Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing reel one-way clutch mounting mechanism and a fishing reel one-way clutch device.

[0002]

2. Description of the Related Art In a fishing reel, in order to transmit a rotation operation of a handle to a spool around which a fishing line is wound, and in order to prevent the handle from being rotated by the rotation of the spool depending on the operating condition, A one-way clutch is incorporated in the rotation transmission mechanism from the spool to the spool.

Various structures of one-way clutches have been proposed, for example, there is a technique disclosed in Japanese Patent Publication No. 2-56528. In this conventional technique, a roller is accommodated between the shaft member and the recess formed in the inner surface of the outer ring, and the roller rolls in contact with the shaft member due to the difference in the relative rotational directions of the shaft member and the outer ring. When the roller moves to a shallow position in the recess of the outer ring, the roller is caught between the shaft member and the recess of the outer ring to transmit the rotational force, and when the roller moves to the deep position in the recess of the outer ring, the roller is free to roll. As a result, the rotational force is not transmitted between the shaft member and the outer ring. In addition, a convex portion corresponding to the concave shape of the inner surface is formed on the outer periphery of the outer ring. And, on the inner surface of the hole member for transmitting the rotational force between the shaft member, a recess corresponding to the shape of the convex portion of the outer ring is provided,
The outer ring is fitted and held in the hole member by the engagement between the convex portion of the outer ring and the recess of the hole member.

[0004]

The conventional one-way clutch described above has a problem that it is difficult to accurately align the one-way clutch and the hole member for mounting the one-way clutch. That is, in the structure described above, the outer ring and the hole member are fitted and held by engaging the convex portion on the outer periphery of the outer ring and the recess on the inner surface of the hole member. The circumferential portion provided between the convex portions of the outer ring and the circumferential portion provided between the recesses of the hole member are fitted to each other to perform the centering of the outer ring and the hole member. But,
As for the outer circumference of the outer ring, it is difficult to accurately machine the circumferential concave portion existing between the convex shapes, so that the outer ring and the hole member are likely to be misaligned.

In the fishing reel, in order to improve the operability of the fishing operation, it is required that the rotating operation of the spool by the handle can be performed lightly and smoothly. Therefore, the shaft, the outer ring and the hole member of the one-way clutch can be accurately adjusted. However, sufficient performance has not been achieved with the above-mentioned prior art. In addition, the conventional one-way clutch described above,
Although it is useful for controlling the transmission of rotational force, it can be used to give a one-way clutch a bearing function or to transmit a large radial load between a shaft member and a hole member. Is not suitable.

[0006] This is positioned in the radial direction by a plurality of rollers interposed between the shaft member and the hole member, but the core of the shaft member and the hole member is different due to variations in processing accuracy and assembly accuracy of the plurality of rollers. It is difficult to make an accurate match. Moreover,
Since each roller moves in the recess of the outer ring, the shaft member and the hole member may be misaligned during operation. If the shaft member and the hole member are misaligned with each other, the rotation is not smoothly performed, and the control function of the one-way clutch in the rotation direction is impaired.

As can be seen from the above description of the structure, since the shaft member and the hole member are connected via the roller, the load applied to the bearing, especially the large load in the radial direction, directly acts on the roller. Therefore, an excessive load may act on the roller and damage the roller. In addition, the roller may be strongly caught in the recess of the outer ring and may not return to its original state, so that the function of the one-way clutch may not be fulfilled.

Therefore, when the one-way clutch as described above is used, a bearing for connecting the shaft member and the hole member is attached at a position different from the one-way clutch, and the one-way clutch is excessively large. It was recommended to keep the load from acting. However, when the one-way clutch is incorporated in a small mechanical device such as a fishing reel, it is difficult to provide sufficient space for mounting both the one-way clutch and the bearing. Therefore, it is unavoidable in the past.
In many cases, the one-way clutch is also used as the bearing, and there have been problems that the durability of the one-way clutch is impaired and the one-way rotation cannot be controlled smoothly.

