[Problems to be solved by the invention]

However, when the conventional speed reducer using planetary gears supported by a cantilever is applied to an electric reel for fishing, especially when the load is high, the support shaft of the planetary gear will deflect, so the planetary gear The noise generated by the deflection will become larger, so there is still room for improvement at this point. In addition, due to the aforementioned deflection on the planetary gears, the rotation efficiency is reduced, and there is a problem of reduced efficiency as a reduction gear.

The present invention is an invention developed in view of this situation, and its purpose is to provide a reduction gear and an electric reel that can increase the rotation efficiency by suppressing the deflection of the planetary gear and can improve the efficiency of the reduction gear. The manufacturing method of the deceleration device and the electric reel for fishing. [Means to solve the problem]

The deceleration device of the electric cord reel of the present invention is a deceleration device of the electric cord reel that decelerates the rotational driving force of the motor and then transmits it to the rotation driving part, and is characterized by having: a sun gear provided on the motor rotating shaft of the aforementioned motor; The sun gear is meshed with a plurality of planetary gears having a planetary gear supporting shaft; it is arranged coaxially with the aforementioned sun gear, and has an inner peripheral gear that meshes the aforementioned plurality of planetary gears with an inner peripheral portion, and along the inner peripheral gear, the aforementioned A ring gear in which a plurality of planetary gears move around; and a carrier that supports both ends of the planetary gear supporting shaft of the plurality of planetary gears, and with the orbiting movement of the plurality of planetary gears, centering on the sun gear The rotation transmits the rotation driving force to the rotation driving unit.

According to the deceleration device of the electric reel of the present invention, the planetary gear supporting shafts of the plurality of planetary gears are supported by the carrier at both ends, so that the supporting shaft can reduce the deflection when the load is high, and also suppress the deflection caused The noise. In addition, because the planetary gear support shaft is fixed to the carrier by the support at both ends, the planetary gear supported by the cantilever as in the past is a flange member provided on the planetary gear support shaft as the anti-dropping member of the planetary gear It becomes unnecessary. Therefore, the shaft diameter of the planetary gear support shaft can be reduced, for example, a planetary gear with a smaller number of teeth can be selected, and the degree of freedom in selecting the reduction ratio as a reduction gear can be increased. In addition, by omitting the flange member, it is possible to ensure a long space for the bearing length of the planetary gear support shaft. Therefore, the bearing length can be increased and the meshing state of the planetary gears can be stabilized. In addition, according to the structure of the present invention, as described above, the planetary gear support shaft can be reduced in diameter compared to the past. Therefore, by reducing the peripheral speed of the planetary gear to the support shaft, the friction loss between the two can be reduced. The rotation efficiency can be further improved.

(2) The carrier system has a pair of fixed plates arranged on both sides of the planetary gear supporting shaft in the axial direction, and the first fixed plate of the planetary gear supporting shaft is supported by one of the pair of fixed plates. The shaft diameter of the first shaft fixing part is formed to be smaller than the shaft diameter of the other parts. The first shaft fixing part is fixed to the first fixing plate by a riveting part, and is supported by the second shaft of the other second fixing plate. The fixing part is preferably fixed in a state of being fitted into the aforementioned second fixing plate.

In this case, the planetary gear supporting shaft system forms a stepped portion between the first shaft fixing portion and the other shaft portions. Using this stepped planetary gear support shaft, with the second shaft fixing part fitted to the second fixing plate, the first shaft fixing part is riveted and the riveting part is locked to support the planetary gear The shaft is fixed in the anti-dropping state. In this way, in the present invention, the planetary gear support shaft can be fixed to the pair of fixed plates so as to be non-rotatable by a simple shaft shape.

(3) The second shaft fixing portion of the planetary gear support shaft is preferably fixed to the second fixing plate by light press fitting.

In this case, during assembly before fixing the first shaft fixing part of the planetary gear support shaft to the first fixing plate of the carrier by riveting, the second shaft fixing part is fixed to the second fixing plate by light pressing. The fixed plate can prevent the planetary gear support shaft from falling off and improve workability.

