Technical Field

The present invention relates to a speed reducer for an electric reel, a method of manufacturing the speed reducer for the electric reel, and an electric reel for fishing.

Background

Disclosure of Invention

[ technical problem to be solved by the invention ]

However, when a speed reducer using a conventional cantilever-supported planetary gear is used for an electric fishing reel, the support shaft of the planetary gear is bent particularly under high load, and noise due to the bending of the planetary gear is increased.

Further, there is a problem that the above-described planetary gear is deflected to lower the rotation efficiency, and the efficiency of the reduction gear is lowered.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a speed reduction device for an electric reel, a method of manufacturing the speed reduction device for the electric reel, and an electric reel for fishing, which can improve the efficiency of the speed reduction device by suppressing the deflection of a planetary gear to improve the rotation efficiency.

[ technical means for solving problems ]

The present invention relates to a speed reducer for an electric reel, which reduces the rotational driving force of a motor and transmits the reduced rotational driving force to a rotational driving unit, the speed reducer comprising: a sun gear, a plurality of planet gears, a ring gear, and a planet carrier, wherein the sun gear is provided to a motor rotation shaft of the motor; the plurality of planetary gears are engaged with the sun gear and have planetary gear support shafts; the ring gear is provided coaxially with the sun gear, has an inner peripheral gear for meshing the plurality of planetary gears at an inner peripheral portion, and moves the plurality of planetary gears around the inner peripheral gear; the carrier supports both ends of the planetary gear support shaft of the plurality of planetary gears, and rotates around the sun gear to transmit a rotational driving force to the rotational driving unit as the plurality of planetary gears move around.

(1) According to the speed reducer of the electric fishing reel of the present invention, since both ends of the planetary gear support shaft of the plurality of planetary gears are supported by the carrier, it is possible to reduce the deflection of the support shaft at the time of high load, and it is possible to suppress the noise caused by the deflection.

Further, since the planetary gear support shaft is supported and fixed to the carrier at both ends, it is not necessary to provide a flange member as a retaining member for the planetary gear on the planetary gear support shaft, as in the case of the conventional planetary gear supported by a cantilever type. Therefore, the shaft diameter of the planetary gear support shaft can be reduced, and for example, a planetary gear having a smaller number of teeth can be selected, thereby improving the degree of freedom in selecting the reduction ratio of the reduction gear.

Further, by omitting the flange member, a space in which the bearing length of the planetary gear support shaft can be increased can be ensured. Therefore, the length of the bearing can be increased to stabilize the meshing state of the planetary gears.

Further, according to the configuration of the present invention, since the diameter of the planetary gear support shaft can be made smaller than that of the conventional art as described above, the circumferential velocity of the planetary gear with respect to the support shaft can be reduced to reduce the friction loss therebetween, thereby further improving the rotational efficiency.

(2) Preferably, the carrier has a pair of fixed plates disposed on both sides of the planetary gear support shaft in the axial direction, and in the planetary gear support shaft, a shaft diameter of a 1 st shaft fixing portion supported by one of the pair of fixed plates is formed smaller than a shaft diameter of the other portion, the 1 st shaft fixing portion is fixed to the 1 st fixed plate by a press fastening portion, and a 2 nd shaft fixing portion supported by the other 2 nd fixed plate is fixed in a state of being fitted to the 2 nd fixed plate.

In this case, a step portion is formed between the 1 st shaft fixing portion and the other shaft portion on the planetary gear support shaft. With this stepped planetary gear support shaft, the 1 st shaft fixing portion is press-fastened and the press-fastened portion is locked in a state where the 2 nd shaft fixing portion is fitted to the 2 nd fixing plate, whereby the planetary gear support shaft is fixed in a state where it is prevented from falling off. In this way, in the present invention, the planetary gear support shaft can be fixed to the pair of fixed plates so as not to be rotatable with respect to the pair of fixed plates by a simple shaft shape.

(3) Preferably, the 2 nd shaft fixing portion of the planetary gear support shaft is fixed to the 2 nd fixing plate by slight press fitting.

