Description

  The present invention relates to a fishing spinning reel which rotates a rotor by rotating a handle and winds a fishing line on a spool through a fishing line guide provided on the rotor.

  Generally, a fishing spinning reel is attached and fixed to a fishing rod via a rod attachment portion formed at an end portion of a leg portion extending from the reel body. A handle shaft to which the handle is fixed is rotatably supported on the reel body. A drive gear is fixed to the handle shaft, and is formed on the outer periphery of the base end portion of the drive cylinder shaft that extends in a direction orthogonal to the handle shaft and is rotatably supported by the reel body. The tooth portion (pinion gear) thus engaged meshes. The drive cylinder shaft is supported via a rolling bearing that restricts movement in the axial direction, and a rotor is integrally attached to the tip, and the inside of the drive cylinder axis extends in a direction perpendicular to the handle shaft. The spool shaft penetrates. Further, a spool around which a fishing line is wound is attached to the tip of the spool shaft. The spool shaft is reciprocated along a direction orthogonal to the handle shaft by a spool reciprocating mechanism (oscillating mechanism) that converts the rotational force from the handle into the longitudinal movement of the spool shaft (for example, Patent Document 1 and Patent Document). 2).

As described above, the fishing spinning reel is configured such that by rotating the handle, the spool shaft is moved back and forth while rotating the rotor, and the fishing line is wound around the spool through the fishing line guide portion of the rotor. During the winding operation, a load is applied to the drive cylinder shaft through the rotor from the fishing line wound around the spool. Normally, the rolling bearing that rotatably supports the drive cylinder shaft is fixed to the reel body via a fixing member, and the inner ring is sandwiched between the drive cylinder shaft and the rotor so that the drive cylinder shaft moves in the axial direction. And the rotor is fixed to the drive cylinder shaft to support the rotor at a predetermined position.

  However, in order to achieve smooth rotation, the rolling bearing generally forms a slight clearance between the inner ring and the outer ring and the rolling elements disposed between the inner and outer rings. For this reason, the inner ring and the outer ring have minute backlash in the axial direction, and this backlash causes a minute backlash on the drive cylinder shaft that is axially regulated by the rolling bearing.

  On the other hand, since the rotor fixed to the drive cylinder shaft supports the fishing line guide portion only on one arm portion of the pair of arm portions opposed to each other in the radial direction, unbalance occurs during rotation. . The balance structure that eliminates this unbalance is also described in Patent Document 1 described above, but it is difficult to completely eliminate the unbalance, and a minute unbalance remains.

For this reason, minute vibrations are constantly generated during the rotation of the rotor, and these vibrations cause the rolling bearings to be steadily generated. Such vibration of the rolling bearing is also transmitted to the reel body and the fishing rod, and during the winding operation, the angler feels unpleasant minute vibrations through the hand holding the fishing rod, which makes the operation feeling poor and long. It causes tired hands in actual fishing time.
Further, if the rolling bearing continues to be rattled for a long period of time, the wear of the rolling bearing is promoted and the service life may be shortened.

  The present invention has been made based on such circumstances, and an object thereof is to provide a fishing spinning reel that can suppress vibration transmitted to the angler's hand and extend the service life.

  In order to achieve the above object, according to the present invention, a drive cylinder shaft that rotates in conjunction with a handle is rotatably supported on the front portion of a reel body via a rolling bearing that restricts axial movement. A spool for winding and holding a fishing line is provided at the front portion of the spool shaft that is inserted into and inserted into the rotor, and by rotating the handle, the rotor fixed to the drive cylinder shaft is rotated together with the drive cylinder shaft. A fishing spinning reel that winds a fishing line around the spool through a provided fishing line guide portion, wherein the driving cylinder shaft is disposed along an axial direction of the spool shaft between the driving cylinder shaft and a support portion of the reel body. There is provided a fishing spinning reel in which an elastic member that is biased is inserted to prevent backlash between inner and outer rings of the rolling bearing.

  According to the present invention, an elastic member that urges the drive cylinder shaft along the axial direction of the spool shaft is interposed between the drive cylinder shaft and the reel body, so that the elastic member is connected to the shaft of the drive cylinder shaft. It absorbs the vibration of the rotor that occurs due to the minute back and forth movement of the drive cylinder shaft that occurs due to backlash between the inner and outer rings of the rolling bearing that restricts the direction movement, and the slight imbalance that occurs when the rotor rotates. This prevents vibrations from being transmitted to the angler via the reel body, prevents the angler from feeling uncomfortable, and extends the service life of the rolling bearing by suppressing the play of the rolling bearing. it can.

