Description

[Technical Field]

[0001] This invention relates to a color component for a spinning reel. [Background technology]

[0002] Conventional spinning reels include a reel body, a spool shaft, a pinion gear, a rotor, a rotor nut, a metal or resin collar component, and a bearing (see Patent Document 1).

[0003] The rotor nut is positioned on the pinion gear at the front of the pinion gear. The rotor nut restricts the forward movement of the rotor relative to the pinion gear. The rotor nut rotates integrally with the pinion gear.

[0004] Generally, the collar member is formed in a cylindrical shape. The collar member is positioned on the spool shaft in front of the pinion gear. The bearing is positioned radially on the collar member. The bearing is positioned radially between the collar member and the rotor nut, and rotatably supports the rotor nut relative to the spool shaft. [Prior art documents] [Patent Documents]

[0005] [Patent Document 1] Japanese Patent Publication No. 2016-029949 [Overview of the project] [Problems that the invention aims to solve]

[0006] In the conventional spinning reel described above, when the spool shaft moves in the forward and backward direction relative to the reel body, the outer surface of the spool shaft slides against the inner surface of the collar member.

[0007] For example, if the collar component is made of metal such as brass, it is difficult to precisely and smoothly machine the inner surface roughness of a thin-walled collar component. If the collar component is made thicker to achieve precise machining, it leads to an increase in the diameter and weight of the collar component itself and the bearing. If the collar component is made of resin, this problem can be solved.

[0008] However, when resins such as polyacetal, which are commonly used for sliding members, are used for collar members, the coefficient of linear expansion of the collar member increases. As a result, at low or high temperatures, the contraction or expansion of the inner and outer diameters of the collar member may increase sliding resistance and looseness, potentially leading to unstable sliding feel.

[0009] The present invention has been made in view of the above problems, and the object of the present invention is to provide a collar member for a spinning reel that can stabilize the sliding feeling when the spool shaft moves in the front-rear direction. [Means for solving the problem]

[0010] A collar member for a spinning reel according to one aspect of the present invention is used in a spinning reel. A spinning reel has a spool shaft that moves in the front-rear direction relative to the reel body, a pinion gear that rotates around the spool shaft, a rotor nut that rotates integrally with the pinion gear, and a bearing that is positioned radially between the spool shaft and the rotor nut and rotatably supports the rotor nut. In this spinning reel, the collar member is positioned radially between the spool shaft and the bearing. The collar member is formed from a resin material. The resin material is 10 × 10 -6 (1 / ℃) or higher and 50 × 10 -6 It has a linear expansion coefficient of (1 / °C) or less.

[0011] Since the collar member of the spinning reel of the present invention is formed from a resin material, the surface roughness of the inner circumferential surface of the collar member can be easily adjusted, and the collar member can be made smaller and lighter.

[0012] Furthermore, the color components of this spinning reel are made of resin material that is 10 x 10 -6 (1 / ℃) or higher and 50 × 10 -6 Because it has a coefficient of linear expansion of 1 / °C or less, it can reduce sliding resistance and rattle at both low and high temperatures. In other words, it can stabilize the sliding feeling when the spool shaft moves in the front-to-back direction.

[0013] In another aspect of the present invention, the color member of a spinning reel preferably contains carbon in the resin material. This configuration allows for further weight reduction of the color member, in addition to the effects described above.

[0014] In the color member of a spinning reel according to another aspect of the present invention, the carbon is preferably carbon fiber. This configuration can improve the strength of the color member.

[0015] In another aspect of the present invention, the color member of a spinning reel preferably contains 10 to 25 percent by weight of carbon fiber in the resin material. This configuration allows for a favorable improvement in the strength of the color member.

[0016] A spinning reel according to another aspect of the present invention comprises a reel body, a spool shaft, a pinion gear, a rotor, a rotor nut, a bearing, and a collar member. The spool shaft is supported so as to be movable in the front-rear direction relative to the reel body. The pinion gear is located radially outward from the spool shaft and rotates relative to the spool shaft. The rotor is located radially outward from the pinion gear and rotates integrally with the pinion gear.

[0017] The rotor nut restricts the forward movement of the rotor relative to the pinion gear. The rotor nut rotates integrally with the pinion gear. The bearing is positioned radially between the spool shaft and the rotor nut. The bearing rotatably supports the rotor nut relative to the spool shaft.

[0018] The color member is disposed between the spool shaft and the bearing in the radial direction. The color member is formed of a resin material. The resin material has a linear expansion coefficient of 10×10 -6 (1 / °C) or more and 50×10 -6 (1 / °C) or less. By configuring the color member in this way, the spinning reel can obtain the same effect as described above.

Advantages of the Invention

[0019] In the present invention, in the color member of the spinning reel, the sliding feeling when the spool shaft moves in the front-rear direction can be stabilized.

