【考案の属する技術分野】[Technical field to which the device belongs]

この考案は、一方向の回転を許容し、他方向の回転を阻止する偏平型一方向クラッチに関する。 The present invention relates to a flat type one-way clutch that allows rotation in one direction and prevents rotation in the other direction.

【０００２】[0002]

【従来の技術】[Prior art]

従来、回転部材の一方向の回転を許容し、他方向の回転を阻止するために、ころがり部材のクサビ作用による逆転時の遊度が少ないこと及び簡単に回転部材と支持体との間に装着出来る一方向クラッチとして、外輪内に複数個の棒状の円柱ころがり部材を保持体に保持すると共に外輪内に嵌入した一方向クラッチが用いられている。そして、このような従来の一方向クラッチの保持体に保持されるころがり部材は、軸方向の高さが高く、外径が細い形状となっている。 Conventionally, in order to allow rotation of the rotating member in one direction and prevent rotation in the other direction, there is little play during reverse rotation due to the wedge action of the rolling member, and between the rotating member and the support easily. As a one-way clutch that can be mounted on a vehicle, a one-way clutch is used in which a plurality of rod-shaped cylindrical rolling members are held by a holder in the outer ring and are fitted into the outer ring. The rolling member held by the holding body of such a conventional one-way clutch has a high axial height and a thin outer diameter.

【０００３】従来の一方向クラッチは、内輪体の外径が細く、製品の軸方向の長さを問わず回転数が比較的遅い製品に組み込む時は支障はないが、内輪体の外径が比較的に大きく、製品の軸方向の長さが短く、回転数が比較的速い製品に組み込む時は次のような支障が発生する。In the conventional one-way clutch, the outer diameter of the inner ring body is small, and there is no hindrance when it is incorporated into a product whose rotation speed is relatively slow regardless of the axial length of the product. When installed in a product that is relatively large, has a short axial length, and has a relatively high rotation speed, the following problems occur.

【０００４】１）内輪体の外径が比較的に大きい時に、ころがり部材の外径を従来と同径の棒状円柱のまま軸方向の高さを低くした一方向クラッチを製作して用いると、ころがり部材の面圧が高くなって回転衝撃でころがり部材が外輪体と内輪体に喰い込みロックしてしまったり、又、局部的なキズ、変形、磨耗等を促進してしまう欠点がある。２）一方向クラッチは、そのころがり部材が内輪体に押し付けられ、摺り合い状態にあるが、ころがり部材の数が多いと回転力が重くなり、ころがり部材の数を減らすと、伝達許容トルクが比例して下がる欠点がある。３）棒状の円柱ころがり部材の自重を軽くするためにそれを短くすると、前記１）のようにころがり部材が外輪体と内輪体に喰い込みロックしてしまう欠点がある。1) When the outer diameter of the inner ring body is relatively large, a rolling clutch having the same outer diameter as the conventional rod-shaped cylinder is used, but a one-way clutch having a low axial height is manufactured and used. The surface pressure of the rolling member becomes high, and the rolling member gets caught by the outer ring body and the inner ring body due to the rotational impact and locks, and it also has the drawback of promoting local scratches, deformation, wear, etc. . 2) In the one-way clutch, the rolling members are pressed against the inner ring body and are in sliding contact with each other. However, if the number of rolling members is large, the rotational force will be heavy, and if the number of rolling members is reduced, the allowable transmission torque will be proportional. There is a downside. 3) If the rod-shaped cylindrical rolling member is shortened in order to reduce its own weight, there is a drawback that the rolling member bites into the outer ring body and the inner ring body and locks as described in 1) above.

【０００５】[0005]

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

解決しようとする問題点は、従来構造の一方向クラッチを内輪体の外径が比較的に大きく、製品の軸方向の長さが短く回転数が比較的速い製品に組み込むと、一方向クラッチとして十分なクラッチ機能が得られないことである。本考案の目的は前記欠点に鑑み、内輪体の外径が比較的に大きく、製品の軸方向の長さが短く、回転数が比較的速い製品に組み込んでも、良好な一方向クラッチ機能が得られる偏平型一方向クラッチを提供することである。 The problem to be solved is that if a conventional one-way clutch is incorporated into a product with a comparatively large outer diameter of the inner ring body and a short axial length of the product and a relatively high rotation speed, it becomes a one-way clutch. That is, a sufficient clutch function cannot be obtained. In view of the above-mentioned drawbacks, the object of the present invention is that the outer diameter of the inner ring body is relatively large, the axial length of the product is short, and that the product has a good one-way clutch function even when incorporated in a product with a relatively high rotational speed. To provide a flat type one-way clutch.