An object of the present invention is, in a fishing reel one-way clutch mounting mechanism, centering a one-way clutch and a hole member for mounting the one-way clutch without impairing the one-way rotation control function of the one-way clutch. To be able to do exactly. In a fishing reel one-way clutch device, one-way rotation control can be favorably performed, and a function as a bearing can also be favorably performed to achieve miniaturization.

[0010]

SUMMARY OF THE INVENTION A one-way clutch mounting mechanism according to a first aspect of the present invention comprises a one-way clutch for fishing, in which a plurality of engagement projections extending in the axial direction are arranged on the outer circumference of the one-way clutch at intervals along the circumferential direction. It is a mechanism that is attached to a hole body included in the rotation transmission system of the reel, and includes a detent engagement portion and a fitting circular hole portion. The detent engagement portion is arranged on the inner circumference of the hole body, is movable in the radial direction relative to the engagement projection of the one-way clutch, and is engaged in the circumferential direction. The fitting circular hole portion is arranged on the inner periphery of the hole body on the side of the detent engagement portion, and is fitted to the outer periphery of the engagement protrusion of the one-way clutch.

A two-way clutch device according to a second aspect of the present invention is a one-way clutch device provided in a rotation transmission system of a fishing reel, and includes a shaft body and a hole body, a plurality of rollers, a cylindrical roller retainer, and a bearing ring. And a one-way clutch including an outer ring portion, a detent engagement portion, and a fitting circular hole portion. The shaft body and the hole body are included in the rotation transmission system. The one-way clutch is arranged between the shaft body and the hole body. The rollers contact the outer circumference of the shaft body and are arranged at intervals along the circumferential direction.
The roller retainer has a plurality of holding holes which are arranged on the outer periphery of the shaft body with a space between the roller holder and the shaft body, and each of which holds a plurality of rollers. The bearing ring is rotatably fitted to the outer periphery of the shaft body on the side of the roller holder, and is fixedly connected to the roller holder in the circumferential direction. The outer ring portion is arranged on the inner circumference of the hole body, accommodates the roller and the roller retainer, and is fixed to the bearing ring. Each of the plurality of rollers is accommodated and the cam becomes shallower from one circumferential direction to the other. It has a concave portion on the inner circumference and has a plurality of engaging projections on the outer circumference which extend in the axial direction and are arranged at intervals along the circumferential direction. The detent engagement portion is arranged on the inner circumference of the hole body, is movable in the radial direction relative to the engagement projection of the one-way clutch, and is engaged in the circumferential direction. The fitting circular hole portion is arranged on the inner periphery of the hole body on the side of the detent engagement portion, and is fitted to the outer periphery of the engagement protrusion of the one-way clutch.

In the fishing reel one-way clutch device of the invention 3, the fishing reel has a rotation transmission system between the spool around which the fishing line is wound and the handle for rotating the spool. The bearing ring of the one-way clutch is arranged closer to the handle than the roller and the roller holder in the rotation transmission system.

[0013]

In the fishing reel one-way clutch mounting mechanism according to the first aspect of the present invention, the engaging action of the detent engagement portion disposed on the inner periphery of the hole body and the engagement protrusion of the one-way clutch causes the one-way clutch to engage with the hole body. Since the directional clutch is fixed in the circumferential direction, the one-way clutch and the hole do not slip in the rotational direction, and a large rotational force can be reliably transmitted.

Moreover, by fitting the fitting circular hole of the hole and the outer periphery of the engaging projection of the one-way clutch, the centering of the hole and the one-way clutch can be easily and accurately performed. This is because it is easy to process with the fitting circular hole portion of the hole body accurately centered, so if the fitting circular hole portion accurately centered is fitted to the one-way clutch. The hole body and the one-way clutch are accurately aligned with each other.