(4) A cylindrical frame is provided that houses the motor and has an end plate that rotatably supports the rotation shaft of the motor. The end plate system is interposed between the motor and the sun gear, and the motor is fixed. The aforementioned end plate is better.

In this case, compared to the case where the motor rotating shaft is fixed on the side of the motor end cover of the cylindrical frame (the side opposite to the end plate via the motor), the contact area between the motor and the cylindrical frame is increased and the motor can be driven The heat generated at the time is efficiently transmitted to the cylindrical frame and dissipated. Furthermore, in the present invention, compared to the conventional case where the motor rotating shaft is fixed on the side of the motor end cover, since the assembly part of the motor is formed close to the sun gear, the length of the motor in the assembly part (lever ratio) is reduced . Therefore, compared to the conventional fixing structure in which the motor end cover is fixed, the flatness accuracy of the assembled part can be relaxed.

(5) The carrier may be provided with a carrier bearing portion, which is arranged coaxially with the sun gear and axially supports the sun gear or the motor rotation shaft from the outside in the radial direction.

In this case, since the carrier is supported by the sun gear or the motor rotation shaft via the carrier bearing portion, the carrier bearing portion can be reduced in size. In addition, it is also possible to suppress an increase in the length dimension in the direction of the motor rotation axis for arranging the carrier bearing. That is, it can be suppressed that the dimension in the axial direction of the accommodating cylinder is increased due to the installation of a large bearing, as in the case where the bearing is supported by the outer peripheral surface of the accommodating cylinder of the carrier. In addition, by supporting the carrier on the sun gear or the motor rotating shaft, the meshing accuracy of the sun gear and the planetary gear can be improved.

(6) The manufacturing method of the deceleration device of the electric reel of the present invention is the manufacturing method of the deceleration device of the electric reel described in any one of (1) to (5), characterized in that the aforementioned carrier system is integrated It is formed to support both ends of the planetary gear support shaft after arranging the plurality of planetary gears inside the carrier.

According to the method for manufacturing the reduction gear of the electric reel of the present invention, the planetary gear supporting shafts of the plurality of planetary gears are supported on the carrier at both ends, so that the supporting shaft can reduce the deflection under high load, and can also suppress Noise caused by deflection. Also, in the same way as the above, the planetary gear support shaft is fixed to the carrier by the support at both ends, so the flange member of the planetary gear of the conventional cantilever support can be omitted, so the speed reduction as a reduction gear can be improved. The freedom of ratio selection can increase the length of the bearing to stabilize the meshing state of the planetary gears.

(7) The carrier system has a pair of fixed plates arranged on both sides of the axial direction of the planetary gear supporting shaft of the plurality of planetary gears, and the planetary gears are arranged at intervals in the circumferential direction. The planetary gear holding wall that connects the pair of fixed plates to each other. The planetary gear holding wall is formed by processing T-slots from the outer peripheral side of the fixed plate, and from the inner peripheral side of the fixed plate by end milling Knife processing is to cut the inner peripheral end of the aforementioned planetary gear holding wall.

In this case, in order to make the inner peripheral end of the planetary gear holding wall that connects the fixing plates of the carrier to a desired position, the position can be adjusted by cutting by end milling. Therefore, it is possible to ensure a clearance between the outer peripheral portion of the planetary gear and the planetary gear holding wall, and it is possible to prevent the two from approaching. In addition, in addition to T-groove processing, the planetary gear holding wall is processed by end milling, thereby preventing the planetary gear holding wall from becoming thinner.

(8) The manufacturing method of the deceleration device of the electric reel of the present invention is based on the carrier used in the manufacturing method of the deceleration device of the electric reel as described in any one of (1) to (5) above. A method of manufacturing a reduction gear of an electric reel in which a plurality of planetary gears are divided into a pair of fixed plates, and the plurality of planetary gears are arranged and fixed between the pair of fixed plates, characterized by: arranging the plurality of the aforementioned plurality on one of the first fixed plates The manufacturing process of a planetary gear and a connecting rod shaft connecting the aforementioned pair of fixed plates; and after arranging the plurality of planetary gears and the aforementioned connecting rod shaft, at least one end of the aforementioned connecting rod shaft is fixed by riveting The manufacturing process.