1 to 3 show a fishing spinning reel 10 according to a preferred embodiment of the present invention.
The spinning reel 10 for fishing according to the present embodiment includes a reel body 12a having a rigid structure, a leg portion 12b extending from the reel body 12a, and a rod attachment portion 12c formed at an end of the leg portion 12b and attached to a fishing rod. And have. A winding drive mechanism for winding the fishing line around the spool 14 is provided in the reel body 12a. Specifically, a handle shaft 18 to which the handle 16 is fixed is rotatably supported in the reel body 12a. A drive gear 20 is fixed to the handle shaft 18, and a pinion gear 22 a meshes with the drive gear 20.

  The pinion gear 22a is provided on the drive cylinder shaft 22 that extends in a direction orthogonal to the handle shaft 18 and is rotatably supported on the reel body 12a via bearings 24a and 24b described later. A rotor 28 having a bail 26 and a fishing line guide 27 is integrally attached to the tip of the drive cylinder shaft 22.

  A spool shaft 30 extending in a direction orthogonal to the handle shaft 18 passes through the drive cylinder shaft 22. The spool shaft 30 is arranged concentrically with the drive cylinder shaft 22 and can move back and forth in the drive cylinder shaft 22 along a direction orthogonal to the handle shaft 18. The spool 14 for winding a fishing line is attached to the tip of the spool shaft 30.

  The handle shaft 18 is formed with a gear 36 that meshes with the interlocking gear 34 of the oscillating mechanism (reciprocating mechanism) 32. The oscillating mechanism 32 of this embodiment is of a so-called gear type, and is interlocked with a gear 36 that rotates in conjunction with the gear 36, and a projection that protrudes from the interlocking gear 34 and is offset from the rotation center axis of the interlocking gear 34. Engagement protrusion 34a positioned at the center, slider 38 having a cam groove 38a attached to the rear end portion of spool shaft 30 via screw 31 and engaging with engagement protrusion 34a, and engagement with slider 38 In addition, a guide rail 40 for guiding the reciprocation of the slider 38 is provided. In such an oscillating mechanism 32, when the handle shaft 18 is rotated by the rotation operation of the handle 16, the interlocking gear 34 that meshes with the gear 36 on the handle shaft 18 rotates, and accordingly, the interlocking gear 34 is engaged. As the projection 34a rotates, the slider 38 reciprocates back and forth by the guide of the cam groove 38a engaged with the engagement projection 34a. Therefore, the spool shaft 30 attached to the slider 38 is reciprocated (back and forth) along the axial direction.

  According to the above configuration, when the handle shaft 18 is rotated by rotating the handle 16, the spool 14 attached to the spool shaft 30 reciprocates back and forth via the oscillating mechanism 32, and the drive gear 3, The rotor 28 is rotationally driven via the pinion gear 22 a and the drive cylinder shaft 22. Accordingly, the fishing line is evenly wound around the spool 14 via the fishing line guide portion 27.

  Further, the end portion of the switching rod 42 of the reverse rotation prevention mechanism having a well-known one-way clutch 40 that prevents reverse rotation (rotation in the fishing line feeding direction) of the rotor 28 passes through the rear end wall portion 13 of the reel body 12a. A switching lever 42a is attached to the end of the switching rod 42 that protrudes outward from the rear end wall 13. Through this switching lever 42a, the rotor 28 can be switched between a state in which forward and reverse rotation is possible and a state in which forward rotation is possible and reverse rotation is impossible. In addition, the one-way clutch 40 includes an inner ring 40a that is non-rotatably fitted to the drive cylinder shaft 22, a retainer 40b that is disposed outside the inner ring 40a and holds a plurality of rolling members R, and a retainer 40b. And an outer ring 40c arranged on the outer side of the outer ring.

  In the present embodiment, the rotor 28 is clamped and fixed between, for example, a hexagon nut 44 that is screwed to the tip of the drive cylinder shaft 22 and the inner ring 40 a of the one-way clutch 40. A female screw 44 a is formed on the inner peripheral surface of the shaft portion of the hexagonal nut 44, and the female screw 44 a is screwed to a male screw formed on the outer peripheral surface of the distal end portion of the drive cylinder shaft 22. 44 is fastened to the drive cylinder shaft 22. The outer peripheral surface of the head portion of the hexagon nut 44 is engaged with the head portion of a screw member 45 screwed into the rotor 28, and the rotation of the hexagon nut 44 is prevented by the screw member 45.

