Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a one-way clutch, and more particularly to a first rotating part and a first rotating part of a fishing reel.
It is provided between the second component arranged on the inner peripheral side of the component,
The present invention relates to a fishing reel one-way clutch for inhibiting relative rotation of both components in one direction.

[0002]

2. Description of the Related Art Spinning reels, dual-bearing reels, single-bearing reels, and other fishing reels often include rotating parts such as rotors, spools, and handles that rotate relative to the reel body and other parts. . In some rotating components of this type of fishing reel, a one-way clutch is mounted in order to prohibit the rotation in the line feeding direction. In particular, in order to reduce the time lag when switching from the reverse rotation allowed state or the reverse rotation prohibited state to the reverse state, in recent years,
Roller type one-way clutches are widely used.

For example, a spinning reel uses a one-way clutch for inhibiting the rotation of the rotor in the yarn feeding direction, and a double-bearing reel and a single-bearing reel have a one-way clutch.
A one-way clutch is used to prohibit rotation of the spool in the line feeding direction. This type of roller-type one-way clutch includes an outer ring, an inner ring that is arranged on the inner peripheral side of the outer ring with a space, and a rolling element that is arranged so as to be able to contact both wheels.

Generally, fishing reels are used in an atmosphere in which water is likely to adhere and corrode, so it is desired to improve the corrosion resistance of the one-way clutch. BACKGROUND ART Conventionally, in order to improve the corrosion resistance of a one-way clutch, rust-resistant stainless steel has been used as a material for the one-way clutch used in a fishing reel particularly used for sea fishing. Among these stainless steels, hardened SUS440C is often used for the rolling elements of the one-way clutch in consideration of rotation performance and cost. That is,
This is because the SUS440C has high strength, sufficient impact resistance, sufficient specifications as a one-way clutch, and high machining accuracy.

[0005]

[Problems to be Solved by the Invention] However, SUS440
C is harder than austenitic stainless steel such as SUS304 and SUS316, but has a problem of low corrosion resistance. Therefore, it is conceivable to make the one-way clutch itself a waterproof structure in order to prevent corrosion. In order to make the one-way clutch waterproof, it is conceivable to install a rubber seal member in the gap between the inner ring and the outer ring so as to contact them. However, in such a structure, since the seal member comes into contact with the inner and outer rings, there is a possibility that the load of rotation increases and the rotation performance deteriorates.

An object of the present invention is to suppress deterioration of rotational performance and improve corrosion resistance of a one-way clutch.

[0007]

A one-way clutch for a fishing reel according to a first aspect of the present invention is provided between a relatively rotating first component of a fishing reel and a second component disposed on the inner peripheral side of the first component. A clutch that is provided to prohibit relative rotation of both components in one direction, and includes an inner ring, an outer ring, and a plurality of rolling elements. The inner ring is attached to the first component. The outer ring is attached to the second component and is arranged on the recovery side of the inner ring with a gap. The plurality of rolling elements are arranged between the wheels so as to be in contact with the wheels at intervals in the circumferential direction. A cam surface is formed on either the inner ring or the outer ring so that the rolling element can bite between the two wheels, and at least the rolling element among the inner ring, the outer ring and the rolling element is made of a highly corrosion resistant material or a metal material coated with a highly corrosion resistant coating. It is made.

In this one-way clutch, when the two parts rotate relative to each other in one direction, the rolling elements come into contact with each other and bite into the rolling cam surface to prohibit rotation in one direction. Further, when relatively rotating in the other direction, the rolling elements are separated from the cam surface and revolve while rotating on their own axes so that both wheels can rotate relative to each other. Here, at least the rolling element is made of a highly corrosion-resistant material or a metal coated with a highly corrosion-resistant coating, so that the corrosion resistance of the rolling element becomes high. Therefore, the corrosion resistance of the entire one-way clutch is improved. Further, since the corrosion resistance is improved, it is not necessary to provide a seal member for preventing corrosion. Therefore, it is possible to suppress the deterioration of the rotation performance.

A one-way clutch for a fishing reel according to a second aspect of the present invention is the clutch according to the first aspect, further comprising an urging member for urging the rolling element in a rotation permitting direction. In this case, since the rolling elements are urged in the rotation permissible direction, when the rotation direction changes from the rotation prohibited direction to the rotation permissible direction, the rolling elements easily separate from the cam surface, and the relative rotation of both wheels is instantaneously made. Acceptable.