In the fishing reel one-way clutch device according to the second aspect of the invention, the detent engagement portion and the fitting circular hole portion arranged on the inner circumference of the hole body of the rotation transmission system to which the one-way clutch device is attached, and the one-way clutch device. The engagement protrusion provided on the outer ring portion of the clutch performs the same function as in the first aspect. Further, since the outer ring portion arranged on the inner circumference of the hole body is fitted and held on the shaft body through the bearing ring, the load acting between the shaft body and the hole body is transmitted from the outer ring portion to the bearing ring. Therefore, it is possible to prevent an excessive load from acting on the roller. Since the centering of the bearing ring and the shaft can be performed exactly as in the normal bearing mechanism,
Alignment of the one-way clutch and the shaft is good.

In the fishing reel one-way clutch device according to the third aspect of the present invention, the bearing ring of the one-way clutch is arranged closer to the handle than the roller and the roller retainer in the rotation transmission system. Is transmitted to the outer ring portion via the bearing ring closer to the handle than the roller and the roller retainer, and it is difficult to apply an excessive load to the roller and the roller retainer. Conversely, even when a force is transmitted from the hole body to the handle side via the shaft body, it is difficult to apply an excessive load to the roller and the roller retainer.

The torque is transmitted to or released from 0. Since the cylindrical hole portion 160 is fixed, if the rotational force of the inner shaft cylinder 110 is transmitted to the cylindrical hole portion 160, the rotation of the inner shaft cylinder 110 is blocked. When the inner barrel 110 is rotated in the opposite direction, the rotational force is not transmitted to the barrel hole 160, and the inner barrel 110 can freely rotate. In other words, the one-way clutch mechanism,
It is used as a reverse rotation prevention mechanism that allows the inner shaft cylinder 110 to rotate only in one direction.

As shown in FIGS. 3 to 6, a plurality of cylindrical rollers 120 are in contact with the circumferential surface of the inner shaft cylinder 110 and six rollers 120 are arranged at equal intervals along the circumferential direction. . The roller 120 is made of wear-resistant steel or the like. A roller holder 130 made of a resin such as polyacetal or polyamide is arranged on the outer periphery of the inner cylinder 110.
The roller holder 130 is a tubular body having an inner diameter larger than the outer diameter of the inner shaft cylinder 110.

As shown in detail in FIG. 6, the roller holder 1
30 has substantially rectangular roller holding holes 132 at equal intervals along the circumferential direction, and the rollers 120 are housed in the respective roller holding holes 132. A roller retainer 170 is provided on the inner wall of the roller holding hole 132 in the circumferential direction. In the roller retainer 170, elastically deformable blade pieces are V-shaped, and the left and right ends of the roller retainer 170 abut the roller 120 accommodated in the roller holding hole 132, and the opposite side to the roller 120. Apply an urging force toward the inner wall of.

A bearing ring 150 is arranged on the side of the roller holder 130. The bearing ring 150 is made of a normal bearing material. The inner diameter of the bearing ring 150 is the inner cylinder 11
The outer diameter is almost the same as 0, and the inner shaft cylinder 110 slides and rotates in a state of being fitted to the bearing ring 150. An engaging protrusion 154 that protrudes in the axial direction is provided on the side surface of the bearing ring 150 on the roller 120 side, and an engaging concave groove 134 is formed on the side surface of the roller holder 130 on the bearing ring 150 side. Then, the engaging protrusion 154 of the bearing ring 150
Engaging with the engaging groove 134 of the roller holder 130, the bearing ring 150 and the roller holder 130 are fixedly connected in the circumferential direction.

