A rudder mounting structure was adopted in which the rudder shaft 51 was pulled out to the lower part of the ship by utilizing the.

【考案が解決しようとする課題】[Problems to be solved by the device]

しかし、上記したような従来の舵の取付け構造においては、フランジ52が強 度上、厚さおよび幅のかなり大きなものになり、また、舵53の頂部側にも、同 等の厚さと幅をもつフランジ55を設けなければならないため、そのフランジ結 合部が、船舶の航行中、水流に対してかなりの抵抗損失になるという問題があっ た。 However, in the conventional rudder mounting structure as described above, the flange 52 is considerably large in thickness and width due to its strength, and the same thickness and width are provided on the top side of the rudder 53. Since the flange 55 must be provided, there is a problem that the flange joint causes a considerable resistance loss to the water flow during the navigation of the ship.

【0006】 本考案は上記のような問題を解消するためになされたもので、船舶の航行中に 余分な抵抗損失を招くようなフランジ結合を採用することなく、舵軸を舵の頂部 に直接固定する簡単な構成としながら、舵軸の船外下方への抜き出しを容易に行 なうことができる舵の取付け構造を提供することを目的とする。The present invention has been made to solve the above-described problems, and the rudder shaft is directly attached to the top of the rudder without using a flange coupling that causes extra resistance loss during navigation of a ship. It is an object of the present invention to provide a rudder mounting structure that allows a rudder shaft to be easily pulled out to the lower side of a ship while having a simple structure for fixing.

【課題を解決するための手段】[Means for Solving the Problems]

上記目的を達成するために、本考案に係る舵の取付け構造は、舵を上部舵と下 部舵とに分割し、そのうち上部舵の頂端面の舵の回転中心線上を貫通させて該上 部舵の舵骨内に挿入させた舵軸の下端部を上記上部舵の舵骨に溶接固定する一方 、下部舵を上記舵の回転中心線上に沿って下方へ突出させたピントルを介して船 体構造物に回転自在に支承させとともに、上記上部舵の下端部と下部舵の上端部 とに水平あるいは垂直の合わせ面を形成し、この両合せ面を、舵の水平断面輪郭 表面から外方へ突出することのない結合手段を介して分離可能に結合することに より、上記上部舵と下部舵とで上下に連続した水平断面輪郭を有する一体の舵を 構成させるようにしたものである。 In order to achieve the above-mentioned object, the rudder mounting structure according to the present invention divides the rudder into an upper rudder and a lower rudder, and the upper rudder of the upper rudder is penetrated on the rotation center line of the upper rudder. The lower end of the rudder shaft inserted into the rudder of the rudder is welded and fixed to the rudder of the upper rudder, while the lower rudder is attached to the hull via a pintle protruding downward along the center line of rotation of the rudder. The structure is rotatably supported, and a horizontal or vertical mating surface is formed at the lower end of the upper rudder and the upper end of the lower rudder.These mating surfaces are directed outward from the horizontal cross-sectional contour surface of the rudder. The upper rudder and the lower rudder are integrally connected by a connecting means that does not project so that the upper rudder and the lower rudder form a single vertical rudder having a horizontal cross-sectional contour.

【0008】[0008]

【作用】[Action]

本考案の舵の取付け構造によれば、舵が上下に分割され、そのうち上部舵側に 舵軸を一体に溶接固定してあり、かつ、下部舵に対しては水平あるいは垂直の合 わせ面で舵の水平断面輪郭表面から外方へ突出することのない結合手段を介して 分離可能に結合しているので、従来必要としていた厚さおよび幅の大きいフラン ジ結合をなくすることが可能である。これによって、船舶の航行中の水流抵抗損 失を著しく減少させることができる。それでいて、上部舵と下部舵との結合を解 除して、下部舵を取り外すことによって、上部舵と一体の舵軸を船外の下方へ容 易に抜き出すことが可能である。 According to the rudder mounting structure of the present invention, the rudder is divided into upper and lower parts, the rudder shaft is integrally welded and fixed to the upper rudder side, and the lower rudder has a horizontal or vertical mating surface. Since it is separably connected to the rudder through the connecting means that does not project outward from the surface of the horizontal cross-sectional profile, it is possible to eliminate the flange connection, which was conventionally required to have a large thickness and width. . This can significantly reduce the loss of water resistance during the navigation of the vessel. Nevertheless, by removing the connection between the upper rudder and the lower rudder and removing the lower rudder, the rudder shaft integrated with the upper rudder can be easily pulled out below the outboard.

