Description

  The present invention relates to various fishing reels used for fishing, such as spinning reels, double-bearing reels, and electric reels.

  Generally, various sealing structures are used in the fishing reel described above so that foreign matters such as moisture and dust do not enter the inside. The entry of foreign matter is likely to occur at a portion (drive shaft) that is driven to rotate by a handle or driven by a drive motor, and particularly from a bearing portion that rotatably supports the drive shaft. In addition, it is not preferable that foreign matters enter at such a portion in order to maintain the smoothness of driving when the handle is rotated. Therefore, for example, in Patent Document 1, a seal ring is disposed on a bearing end surface that rotatably supports a drive shaft, and axial pressure is applied to an outer ring portion so as to apply pressure to the seal ring. A structure provided with a screw is disclosed.

  Further, for example, Patent Document 2 discloses a structure in which a seal member is provided between a handle shaft and a reel body that are axially outward from the bearing so that foreign matter does not enter the bearing portion. This seal member is formed in a cap shape, and is brought into close contact with the handle shaft by being press-fitted in the radial direction so as to exhibit a sealing effect.

JP 2000-83533 A JP2011-92124A

  Since the sealing member disclosed in the above-described publicly known document is configured to be in sliding contact with the drive shaft and the waterproof portion is frictionally slidable, there is a possibility that the waterproof performance is deteriorated due to wear. That is, when the seal member is worn, moisture easily enters from the portion into the inside (inside the reel body or the bearing), and as a result, the sealing performance cannot be maintained for a long time (not enough as a seal). . Also, in order to enhance the sealing function, it is a wasteful space to dispose another member such as a screw as described above or to secure a space for attaching a cap-shaped sealing member, which increases the size of the reel unit. .

  Further, in order to ensure the sealing performance of the fishing reel more reliably, the bearing itself preferably exhibits a sufficient sealing function. Such a sealing mechanism (seal member) is used when the handle is rotated. It is not preferable that the rotation becomes heavy or vibrations occur. Furthermore, since the seal member is basically composed of an elastic member such as rubber, it is preferable that the seal member can be easily maintained because wear, deterioration, and the like occur when used for a long period of time.

  The present invention has been made paying attention to the above-mentioned problems, and can prevent foreign matter such as moisture from entering the reel body and the bearing with a simple configuration, and can be used when the handle is rotated. An object of the present invention is to provide a fishing reel in which the operational feeling does not deteriorate.

In order to achieve the above object, a fishing reel according to the present invention includes a drive shaft that is rotationally driven when a fishing line is wound around a spool, and the drive shaft includes a main body portion and a lid plate. in a fishing reel that is rotatably supported by a bearing provided on the reel body to be, so as to seal the interior of the pre-Symbol bearings, arranged a sealing mechanism on at least one bearing end face, and the bearing and the drive shaft And an O-ring made of an elastic member between the bearing and the reel body, and a circumferential groove for mounting the O-ring is formed on the outer circumference of the reel body and the drive shaft, respectively. A removable bearing cover is disposed on the outer surface of the main body corresponding to the portion where the drive shaft is supported, and the bearing can be detached from the drive shaft and attached with the bearing cover removed. that with the And butterflies.

  In the fishing reel having the above-described configuration, a drive shaft that is rotationally driven when a fishing line is wound around a spool is rotatably supported in the reel body via a bearing. Further, by providing an O-ring made of an elastic member between the bearing and the drive shaft and between the bearing and the reel body, moisture and dust that enter the reel body along the inner and outer rings of the bearing. It is possible to reliably prevent foreign matters such as. That is, with a simple configuration, the sealing function can be maintained over a long period of time, and a member for applying pressure and a large space are not required, and the reel body is not enlarged. In addition, when the drive shaft rotates, sliding resistance due to the O-ring is not added, so that when the handle is rotated, the rotation does not become heavy, and elastic members are disposed on the inner ring and the outer ring. Thus, vibration is less likely to occur during rotation. In addition, a seal mechanism is provided on at least one bearing end surface to seal the inside of the bearing, so that foreign matter can be prevented from entering the inside of the bearing, and the rotation performance of the bearing can be maintained. It is possible to maintain a smooth rotation of the shaft.

