Description

【0001】
【発明の属する技術分野】
本発明は転がり式一方向クラッチを利用した魚釣用スピニングリールの逆転防止装置の改良に関する。
【0002】
【従来の技術】
魚釣用スピニングリールの逆転防止装置として、ハンドルと連動する駆動軸とリール本体との間に転がり式一方向クラッチを設け、転がり部材の楔作用を利用して逆転遊度を少なくして駆動軸の逆転を防止することが特開平9−205947号公報等で知られている。
【0003】
【発明が解決しようとする課題】
ところで従来の転がり式一方向クラッチは、転がり部材を保持する保持器を内部に収容した外輪がリール本体に一体的に固定され、前記保持器内に駆動軸に回り止め嵌合された内輪が前記転がり部材に摺接可能に嵌合されると共に該内輪は駆動軸に螺子等で移動しないように固定されている。
【0004】
また駆動軸の外周及び内輪の内周は断面非円形に形成されて回り止め嵌合されているが、この回り止め嵌合部には加工精度上の微小の回転遊度が生じこの回転遊度のため駆動軸に螺子等で固定されている内輪は駆動軸に対して同芯精度が得られず偏芯して固定されることにより、一方向クラッチの転がり部材との接触作用が不均一となり、安定した楔作用による逆転防止機能が得られなくなったり、回転が重くなったり、部分的に引掛り現象が生じたり、耐久性を低下したりする問題点がある。
【0005】
本発明はこのような欠陥を改善して、駆動軸に嵌合して一体回転する転がり式一方向クラッチの内輪を軸方向に遊度をもたせて保持せしめることにより、転がり部材との接触作用を均一にして転がり部材による楔作用を安定せしめ逆転防止機能を向上するようにした魚釣用スピニングリールの逆転防止装置を提供することを目的とするものである。
【0006】
【課題を解決するための手段】
本発明は前記目的を達成するために、ハンドルで回動される駆動軸と該駆動軸の外側におけるリール本体との間に転がり式一方向クラッチを介在せしめて前記駆動軸の逆転を前記一方向クラッチの転がり部材の楔作用によって防止するようにした魚釣用リールにおいて、前記駆動軸の外周に一体的に回動するように嵌合しかつ前記一方向クラッチの転がり部材に摺接する内輪を、駆動軸の軸方向に微小範囲で移動可能の遊度をもたせて保持せしめると共に前記内輪の一端部を駆動軸に固着したローターに一体的に回動するように回り止め係合したことを特徴とするものである。
【0007】
【発明の実施の形態】
本発明の実施の形態を魚釣用スピニングリールにおける実施例の図面について説明すると、ハンドル1′を有するハンドル軸1と公知のように駆動歯車2、ピニオン2′を介して連動される中空状駆動軸3には、前端部に螺子Sでローター4が締結固着されると共にリール本体5の前部に支持されており、更に前記駆動軸3内には先端部にスプール6を有するスプール軸7が挿通され、前記ハンドル軸1の回動と連動して公知の摺動機構8により前後往復摺動するように構成されている。
【0008】
また前記駆動軸3のリール本体5に対する支持部には、リール本体5との間に転がり式一方向クラッチ9が装着されており、該転がり式一方向クラッチ9は、リール本体5に固着された外輪10と、その内側に位置している内部に転がり部材11を収容した保持器12と、駆動軸3に回動自在に嵌着され、ローター4を介して、螺子Sで該駆動軸3上に挟着固定されたカラー13の外周面に回動可能に嵌合した内輪14と、前記保持器12に係合して前記転がり部材11を楔作用する作動位置と楔作用しない非作動位置に切換制御する操作部材15とより構成され、更に前記内輪14は駆動軸3の軸方向に微小範囲で移動可能の遊度Xをもたせて保持すると共に内輪14の前端部と駆動軸3に固着されたローター4とは凹凸係合部4′・14′によって回り止め係合している。
【0009】
本発明の実施例は上記のように構成されているので、操作部材15により転がり部材11を楔作用する作動位置に切換えた状態で、ローター4が逆転しようとすると、これと回り止め係合して一体的に逆転しようとする内輪14は転がり部材11の楔作用によってその逆転を阻止されるものであるが、この場合駆動軸3と内輪14との間の加工精度上の誤差によって発生する偏芯、振れ等は内輪14の軸方向の遊度Xによって吸収され、転がり部材11と内輪14との接触作用を均一に保持して転がり部材11が安定した楔作用を行い、逆転を防止するものである。
【0010】
図6に示す実施例は、前記実施例において、内輪14を駆動軸3に嵌合したカラー13を介して嵌着することなく、これを省略して直接駆動軸3の小径部3″にローター4を軸方向に移動しないように嵌着して螺子Sで締結固定すると共に内輪14を軸方向に移動可能に嵌着したものであり、更に図7に示す実施例は、内輪14を直接駆動軸3の外周に非円形部3′によって軸方向に遊度を保持させて回り止め嵌合したものである。
【0011】
【発明の効果】
本発明は魚釣用スピニングリールにおいて一方向クラッチを構成する転がり部材に摺接する内輪を駆動軸上において軸方向に微小範囲で移動可能の遊度をもたせて保持すると共に内輪の一端部を駆動軸に一体的に回転するように回り止め嵌合して、魚釣用スピニングリールの逆転を阻止するようにしたので、加工時の精度誤差によって生じた駆動軸に対する内輪の偏芯、振れ等を内輪の軸方向の遊度で吸収し転がり部材と内輪との接触作用を均等に保持し、転がり部材の円滑かつ安定した楔作用によって逆転止め作用を行なうことができると共に駆動軸の回転性能も支障なく確実に行うことができる優れた効果を有するものである。

BACKGROUND OF THE INVENTION
The present invention relates to an improvement in a reverse rotation prevention device for a fishing spinning reel using a rolling one-way clutch.