A fishing reel one-way clutch according to a third aspect of the present invention further includes a holding member made of a highly corrosion-resistant material or a metallic material coated with a highly corrosion-resistant coating for holding the biasing member in the clutch according to the second aspect. In this case,
Since the holding member with which the rolling element may also come into contact has high corrosion resistance, the rolling of the rolling element is not hindered by the corrosion of the holding member.

A one-way clutch for a fishing reel according to a fourth aspect of the present invention is the clutch according to any one of the first to third aspects, wherein at least the rolling element is made of ceramic. In this case, at least the corrosion resistance of the rolling elements can be maintained higher due to the ceramic that does not corrode. A one-way clutch for a fishing reel according to a fifth aspect of the present invention is the clutch according to any one of the first to third aspects, wherein at least the rolling elements are made of a stainless alloy coated with a highly corrosion resistant coating. In this case, even if the high-corrosion resistant coating is peeled off, it will not easily corrode.

A fishing reel one-way clutch according to a sixth aspect of the present invention is the clutch according to the fifth aspect, wherein the high corrosion-resistant coating is formed by modifying the surface of a stainless alloy. In this case, since the high corrosion resistant coating is formed by modifying the surface of the stainless alloy, the high corrosion resistant coating is less likely to peel off as compared with plating or coating treatment. Further, if the plating or coating treatment is performed later, the roundness of the base material may be impaired due to the processing accuracy thereof, but the roundness of the base material is not easily impaired by the modification treatment.

A fishing reel one-way clutch according to a seventh aspect of the present invention is the clutch according to the sixth aspect, wherein at least the rolling elements are made of SUS440C, which is a low corrosion resistant material. In this case, the base material is inferior in corrosion resistance, but the specific strength of the base material is high and the life of the one-way clutch is long. Invention 8
A one-way clutch for a fishing reel according to the present invention is the clutch according to any one of inventions 1 to 7, wherein an outer ring is non-rotatably mounted on a reel body of a spinning reel as a fishing reel, and an inner ring is a rotor of the spinning reel. It is mounted non-rotatably. In this case, the corrosion resistance of the one-way clutch that prohibits the reverse rotation (rotation in the yarn feeding direction) of the rotor of the spinning reel can be improved while suppressing the deterioration of the rotation performance.

A one-way clutch for a fishing reel according to a ninth aspect of the present invention is the clutch according to any one of the first to seventh aspects, wherein an outer ring is non-rotatably mounted on a rotor of a spinning reel as a fishing reel, and an inner ring is It is non-rotatably mounted on a braking unit that brakes the rotor. In this case, the corrosion resistance of the one-way clutch that inhibits the reverse rotation of the rotor of the lever brake type spinning reel can be improved while suppressing the deterioration of the rotational performance.

A one-way clutch for a fishing reel according to a tenth aspect of the present invention is the clutch according to any one of the first to seventh aspects, wherein the outer ring is non-rotatably mounted on the reel body of a dual bearing reel as the fishing reel. Is non-rotatably mounted on a handle shaft rotatably mounted on the reel body. In this case, it is possible to improve the corrosion resistance of the one-way clutch that inhibits the rotation of the spool of the dual-bearing reel in the yarn feeding direction while suppressing deterioration of the rotational performance.

The rear end of the spool shaft 15 is non-rotatably fixed to the slider 22. The intermediate gear 23 meshes with the pinion gear 12 via a reduction mechanism (not shown).

The rotor 3 has a cylindrical portion 3 as shown in FIG.
0, and first and second rotor arms 31 and 32 that are provided laterally of the cylindrical portion 30 so as to face each other. The cylindrical portion 30 and the rotor arms 31 and 32 are made of, for example, an aluminum alloy and are integrally formed. Cylindrical part 3

The bail arm 44 is swingable between the yarn guiding posture shown in FIG. 2 and the yarn releasing posture reversed from the yarn guiding posture.

Inside the cylindrical portion 30, inside the cylindrical portion 2c of the reel body 2a, a reverse rotation preventing mechanism 50 for constantly prohibiting reverse rotation of the rotor 3 is arranged. As shown in FIG. 4, the reverse rotation preventing mechanism 50 has a roller type one-way clutch 51 in which an inner ring 52 freely rotates. The one-way clutch 51 includes an inner ring 52 that is non-rotatably locked to the rotor 3 via the pinion gear 12, an outer ring 53 that is concentrically arranged on the outer peripheral side of the inner ring with a gap, and an inner ring 52.
And a plurality of rollers 54 arranged to be able to contact the outer ring 53
A spring member 58 for arranging the rollers 54 at equal intervals in the circumferential direction, and a spring holding member 55 for holding the spring member 58.
And have.