  In the above-described configuration, the drive shaft is rotationally driven by the drive motor, such as a shaft that is rotationally driven when the handle is rotated to wind up the fishing line, and an electric reel. The present invention is intended for various fishing reels (spinning reels, double bearing type reels, electric reels, etc.) having such a drive shaft. Further, when there are a plurality of drive shafts in the reel body, it is only necessary that the bearing disposed on at least one drive shaft has the above-described seal structure. Further, the reel body corresponds to a frame portion that specifies the shape of the reel, and a member that is integrated with the frame (for example, a cover that is attached to the frame, a holding member that holds a component, etc.).

  According to the present invention, it is possible to reliably prevent foreign matter such as moisture from entering the reel body and the bearing with a simple configuration, and for the fishing operation not to deteriorate when the handle is rotated. A reel is obtained.

Hereinafter, embodiments of a fishing reel according to the present invention will be described with reference to the drawings.
FIGS. 1 to 3 are views showing a first embodiment of a fishing reel (spinning reel) according to the present invention, FIG. 1 is a view showing an internal configuration, and FIG. 2 is a fishing shown in FIG. FIG. 3 is an enlarged view showing the seal structure of the bearing shown in FIG. 2.

  A handle shaft (drive shaft) 2 that is rotationally driven by a handle 2A is rotatably supported via a pair of bearings 3 and 3 in the reel body 1 of the spinning reel. A drive gear (drive gear) 4 is attached to the handle shaft 2 so as to be integrally rotatable. The drive gear 4 extends in a direction perpendicular to the handle shaft 2 and can be rotated via a bearing. The teeth of the pinion gear 5 supported by the gears mesh with each other. A rotor nut including a bail 7a and a line roller 7b is attached to the tip of the pinion gear 5 so as to rotate integrally by screwing a rotor nut.

  The pinion gear 5 penetrates along the axial direction, and a spool shaft 9 holding a spool 8 (see FIG. 11) around which a fishing line is wound is inserted through the pinion gear 5. A known oscillating mechanism 10 is connected to the base end side of the spool shaft 9, and when the handle shaft 2 is rotated by a rotation operation of the handle 2 </ b> A, the spool shaft 9 is driven to reciprocate along the axial direction. Is done.

  According to the fishing spinning reel having the above-described configuration, when the handle 2A is rotated, the pinion gear 5 is rotationally driven by the meshing relationship between the drive gear 4 and the pinion gear 5, and the rotor 7 is rotationally driven. Further, the spool shaft 9 is reciprocated in the front-rear direction via the oscillating mechanism 10. That is, as the handle 2A is wound, the spool is reciprocated back and forth with the spool shaft 9 in synchronization with the rotation of the rotor 7, and the fishing line is moved back and forth via the line roller 7b of the rotating rotor 7. Wound evenly.

As described above, a drive shaft (handle shaft, pinion gear, etc.) that is rotationally driven when the handle 2A is rotated is disposed in the reel body 1. In the present embodiment, a seal structure is disposed on the pair of bearings 3 and 3 that rotatably support the handle shaft 2 which is a portion in which foreign substances from the outside easily enter among these drive shafts.
Hereinafter, the seal structure of the present embodiment will be described in detail. In addition, since the bearings 3 and 3 installed on both sides around the spool shaft 9 have the same configuration, the same reference numerals are assigned to the same components.

  The bearing 3 includes an inner ring 3a that is rotatably fitted on the handle shaft side, an outer ring 3b that is rotatably fitted on the reel body side, and a number of rolling members (rolling members) disposed between the inner and outer rings. (Moving body) 3c, and the rolling member 3c is held by a cage 3d. Between the inner ring 3a and the handle shaft 2 and between the outer ring 3b and the reel body 1 (annularly formed inner frame 1a), O-rings 3A and 3B made of elastic members are disposed. Yes. In this case, each O-ring 3A, 3B is mounted with a groove formed in the interposition part so that the mounting state is stable. In this embodiment, a circumferential groove 2b is formed on the outer periphery of the handle shaft 2. In addition, circumferential grooves 1b are formed in the inner frame 1a, and O-rings 3A and 3B are attached to these grooves 2b and 1b.

  In this case, the depth H of each groove 2b, 1b is formed to be slightly smaller than the diameter of the O-rings 3A, 3B attached thereto, and the opening width W of each groove is attached respectively. When the O-rings 3A and 3B are mounted in the grooves 2b and 1b, the O-rings 3A and 3B slightly protrude from the grooves. In the groove, it can be deformed along the axial direction.

  For this reason, when the bearing 3 is fitted along the axial direction with the O-rings 3A and 3B attached to the grooves 2b and 1b, the O-rings 3A and 3B can be crushed while being deformed in the axial direction. As a result, a reliable seal is realized between the handle shaft and the reel body.

