Abstract
Description
Technical Field
[0001] This invention relates to a spinning reel. Background Technology
[0002] In spinning reels, various problems are known to occur at dead points during the reciprocating motion of the spool, specifically at the positions where the spool is positioned at the very front and the very back. For example, it is known that at these dead points, the fishing line comes into contact with each other during release, resulting in noise and increased resistance. Consequently, the flight distance decreases. Therefore, to solve this dead-point problem, techniques have been proposed that increase the spool diameter, extend the reciprocating stroke of the spool (e.g., see Patent Document 1), and reduce the winding spacing of the fishing line (e.g., see Patent Document 2).
[0003] Patent Document 1: Japanese Patent Application Publication No. 2019-106898.
[0004] Patent Document 2: Japanese Patent Application Publication No. 11-000086.
[0005] In the prior art, if the spool diameter is increased, the rotor used to wind the fishing line onto the spool also needs to be increased in diameter. Here, to ensure sufficient space for the rotor to rotate, the distance from the rod mounting foot to the housing needs to be increased. That is, the increased spool diameter leads to the problem of a larger spinning reel.
[0006] Furthermore, if the reciprocating stroke of the drum is extended, the length of the reciprocating mechanism in the front-to-back direction increases. Therefore, in order to accommodate this reciprocating mechanism, the housing portion needs to be enlarged. That is, due to the increase in the reciprocating stroke of the drum, the housing portion, i.e., the spinning reel, becomes larger.
[0007] On the other hand, compared with the aforementioned technologies, reducing the winding spacing of the fishing line is effective in preventing the increase in the size of spinning reels. However, the more the winding spacing of the fishing line is reduced, the more complex the structure becomes, such as a reduction gear mechanism with a large reduction ratio, and the more difficult-to-manufacture parts are required, such as a worm shaft with thin walls between the slots. In other words, this leads to the problem of the spinning reel's structure becoming more complex and its manufacturing cost increasing.
[0008] For example, as a way to construct a reduction mechanism with a large reduction ratio using a simple gear train, it is advisable to consider using gears with a small module. However, when using gears with a small module, the strength of the gears needs to be considered during the design process. Therefore, in order to design appropriate gears that correspond to the thickness of the fishing line and the size of the spool, multiple trials and complex strength calculations are required.
[0009] Thus, existing technologies for solving the dead point problem have a variety of problems as described above.
[0010] Therefore, this invention proposes a basic structure useful for designing reciprocating mechanisms and drums. Specifically, this invention sets reference values for designing reciprocating mechanisms and drums, and designs the reciprocating mechanisms and drums using these reference values. Summary of the Invention
[0011] The purpose of this invention is to provide a spinning winding wheel that has a basic structure that can appropriately solve the problems of conventional spinning winding wheels.
[0012] One embodiment of the present invention provides a spinning reel comprising a spool shaft, a drum, a planetary gear, a reciprocating mechanism, and an intermediate gear. The spool shaft is supported movably relative to the reel body in a front-to-back direction. The drum is connected to the spool shaft. Fishing line is wound onto the drum. The planetary gear is rotatably supported on the reel body. The reciprocating mechanism causes the spool shaft to reciprocate in a front-to-back direction.
[0013] The intermediate gear is positioned between the planetary gear and the reciprocating mechanism. The intermediate gear reduces the rotational speed of the planetary gear and transmits this speed to the reciprocating mechanism. The stroke of the spool shaft divided by the winding spacing of the fishing line and the module of the intermediate gear must be 60 or higher.
[0014] This spinning reel is configured such that the stroke of the drum shaft divided by the winding spacing of the fishing line and the module of the intermediate gear is 60 or more. By utilizing this structure in the design of the reciprocating movement mechanism and drum, the problems inherent in conventional spinning reels can be appropriately resolved.
[0015] In other embodiments of the present invention, the spinning reel preferably has a stroke of the spool divided by the winding spacing of the fishing line and the module of the intermediate gear of 150 or less.
[0016] In other embodiments of the present invention, the spinning winding reel preferably has a winding spacing of 1.0 mm or less.
