Description

【０００１】
【発明の属する技術分野】
本発明は、風力発電等に用いられる増速機の支持装置に関し、特に増速機を架台に防振的に支持するようにした防振支持装置に関する。
【０００２】
【従来の技術】
従来の防振支持構造について説明すると、図４〜６において符号１は増速機を示しており、増速機１の機械音（振動）を架台５に個体伝播させないために増速機１と架台５との間の全面にゴム板などの防振プレート９を敷設し、防振プレート９の上に増速機１を据付けて、機械音（振動）の個体伝播を減衰させる構造が採用されている。
【０００３】
図４中の符号６は発電機を示しており、発電機６の被動軸６ａは増速機１の出力軸１ａに接続されている。また、増速機１の架台５への取付けは、図６に示すように、増速機１のフランジ部１ｃを貫通する固定ボルト７を架台５のフランジ部５ａにワッシャ７ａ，ブッシュ８を介して締付けることにより行なわれる。
【０００４】
また、このほか図７〜９に示すように、増速機１の４カ所に支持脚２ａ〜２ｄと１カ所の位置決め用脚10とを設け、各支持脚２ａ〜２ｄをそれぞれ防振ブッシュ３を介して、また位置決め用脚10を位置決め用ブッシュ４を介して、それぞれ架台５上の取付け金具13, 14に取付けることにより、機械音の架台５への個体伝播を減衰させる構造のものも提案されている。
【０００５】
【発明が解決しようとする課題】
ところで、図４〜６に示した従来の防振支持構造のものでは、増速機１を架台５に締付ける固定ボルト７からも増速機１の機械音が架台５へ個体伝播されるため、個々の固定ボルト７についてもブッシュ８を介して増速機１を架台５へ固定する構造となっている。
【０００６】
さらに、弾性体製の防振プレート９は、単位当たり面積の面圧強度を高く取ることができないため、防振プレート（弾性体）を増速機の据付け面全面に敷くなど大きくとる必要があり、さらに弾性体（防振プレート）を増速機の下部に設けるために運転中の熱伸びおよび伝達トルクで増速機１と発電機６との間の軸アラインメントに大きな狂いを生じるという課題がある。
【０００７】
また図７〜９に示した従来の防振支持構造のものでは、増速機１の重量を支える防振ブッシュ３と軸方向の動きを止める位置決め用ブッシュ４とを別々に設ける必要があり、さらに防振ブッシュ３と位置決め用ブッシュ10とでは取付け位置および取付け高さが異なるため、運転中の熱伸びおよび片側のみの支持である等の理由によって、支持力のアンバランスが発生し、伝達トルクにより増速機１と発電機６との軸アラインメントに大きな狂いが生じるという課題がある。
本発明は、従来の防振支持構造におけるこれらの課題を解決しようとするものである。
【０００８】
【課題を解決するための手段】
本発明は、増速機の支持装置において、上記増速機の四隅部に、同一レベルに４本の支持脚を水平方向に突設し、同各支持脚を実質上同一長さに設定するとともに同各支持脚の各先端部を上記増速機の支持台としての架台にそれぞれ防振ブッシュを介して取付け、上記４本の支持脚のうちの上記増速機の高速側の回転軸に関し対称に配設された２本の支持脚を、それぞれ取付け方向を同増速機の高速側の回転軸に対し傾けて上記増速機に取付けることにより課題解決の手段としている。
【０００９】
本発明では、増速機の重量の支持および架台との結合を防振ブッシュを介して行なうようにしたため、機械音（振動）は減衰して架台へ伝達され、架台における機械音は低減される。
【００１０】
また、４本の実質上同一長さの支持脚を増速機の同一レベル位置に水平方向に突設したことにより、運転中の熱伸びを均等にすることができ、また４本の支持脚のうちの増速機の高速側の回転軸に関して対称な２本の支持脚の取付け方向を増速機の回転軸中心に対して傾けたことにより、増速機の軸方向の動きおよび回転トルクによる振れ回りを防止できる。
【００１１】
【発明の実施の形態】
以下、図面により本発明の一実施形態としての風力発電用増速機の防振支持装置について説明すると、図１はその装置全体を示す側面図、図２はその増速機の防振支持装置を示す斜視図、図３は図２のＡ矢部を拡大して示す正面図である。
なお図１〜３中図４〜９と同じ符号はほぼ同一の部材を示している。
【００１２】
この実施形態では、風力発電装置に適用した場合を例としており、この風力発電装置は、発電機６と風力装置の回転力を増速して発電機６を駆動する増速機１とをそなえて構成されている。
【００１３】
