Description

本発明は、例えば船舶の運航の制御や、海底油田掘削装置を海上の定点に保持するために、船舶に対して任意の方向に推力を与える旋回式プロペラ装置に関する。   The present invention relates to a swivel type propeller device that applies thrust in an arbitrary direction to a ship, for example, in order to control the operation of the ship or hold a subsea oil field drilling device at a fixed point on the sea.

従来、例えば船舶の運航の制御や、海底油田掘削装置を海上の定点に保持する目的で、浮体に対して任意の方向に推力を与える旋回式プロペラ装置がある。   2. Description of the Related Art Conventionally, there is a swivel type propeller device that applies thrust to a floating body in an arbitrary direction for the purpose of, for example, controlling the operation of a ship or holding a subsea oil field drilling device at a fixed point on the sea.

このような旋回式プロペラ装置は、旋回可能な垂直筒型のケースの中にある駆動伝達軸の下部に一個の傘歯車（ベベルギア）等の回転軸の方向を変えるドライブギアを設けてある。そして、その一個のドライブギアを、プロペラに固着する水平軸に固着したドリブンギアに噛合わせて駆動されていた（例えば、特許文献１参照）。特許文献１のような旋回式プロペラ装置をアジマススラスターという。   Such a swivel type propeller device is provided with a drive gear for changing the direction of a rotating shaft such as one bevel gear (bevel gear) under a drive transmission shaft in a swivelable vertical cylindrical case. The one drive gear is driven by meshing with a driven gear fixed to a horizontal shaft fixed to the propeller (see, for example, Patent Document 1). A swivel type propeller device as in Patent Document 1 is called an azimuth thruster.

一般に、旋回式プロペラ装置では、垂直軸の下端に固着した駆動用傘歯車で水平に配置されたプロペラ軸に固着した被駆動傘歯車を駆動してプロペラに回転力を伝えている。その結果、プロペラ軸を支えるケースには垂直軸を駆動するトルクと同じ値の反力が発生していた。当該反力に対してはケースの強度と剛性を十分に高くすることで対応することができる。   In general, in a swivel type propeller device, a driven bevel gear fixed to a propeller shaft disposed horizontally is driven by a driving bevel gear fixed to a lower end of a vertical shaft to transmit a rotational force to the propeller. As a result, the reaction force having the same value as the torque for driving the vertical shaft was generated in the case supporting the propeller shaft. The reaction force can be dealt with by sufficiently increasing the strength and rigidity of the case.

特許第２６２８８７０号公報Japanese Patent No. 2628870

上述のアジマススラスターにおいては、プロペラの回転軸を旋回させる場合に、上記反力に対抗してケースを旋回させなければならないが、この旋回させるためのトルクは極めて大きい。また、旋回動作を行わないときにおいても、一定角度に停止させなければならない。   In the azimuth thruster described above, when the propeller's rotating shaft is turned, the case must be turned against the reaction force, but the torque for turning is extremely large. Further, even when the turning operation is not performed, it must be stopped at a certain angle.

このため、ケースの旋回軸と同軸上にリングギアを固着して、油圧モーターの出力軸に固着したピニオンを噛み合わせることによって、強大な反力に対抗すべく高い減圧比を得るとともに、通常運転に際してはケースを一定の角度に固定していた。また、強大な反力に対抗すべく油圧シリンダーでケースの旋回を行うアジマススラスターにおいてはケースの旋回角度が全円周角に至らず、一部の角度に限定されていた。   For this reason, a ring gear is fixed on the same axis as the swivel axis of the case, and a pinion fixed to the output shaft of the hydraulic motor is engaged to obtain a high pressure reduction ratio to counter a strong reaction force, and also in normal operation. At that time, the case was fixed at a certain angle. In addition, in the azimuth thruster in which the case is turned by a hydraulic cylinder to counter the strong reaction force, the turning angle of the case does not reach the full circumferential angle but is limited to a part of the angle.