According to the manufacturing method of the reduction gear of the electric reel of the present invention, since a pair of fixing plates are divided, when a plurality of planetary gears are inserted between the fixing plates to be integrated, the connecting rod shaft can be integrated At least one of the ends is assembled by a simple method of riveting and fixing to the fixing plate.

A carrier bearing portion 14 is provided between the inner peripheral surface 63 a and the shaft front end portion 41 a of the motor rotating shaft 41. That is, the carrier 6 (carrier body 63) is rotatably provided around the sun gear 11 (motor rotation shaft 41) via the carrier bearing portion 14, and can rotate at a rotation number different from that of the sun gear 11.

The first fixing flange 64 and the second fixing flange 65 have the same outer diameter as shown in FIGS. 9 to 12 and are integrally provided via a connecting wall 66 (planetary gear holding wall). The sun gear 11 is arranged in a state in which the circular inner peripheral portion 64a formed in the central portion of the first fixing flange 64 is inserted between the flanges 64 and 65 of both sides. The shaft front end portion 41a of the motor rotating shaft 41 is arranged in a state of protruding from a center hole 65a formed in the central portion of the second fixing flange 65 toward the front end side. In addition, between the first fixed flange 64 and the second fixed flange 65, the three planetary gears 12 meshing with the sun gear 11 are rotatably supported at a certain interval in the circumferential direction.

Both ends 121a, 121b of the planetary gear support shaft 121 of each planetary gear 12A, 12B, 12C are fixed by the first fixing flange 64 and the second fixing flange 65. The planetary gears 12A, 12B, and 12C are respectively connected to at least the aforementioned outer peripheral portion (the aforementioned radially outer portion 122b in the tooth portion 122) in a state where it protrudes from the outer peripheral portion of the first fixed flange 64 and the second fixed flange 65 It is arranged so as to mesh with the ring gear 13 with the portion 122a on the outer side in the radial direction.

The connecting wall 66 is provided at a position where there is no interference from the planetary gears 12A, 12B, and 12C at intervals. The connecting wall 66 is formed by T-groove processing from the outer peripheral portion 64b side of the first fixed flange 64. By end milling from the inner peripheral portion 64a side of the first fixed flange 64, the connecting wall 66 The inner peripheral end portion 66a of the steel plate is cut to form a concave curved surface closer to the outer peripheral side than the inner peripheral portion 64a. Thereby, since the position of the inner peripheral end portion 66a of the connecting wall 66 is located closer to the outer peripheral side than the inner peripheral portion 64a, a large clearance between the planetary gear 12 and the connecting wall 66 can be ensured. In addition, by performing end mill processing from the inner peripheral portion 64a side of the first fixing flange 64, it is possible to prevent the generation of a thin wall.

As shown in FIG. 13, the shaft diameter of the first shaft fixing portion 121a of the planetary gear support shaft 121 supported by one of the first fixing flanges 64 is formed to be larger than that of the other part (the shaft body part of figure number 121c) The shaft diameter is smaller. The first shaft fixing portion 121a is fixed by the caulking portion 124 to which the first fixing flange 64 is caulked. The second shaft fixing portion 121 b supported by the other second fixing flange 65 is fixed in a state of being fitted to the second fixing flange 65. The second shaft fixing portion 121b of the planetary gear support shaft 121 is fixed to the second fixing flange 65 by light pressing. Here, the so-called light press-fitting refers to the press-fitting that requires considerable force while assembling and disassembling, and requires high-precision fixed installation.

An outer waterproof seal 67 is provided between the outer peripheral surface 63b of the carrier body 63 of the first support 61 and the inner peripheral surface 45b on the second space 46B side of the housing tube 45 of the motor housing 44.

