AI Technical Summary
Existing electric fishing reels face issues such as shortened product life, noise, decreased winding efficiency, and increased manufacturing costs due to low coaxiality between the motor shaft and one-way clutch shaft, and enlarged bearings when the one-way clutch's outer diameter is increased.
The electric reel design allows for rotation transmission from the motor to the one-way clutch regardless of coaxiality by using a motor shaft fixing member and a one-way clutch shaft member with a predetermined backlash, reducing the one-way clutch's outer diameter and minimizing bearing size.
This design extends the product life, reduces costs, and maintains efficient winding performance by ensuring rotation transmission despite misalignment, while allowing for a smaller one-way clutch and bearings.

DETAILED DESCRIPTION OF THE INVENTION
[0014] Hereinafter, an embodiment of an electric reel according to the present invention will be described in detail with reference to the accompanying drawings. Components common to multiple drawings are designated by the same reference numerals throughout the multiple drawings. Please note that the drawings are not necessarily drawn to scale for the sake of convenience.
[0015] First, the basic configuration of an electric reel (electric fishing reel) 1 according to one embodiment of the present invention will be described with reference to Figure 1. As shown in the figure, the electric reel 1 winds fishing line onto a spool 2, switches between a state in which the fishing line can be released from the spool 2 and a state in which the fishing line cannot be released, causes the spool 2 to spin freely (drag function) when tension above a set value is applied to the fishing line, and can also set a threshold tension and adjust the braking force to prevent backlash when the rig is dropped or cast.
[0016] As shown in FIG. 1, the electric reel 1 includes a reel body 10 having left and right frames 3a, 3b spaced apart from each other and side plates 4a, 4b covering the left and right frames 3a, 3b. A spool 2, a motor (electric motor) 5, a reduction gear mechanism 6, and a fishing information device (control case with a display unit) 7 are mounted between the left and right frames 3a, 3b. A handle shaft 8 is rotatably supported by the right frame 3b and the right side plate 4b, and a handle (operating unit) 9 is attached to its end. The left and right frames 3a, 3b are not limited to a cage-type structure. In other words, the left frame 3a and the right frame 3b of the left and right frames 3a, 3b may be formed separately, or they may be formed integrally.
[0017] The left and right frames 3a, 3b are the framework of the reel body 10 and are made of metal materials such as, but not limited to, aluminum alloy, magnesium alloy, etc. The left and right frames 3a, 3b are integrated via a plurality of support columns (not shown). A cylindrical front frame is provided at the front of the left and right frames 3a, 3b and is made of, but not limited to, metal materials such as, but not limited to, aluminum alloy, magnesium alloy, etc. Front Frame of A motor 5 and a reduction mechanism 6 are housed inside.
[0018] The spool 2 is driven to rotate in the fishing line winding direction by the rotational drive of the motor 5 via a speed reduction mechanism 6 and the like. right Frame 3 b The speed reducer mechanism 6 is provided on the right side of the motor 5 and reduces the output of the motor 5. As shown in FIG. 1, the speed reducer mechanism 6 also includes a planetary gear mechanism 12 that is installed between the drive shaft (motor shaft) 11 of the motor 5 and the right frame 3b.
[0019] Here, planetary gear mechanism 12 is made up of a sun gear, internal teeth, and multiple planetary gears. The sun gear is fixed to the tip of drive shaft (motor shaft) 11 of motor 5 so as to prevent rotation, and rotates integrally with drive shaft (motor shaft) 11.
[0020] A one-way clutch 16 is attached to the shaft end of the input shaft (shaft member for one-way clutch) 15. The one-way clutch 16 has the function of transmitting the rotation of the input shaft 15 in one direction to the output shaft. The one-way clutch 16 is disposed between the outer peripheral surface of the shaft end of the input shaft 15 and the inner peripheral surface of the cylindrical portion of the output shaft 17.
[0021] The output shaft is preferably arranged coaxially with the input shaft (shaft member for one-way clutch) 15 and the drive shaft 11. The output shaft has a cylindrical portion, which covers the shaft end of the input shaft 15 from the outer periphery, and the driving force from the input shaft 15 is input via the one-way clutch 16.