また、従来の手段によるケースの旋回においては、ケースの旋回動作がプロペラの回転速度に干渉してしまうという課題があった。即ち、ケースの反力に抗して旋回する場合には、旋回のために消費された動力が原動機の出力に加算されてプロペラに伝達される。一方、逆の場合には、旋回のために消費された動力が原動機の出力に対して減算されることで、動力損失として失われる。この結果、ケースの旋回動作がプロペラの回転速度に影響を与えてしまっていた。   Further, in the case turning by the conventional means, there is a problem that the turning operation of the case interferes with the rotation speed of the propeller. That is, when turning against the reaction force of the case, the power consumed for turning is added to the output of the prime mover and transmitted to the propeller. On the other hand, in the opposite case, the power consumed for turning is subtracted from the output of the prime mover and lost as power loss. As a result, the turning motion of the case has affected the rotation speed of the propeller.

本発明の目的は、ケースの旋回の動作を容易にし且つケースの旋回動作がプロペラの回転に影響を与えることを防止することである。   An object of the present invention is to facilitate the turning operation of the case and to prevent the turning operation of the case from affecting the rotation of the propeller.

上記目的を達成するための本発明の代表的な構成は、プロペラ駆動源の動力をプロペラに伝達し且つプロペラの方向を旋回可能に形成される旋回式プロペラ装置であって、
一端に前記プロペラが固着され他端に被駆動用歯車が固着されたプロペラ軸と、
前記プロペラ駆動源からの動力を前記プロペラ軸に伝達する駆動伝達軸と、を有し、
前記駆動伝達軸は、一端に前記被駆動用歯車と噛合う外側軸端駆動用歯車を具備する中空の外側軸と、前記外側軸の内部を貫通するように形成され一端に前記被駆動用歯車と噛合う内側軸端駆動用歯車とを具備する内側軸との二重反転軸で構成され、
前記外側軸端駆動用歯車と前記内側軸端駆動用歯車とはそれぞれ、前記被駆動用歯車に対して噛合うことを特徴とする。 A typical configuration of the present invention for achieving the above object is a swivel type propeller device configured to transmit the power of a propeller drive source to a propeller and to turn the direction of the propeller.
A propeller shaft having the propeller fixed to one end and a driven gear fixed to the other end;
A drive transmission shaft that transmits power from the propeller drive source to the propeller shaft;
The drive transmission shaft is formed so as to penetrate a hollow outer shaft having an outer shaft end driving gear meshing with the driven gear at one end, and through the inside of the outer shaft, and the driven gear at one end. An inner shaft having an inner shaft end driving gear meshing with the inner shaft and a counter rotating shaft,
Each of the outer shaft end driving gear and the inner shaft end driving gear meshes with the driven gear.

上述の構成により、ケースの旋回動作に要するトルクがなくなるため、旋回動作によるプロペラ駆動系への動力の出入りもなくなる。このため、ケースの旋回動作がプロペラや原動機の回転に影響を与えることを防止することができる。   With the above-described configuration, the torque required for the turning operation of the case is eliminated, so that power does not enter and exit the propeller drive system due to the turning operation. For this reason, it is possible to prevent the turning operation of the case from affecting the rotation of the propeller and the prime mover.

図面を用いて本発明の実施形態を説明する。   Embodiments of the present invention will be described with reference to the drawings.

図１は本実施形態の旋回式プロペラ装置１の構造を示す図である。   FIG. 1 is a diagram showing a structure of a swivel type propeller device 1 according to the present embodiment.

図１に示すように、旋回式プロペラ装置１は、動力を発生させるプロペラ駆動源２と、プロペラ１１を保持するプロペラ軸１０と、プロペラ駆動源２からの動力をプロペラ軸１０に伝達するための駆動伝達軸２０と、プロペラ軸１０の方向を変える旋回ケース５０と、を有する。旋回式プロペラ装置１は、プロペラ１１を回転させることで船舶や舟艇の推進力を発生させるとともに、当該推進力の発生方向を変えるために旋回ケース５０を旋回させる。この構成について、以下に詳細に説明する。   As shown in FIG. 1, the swivel type propeller device 1 includes a propeller drive source 2 that generates power, a propeller shaft 10 that holds a propeller 11, and power for transmitting the power from the propeller drive source 2 to the propeller shaft 10. A drive transmission shaft 20 and a turning case 50 that changes the direction of the propeller shaft 10 are provided. The swivel type propeller device 1 rotates the propeller 11 to generate a propulsion force of a ship or a boat, and to turn the swivel case 50 in order to change the generation direction of the propulsion force. This configuration will be described in detail below.