【実施例】【Example】

以下、本考案の実施例を図面に基づいて説明する。なお、本実施例では、舵の 底面において舵の回転中心を船体構造物で支承する構造の舵の場合について説明 する。 Embodiments of the present invention will be described below with reference to the drawings. In the present embodiment, the case of a rudder having a structure in which the center of rotation of the rudder is supported by the hull structure on the bottom surface of the rudder will be described.

【0010】 第1実施例; 図1は、本考案の第1実施例による舵の取付け構造を示す要部の側面図、図2 は図1の要部の拡大断面図、図3は図2のA−A線に沿った縦断面図である。こ れら各図において、1は舵軸であり、該舵軸1の頂端部2には舵取機3が結合さ れており、その軸線xを回転中心として回転自在とされているとともに、船体の 船尾底板貫通部4に装着したラジアル軸受5を通って下方に延出され、その下端 部6において舵7に一体に結合されている。First Embodiment; FIG. 1 is a side view of a main portion showing a rudder mounting structure according to a first embodiment of the present invention, FIG. 2 is an enlarged sectional view of the main portion of FIG. 1, and FIG. 3 is a vertical cross-sectional view taken along the line AA of FIG. In each of these drawings, reference numeral 1 denotes a rudder shaft, and a rudder 3 is connected to a top end portion 2 of the rudder shaft 1, and the rudder 3 is rotatable about its axis x, and It extends downward through a radial bearing 5 mounted on the stern bottom plate penetration portion 4 of the hull, and is integrally connected to a rudder 7 at a lower end portion 6 thereof.

【0011】 上部舵7は、上部舵8と下部舵9とに上下二分割されている。そのうち、上部 舵8は、図2に明示のように、舵骨10、舵板11、水流による揚力発生効果を 高めるように頂部において両舷側に張り出した頂端板12および下部舵9との結 合のために水平に設けた下面水平板13とからなり、回転中心線x上において、 上記舵軸1の下端部6を、頂端板12を貫通して舵骨10内に強度上必要とされ る長さだけ挿入し、その挿入された舵軸1の下端部6とそれに当接する舵骨10 との間を溶接固定している。The upper rudder 7 is vertically divided into an upper rudder 8 and a lower rudder 9. As shown in FIG. 2, the upper rudder 8 is connected to the rudder bone 10, the rudder blade 11, the top end plate 12 and the lower rudder 9 which are projected to both sides at the top so as to enhance the lift generation effect by the water flow. And a lower horizontal plate 13 provided horizontally for the purpose of strength in the rudder bone 10 through the lower end 6 of the rudder shaft 1 through the top end plate 12 on the rotation center line x. Only the length is inserted, and the lower end 6 of the inserted rudder shaft 1 and the rudder bone 10 abutting it are fixed by welding.

【0012】 一方、下部舵9は、舵骨15、舵板16、水流による揚力発生効果を高めるた めるように底部において両舷側に張り出した底端板17および上部舵8との結合 のために水平に設けた上面水平板18からなり、かつ、上記底端板17の底面の 回転中心線x上において、下方に向けてピントル19を突出させ、このピントル 19を、舵支承船体構造物20に設けたピントル受け21内に、回転自在に遊嵌 させ支承させている。On the other hand, the lower rudder 9 is connected to the rudder bone 15, the rudder blade 16, the bottom end plate 17 protruding to both port sides at the bottom so as to enhance the lift generating effect by the water flow, and the upper rudder 8. A top horizontal plate 18 horizontally provided on the bottom end plate 17, and a pintle 19 is projected downward on the rotation center line x of the bottom surface of the bottom end plate 17, and the pintle 19 is attached to the rudder bearing hull structure 20. It is rotatably loosely fitted and supported in a pintle receiver 21 provided on the.