【問題を解決するための手段】[Means for solving the problem]

本考案は、外枠体と内輪体との間に複数個のころがり部材を保持する保持体を設けて成る一方向クラッチにおいて、前記ころがり部材の形状を高さより外径寸法を大きく形成した円盤状としている。この円盤状のころがり部材は、外枠体が一方向に回転した際、内周面が多角形状となった外枠体の自由回転域、もしくは複数箇所に突出部が形成されている外枠体の突出部によって規定される自由回転域に位置して、外枠体の回転を可能とする。また、円盤状のころがり部材は、外枠体が反対方向に回転した際、自由回転域からクサビ作用による阻止域に移動して、外枠体の反対方向の回転を阻止する。 The present invention relates to a one-way clutch comprising a holding member for holding a plurality of rolling members between an outer frame member and an inner ring member, wherein the rolling member is formed to have an outer diameter dimension larger than a height. I am in a state. This disk-shaped rolling member is an outer frame body in which the outer peripheral body has a polygonal shape on the inner peripheral surface when the outer frame body rotates in one direction, or the outer frame body has protrusions formed at a plurality of locations. It is located in the free rotation range defined by the protrusion of the outer frame and allows the outer frame to rotate. Further, when the outer frame body rotates in the opposite direction, the disk-shaped rolling member moves from the free rotation region to the blocking region by the wedge action and prevents the outer frame body from rotating in the opposite direction.

The other side of the holding body 2 The inner side surface of the flange portion 2b is in contact with the one side surface 1a of the outer frame body 1. In this case, the one side flange portion 2a of the holding body 2 may be fixed to the inner peripheral surface of the outer frame body 1 by fitting such as press fitting. Further, the inner peripheral surface of the outer frame body 1 may be another number of regular polygons.

【００１０】保持体２に形成された複数個の貫通孔２ｃには、複数個、図では４個の円盤状ころがり部材３が挿入されて保持されると共に、これらのころがり部材は内輪体１０の外周に載せられ、発条４で押圧付勢されている。更に、保持体２の内周面は直接内輪体１０の外周に載せられてころがり部材３に対する軸受作用をするように構成されている。A plurality of, in the figure, four disc-shaped rolling members 3 are inserted and held in the plurality of through holes 2 c formed in the holding body 2, and these rolling members are arranged in the inner ring body 10. It is placed on the outer periphery and is biased by the spring 4. Further, the inner peripheral surface of the holding body 2 is directly placed on the outer periphery of the inner ring body 10 so as to serve as a bearing for the rolling member 3.

【００１１】外枠体１の内周面は、上記したように正八角形の多角形に形成されており、これにより内周面の隅部１ｂでころがり部材３の自由回転域αが構成され、内周面の辺部１ｃでころがり部材３が当接されて回転が阻止される阻止面βが構成される。また、外枠体１の外周面には、複数の切欠部１ｄが形成されており、回転する部材、この実施の形態ではスピニングリールのローター６に嵌合して、一体的に回転可能となっている。The inner peripheral surface of the outer frame 1 is formed into a regular octagonal polygon as described above, and the free rotation range α of the rolling member 3 is formed at the corner 1b of the inner peripheral surface. At the side portion 1c of the inner peripheral surface, the rolling member 3 is abutted to form a blocking surface β that blocks rotation. Further, a plurality of cutouts 1d are formed on the outer peripheral surface of the outer frame body 1, and the plurality of cutout portions 1d are fitted to the rotating member, which is the rotor 6 of the spinning reel in this embodiment, so as to be integrally rotatable. Has become.