図１中の符号20は風車（図示せず）の回転力の取出し部を、符号21はカップリングを示しており、このカップリング21の出力軸21ａに増速機１の入力軸１ｂが接続されている。そして、増速機１は架台５に防振的に取付けられている。
【００１４】
すなわち、図２に示すように、増速機１の四隅部の同一レベル上に、４本の支持脚２ａ，２ｂ，２ｃ，２ｄが増速機１の軸方向（図１の左右方向）と直交する方向にかつ水平に延在するように取付けられている。各支持脚２ａ〜２ｄはすべて実質上同一長さに形成されるとともに、各支持脚２ａ〜２ｄの各先端部に形成された円孔に、リング状の防振ブッシュ３がそれぞれ装着されている。
ここで、実質上同一長さとは、各支持脚２ａ〜２ｄの増速機１への取付け部から後述の軸15の中心までの直線距離が、同じ長さであるということである。
防振ブッシュ３は、図３に示すようにリング状のゴム等の弾性体３ａと同弾性体３ａの内外周を囲む金属製の環体３ｂ，３ｃとで形成されている。
【００１５】
一方、取付け金具13は架台５に取付けられる基板部13ｃと基板部13ｃに垂直状に立設された左右一対の腕部13ａ, 13ｂとで構成されている。そして、腕部13ａ，13ｂの間に軸15が架設され、防振ブッシュ３の中心穴に軸15を挿通することで、各支持脚２ａ〜２ｄすなわち増速機１を架台５に防振的に支持する防振支持装置を構成している。
【００１６】
上述の構成により、増速機１と架台５とは防振ブッシュ３を介して固定されているため、増速機１で発生した大部分の機械音（振動エネルギー）は防振ブッシュ３で大幅に減衰されて架台５へ伝達されることとなり、架台５への個体伝播音を大幅に低減できる。
【００１７】
防振ブッシュ３のゴム３ａの厚さを変えて防振ブッシュ３自身の剛性を変えることで、防振ブッシュ３で吸収（減衰）できる周波数帯を選択でき、特に人に不快感を与える歯車の噛み合い音などの高周波帯域の振動（音）を低減することができる。
【００１８】
また、防振ブッシュ３はゴム３ａの内外周を金属環３ｂ，３ｃで囲う構成となっているため、ゴム３ａの変形量を金属環３ｂ，３ｃで拘束でき、防振ブッシュ３の剛性を増加させることができる。
【００１９】
また、４本の支持脚２ａ〜２ｄが同一水平面上に突設されているため、運転中の熱伸びによるミスアラインメント（増速機１と発電機６との軸アラインメントの狂い）を吸収でき、さらに４本の支持脚２ａ〜２ｄは実質上同一長さに形成されているため支持半径が同一となり、伝達トルクのアンバランスによるミスアラインメントを吸収できる。
【００２０】
さらに、同一レベル位置の４カ所に設けた支持脚２ａ〜２ｄのうち、伝達トルクの小さい高速側の回転軸１ａに関し対称に配設された２本の支持脚２ｃ，２ｄに曲げ角部２ｆを形成して、増速機１に対する取付け方向を増速機１の中心側に向ける構成、つまり増速機１の高速側の回転軸１ａに対して取付け部２ｅを角度ａだけ傾けて増速機１に取付ける構成とすることにより、風車のコーンアングル（ナセルの傾き）による増速機１の軸方向の移動止めおよび伝達トルク（回転力）による振れ回りを止めることができる。
【００２１】
【発明の効果】
以上詳述したように、本発明の増速機の防振支持装置によれば次のような効果ないし利点が得られる。
(1) 実質上同一長さの４本の支持脚を増速機の四隅部に、同一レベルに水平方向に突設したことにより、運転中の熱伸びを均等にすることができ、増速機と発電機との軸アラインメントの狂いを一定に制限することができる。
(2) 増速機の重量の支持および架台との結合を防振ブッシュを介して行なうようにしたため、機械音（振動）は減衰して架台へ伝達され、架台における機械音を低減することができる。
(3) ４本の支持脚のうちの増速機の高速側の回転軸に関して対称な２本の支持脚の取付け方向を増速機の高速側の回転軸に対し傾けたことにより、運転中の熱延びを吸収して増速機の軸方向の動きおよび回転トルクによる振れ回りを防止できる。

BACKGROUND OF THE INVENTION
The present invention relates to a support device for a gearbox used for wind power generation or the like, and more particularly to a vibration-proof support device that supports a gearbox on a gantry in a vibration-proof manner.