【0013】 そして、上記上部舵8の下面水平板13と、下部舵9の上面水平板18とを図 3に明示するように、上下に重ね合わせた状態で、この上下の水平板13,18 同士を舵水平断面輪郭の内側において結合手段の一例であるボルト・ナット22 を介して分離可能に結合することにより、上部舵8と下部舵9とによって、上下 に連続した水平断面輪郭を有する一体の舵7を構成させている。Then, as shown in FIG. 3, the lower horizontal plate 13 of the upper rudder 8 and the upper horizontal plate 18 of the lower rudder 9 are piled up and down, and the upper and lower horizontal plates 13, 18 are stacked. The upper rudder 8 and the lower rudder 9 are connected to each other so as to be separable from each other inside the rudder horizontal cross-sectional contour via bolts and nuts 22 which are an example of a connecting means, so that the upper rudder 8 and the lower rudder 9 have a continuous horizontal cross-sectional contour. Of the rudder 7 is configured.

【0014】 なお、上記下部舵9における舵板16には、上記ボルト・ナット22を挿入・ 離脱するために必要な開口23が形成されており、この開口23は、そのままに しておいても舵性能および水流抵抗にほとんど影響を及ぼすことはないが、該開 口23を図3に示すように舵表面輪郭に沿った舵板片24で覆うようにすれば、 舵性能、水流抵抗とともに、舵の上下分割による影響を全く受けないので、一層 好ましい。The rudder blade 16 of the lower rudder 9 is formed with an opening 23 for inserting and removing the bolt and nut 22, and the opening 23 may be left as it is. Although the rudder performance and the water flow resistance are hardly affected, if the opening 23 is covered with a rudder plate piece 24 along the rudder surface contour as shown in FIG. It is more preferable because it is not affected by the vertical division of the rudder.

【0015】 また、上記上部舵8と下部舵9との分割比率は、船尾底板の貫通部4から舵軸 1の頂端部2までの長さ、船尾底板の貫通部4の穴径、ドックの船底支持盤木の 高さ、船体寸法、舵支承船体構造物20の寸法等によって個々に定められるが、 通常、上下の分割比率を2対1程度に設定すれば、目的を達することができる。 この比率が大きいほど上部舵8と下部舵9との結合部にかかる力は小さくなり、 結合部を小さくできる。The division ratio between the upper rudder 8 and the lower rudder 9 is determined by the length from the penetration portion 4 of the stern bottom plate to the top end 2 of the rudder shaft 1, the hole diameter of the penetration portion 4 of the stern bottom plate, and the dock Although it is individually determined by the height of the bottom support block, the size of the hull, the size of the rudder bearing hull structure 20, etc., normally, the purpose can be achieved by setting the upper and lower split ratios to about 2: 1. The larger this ratio, the smaller the force applied to the connecting portion between the upper rudder 8 and the lower rudder 9, and the smaller the connecting portion.

