Technical Field

The present invention relates to a fishing reel, and more particularly to a fishing reel having a bearing for supporting a spool shaft and a planetary gear rotatable about the spool shaft.

Background

Conventionally, for example, the following fishing reels are known: the reel has a lever drag mechanism disposed around the axis of the reel shaft to brake the rotation of the reel in the wire feeding direction. A part of the lever drag mechanism is disposed inside a cover member that covers the handle side of the reel body. The cover member has a cylindrical flange portion, and a bearing for rotatably supporting the planetary gear is disposed inside the flange portion.

Patent document 1: japanese patent application laid-open No. 2010-099047.

In a conventional fishing reel, when seawater enters the reel body, the seawater adheres to a bearing that supports a planetary gear, and the bearing may corrode or the rotational performance of the bearing may be reduced. In addition, the lubricating oil applied to the interior of the reel unit may intrude into the bearing and the rotation performance may be impaired. Therefore, it is considered to dispose the seal member or the like adjacently to the bearing, but the irregularities of the tooth portion of the planetary gear prevent waterproofing, and a sufficient effect cannot be obtained.

Disclosure of Invention

The invention aims to provide a fishing reel capable of inhibiting sea water from being attached to a bearing for supporting a planetary gear and preventing lubricating oil from entering the bearing for supporting the planetary gear.

A fishing reel according to one aspect of the present invention includes a reel body, a spool shaft, a planetary gear, a sleeve member, a bearing, and a seal member. The reel body has a bearing housing portion. The spool shaft is rotatably supported by the reel body. The planetary gear is rotatable about the spool shaft axis. The planetary gear includes a gear body and a tooth portion formed on an outer peripheral surface of an intermediate portion of the gear body. The sleeve member is cylindrical and is fitted to the outer peripheral surface of the planetary gear. The sleeve member has a large diameter portion arranged axially adjacent to the tooth portion of the planetary gear, and a small diameter portion having a diameter smaller than the outer diameter of the large diameter portion. The bearing is disposed in a bearing housing portion of the reel body, and rotatably supports the planetary gear via a sleeve member. The bearing has an inner ring that contacts the outer peripheral surface of the small-diameter portion of the sleeve member. The seal member is annular and is disposed in contact with the inner peripheral surface of the bearing housing portion of the reel unit and the outer peripheral surface of the large diameter portion of the sleeve member.

In this fishing reel, the seal member is disposed in contact with the large-diameter portion of the sleeve member disposed adjacent to the tooth portion of the planetary gear, so that it is possible to effectively suppress the adhesion of seawater to the bearing when seawater enters the interior of the reel body by means of the seal member. Further, the lubricating oil applied to the reel body can be effectively inhibited from infiltrating into the interior of the bearing by the seal member. Further, since the planet gear is supported by the bearing via the sleeve member, the planet gear can be supported by the bearing with high accuracy.

Preferably, the outer diameter of the large diameter portion of the sleeve member is larger than the diameter of the tooth bottom of the tooth portion of the planetary gear. In this case, when seawater or lubricating oil is transmitted to the tooth portion of the planetary gear, the large diameter portion and the seal member can further effectively suppress adhesion of seawater to the bearing.

Preferably, the planetary gear has a fitting portion formed in the gear body to fit the sleeve member, and an outer diameter of the fitting portion is smaller than an outer diameter of a gear portion of the planetary gear. In this case, when the sleeve member is fitted to the fitting portion of the planetary gear, the axial movement of the sleeve member can be restricted by the end face of the tooth portion of the planetary gear.

Preferably, the seal member has a lip portion with a thickness that becomes thinner as approaching the large diameter portion of the collar member. In this case, since the contact area of the seal member with the sleeve member is reduced, the reduction in the rotation performance of the sleeve member can be suppressed.

Effects of the invention

According to the present invention, it is possible to provide a fishing reel in which adhesion of seawater to a bearing that supports a planetary gear and intrusion of lubricating oil into the bearing that supports the planetary gear can be suppressed.