A cylindrical outer ring portion 140 is arranged on the outer periphery of the roller 120, the roller holder 130 and the bearing ring 150. The outer ring portion 140 is formed by pressing a thin metal plate into a cup shape. The side ring portion 141 arranged at one end of the outer ring portion 140 in the axial direction contacts the side surface of the roller holder 130. The outer periphery of the bearing ring 150 is press-fitted into the other axial end of the outer ring portion 140 to be fitted and fixed to each other. An engaging groove 146 is formed at the side end of the outer ring portion 140, and an engaging protrusion 152 is formed on the outer periphery of the bearing ring 150. By engaging these, the outer ring portion 140 and the bearing ring 150 are formed. And are securely fixed to each other in the circumferential direction.

A plurality of cam-shaped recesses 142 are provided on the inner surface of the outer ring portion 140 at equal intervals in the circumferential direction. The outer peripheral portion of the roller 120 is housed in each cam-shaped recess 142. As shown in FIG. 4, the cam-shaped recess 142
Is shallower from one side to the other side in the circumferential direction. At the shallow portion of the cam-shaped concave portion 142, the gap between the outer periphery of the inner shaft cylinder 110 and the inner surface of the cam-shaped concave portion 142 is set to be smaller than the diameter of the roller 120, and when the roller 120 is arranged at this portion. , The outer periphery of the inner shaft cylinder 110 and the cam-shaped recess 1
The roller 120 is engaged with the inner surface of the roller 42. At a deep portion of the cam-shaped recess 142, the gap between the outer circumference of the inner shaft cylinder 110 and the inner surface of the cam-shaped recess 142 is set to be larger than the diameter of the roller 120, so that the roller 120 can freely roll.

On the outer peripheral surface of the outer ring portion 140, there is provided an engaging projection 144 having a convex shape substantially the same as the shape of the cam-shaped concave portion 142 on the inner surface. The engaging projection 144 is formed by swelling the metal thin plate, which is the material of the outer ring portion 140, to the outer peripheral side according to the shape of the cam-shaped recess 142 on the inner surface when the outer ring portion 140 is manufactured by press working. . Outer ring 140
Is inserted into the inner circumference of the cylindrical hole 160.

As shown in detail in FIG. 4, in the inner periphery of the cylindrical hole portion 160, a detent engagement portion composed of a convex ridge 164 and a concave groove 162 extending in the axial direction is provided from one end in the axial direction to a midpoint. Have. The outer ring portion 14 is provided in the concave groove 162 of the detent engagement portion.
The engaging protrusion 144 of 0 enters, and the circumferential end of the engaging protrusion 144 abuts on the peripheral edge portion of the concave groove 162 of the detent engagement portion, whereby the outer ring portion 140 and the cylindrical hole portion 160 are fixedly engaged. To do. The inner peripheral diameter of the concave groove 162 of the cylindrical hole portion 160 is larger than the outer peripheral diameter of the engaging protrusion 144 of the outer ring portion 140, and the cylindrical hole is larger than the outer diameter of the valley portion formed between the engaging protrusions 144 of the outer ring portion 140. The inner diameter of the ridge 164 of the portion 160 is larger.
At the portion where the engagement protrusion 144 and the detent engagement portions 162, 164 engage, the outer periphery of the outer ring portion 140 and the cylindrical hole portion 16
There is a gap in the radial direction from the inner circumference of 0. Therefore, the engagement protrusions 144 and the detent engagement portions 162, 16
In the engagement portion with 4, the outer ring portion 140 and the cylindrical hole portion 160 are not positioned in the radial direction, that is, centered.

As shown in detail in FIG. 5, a circular hole portion 166 is provided on the inner periphery of the cylindrical hole portion 160 on the side where the detent engagement portions 162, 164 are not provided. The inner diameter of the circular hole portion 166 corresponds to the outer peripheral diameter of the engaging protrusion 144 of the outer ring portion 140, and the circular hole portion 166 is fitted to the outer periphery of the engaging protrusion 144. By fitting the circular hole portion 166 and the outer periphery of the engaging protrusion 144, the cylindrical hole portion 160 and the outer ring portion 140 are aligned with each other.

