Description
【０００１】[0001]
本考案は、歯車装置に係り、特に主回転軸の回転力を当該主回転軸の所定の回 転数以上で従動歯車に伝達するようにした歯車装置に関する。 The present invention relates to a gear device, and more particularly to a gear device adapted to transmit a rotational force of a main rotating shaft to a driven gear at a predetermined number of rotations of the main rotating shaft or more.
【０００２】[0002]
主駆動源の回転力を他の装置の回転源とするための機構として一般に歯車が用 いられている。 主駆動原の回転数がある定められた値未満ではその回転力が従動歯車に伝達さ れず、上記値以上で伝達されるような回転力伝達機構として、所謂ラチェットホ イール機構（つめ歯車機構）が従来から知られている。 Gears are generally used as a mechanism for using the rotational force of the main drive source as the rotational source of other devices. If the rotational speed of the main drive source is less than a specified value, its rotational force is not transmitted to the driven gear, but is transmitted as a rotational force of more than the above value, a so-called ratchet wheel mechanism (pawl gear mechanism). Is conventionally known.
【０００３】 近年、自然の風を利用して動力を得る手段の１つとして風車が知られている。 特に、風力発電機や揚水機等、産業分野の多方面にわたって風車が利用されるよ うになっている。In recent years, a wind turbine has been known as one of means for obtaining power using natural wind. In particular, wind turbines have come to be used in various fields of industrial fields such as wind power generators and pumps.
【０００４】[0004]
一般に、自然界のある風の強さ（風力）は一定でなく、常に変動しており、あ る強さ以上の風力で発電が可能となる。したがって、風車で回転される主軸（主 駆動軸）の回転数が所定以上となった時に発電機の軸（従動軸）に回転力を伝達 する必要がある。 In general, the strength of the wind in the natural world (wind force) is not constant and constantly fluctuates, and it is possible to generate electricity with wind power above that strength. Therefore, it is necessary to transmit the rotational force to the shaft (driven shaft) of the generator when the rotational speed of the main shaft (main drive shaft) rotated by the wind turbine exceeds a predetermined value.
【０００５】 そのため、ある強さ以上の風力に応じて発電機に回転力を伝達し、それ未満で は切離しされる回転力伝達機構が設けられる。 しかし、上記従来のラチェットホイール方式を用いた機構では、駆動源側の歯 車と従動側の歯車は常時噛み合っており、従動歯車が回転しているような使用状 態では歯車の摩耗や回転騒音が存在する。Therefore, there is provided a rotational force transmission mechanism that transmits a rotational force to the generator according to a wind force having a certain strength or more, and disconnects it if the wind force is less than that. However, in the above-mentioned mechanism using the ratchet wheel method, the gear on the drive source side and the gear on the driven side are always meshed with each other. Exists.
【０００６】 本考案の目的は、主回転軸の回転力と従動軸との間の回転力の伝達と切断を簡 単な構成で自動的に制御する歯車装置を提供することにある。An object of the present invention is to provide a gear device that automatically controls transmission and disconnection of a rotational force between a main rotating shaft and a driven shaft with a simple structure.
【０００７】[0007]
上記目的を達成するために、請求項１に記載の第１の考案は、主回転軸（１ａ ）に取り付けた回転ハブ（１）の円周側壁に均等に形成したブラケット（２）と 、外周に歯を形成した一個の歯車を円周方向に等分した複数の分割歯車片（３） と、この分割歯車片（３）の一端に固定されて他端を前記ブラケット（２）に揺 動自在に支持して前記回転ハブ（１）の所定回転数以上の遠心力で前記複数の分 割歯車片（３）を一体化して前記一個の歯車を形成するためのアーム（３ａ）と 、前記分割歯車片（３）を前記回転ハブ（１）方向に畳み込む方向に偏寄するス プリング（５）と、前記複数の分割歯車片（３）で前記一個の歯車を形成したと きに、当該一個の歯車の歯（３ｂ）に噛合する歯（４ｂ）を備えた従動歯車（４ ）とから構成され、前記回転ハブ（１）の所定の回転数以上での回転力を前記従 動歯車（４）に伝達することを特徴とする。 In order to achieve the above object, the first invention according to claim 1 is to provide a bracket (2) which is evenly formed on a circumferential side wall of a rotary hub (1) attached to a main rotary shaft (1a), and an outer circumference. A plurality of split gear pieces (3) obtained by equally dividing one gear having teeth formed in the circumferential direction, and a plurality of split gear pieces (3) fixed to one end and swinging the other end to the bracket (2). An arm (3a) for freely supporting and integrally forming the plurality of split gear pieces (3) by a centrifugal force of a predetermined number of rotations or more of the rotary hub (1); When the split gear piece (3) is biased toward the direction in which the rotary hub (1) is folded and the plurality of split gear pieces (3) form the one gear, A driven gear (4) having teeth (4b) meshing with the teeth (3b) of one gear. Characterized by transmitting a rotational force at a predetermined rotation number or more of said rotating hub (1) to the slave Dohaguruma (4).