  As shown in an enlarged view in FIG. 2, a concave annular housing groove 44 b is formed on the inner peripheral side of the head of the hexagon nut 44. A rolling bearing 48 that rotatably supports the spool shaft 30 via a resin collar 46a is housed in the housing groove 44b. In this embodiment, in order to prevent the rolling bearing 48 from coming out of the receiving groove 44 b, a countersunk machine screw 49 is screwed into the end face of the hexagon nut 44, and the rolling is performed via the head of the countersunk machine screw 49. The bearing 48 is locked. At the rear part of the drive cylinder shaft 22, the spool shaft 30 is supported by the drive cylinder shaft 22 and the reel body 12a via a resin collar 46b, and is therefore arranged in front of and behind the drive cylinder shaft 22. An extremely slight gap S is formed between the inner peripheral surface of the drive cylinder shaft 22 and the outer peripheral surface of the spool shaft 30 by the two resin collars 46a and 46b. Thereby, the friction between the drive cylinder shaft 22 and the spool shaft 30 is reduced, and the drive cylinder shaft 22 and the rotor 28 rotate smoothly and integrally in conjunction with the rotation of the handle 16.

  As shown in FIGS. 2 and 3, the drive cylinder shaft 28 of the present embodiment is supported on the front portion of the reel body 12 a by two rolling bearings 24 a and 24 b in a state where movement in the axial direction is restricted.

  Specifically, the drive cylinder shaft 22 of the present embodiment has a stepped structure formed on the reel body 12a, in which the outer diameter of the pinion gear 22a is larger than that of the cylinder portion 22b and the rear end support portion 22c. A rolling bearing 24a fitted in the housing recess 15 and prevented from moving backward supports the cylindrical portion 22b on the front side of the pinion gear 22a with a pinion gear 22a via a washer 50. A holding plate 54 that holds the washer 52 and the one-way clutch 40 in the reel body 12 a is fixed to the reel body 12 a by a fixing screw 56 on the front side of the rolling bearing 24 a, that is, the tip side. This prevents the rolling bearing 24a from moving forward and backward, and the drive cylinder shaft 22 is restricted from moving axially forward by the rolling bearing 24a engaged via the pinion gear 22a and the washer 50. Is done. In the present embodiment, the rear washer 50 inserted between the pinion gear 22a and the inner ring of the rolling bearing 24a is engaged with the front washer interposed between the outer ring 40c of the one-way clutch 40. 52 is engaged with the outer ring of the rolling bearing 24a, but this can be reversed.

  Further, the rolling bearing 24b that supports the rear end support portion 22c of the drive cylinder shaft 22 is accommodated in the support portion 17 formed integrally with the reel body 12a. The support portion 17 includes a concave portion 17a that fits the outer ring of the rolling bearing 24b, and a flange portion 17b that protrudes radially inward from the outer peripheral portion on the rear end side of the concave portion 17a. The resin collar 46b is sandwiched between the outer ring of the bearing 24b. As a result, the backward movement of the rolling bearing 24b is prevented, and the axial movement of the drive cylinder shaft 22 to the rear side is restricted by the rolling bearing 24b engaged through the pinion gear 22a.

  A spring washer 56 is interposed between the inner ring of the rolling bearing 24b accommodated in the support portion 17 and the pinion gear 22a, and the spring washer 56 extends along the axial direction of the spool shaft 30 as an elastic member. The drive cylinder shaft 22 is urged forward, that is, the tip side. As a result, the bearing 24a and the spring washer 56, which is an elastic member, are inserted between the support portion 17 of the reel body 12a and the drive cylinder shaft 22. As a result, the rolling bearing 24a disposed at the front is urged toward the front side while the outer ring is held by the reel body 12a, while the rolling bearing 24b disposed at the rear engages the outer ring with the reel body 12a. The inner ring is urged rearward while being stopped. Therefore, a slight gap formed between the inner ring and the outer ring of the rolling bearings 24a and 24b is eliminated.

  The spinning reel 10 for fishing thus formed has a spring washer 56 that urges the drive cylinder shaft 22 along the axial direction of the spool shaft 30 interposed between the reel main body 12a and the spring washer 56. Further, the minute back and forth movement of the drive cylinder shaft 22 caused by the backlash between the inner and outer rings of the rolling bearings 24a and 24b regulating the axial movement of the drive cylinder shaft 22 is absorbed. Furthermore, the vibration of the rotor caused by a slight imbalance when the rotor 28 coupled to the drive cylinder shaft 22 rotates is also absorbed by the spring washer 56. Therefore, for example, during the winding operation, vibrations caused by the rolling bearings 24a and 24b and the rotor 28 are prevented from being transmitted to the angler's hand through the reel body 12a, thereby preventing the angler from feeling uncomfortable and rolling. By suppressing the backlash of the bearing, the service life of the rolling bearing can be extended.

  Further, a spring washer 56 that absorbs vibration urges the drive cylinder shaft 22 toward the tip side, so that the rolling bearing 24 a interposed between the drive cylinder shaft 22 and the rotor 28 has a simple structure. Although it is, it is possible to give an urging force without difficulty.