In this case, when the assembly is performed before the 1 st shaft fixing portion of the planetary gear support shaft is fixed to the 1 st fixing plate of the carrier by press fastening, the 2 nd shaft fixing portion is fixed to the 2 nd fixing plate by slight press fitting, so that the planetary gear support shaft can be prevented from coming off, and the workability can be improved.

(4) The speed reducer of an electric reel according to the present invention may be characterized by being provided with a cylindrical frame that houses the motor and has an end plate that rotatably supports the motor rotation shaft, the end plate being disposed (interposed) between the motor and the sun gear, and the motor being fixed to the end plate.

In this case, as compared with a case where the motor rotation shaft is fixed to the motor end cap (motor end cap) side of the tubular frame (the side opposite to the end plate across the motor), the contact area between the motor and the tubular frame can be increased, and heat generated when the motor is driven can be efficiently transmitted to the tubular frame to be radiated.

In addition, in the present invention, as compared with the case where the motor rotation shaft is fixed to the motor end cap side in the related art, the length (lever ratio) of the motor of the assembly portion becomes smaller by the assembly portion of the motor being located close to the sun gear. Therefore, compared with a fixing structure for fixing the motor rotating shaft on the motor end cap side in the prior art, the flatness accuracy of the assembled part can be alleviated.

(5) The speed reducer of an electric reel according to the present invention may be characterized in that the carrier is provided with a carrier bearing portion which is disposed coaxially with the sun gear and supports the sun gear or the motor rotation shaft from a radially outer shaft.

In this case, the carrier is configured to support the sun gear or the motor rotation shaft via the carrier bearing portion, and therefore the carrier bearing portion can be reduced in size. Further, an increase in the length of the carrier in the motor rotation axis direction for disposing the carrier bearing portion can be suppressed. That is, the following can be suppressed: as in the case of performing the shaft support on the outer peripheral surface of the accommodating cylinder of the carrier, the dimension of the accommodating cylinder in the axial direction becomes longer as a large bearing is provided.

Further, the accuracy of meshing between the sun gear and the planetary gears can be improved by supporting the sun gear or the motor rotation shaft with the carrier.

(6) The method of manufacturing an electric reel speed reducer according to the present invention is the method of manufacturing an electric reel speed reducer according to any one of the above items (1) to (5), wherein the carrier is integrally formed, and after the plurality of planetary gears are disposed inside the carrier, the carrier supports both ends of the planetary gear support shaft.

According to the method of manufacturing the speed reducer of the electric reel of the present invention, since both ends of the planetary gear support shaft of the plurality of planetary gears are supported by the carrier, it is possible to reduce the deflection of the support shaft at the time of high load, and it is possible to suppress the noise due to the deflection.

Further, since the planetary gear support shaft is fixed to the carrier by being supported at both ends as described above, a flange member such as a planetary gear supported in a cantilever manner in the conventional art can be omitted, and the degree of freedom in selecting the reduction ratio of the reduction gear transmission can be improved, and the length of the bearing can be increased to stabilize the meshing state of the planetary gears.

(7) The method of manufacturing the speed reducer of the electric reel may be characterized in that the carrier has a pair of fixing plates disposed on both sides of the planetary gear support shaft of the plurality of planetary gears in the axial direction, a planetary gear holding wall connecting the pair of fixing plates is provided between the planetary gears disposed at intervals in the circumferential direction, the planetary gear holding wall is formed by a T-shaped groove machining from the outer circumferential side of the fixing plate, and an inner circumferential end portion of the planetary gear holding wall is cut by an end mill (end mill) machining from the inner circumferential side of the fixing plate.

In this case, the inner peripheral end portion of the planetary gear holding wall connecting the fixed plates of the carrier is cut by end milling so as to be a desired position, and the position can be adjusted. Therefore, a clearance (clearance) between the outer peripheral portion of the planetary gear and the planetary gear holding wall can be secured, and both can be prevented from coming close to each other. In addition, in the machining of the planetary gear holding wall, a method of performing end mill machining may be employed in addition to the T-groove machining, whereby the planetary gear holding wall can be prevented from being thinned.

