DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a driving device,
The present invention relates to a spinning reel rotor driving device for transmitting rotation of a handle rotatably mounted on a reel body of a spinning reel to a rotor to rotate the rotor.

[0002]

2. Description of the Related Art In general, a spinning reel has a reel body mounted on a fishing rod and having a handle, 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. are doing. The reel body is provided with a rotor drive mechanism for rotating the rotor in conjunction with the rotation of the handle.
The rotor drive mechanism has a face gear that rotates in conjunction with the rotation of the handle, and a pinion gear that is non-rotatably mounted on the rotor and meshes with the face gear.

The face gear is a disc-shaped gear which is arranged concentrically with the rotation axis of the handle and has curved teeth which are curved and twisted on the outer peripheral end face. The pinion gear is rotatably mounted on the outer periphery of the spool shaft around the spool shaft, and is arranged so as to be offset from the rotation shaft of the handle in order to pass the spool shaft toward the oscillating mechanism arranged behind. I have. The pinion gear has a cylindrical helical tooth at the rear end that meshes with the curved teeth, and has a rotor mounting portion for mounting the rotor at the front end.

[0004]

In the conventional rotor drive mechanism, when the rotational force from the handle is transmitted from the face gear to the pinion gear, the curved and twisted teeth of the face gear are connected to the pinion gear. Since the teeth mesh with each other, the face gear is easily inclined to the rear side opposite to the meshing side at the meshing portion. In particular, if the torque transmitted by a large object increases, the face gear is likely to be greatly inclined. If the face gear is greatly inclined, the contact area at the meshing portion is reduced, the surface pressure is increased, and there is a possibility that the curved teeth or the helical teeth may be damaged. Further, the transmission efficiency of the rotational force is deteriorated, and the rotational force of the handle cannot be sufficiently transmitted to the rotor.

An object of the present invention is to suppress the inclination of a face gear in a rotor driving mechanism of a spinning reel.

[0006]

According to a first aspect of the present invention, there is provided a spinning reel rotor driving apparatus for transmitting rotation of a handle rotatably mounted on a reel body of a spinning reel to a rotor to rotate the rotor. A device,
A face gear, a pinion gear, and a gear receiving portion are provided. The face gear rotates in conjunction with the rotation of the handle. The pinion gear is a gear that is arranged along the front-rear direction that is different from the face gear and meshes with the face gear. The gear receiving portion is provided on the reel body so as to face at least the back surface of the meshing portion with the pinion gear on the back surface of the face gear, and is capable of contacting when the face gear transmits the driving force to the pinion gear and tilts. is there.

In this rotor drive device, when the face gear rotates together with the handle, the rotation is transmitted to pinion gears arranged along the staggered front-rear direction, and the rotor rotates around the front-rear axis in conjunction with the pinion gear. At this time, even if the face gear is inclined to the rear side around the meshing portion with the pinion gear, since the gear receiving portion is arranged on the rear side of the face gear, when the rear surface of the face gear contacts the gear receiving portion, The face gear does not lean any further. For this reason, the inclination of the face gear can be suppressed.

According to a second aspect of the present invention, there is provided a spinning reel rotor driving apparatus according to the first aspect, wherein the gear receiving portion is provided with a gap on the back surface of the engaging portion so that the gear receiving portion does not contact when the face gear is not inclined. It is provided in. In this case, when a large rotational force is not transmitted, the gear receiving portion does not contact the rear surface of the face gear, so that the rotational resistance does not increase and the decrease in rotational efficiency can be suppressed.

According to a third aspect of the present invention, there is provided a spinning reel rotor driving apparatus according to the first or second aspect, wherein the gear receiving portion is arranged so as to face a rear surface of the meshing portion of the face gear and extend along a radial direction of the face gear. The roller is rotatably mounted on the reel body. In this case, the inclination can be suppressed efficiently only by supporting the back surface of the meshing portion of the face gear with the largest amount of inclination by the roller, so that the configuration of the gear receiving portion is simplified.

According to a fourth aspect of the present invention, there is provided a spinning reel rotor driving apparatus according to the third aspect, wherein the roller is a rolling bearing rotatably mounted around an axis. In this case, by using a rolling bearing having a small rotational resistance for the roller, even if the face gear is inclined and comes into contact with the gear receiving portion, it is possible to suppress a decrease in rotational efficiency due to an increase in the rotational resistance.

