Description

  The present invention relates to a fishing spinning reel, and more particularly to a fishing spinning reel provided with a sealing mechanism.

  A rotor shaft (pinion) as a driving shaft of the spinning reel has a so-called cantilever support structure in which a rotor as a load member is structurally disposed outside two bearings. In general, the cantilevered support structure is more disadvantageous in terms of backlash and load resistance than the double-sided structure in which a load member is disposed between two bearings, but the distance from the load member to the bearing is particularly large. The farther away, the more disadvantageous. For this reason, in the fishing reel disclosed in Patent Document 1, the front bearing is arranged at the forefront of the reel so that the distance between the front bearing and the rotor is closer, so that there is less play and load resistance is advantageous. The structure was realized.

On the other hand, in such an arrangement, there is a problem that the bearing is deteriorated when the front bearing is exposed to splashes of seawater, dust, etc., and the original performance cannot be maintained. In order to prevent this, Patent Document 2 describes that a magnetic fluid is held in a magnetic circuit formed in the gap as a waterproof measure for the gap between the support portion (bearing or the like) of the reel body and the drive shaft. Magnetic sealing has been disclosed, and this magnetic seal has attracted attention as a sealing mechanism that can achieve reliable waterproofing and dust-proofing without friction resistance and wear compared to conventional rubber seals.

  Specifically, in Patent Document 2, the front and rear portions of the tooth portion of the pinion (drive shaft) are supported by a bearing, and a one-way clutch is provided in front of the front bearing to constitute a reverse rotation prevention mechanism. A magnetic seal is formed by holding a magnetic fluid in a magnetic circuit formed in a gap between the pinion (magnetic collar) and the opening of the reel body, thereby forming a one-way clutch that does not cause a reverse play using the wedge action. It is designed to be waterproof and dustproof.

However, in the fishing reel of Patent Document 2, a one-way clutch is disposed between the front bearing and the rotor, and the distance between the rotor portion and the front bearing is increased. It was difficult to suppress the load and improve the load resistance.

  In order to further improve the waterproof performance of the magnetic seal of Patent Document 2 described above, the magnetic field is strengthened by narrowing the gap between the cylindrical magnetic body that rotates integrally with the pinion and the magnet (pole plate). However, it is necessary to increase the pressure resistance (magnetic fluid holding pressure) of the oil film of the magnetic fluid held in the gap. However, since many parts are involved in positioning the pinion magnetic seal, the gap is narrowed. There are also limits.

  Further, in Patent Document 2 described above, the gap position (the front part of the one-way clutch) of the pinion that is magnetically sealed is located farther forward than the front bearing of the pinion, and the front bearing and the rear side The distance to the bearing is shortened (the front bearing and the rear bearing are close). For this reason, it is difficult to maintain the concentricity between the inner periphery of the magnet (electrode plate) constituting the magnetic seal mechanism and the outer periphery of the cylindrical magnetic body that is the drive shaft with high precision (easily decentered). Problems remain in terms of improving and maintaining the pressure resistance of the seal.

  The present invention has been made paying attention to the above-described problems, and provides a spinning reel for fishing that can improve the accuracy of concentricity, thereby suppressing rattling of the rotor and improving load resistance. The purpose is to do. It is another object of the present invention to provide a fishing spinning reel capable of improving the pressure resistance and waterproof performance of a magnetic seal.

In order to achieve the above-described object, the fishing spinning reel of the present invention rotates a drive shaft rotatably provided on the reel body, and a front end side and a base end side of the drive shaft with respect to the reel body. A front-end bearing and a base-end bearing that can be supported, and a seal mechanism that is disposed in the vicinity of the front end side of the front end-side bearing. The reel body partially accommodates the drive shaft. The housing recess is supported by the base end bearing, and the opening of the cover member that partially closes the opening of the housing recess is sealed by the seal mechanism .