[0017] In other embodiments of the spinning reel of the present invention, preferably, the reel has a line winding body on which the fishing line is wound around its outer periphery, and a front flange extending radially outward from the front end of the line winding body. In this case, the outer diameter of the front flange is less than 60 mm.
[0018] In other embodiments of the present invention, the spinning winding reel preferably has a first intermediate gear and a second intermediate gear. The smaller of the module of the first intermediate gear and the module of the second intermediate gear is selected as the module of the intermediate gear.
[0019] The first intermediate gear is configured to rotate about a first axis parallel to the drum shaft. The first intermediate gear has a first major diameter gear that meshes with the planetary gear and a first minor diameter gear that has a smaller diameter than the first major diameter gear and rotates integrally with the first major diameter gear.
[0020] The second intermediate gear is configured to rotate about a second axis parallel to the first axis. The second intermediate gear has a second major diameter gear that meshes with the first minor diameter gear, and a second minor diameter gear with a smaller diameter than the second major diameter gear that rotates integrally with the second major diameter gear. The reciprocating mechanism has a driven gear that meshes with the second minor diameter gear, and a worm shaft that rotates integrally with the driven gear.
[0021] This structure allows the fishing line to be wound onto the spool while slowing down the forward and backward movement of the spool shaft. Therefore, it can effectively solve the problems of conventional spinning reels with a relatively simple construction.

[0031] The spinning type winding wheel 1 according to one embodiment of the present invention is as follows: Figure 1 As shown, it comprises a winding reel body 3, a handle 5, a drum 7, and a rotor 9. Figure 2As shown, the spinning reel 1 also includes a handle shaft 11, a drive gear 13, a drum shaft 15, a planetary gear 17, a reduction mechanism 19, and an oscillation mechanism 21 (an example of a reciprocating mechanism). Furthermore, Figure 2 It means Figure 1 The figure shows the side cover 1a and main protective component 1b of the spinning type winding wheel 1 being removed.
[0032] like Figure 1 As shown, the handle 5 is rotatably supported on the winding reel body 3. In this embodiment, an example is shown where the handle 5 is positioned on the left side of the winding reel body 3. The handle 5 may also be positioned on the right side of the winding reel body 3. The handle 5 is mounted on the handle shaft 11.
[0033] like Figure 2 As shown, the handle shaft 11 is rotatably supported on the winding reel body 3. The drive gear 13 is mounted on the handle shaft 11 in a manner that allows it to rotate integrally with the handle shaft 11. The drive gear 13 meshes with the planetary gear 17.
[0034] The fishing line is wound around the reel 7. (Example) Figure 2 As shown, the drum 7 is configured to move along the front-to-back direction relative to the winding reel body 3 together with the drum shaft 15. The drum 7 is connected to the drum shaft 15. For example, the drum 7 is connected to the end of the drum shaft 15 via a traction mechanism not shown in the figure.
[0035] The drum 7 has a central axis X2. When the drum 7 is connected to the drum shaft 15, the central axis X2 of the drum 7 is coaxial with the drum shaft X1 described later.
[0036] like Figure 3 As shown, the spool 7 has a line winding body 7a, a front flange 7b, and a skirt 7c. Fishing line is wound around the outer periphery of the line winding body 7a. The line winding body 7a is formed in a cylindrical shape. The front flange 7b extends radially outward from the front end of the line winding body 7a. The front flange 7b is integrally formed with the line winding body 7a. The front flange 7b is formed in a circular plate shape. The front flange 7b has an outer diameter R. The outer diameter R of the front flange 7b is defined by the outer peripheral surface 7b1 of the front flange 7b. A spool collar 10 is disposed radially outward from the front flange 7b (see reference). Figure 2 The spool collar 10 covers the outer peripheral surface 7b1 of the front flange 7b.
[0037] The skirt portion 7c is integrally formed with the rear end of the main body portion 7a. The skirt portion 7c has a rear flange 7c1 and a tubular portion 7c2. The rear flange 7c1 extends radially outward from the rear end of the main body portion 7a. The rear flange 7c1 is integrally formed with the main body portion 7a. The rear flange 7c1 is formed in a circular plate shape. The tubular portion 7c2 extends rearward from the outer periphery of the rear flange 7c1. The tubular portion 7c2 is integrally formed with the rear flange 7c1. The tubular portion 7c2 is formed in a tubular shape.