[0022] Next, an electric reel 1 according to one embodiment of the present invention will be further described with reference to Figures 2 to 7. As shown in these figures, the electric reel 1 according to one embodiment of the present invention is an electric reel 1 comprising a spool 2 for winding fishing line, a motor 5 having a motor shaft 11 and driven to rotate the spool 2, and a one-way clutch 16 for preventing reverse rotation of the motor 5, a motor shaft fixing member 20 fixed to the motor shaft 11, a one-way clutch shaft member 15 fitted to the one-way clutch 16, and the rotation of the motor 5 is transmitted to the one-way clutch 16 via the motor shaft fixing member 20 and the one-way clutch shaft member 15. Furthermore, in the electric reel 1 according to one embodiment of the present invention, the motor shaft fixing member 20 and the one-way clutch shaft member 15The term "rotational force transmission" refers to a torque transmission mechanism that transmits rotation with a predetermined amount of backlash. Here, "allowing a predetermined amount of backlash" refers to intentionally providing a gap in the direction of rotation (motion). In this case, "predetermined backlash" refers to a degree of backlash that transmits rotation to the output side while the input side (input shaft) rotates at least once (360°). That is, the degree of rotation transmission to the output side refers to the output side rotating in the same direction as the input side within a range of less than one rotation (by absorbing backlash) while the input side rotates once. On the other hand, if the output side does not rotate due to the force received during one rotation of the input side, this does not qualify as "predetermined backlash" as used herein. Furthermore, in comparison with an "Oldham coupling," an "Oldham coupling" can transmit rotation even when the axes are not aligned, but the two axes must be parallel. In contrast to this, in the electric reel 1 according to one embodiment of the present invention, the rotation of the motor 5 is transmitted to the one-way clutch 16 via the motor shaft fixing member 20 and the one-way clutch shaft member 15, and as will be described later, a "predetermined play" is intentionally allowed between the motor shaft fixing member 20 and the one-way clutch shaft member 15.
[0023] In this way, it is not easy to manufacture and arrange the motor shaft 11 and the one-way clutch shaft member 15 so as to maintain strict coaxiality. Taking into consideration the manufacturing cost, it is necessary to manufacture and arrange the motor shaft 11 and the one-way clutch shaft member 15 so as to maintain strict coaxiality. 5 One-way clutch for driving force 16 By transmitting the necessary and sufficient force to the motor shaft, 11 Regardless of the coaxiality of the one-way clutch shaft (axis), the motor 5 One-way clutch from 16 This enables the transmission of rotation to the drive shaft, extending product life and providing a one-way clutch. 16 By reducing the outer diameter and making the bearings smaller, it is possible to provide an electric reel that can be manufactured at low cost.
[0024] More specifically, as shown in Figures 4 to 7, in an electric reel 1 according to one embodiment of the present invention, the motor shaft fixing member 20 has a recess 24 at one end (first end) in the axial direction of the motor shaft 11, and has a fitting portion 25 at the other end (second end) into which the motor shaft 11 is press-fitted.
[0025] 4 to 7, in the electric reel 1 according to one embodiment of the present invention, the one-way clutch shaft member 15 has a protrusion 28 at one end (first end) 26 in the axial direction of the one-way clutch shaft member 15, and the protrusion 28 of the one-way clutch shaft member 15 is engaged with the recess 24 of the motor shaft fixing member 20. 28 The engagement (fitting) width of the recess 24 The engagement (fitting) width is made smaller than the engagement (fitting) width, leaving a gap, and thus it is possible to allow for play.
[0026] 4 to 7, in the electric reel 1 according to one embodiment of the present invention, the other end (second end) 27 of the one-way clutch shaft member 15, as seen in the axial direction of the one-way clutch shaft member 15, is inserted into and fitted with the cylindrical one-way clutch 16. In this way, it is possible to prevent the one-way clutch shaft member 15 from rotating reversely.
[0027] The engagement structure between the one-way clutch shaft member 15 and the motor shaft fixing member 20 can basically be any structure that allows for mechanical rotation transmission and provides a predetermined gap between them. Below, other aspects of the engagement structure between the one-way clutch shaft member 15 and the motor shaft fixing member 20 in the electric reel 1 according to one embodiment of the present invention will be described.
[0028] First, as shown in Figure 8, in an electric reel 1 according to another embodiment of the present invention, the one-way clutch shaft member 15 has a key member 29 at one end (first end) 26 in the axial direction of the one-way clutch shaft member 15, and the key member 29 of the one-way clutch shaft member 15 is engaged with a key groove 30 of the motor shaft fixing member 20. In this case, the engagement width of the key member 29 is Person in charge The gap is made smaller than the mating width, and thus it is possible to allow for play.
[0029] Next, as shown in Figure 9, in an electric reel 1 according to another embodiment of the present invention, the one-way clutch shaft member 15 has a semicircular protrusion 31 at one end (first end) 26 in the axial direction of the one-way clutch shaft member 15, and the semicircular protrusion 31 of the one-way clutch shaft member 15 engages with a semicircular recess 32 of the motor shaft fixing member 20. In this case, the engagement width of the semicircular protrusion 31 is smaller than the engagement width of the semicircular recess 32, leaving a gap, and in this way it is possible to allow for play.