Detailed Description

Fig. 1 is a perspective view of a dual-bearing reel (an example of a fishing reel) 100 according to an embodiment of the present invention. Fig. 2 is a cross-sectional view of the dual-bearing reel 100. The dual-bearing reel 100 includes a reel unit 2, a spool shaft 3, a spool 4, a handle 5, a rotation transmission mechanism 6, a lever drag mechanism 7, a sleeve member 8, a bearing 9, and a seal member 10.

In the following description, the fishing line is released in the forward direction and the reverse direction is referred to as the backward direction. The left and right sides refer to the left and right sides when the dual-bearing reel 100 is viewed from the rear. The direction in which the spool shaft 3 extends is referred to as the "axial direction", the direction perpendicular to the spool shaft 3 is referred to as the "radial direction", and the direction around the axis of the spool shaft 3 is referred to as the "circumferential direction".

The reel unit 2 includes a frame 11, a right cover 12 covering the right side of the frame 11, and a left cover 13 covering the left side of the frame 11. The frame 11 includes a 1 st side plate 11a, a 2 nd side plate 11b arranged at an interval in the axial direction from the 1 st side plate 11a, and a plurality of coupling portions 11c coupling the 1 st side plate 11a and the 2 nd side plate 11 b. The 1 st side plate 11a and the 2 nd side plate 11b are formed in a disc shape and have openings through which the roll 4 can pass. The 2 nd side plate 11b is formed integrally with the left side cover 13, but may be separate from the left side cover 13.

The right cover 12 has a bulging portion 15, a brim portion 16, and a brim portion 17. The bulging portion 15 is formed to bulge radially and axially from the 1 st side plate 11 a. The bulging portion 15 is formed to bulge forward and downward from the 1 st side plate 11 a.

The collar portion 16 is cylindrical and protrudes axially outward from the bulging portion 15. The collar 17 is cylindrical and protrudes axially outward from the bulging portion 15 below the collar 16.

Fig. 3 is an enlarged sectional view of the periphery of the brim portion 16. The flange portion 16 has a bearing housing portion 16a in which the bearing 9 is disposed. The bearing housing portion 16a has a support portion 16b that contacts the outer ring 9a of the bearing 9. The bearing 9 is restricted from moving axially outward by the support portion 16 b. Further, a fitting groove 16c for fitting the seal member 10 is formed in the inner peripheral surface of the bearing housing portion 16 a.

The spool shaft 3 is supported by the reel unit 2 so as to be axially movable and non-rotatable. The spool shaft 3 is disposed on the reel unit 2 so as to axially penetrate the spool 4 and the flange portion 16.

The spool 4 is rotatably supported by the spool shaft 3 via bearings 18a and 18b disposed on the outer periphery of the spool shaft 3. The bearings 18a and 18b are restricted from moving in the axial direction by the urging members 19a and 19b fitted around the axis of the spool shaft 3 and the spool 4. The spool shaft 3 and the spool 4 are integrally movable in the axial direction together with the bearings 18a and 18 b.

The handle 5 is rotatably fitted to the side of the reel body 2. In the present embodiment, the handle 5 is rotatably attached to the right side cover 12 of the reel unit 2. The handle 5 is prevented from rotating in the wire unwinding direction by the one-way clutch 20 disposed inside the flange portion 17. When the handle 5 is disposed on the left side of the reel unit 2, a bulging portion 15 is formed in the left cover 13.

The rotation transmission mechanism 6 transmits the rotation of the handle 5 to the drum 4. The rotation transmitting mechanism 6 has a well-known shift operating mechanism 22. The shift operation mechanism 22 mainly includes a master gear 23 for high-speed winding, a 2 nd master gear 24 for low-speed winding, planetary gears 25 meshing with the master gear 23, a 2 nd planetary gear 26 meshing with the 2 nd master gear 24, engagement pieces 27, an operation shaft 28, and urging members 29a and 29 b. Fig. 2 shows a state in which the engaging piece 27 engages with the main gear 23. The shift operating mechanism 22 has the same structure as the conventional one, and therefore, a detailed description thereof is omitted.