【００１２】円盤状ころがり部材３は、高炭素クローム軸受鋼等の硬質材で構成され、図２のように高さ寸法Ｈより外径寸法Ｄが大きく形成されて外表面に２μｍ〜２０μ ｍ程度の厚さにニッケルメッキが施されている。また、前記発条４は、Ｎ形に屈曲形成されて一側４ａがころがり部材３の外周面に当接され、他側４ｂは保持体２の孔２ｄに嵌められている。The disk-shaped rolling member 3 is made of a hard material such as high carbon chrome bearing steel and has an outer diameter D larger than the height H as shown in FIG. 2 and has an outer surface of about 2 μm to 20 μm. Is nickel plated. The spring 4 is bent into an N shape, and one side 4a is in contact with the outer peripheral surface of the rolling member 3, and the other side 4b is fitted in the hole 2d of the holder 2.

【００１３】前記ローター６は、図示されていないハンドルの回転に連動して回転されるように、リール本体５の前側に突出した回転軸筒１１に回り止め嵌合されて支持されており、その前部はナット１３で固定されている。回転軸筒１１のローター６の内側の外周面にはカラー１２が嵌合されており、その外周に逆転防止体７が保持されている。逆転防止体７には、逆転防止爪車７ａが形成されており、係止爪８が係合可能となっている。なお、この係止爪８は、操作杆２０が操作されることによって、操作杆の先端に形成されたカム部９のカム９ａを介して逆転防止爪車７ａに係合可能又は係合不能位置に制御される。従って、逆転防止体７は、回転可能又は停止状態に保持される。そして、逆転防止体７の外周には、前記偏平型一方向クラッチの内輪体１０が回り止め嵌合される。The rotor 6 is supported by being fitted in a rotation stopper cylinder 11 projecting to the front side of the reel body 5 so as to rotate in association with rotation of a handle (not shown). Its front part is fixed by a nut 13. A collar 12 is fitted on the inner peripheral surface of the rotor 6 of the rotating shaft cylinder 11, and a reverse rotation preventive body 7 is held on the outer periphery thereof. The reverse rotation preventing body 7 is formed with a reverse rotation preventing pawl wheel 7a, and the locking pawl 8 can be engaged therewith. The locking claw 8 can be engaged or not engageable with the reverse rotation preventing claw wheel 7a via the cam 9a of the cam portion 9 formed at the tip of the operating rod when the operating rod 20 is operated. Controlled by position. Therefore, the reverse rotation preventing body 7 is held in a rotatable state or a stopped state. The inner race 10 of the flat type one-way clutch is fitted around the outer periphery of the reverse rotation preventive body 7 so as not to rotate.

【００１４】ローター６の凹陥部内への偏平型一方向クラッチの組み込みは、フェルト、皮革などの緩衝材２２を落し込んだ後、保持体２の他側フランジ部２ｂが前側になるように、円盤状ころがり部材３が挿入された保持体２と外枠体１を落し込み、かつ複数の切欠部１ｄをローターに嵌めて、止め環１７をローター６の鈎部６ｂに係止する。The flat type one-way clutch is installed in the concave portion of the rotor 6 such that the cushioning material 22 such as felt or leather is dropped and then the other side flange portion 2b of the holding body 2 is on the front side. The holder 2 in which the disk-shaped rolling member 3 is inserted and the outer frame body 1 are dropped, and a plurality of notches 1d are fitted on the rotor, and the retaining ring 17 is locked to the hook 6b of the rotor 6.

【００１５】次に、このように構成された偏平型一方向クラッチの動作を図３を参照して説明する。逆転防止体７が停止状態にある場合において、外枠体１と嵌合するローター（図示せず）が時計方向へ正回転されることにより、外枠体１も一体的に時計方向へ正回転される。この回転によって、円盤状ころがり部材３は、発条４の付勢力に抗して外枠体１の内周面の隅部１ｂからなる自由回転域αに位置され、これにより、外枠体１は内輪体１０に対して回転が可能となる。Next, the operation of the flat type one-way clutch thus configured will be described with reference to FIG. When the reverse rotation preventing body 7 is in a stopped state, the rotor (not shown) fitted to the outer frame body 1 is normally rotated clockwise, so that the outer frame body 1 is also integrally rotated normally clockwise. To be done. By this rotation, the disk-shaped rolling member 3 is positioned in the free rotation range α composed of the corner portion 1b of the inner peripheral surface of the outer frame body 1 against the urging force of the spring 4, whereby the outer frame body 1 is Can rotate with respect to the inner race 10.