【０００８】 この構成により、主回転軸の所定の回転数以上では分割歯車で形成される一個 の歯車と従動歯車とが噛み合って両者間で回転力の伝達がなされ、上記所定の回 転数未満では従動歯車は自由回転状態となり、歯車間の摩耗が低減され、かつ騒 音の少なくなる。 また、請求項２に記載の第２の考案は、第１の考案における前記ブラケット（ ２）と前記アーム（３ａ）との支持ピン（２ａ）の軸線を、前記回転ハブ（１） の前記所定の回転数未満で前記分割歯車片（３）と前記従動歯車（４）との係合 が解除された状態で前記回転ハブ（１）に近づく方向に重なって折り畳まれる分 だけ前記回転ハブ（１）の中心線と平行な線に対してズレを持たせたことを特徴 とする。With this configuration, at a predetermined rotational speed of the main rotating shaft or more, one gear formed by the split gear and the driven gear mesh with each other to transmit the rotational force between the two, and the rotational speed is less than the predetermined rotational speed. Then, the driven gear becomes free rotation, wear between gears is reduced, and noise is reduced. The second invention according to claim 2 is such that the axis of the support pin (2a) between the bracket (2) and the arm (3a) in the first invention is set to the predetermined value of the rotary hub (1). When the rotational speed of the rotary hub (1) is smaller than the rotational speed of the above, the split gear piece (3) and the driven gear (4) are disengaged from each other and overlapped and folded in the direction approaching the rotary hub (1). The feature is that the line parallel to the center line of () has a deviation.
【０００９】 これにより、上記主回転軸の所定の回転数未満での上記分割歯車片（３）はハ ブ（１）側に畳み込まれる。As a result, the split gear piece (3) at a rotational speed lower than the predetermined value of the main rotary shaft is folded to the hub (1) side.
【００１０】[0010]
以下、本考案の実施の形態につき、実施例の図面を参照して詳細に説明する。 図１は本考案による歯車装置の１実施例を説明する平面図であって、主回転軸 が低速回転ないしは停止の状態を示し、１ａは主回転軸、１は主回転軸に取り付 けたハブ、２はブラケット、２ａは支持ピン、３は分割歯車、３ａはアーム、３ ｂは分割歯車の歯、３ｃは回動軸、３ｄはピン孔、４は従動歯車、４ａは従動回 転軸、４ｂは従動歯車の歯、５は戻りバネである。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings of the embodiments. FIG. 1 is a plan view for explaining an embodiment of a gear device according to the present invention, in which a main rotating shaft is in a low speed rotating or stopped state, 1a is a main rotating shaft, and 1 is a hub attached to the main rotating shaft. 2 is a bracket, 2a is a support pin, 3 is a split gear, 3a is an arm, 3b is a split gear tooth, 3c is a rotation shaft, 3d is a pin hole, 4 is a driven gear, 4a is a driven rotation shaft, Reference numeral 4b is a tooth of the driven gear, and 5 is a return spring.
【００１１】 図２は図１のＡ−Ａ線で切断した断面図、図３は図１の矢印Ｂ方向から見た要 部側面図である。 図１、図２および図３に示したように、分割歯車３は一個の歯車を円周方向に ４分割してなり、その各一方の端部に一端を固定したアーム３ａの他端に形成し た回動軸３ｃをハブ１に形成したブラケット２に支持ピン２ａをピン孔３ｄに挿 通することで揺動自在に取り付けてある。FIG. 2 is a cross-sectional view taken along the line AA of FIG. 1, and FIG. 3 is a side view of the main part as seen from the direction of arrow B in FIG. As shown in FIGS. 1, 2 and 3, one split gear 3 is formed by dividing one gear into four in the circumferential direction, and is formed at the other end of the arm 3a having one end fixed to one end thereof. The rotating shaft 3c is attached to the bracket 2 formed on the hub 1 so as to be swingable by inserting the support pin 2a into the pin hole 3d.
