Description

  The present invention relates to a fishing reel, and more particularly to a fishing reel that rotatably supports a spool around which a fishing line is wound between side plates of a reel body.

  Generally, a fishing reel that rotatably supports a spool between side plates of a reel body is rotatable by a frame of one side plate at a base end portion disposed on a spool side of a handle shaft for winding and driving the spool. In addition, it is prevented from coming off, thereby suppressing the axial movement of the handle shaft during the fishing operation and enabling a smooth operation during the fishing.

  In order to prevent such a handle shaft from coming off, a locking collar is integrally formed in the vicinity of the base end of the handle shaft, and a bearing for supporting the handle shaft is provided in a recess formed in the support plate of the frame. A retaining member provided with a U-shaped groove that is inserted through the handle shaft is screwed to the support plate, so that the locking collar of the handle shaft is brought into contact with the retaining member, and the handle shaft is attached to the frame. There are some which are rotatable and supported by retaining them (see, for example, Patent Document 1).

In addition, the bearing attached to the base end portion of the handle shaft is prevented from coming off by a retaining ring, and the bearing is placed in the recessed portion formed in the support plate of the frame, and the retaining member screwed to the support plate is used to secure the inside of the recessed portion. There is also one that locks the side surface of the outer ring of the bearing to prevent it from coming off (see, for example, Patent Document 2).

  However, when the locking collar part integrally formed with the handle shaft is brought into contact with the retaining member to prevent the retaining collar part from sliding, the locking collar part that rotates together with the handle shaft slides while rubbing the retaining member. As a result of the rotational resistance of the handle shaft, the smooth and light rotation performance of the handle is hindered.

  In order to improve the rotation performance of the handle shaft, if a gap is provided between the locking hook portion and the retaining member, the handle can be moved in the axial direction, and the following disadvantageous states occur. .

  First, the sense that the angler perceives from the fishing line through the spool and handle shaft is reduced, and the lure movement during guidance operation becomes difficult to understand during actual fishing (accuracy of lure action, slowing of sensitivity).

  Secondly, it is difficult to understand the catch of fish (fish trust, reduced sensing ability).

  Third, quick and reliable hooking operation is hindered (usually, it is performed with the palming with one hand and the handle operated with the other hand, and the axial movement of the handle at this time is aligned with the hooking. Reduce certainty).

  Fourth, damage to the meshing surface with the pinion gear due to axial movement of the drive gear is likely to occur, and this meshing surface damage reduces the rotational performance.

  On the other hand, when the outer ring member of the bearing is brought into contact with the retaining member and retained, the frictional resistance is extremely small, but the axial direction between the retaining ring attached to the base end portion of the handle shaft and the bearing is small. The play causes play and causes the axial movement of the handle shaft, causing the above-mentioned disadvantageous situation.

  In order to improve the inconvenience due to such play, when a washer or the like is inserted between the bearing attached to the base end of the handle shaft and the retaining ring in a press-fit state, the bearing and retaining ring are mounted on the handle shaft. The backlash between can be suppressed.

  However, when the frame is mounted on the support plate in this state, a force in the opposite direction acts on the outer ring from the retaining member, and a load exceeding the allowable value is applied between the inner and outer rings of the bearing in the thrust direction. Such a thrust load causes the inner and outer rings to bend, and the ball raceway surface is likely to be hit and damaged, resulting in a decrease in the rotational performance of the bearing (occurrence of sticking) and a decrease in durability.

  The present invention has been made based on such circumstances, and an object of the present invention is to provide a fishing reel capable of preventing the axial movement of the handle shaft while maintaining smooth handle rotation. .

  The fishing reel of the present invention that achieves the above object is characterized in that a spool is rotatably supported between side plates of a reel body, and a base end portion disposed on a spool side of a handle shaft for winding and driving the spool is provided on one side. A fishing reel that is rotatably supported by a frame on the side plate side of the side plate, and includes a rolling bearing attached to a base end portion of the handle shaft, and a locking member that locks the inner ring of the rolling bearing. A bearing unit that is recessed in the frame and accommodates the bearing unit; and a rolling bearing that is attached to a peripheral edge facing the opening end of the bearing accommodation hole and accommodated in the bearing accommodation hole. A support portion having a retaining member that forms a floating gap with the outer ring, and when the bearing unit is mounted on the support portion, the support portion is interposed between the bottom wall of the bearing receiving hole and the base end surface of the handle shaft. Inserted Biasing the handle shaft distally to move the handle shaft over a distance corresponding to the floating gap, characterized by comprising an urging member for removing the floating gap.