In order to mount the one-way clutch mechanism having the above structure between the inner shaft cylinder 110 and the cylindrical hole 160, the roller 120 and the roller retainer 1 are provided inside the outer ring 140.
When the bearing ring 150 is press-fitted from the side of the outer ring portion 140 after housing 30,
0 and the roller holder 130 are engaged and assembled integrally. [Drag Mechanism] The drag mechanism 60 of the rotation restricting mechanism 22
Presses the inner shaft cylinder 110 of the one-way clutch mechanism 100 against the main gear 31. If the rotation direction of the main gear 31 matches the rotation blocking direction of the one-way clutch mechanism 100, the rotation of the main gear 31 is blocked. However, when a large force is applied to the main gear 31, the inner shaft cylinder 110
The main gear 31 rotates due to the occurrence of slippage at the pressure contact point between the main gear 31 and the main gear 31. When the brake adjusting knob 3 is rotated, the urging force of a spring that is built in the drag mechanism 60 and acts in the axial direction to adjust the urging force is adjusted, and the pressure contact force from the inner shaft cylinder 110 to the main gear 31 is increased or decreased. As a result, the resistance force to the rotation of the main gear 31, that is, the drag force changes. [Description of Basic Operation] When the clutch mechanism 21 is operated by the thumb rest 17 to put it in the clutch-off state, the spool 15 can freely rotate and the fishing line can be fed. At this time, the rotation of the spool 15 is not transmitted to the main gear 31 and the handle 2.

If there is a fish spread, the clutch mechanism 21 is turned on by the thumb rest 17 and the handle 2 is rotated in the winding direction. The rotational force from the handle 2 is transmitted to the spool shaft 25 and the spool 15 via the handle shaft 30, the main gear 31, and the pinion 32, so that the fishing line can be wound up. [Operation of the one-way clutch mechanism] When the fishing line is pulled out by pulling the fish, the spool 15 rotates, and the rotation of the spool 15 is transmitted to the main gear 31 via the pinion gear 32. The rotation of the main gear 31 is transmitted to the inner barrel 110 of the one-way clutch mechanism 100 via the drag mechanism 60.

4 and 5, the inner shaft cylinder 110 rotates in the X direction with respect to the cylindrical hole 160. The roller 120 that contacts the outer circumference of the inner shaft cylinder 110 rolls as the inner shaft cylinder 110 rotates. The roller 120 moves in the roller holding hole 132 of the roller holder 130 in the X direction. When the roller 120 moves the cam-shaped recess 142 of the outer ring portion 140 to the shallower side, the roller 120 is caught between the cam-shaped recess 142 and the inner shaft cylinder 110, and the roller 120 cannot roll any further. The inner cylinder 110 and the outer ring portion 140 are integrally fixed via the roller 120. The rotational force of the inner shaft cylinder 110 is transmitted to the outer ring portion 140 via the rollers 120. By engaging the engagement protrusions 144 of the outer ring portion 140 with the detent engagement portions 162, 164 of the cylindrical hole portion 160, the outer ring portion 1
The rotational force transmitted to 40 is reliably transmitted to the cylindrical hole 160. Since the cylindrical hole portion 160 is fixed, the outer ring portion 1
40, that is, the rotation of the inner barrel 110 and the main gear 31 is blocked. The rotation of the spool 15 is blocked, and a drag force, that is, a drag force acts on the pulling of the fish.

Since the bearing ring 150 is slidably fitted to the outer circumference of the inner shaft cylinder 110, the inner shaft cylinder 110, that is, the handle shaft 30, is bearing-supported in the cylindrical hole portion 160 via the bearing ring 150 and the outer ring portion 140. To be done. When a radial load is applied to the handle shaft 30, the load is supported by the bearing action between the bearing ring 150 and the inner shaft cylinder 110. Since the load is supported by the bearing ring 150, the roller 120
There is no excessive load on the.