Mode for Carrying Out the Invention

[0021] As shown in FIG. 1, a spinning reel 1 employing an embodiment of the present invention includes a reel body 3, a handle 5, a spool 7, and a rotor 9. As shown in FIG. 2, the spinning reel 1 further includes a handle shaft 11, a drive gear 13, a spool shaft 15, an oscillating mechanism 17, a pinion gear 19, a rotor nut 21, a bearing 23, and a color member 25. The spinning reel 1 further includes a seal member 27 and a holding member 29.

[0022] As shown in FIG. 1, the handle 5 is rotatably supported by the reel body 3. In the present embodiment, an example in which the handle 5 is disposed on the left side of the reel body 3 is shown. The handle 5 may be disposed on the right side of the reel body 3. The handle 5 is attached to the handle shaft 11.

[0023] As shown in Figure 2, the handle shaft 11 is rotatably supported by the reel body 3. The drive gear 13 is mounted on the handle shaft 11 so as to be able to rotate integrally with the handle shaft 11. The drive gear 13 meshes with the pinion gear 19.

[0024] As shown in Figure 1, fishing line is wound around the spool 7. The spool 7 is configured to move in the front-to-back direction relative to the reel body 3 together with the spool shaft 15. The spool 7 is attached to the tip of the spool shaft 15.

[0025] As shown in Figure 2, the spool shaft 15 is supported so as to be movable in the front-rear direction relative to the reel body 3. The spool shaft 15 is inserted into the inner circumference of the cylindrical pinion gear 19. The spool shaft 15 reciprocates in the front-rear direction relative to the reel body 3 by the operation of the oscillating mechanism 17.

[0026] The spool shaft 15 has a spool axis X1. The front-rear and axial directions are the directions in which the spool axis X1 extends. The radial direction is the direction away from the spool axis X1. The circumferential and rotational directions are the directions around the spool axis X1.

[0027] The oscillating mechanism 17 moves the spool shaft 15 in the forward and backward directions in conjunction with the rotation of the handle shaft 11. The oscillating mechanism 17 is located in the internal space of the reel body 3. The oscillating mechanism 17 includes a worm shaft 17a, a slider 17b, and an intermediate gear 17c. The worm shaft 17a is positioned parallel to the spool shaft 15. The worm shaft 17a is rotatably supported by the reel body 3.

[0028] The slider 17b is fixed to the rear end of the spool shaft 15. The slider 17b engages with a groove in the worm shaft 17a and moves in the forward and backward direction as the worm shaft 17a rotates. The intermediate gear 17c is fixed to the tip of the worm shaft 17a and engages with the pinion gear 19.

[0029] In the oscillating mechanism 17, when the handle shaft 11 rotates due to the rotation of the handle 5, the drive gear 13, pinion gear 19, intermediate gear 17c, and worm shaft 17a rotate. As a result, the slider 17b and spool shaft 15 move in the forward and backward directions.

[0030] The rotor 9 is used to wind the fishing line onto the spool 7. The rotor 9 is located at the front of the reel body 3. The rotor 9 is configured to be rotatable relative to the reel body 3. The rotor 9 is located radially outward of the pinion gear 19. The rotor 9 is mounted integrally with the pinion gear 19 so as to be rotatable.

[0031] The pinion gear 19 is formed in a cylindrical shape. The pinion gear 19 is rotatably supported by the reel body 3. The pinion gear 19 is positioned radially outward from the spool shaft 15. The pinion gear 19 rotates relative to the spool shaft 15. For example, the pinion gear 19 rotates around the spool axis X1. The rotor 9 rotates in conjunction with the rotation of the pinion gear 19.

[0032] The rotor nut 21 is used to restrict the forward movement of the rotor 9 relative to the pinion gear 19. The rotor nut 21 rotates relative to the spool shaft 15. For example, the rotor nut 21 rotates around the spool axis X1.

[0033] As shown in Figure 3, the rotor nut 21 has a cylindrical portion 21a and a mounting portion 21b. The cylindrical portion 21a is formed in a cylindrical shape. The cylindrical portion 21a is formed integrally with the mounting portion 21b. The cylindrical portion 21a is formed to have a larger diameter than the mounting portion 21b. The cylindrical portion 21a extends forward from the mounting portion 21b and is positioned in front of the front end of the pinion gear 19. A bearing 23 and a collar member 25 are positioned radially between the cylindrical portion 21a and the spool shaft 15.

[0034] The mounting portion 21b is fixed to the front end of the pinion gear 19. For example, the mounting portion 21b is screwed onto the front end of the pinion gear 19. This causes the rotor nut 21 to rotate integrally with the pinion gear 19. The mounting portion 21b also contacts the radially inner portion 9a of the rotor 9, for example, the portion 9a where the rotor 9 is mounted on the pinion gear 19. This causes the rotor nut 21 to restrict the forward movement of the rotor 9 relative to the pinion gear 19.

