Description
【０００１】[0001]
本考案は風力発電用風車ヘッドの改良に関するものである。 The present invention relates to an improved wind turbine head for wind power generation.
【０００２】[0002]
風力発電機は古くから知られている。これは風力でプロペラを回し、この回転 動力を地上の発電機に伝へて発電するものである。しかし、プロペラで得られた 回転動力を発電機に効率良く伝える装置がなかった為、発電効率は勿論その寿命 の点でも好しくなかった。 Wind generators have long been known. This is to rotate the propeller with wind power and transmit this rotational power to a generator on the ground to generate electricity. However, since there was no device that efficiently transmitted the rotational power obtained by the propeller to the generator, the power generation efficiency was of course unfavorable in terms of its life.

図１は風車ヘッドの縦断面図、図２は片半部断面の平面図である。図において 、１は風車軸４の風車取付部で、図示しない風車がキ−２によって風車軸４に取 付けられ側方からナット３で締付けられる。風車軸４は上部ケ−ス5a内に軸受６ で支持されている。風車軸４の他端には傘歯車７がキ−7aを介し嵌挿され、ねじ ８で固着されている。 FIG. 1 is a vertical cross-sectional view of a wind turbine head, and FIG. 2 is a plan view of a half-half section. In the figure, reference numeral 1 denotes a wind turbine mounting portion of a wind turbine shaft 4, a wind turbine (not shown) is attached to the wind turbine shaft 4 by a key-2 and tightened with a nut 3 from the side. The wind turbine shaft 4 is supported by a bearing 6 in the upper case 5a. A bevel gear 7 is inserted into the other end of the wind turbine shaft 4 through a key 7a and fixed by a screw 8.
【０００６】 ９は風車軸４と直交する歯車軸で上部ケ−ス5aと下部ケ−ス5bの締付ボルトを 兼ねている。この歯車軸９には歯車１０が軸受を介し軸方向及び円周方向に可動 即ち歯車軸９に対しフリ−状態で嵌挿されている。歯車軸９は下端でナット１１ で締め付け上・下部ケ−スは一体化されている。１２は止めねじ、１３はキャッ プである。歯車１０は風車軸４側の傘歯車７と噛合う上部の傘歯車10a と下部の 平歯車10bが一体に構成されている。Reference numeral 9 denotes a gear shaft orthogonal to the wind turbine shaft 4 and also serves as a fastening bolt for the upper case 5a and the lower case 5b. A gear 10 is axially and circumferentially movable via a bearing on the gear shaft 9, that is, is fitted in the gear shaft 9 in a free state. The lower end of the gear shaft 9 is fastened with a nut 11 so that the upper and lower cases are integrated. 12 is a set screw, and 13 is a cap. The gear 10 is integrally configured with an upper bevel gear 10a and a lower spur gear 10b which mesh with the bevel gear 7 on the wind turbine shaft 4 side.
【０００７】 １４は平歯車10b と噛合う平歯車で、歯車軸９と平行に下部ケ−ス5b内にナッ ト１７で取付けられた伝動軸１５にキ−14a を介し回転可能に取り付けられてい る。１６は平歯車１４の上部を被う蓋である。伝動軸１５の下端には発電機が設 置されている。１８は上部ケ−ス5aに取付けられた翼（方向舵）である。Reference numeral 14 is a spur gear which meshes with a spur gear 10b, which is rotatably attached to a transmission shaft 15 mounted in parallel with the gear shaft 9 in a lower case 5b by a nut 17 via a key 14a. It Reference numeral 16 is a lid that covers the upper portion of the spur gear 14. A generator is installed at the lower end of the transmission shaft 15. Reference numeral 18 is a wing (rudder) attached to the upper case 5a.
【０００８】[0008]
以上の構成であって、図示しない風車に風が当ると、風車がまわる。すると風 車軸４と共に傘歯車７が回る。傘歯車７が回ると、歯車軸９に嵌挿された歯車１ ０の傘歯車10aを介し下部の平歯車10bも同一回転数で回る。するとこれと噛み合 う平歯車１４を介し伝動軸１５が回り発電機を駆動する。 With the above configuration, when wind hits a wind turbine (not shown), the wind turbine rotates. Then, the bevel gear 7 rotates together with the wind turbine shaft 4. When the bevel gear 7 rotates, the lower spur gear 10b also rotates at the same rotation speed via the bevel gear 10a of the gear 10 fitted into the gear shaft 9. Then, the transmission shaft 15 is rotated via the spur gear 14 meshing with this to drive the generator.

一端に風車を固定し他端に傘歯車７が取付けられ上部ケ−ス5aで被われた風車 軸４と上部ケ−ス5aと下部ケ−ス5bを締付けると共に前記傘歯車７と噛合う上部 の傘歯車10aと下部の平歯車10bとを備え歯車軸９に対しフリ−状態で歯車１０を 嵌挿された歯車軸９と、前記歯車１０の下部平歯車10b と噛合う平歯車１４を上 部に固着した伝動軸１５とからなり、伝動軸１５の下端に発電機を設置し駆動す るようにした。 このように構成したので、風車の回転によって得られた動力は風車軸端の傘歯 車７から軸方向と周方向に可動な歯車１０を経て伝動軸１５にスム−ズに伝える ことができる。この場合風力の強弱、風向きの急変等で風車軸４から伝動軸１５ への伝動に際し無理な力が作用するが、歯車軸９に対しフリ−な歯車１０の存在 によって衝撃力を緩和でき、メインテナンスが極めて容易である。 上部ケ−ス5aと下部ケ−ス5bを分割できるので、これ又メインテナンスを容易 にすることができる。 The wind turbine is fixed to one end and the bevel gear 7 is attached to the other end, and the wind turbine shaft 4, the upper case 5a, and the lower case 5b are covered with the upper case 5a. A bevel gear 10a and a lower spur gear 10b, and a gear shaft 9 in which the gear 10 is inserted in a free state with respect to the gear shaft 9, and a spur gear 14 that meshes with the lower spur gear 10b of the gear 10 It consists of a transmission shaft 15 fixed to the part, and a generator is installed at the lower end of the transmission shaft 15 so that it can be driven. With this configuration, the power obtained by the rotation of the wind turbine can be smoothly transmitted from the bevel gear 7 at the wind turbine shaft end to the transmission shaft 15 via the gear 10 movable in the axial direction and the circumferential direction. In this case, an unreasonable force acts on the transmission from the wind turbine shaft 4 to the transmission shaft 15 due to the strength of the wind force, a sudden change in the wind direction, etc. However, due to the existence of the free gear 10 against the gear shaft 9, the impact force can be alleviated, and maintenance is performed. Is extremely easy. Since the upper case 5a and the lower case 5b can be divided, this also facilitates maintenance.
