DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a meshing adjustment structure, and more particularly to a meshing mechanism for adjusting meshing between a face gear provided on a handle shaft rotatably supported by a bearing on a reel body of a spinning reel and a pinion gear meshing with the face gear. For the structure.

[0002]

2. Description of the Related Art In general, a spinning reel has a reel body, a rotor rotatably supported by the reel body, and a spool provided in front of the rotor and around which the fishing line is wound. The rotor rotates integrally with a pinion gear provided on the outer peripheral side of the spool shaft. The spool is
It reciprocates back and forth by a level wind mechanism driven by an intermediate gear meshing with the pinion gear. This pinion gear meshes with a face gear (master gear) provided on a rotation shaft (handle shaft) of the handle orthogonal to the pinion gear, and rotates by rotation of the handle.

In order to adjust the meshing between the face gear and the pinion gear to an optimum state, it is desirable to pressurize the face gear in the meshing direction. When the face gear is pressurized in this way, backlash with the pinion gear is reduced, backlash is suppressed, and rotation is smooth. Conventionally, in order to pressurize the face gear in the meshing direction, a metal spring washer or a coil spring is provided in a gap between the face gear and a bearing disposed close to the back surface (the surface opposite to the meshing position) of the face gear. Are arranged in a compressed state.

[0004]

In the above-mentioned conventional configuration,
If the backlash is suppressed by reducing the play between the face gear and the pinion gear by a large applied pressure, the rotation of the steering wheel becomes heavy. Therefore, in order to keep the rotation of the steering wheel light, it is necessary to apply a small pressure to the face gear. However, since the gap between the bearing and the face gear is small, if a metal spring washer or coil spring is used, the applied pressure changes greatly due to a slight change in the gap caused by the axial movement of the handle shaft, etc. It is difficult to keep the pressure small. Therefore, in order to reduce the backlash in consideration of the fluctuation of the gap and to adjust the meshing to an optimal state, the rotation of the steering wheel must actually be heavy. Conversely, if the rotation of the handle is reduced, it is difficult to pressurize the face gear, causing backlash, and the rotation of the handle is not smooth.

An object of the present invention is to make it possible to maintain the rotation of the handle lightly and smoothly.

[0006]

According to a first aspect of the present invention, there is provided a spinning reel face gear meshing adjustment structure, comprising a face gear provided on a handle shaft rotatably supported by a bearing on a reel body of the spinning reel, and a pinion meshing therewith. This is a structure for adjusting meshing with a gear, and includes a sliding washer and a ring member made of an elastic resin. The sliding washer is arranged between the bearing and the face gear. The ring member is arranged between the sliding washer and the face gear so as to contact both.

In this meshing adjustment structure, the ring member is disposed between the sliding washer and the face gear disposed in contact with the bearing so as to contact both. Here, even if the gap between the two members fluctuates, the pressure applied by the ring member does not fluctuate much compared to a metal spring because the ring member is made of an elastic resin. Therefore, the rotation of the handle can be maintained in a light state. In addition, since the face gear can always be pressurized by the ring member, the backlash is reduced, and the rotation of the steering wheel can be maintained in a smooth state.

According to a second aspect of the present invention, there is provided a spinning reel face gear meshing adjustment structure according to the first aspect.
The bearing is a rolling bearing, and the sliding washer is arranged in contact with the inner ring of the rolling bearing. In this case, since the slide washer contacts only the inner ring of the rolling bearing, the rotation of the handle can be kept lighter than when the sliding member contacts the outer ring and the inner ring.

According to a third aspect of the present invention, in the structure for adjusting the meshing of the face gear of the spinning reel according to the first or second aspect, the ring member is an O-ring. In this case, by using an inexpensive and easily obtainable O-ring, a light and smooth meshing adjustment structure can be realized at low cost and easily. According to a fourth aspect of the present invention, there is provided a spinning reel face gear meshing adjustment structure according to any one of the first to third aspects.
A ring-shaped recess is formed in the face gear outside the handle shaft, and the ring member is mounted in the recess. In this case, since the ring member is mounted in the concave portion, the ring member does not compress to a depth greater than the depth of the concave portion even when a large load is applied, and an increase in applied pressure can be suppressed.

According to a fifth aspect of the present invention, a meshing adjustment structure for a face gear of a spinning reel adjusts meshing between a face gear provided on a handle shaft rotatably supported by a bearing on a reel body of the spinning reel and a pinion gear meshing with the face gear. And a sliding washer and a ring member made of an elastic resin. The sliding washer is arranged between the bearing and the face gear. The ring member is disposed between the reel body and the side face of the bearing opposite to the face gear so as to contact both faces.