【００１６】そして、ローターが反時計方向に逆回転されると、この回転で偏平型一方向クラッチの外枠体１も一体的に反時計方向へ逆回転される。この逆転動作にともない、円盤状ころがり部材３は、自由回転域α位置から、図に示すように内周面の辺部１ｃからなる阻止面βに移動されて当接され、円盤状ころがり部材３のクサビ作用で内輪体１０に対して外枠体１の逆回転が阻止される。この時、逆転防止体７は停止状態にあるから、逆転防止体７の外周に固定された内輪体１０の回転も停止されて、この結果、ローターの逆回転は停止される。When the rotor is rotated counterclockwise in the counterclockwise direction, the outer frame body 1 of the flat type one-way clutch is integrally rotated counterclockwise in the counterclockwise direction. Along with this reverse movement, the disk-shaped rolling member 3 is moved from the position of the free rotation area α to the blocking surface β composed of the side portion 1c of the inner peripheral surface as shown in the figure and brought into contact with the disk-shaped rolling member 3. The wedge action of the member 3 prevents reverse rotation of the outer frame body 1 with respect to the inner ring body 10. At this time, since the reverse rotation preventing body 7 is in a stopped state, the rotation of the inner ring body 10 fixed to the outer periphery of the reverse rotation preventing body 7 is also stopped, and as a result, the reverse rotation of the rotor is stopped.

【００１７】この逆転動作の際、円盤状ころがり部材３のクサビ作用による逆転時の遊度が少ないこと、及び逆転防止体７が予め停止状態にあることから、敏速にローターの逆回転は停止される。なお、逆転防止体７が回転可能状態にあれば、ローターは、内輪体１０及び逆転防止体７とともに一体的に逆回転が可能となる。During this reverse rotation operation, the reverse rotation of the rotor is promptly stopped because the degree of play during reverse rotation due to the wedge action of the disk-shaped rolling member 3 is small and the reverse rotation prevention body 7 is in a stopped state in advance. It If the reverse rotation preventive body 7 is in a rotatable state, the rotor can be reversely rotated integrally with the inner ring body 10 and the reverse rotation preventive body 7.

【００１８】円盤状ころがり部材３は、図２に示すように、高さ寸法Ｈより外径寸法Ｄが大きく形成されているため、一方向クラッチを少数の円盤状ころがり部材で構成することができ、また、円盤状ころがり部材３の外径寸法を大きく構成したことで円盤状ころがり部材３と外枠体１の内周面の辺部１ｃからなる阻止面β及び内輪体１０との面圧が低くなって、回転衝撃を受けても、喰い込みロックしてしまうことがないと共に伝達許容トルクの低下が避けられ、耐久性が向上する。また、円盤状ころがり部材３の数が少ないから回転力が軽くなると共に軽量化される。さらに、図の実施の形態で示すように、軸方向が薄型の製品に組み込むことが出来る。As shown in FIG. 2, the disc-shaped rolling member 3 is formed so that the outer diameter dimension D is larger than the height dimension H. Therefore, the one-way clutch should be composed of a small number of disc-shaped rolling members. In addition, since the outer diameter of the disk-shaped rolling member 3 is configured to be large, the surface of the disk-shaped rolling member 3 and the blocking surface β composed of the side portion 1c of the inner peripheral surface of the outer frame 1 and the inner ring 10 is formed. Even if the pressure becomes low and it receives a rotational impact, it will not bite and lock, and a decrease in the allowable transmission torque will be avoided, improving durability. Further, since the number of the disk-shaped rolling members 3 is small, the rotational force is light and the weight is light. Further, as shown in the illustrated embodiment, it can be incorporated into a product having a thin axial direction.