(8) A method of manufacturing a speed reducer of an electric reel according to the present invention is a method of manufacturing a speed reducer of an electric reel, in which a carrier used in the method of manufacturing a speed reducer of an electric reel according to any one of (1) to (5) above has a pair of fixing plates that are divided from each other, and the plurality of planetary gears are disposed between the pair of fixing plates to fix the speed reducer, the method including: disposing the plurality of planetary gears and a link shaft (link draft) connecting the pair of fixed plates to one of the first fixed plates 1; and a step of fixing at least one end of the link shaft by press fastening after the plurality of planetary gears and the link shaft are arranged.

According to the method of manufacturing the speed reducer of the electric reel according to the present invention, since the pair of fixing plates are divided, at least one end of the link shaft is fixed to the fixing plate by press fastening when the plurality of planetary gears are assembled and integrated between the fixing plates.

(9) The electric fishing reel according to the present invention is characterized in that the speed reduction device for an electric fishing reel according to any one of (1) to (5) is disposed in a reel body, the carrier is connected to a spool provided in the reel body, and the rotational driving force of the motor is reduced by the plurality of planetary gears supported by both ends of the carrier to rotate the spool.

According to the electric fishing reel of the present invention, both ends of the planetary gear support shaft of the plurality of planetary gears are supported by the carrier by using the speed reduction device, so that the deflection of the support shaft at the time of high load can be reduced, and the noise caused by the deflection can be suppressed. Therefore, the rotation of the spool to which the rotational driving force of the motor is transmitted through the speed reduction device can be stabilized.

[ Effect of the invention ]

According to the speed reducer of the electric fishing reel, the manufacturing method of the speed reducer of the electric fishing reel, and the electric fishing reel of the present invention, the rotation efficiency can be improved by suppressing the deflection of the planetary gear, and the efficiency of the speed reducer can be improved.

(fishing line reel unit)

The reel unit 2 includes: a main body frame 21; a cover (cover)22 covering a part of the main body frame 21; and a water depth display unit 23 located above the main body frame 21.

The main body frame 21 is an integrally formed member made of, for example, synthetic resin or metal. The main body frame 21 has: a right side plate 21A located on the handle 20 side with the spool 3 therebetween in the left-right direction L1; a left side plate 21B located on the opposite side of the right side plate 21A; and a plurality of connecting members 21C connecting the right side plate 21A and the left side plate 21B.

Further, a support portion for supporting the spool 3 and the motor 4, and a rotation driving mechanism such as the clutch mechanism 5 and the reduction gear 10 are disposed on each of the side plates 21A and 21B.

The end portions of the spool rotation shaft (not shown) of the spool 3 are attached to the right side plate 21A and the left side plate 21B in a freely rotatable supported state. The coupling member 21C shown in fig. 2 is formed in a plate shape and couples lower portions of the right side plate 21A and the left side plate 21B. A fishing rod attachment portion 24 is attached to one of the coupling members 21C at a substantially central portion in the left-right direction L1, and a fishing rod is attached to the fishing rod attachment portion 24.

The cover 22 has a right cover 22A, a left cover 22B, and a front cover 22C.

The left cover 22B covers the left side plate 21B with a predetermined storage space, and is fastened to an outer edge portion of the left side plate 21B by, for example, screwing. The front cover 22C covers the front of the main body frame 21.

As shown in fig. 3, a connector (connector)28 is attached to a front lower portion of the right side plate 21A with a connection end 28a facing downward, wherein the connector 28 is used for connecting a power supply line from the outside.