  According to the above configuration, the drive shaft is supported by the distal end side bearing and the proximal end side bearing so as to be rotatable between the distal end side and the proximal end side without bringing the bearings too close to each other, so that the rotational behavior of the drive shaft is stabilized. , High accuracy of concentricity of arrangement members around the drive shaft, including functional members (members that control the rotation state of the drive shaft, for example, one-way clutch) located on the base end side of the front end side bearing (Therefore, the function of the functional member itself that controls the rotational state of the drive shaft can be maintained with high accuracy) and the seal mechanism is disposed close to the tip side of the tip side bearing (the seal mechanism is a magnetic seal). In the case of a mechanism, the gap position holding the magnetic fluid of the magnetic seal mechanism is close to the front end bearing), so that the concentricity of the seal mechanism is maintained with high accuracy (the seal mechanism is a magnetic seal mechanism). In case, the magnetic seal Pressure resistance and waterproof performance can be enhanced).

  ADVANTAGE OF THE INVENTION According to this invention, the spinning reel for fishing which can raise the precision of concentricity and can suppress the backlash of a rotor and can improve a load resistance is obtained. In addition, a fishing spinning reel capable of improving the pressure resistance and waterproof performance of the magnetic seal is obtained.

It is an expanded sectional view of the principal part of the spinning reel for fishing of FIG.

  Hereinafter, an embodiment of a spinning reel for fishing according to the present invention will be described in detail with reference to the drawings. In the present specification, the spool 4 side (left side in FIG. 1), which will be described later, is the front end side (front side), and the drive gear 7 side (right side in FIG. 1), which will be described later, is the base end side (rear side). Define the direction.

  1 and 2 show a fishing spinning reel according to a first embodiment of the present invention. As shown in FIG. 1, a reel leg 1 of a fishing spinning reel according to the present embodiment is integrally formed with a reel leg 2 to be attached to a fishing rod, and is rotatably supported in front thereof. A rotor 3 and a spool 4 supported so as to be movable back and forth in synchronism with the rotational motion of the rotor 3 are disposed.

  The rotor 3 includes a pair of arm portions 3a that rotate around the spool 4, and a bail support member 3c having a base end portion of the bail 3b attached to a front end portion of each arm portion 3a is used for winding a fishing line. It is rotatably supported between the position and the fishing line discharge position. One base end portion of the bail 3b is connected to a fishing line guide portion 3d (not shown in FIG. 1; see FIG. 3 according to a second embodiment described later) provided integrally with the bail support member 3c. It is attached.

  A handle shaft 5 is rotatably supported in the reel body 1, and a handle 6 is attached to the protruding end portion. The handle shaft 5 is engaged with a take-up drive mechanism. The take-up drive mechanism has a drive gear 7 mounted on the handle shaft 5 so as to be integrally rotatable, and a meshing portion 19 with the drive gear 7. And a pinion 8 as a cylindrical drive shaft that meshes with each other. The pinion 8 rotatably provided in the reel body 1 extends in a direction orthogonal to the handle shaft 5 and is formed with a hollow portion extending in the axial direction.

  The pinion 8 has a distal end side and a proximal end side rotatably supported with respect to the reel body 1 by a distal end side bearing 9A and a proximal end side bearing 9B, and extends toward the spool 4 side. The rotor 3 is attached to the tip portion so as to be integrally rotatable.

  Further, the pinion 8 has a wedge action at an intermediate portion thereof, specifically, at a proximal end side with respect to the distal end side bearing 9A, more specifically, between the distal end side bearing 9A and the proximal end bearing 9B. A rolling one-way clutch 10 is attached as a functional member for controlling the rotation state of the pinion 8 by using the pinion 8, and the switching operation lever 11 provided on the outside of the reel body 1 is rotated and operated in one direction. A known reverse rotation prevention mechanism is configured to actuate the clutch 10 and prevent the handle 6 (rotor 3) from rotating backward in the direction of fishing line operation.

  In the hollow portion formed inside the pinion 8, the spool shaft 12 extending in the direction orthogonal to the handle shaft 5 and having the spool 4 mounted on the tip side has a slight gap between the inner periphery of the pinion 8. It is inserted so that it can move in the axial direction. The spool shaft 12 is engaged with a known spool reciprocating device 13 for reciprocating the spool 4 (spool shaft 12) back and forth.