  4 and 5 show a modification. Since various modifications and embodiments described below are basically the same as the above-described embodiments, the same parts are denoted by the same reference numerals, and detailed description thereof is omitted.

  In the modification shown in FIG. 4, instead of the above-described spring washer 56, a coil spring 58 is inserted as an elastic member between the inner ring of the rolling bearing 24b and the pinion gear 22a to urge the drive cylinder shaft 22 toward the tip side. . In the modification shown in FIG. 5, the coil spring 60 is inserted between the outer ring of the rolling bearing 24b and the flange portion 17b of the receiving member 17, and the washer 62 is interposed between the inner ring of the rolling bearing 24b and the pinion gear 22a. It is inserted.

  In any of the modifications, as in the above-described embodiment, vibration caused by the rolling bearings 24a and 24b and the rotor 28 is prevented from being transmitted to the angler's hand through the reel body 12a, and the angler is uncomfortable. In addition, the service life of the rolling bearing can be extended by suppressing the backlash of the rolling bearing.

6 to 8 show a second embodiment.
In the fishing spinning reel 10A of this embodiment, unlike the gear system described above, the oscillating mechanism 32A meshes with the worm shaft (traverse cam shaft) 64a that meshes with the pinion gear 22a and the groove of the worm shaft 64a. The slider 64b is mounted so as not to move in the axial direction with respect to the spool shaft 30. When the handle shaft 18 is rotated by the rotation operation of the handle 16, the spool shaft 30 is reciprocated along the axial direction ( Back and forth).

  As shown in FIGS. 7 and 8 in an enlarged manner, the drive cylinder shaft 22 is in a state in which the axial movement is restricted by two rolling bearings 66a and 66b disposed before and after the one-way clutch 40, and the reel body 12a. Is supported rotatably. The rolling bearing 66a disposed in the front is formed in a sealed type in which the inside is sealed.

A washer 70 is interposed between the inner ring 40a of 40 and the inner ring of the front side rolling bearing 66a. Then, the rotor 28 is fixed onto the drive cylinder shaft 22 by tightening the nut 44 in a state where the rotor 28 is sandwiched between the front side rolling bearing 66a and the inner ring. A slight gap is provided between the outer ring of the rear side rolling bearing 66b and the outer ring of the one-way clutch 40 (see FIG. 8).

  Further, the outer ring of the front side rolling member 66a is in contact with the holding plate 54 at the front end side, and a spacer 72 is inserted between the outer ring 40c of the one-way clutch 40 and the outer ring of the front side rolling bearing 66a, and the front side rolling bearing. The outer ring of 66a and the outer ring of the one-way clutch 40 are restricted by the holding plate 54 from moving forward. Thus, the drive cylinder shaft 22 is held by the two rolling bearings 66a and 66b so as to be rotatable with respect to the reel body and restricted in the axial movement.

  In this embodiment, the O-ring 74 is inserted as an elastic member that urges the drive cylinder shaft 22 in the axial direction between the drive cylinder shaft 22 and the reel body 12a via the rear side rolling bearing 66b. Has been. Specifically, the O-ring 74 is inserted between the bottom wall of the concave ring portion 19 which is a support portion formed on the reel main body 12a or the outer ring of the stepped portion 19a and the rolling bearing 66b.

In order to restrict the movement of the inner ring in the axial direction, the respective outer rings are urged against the inner ring, and minute back-and-forth movement of the drive cylinder shaft 22 caused by rattling between the inner and outer rings of the rolling bearings 66a and 66b is absorbed.

  As described above, also in this embodiment, the O-ring 74 has a minute front-rear direction of the drive cylinder shaft 22 that occurs due to the backlash between the inner and outer rings of the rolling bearings 66a, 66b that restricts the axial movement of the drive cylinder shaft 22. The vibration of the rotor 28 generated by the movement of the rotor and the slight imbalance that occurs when the rotor 28 rotates is absorbed. This prevents vibrations from being transmitted to the angler via the reel body 12a, prevents the angler from feeling uncomfortable, and reduces the backlash of the rolling bearings 66a and 66b, thereby extending the service life of the rolling bearing. Can be extended.

  In each of the embodiments described above, the drive cylinder shaft 22 is supported by a plurality of rolling bearings that restrict axial movement, that is, the front side rolling bearings 24a and 66a and the rear side rolling bearings 24b and 66b, and the elastic member is Although it is arranged between the rear side rolling bearings 24b and 66b and the reel body 12a, the present invention is not limited to this, and it can be arranged between the front side rolling bearings 24a and 66a and the reel body 12a.