The inner ring 52 has an inner ring main body 56 rotatably mounted on the pinion gear 12 and in contact with the roller 54, and a connecting member 57 for connecting the inner ring main body 56 to the pinion gear 12 in a non-rotatable manner. . The inner ring main body 56 is a stepped tubular member having a large diameter portion 56a and a small diameter portion 56b. The large diameter portion 56a is formed with a locking recess 56c for locking the connecting member 57 so that it cannot rotate. The locking recess 56c is a substantially rectangular space when viewed from the front. Large diameter part 5
The outer peripheral surface of 6a is a precision-machined circular rolling surface 56d on which the roller 54 rolls. At the center of the small diameter portion 56b,
A circular mounting hole 56e is formed. Mounting hole 56e
Is attached to a portion of the pinion gear 12 where the chamfered portion 12b is not formed, and is attached to the pinion gear 12 in a centered state.

The connecting member 57 is a member having a substantially rectangular outer peripheral portion, and has an oval through hole 57a formed in the center thereof, which is non-rotatably locked to the chamfered portion 12b of the pinion gear 12. The outer peripheral portion of the connecting member 57 has a substantially rectangular shape and engages with the locking recess 56c of the inner ring main body 56 to lock the inner ring main body 56 in a non-rotatable manner. As a result, the inner ring main body 56 is non-rotatably connected to the pinion gear 12.

The outer ring 53 is non-rotatably mounted on the cylindrical portion 2c at the front of the reel body 2a, and its inner peripheral surface is slightly outwardly arranged to exert a wedge effect on the roller 54. A curved cam surface 53a is formed. The rollers 54 are cylindrical metal members, and are arranged at intervals in the circumferential direction so as to be in contact with the outer ring 53 and the inner ring body 56 of the inner ring 52.

The outer ring 53, the inner ring main body 56 of the inner ring 52, and the roller 54 are made of, for example, SUS4 which is a low corrosion-resistant metal material.
It is made of 40C. On the surface of these stainless steels, after forming a concentrated chromium oxide film with high corrosion resistance, a high-corrosion resistant film is formed by a surface modification treatment to stabilize the generated chromium oxide film. There is. The spring holding member 55 holds a spring member 58 that holds the roller 54 at intervals in the circumferential direction. Spring member 5
Numeral 8 urges the rollers 54 in the reverse rotation permitting direction at equal intervals to speed up the response to the reverse rotation permitting operation when the rotor 3 is rotated in the yarn winding direction from the state in which the rotor 3 is biased in the yarn feeding direction. It is provided for. The spring holding member 55 is made of, for example, a synthetic resin having high corrosion resistance such as nylon. The spring holding member 55 may also be made of SUS440C and covered with a highly corrosion resistant coating.

Here, the inner ring 52 is divided into an inner ring main body 56 that contacts the roller 54 and a connecting member 57.
Is rotatably mounted on the pinion gear 12. Then, the pinion gear 12 and the inner ring body 5 are connected by the connecting member 57 that is non-rotatably locked to the inner ring body 56 and the pinion gear 12.
Since 6 and 6 are connected, a highly accurate circular hole can be easily formed in the inner ring main body 56. Therefore, the inner ring main body 56 that comes into contact with the rollers 54 can be mounted on the pinion gear 12 with high accuracy, and rattling between the inner ring 52 of the one-way clutch 51 and the pinion gear 12 can be suppressed.

When the one-way clutch 51 including the inner ring 52, the outer ring 53 and the roller 54 is assembled to the pinion gear 12, the inner ring 52 is attached to the pinion gear 1.
It is rotatable with respect to 2. Therefore, when the outer ring 53 is non-rotatably mounted on the reel unit 2, after the outer ring 53 is mounted on the reel unit 2, the inner ring 52 is turned to rotate the pinion gear 1.
The phase in the direction of rotation with the connecting member 57 can be adjusted so as to be non-rotatable. Therefore, the work of incorporating the one-way clutch 51 into the pinion gear 12 becomes easy.

Further, since the inner ring main body 56, the outer ring 53 and the roller 54 of the one-way clutch 51 are made of metal coated with a high corrosion resistant coating, the corrosion resistance of these parts becomes high. Therefore, the corrosion resistance of the entire one-way clutch 51 is improved. Further, since the corrosion resistance is improved, it is not necessary to provide a seal member for preventing corrosion. For this reason,
It is possible to suppress deterioration of rotation performance.