  In the fishing spinning reel having such a configuration, when the fishing line winding operation is performed by the handle 6, the rotor 3 is driven to rotate through the winding drive mechanism and the spool 4 is moved through the spool reciprocating device 13. Therefore, the fishing line is evenly wound around the winding body portion 4a of the spool 4 via the fishing line guide portion 3d.

  As clearly shown in FIG. 2, the rolling one-way clutch 10 includes an inner ring 21 that is non-rotatably fitted to the pinion 8, a cage 27 that is disposed outside the inner ring 21, And an outer ring 25 arranged on the outer side.

  A free rotation area where the plurality of rolling members 28 held by the cage 27 can freely rotate and a wedge area where the rotation of the plurality of rolling members 28 are prevented are formed on the inner peripheral surface of the outer ring. Each rolling member 28 is constantly urged toward the wedge region by a spring member provided in the retainer 27.

  In the one-way clutch 10 having such a configuration, when the inner ring 21 rotates forward together with the pinion 8 (the rotor 3 rotates in the fishing line winding direction), the rolling member 28 of the retainer 27 is positioned in the free rotation region of the outer ring 25. Therefore, the rotational force of the inner ring 21 is not transmitted to the outer ring 25 (not blocked by the outer ring 25), and therefore the rotor 3 can rotate without any problem with the pinion 8. On the other hand, when the inner ring 21 is rotated in reverse with the pinion 8 (the rotor 8 rotates in the fishing line steering direction), the rolling member 28 of the retainer 27 is located in the wedge region of the outer ring 25, so The rotational force is transmitted to the outer ring 25, which serves as a stopper, and the rotation (reverse rotation) of the pinion 8 and the rotor 3 is prevented.

  Next, the magnetic seal mechanism 50 disposed in the spinning reel having the above configuration will be described. As clearly shown in FIG. 2, the reel body 1 partially accommodates the pinion 8 (and / or the inner ring 21 that rotates together with the pinion 8) that rotates in conjunction with the operation of the handle 6, and the proximal end side. A housing recess 40 supported by the bearing 9B is formed in a concave shape. The accommodating recess 40 holds the outer ring 25 of the one-way clutch 10 of the above-described reverse rotation prevention mechanism in a non-rotating positioning state and has an opening 40a on the tip side facing the spool 4 side. Since there is a possibility that moisture, foreign matter or the like may enter from the opening 40a, the opening 40a is partially closed by the cover member 42, and the opening 42a through which the pinion 8 partially left by the cover member 42 is inserted A magnetic circuit is formed between the opening 42a and a magnetic portion formed on the outer peripheral surface of the pinion 8 formed of a nonmagnetic material (for example, a copper alloy, an aluminum alloy, etc.), and a magnetic fluid is held therebetween. Thus, the magnetic seal mechanism 50 for sealing the opening 42a is provided in the vicinity (position) of the tip side bearing 9A in the vicinity thereof.

The cover member 42 is formed on the front outer periphery or the front inner periphery of the cylindrical portion 1a that protrudes from the front portion of the reel body 1 by fastening means such as a screw shaft portion 61 formed on the inner periphery of the end portion or a separate screw. It is attached and fixed in the engaged state (the concentricity with respect to the pinion 8 of the magnetic seal mechanism 50 is maintained). In addition, the above-described front end side bearing 9A that supports the pinion 8 is located in the opening 40a of the housing recess 40, but the front end side bearing 9A having an outer diameter smaller than the outer diameter of the one-way clutch 10 can be used. The cylindrical insertion member 63 is disposed in the opening 40a so as to close the opening 40a between the reel body 1 and the front end side bearing 9A.