In this case, since the ring member is disposed between the bearing and the reel body, the gap between the bearing and the face gear can be kept small. In addition, since it is not necessary to provide a storage space for the ring member in the face gear,
The thickness of the face gear is not reduced, and the strength of the face gear can be maintained high. In addition, even if the gap between the bearing and the face gear changes, the applied pressure by the ring member does not fluctuate much compared to a metal spring because the ring member is made of an elastic resin. Therefore, the rotation of the handle can be maintained in a light state. In addition, since the face gear can always be pressurized by the ring member, the backlash is reduced, and the rotation of the steering wheel can be maintained in a smooth state.

a and a flange portion 4c fixed to the front end.
The spool shaft 8 is movable in the front-rear direction by the level wind mechanism 7.

The rotor drive mechanism 5 includes a handle shaft 10 having the handle 1 fixed at the tip, a master gear 11 using a face gear that rotates integrally with the handle shaft 10, and a pinion gear 12 meshing with the master gear 11. Have. As shown in FIG. 2, the handle shaft 10 is disposed in the left-right direction of the body 2a of the reel body 2, and includes bearings 13a, 13 made of shielded ball bearings.
It is rotatably supported by b. A master gear 11 is formed integrally with the handle shaft 10. A shaft 14 having a square cross section extending from the handle 1 is non-rotatably inserted into the center of the handle shaft 10. This shaft 14
Is fixed by a set screw 16 extending from a cap 15 attached to the side surface of the body 2a. With this configuration, the handle 1 becomes detachable and can be arranged on either the left or right side of the reel body 2.

The master gear 11, as shown in FIG.
It is a substantially disk-shaped member integrally formed with the handle shaft 10, and has a tooth portion 11 a that meshes with the pinion gear 12 on the peripheral end face on the pinion gear 12 side. A ring-shaped recess 11b is formed on the side surface of the master gear 11 on the bearing 13a side at the boundary with the handle shaft 10. A ring member 18 made of an elastic resin for pressurizing the master gear 11 toward the pinion gear 12 (engagement direction) is mounted in the ring-shaped recess 11b. The ring member 18 is, for example, an exercise (P-type) made of nitrile rubber.
O-ring. A slide washer 19 is arranged between the ring member 18 and the bearing 13a. The sliding washer 19 is a metal ring-shaped member, and contacts only the inner ring 17a of the bearing 13a and does not contact the outer ring 17b. The wire diameter of the ring member 18 is slightly larger than the gap from the bottom of the recess 11b to the slide washer 19, and the ring member 18 is mounted in a slightly compressed state.

As described above, the ring member 18 made of an elastic resin is used.
Is arranged in a compressed state between the slide washer 19 and the master gear 11 to pressurize the master gear 11,
Even if the gap between the master gear 11 and the slide washer 19 fluctuates, the pressure applied by the ring member 18 does not fluctuate much as compared with a metal spring. Therefore, the rotation of the handle 2 can be maintained in a light state. In addition, since the master gear 19 can always be pressurized with a small force by the ring member 18, the backlash is reduced, and the rotation of the handle 2 can be maintained in a smooth state. Also, a ring member 1 made of an elastic resin
Since the master gear 8 is used, even if the master gear 11 vibrates due to the rotation of the handle 1, it is absorbed by the ring member 18 and the operation feeling of the handle 1 does not deteriorate due to the vibration.

The pinion gear 12 is formed in a cylindrical shape, and is arranged below the handle shaft 10 along the front-rear direction orthogonal to the handle shaft 10, as shown in FIG. The front portion 12a of the pinion gear 12 extends through the center of the rotor 3 toward the spool 4. The rotor braking mechanism 6 has a braking unit 20 and a braking holding unit 21 for holding the braking unit 20 in a braking state. The brake holding unit 21 has a swing lever 22 that is swingably supported by the body 2a. The swing lever 22 can switch a later-described braking lever 30 between a braking position and a braking release position, and can hold the braking lever 30 at the braking position.

The brake unit 20 includes a brake lever 30 swingably supported by the body 2 a, a brake unit main body 31 that is braked by the brake lever 30, and a brake unit main body 31 that rotates the rotor 3 in the line feeding direction. And a one-way clutch 32 that rotates only in conjunction therewith. The braking lever 30
At the boundary between the body 2a and the mounting portion 2b, the body 2a is swingably supported by the support shaft 33, and is urged counterclockwise in FIG. 1 by an urging member (not shown). The braking lever 30 has an operation lever portion 30a that curves from the support shaft 33 and extends obliquely upward. A braking action portion 30b is provided at a distal end that curves from the support shaft 33 and extends obliquely downward. . The tip of the operation lever portion 30a is arranged near the mounting portion 2c.