【００１９】図４は、偏平型一方向クラッチの第２の実施の形態を示す拡大断面背面図である。この実施の形態では、保持体２の内周面が内輪体１０の外周から離れていることと、円盤状ころがり部材３に貫通孔３ａが穿設されて軽量化されている点が前記第１の実施の形態と異なる。FIG. 4 is an enlarged sectional rear view showing a second embodiment of the flat type one-way clutch. In this embodiment, the inner peripheral surface of the holding body 2 is separated from the outer peripheral surface of the inner ring body 10, and the disk-shaped rolling member 3 is provided with a through hole 3a for weight reduction. Different from the embodiment.

【００２１】図５および図６で偏平型一方向クラッチの外枠体１′は、鋼板を浸炭焼き入れした硬質材を使用して絞り加工で有底筒状に形成されて底面中心に内輪体１０の外周が嵌まる透孔１ｅが穿設されると共に、外周に複数個の突出部１ｆが形成されてその内周面の隅部１ｇでころがり部材３の自由回転域αが構成され、内周面の辺部１ｈでころがり部材３が当接されて回転が阻止される阻止面βが形成されて変形多角形が構成されている。In FIGS. 5 and 6, the outer frame body 1 ′ of the flat type one-way clutch is formed into a cylindrical shape with a bottom by drawing using a hard material obtained by carburizing and quenching a steel plate, and the inner ring body is centered on the bottom surface. A through hole 1e into which the outer periphery of 10 is fitted is formed, and a plurality of protrusions 1f are formed on the outer periphery, and a corner 1g of the inner peripheral surface thereof forms a free rotation area α of the rolling member 3. A deformed polygon is formed by forming a blocking surface β on the side 1h of the inner peripheral surface against which the rolling member 3 abuts to prevent rotation.

【００２２】外枠体１′の開口には保持環２３が嵌合固定されており、その外枠体１′内には保持体２′が挿入される。保持体２′の複数個の貫通孔２ｅには複数個、図では４個の円盤状ころがり部材３が挿入されて保持されると共に、これらのころがり部材は内輪体１０の外周に載せられ、発条４′で押圧付勢されている。この発条４′は、保持体２′の外側に複数枚載せられて両側に形成された舌片４ｃの折り返しで保持体２′に取り付けられている。更に発条４′には、矩形の透孔４ｄと透孔４ｄ内側に折曲されてころがり部材３を押圧するバネ片４ｅが形成されている。なお、ころがり部材３の両側面は図６のように高さが極めて低い球面としてもよい。この第３の実施の形態の偏平型一方向クラッチのクラッチ作用は、前記第１の実施の形態とほぼ同一である。A holding ring 23 is fitted and fixed to the opening of the outer frame body 1 ', and the holding body 2'is inserted into the outer frame body 1'. A plurality of, in the figure, four disk-shaped rolling members 3 are inserted and held in the plurality of through holes 2e of the holding body 2 ', and these rolling members are placed on the outer periphery of the inner ring body 10. And is pressed and urged by the spring 4 '. A plurality of the ridges 4'are mounted on the outside of the holding body 2'and the tongue pieces 4c formed on both sides are folded and attached to the holding body 2 '.

【考案の効果】[Effect of device]

本考案によれば、円盤状ころがり部材を、高さ寸法より外径寸法を大きく形成したことによって、円盤状ころがり部材の外径寸法を大きくすることができ、これにより円盤状ころがり部材と外枠体の内周面及び内輪体との面圧をが低くすることができる。従って、回転衝撃を受けても、喰い込みロックしてしまうことがないと共に伝達許容トルクの低下が避けられ、耐久性が向上する。又、円盤状ころがり部材の数を少なくすることができるため、回転力が軽くなると共に軽量化される等、実用上優れた効果を奏する偏平型一方向クラッチを提供することが出来る。 According to the present invention, the outer diameter dimension of the disc-shaped rolling member is made larger than the height dimension, so that the outer diameter dimension of the disc-shaped rolling member can be increased. The surface pressure between the inner peripheral surface of the frame and the inner ring can be reduced. Therefore, even if it receives a rotational impact, it does not bite and lock, and it is possible to avoid a decrease in the allowable transmission torque, which improves durability. Further, since it is possible to reduce the number of disc-shaped rolling members, it is possible to provide a flat type one-way clutch which has excellent practical effects such as a reduction in rotational force and a reduction in weight.