  This fishing reel is inserted between the bottom wall of the bearing receiving hole and the base end surface of the handle shaft when the bearing unit disposed at the base end portion of the handle shaft is attached to the support portion of the frame. The biasing member biases the handle shaft toward the distal end, moves the handle shaft over a distance corresponding to the free clearance, and removes the free clearance, thereby reliably preventing the axial movement of the handle shaft. This increases the accuracy of the lure action operation during actual fishing and the reliability at the time of hooking, can suppress the occurrence of scratches on the meshing surface of the drive gear and pinion gear, and does not apply excessive load to the bearing Smooth, good handle rotation can be maintained.

  1 to 4 show a fishing reel 10 according to a preferred embodiment of the present invention.

  As shown in FIG. 1 as a whole, the fishing reel 10 of this embodiment is formed as a double-bearing type manually wound reel. The reel body 12 of the fishing reel 10 is formed in a circular shape or by a coupling means such as a screw, screwing or fitting on the outside of each of the pair of left and right frames 14a and 14b integrated by a connecting member or the like. Cylindrical side plates 16a and 16b are attached to form a rigid housing as a whole, and are fixed to a fishing rod via attachment legs (not shown). The right side plate 16b of the present embodiment is fixed to the right frame 14b by a fixing ring 17a and screws 17b (see FIG. 2).

  Note that the left and right terms indicate the left and right direction in FIG. 1 for convenience of explanation, and do not indicate the left and right direction in an actual fishing reel. For example, in contrast to the fishing reel in the illustrated embodiment, when the hand-wound handle is arranged on the left, the horizontal direction in this specification may be reversed.

  The spool 18 around which the fishing line is wound is rotatably supported between the left and right frames 14a and 14b, and the right side plate 16b supports a winding drive unit 20 that drives the spool 18 to rotate. In the space partitioned by the frame 14b, a winding drive unit 20 including various mechanisms such as a driving force transmission system and a drag system for transmitting a driving force to the spool 18 is accommodated.

  As shown in FIGS. 1 and 2, the spool 18 is integrally formed with a spool shaft 18a rotatably supported at both ends via ball bearings 22a and 22b mounted on the frames 14a and 14b of the reel body 12. And is provided so as to be freely rotatable with the spool shaft 18a with respect to the reel body 12. A pinion 26 is fitted on the outer periphery of the pressing shaft 24 arranged coaxially with the spool shaft 18a, and is rotatable with respect to the right plate 16b and the right frame 14b via ball bearings 28a and 28b. The pressing shaft 24 is supported by the reel body 12 by the pinion 26 supported so as to be movable in the direction. The pressing shaft 24 abuts on the right end of the spool shaft 18a in the reel body 12, and the pressing force of the adjusting screw 30 provided on the right plate 16b is applied to the spool shaft 18a to prevent the spool 18 from rattling. However, it is held at a predetermined position in the axial direction.

  The pinion 26 has a cylindrical structure through which the pressing shaft 24 is inserted. The pinion 26 meshes with a drive gear 20a provided in the winding drive unit 20, and the rotational driving force of the handle 32 is spooled via the drive gear 20a. 18 is transmitted.

  The handle 32 is fastened and fixed to one end of a handle shaft 34 arranged in parallel with the spool shaft 18a and the pressing shaft 24 by a tightening nut 32a, and can be rotated by the right frame 14b and the right side plate 16b via the handle shaft 34. Supported. The handle shaft 34 is operated to turn on and off the clutch mechanism 38 via the clutch lever 36 and the link 37 disposed between the left and right frames 14a and 14b, so that the pinion 26 is as shown in FIGS. It is possible to move between an engagement position that fits with the spool shaft 18a and rotates integrally with the spool shaft 18a, and a non-engagement position in which the engagement state with the spool shaft 18a is released.