In front of the one-way clutch 51,
A seal plate 59 with a lip for preventing the liquid from entering the reel body 2a is attached to the tubular portion 2c. The seal plate 59 is retained by a retaining spring 60 made of a wire that is bent into a pentagonal shape. As shown in FIG. 2, the spool 4 is arranged between the first rotor arm 31 and the second rotor arm 32 of the rotor 3. The spool 4 includes a spool body 7 rotatably mounted on a spool shaft 15 by two bearings 63 and 64,
It has a drag mechanism 8 for attaching the spool body 7 to the tip of the spool shaft 15.

The spool body 7 is a cylindrical member of large and small stages obtained by forging an aluminum alloy, for example, and has a cylindrical bobbin trunk 7a around which fishing line is wound.
It has front and rear large-diameter flange portions 7b and 7c provided on the front and rear of the bobbin trunk 7a, and a tubular skirt portion 7d extending rearward from the rear flange portion 7c. [Reel operation and operation] At the time of casting, the bail arm 44 is reversed to the line releasing posture. This makes the first
The bail support member 40 and the second bail support member 42 swing. In this state, cast the fishing rod while hooking the fishing line with the index finger of the hand holding the fishing rod. Then, the fishing line is released vigorously due to the weight of the tackle. When the handle 1 is rotated in the thread winding direction after the tackle has reached the water,
The rotor driving mechanism 5 causes the rotor 3 to rotate in the yarn winding direction. When the rotor 3 rotates, the bail arm 44 returns to the line winding position by a bail reversing mechanism (not shown), and the reverse rotation of the rotor 3 is prohibited, so that the discharge of the fishing line is stopped.

When winding the fishing line, the handle 1 is rotated in the line winding direction. Then, the rotation is transmitted to the rotor 3 via the face gear 11 and the pinion gear 12, and the rotor 3 rotates. When the rotor 3 rotates, the fishing line guided by the line roller 41 is wound around the spool 4. At this time, in the deep groove type spool 4 in which the diameter of the bobbin trunk portion 7a is smaller than that of the front and rear flange portions 7b and 7c, the diameter of the entire spool can be kept small and the amount of bobbin winding can be increased.

When fish is caught in the tackle, the rotor 3 tries to reverse in the line feeding direction. However, pinion gear 1
Since the reverse rotation prevention mechanism 50 prohibits the reverse rotation of the rotor 2, the rotor 3 non-rotatably connected to the pinion gear 12 does not rotate in the reverse direction. At this time, in the one-way clutch 51, the connecting member 57, which is non-rotatably connected to the rotor 3 via the pinion gear 12, tries to reverse in the yarn feeding direction. However, when the inner ring main body 56 locked to the connecting member 57 tries to reverse, the roller 54 bites into the cam surface formed on the outer ring 53, and the inner ring main body 56 is locked to the outer ring 53 which is non-rotatably locked to the reel body 2a. Is fixed and the inner ring main body 56 cannot be reversed. As a result, the reverse rotation of the rotor 3 is prohibited.

When fishing or cleaning the reel, the reel may get wet and liquid may infiltrate through the gap between the rear portion of the cylindrical portion 30 of the rotor 3 and the reel body 2. Even if liquid enters through this gap, the one-way clutch 51 uses the inner ring 52, the outer ring 53, and the roller 54 made of SUS440C having the highly corrosion-resistant coating formed thereon.
The one-way clutch 51 is less likely to corrode. Therefore, the one-way clutch 51 is unlikely to corrode even if the seal plate 59 is not used.

[Other Embodiments] (a) In the above embodiment, the one-way clutch 51 is always in the reverse rotation prohibited state, but it is possible to switch the one-way clutch between the reverse rotation enabled state and the reverse rotation prohibited state as in the conventional case. It may be configured. In this case, the spring holding member 55 is configured so that it can hold the roller 54 and can rotate by a predetermined angle. Then, the reel body 2 may be provided with, for example, a switching lever that can swing, and the switching lever may rotate the spring holding member 55 to switch the state of the one-way clutch 51.

Further, in addition to the rollers, only the outer ring or the inner ring on the rotating side may have high corrosion resistance. Further, the holding member may have corrosion resistance.

(D) In the above embodiment, the highly corrosion-resistant coating is formed, but the base material itself may be made highly corrosion-resistant without forming the highly corrosion-resistant coating. For example, the base material may be made of ceramic having high corrosion resistance such as alumina ceramic or SiC ceramic, stainless steel having high corrosion resistance such as SUS304, 316, 630, or metal having high corrosion resistance such as titanium or boron.