Next, the case where the handle 2 is rotated to wind up the fishing line will be described. In this case, the inner shaft cylinder 110 is rotated in the Y direction with respect to the cylindrical hole 160 in FIGS. When the roller 120 rolls, the cam-shaped recess 14
Move to the deeper part of 2. If the roller 120 is arranged at a deep position of the cam-shaped recess 142, the roller 120 can freely roll, so that no rotational force is transmitted from the inner shaft cylinder 110 to the outer ring portion 140. Inner shaft 110 and handle shaft 3
The rotation of 0 is not blocked, and it can be freely rotated, so that the fishing line can be smoothly wound.

At this time, the roller 120 holds the roller holder 17
0 is elastically deformed. Therefore, when the rotation of the handle 2 is stopped to stop the rotation of the inner barrel 110 in the Y direction, or when the fish is pulled, the inner barrel 110 rotates in the X direction.
Roller retainer 1 immediately when switching to the direction of rotation
The roller 120 can be moved from the deep position of the cam-shaped recess 142 to the central or shallow position by the urging force of 70. As a result, the drag force is immediately applied to the fishing line,
You can prevent the fishing line from being drawn too much.

If an excessive load is applied to the roller 120, the roller 120 may largely deform the roller retainer 170, damage the roller retainer 170, or prevent the roller 120 from returning to its original position. Therefore, conventionally, the roller retainer 170 or the roller retainer 17 is used.
A deformation prevention structure for preventing excessive deformation of the roller retainer 170 has been provided on the inner wall of the roller holding hole 132 with which 0 contacts. However, in this embodiment, as described above, since an excessive load does not act on the roller 120, the roller retainer 17 as described above is used.
No special deformation prevention structure for 0 is provided. Other Embodiments (a) The basic structure of each member constituting the one-way clutch mechanism 110, the roller 120, the roller retainer 130, the outer ring portion 140, etc. is the same as that of a normal one-way clutch device.

(B) The one-way clutch mechanism 110 is incorporated between the inner shaft cylinder 110 and the cylinder hole 160 as described above, and also exhibits the one-way rotation function of the rotation transmitting mechanism 20 of the fishing reel. It can be incorporated at any effective position. Specifically, in the combination of the hole body and the shaft body, a place where one rotation is transmitted to the other and both can be rotated, or one of the hole body and the shaft body is fixed and the other is prevented from reversing. Can be incorporated into the part that fulfills

(C) In the above-described embodiment, the engaging projection 144 on the outer circumference of the outer ring portion 140 has a shape corresponding to the cam-like recess 142 on the inner circumference. However, the shape of the engaging projection 144 is the cam-like recess. The shape of 142 does not have to correspond exactly. The engagement structure of the engagement protrusion 144 of the outer ring portion 140 and the rotation stop engagement portions 162, 164 of the cylindrical hole portion 160 is such that they can be relatively moved in the radial direction and are engaged in the circumferential direction. For example, the shapes and structures of the engaging portions of various engaging structures in ordinary mechanical devices can be applied. For example, a normal spline engagement structure can be adopted.

(D) As in the above-mentioned embodiment, the engaging protrusion 144 of the outer ring portion 140 and the rotation stopping engaging portion 1 of the cylindrical hole portion 160.
If 62 and 164 are provided over the entire circumference in the circumferential direction, the engaging action in the circumferential direction is exhibited in a well-balanced manner. However, the engaging protrusion 144 and the detent engaging portions 162, 164 may be provided only in a part of the circumferential direction. (e) Anti-rotation engaging portion 16 on the inner circumference of the cylindrical hole 160
2, 164 and the fitting circular hole portion 166 are arranged on the side closer to the bearing ring 150 as in the above-described embodiment.
6 is arranged, the cylindrical hole portion 1 through the bearing ring 150.
The centering of 60 and the inner cylinder 110 can be accurately performed. However, the fitting circular hole portion 166 may be arranged on the side far from the bearing ring 150.