  The movement of the pinion 26 can be performed by moving the yoke 39 that engages with the circumferential groove 26a formed in the pinion 26 along the pinion shaft 26a in conjunction with the ON / OFF operation of the clutch mechanism 38. When the pinion 26 is arranged at the engaged position shown in FIGS. 1 and 2, the clutch-on fishing line can be wound, and at a non-engaged position (not shown), the clutch is turned into a spool-free rotation state. A magnetic braking device that prevents backlash by preventing over-rotation of the spool 18 when the fishing line is released in a clutch OFF state in which the spool 18 can freely rotate, for example, a spool shaft 18a protruding from the left frame 14a. It can also be provided at the end of the.

  As will be described later, the handle shaft 34 that transmits the rotation of the handle 32 to the pinion 26 is supported by a base end portion 76 disposed on the inner end side so as to be rotatable and prevented from being detached, and the handle 32 is fixed. The tip is rotatably supported by a bearing 40 on a cylindrical protrusion 16c of the right side plate 16b. A one-way clutch 42 that allows rotation of the handle shaft 34 in the direction of winding the fishing line and prevents rotation in the reverse direction is disposed in the protrusion 16c.

  Further, a clutch that returns to the clutch-on state when the handle 32 is rotated in a state where the pinion 26 is separated from the spool shaft 18a is provided at a portion close to the base end portion 76 supported by the right frame 14b of the handle shaft 34. A return ratchet gear 44 and an interlocking gear 46 are supported. The ratchet gear 44 is non-rotatably fitted to the non-circular section 34 a of the handle shaft 34, and is supported by a flange portion 35 integrally formed on the handle shaft 34 on the inner end side thereof. The interlocking gear 46 is rotatably supported by the handle shaft 34, and a projection 46a protruding toward the handle 32 is a hole that opens on the side surface of the drive gear 20a that is rotatably supported on the handle shaft 26a. And can rotate integrally with the drive gear 20a.

  Further, the interlocking gear 46 meshes with a gear 50 a that drives a worm shaft 50 of a level wind mechanism 48 disposed on the front side of the spool 18. The worm shaft 50 is accommodated in a cylindrical body 52 extending between the left and right frames 14a, 14b, and a traverse formed on the outer peripheral surface when the gear 50a attached to the end is rotated by the interlocking gear 46. An engagement element 54 that engages with the groove slides left and right along the cylindrical body 52. As a result, the fishing line is evenly wound on the spool 18 through the guide hole 54 a formed in the engagement element 54.

  The drive gear 20a to which the interlocking gear 46 is coupled is formed in a cylindrical shape having an opening on the handle 32 side, and a drag mechanism 56 is provided between the drive gear 20a and the handle shaft 34. The drag mechanism 56 is housed in the internal space of the drive gear 20a, rotates integrally with the drive gear 20a, and is movable in the axial direction, and rotates integrally with the handle shaft 34 and is movable in the axial direction. A drag operation member 58 having a multi-plate structure in which the shaft-side brake plates 56b are alternately arranged and a lining material is inserted between the brake plates 56a and 56b and screwed to the outer end side of the handle shaft 34. Is rotated between the drive gear 20a, which is axially restricted by the flange portion 35 on the inner end side, via the sleeve 60 and the disc spring 62 disposed on the inner peripheral side of the one-way clutch 42. The plates 56a and 56b can be pressed in the axial direction to apply a frictional coupling force of the drive gear 20a to the handle shaft 34, that is, a desired drag force to the spool 18 that is driven and rotated.

  That is, by rotating the handle 32, the driving force is transmitted to the spool 18 via the drag mechanism 56 via the drive gear 20a, the pinion gear 26, and the spool shaft 18a. When the fish catches, if the force that rotates the spool 20 in the fishing line discharge direction exceeds the drag force, the drive gear 20a rotates against the drag force, and the spool 18 rotates in the fishing line feeding direction, and breaks the thread. To prevent. This drag force is adjusted by operating the drag operation member 58.

  As described above, the handle shaft 34 that transmits the rotational force of the handle 32 to the spool 18 is such that the base end portion on the inner end side is freely rotatable and prevented from being detached from the right frame 14b that fixes the right side plate 16b on the handle 32 side. Supported by For this reason, the right frame 14b is provided with a support portion 64 that supports the proximal end portion of the handle shaft 34 at a position coaxially aligned with the protruding portion 16c of the right side plate 16b.