  The handle shaft 2 is fitted to the inner ring 3a of the bearing 3 with a slight degree of engagement, and the degree of engagement (backlash) is absorbed by interposing the O-ring 3A. Further, the outer ring 3b of the bearing 3 is also fitted with a slight degree of fitting freedom with respect to the reel body (inner frame), and the degree of fitting (backlash) is absorbed by interposing the O-ring 3B. Has been. That is, with a simple configuration in which O-rings 3A and 3B are installed on the outer peripheral surfaces of the inner and outer rings 3a and 3b of the bearing 3, respectively, the sealing function can be maintained over a long period of time. A member for applying pressure or a large space is not required, and the reel body is not enlarged. Furthermore, by providing O-rings, which are elastic members, on both the inner ring and the outer ring, the degree of play (backlash) between the handle shaft 2 and the reel body 1 and the bearing 3 is absorbed, and vibrations are unlikely to occur during rotation. Thus, the operational feeling during the rotation of the handle is not reduced.

  The O-rings 3A and 3B having the above-described configuration are preferably configured such that the outer ring-side O-ring 3B has a larger diameter than the inner ring-side O-ring 3A (D> d). This is because the O-ring 3B installed on the outer ring side has a larger groove diameter than the O-ring 3A installed on the inner ring side. Since the variation in the crushing amount of the outer ring is inevitably increased, the outer ring side is made larger in diameter than the inner ring side in this way, so that the variation ratio of the crushing amount with respect to the O-ring wire diameter is reduced and stable waterproofing is achieved. It becomes a structure that demonstrates.

  Further, the above-described bearing 3 is provided with a seal mechanism 20 on at least one end face (in this embodiment, both end faces) so as to seal the inside. That is, since moisture (foreign matter) entering from the outside of the reel body easily enters along the surfaces of the inner and outer rings of the bearing 3 as described above, an O-ring is installed on the outer peripheral surface of the inner and outer rings as described above. Thus, the sealing performance can be improved. However, the sealing performance can be further ensured by improving the sealing performance for the inside of the bearing.

In the present embodiment, the seal mechanism 20 is configured as a magnetic seal as follows.
Specifically, the magnetic seal 20 of the present embodiment includes a ring-shaped magnet (hereinafter referred to as a magnet) 22 and a ring-shaped electrode plate (hereinafter referred to as an axially outer surface of the magnet 22). 24) and a magnetic fluid (outer ring-side magnetic fluid 25a, inner ring-side magnetic fluid 25b) held in a magnetic circuit formed by the magnet 22, and by these members, It has a function of sealing so that foreign matter does not enter the rolling member 4c.

  The magnet 22 is attached to the pole plate 24 so as to face the rolling member 4c, and the pole plate 24 has one of an inner surface on the inner ring side and an outer surface on the outer ring side as a fixed side. Note that the magnet 22 of the present embodiment is in a state of being bonded in advance to the electrode plate 24, and the inner peripheral surface 22 a is formed so as not to protrude from the inner peripheral surface 24 a of the electrode plate 24.

  As the magnet 22, a permanent magnet having a high magnetic flux density and a strong magnetic force, for example, a neodymium magnet created by a sintering method can be used, and a magnetic pole (S pole) is previously set in the axial direction (axial direction X of the bearing). , N pole). Further, the electrode plate 24 is disposed in contact with the outer surface of the magnet 22 in the axial direction. The electrode plate 24 has substantially the same shape as the magnet 22 and is formed of a magnetic material, for example, chromium-based stainless steel (SUS440C).

  The magnet 22 and the electrode plate 24 are in a state of being attached at the time of assembly. In this embodiment, both members are bonded in advance, but may not be bonded. In this case, by adhering both in advance, the magnet 22 can be easily positioned and centered, and the magnet 22 and the pole plate 24 are unitized so that the assembling work for the bearing can be easily performed.

  The electrode plate 24 of the present embodiment is press-fitted together with the bonded magnet 22 from the opening side, and the electrode plate 24 bonded with the magnet 22 has a gap between the inner ring 3a when pressed into the opening. The size is such that G is generated. When magnetic fluid is injected into the gap G, the magnetic fluid not only accumulates in the gap G with the inner ring 3a (forms the inner ring-side magnetic fluid 25b), but also travels along the surface of the magnet 22 to the press-fitting side. It is possible to accumulate (form the outer ring-side magnetic fluid 25a).