The planetary gear 25 is rotatable about the axis of the spool shaft 3. As shown in fig. 3, the planetary gear 25 includes a gear main body 25a, a tooth portion 25b, and a fitting portion 25 c.

The gear main body 25a is cylindrical and extends in the axial direction. The spool shaft 3 axially penetrates the inside of the gear body 25 a. The tooth portion 25b is formed on the outer peripheral surface of the intermediate portion of the gear main body 25a, and meshes with the master gear 23. The fitting portion 25c is cylindrically formed at one end of the gear main body 25 a. In the present embodiment, the fitting portion 25c is formed at the right end of the gear main body 25a, and the sleeve member 8 is fitted to the fitting portion 25 c. The outer diameter of the fitting portion 25c is preferably smaller than the outer diameter of the tooth tip 25d of the tooth portion 25 b. Thereby, the movement of the sleeve member 8 in the direction approaching the spool 4 can be regulated by the tooth portion 25 b.

The lever drag mechanism 7 brakes the rotation of the reel 4 in the wire unwinding direction. The structure of the lever drag mechanism 7 is the same as that of the conventional one and will be briefly described. The rod drag mechanism 7 has a friction disk 31, a drag disk 32, and a moving mechanism 33. The friction disk 31 is disc-shaped and fixed to the outer surface of the flange of the spool 4.

The drag disk 32 is integrally rotatably coupled to the planetary gear 25. The drag disk 32 is rotatably supported on the spool shaft 3 by a bearing 34 attached to the spool shaft 3. The drag disk 32 is prevented from rotating in the thread unwinding direction by a reverse rotation preventing mechanism, not shown, disposed inside the right cover 12. The drag disk 32 has a brake disk 32a arranged axially opposite to the friction disk 31.

The moving mechanism 33 is a mechanism for moving the spool shaft 3 in the axial direction in response to an operation of a drag lever 43a disposed swingably on the outer peripheral portion of the collar portion 16. When the drag lever 43a is operated, the spool shaft 3 moves in the axial direction together with the spool 4 in accordance with the swing of the drag lever 43 a. As the spool 4 moves, the friction plate 31 moves in the axial direction, and the friction force between the brake disk 32a of the drag plate 32 and the friction plate 31 changes. Thereby, the braking force acting on the spool 4 is adjusted. Fig. 2 shows a state in which the brake disk 32a of the drag disk 32 and the friction disk 31 do not contact each other, that is, a state in which the rotation of the spool 4 is not braked by the lever drag mechanism 7.

The sleeve member 8 is cylindrical and is fitted to the outer peripheral surface of the planetary gear 25. In the present embodiment, the sleeve member 8 is attached to the attachment portion 25c of the planetary gear 25. The sleeve member 8 is fitted to the fitting portion 25c of the planetary gear 25 and rotates integrally with the planetary gear 25. As shown in fig. 3, the collar member 8 has a large diameter portion 8a, a small diameter portion 8b, and a stepped portion 8 c.

The large diameter portion 8a is annular and is disposed axially adjacent to the tooth portion 25b of the planetary gear 25. In the present embodiment, the large diameter portion 8a is in contact with the tooth portion 25b of the planetary gear 25 in the axial direction. The large diameter portion 8a is disposed between the tooth portion 25b of the planetary gear 25 and the inner ring 9b of the bearing 9. The outer diameter of the large-diameter portion 8a is smaller than the inner diameter of the outer ring 9a of the bearing 9. Preferably, the outer diameter of the large diameter portion 8a is larger than the diameter of the bottom 25e of the tooth portion 25b of the planetary gear 25. More preferably, the outer diameter of the large diameter portion 8a is larger than the outer diameter of the tooth tip 25d of the tooth portion 25b of the planetary gear 25. This can suppress the seawater from flowing toward the bearing 9 through the large diameter portion 8a when the seawater reaches the tooth portion 25b of the planetary gear 25.