[0002]
[Prior art]
The conventional anti-vibration support structure will be described. In FIGS. 4 to 6, reference numeral 1 denotes a speed increaser. In order to prevent the mechanical sound (vibration) of the speed increaser 1 from propagating to the gantry 5, A structure is adopted in which a vibration isolating plate 9 such as a rubber plate is laid on the entire surface between the base 5 and the gearbox 1 is installed on the vibration isolating plate 9 to attenuate individual propagation of mechanical sound (vibration). ing.
[0003]
Reference numeral 6 in FIG. 4 denotes a generator, and the driven shaft 6 a of the generator 6 is connected to the output shaft 1 a of the speed increaser 1. Further, as shown in FIG. 6, the speed increaser 1 is attached to the gantry 5 by using a fixing bolt 7 penetrating the flange portion 1 c of the speed increaser 1 through a washer 7 a and a bush 8 on the flange portion 5 a of the gantry 5. It is done by tightening.
[0004]
In addition, as shown in FIGS. 7 to 9, support legs 2 a to 2 d and one positioning leg 10 are provided at four positions of the speed increaser 1, and each of the support legs 2 a to 2 d is provided with a vibration isolation bush 3. Also proposed is a structure that attenuates the individual propagation of mechanical sound to the gantry 5 by attaching the positioning leg 10 to the mounting brackets 13 and 14 on the gantry 5 via the positioning bushing 4 Has been.
[0005]
[Problems to be solved by the invention]
By the way, in the thing of the conventional vibration-proof support structure shown in FIGS. 4-6, since the mechanical sound of the gearbox 1 is propagated to the stand 5 also from the fixing bolt 7 which fastens the gearbox 1 to the stand 5, Each of the fixing bolts 7 is also structured to fix the speed increaser 1 to the gantry 5 via the bush 8.
[0006]
Further, since the vibration isolating plate 9 made of an elastic material cannot have a high surface pressure strength per unit area, it is necessary to make the vibration isolating plate (elastic body) large on the entire installation surface of the gearbox. Furthermore, since an elastic body (vibration-proof plate) is provided at the lower part of the gearbox, there is a problem that a large deviation occurs in the shaft alignment between the gearbox 1 and the generator 6 due to thermal expansion and transmission torque during operation. is there.
[0007]
Further, in the conventional anti-vibration support structure shown in FIGS. 7 to 9, it is necessary to separately provide the anti-vibration bush 3 that supports the weight of the speed increaser 1 and the positioning bush 4 that stops the movement in the axial direction. Furthermore, since the mounting position and the mounting height of the vibration isolating bush 3 and the positioning bush 10 are different, the unbalance of the supporting force occurs due to the thermal expansion during operation and the support on only one side, and the transmission torque. As a result, there is a problem that the shaft alignment between the speed increaser 1 and the generator 6 causes a big error.
The present invention is intended to solve these problems in the conventional vibration-proof support structure.
[0008]
[Means for Solving the Problems]
According to the present invention, in the support device for the speed increaser, four support legs are projected horizontally at the same level at the four corners of the speed increaser, and the support legs are set to have substantially the same length. with attached via the cradle to the vibration isolating bushing each respective tip of the respective support leg as a support base of the speed increaser, the high-speed side of the gearbox of the support legs of the upper Symbol four rotating shaft and a means of solving the problem by mounting Rukoto the two supporting legs which are disposed symmetrically, each mounting direction Shi pair high-speed side of the rotation axis of the speed increaser tilting the with the gearbox relates.
[0009]
In the present invention, the weight of the speed increaser is supported and coupled to the gantry via the vibration isolating bush, so that the mechanical sound (vibration) is attenuated and transmitted to the gantry, and the mechanical noise in the gantry is reduced. .