(Water depth display section)

As shown in fig. 1, the water depth display unit 23 is disposed between the right side plate 21A and the left side plate 21B. The water depth display unit 23 includes: a display panel 23A which is constituted by a liquid crystal display (display) capable of displaying the depth of a fishhook assembly which can be attached to the top end of a fishing line in water; and a reel control unit (not shown). The water depth display unit 23 is a casing portion placed on the upper portions of the right and left side plates 21A and 21B, is fixed to the outer side surfaces of the right and left side plates 21A and 21B by screwing, and has a plurality of (3 in the present embodiment) operation buttons 23B for performing display operation.

(handle)

As shown in fig. 1 and 2, the handle 20 has: a handle arm (handle arm)25 attached to the distal end portion 20a of the handle shaft so as to be unrotatable; a handle knob (handle knob)26 attached to one end of the handle arm 25 so as to be rotatable about an axis parallel to the handle axis C1; and a drag mechanism (drag) 27 disposed on the reel unit 2 side.

The torque from the handle 20 is directly transmitted to the spool 3 in a state where the clutch mechanism 5 is in a clutch engaged (ON).

(winding reel)

The spool 3 is rotatably provided between the right side plate 21A and the left side plate 21B via bearings (not shown). The spool 3 has: a not-shown spool rotation shaft; a bobbin body 32 which is cylindrical, is disposed coaxially with the bobbin rotation shaft, and is rotatable in conjunction with the bobbin rotation shaft; and flange portions 33 having radially outward diameters at both ends of the winding main body portion 32.

As described above, the spool 3 is driven to rotate by the reduction gear unit 10 via the spool drive mechanism not shown, and is interlocked with the clutch mechanism 5 driven by the clutch operation member 50. The spool rotation shaft is rotatably supported by the right side cover 22A and the left side cover 22B through bearings.

(Clutch mechanism)

The clutch mechanism 5 can be switched between a clutch engaged (ON) state in which the rotation of the handle 20 can be transmitted to the spool 3 and a clutch disengaged (OFF) state in which the rotation of the handle 20 cannot be transmitted to the spool 3 by operating the clutch operating member 50. In the clutch engagement position, the rotation of the pinion gear (piniongear) is transmitted to the spool rotation shaft to be in a clutch engagement state, and the pinion gear and the spool rotation shaft can rotate integrally. In the clutch disengaged position, the rotation of the pinion gear is not transmitted to the spool rotation shaft, and therefore the spool 3 is in the clutch disengaged state and can rotate freely.

(Clutch operating member)

As shown in fig. 1, the clutch operating member 50 is a member for switching the clutch mechanism 5 between a clutch engaged state and a clutch disengaged state. The clutch operating member 50 is provided at the rear portion of the reel unit 2 between the right side plate 21A and the left side plate 21B so as to be movable in a direction approaching the rod attachment portion 24 and in a direction separating from the rod attachment portion 24. In the present embodiment, the clutch operating member 50 is provided so as to be swingable around the spool rotation shaft.

(spool driving mechanism)

The bobbin driving mechanism drives the bobbin 3 in the winding direction. In addition, at the time of winding, the drag mechanism 27 generates drag force on the spool 3 to prevent the fishing line from being broken.

The drag mechanism 27 is disposed coaxially with the handle shaft between the handle arm 25 of the handle 20 and the right side cover 22A. The spool driving mechanism includes: the above-mentioned motor 4, which is prohibited from rotating in the winding direction by an anti-reverse portion in the form of a roller clutch (not shown); and a rotation transmission mechanism for transmitting the rotation of the motor 4 to the spool 3 while decelerating the rotation thereof, or transmitting the rotation of the handle 20 to the spool 3 while accelerating the rotation thereof.

(Motor)

Here, the following description will be made with the shaft distal end portion 41a side of the motor rotating shaft 41 as the distal end side and the shaft proximal end portion 41b side as the proximal end side on the motor axis O.

The case 43 forms a housing of the motor 4. The case 43 has: a cylindrical body 431 covering the entire circumference of the motor main body 42 having the motor rotating shaft 41 at the center of rotation; a tip end plate 432 that closes the tip end of the cylindrical body 431; a 1 st central barrel 433A, which supports a 1 st bearing 435 at the center of the top end plate 432; and a 2 nd central barrel 433B, which supports a motor waterproof seal (seal)436 at the center of the top end plate 432.