プロペラ駆動源２は、例えば、ディーゼルエンジンやガスタービン等の熱機関や、誘導モーターや同期モーター等の電気モーターを用いる。これによってプロペラ１１を駆動するための動力を発生させる。   The propeller drive source 2 uses, for example, a heat engine such as a diesel engine or a gas turbine, or an electric motor such as an induction motor or a synchronous motor. As a result, power for driving the propeller 11 is generated.

プロペラ軸１０は、一端にプロペラ１１が固着され、他端にドリブンギア１２（被駆動用歯車）が固着される。   The propeller shaft 10 has a propeller 11 fixed to one end and a driven gear 12 (driven gear) fixed to the other end.

駆動伝達軸２０は、プロペラ駆動源２からの動力をプロペラ軸１０に伝達する垂直軸である。駆動伝達軸２０は二重反転軸で構成される。具体的には、一端にプロペラ軸１０のドリブンギア１２と噛合う第一ドライブギア３１（外側軸端駆動用歯車）を具備する中空の外側軸３０と、外側軸３０の内部を貫通するように形成され一端にドリブンギア１２と噛合う第二ドライブギア４１（内側軸端駆動用歯車）を具備する内側軸４０とを有する。   The drive transmission shaft 20 is a vertical shaft that transmits power from the propeller drive source 2 to the propeller shaft 10. The drive transmission shaft 20 is composed of a counter rotating shaft. Specifically, a hollow outer shaft 30 having a first drive gear 31 (outer shaft end driving gear) that meshes with the driven gear 12 of the propeller shaft 10 at one end, and the inside of the outer shaft 30 are penetrated. An inner shaft 40 having a second drive gear 41 (inner shaft end driving gear) that is formed and meshes with the driven gear 12 at one end.

旋回ケース５０（操舵部）は、駆動伝達軸２０と同軸において旋回可能な垂直筒型のケースである。旋回ケース５０の中には、図１に示すように駆動伝達軸２０が貫通している。旋回ケース５０の上部には旋回モーター５１（旋回駆動手段）が配設されており、旋回モーター５１の回転駆動により、駆動伝達軸２０を中心として旋回ケース５０が旋回する。旋回ケース５０が旋回すると、プロペラ軸１０の水平面内における方向が変更する。旋回モーター５１は、図１の矢印にあるように、入出力信号が伝達される。具体的には、舵角を検出して、この検出された舵角を不図示の制御手段に知らせる一方、前記舵角に応じた動力を出力するように制御手段から指令がなされる。   The turning case 50 (steering portion) is a vertical cylindrical case that can turn coaxially with the drive transmission shaft 20. As shown in FIG. 1, the drive transmission shaft 20 passes through the turning case 50. A turning motor 51 (turning drive means) is disposed on the upper part of the turning case 50, and the turning case 50 turns around the drive transmission shaft 20 by the rotational drive of the turning motor 51. When the turning case 50 turns, the direction of the propeller shaft 10 in the horizontal plane changes. The swing motor 51 receives input / output signals as indicated by arrows in FIG. Specifically, the control means is instructed to detect the steering angle and inform the control means (not shown) of the detected steering angle, while outputting the power corresponding to the steering angle.