[0010]
Further , by providing four support legs of substantially the same length in the horizontal direction at the same level position of the gearbox, the thermal expansion during operation can be made uniform, and the four support legs are also provided. Of the speed increaser by tilting the mounting direction of the two support legs symmetric with respect to the rotation axis on the high speed side of the speed increaser with respect to the rotation axis center of the speed increaser. Can be prevented from swinging around.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the anti-vibration supporting device of the wind power generation gearbox as an embodiment of the present invention will be described with reference to the drawings, FIG. 1 is a side view showing the entire apparatus, FIG. 2 is vibration-damping support device of the speed increaser FIG. 3 is an enlarged front view showing an arrow A in FIG.
1 to 3 indicate substantially the same members.
[0012]
In this embodiment, an application of the wind turbine generator is an example, the wind turbine generator, and a speed increaser 1 to accelerated rotational force of the generator 6 and wind device drives a generator 6 It is composed.
[0013]
Reference numeral 20 in FIG. 1 denotes a rotational force take-out portion of a wind turbine (not shown), and reference numeral 21 denotes a coupling. An input shaft 1 b of the speed increaser 1 is connected to an output shaft 21 a of the coupling 21. Has been. The speed increaser 1 is attached to the gantry 5 in a vibration-proof manner.
[0014]
That is, as shown in FIG. 2, four support legs 2a, 2b, 2c, and 2d are on the same level at the four corners of the speed increaser 1, and the axial direction of the speed increaser 1 (the left-right direction in FIG. 1). It is attached so as to extend in an orthogonal direction and horizontally. Each of the support legs 2a to 2d is formed to have substantially the same length, and a ring-shaped anti-vibration bush 3 is mounted in a circular hole formed at each tip of each of the support legs 2a to 2d. .
Here, “substantially the same length” means that the linear distances from the attachment portions of the support legs 2 a to 2 d to the speed increaser 1 to the center of the shaft 15 described later are the same length.
As shown in FIG. 3, the vibration isolating bush 3 is formed of an elastic body 3 a such as a ring-shaped rubber and metal rings 3 b and 3 c surrounding the inner and outer circumferences of the elastic body 3 a.
[0015]
On the other hand, the mounting bracket 13 is composed of a board part 13c attached to the gantry 5 and a pair of left and right arm parts 13a, 13b erected vertically on the board part 13c. Then, a shaft 15 is installed between the arm portions 13a and 13b, and the shaft 15 is inserted into the center hole of the vibration isolating bush 3 so that the support legs 2a to 2d, that is, the speed increaser 1 are vibration-isolating. An anti-vibration support device is supported.
[0016]
With the above-described configuration, the gearbox 1 and the gantry 5 are fixed via the vibration isolating bush 3, so that most of the mechanical noise (vibration energy) generated by the gearbox 1 is greatly reduced by the vibration isolating bush 3. It is attenuated to be transmitted to the gantry 5, and the sound of individual propagation to the gantry 5 can be greatly reduced.
[0017]
By changing the thickness of the rubber bush 3a of the anti-vibration bush 3 and changing the rigidity of the anti-vibration bush 3 itself, the frequency band that can be absorbed (damped) by the anti-vibration bush 3 can be selected. Vibration (sound) in a high frequency band such as a meshing sound can be reduced.
[0018]
Further, since the vibration isolating bush 3 has a configuration in which the inner and outer periphery of the rubber 3a is surrounded by the metal rings 3b and 3c, the deformation amount of the rubber 3a can be restricted by the metal rings 3b and 3c, and the rigidity of the vibration isolating bush 3 is increased. Can be made.
[0019]
Further, since the four support legs 2a to 2d are projected on the same horizontal plane, it is possible to absorb misalignment due to thermal expansion during operation (a shaft alignment error between the gearbox 1 and the generator 6). Further, since the four support legs 2a to 2d are formed to have substantially the same length, the support radii are the same, and misalignment due to imbalance of the transmission torque can be absorbed.
[0020]
Further, of the support legs 2a to 2d provided at four positions at the same level position, bending angle portions 2f are provided on the two support legs 2c and 2d arranged symmetrically with respect to the rotating shaft 1a on the high speed side with a small transmission torque. formed to the configuration to direct the mounting direction for the up gear 1 toward the center of the speed increaser 1, i.e. up gear by tilting the mounting portion 2e angle a with respect to the high-speed side of the rotation shaft 1a of the speed increaser 1 By adopting the configuration of being attached to 1, it is possible to stop the axial movement of the gearbox 1 due to the cone angle of the windmill (the inclination of the nacelle) and the swinging due to the transmission torque (rotational force).
[0021]