The tip plate 432 is formed in a ring shape having an opening 432B on the inner side thereof, the outer peripheral portion of the tip plate 432 is connected to the tip 431a of the cylindrical body 431, and the opening 432B is connected to the 1 st central barrel 433A and the 2 nd central barrel 433B. A female screw hole 432a penetrating in the thickness direction is formed in the tip end plate 432. A fixing screw 47 fixed between the top end plate 432 and the motor housing 44 is screwed into the internal screw hole 432 a.

A 1 st bearing 435 is disposed on the shaft base end portion 41B side of the motor rotary shaft 41 inside the 1 st center tube 433A, the 1 st bearing 435 rotatably supports the motor rotary shaft 41, and a motor waterproof seal 436 for blocking water leakage from the motor rotary shaft 41 is disposed inside the 2 nd center tube 433B. The motor waterproof seal 436 is located on the tip side of the motor main body 42, the 1 st bearing 435, and the tip plate 432, and thus the motor 4 (the case 43) is configured to prevent water from entering (see fig. 5).

The sun gear 11 is fixed to the motor rotating shaft 41 in a state of being inserted into the motor rotating shaft so as not to rotate, and projects from the motor waterproof seal 436 toward the shaft distal end portion 41a side.

A carrier bearing portion 14 (described later) is provided between an axial tip portion 41a of the motor rotating shaft 41 protruding further than the sun gear 11 and an inner peripheral surface 61a of the carrier 6, and the carrier bearing portion 14 rotatably supports the carrier 6.

As shown in fig. 4 to 6, a case tube 45 and a partition wall 46 (end plate) are integrally provided on the motor case 44, wherein the case tube 45 is cylindrical and houses and fixes the case 43 of the motor 4; the partition wall 46 is provided at a position near the tip end of the housing tube 45, and partitions a space inside the housing tube 45 in the direction of the motor rotation shaft 41. The motor 4 is housed in one 1 st space 46A (inner space) located on the shaft base end portion 41B side with a partition wall 46 interposed therebetween, and the sun gear 11, the planetary gears 12, the ring gear 13, and a part of the carrier 6 are disposed in the other 2 nd space 46B (outer space).

The ring gear 13 shown in fig. 7 is fitted to the inner peripheral surface 45B of the housing tube 45 on the 2 nd space 46B side so as not to be coaxially rotatable. A pair of detent projections 461 (2 nd engaging concave-convex portion) are provided on a distal end surface 46a of the partition wall 46 facing the carrier 6, and the detent projections 461 (2 nd engaging concave-convex portion) protrude toward one end side in the direction of the motor rotation shaft 41 to engage with a pair of detent recesses 132 described later.

The rotation stop protrusions 461 are formed as convex surfaces protruding in a direction orthogonal to the radial direction of the housing tube 45, and are provided at two radially opposed positions on the inner circumferential surface 45 b.

The base end surface 46b of the partition wall 46 abuts against the top end plate 432 of the case 43. A screw insertion hole 46c is formed in the partition wall 46 at a position corresponding to the female screw hole 432a of the top end plate 432. The motor 4 (the case 43) is fixed to the motor case 44 by inserting the fixing screw 47 (the fixing member) into the screw insertion hole 46c from the 2 nd space 46B side and screwing it into the female screw hole 432a of the tip end plate 432. That is, the motor housing 44 is fixed to the case 43 at a position of the motor rotating shaft 41 close to the sun gear 11.

Further, the contact portion between the partition wall 46 and the top end plate 432 may be provided with a thermally conductive grease or a thermally conductive sheet.