[0038] like Figure 2 As shown, the spool 15 is supported in a way that allows it to move in the front-to-back direction relative to the winding reel body 3. The spool 15 is inserted into the inner circumference of the cylindrical planetary gear 17. The spool 15 moves in the front-to-back direction relative to the winding reel body 3 through the operation of the oscillation mechanism 21.
[0039] The drum shaft 15 has a drum axis X1. The front-to-back direction and axial direction are the directions in which the drum axis X1 extends. The radial direction is the direction away from the drum axis X1. The circumferential direction and rotational direction are the directions about the drum axis X1.
[0040] The oscillation mechanism 21 moves the spool shaft 15 in the back-and-forth direction. The oscillation mechanism 21 moves the spool shaft 15 in the back-and-forth direction, for example, in conjunction with the rotation of the handle shaft 11. The oscillation mechanism 21 is disposed within the internal space of the winding reel body 3.
[0041] like Figure 2 and Figure 4 As shown, the oscillation mechanism 21 includes a worm shaft 23, a slider 25, and a worm shaft gear 27 (an example of a driven gear). The worm shaft 23 rotates to allow the drum shaft 15 and the slider 25 to move in the back-and-forth direction. The worm shaft 23 is arranged parallel to the drum shaft 15. The worm shaft 23 is rotatably supported on the winding reel body 3. The worm shaft 23 has a rotation axis W1.
[0042] The worm shaft 23 has a shaft body 23a and a groove 23b. The shaft body 23a is a shaft component that is longer in one direction. The shaft body 23a extends axially along the rotation axis W1. The groove 23b is provided on the outer peripheral surface of the shaft body 23a. The pawl component 26, described later, engages with the groove 23b.
[0043] The slider 25 is mounted on the drum shaft 15. For example, the slider 25 is fixed to the rear end of the drum shaft 15. The slider 25 moves in the back-and-forth direction by the rotation of the worm shaft 23.
[0044] For example, such as Figure 4As shown, the claw component 26 is mounted on the slider 25. The claw component 26 is rotatably mounted on the drum shaft 15 and the slider 25. The claw component 26 engages with the groove 23b of the worm shaft 23. Thus, when the worm shaft 23 rotates, the claw component 26 moves along the groove 23b of the worm shaft 23. As a result, the slider 25 moves in the back-and-forth direction.
[0045] like Figure 2 and Figure 4 As shown, the worm shaft gear 27 is mounted on the worm shaft 23. For example, the worm shaft gear 27 has a rotation axis W2. The worm shaft gear 27 is mounted on the worm shaft 23 in such a way that the rotation axis W2 of the worm shaft gear 27 is concentric with the rotation axis W1 of the worm shaft 23. The worm shaft gear 27 and the worm shaft 23 rotate integrally.
[0046] like Figure 4 As shown, the worm gear 27 has a gear body 27a and a through hole 27b. The gear body 27a is formed in the shape of a circular plate. The gear body 27a meshes with the second minor diameter gear 33b (described later) of the reduction mechanism 19.
[0047] A through hole 27b is provided in the gear body 27a. For example, the through hole 27b passes through the gear body 27a in the axial direction extending from the rotation axis W2 of the worm shaft gear 27. The worm shaft 23 is inserted into the through hole 27b. In this state, the worm shaft 23 rotates integrally with the worm shaft gear 27.
[0048] like Figure 2 As shown, the planetary gear 17 is cylindrical. The planetary gear 17 is rotatably supported on the winding reel body 3. The planetary gear 17 is disposed radially outward of the spool shaft 15. The planetary gear 17 rotates relative to the spool shaft 15. The planetary gear 17 rotates about the spool axis X1.
[0049] like Figure 5 As shown, the reduction mechanism 19 reduces the rotation of the planetary gear 17 and transmits it to the oscillation mechanism 21. Figure 5 In the diagram, the gear teeth of each gear are omitted. Shaded lines are drawn around the meshing parts of the gears.