  The magnetic seal mechanism 50 for sealing the inside of the housing recess 40 for housing the driving elements such as the one-way clutch 10 and the pinion 8 includes a magnet 51 disposed so as to surround the pinion 8 with a predetermined gap. A cylindrical magnetic body 53 that forms a magnetic circuit between an annular pole plate (magnetic ring) 52 to be held and a magnet 51 that is fitted (attached) to the outer periphery of the pinion 8 so as to be integrally rotatable. The magnetic fluid 55 held in the space (gap) between the cylindrical magnetic bodies 53 is configured as one unit (that is, if the cover member 42 is removed from the reel body 1, the magnetic seal mechanism 50 is also formed together with the cover member 42. Can be removed as a unit).

In this case, the magnet 51 is formed in a ring shape having a predetermined thickness so that the pinion 8 can be inserted, and the pole plate 52 sandwiches the magnet 51 so formed from both sides. Configured to hold. The cylindrical magnetic body 53 is formed of an iron-based material, for example, steel, SUS430, SUS440C, SUS630, and the like. Thereby, the magnet 51 holds the electrode plate 52 and the cylindrical magnetic body 53. A magnetic circuit is formed between the two. The magnetic fluid is formed by dispersing magnetic fine particles such as Fe ₃ O ₄ with a base oil surfactant, and has a characteristic of reacting when the magnet is brought close to the magnet.

Here, the effect of the present invention will be described with reference to FIGS. FIG. 3 shows a modification of the first embodiment described with reference to FIGS. Therefore, in FIG. 3, the same components as those in FIGS. 1 and 2 are denoted by the same reference numerals, and the description thereof is omitted. In FIG. 3, the base end side bearing 9 </ b> B is positioned not on the base end side of the one-way clutch 10, but on the base end side thereof and in proximity to the base end of the meshing portion 19. FIG. 4 is a schematic diagram for explaining the effect of the present invention. FIG. 4A is a conventional configuration as shown in Patent Document 2, and FIG. (Corresponding to the configuration of FIG. 3). In the figure, the ideal axis C is the rotation axis of the rotor 3 when the backlash is zero (corresponding to the pinion 8 of the first embodiment), and the eccentric axis C ′ is the rotation axis of the rotor 3 when the backlash is taken into consideration. . Further, d1 and d2 are backlashes in the rear bearing (corresponding to the base end side bearing 9B of the first embodiment) and the front bearing (corresponding to the front end side bearing 9A of the first embodiment), respectively, and D is an evaluation. It is the axis | shaft of the rotor 3 in the location (for example, magnetic seal part) to want. Further, x is the distance from the front bearing to the rear bearing, and L is the distance from the rear bearing to the location to be evaluated.

In each of the bearing portions, play is required to freely support the rotation, but due to this play, the entire shaft is displaced from the ideal axis as in the eccentric shaft C ′. As shown in FIG. 4, this deviation is greatest when the play of the front and rear bearings is shifted to the opposite side, and the amount of play is D = (d1 + d2) L / x-d1. If d1 = d2 = d, the deformation can be made as D = d (2L−x) / x.

As an example, the axial distance of the one-way clutch (one-way clutch 10) is 15 mm, the axial distance of the pinion gear (meshing portion 19) is 15 mm, and the distance L from the rear bearing to the waterproof seal portion is 35 mm. Further, the distance x between the front bearing and the rear bearing in the conventional configuration (FIG. 4A) as shown in Patent Document 2 is 17.5 mm, and the distance x between the front bearing and the rear bearing in the configuration of the present invention is 32. If it is 5 mm, the play D at the waterproof seal portion in FIG. 4A of the conventional configuration is 3d, and the play D at the waterproof seal portion in the present invention is 1.15d. According to the present invention (b) of FIG. 4, the backlash can be reduced to 40% or less without changing the backlash of the bearing portion. Thereby, the play in the waterproof portion can be reduced without relying on costly high-precision processing, and a more reliable waterproof mechanism can be obtained.

The same relationship holds true for the backlash of the rotor portion. As an example, if the distance L from the rear bearing to the rotor is 40 mm and other values are the same as above, the backlash of the rotor portion is 3.57d in the conventional configuration, and the backlash of the rotor portion in the present invention is 1.46d. , About 40%. Thereby, it is possible to obtain a spinning reel that has a smaller rotor shaft backlash and improved durability while ensuring waterproofness.