【0016】 次に、上記構成の舵の取付け構造における舵軸1の抜き出し要領を簡単に説明 する。 船舶の定期検査のための入渠により、舵軸1を船外の下方に抜き出すにあたっ ては、まず、上部舵8と下部舵9とを結合するボルト・ナット22を外すととも に、舵軸1の頂端部2と舵取機3との結合を解除する。次に、舵軸1と上部舵8 との結合体を、下部舵9から下方へ突出のピントル19がピントル受け21から 外れるように持ち上げ、これにより、下部舵9を舵支承船体構造物20から取り 外す。この取り外しにより生じた空間を利用して、舵軸1と上部舵8の結合体を 舵支承船体構造物20の上面に達するまで下げることにより、舵軸1の頂端部2 が船尾底板の貫通部4より下方へ抜け出ることになり、この状態で舵軸1と上部 舵8の結合体を後方へ移動させることにより、舵軸1および上部舵8の船外下方 への抜き出しが完了する。Next, the procedure for extracting the rudder shaft 1 in the rudder mounting structure having the above configuration will be briefly described. When the rudderstock 1 is pulled out of the outboard of the ship by a dock for regular inspection of the ship, first, the bolts and nuts 22 that connect the upper rudder 8 and the lower rudder 9 are removed, and the rudder shaft 1 is removed. The connection between the top end portion 2 of 1 and the steering gear 3 is released. Next, the combined body of the rudder axle 1 and the upper rudder 8 is lifted so that the pintle 19 projecting downward from the lower rudder 9 is removed from the pintle receiver 21, whereby the lower rudder 9 is removed from the rudder bearing hull structure 20. Remove. Using the space generated by this removal, the combined body of the rudder axle 1 and the upper rudder 8 is lowered until it reaches the upper surface of the rudder bearing hull structure 20, so that the top end 2 of the rudder axle 1 penetrates the stern bottom plate. 4, the rudder axle 1 and the upper rudder 8 are moved rearward in this state, and the pulling out of the rudder axle 1 and the upper rudder 8 to the lower side of the outboard is completed.

【0017】 なお、上部舵8と下部舵9とを結合するボルト・ナット22を先に外す代わり に、ピントル19をピントル受け21から抜き出し、しかる後に、ボルト・ナッ ト22を外して下部舵9を取り外し、以降、上記と同様の手順で舵軸1と上部舵 8の結合体を船外に抜き出すようにしてもよい。Instead of first removing the bolts and nuts 22 that connect the upper rudder 8 and the lower rudder 9, the pintle 19 is pulled out from the pintle receiver 21, and then the bolts and nuts 22 are removed to remove the lower rudder 9. After that, the combination of the rudder shaft 1 and the upper rudder 8 may be pulled out of the ship by the same procedure as above.

【0018】 第2実施例; 上記した第1実施例において、上部舵8と下部舵9の結合を水平板13,18 による水平面での重ね合せによって行なうようにする代わりに、図4および図5 に示すように、上部舵8の下面には、下方に向かって垂直で、舵水平断面長手方 向に亘って上部垂直板24を固定する一方、下部舵9の上面には、上方に向かっ て垂直で、舵水平断面長手方向に亘って下部垂直板25を固定し、これら両垂直 板24,25を垂直面内で重ね合わせたとき、上部舵8と下部舵9のそれぞれの 表面輪郭が連続するようにし、この両垂直板24,25を舵の水平断面輪郭の内 側において、ボルト・ナット26を介して結合するようにしたものである。Second Embodiment: Instead of the above-described first embodiment, in which the upper rudder 8 and the lower rudder 9 are connected to each other by overlapping the horizontal plates 13 and 18 in a horizontal plane, FIG. 4 and FIG. As shown in FIG. 5, the upper vertical plate 24 is fixed to the lower surface of the upper rudder 8 vertically downward and over the longitudinal direction of the rudder horizontal section, while the upper surface of the lower rudder 9 is directed upward. Vertically, the lower vertical plate 25 is fixed along the longitudinal direction of the rudder horizontal section, and when these two vertical plates 24, 25 are overlapped in the vertical plane, the surface contours of the upper rudder 8 and the lower rudder 9 are continuous. The vertical plates 24 and 25 are connected to each other via bolts and nuts 26 on the inner side of the horizontal cross-sectional profile of the rudder.

【0019】 なお、この第2実施例において、上記ボルト・ナット26の結合のために設け られた舵板上の開口の処置については、上記第1実施例の場合と同様であるため に、説明を省略する。In the second embodiment, the treatment of the opening on the rudder plate provided for connecting the bolts and nuts 26 is the same as that in the first embodiment, and therefore will be described. Is omitted.