[0050] The reduction mechanism 19 is disposed between the planetary gear 17 and the oscillation mechanism 21. For example, the reduction mechanism 19 is disposed between the planetary gear 17 and the worm shaft gear 27. The reduction mechanism 19 has a first intermediate gear 31 and a second intermediate gear 33.
[0051] The first intermediate gear 31 is configured to rotate about a first axis A1 parallel to the spool axis X1. The first intermediate gear 31 is rotatably supported on the winding reel body 3. The first intermediate gear 31 has a first module M1. The first module M1 is calculated by dividing the diameter d1 of the pitch circle of the first intermediate gear 31 by the number of teeth z1 of the first intermediate gear 31. This calculation formula is expressed as "M1 = d1 / z1". Figure 5 In the diagram, the leader line representing the number of teeth z1 of the first intermediate gear 31 is represented by a double-dotted dashed line.
[0052] The first intermediate gear 31 has a first major diameter gear 31a and a first minor diameter gear 31b. The first major diameter gear 31a meshes with the planetary gear 17. The axis of rotation of the first major diameter gear 31a is the first shaft A1. The first minor diameter gear 31b is formed with a diameter smaller than that of the first major diameter gear 31a. The first minor diameter gear 31b is integrally formed with the first major diameter gear 31a and rotates integrally with the first major diameter gear 31a. The axis of rotation of the first minor diameter gear 31b is the first shaft A1.
[0053] The second intermediate gear 33 is configured to rotate about a second axis A2 parallel to the first axis A1. The second intermediate gear 33 is rotatably supported on the winding reel body 3. The second intermediate gear 33 has a second module M2. The second module M2 is calculated by dividing the diameter d2 of the pitch circle of the second intermediate gear 33 by the number of teeth z2 of the second intermediate gear 33. This calculation formula is expressed as "M2 = d2 / z2". Figure 5 In the diagram, the leader line representing the number of teeth z2 of the second intermediate gear 33 is represented by a double-dotted dashed line.
[0054] The second intermediate gear 33 has a second major diameter gear 33a and a second minor diameter gear 33b. The second major diameter gear 33a meshes with the first minor diameter gear 31b. The rotation axis of the second major diameter gear 33a is the second shaft A2. The second minor diameter gear 33b is formed with a diameter smaller than that of the second major diameter gear 33a. The second minor diameter gear 33b is integrally formed with the second major diameter gear 33a and rotates integrally with the second major diameter gear 33a. The rotation axis of the second minor diameter gear 33b is the second shaft A2. The second minor diameter gear 33b meshes with the worm gear shaft 27.
[0055] If the handle shaft 11 rotates due to the rotation of the handle 5, the drive gear 13 rotates. The rotation of the drive gear 13 is transmitted to the planetary gear 17. The rotation of the planetary gear 17 is transmitted to the worm shaft gear 27 via the aforementioned reduction mechanism 19. The rotation of the worm shaft gear 27 is transmitted to the worm shaft 23. Due to the rotation of the worm shaft 23, the slider 25 and the drum shaft 15 move in the back-and-forth direction.
[0056] like Figure 1 and Figure 2As shown, rotor 9 is used to wind fishing line onto spool 7. Rotor 9 is located at the front of reel body 3. Rotor 9 is configured to rotate relative to reel body 3. Rotor 9 is located radially outward of planetary gear 17. Rotor 9 is assembled to rotate integrally with respect to planetary gear 17.
[0057] If the handle shaft 11 rotates due to the rotation of the handle 5, the drive gear 13 rotates. The rotation of the drive gear 13 is transmitted to the planetary gear 17. The rotor 9 rotates in conjunction with the rotation of the planetary gear 17.
[0058] The spinning type winding wheel 1 having the above structure is configured as follows. Figure 3 and Figure 6 The outer diameter R of the front flange 7b shown is less than 60 mm. For example, the outer diameter R of the front flange 7b is preferably 35 mm or more and less than 60 mm. More preferably, the outer diameter R of the front flange 7b is 40 mm or more and less than 56 mm. The outer diameter R of the front flange 7b is defined by the outer peripheral surface 7b1 of the front flange 7b.