  As described above and as described with reference to FIG. 4, according to the first embodiment described above, the front end side bearing 9 </ b> A and the base end side bearing 9 </ b> B can be used without bringing the bearings too close together. Since the pinion 8 as a drive shaft is supported rotatably at the distal end side and the proximal end side, the rotational behavior of the pinion 8 is stable, and is a one-way function member that is located on the proximal end side with respect to the distal end side bearing 9A. The concentricity of the arrangement members around the pinion 8 including the clutch 10 can be ensured with high accuracy (therefore, the function of the one-way clutch 10 itself that controls the rotation state of the pinion 8 can be maintained with high accuracy), and the tip Since the magnetic seal mechanism 50 is disposed close to the distal end side of the side bearing 9A, that is, the gap position holding the magnetic fluid 55 of the magnetic seal mechanism 50 is close to the distal end bearing 9A, the magnetic seal mechanism The concentricity of 0 is maintained with high accuracy (therefore, the gap can be narrowed to a desired degree to increase the holding force of the oil film of the magnetic fluid 55 and keep it uniform), and the pressure resistance performance of the magnetic seal mechanism 50 and Waterproof performance can be further enhanced.

  5 and 6 show a fishing spinning reel according to a second embodiment of the present invention. As shown in the figure, also in the present embodiment, as in the first embodiment, the distal end side and the proximal end side of the pinion 8 as a drive shaft are connected to the reel unit 1 by the distal end side bearing 9A and the proximal end side bearing 9B. The pinion 8 is supported so as to be rotatable. Specifically, the pinion 8 is provided at an intermediate portion thereof, specifically, at a proximal end side with respect to the distal end side bearing 9A, and more specifically, at the distal end side bearing 9A and the proximal end side bearing. A rolling type one-way clutch 10 as a functional member for controlling the rotation state of the pinion 8 by utilizing a wedge action is attached between 9B and 9B.

  In the present embodiment, the front end side bearing 9A is formed as a bearing with a magnetic seal. The magnetic seal bearing 9A includes a cylindrical inner ring 70, a cylindrical outer ring 71 surrounding the inner ring 70, and a plurality of rolling elements 72 interposed between the inner ring 70 and the outer ring 71 so as to allow rolling. A bearing body 75 is provided. The rolling element 72 is held by an annular retainer 73, and the inner ring 70 and the outer ring 71 can be rotated relatively.

  The inner ring 70, the outer ring 71, and the rolling element 72 are made of a magnetic material (magnetic body), for example, chromium-based stainless steel (SUS440C), and the cage 73 is a material having excellent corrosion resistance and heat resistance, for example, It is made of stainless steel (SUS304).

  The magnetic seal bearing 9A includes a pair of magnetic fluid seals 80A and 80B. That is, the magnetic fluid seals 80A and 80B are disposed on the both sides in the axial direction of the bearing body 75 with the rolling element 72 interposed therebetween, in the annular space between the inner ring 70 and the outer ring 71, substantially positioned at the opening thereof. Has been. Each of the pair of magnetic fluid seals 80A and 80B is integrally held by the bearing main body 75 (integrated with the bearing main body 75 and configured as a unit together with the bearing main body 75), and the inside of the bearing main body 75 is magnetized. It has a function of sealing.

  Specifically, each magnetic fluid seal 80A, 80B faces the rolling element 72 and is disposed in contact with the ring-shaped magnet 81 disposed on the inner side in the axial direction and the outer surface in the axial direction of the magnet 81. A ring-shaped electrode plate 82 that holds the magnet 81 from the outside in the axial direction, and a magnetic fluid that is held between the inner ring 70 or the outer ring 71 (rotating part) and the magnet 81 (fixed part). This member has a function of sealing so that dust, moisture and the like do not enter the rolling element 72.

  In this case, the magnet 81 is attached to the electrode plate 82 so as to face the rolling element 72, and the electrode plate 82 has either the inner surface on the inner ring 70 side or the outer surface on the outer ring 71 side as a fixed side. Yes. As the magnet 81, a permanent magnet having a high magnetic flux density and a strong magnetic force, for example, a neodymium magnet made by a sintering method, can be used, and the magnet 81 is previously attached so that the magnetic poles (S pole, N pole) face in the axial direction. It is magnetized.