(reduction gear)

As shown in fig. 4, the reduction gear 10 reduces the rotational driving force of the motor 4 and transmits the reduced rotational driving force to the spool 3 (see fig. 1). As shown in fig. 5, the reduction gear transmission 10 includes: a sun gear 11 provided on a motor rotating shaft 41 of the motor 4; a plurality of planetary gears 12(12A, 12B, 12C) that mesh with the sun gear 11 and have a planetary gear support shaft 121; a ring gear 13 which is provided coaxially with the sun gear 11, has an inner peripheral gear 131 which meshes with the respective planetary gears 12 at an inner peripheral portion thereof, and moves the plurality of planetary gears 12A, 12B, and 12C around the inner peripheral gear 131; and a carrier 6 that supports both ends 121a, 121B of the planetary gear support shaft 121 of each planetary gear 12, rotates around the motor rotation shaft 41 in accordance with the circling movement of the plurality of planetary gears 12A, 12B, 12C, and transmits a rotational driving force to the spool 3.

The reduction gear 10 is configured to employ three planetary gears 12A, 12B, and 12C, and when the motor 4 is driven, the rotational driving force of the motor rotating shaft 41 is reduced in speed by the sun gear 11 and the planetary gears 12, and is transmitted to the spool 3 via the carrier 6.

The planetary gears 12A, 12B, and 12C are configured to constantly mesh with the ring gear 13 provided on the inner peripheral surface 45B at the distal end of the motor case 44.

(Sun gear)

As shown in fig. 4, 5, and 8, the sun gear 11 is coaxially fixed to a shaft distal end portion 41a of the motor rotation shaft 41. The sun gear 11 has a tooth portion 111 formed on its outer periphery. Three planetary gears 12A, 12B, and 12C are meshed with the tooth portion 111 of the sun gear 11.

(Planet gear)

As shown in fig. 4, each of the planetary gears 12A, 12B, 12C is a two-end support structure in which two ends 121a, 121B of each planetary gear support shaft 121 are supported by the carrier 6, and is provided so as to be rotatable about the planetary gear support shaft 121 by a bearing 123 shown in fig. 8.

As shown in fig. 9 and 10, the planetary gears 12A, 12B, and 12C mesh with the sun gear 11 at the radially inner portion (reference numeral 122A) of the outer peripheral teeth 122, and also mesh with the ring gear 13 at the radially outer portion (reference numeral 122B).

(Ring gear)

As shown in fig. 4, 5, and 7, the ring gear 13 is provided coaxially with the motor rotating shaft 41, and has an inner peripheral gear 131 that meshes with the three planetary gears 12A, 12B, and 12C on the inner peripheral surface thereof. The planetary gears 12A, 12B, and 12C rotate and move around the inner peripheral gear 131 while rotating on their own axes by the rotation of the sun gear 11.

The ring gear 13 is fitted in a non-rotatable state to an inner peripheral surface 45B of the motor case 44 on the 2 nd space 46B side (see fig. 5). As shown in fig. 5 and 7, the ring gear 13 has a detent recess 132, and the detent recess 132 (the 1 st engagement concave-convex portion) is formed by cutting out a portion in the circumferential direction at an outer peripheral edge portion 13a facing the partition wall 46. The detent recesses 132 form notched surfaces 132a in a direction perpendicular to the radial direction of the ring gear 13, and the detent recesses 132 are provided at two locations of the outer peripheral edge portion 13a that face each other in the radial direction of the ring gear 13.

In this way, the ring gear 13 and the partition wall 46 of the motor housing 44 are formed with engaging concave and convex portions (the rotation stop convex portion 461 and the rotation stop concave portion 132 shown in fig. 6) that protrude or recess in the direction of the motor rotation shaft 41, respectively, and are engaged with each other, whereby the rotation of the ring gear 13 relative to the motor housing 44 is regulated.

(Planet carrier)

As shown in fig. 4 and 5, the carrier 6 supports the planetary gear support shaft 121 of the three planetary gears 12A, 12B, 12C, and rotates about the motor rotation shaft 41 as the planetary gears 12A, 12B, 12C move around the ring gear 13, thereby transmitting a rotational driving force to the spool 3.