[0059] The winding spacing P of the fishing line is 1.0 mm or less. For example, the winding spacing P of the fishing line is preferably 0.4 mm or more and 1.0 mm or less. More preferably, the winding spacing P of the fishing line is 0.55 mm or more and 0.90 mm or less. The winding spacing P of the fishing line is the axial spacing between adjacent fishing lines on the line winding body 7a.
[0060] Furthermore, the winding pitch P is not constant depending on the construction of the oscillation mechanism 21. Therefore, the average winding pitch is used as the winding pitch P here. The average winding pitch is the value of the reciprocating stroke distance (2S) divided by the number of times the rotor 9 rotates (N) during one reciprocating motion of the drum 7 (2S / N).
[0061] The value (S / (P・M)) obtained by dividing the stroke S of the reel shaft 15 by the smaller of the winding pitch P of the fishing line and the first module M1 of the first intermediate gear 31 and the second module M2 of the second intermediate gear 33 is 60 or more. The value (S / (P・M)) obtained by dividing the stroke S of the reel shaft 15 by the smaller of the winding pitch P of the fishing line and the first module M1 of the first intermediate gear 31 and the second module M2 of the second intermediate gear 33 is 150 or less. These relationships are expressed by the formula "60≤(S / (P・M))≤150".
[0062] like Figure 6 As shown, the stroke S of the drum shaft 15 is the amount by which the drum shaft 15 moves in the forward and backward direction by means of the oscillation mechanism 21. The stroke S of the drum shaft 15 is preferably 12 mm or more and 25 mm or less. More preferably, the stroke S of the drum shaft 15 is 13 mm or more and 23 mm or less.
[0063] Figure 7 Therefore, the above-mentioned values and the comprehensive evaluation of casting and winding are presented in the table among the spinning winding wheel 1 using the present invention (models 1 and 2), the spinning winding wheel 1 using the present invention by changing the specifications of models 1 and 2 (comparative model 3), and conventional spinning winding wheels (conventional models 1 to 3) having an intermediate gear or a gear equivalent to an intermediate gear.
[0064] Figure 7 The "Comprehensive Evaluation of Casting and Reeling" will be conducted by multiple testers using a paired comparative test method to evaluate the quietness, stretch, and winding stability of each spinning reel in "size type A, B, and C" during casting and reeling, and to rank them. In addition, the letters in the "Comprehensive Evaluation of Casting and Reeling" symbol indicate the size type, and the numbers indicate the evaluation order.
[0065] For example, in size type A, the overall evaluation A1 using model 1 is higher than the overall evaluation A2 of the previous model 1. In size type B, the overall evaluation B1 using model 2 is higher than the overall evaluation B2 of the previous model 2. In size type C, the overall evaluation C1 of the comparative model 3 is higher than the overall evaluation C2 of the previous model 3. Thus, the overall evaluations A1, B1, and C1 of using model 1, using model 2, and comparing model 3 all receive high evaluations compared to the overall evaluations A2, B2, and C2 of the previous models in each size type A, B, and C.
[0066] The aforementioned spinning reel 1 has the following characteristics. The spinning reel 1 is configured such that the stroke S of the drum shaft 15 divided by the winding spacing P of the fishing line and the module M of the intermediate gears 31 and 33 (S / (P・M)) is 60 or more. By utilizing this structure in the design of the oscillation mechanism 21 and the drum 7, the problems inherent in conventional spinning reels can be appropriately solved.
[0067] In the spinning reel 1, the stroke S of the spool shaft 15 divided by the winding pitch P of the fishing line and the module M of the intermediate gears 31 and 33 (S / (P・M)) is 150 or less. In the spinning reel 1, the winding pitch P is 1.0 mm or less. The outer diameter R of the front flange 7b in the spinning reel 1 is less than 60 mm. The spinning reel 1 has a first intermediate gear 31 and a second intermediate gear 33, so that the fishing line can be wound onto the line winding body 7a while the spool shaft 15 is decelerated in the forward and backward direction. Therefore, the problems of conventional spinning reels can be appropriately solved with a relatively simple structure.