As shown in FIG. 4, the braking section main body 31 supports a braking cylinder 40 disposed concentrically with the rotor 3 on the inner peripheral side of the rotor 3 and the braking cylinder 40 swingably and non-rotatably. A rotating cylinder 41 and a braking shoe 42 attached to the body 2a. The braking cylinder 40 has a bottomed cylindrical shape, and the tip of the outer peripheral surface 40 a is disposed between the braking shoe 42 and the braking action portion 30 b of the braking lever 30.
The braking cylinder 40 has a support surface 40c that is bent inward at the center. The support surface 40c has a cylindrical shape. A cross-shaped engaging groove 4 is formed on the bottom surface 40b of the braking cylinder 40.
3 are formed. The engagement groove 43 extends to an end of the support surface 40c.

The rotating cylinder 41 has a front end which is integrally rotated by the one-way clutch 32 with respect to the rotation of the rotor 3 in the line reeling-out direction, and is supported so that the rotating force of the rotor 3 does not act upon winding. The body 2a is rotatably supported by the body 2a. A universal joint 45 for supporting the support surface 40c is provided on the outer periphery of the intermediate portion of the rotary cylinder 41. The universal joint 45 is screwed into the rotating cylinder 41 and formed into a rotating ring 45a having a part of a spherical surface formed on an outer peripheral surface thereof, and four columnar cylindrical shapes projecting outwardly in a cross shape from the peripheral surface of the rotating ring 45a. And an engaging projection 45b. Since the engagement protrusion 45b is engaged with the engagement groove 43 and the support surface 40c is supported by the rotating ring 45a, the braking cylinder 40 is supported by the rotating cylinder 41 so as to be non-rotatable and swingable.

A pair of spring receiving rings 46 are arranged on both sides of the rotating ring portion 45a in contact with each other. Between the right-side spring receiving ring 46 and the bearing 44 and between the left-side spring receiving ring 46 and the one-way clutch 32, the tip of the braking cylinder 40 is connected to the braking shoe 42 and the braking action portion 30b of the braking lever 30. A conical coil spring 47 for maintaining a predetermined posture without contact is arranged in a compressed state.

As described above, since the braking cylinder 40 is non-rotatably and swingably supported by the rotating cylinder 41, when the braking is performed by the braking lever 30, the braking cylinder 40 is positioned at a position indicated by a two-dot chain line in FIG. Lean on. However, the braking cylinder 40
Are pivotally supported by the rotating cylinder 41, so that no bending moment acts on the rotating cylinder 41 and the pinion gear 12 during braking, so that these are not easily deformed, and the rotation of the rotor 3 is not affected and the rotation is hardly heavy.

The one-way clutch 32 is of an outer ring idle type, in which the outer ring is fixed to the cylindrical portion of the rotor 3 and the inner ring is fixed to the outer periphery of the tip of the rotating cylinder 41. This one-way clutch 32 transmits its rotational force to the rotating cylinder 41 only when the rotor 3 rotates in the line pay-out direction. Therefore, when the rotor 3 rotates in the line feeding direction, the rotating cylinder 41 rotates and braking by the braking mechanism 6 becomes possible.
On the other hand, when the rotor 3 rotates in the yarn winding direction, the rotating cylinder 4
1 does not rotate and cannot be braked by the rotor brake mechanism 6.

As shown in FIGS. 1 and 2, the level wind mechanism 7 is a mechanism for moving the spool shaft 8 fixed to the center of the spool 4 in the front-rear direction to move the spool 4 in the same direction. is there. The level wind mechanism 7 includes a screw shaft 51 disposed below the spool shaft 8, a slider 52 that moves in the front-rear direction along the screw shaft 51, and a screw shaft 51.
And an intermediate gear 53 fixed to the front end of the motor. The screw shaft 51 is arranged in parallel with the spool shaft 8, and is rotatably supported by the body 2a. A spiral groove 51a is formed on the outer periphery of the screw shaft 51. The rear end of the spool shaft 8 is fixed to the slider 52. The intermediate gear 53 is engaged with the pinion gear 12.

[Reel Operation and Operation] At the time of casting, the bail 9 is tilted to the line releasing position side and the fishing rod is swung out, so that the fishing line wound around the outer periphery of the spool 4 is paid out. When winding the fishing line, the bail 9 is returned to the line winding posture. When the handle 1 is rotated in this state,
This rotational force is transmitted to the pinion gear 12 via the handle shaft 10 and the master gear 11. This master gear 1
When the rotational force is transmitted from the first gear 1 to the pinion gear 12, the master gear 11 is pressurized toward the pinion gear 12, so that even if the gap between the master gear 11 and the slide washer 19 fluctuates, the ring member The applied pressure by 18 does not fluctuate much compared to a metal spring. Therefore, the rotation of the handle 2 can be maintained in a light state. Moreover, the ring member 18
As a result, the master gear 19 can always be pressurized with a small force, so that backlash is reduced and the rotation of the handle 2 can be maintained in a smooth state.