The carrier 6 has: a 1 st support body 61 that rotates around the motor rotation shaft 41 together with the planetary gears 12A, 12B, and 12C that move around the inside of the ring gear 13; and a 2 nd support body 62 that protrudes from the 1 st support body 61 to the opposite side of the partition wall 46 and transmits rotation to the spool 3. The 1 st support body 61 is disposed so as to surround the sun gear 11 from the shaft distal end portion 41a in the motor rotation shaft 41 direction, and is supported so as to be rotatable about the motor rotation shaft 41 by the carrier bearing portion 14.

The 1 st support body 61 has a carrier body 63, and the carrier body 63 has a top cylindrical shape and is rotatably supported by the shaft distal end portion 41a of the motor rotation shaft 41 through the inside. The 1 st support body 61 is provided with a pair of fixing flanges 64 and 65 arranged coaxially with the motor rotation shaft 41. The 2 nd fixing flange 65 (2 nd fixing plate) is formed in an annular shape protruding from the opening end of the carrier body 63 to the radially outer side over the entire circumference. The 1 st fixing flange 64 (1 st fixing plate) is formed in a ring shape that is disposed apart from the 2 nd fixing flange 65 toward the proximal end side and faces the proximal end side.

The carrier main body 63 has the sun gear 11 and the shaft distal end portion 41a of the motor rotating shaft 41 disposed therein, and a carrier bearing portion 14 is provided between the inner peripheral surface 63a and the shaft distal end portion 41a of the motor rotating shaft 41. That is, the carrier 6 (carrier main body 63) is provided so as to be rotatable around the sun gear 11 (motor rotation shaft 41) by the carrier bearing portion 14, and rotates at a rotation speed different from the rotation of the sun gear 11.

As shown in fig. 9 to 12, the 1 st fixing flange 64 and the 2 nd fixing flange 65 are formed to have the same outer diameter and are integrally provided via a connecting wall 66 (planetary gear holding wall). The sun gear 11 is disposed in a state of being inserted between the two flanges 64 and 65 from a circular inner peripheral portion 64a formed at a central portion of the 1 st fixing flange 64. The shaft distal end portion 41a of the motor rotating shaft 41 is disposed so as to protrude from a center hole 65a formed in the center portion of the 2 nd fixing flange 65 toward the distal end side. Further, between the 1 st fixing flange 64 and the 2 nd fixing flange 65, the three planetary gears 12 meshing with the sun gear 11 are rotatably supported with a certain interval in the circumferential direction.

Both ends 121a, 121B of the planetary gear support shaft 121 of each of the planetary gears 12A, 12B, 12C are fixed by the 1 st and 2 nd fixing flanges 64, 65. The planet gears 12A, 12B, and 12C are arranged such that at least the outer peripheral portions thereof (the radially outer portions 122B of the tooth portions 122) protrude from the outer peripheral portions of the 1 st and 2 nd fixing flanges 64 and 65, and are disposed so as to mesh with the ring gear 13 at the radially outer portions 122B.

The connecting wall 66 is provided at a position spaced apart from the respective planetary gears 12A, 12B, 12C without interfering therewith. The connecting wall 66 is manufactured by cutting by a T-groove machining from the outer peripheral portion 64b side of the 1 st fixing flange 64 and an end mill (end mill) machining from the inner peripheral portion 64a side of the 1 st fixing flange 64 so that the inner peripheral end portion 66a of the connecting wall 66 is formed into a concave curved surface that is partially recessed toward the outer peripheral side than the inner peripheral portion 64 a. Accordingly, since the position of the inner peripheral end 66a of the coupling wall 66 is located on the outer peripheral side of the inner peripheral portion 64a, a large clearance (clearance) can be secured between the planetary gear 12 and the coupling wall 66.

Furthermore, by performing the end mill machining from the inner peripheral portion 64a side of the 1 st fixing flange 64, the occurrence of thinning can be prevented.