The small diameter portion 8b is annular and has a diameter smaller than the outer diameter of the large diameter portion 8 a. The step portion 8c extends in the radial direction between the large diameter portion 8a and the small diameter portion 8 b.

The bearing 9 is disposed inside the bearing housing portion 16a, and rotatably supports the planetary gear 25 via the sleeve member 8. The bearing 9 is fixed to the inside of the bearing housing portion 16a by press-fitting, for example. The inner race 9b of the bearing 9 is disposed in contact with the outer peripheral surface of the small diameter portion 8b of the sleeve member 8. That is, the small diameter portion 8b of the sleeve member 8 is fitted to the inner ring 9b of the bearing 9 and rotates integrally with the inner ring 9 b. The inner ring 9b is in contact with the step portion 8c of the sleeve member 8.

The seal member 10 is a member made of, for example, rubber, which is elastically deformable. The seal member 10 seals between the inner peripheral surface of the bearing housing portion 16a and the outer peripheral surface of the large diameter portion 8a of the collar member 8. Specifically, the seal member 10 is annular and is disposed in contact with the inner peripheral surface of the bearing housing portion 16a and the outer peripheral surface of the large diameter portion 8a of the sleeve member 8. The seal member 10 is disposed so that the bottom portion thereof contacts the end surface of the outer ring 9a of the bearing 9. The seal member 10 is detachably attached to the attachment groove 16c of the bearing housing portion 16 a.

The seal member 10 preferably has a lip 10a with a thickness that becomes thinner as approaching the large diameter portion 8a of the collar member 8. The lip 10a is inclined in a direction approaching the spool 4 as it approaches the large diameter portion 8a of the sleeve member 8, and the tip end is disposed in contact with the large diameter portion 8a of the sleeve member 8. This reduces the contact area of the seal member 10 with the sleeve member 8, and therefore, the reduction in the rotation performance of the sleeve member 8 can be suppressed.

In the dual bearing reel 100 configured as described above, the seal member 10 is disposed in contact with the inner peripheral surface of the bearing housing portion 16a and the outer peripheral surface of the large diameter portion 8a of the sleeve member 8, so that when seawater enters the inside of the right cover 12, the seal member 10 can effectively suppress the adhesion of seawater to the bearing 9. Further, the lubricating oil applied to the reel unit 2 can be effectively inhibited from entering the interior of the bearing 9 by the seal member 10. Further, since the planetary gear 25 is supported by the bearing 9 via the sleeve member 8, the planetary gear 25 can be supported by the bearing 9 with high accuracy.

< embodiments thereof >

While the embodiment of the present invention and the modification thereof have been described above, the present invention is not limited to the embodiment and the modification, and various changes can be made without departing from the spirit of the invention. In particular, the embodiments and the plurality of modifications described in the present specification can be combined as desired.

In the above embodiment, the rotation transmission mechanism 6 has the shift operation mechanism 22, but the shift operation mechanism 22 may be omitted. That is, the 2 nd main gear 24 and the 2 nd planetary gears 26 may be omitted.

In the above-described embodiment, the present invention is applied to a dual-bearing reel having a lever drag mechanism, but the present invention may also be applied to other dual-bearing reels, spinning reels, and other fishing reels. For example, as shown in fig. 4, a bearing 9 that rotatably supports the planetary gear 25 may be disposed in the bearing housing portion 116 of the reel unit 102 of the spinning reel 200 via the sleeve member 8, and the seal member 10 may seal between the inner circumferential surface of the bearing housing portion 161 and the outer circumferential surface of the large-diameter portion 8a of the sleeve member 8. The positions of the bearing housing portions 16a, 161 and the like are not particularly limited. For example, in the spinning reel 200, the bearing supporting the rear end of the planetary gear 25 may be sealed by the seal member 10.