以上のように、駆動伝達軸２０に二重反転軸を採用し、それぞれの軸３０、４０の端部の第一ドライブギア３１と第二ドライブギア４１が、ドリブンギア１２の２つの噛合い箇所で噛合う。これにより、プロペラ軸１０のドリブンギア１２の噛合い力を２つに分割することになる。このため、駆動伝達軸２０のドライブギアとドリブンギア１２との噛合い箇所における一箇所あたりの動力伝達力を軽減することができる。   As described above, a counter rotating shaft is adopted as the drive transmission shaft 20, and the first drive gear 31 and the second drive gear 41 at the ends of the shafts 30 and 40 are in two meshing positions of the driven gear 12. Mesh with each other. Thereby, the meshing force of the driven gear 12 of the propeller shaft 10 is divided into two. For this reason, the power transmission force per location in the meshing location of the drive gear of the drive transmission shaft 20 and the driven gear 12 can be reduced.

第二ドライブギア４１とドリブンギア１２との噛合点は、第一ドライブギア３１とドリブンギア１２との噛合点に対して、プロペラ駆動軸の軸線を挟んでドリブンギア１２の直径方向に反対の位置にある。このように、プロペラ軸１０のドリブンギア１２の直径上に２つの噛合い点があるので、２つの噛合い点に力が均等に配分され、プロペラ軸１０に曲げモーメント荷重が働かない。この結果、プロペラ軸１０の軸受け装置の耐久性の面において有利になる。   The meshing point of the second drive gear 41 and the driven gear 12 is a position opposite to the meshing point of the first drive gear 31 and the driven gear 12 in the diameter direction of the driven gear 12 across the axis of the propeller drive shaft. It is in. Thus, since there are two meshing points on the diameter of the driven gear 12 of the propeller shaft 10, the force is evenly distributed to the two meshing points, and no bending moment load acts on the propeller shaft 10. As a result, this is advantageous in terms of durability of the bearing device for the propeller shaft 10.

また、駆動伝達軸２０を、外側軸３０と内側軸４０の二重反転軸にすることで、駆動伝達軸２０からプロペラ軸１０へのトルクは相殺される。このため、このトルクによる旋回ケース５０への旋回動作における干渉がなくなり、旋回ケース５０を旋回させやすくなる（プロペラ軸１０の方向を変更させやすくなる）。   Moreover, the torque from the drive transmission shaft 20 to the propeller shaft 10 is canceled by making the drive transmission shaft 20 a contra-rotating shaft of the outer shaft 30 and the inner shaft 40. For this reason, interference in the turning operation to the turning case 50 by this torque is eliminated, and the turning case 50 is easily turned (the direction of the propeller shaft 10 is easily changed).

また、このように干渉を除去したことによって、操舵中にプロペラ１１の駆動源の回転数の変化がなくなる。   Further, by removing the interference in this way, the rotation speed of the drive source of the propeller 11 does not change during steering.

また、プロペラ１１への動力を得るドリブンギア１２は水流に直交するため、小径であることが望ましい。ここで、このような小径のドリブンギア１２に動力を伝達するためには、１つのドライブギアで動力を伝達するよりも、本実施形態のように複数のドライブギアに分散して伝達した方が、好ましい。   Moreover, since the driven gear 12 that obtains power to the propeller 11 is orthogonal to the water flow, it is desirable to have a small diameter. Here, in order to transmit power to such a small-diameter driven gear 12, it is better to transmit the power distributed to a plurality of drive gears as in the present embodiment, rather than transmitting the power with one drive gear. ,preferable.

次に、上述の実施形態の旋回式プロペラ装置１を用いた実施例を挙げる。   Next, the Example using the turning type propeller apparatus 1 of the above-mentioned embodiment is given.

〔実施例１〕
まず、旋回式プロペラ装置１の駆動伝達軸２０に動力を伝達する経路上に差動手段６０を設置した例を示す。図２は本実施形態の旋回式プロペラ装置１の実施例１の説明図である。 [Example 1]
First, an example in which the differential means 60 is installed on a path for transmitting power to the drive transmission shaft 20 of the swing type propeller device 1 will be described. FIG. 2 is an explanatory diagram of Example 1 of the swing type propeller device 1 of the present embodiment.

図２に示すように、本実施例においては、プロペラ駆動源２からの駆動を駆動伝達軸２０に伝達するために、差動手段６０を用いた。   As shown in FIG. 2, in this embodiment, the differential means 60 is used to transmit the drive from the propeller drive source 2 to the drive transmission shaft 20.