【0020】 第3実施例; 図示は省略するが、第1実施例において、上部舵8と下部舵9の結合を水平板 13,18の重ね合わせによって行なうようにする代わりに、上部舵8側の下面 水平板13の下面に、舵水平断面長手方向に亘って突起体を設ける一方、下部舵 9の上面水平板18の上面に、上記突起体が嵌合するリセスを設け、この突起体 とリセスとを嵌合させて上下の水平板18,13を結合することにより、上部舵 8と下部舵9との結合をより強固にするとともに、これら上下部舵8,9の間の 位置決めを容易にすることができる。なお、この第3実施例において、上記突起 体とリセスとの上下位置関係を逆にしても、同様な効果を奏する。Third Embodiment: Although not shown, in the first embodiment, instead of connecting the upper rudder 8 and the lower rudder 9 by overlapping the horizontal plates 13 and 18, the upper rudder 8 side The lower surface of the horizontal plate 13 is provided with a projection over the longitudinal direction of the rudder horizontal section, while the upper surface of the upper horizontal plate 18 of the lower rudder 9 is provided with a recess into which the projection is fitted. By fitting the recesses and connecting the upper and lower horizontal plates 18 and 13, the upper rudder 8 and the lower rudder 9 are more firmly connected and the upper and lower rudders 8 and 9 can be easily positioned. Can be In the third embodiment, the same effect can be obtained even if the vertical positional relationship between the protrusion and the recess is reversed.

【0021】 また、上記第2実施例を示す図4および図5のように、舵7の下面を舵支承船 体構造物20で支承しない、いわゆる吊り下げ形の舵であっても、舵を上下に分 割する構成とすることにより、舵軸の船体下方への抜き出しを容易にすることが できるものである。Further, as shown in FIGS. 4 and 5 showing the second embodiment, the so-called hanging type rudder in which the lower surface of the rudder 7 is not supported by the rudder bearing hull structure 20 By using a structure in which the rudder shaft is divided into upper and lower parts, it is possible to easily pull out the rudder axle below the hull.

【考案の効果】[Effect of device]

以上のように、本考案によれば、船舶が定期検査などのために入渠した時の舵 軸の船外抜き出しを容易にする対策として、従来採用されていた構成、つまり、 舵軸の下端および舵頂部にそれぞれ厚さと幅の大きいフランジを設けて、これら フランジ同志の結合をなくすることができるので、船舶の航行中の水流抵抗損失 を著しく減少させることができるという顕著な効果を奏する。それでいて、上部 舵と下部舵との結合を解除して、下部舵を取り外すことによって、上部舵と一体 の舵軸を船外の下方へ容易に抜き出すことができ、所定の定期検査などを能率よ く実行することができる。 As described above, according to the present invention, as a measure for facilitating the pulling out of the rudder axle when the ship is docked for periodic inspection, etc., the configuration conventionally adopted, that is, the lower end of the rudder axle and the Since flanges with large thickness and width are provided on the rudder top to eliminate the connection between these flanges, the water flow resistance loss during navigation of the ship can be significantly reduced. Even so, by removing the connection between the upper rudder and the lower rudder and removing the lower rudder, the rudder shaft integrated with the upper rudder can be easily pulled out to the lower side of the outboard, making it possible to perform predetermined periodic inspections efficiently. Can be carried out.

【0023】 また、従来の構成では、舵頂端部での舵軸との結合といったように、最も結合 強度を大きくしなければならない部位での結合であるのに対して、本考案の構成 では、上下に分割された上部舵と下部舵との結合といったように、結合強度が小 さくてすむ部位での結合であるため、結合部を従来よりも小型で簡単にすること ができるという効果も奏する。Further, in the conventional configuration, the connection is made at the portion where the connection strength should be maximized, such as the connection with the rudder shaft at the rudder tip end, whereas in the configuration of the present invention, Since it is a connection at a part that requires a small connection strength, such as an upper and lower rudder that is divided into upper and lower parts, there is also an effect that the connecting part can be smaller and simpler than before. .

According to the above, the rudder mounting structure is characterized in that the upper rudder and the lower rudder constitute an integrated rudder having a horizontal cross-sectional contour that is vertically continuous.