  As shown in FIGS. 3 and 4, the support portion 64 has a bearing receiving hole 66 opened to the side plate 16b side, and the bearing receiving hole 66 has a small diameter portion 66a on the bottom side and an opening side. And a bearing unit 68 provided at the base end portion 76 of the handle shaft 34 is mounted.

  The bearing unit 68 of the present embodiment includes a rolling bearing 70 attached to the base end portion 76 of the handle shaft 34 and a plate-like locking member 72 that locks the rolling bearing 70 and holds it on the handle shaft 34. Have. The base end portion 76 of the handle shaft 34 that forms the bearing unit 68 together with the rolling bearing 70 and the locking member 72 has three outer peripheral circular portions whose outer diameters are reduced in order from the flange portion 35 toward the base end surface 74. Stepped portions 76a, 76b, and 76c are formed, the rolling bearing 70 is mounted on the intermediate stepped portion 76b, and the annular groove 78 formed in the smallest diameter stepped portion 76c has, for example, a C-ring-shaped notch. A plate-like locking member 72 having an opening is fitted. Further, the largest diameter step portion 76 a adjacent to the flange portion 35 forms an axial gap between the bearing unit 68 and the flange portion 35 for disposing a retaining member 80 described later.

  In order to enable smooth rotation of the handle shaft 34, it is important not to apply unnecessary stress to the rolling bearing 70 of the bearing unit 68. For this reason, the inner ring of the rolling bearing 70 is formed on the stepped portion 76b. It is desirable to be able to move slightly in the axial direction. In other words, the locking member 72 fitted in the annular groove 78 allows the inner ring of the rolling member 70 to move in the axial direction between the stepped portion 77 forming an annular surface between the stepped portions 76a and 76b. It is preferable to form the gap P1 (see FIG. 4). This free gap P1 can be set to an appropriate size as long as it can prevent axial stress on the inner ring of the rolling bearing 70. For example, if the gap is positively formed, However, it is preferably set to about 0.05 to 0.3 mm.

  If the base end portion 76 of the handle shaft 34 forms an axial gap C for disposing the retaining member 80 and the bearing unit 68 can be mounted between the flange portion 35 and the base end portion 76, Instead of providing the stepped portions 76a, 76b, 76c, the inner ring of the rolling bearing 70 may be held in contact with the plate-like locking member 72 on both sides in the axial direction.

  The bearing unit 68 on the base end portion of the handle shaft 34 assembled in this way accommodates the stepped portion 76c and the locking member 72 constituting the outer peripheral circular portion of the small diameter in the small diameter portion 66a of the bearing accommodating hole 66, and rolls. The outer ring of the bearing 70 is accommodated in the large-diameter portion 66b, and the right frame 14b is prevented from being detached by a retaining member 80 fixed to the right frame 14b by a set screw 82 on the side where the bearing housing hole 66 is opened. The support part 64 is attached.

  The retaining member 80 that holds the bearing unit 68 in a state in which the bearing unit 68 is retained in the bearing receiving hole 66 is formed in a plate shape, is smaller than the inner diameter of the outer ring of the rolling bearing 70, and is outside the inner ring and the stepped portion 76 a. A U-shaped groove 84 formed with a width larger than the diameter is provided, and the U-shaped groove 84 is inserted into the gap C between the bearing unit 68 and the flange portion 35 from the opening end side of the U-shaped groove 84. , And can be fixed to the right frame 14b with a set screw 82. The retaining member 80 fixed to the right frame 14b has a peripheral portion of a U-shaped groove 84 protruding radially inward of the large-diameter portion 66b so that the outer ring of the rolling bearing 70 is locked. It is prevented from coming out of the receiving hole 66.