差動手段６０には、外側軸３０の上端に固着されたベベルギア３２に対して噛合うベベルギア６１と、内側軸４０の上端に固着されたベベルギア４２に対して噛合うベベルギア６２とを具備する二重反転装置を有する。また、差動手段６０には、同軸上で同一方向に回転するベベルギア６１、６２に差動回転を与えるようにギアを配置した差動機構６３を有する。   The differential means 60 includes a bevel gear 61 that meshes with the bevel gear 32 fixed to the upper end of the outer shaft 30, and a bevel gear 62 that meshes with the bevel gear 42 fixed to the upper end of the inner shaft 40. Has a heavy inversion device. Further, the differential means 60 has a differential mechanism 63 in which gears are arranged so as to give differential rotation to bevel gears 61 and 62 that rotate in the same direction on the same axis.

この結果、外側軸３０と内側軸４０とは互いに反転するように回転する。そして、外側軸３０と内側軸４０にそれぞれ固着されたドライブギア３１、４１は、ドリブンギア１２と直径方向の２箇所にて噛合う。このため、プロペラ駆動源２の駆動力が２軸に分散されつつ、ドリブンギア１２に伝達される。   As a result, the outer shaft 30 and the inner shaft 40 rotate so as to reverse each other. The drive gears 31 and 41 fixed to the outer shaft 30 and the inner shaft 40 respectively mesh with the driven gear 12 at two locations in the diameter direction. For this reason, the driving force of the propeller drive source 2 is transmitted to the driven gear 12 while being distributed on two axes.

FIG. 3 is an explanatory diagram of Example 2 of the turning type propeller device 1 of the present embodiment.

図３に示すように、実施例２においては、二重反転軸を回転させるために、２つのモーターを用いる。具体的には、外側軸３０に第一モーター７１のローター７１ａが組み付けられ、内側軸４０に第二モーター７２のローター７２ａが組み付けられる。そして、第一モーター７１のローター７１ａと第二モーター７２のローター７２ａとは反対方向に回転される。これにより、外側軸３０と内側軸４０とは反対方向に回転することになる。尚、上下の外側軸３０は外側軸連結部３３によって連結され、上下の内側軸４０は内側軸連結部４３によって連結される。   As shown in FIG. 3, in Example 2, two motors are used to rotate the counter rotating shaft. Specifically, the rotor 71 a of the first motor 71 is assembled to the outer shaft 30, and the rotor 72 a of the second motor 72 is assembled to the inner shaft 40. The rotor 71a of the first motor 71 and the rotor 72a of the second motor 72 are rotated in opposite directions. As a result, the outer shaft 30 and the inner shaft 40 rotate in opposite directions. The upper and lower outer shafts 30 are connected by an outer shaft connecting portion 33, and the upper and lower inner shafts 40 are connected by an inner shaft connecting portion 43.

図４（ｂ）に示すような２つのインバータ７５、７６を有する構成においては、２つのインバータ７５、７６に指令を出す演算器等の制御手段７７を有する。制御手段７７は、舵角指令値Ｓ１と、モーター回転数（又はモーター角速度）Ｓ２と、舵角検出値Ｓと３を入力として演算し、インバータ７５、７６のそれぞれへ出力周波数を指令する。   In the configuration having the two inverters 75 and 76 as shown in FIG. 4B, the control unit 77 such as an arithmetic unit that issues a command to the two inverters 75 and 76 is provided. The control means 77 calculates the steering angle command value S1, the motor rotation speed (or motor angular velocity) S2, and the steering angle detection values S and 3 as inputs, and commands the output frequencies to the inverters 75 and 76, respectively.

尚、図４（ｂ）に示す構成においては、第一モーター７１と第二モーター７２の回転数の差で、ケース５０を旋回させることができる。このため、操舵用のモーターはなくともよい。   In the configuration shown in FIG. 4B, the case 50 can be turned by the difference in rotational speed between the first motor 71 and the second motor 72. For this reason, there is no need for a steering motor.