  Specifically, as shown in FIG. 3, the injected magnetic fluid is held in the gap G between the electrode plate 24 and the inner ring 3a and / or the gap between the magnet 22 and the inner ring 3a. At the same time, the minute gap generated between the magnet 22 and the outer ring 3b and / or the minute gap generated between the electrode plate 24 and the outer ring 3b are held. In other words, the electrode plate 24 to which the magnet 22 is bonded is press-fitted into the outer ring 3b, but a slight gap is generated between the electrode plate 24 and the outer ring 3b due to the influence of dimensional accuracy, production error, and the like. Even in this case, the injected magnetic fluid can flow into the portion, and a reliable seal is formed on both the fixed side and the gap G.

In the injected magnetic fluid (outer ring side magnetic fluid 25a, inner ring side magnetic fluid 25b), for example, magnetic fine particles such as Fe ₃ O ₄ are dispersed in the base oil by the surfactant (the surfactant is coated on the magnetic fine particles). Are dispersed in the base oil), and have a characteristic of reacting when the magnet is brought close to the magnet. For this reason, the magnetic fluids 25a and 25b are stably held at predetermined positions by a magnetic circuit formed between the magnet 22 and the inner ring 3a, the outer ring 3b and the pole plate 24 made of a magnetic material. . In this case, since there is no electrode plate on the rolling member side of the magnet 22, the magnetic fluid easily moves to the press-fitting side to form the outer ring-side magnetic fluid 25a.

According to the configuration of the present embodiment, the O-rings 3A and 3B made of an elastic member are disposed between the bearing 3 and the handle shaft 2 and between the bearing 3 and the reel body 1, and the inner and outer peripheral surfaces of the bearing are disposed. The parts are sealed, and magnetic seals 20 are provided on the openings on both sides of the bearing to completely seal the inside of the bearing and the mounting part, thus reliably preventing foreign matter from entering the reel body (inside the bearing). Therefore, it is possible to maintain the rotational performance of the bearing and maintain the smooth rotation of the handle shaft 2.
In addition, about the magnetic seal 20 of an above-described structure, the structure installed in the one opening end side of the bearing may be sufficient. In this case, it is preferable to install on the exposed side where foreign matter from the outside easily enters.

  The seal mechanism 20A according to this modification is configured by an annular plate 80 installed between the inner ring 3a and the outer ring 3b of the bearing 3 in the opening portion. This plate 80 (rubber seal plate) is formed with a fitting portion 3e on one side (in this embodiment, on the outer ring side), and the circumferential outer edge 80a of the plate 80 is press-fitted into this portion, and the other side (inner ring side) is circular. The circumferential groove 3f is formed, the tip of the circumferential inner edge 80b of the plate 80 is bent and elastically applied to maintain the sealing performance.

  According to such a configuration, since the structure is simple, the cost of the bearing can be reduced, and furthermore, maintenance can be easily performed.

FIG. 14 is a view showing a second modification of the bearing having the seal structure.
In this modification, the sleeve 86 formed inside the base portion 85 of the handle 2A having a non-circular shaft portion 85a fitted to the inside of the handle shaft 2 of the spinning reel and the opening end surface of the bearing 3 having the magnetic seal 20 In addition, labyrinth-structured seal members 88 and 89 are disposed between the two.

  Specifically, the seal member 88 is formed in a cap shape and attached to the end portion of the sleeve 86, and the distal end side is bent toward the seal member 89. The seal member 89 is formed of the outer ring 3 b of the bearing 3. The inner ring side is bent toward the seal member 88 side. In other words, the bent portions 88a and 89a are bent so as to face each other, so that foreign matter is less likely to enter the bearing side from the outside.

  In this way, in addition to the O-rings 3A and 3B and the magnetic seal 20 described above, a labyrinth-structured seal member is further provided to prevent foreign matter from entering the reel body and the bearing more reliably. Can be prevented.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to embodiment mentioned above, It is possible to implement in various deformation | transformation.

  The configuration of the magnetic seal having the above-described configuration is merely an example, and the configuration and arrangement of the magnet and the electrode plate can be modified as appropriate. Further, when attaching the O-ring, a configuration may be adopted in which concave grooves are formed on the surfaces of the inner ring and the outer ring, or a drive shaft may be provided on the outer ring side. Further, the bearing having the above-described seal structure can be disposed on the drive shaft portion of various fishing reels.