In the electric cord reel 1 thus constructed, by connecting the power supply line connected to the external power source to the power supply connection part, the motor is formed to be driveable. In addition, when the clutch mechanism 5 is in the clutch-on state, the motor 4 is driven by operating the handle 20 for winding or operating the power lever, and the driving force is transmitted to the reel 3 by the reduction gear 10, so that the reel 3 Rotate to wind up the fishing line. In addition, the rotational driving force of the motor 4 is decelerated by a plurality of planetary gears 12A, 12B, and 12C and transmitted to the reel 3. In addition, if the clutch operating member 50 is operated to switch the clutch mechanism 5 to the clutch off state, the spool 3 is switched to the spool free state, and the fishing line can be continuously sent out.

Next, as a manufacturing method of assembling the planetary gear 12 to the carrier 6 in the reduction gear 10 of the electric reel 1, as shown in FIG. 5, the first fixing flange 64 and the second fixing flange 65 of the carrier 6 are mutually After the three planetary gears 12A, 12B, and 12C are arranged in between, the respective planetary gear support shafts 121 are used to penetrate the rotation shaft holes of the planetary gears 12. Then, as shown in FIG. 13, the second shaft fixing portion 121 b of the planetary gear support shaft 121 inserted into the rotating shaft hole is fixed to the second fixing flange 65 by light pressing. At the same time, the first shaft fixing portion 121a is fixed by the caulking portion 124 formed by caulking the first fixing flange 64. Thereby, the planetary gear support shaft 121 becomes a support structure at both ends fixed to the two fixing flanges 64 and 65.

Next, based on the drawings, the method of manufacturing the speed reduction device 10 of the electric cord reel 1 and the speed reduction device 10 of the electric cord reel 1 and the function of the electric cord reel 1 are described in detail. As shown in FIG. 4, in the reduction gear 10 of the electric reel 1 of this embodiment, the two ends of the planetary gear support shaft 121 of the plurality of planetary gears 12A, 12B, and 12C are supported by the carrier 6 as shown in FIG. Therefore, it is possible to reduce the deflection of the planetary gear support shaft 121 when the load is high, and to suppress the noise caused by the deflection.

In addition, because the planetary gear support shaft 121 is fixed to the carrier 6 by the support at both ends, the planetary gear supported by the cantilever as the conventional planetary gear is used as the anti-dropping member of the planetary gear. The edge member becomes unnecessary. Therefore, the shaft diameter of the planetary gear support shaft 121 can be reduced, for example, a planetary gear with a smaller number of teeth can be selected, and the degree of freedom of selection as a reduction ratio of the reduction gear 10 can be increased. Furthermore, by omitting the flange member, it is possible to ensure a space that can make the bearing length of the planetary gear support shaft 121 longer. Therefore, the bearing length can be increased, and the meshing state of the planetary gear 12 can be stabilized. In addition, in this embodiment, as described above, the planetary gear support shaft 121 can be reduced in diameter compared to the past. Therefore, by reducing the peripheral speed of the planetary gear 12 to the support shaft, the friction loss between the two can be reduced. The rotation efficiency can be further improved.

In addition, in the present embodiment, the planetary gear support shaft 121 forms a stepped portion between the first shaft fixing portion 121a and the other shaft portion 121c. Using this stepped planetary gear support shaft 121, with the second shaft fixing portion 121b fitted to the second fixing flange 65, the first shaft fixing portion 121a is caulked and the caulking portion 124 is locked , The planetary gear support shaft 121 can be fixed in the anti-dropping state. In this way, in this embodiment, the planetary gear support shaft 121 can be fixed non-rotatably to the pair of fixing flanges 64 and 65 by a simple shaft shape.

Also, in this embodiment, during assembly before the first shaft fixing portion 121a of the planetary gear support shaft 121 is fixed to the first fixing flange 64 of the carrier 6 by riveting, the Since the biaxial fixing portion 121b is fixed to the second fixing flange 65, it is possible to prevent the planetary gear support shaft 121 from falling off, and it is possible to improve workability.