The torque transmitted to the pinion gear 12 is
The power is transmitted to the rotor 3 via the front portion 12a of the pinion gear 12. At this time, since the rotor 3 rotates in the yarn winding direction, this rotational force is not transmitted to the rotating cylinder 41 by the one-way clutch 32 as described above. When the pinion gear 12 rotates, the rotation is transmitted to the level wind mechanism 7 by the intermediate gear 53, and the spool shaft 8 reciprocates in the front-rear direction.

To exchange the fish with the rotor 3 by rotating the rotor 3 in the reverse direction, the swing lever 22 is swung to the left by 45 degrees to bring the brake to the release state. Then, the brake lever 30 is returned to the brake release position by the urging member (not shown). In this state, the brake lever 30 is operated to exchange with the fish. When the fishing line is pulled by the fish and the rotor 3 rotates in reverse, as described above, the rotational force is transmitted to the rotating cylinder 41 via the one-way clutch 32, and further transmitted to the braking cylinder 40 via the universal joint 45. The braking cylinder 40 rotates integrally with the rotor 3. Then, the brake lever 30 is moved in the direction indicated by the arrow A in FIG.
Swinging in the opposite direction to the braking cylinder 30
The inner periphery of the leading end of the outer peripheral surface 40a is pressed to tilt the braking cylinder 40 to the position shown by the two-dot chain line in FIG. As a result, a braking force acts on the rotor 3 that rotates in the reverse direction.

The amount of reverse rotation of the rotor 3 can be arbitrarily adjusted by adjusting the braking force by adjusting the force applied to the braking lever 30. Also, at this time, the braking cylinder 40 is
Is supported by the universal joint portion 45 so as to be able to swing freely, so that no force is exerted on the pinion gear 12 so as to reduce it, and the rotation of the rotor 3 does not become heavy. Also, since the outer ring idle-type one-way clutch 32 is used,
Even if the rotation of the rotor 3 is reversed to rotate at a high speed, the higher the rotation speed, the more stable the operation at the start of braking.

When moving the fishing spot or storing the reels, the swing lever 22 is swung from 45 degrees left to 45 degrees right to swing the brake lever 30 to the braking position. [Other Embodiments] (a) As shown in FIG. 5, a ring-shaped recess 11b may be formed slightly outside the handle shaft 10, and a ring member 18 may be mounted therein. Here, as shown in FIG.
A recess 11b is formed with a step 11c radially outward from the handle shaft 10 at a distance h (for example, 0.2 mm). The distance d between the end face of the step 11c and the slide washer 19
1 is, for example, 0.2 mm, and the distance d2 between the end face of the master gear 11 outside the recess 11b and the slide washer 19 is, for example, 0.4 mm. When the recess 11b and the step are formed in this way and the ring member 18 is mounted thereon, even if the master gear 11 moves to the bearing side when a large load is applied, the end face of the step 11c is fixed to the inner ring 17 of the bearing 13a.
a, and can receive the load.

(B) As shown in FIG. 7, a ring member 18a may be mounted between the reel body 2a and the bearing 13c. Here, a sliding bearing such as a metal or resin bush is used for the bearings 13c and 13d instead of a rolling bearing such as a ball bearing. An O-ring having a rectangular cross section is used as the ring member 18a. Two sliding washers 1 are provided between the bearing 13c and the master gear 11.
9a is mounted.

In such a configuration, since it is not necessary to form the concave portion 11b in the master gear 11, the thickness of the master gear 11 can be maintained without being reduced in thickness. Further, the ring member 18a is connected to the reel body 2a and the bearing 13c.
Between the ring member 18a and the bearing 13c.
No slippage occurs between When such a slide bearing is employed, the reel body 2a which does not rotate and the bearing 13c
It is preferable to mount the ring member 18a between the two.

(C) The ring member 18b may be made of an elastic resin having a home base shape in cross section as shown in FIG. Ring member 1 having such a cross-sectional shape
In the case of 8b, the range of the weak urging force when compressed and deformed is widened, and a small applied pressure can be obtained over a wider range. (D) The material of the ring member is not limited to nitrile rubber, but may be another elastic resin such as urethane rubber.

[0035]

According to the present invention, even if the gap between the sliding washer and the face gear fluctuates, since the ring member is made of an elastic resin, the pressure applied by the ring member is smaller than that of a metal spring. Does not fluctuate much. Therefore, the rotation of the handle can be maintained in a light state. In addition, since the face gear can always be pressurized by the ring member, the backlash is reduced, and the rotation of the steering wheel can be maintained in a smooth state.