The bail arm 44 is swingable between a yarn guiding posture shown in FIG. 3 and a yarn releasing posture reversed from the yarn guiding posture.

A cover 45 is mounted on the outer peripheral side of the first bail support member 40, and the bail arm 44 is returned from the line releasing position to the line guiding position inside the cover 45 in conjunction with the rotation of the rotor 3. In addition, a bail reversing mechanism 46 for maintaining the state in both postures is arranged.

[Reel Operation and Operation] At the time of casting, the bail arm 44 is reversed to the line releasing posture.
Thereby, the first bail support member 40 and the second bale support member 42 swing. In this state, the fishing rod is cast while catching the fishing line with the index finger of the hand holding the fishing rod. Then, the fishing line is released vigorously by the weight of the device. When the handle 1 is rotated in the line winding direction in this state, the rotor 3 is rotated in the line winding direction by the rotor driving mechanism 5, the bail arm 44 is returned to the line winding position by the bail reversing mechanism 46, and the fishing line is wound around the spool 4. Will be possible.

When the fish is raised on the device, the handle 1 is rotated in the line winding direction. Handle 1
Is rotated in the line winding direction, the face gear 11 rotates together with the handle shaft 10, the rotor 3 rotates in the line winding direction via the pinion gear 12 meshing with the face gear 11, and the fishing line is wound around the spool 4. When a large tension acts on the fishing line when a large object is applied to the device, a large rotational force acts on the pinion gear 12 via the rotor 3. When a large rotational force acts on the pinion gear 12, the face gear 11 tends to tilt in a direction away from the pinion gear 12 at a portion where the pinion gear 12 meshes.

However, since the gear receiving portion 9 is arranged on the back side of the face gear 11 with a slight gap therebetween, if the face gear 11 is slightly inclined and comes into contact with the gear receiving portion 9, the face gear 11 is further extended. Will not tilt. In addition, even if the face gear 11 contacts the gear receiving portion 9, the contact portion of the gear receiving portion 9 is a roller 9b composed of a ball bearing rotatably supported on the reel body 2a around a radial axis of the face gear 11. Therefore, the gear receiving portion 9 rotates together with the face gear 11. For this reason, even if the face gear 11 is slightly inclined and comes into contact with the gear receiving portion 9, the rotation of the handle 1 is not so heavy, and a decrease in rotation efficiency due to an increase in rotation resistance can be suppressed.

Further, since the rear side of the face gear 11 can be supported by the gear receiving portion 9, the face gear 11
The overall rigidity and strength can be maintained high without increasing the rigidity of the rotor itself more than necessary, and the weight of the rotor drive mechanism 5 can be reduced as a whole. [Other Embodiments] (a) In the above embodiment, the roller is constituted by the ball bearing itself, but the present invention is not limited to this. For example, a bearing such as a ball bearing or a slide bearing may be arranged in the roller, or the roller may be configured by a slide bearing having a self-lubricating function or a slide bearing made of gunmetal. Further, a contact member having good slippage instead of a roller may be arranged with a gap so as to come into contact when the face gear is inclined.

(B) In the above embodiment, the roller 9b is arranged with a gap from the back side of the face gear 11,
They may be arranged in contact with each other. (C) In the above-described embodiment, the gear receiving portion including the roller is disposed on the back side of the meshing portion.
And a ring member arranged concentrically with the entire surface of the rear side of the curved teeth 11a of the face gear 11 so that the ring member is rotatably and axially immovable on the reel body 2a via, for example, a thrust bearing. It may be arranged.

(D) In the above embodiment, the rotating shaft of the roller 9b is arranged along the radial direction of the face gear 11, but if it is small, it is offset from the radial direction or inclined with respect to the radial direction. You may. By arranging the rotating shaft slightly shifted from the radial direction in this way, the degree of freedom in designing and arranging the roller 9b is increased.

[0033]

According to the present invention, even if the face gear is inclined to the rear side around the meshing portion with the pinion gear, the gear receiving portion is arranged on the rear side of the face gear, so When the back surface of the face gear comes into contact, the face gear does not tilt any further. For this reason, the inclination of the face gear can be suppressed.