In addition, in this embodiment, a motor housing 44 is provided for accommodating the motor 4 and having a partition 46 rotatably supporting the motor rotation shaft 41. The partition 46 is interposed between the motor 4 and the sun gear 11, and the motor 4 is fixed to The partition wall 46 therefore increases the contact area between the motor 4 and the motor housing 44 compared to the case where the motor rotating shaft 41 is fixed on the motor end cover 434 side of the motor housing 44 (the side opposite to the partition wall 46 via the motor 4). The heat generated when the motor is driven can be efficiently transmitted to the motor housing 44 for heat dissipation.

Moreover, in this embodiment, compared to the conventional case where the motor rotating shaft 41 is fixed on the motor end cover 434 side, the assembly part of the motor 4 is formed close to the sun gear 11, so the length of the assembly part of the motor 4 (Leverage ratio) becomes smaller. Therefore, compared to the conventional fixing structure in which the motor end cover 434 side, which is the base end, is fixed, the accuracy of the flatness of the assembly portion can be relaxed.

In addition, in this embodiment, since the carrier 6 is supported by the sun gear 11 or the motor rotating shaft 41 via the carrier bearing portion 14, the carrier bearing portion 14 can be reduced in size. In addition, it is possible to suppress an increase in the length dimension in the direction of the motor rotating shaft 41 for arranging the carrier bearing portion 14. That is, it can be suppressed that the dimension in the axial direction of the accommodating cylinder is increased due to the installation of a large bearing, as in the case where the bearing is supported by the outer peripheral surface of the accommodating cylinder of the carrier. Furthermore, by supporting the carrier 6 on the sun gear 11 or the motor rotating shaft 41, the meshing accuracy of the sun gear 11 and the planetary gear 12 can be improved.

In the deceleration device of the electric reel of the present embodiment, the method of manufacturing the deceleration device of the electric reel, and the electric reel for fishing constructed as described above, the rotation efficiency can be improved by suppressing the deflection of the planetary gear 12. Improve the efficiency of the deceleration device 10.

In the second modification, only the lower end portion 68b of the second link shaft 68B is crimped from the outside in the direction of the carrier axis C3 to form the crimped portion R. Thereby, the first fixing flange 64A and the second fixing flange 65A are fixed by the second link shaft 68B, and the three planetary gears 12A, 12B, and 12C are also fixed.

In the second modification, the flange portion 681 is formed on a single side of the second link shaft 68B, and the flange portion 68l is engaged with the stepped portion 64g, so that the upper end portion 68d of the second link shaft 68B By riveting, the pair of fixing flanges 64A and 65A can be fixed by the second link shaft 68B. Therefore, compared to the case of the first modification in which both sides of the second link shaft 68B are riveted, the riveting can be performed efficiently and easily, and time-consuming work can be reduced.

The first shaft portion 126A and the second shaft portion 126B are arranged coaxially via the projecting ring portion 126C. The first shaft portion 126A is inserted through and fixed to the bearing 125 of the planetary gear 12. The second shaft portion 126B has a smaller diameter than the first shaft portion 126A, and the upper end portion 126a of the support shaft 126 and the upper end portion 126a and The lower end 126b is riveted. The protruding ring portion 126C is formed to have a larger diameter than the shaft diameter of the first shaft portion 126A.

When the second shaft portion 126B is penetrated through the second insertion hole 65d of the first fixing flange 64A, and the first fixing flange 64A is brought into contact with the upper end surface 126d of the protruding ring portion 126C, the upper end of the second shaft portion 126B The portion 126a is formed in a state protruding upward from the first fixing flange 64A. In addition, the ends 126a, 126b protruding from each of the fixing flanges 64A, 65A are riveted. Thereby, the planetary gear 12 is fixed to the pair of fixed flanges 64A, 65A by riveting the support shaft 126. In this case, since the contact area between the protruding ring portion 126C and the upper end portion 125a of the bearing 125 and the first fixing flange 64A can be increased, it is possible to suppress riveting separation.