【００１２】 上記支持ピン２ａの軸線は主回転軸１の中心軸と平行な線Ｘ−Ｘと平行な線に 対してθだけずらして設置されている。 したがって、４個の分割歯車３が図示の畳み込まれた状態では、各分割歯車３ は隣接する分割歯車のアームの上方に位置するごとく若干傾斜して相互が当接す ることが回避されている。The axis line of the support pin 2 a is set to be offset by θ with respect to the line parallel to the line X-X parallel to the central axis of the main rotation shaft 1. Therefore, in the state in which the four split gears 3 are folded up as shown in the drawing, each split gear 3 is prevented from abutting against each other while being slightly inclined as it is located above the arm of the adjacent split gear. There is.
【００１３】 図４は分割歯車の一つの構成を説明する斜視図であって、分割歯車３の一方の 端部の下面にアーム３が一体的に固定され、このアーム３の他端に形成された回 動軸３ｃにはピン孔３ｄが形成されている。 また、各分割歯車の両端は、隣接の分割歯車と一体化して一個の歯車を形成す るときに当該一個の歯車の径を維持するための斜面３ｅ，３ｆが形成されている 。そして、分割歯車３の外周面には歯３ｂが形成され、従動歯車と係合するよう になっている。FIG. 4 is a perspective view for explaining one structure of the split gear. The arm 3 is integrally fixed to the lower surface of one end of the split gear 3 and is formed at the other end of the arm 3. A pin hole 3d is formed in the rotating shaft 3c. Further, both ends of each divided gear are formed with slopes 3e and 3f for maintaining the diameter of the one gear when integrally forming with one adjacent divided gear to form one gear. Further, teeth 3b are formed on the outer peripheral surface of the split gear 3 so as to engage with the driven gear.
【００１４】 この分割歯車３は、戻しバネ５により常時は図１に示した状態に偏寄されてい る。 図５は本考案による歯車装置の１実施例を説明する主回転軸が所定の回転数以 上で従動歯車と係合した状態を示す平面図、図６は図５のＡ−Ａ線で切断した断 面図、図７は図５の矢印Ｂ方向から見た要部側面図である。The split gear 3 is normally biased to the state shown in FIG. 1 by the return spring 5. FIG. 5 is a plan view showing a state in which a main rotating shaft is engaged with a driven gear at a predetermined rotation speed or more, for explaining one embodiment of the gear device according to the present invention, and FIG. 6 is a sectional view taken along line AA of FIG. FIG. 7 is a side view of the main part as seen from the direction of arrow B in FIG.
【００１５】 同各図に示したように、主回転軸１ａが所定の回転数以上となると、各分割歯 車３は遠心力によって戻りバネ５に抗して広がり、各斜面３ｅと３ｆの当接で寄 生されて真円となり、従動歯車４と係合する。 このとき、各分割歯車３のアーム３ａは回転面に収まり、この状態で主回転軸 １ａの回転力は従動歯車４に伝達されることになる。As shown in the respective figures, when the main rotating shaft 1a reaches a predetermined number of rotations or more, each split tooth gear 3 spreads against the return spring 5 due to centrifugal force, and the slopes 3e and 3f come into contact with each other. It is generated by contact and becomes a perfect circle, and engages with the driven gear 4. At this time, the arm 3a of each of the split gears 3 is contained in the rotation surface, and in this state, the rotational force of the main rotation shaft 1a is transmitted to the driven gear 4.
【００１６】[0016]
以上説明したように、本考案によれば、簡単な機構で主回転軸の回転数が所定 値以上においてその回転力が従動歯車に伝達されると共に、上記所定の回転数未 満では従動歯車との係合が解除されて回転力は伝達されなくなって、歯車の摩耗 や騒音が低減される。 As described above, according to the present invention, the rotation force of the main rotary shaft is transmitted to the driven gear when the rotation speed of the main rotation shaft is equal to or higher than a predetermined value, and when the rotation speed of the main rotation shaft is lower than the predetermined value, Is disengaged and torque is no longer transmitted, and gear wear and noise are reduced.