[0035] The rearward movement of the rotor 9 relative to the pinion gear 19 is restricted by the bearing 31 and the cylindrical member 32. The bearing 31 is positioned between the pinion gear 19 and the reel body 3. The outer ring of the bearing 31 is mounted on the reel body 3. The inner ring of the bearing 31 is positioned on the outer circumferential surface of the pinion gear 19. The cylindrical member 32 is positioned axially between the bearing 31 and the rotor 9. More specifically, the cylindrical member 32 is positioned axially between the bearing 31 and the radially inner portion 9a of the rotor 9.

[0036] The bearing 23 rotatably supports the rotor nut 21 relative to the spool shaft 15. For example, the bearing 23 rotatably supports the rotor nut 21 relative to the spool shaft 15 via a collar member 25.

[0037] The bearing 23 is positioned radially between the spool shaft 15 and the rotor nut 21. More specifically, the bearing 23 is positioned in front of the pinion gear 19. The outer ring of the bearing 23 is integrally rotatably mounted with respect to the inner circumferential surface of the rotor nut 21, for example, the inner circumferential surface of the cylindrical portion 21a. The inner ring of the bearing 23 is positioned on the outer circumferential surface of the collar member 25. Rolling elements are positioned between the outer and inner rings of the bearing 23.

[0038] The sealing member 27 is formed in an annular shape. The sealing member 27 is mounted on the rotor nut 21. For example, the sealing member 27 is mounted on the open end of the cylindrical portion 21a of the rotor nut 21. As a result, the sealing member 27 covers the front end of the bearing 23. The inner circumference end of the sealing member 27 contacts the spool shaft 15.

[0039] The holding member 29 holds the seal member 27. The holding member 29 is attached to the rotor nut 21. The holding member 29 positions the seal member 27 with respect to the rotor nut 21. For example, the seal member 27 is axially sandwiched by the holding member 29 and the open end of the cylindrical portion 21a of the rotor nut 21.

[0040] The collar member 25 is formed in a cylindrical shape. The collar member 25 is disposed between the spool shaft 15 and the bearing 23 in the radial direction. For example, the collar member 25 is disposed between the outer peripheral surface of the spool shaft 15 and the inner ring of the bearing 23 in the radial direction.

[0041] The spool shaft 15 is inserted through the inner peripheral portion of the collar member 25. A minute gap is formed between the inner peripheral surface of the collar member 25 and the outer peripheral surface of the spool shaft 15. In this state, the spool shaft 15 moves back and forth in the inner peripheral portion of the collar member 25.

[0042] The collar member 25 is formed of a resin material. The resin material contains carbon. The resin material may further contain polyacetal. For example, the carbon is carbon fiber. The carbon fiber is 10 to 25 weight percent of the resin material. Note that the carbon may contain granular carbon instead of fibrous carbon. Also, the carbon may contain both fibrous carbon and granular carbon.

[0043] The resin material has a linear expansion coefficient of 10×10 -6 (1 / °C) or more and 50×10 -6 (1 / °C) or less. For example, when the temperature is 23 (°C) or more and 55 (°C) or less, the average value of the linear expansion coefficient is 10×10 -6 (1 / °C) or more and 50×10 -6 (1 / °C) or less. The resin material has a coefficient of dynamic friction of 0.15 or more and 0.40 or less. The coefficient of dynamic friction is used to define the surface roughness of the inner peripheral surface of the collar member 25.

[0044] The spinning reel 1 described above has the following features. In the spinning reel 1, the collar member 25 is made of a resin material, so the surface roughness of the inner circumferential surface of the collar member 25 can be easily adjusted. This improves the sliding feel when the spool shaft 15 slides against the inner circumferential surface of the collar member 25.

[0045] Furthermore, if the surface roughness of the inner circumferential surface of the collar member 25 is adjusted, and the radial gap between the collar member 25 and the spool shaft 15 is designed to be small in order to reduce the play of the spool shaft 15 relative to the collar member 25, the gap may change due to temperature changes, potentially reducing the sliding feel. However, in the spinning reel 1, the resin material is 10 × 10 -6 (1 / ℃) or higher and 50 × 10 -6 Since it has a linear expansion coefficient of (1 / °C) or less, this can suppress the deterioration of the sliding feel.

[0046] Thus, in the spinning reel 1, the color member 25 is formed from a resin material, and the coefficient of linear expansion of the resin material is 10 × 10 -6 (1 / ℃) or higher and 50 × 10 -6 By setting it to (1 / °C) or lower, the sliding feeling when the spool shaft 15 moves in the front-to-back direction can be stabilized.

[0047] Furthermore, in spinning reel 1, since the resin material contains carbon, the color component 25 can be made lighter. Also, since the carbon is carbon fiber, the strength of the color component 25 can be improved. If the carbon is granular carbon rather than fibrous carbon, the orientation of shrinkage during injection molding can be suppressed, and the color component can be molded with high precision. In addition, since the carbon fiber is 10 to 25 weight percent of the resin material, the strength of the color component 25 can be suitably improved. [Industrial applicability]