  In this embodiment, a spacer 90 formed of a nonmagnetic material is interposed between the magnetic seal bearing 9 </ b> A and the one-way clutch 10. If such a spacer 90 is interposed, it is possible to avoid the magnetic seal bearing 9 </ b> A from adsorbing the cylindrical magnetic body constituting the one-way clutch 10.

Note that the magnetic seal bearing 9A of this embodiment is supported by being supported in the axial direction by a support body 95 that is detachably fixed to the reel body 1 by a screw member 98. In this way, the bearing 9A can be attached to and detached from the reel body 1 simply by removing the screw member 98, so that the assembly and disassembly of the bearing 9A with a magnetic seal are facilitated.

  Further, in this embodiment, in order to secure the seal inside the reel body 1 including the inside of the housing recess 40, the seal material 92 is interposed between the inner ring 70 and the outer ring 71 of the magnetic seal bearing 9A and the opposing member. Inserted. As such an opposing member, in this embodiment, the inner ring 21 of the one-way clutch 10 interposed between the magnetic seal bearing (tip bearing) 9A and the pinion 8, and the magnetic seal bearing 9A are prevented from coming off. For example, the support 95. The remaining configuration is substantially the same as that of the first embodiment except that the configuration of the switching operation mechanism that operates the one-way clutch 10 is different.

  As described above, according to the second embodiment, the pinion 8 as the drive shaft is connected to the distal end side and the proximal end side by the distal end side bearing 9A and the proximal end side bearing 9B without excessively approaching the bearings. Therefore, the rotational behavior of the pinion 8 is stabilized, and therefore the rotational behavior of the inner ring 70 of the magnetic seal bearing 9A is also stable (as a result, the inner and outer rings 70 and 71 of the magnetic seal bearing 9A are stabilized). (Eccentricity is prevented) and the magnetic fluid oil film holding force of the magnetic seal bearing 9A is increased and kept uniform (as a result, the pressure resistance performance and waterproof performance of the magnetic fluid seals 80A and 80B can be enhanced). Further, the concentricity of the arrangement members around the pinion 8 including the one-way clutch 10 as a functional member positioned on the base end side with respect to the distal end side bearing 9A can be ensured with high accuracy (therefore, the pinion 8). You can maintain the function of the one-way clutch 10 itself for controlling the rotation state with high accuracy).

  As mentioned above, although embodiment of this invention was described, this invention is not limited to embodiment mentioned above, A various deformation | transformation is possible in the range which does not deviate from the summary. For example, in the above-described embodiment, the magnetic seal bearing is used as the seal mechanism, but other seal mechanisms may be used. For example, a V-shaped groove is provided between the rotating part and the fixed part of the bearing, an elastomer made of synthetic rubber or the like is disposed in the groove, and the surface tension, Rolling bearing that uses a labyrinth effect to achieve waterproofing and dustproofing (with a labyrinth-type seal that provides waterproofing and dustproofing by placing a waterproof seal such as an elastomer in the gap between the fixed part and the rotating part with a slight gap between them. Bearings) are known. It is clear that even if such a bearing is used, the same effect as the above-described embodiment can be obtained. The configuration of the magnetic seal mechanism in the present invention is not limited to the configuration of the first embodiment, and includes all configurations that can magnetically seal the inside of the housing recess 40. Further, the configuration of the bearing with the magnetic seal is not limited to the configuration of the second embodiment, and includes all configurations capable of sealing the inside of the bearing. In the present invention, the drive shaft is not limited to a pinion and may be any drive member that rotates in conjunction with the drive shaft, and includes, for example, a handle shaft in a double-axis reel. In the present invention, the functional member that is arranged on the base end side with respect to the front end side bearing and controls the rotation state of the drive shaft is not limited to the one-way clutch, and includes, for example, a ratchet, a motor, and various sensors.