[0002]
[Prior art]
As an anti-reversal device for spinning reels for fishing, a rolling one-way clutch is provided between the drive shaft interlocked with the handle and the reel body, and the drive shaft is reduced by using the wedge action of the rolling member to reduce the reverse play. It is known in Japanese Patent Application Laid-Open No. 9-205947 and the like to prevent the reverse rotation.
[0003]
[Problems to be solved by the invention]
By the way, in the conventional rolling type one-way clutch, an outer ring that accommodates a retainer that holds a rolling member is integrally fixed to a reel body, and an inner ring that is non-rotatably fitted to a drive shaft is fitted in the retainer. The inner ring is fitted to the rolling member so as to be slidable, and the inner ring is fixed to the drive shaft by a screw or the like.
[0004]
Also, the outer periphery of the drive shaft and the inner periphery of the inner ring are formed in a non-circular cross section and are fitted with a non-rotating fit. For this reason, the inner ring fixed to the drive shaft with screws or the like cannot be concentric with the drive shaft and is fixed eccentrically, so that the contact action with the rolling member of the one-way clutch becomes uneven. There is a problem that the function of preventing the reverse rotation by the stable wedge action cannot be obtained, the rotation becomes heavy, the catching phenomenon is partially generated, and the durability is lowered.
[0005]
The present invention improves such a defect, and by holding the inner ring of the rolling type one-way clutch that fits on the drive shaft and rotates integrally with the axial direction, the contact action with the rolling member is achieved. It is an object of the present invention to provide an anti-reverse device for a spinning reel for fishing, which is made uniform to stabilize the wedge action by the rolling member and to improve the reverse-rotation prevention function .
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a one-way reversal of the drive shaft by interposing a rolling one-way clutch between a drive shaft rotated by a handle and a reel body outside the drive shaft. In the fishing reel that is prevented by the wedge action of the clutch rolling member, an inner ring that is fitted to the outer periphery of the drive shaft so as to rotate integrally and is in sliding contact with the rolling member of the one-way clutch, It is characterized in that it is held with a play that can move in a minute range in the axial direction of the drive shaft, and that one end of the inner ring is engaged with a rotor fixed to the drive shaft so as to rotate integrally. To do.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described with reference to the drawings of an embodiment of a spinning reel for fishing. A hollow drive linked to a handle shaft 1 having a handle 1 'via a drive gear 2 and a pinion 2' as is well known. A rotor 4 is fastened and fixed to the front end portion of the shaft 3 by a screw S and is supported by the front portion of the reel body 5. Further, a spool shaft 7 having a spool 6 at the tip end portion is provided in the drive shaft 3. It is inserted and is configured to slide back and forth by a known sliding mechanism 8 in conjunction with the rotation of the handle shaft 1.
[0008]
A rolling type one-way clutch 9 is mounted between the drive shaft 3 and the reel main body 5 with respect to the reel main body 5. The rolling type one-way clutch 9 is fixed to the reel main body 5. An outer ring 10, a cage 12 that accommodates a rolling member 11 inside the outer ring 10, and a drive shaft 3 are rotatably fitted on the drive shaft 3. An inner ring 14 that is rotatably fitted to the outer peripheral surface of the collar 13 that is clamped and fixed thereto, and an operating position that engages the retainer 12 to wedge the rolling member 11 and a non-operating position that does not wedge. Further, the inner ring 14 is held with a play X that is movable in a minute range in the axial direction of the drive shaft 3 and is fixed to the front end portion of the inner ring 14 and the drive shaft 3. The rotor 4 has a concave / convex engaging portion 4 '/ 14. Are engaged detent engaged by.
[0009]
Since the embodiment of the present invention is configured as described above, when the rotor 4 tries to reversely rotate in the state where the operation member 15 switches the rolling member 11 to the operating position where the rolling member 11 acts, the rotor 4 is engaged with the rotation prevention. In this case, the reverse rotation of the inner ring 14 to be reversed integrally is prevented by the wedge action of the rolling member 11. In this case, however, the deviation caused by the error in machining accuracy between the drive shaft 3 and the inner ring 14 occurs. Core, runout, etc. are absorbed by the axial play X of the inner ring 14, and the rolling member 11 performs a stable wedge action by maintaining the contact action between the rolling member 11 and the inner ring 14 to prevent reverse rotation. It is.
[0010]
In the embodiment shown in FIG. 6, the inner ring 14 is not fitted through the collar 13 fitted to the drive shaft 3 in the above embodiment, and this is omitted and the rotor is directly attached to the small diameter portion 3 ″ of the drive shaft 3. 4 is fixed so that it does not move in the axial direction and is fastened and fixed by a screw S, and the inner ring 14 is fitted so as to be movable in the axial direction, and the embodiment shown in FIG. A non-circular portion 3 ′ is used to keep the degree of play in the axial direction on the outer periphery of the shaft 3, and to prevent rotation.
[0011]
【The invention's effect】
The present invention holds an inner ring that is in sliding contact with a rolling member that constitutes a one-way clutch in a fishing spinning reel with a degree of play that can be moved in a small range in the axial direction on the drive shaft, and at one end of the inner ring as a drive shaft. Since the rotation of the spinning reel for fishing is prevented by rotating it so that it rotates integrally with the inner ring, the eccentricity and runout of the inner ring with respect to the drive shaft caused by the accuracy error during processing are prevented. The contact of the rolling member and the inner ring is evenly absorbed by the axial play of the roller, and the reverse rotation can be prevented by the smooth and stable wedge action of the rolling member, and the rotational performance of the drive shaft is not hindered. It has an excellent effect that can be reliably performed.
