Description
【0001】[0001]
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、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]
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.

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.

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.

【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.

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.

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.