  The large-diameter portion 66b of the bearing receiving hole 66 is formed to have a depth, that is, an axial dimension slightly larger than the outer ring of the rolling bearing 70, and thereby the loose clearance P2 along the axial direction in which the rolling bearing 70 can move. Form. The loose gap P2 reliably prevents the urging force of the set screw 82 from acting on the outer ring member of the rolling member 70 when the retaining member 80 is fixed to the right frame 14b with the set screw 82. As a result, no axial stress is formed on the outer ring, and the smooth rotation performance of the rolling bearing 70 is ensured together with the inner ring mounted with the idle clearance P1 as described above, and the ball is applied to the raceway surface. It is possible to suppress the occurrence of bending of the inner and outer rings, which is a major cause of deterioration of the rotational performance and durability of the bearings, scratches, and the like. This floating gap P2 only needs to be able to prevent stress from being generated in the outer ring of the rolling bearing 70. For example, it does not form a gap in the active liquid and is extremely small, such as about 0.05 to 0.3 mm. It is preferable to form with a gap.

  Note that the depth of the small diameter portion 66a is such that the base end surface 74 abuts against the bottom wall 66d of the small diameter portion 66a even when the handle shaft 34 moves to the base end side by a distance corresponding to the above-described floating gaps P1 and P2. It is preferable to prevent the occurrence of scratches and the like due to contact between metals.

  Further, such a floating gap P1, P2 prevents the handle shaft 34 from freely moving in the axial direction during actual fishing, and prevents the above-described disadvantages from occurring, so that the bottom wall 66d of the bearing receiving hole 66 is prevented. An urging member 86 for urging the proximal end surface 74 of the handle shaft 34 toward the distal end side on the handle 32 side is disposed in the positioning hole 66c formed in FIG. The positioning hole 66c is arranged coaxially with the large-diameter portion 66b, and this urging member 86 presses the proximal end surface 74 of the handle shaft 34 toward the distal end, thereby causing the handle shaft 34 to correspond to the floating gaps P1 and P2. Thus, the locking member 72 comes into contact with the wall portion of the groove 78 on the spool 18 side, the locking member 72 comes into contact with the inner ring of the rolling bearing 70, and the outer ring contacts the retaining member 80. Touch.

  The urging member 86 generates an urging force that moves by a distance corresponding to the idle travel distances P1 and P2 in order to prevent excessive stress from being generated in the rolling bearing 70. In this embodiment, the urging member 86 is felt. It is formed. In the case of forming with such a felt, the elastic deformation may be made constant by compression, or the frictional force with the base end face 74 may be reduced by impregnating with resin or lubricant.

  In this fishing reel 10, when the bearing unit 68 disposed at the base end portion 76 of the handle shaft 34 is mounted on the support portion 64 disposed at the right frame 14b, the bottom wall 66d of the bearing receiving hole 66 and the handle shaft An urging member 86 inserted between the base end surface 74 of the boss 34 urges the handle shaft 34 toward the distal end side, and moves the handle shaft 34 over a distance corresponding to the loose gaps P1 and P2. The play of the handle shaft 34 caused by the loose gaps P1 and P2 between the biasing member 86 and the retaining member 80 is substantially eliminated. As a result, the axial movement of the handle shaft 34 is reliably prevented, the accuracy of the lure action operation during actual fishing and the reliability at the time of hooking are increased, and scratches on the meshing surface between the drive gear 20a and the pinion gear 26 Occurrence can also be suppressed, and an excessive load does not act directly in the thrust direction of the rolling bearing 70, so that the rotational performance of the smooth rolling bearing 70 can be maintained, and smooth and favorable handle rotation can be maintained. .

  5 and 6 show a support part 64 in another embodiment. Since various embodiments or modifications described below are basically the same as those in the above-described embodiment, the same parts are denoted by the same reference numerals, and detailed description thereof is omitted.

  In the embodiment of FIG. 5, the biasing member 86 </ b> A is formed by a curved leaf spring, and the proximal end surface 74 of the handle shaft 34 is pressed toward the distal end side by the curved top surface. By forming the urging member 86A in a curved shape, the frictional contact force with the base end surface 74 is extremely small, and a smoother steering performance can be obtained.

  In the embodiment of FIG. 6, the urging member 86B is formed of an elastic material such as rubber, and a low friction resin or metal cover member 88 is mounted on the outer surface on the base end face 74 side. By forming a gap or the like in the urging member 86B, the urging force can be adjusted to a required magnitude.

  Although the preferred embodiments of the present invention have been described above, it is obvious that various modifications or changes can be made without being limited thereto. For example, the biasing member may be attached to the proximal end surface 74 of the handle shaft 34.