As shown in fig. 13, the shaft diameter of the 1 st shaft fixing portion 121a of the planetary gear support shaft 121 supported by the 1 st fixing flange 64 is formed smaller than the shaft diameter of the other portion (shaft main body portion of reference numeral 121 c). The 1 st shaft fixing portion 121a is fixed by a press fastening portion 124 press-fastened to the 1 st fixing flange 64.

The 2 nd shaft fixing portion 121b supported by the other 2 nd fixing flange 65 is fixed in a state of being fitted into the 2 nd fixing flange 65. The 2 nd shaft fixing portion 121b of the planetary gear support shaft 121 is fixed to the 2 nd fixing flange 65 by slight press-fitting. Here, the light press-fitting generally refers to fitting with a considerable force required for assembly or disassembly, and is press-fitting for fixing with high accuracy.

An outer waterproof seal 67 is provided between an outer peripheral surface 63B of the carrier main body 63 of the 1 st support body 61 and an inner peripheral surface 45B of the case tube 45 of the motor case 44 on the 2 nd space 46B side.

In the electric reel 1 configured as described above, the motor can be driven by connecting the power supply line connected to the external power supply to the power supply connection portion. When the clutch mechanism 5 is in the clutch engaged state, the winding operation of the handle 20 is performed or the power lever (power lever) is operated to drive the motor 4, so that these driving forces are transmitted to the spool 3 through the reduction gear 10, and the spool 3 can be rotated to wind the fishing line. The rotational driving force of the motor 4 is reduced in speed by the plurality of planetary gears 12A, 12B, and 12C and transmitted to the spool 3.

On the other hand, when the clutch operating member 50 is operated to switch the clutch mechanism 5 to the clutch-disengaged state, the spool 3 can be switched to the spool-free (rotated) state to reel out the fishing line.

Next, in the reduction gear 10 of the electric reel 1, as a manufacturing method for assembling the planetary gear 12 to the carrier 6, as shown in fig. 5, three planetary gears 12A, 12B, and 12C are disposed between the 1 st fixing flange 64 and the 2 nd fixing flange 65 of the carrier 6, and then the rotation shaft holes of the planetary gears 12 are inserted through the planetary gear support shafts 121. As shown in fig. 13, the 2 nd shaft fixing portion 121b of the planetary gear support shaft 121 inserted into the rotation shaft hole is fixed to the 2 nd fixing flange 65 by slight press-fitting. At the same time, the 1 st shaft fixing portion 121a is press-fastened to the 1 st fixing flange 64 to form a press-fastening portion 124 for fixing. Accordingly, the planetary gear support shaft 121 is a both-end support structure fixed to the both fixing flanges 64 and 65.

Next, the speed reducer 10 of the electric reel 1, the method of manufacturing the speed reducer 10 of the electric reel 1, and the operation of the electric reel 1, which are configured as described above, will be described in detail with reference to the drawings.

As shown in fig. 4, in the speed reducer 10 of the electric reel 1 according to the present embodiment, both 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. 13, so that the deflection of the planetary gear support shaft 121 at the time of high load can be reduced, and the noise caused by the deflection can be suppressed.

Further, since the planetary gear support shaft 121 is fixed to the carrier 6 by being supported at both ends, it is not necessary to provide a flange member as a planetary gear retaining member on the planetary gear support shaft, as in the case of the conventional planetary gear supported by a cantilever type. Therefore, the shaft diameter of the planetary gear support shaft 121 can be reduced, and for example, a planetary gear having a smaller number of teeth can be selected, thereby increasing the degree of freedom in selecting the reduction ratio of the reduction gear transmission 10.

Further, by omitting the flange member, a space in which the bearing length of the planetary gear support shaft 121 can be increased can be secured. Therefore, the length of the bearing can be increased to stabilize the meshing state of the planetary gear 12.

In addition, in the present embodiment, since the planetary gear support shaft 121 can be made smaller in diameter than the conventional art as described above, the circumferential speed of the planetary gear 12 with respect to the support shaft can be reduced, thereby reducing the friction loss therebetween and further improving the rotational efficiency.

In the present embodiment, a step portion is formed between the 1 st shaft fixing portion 121a of the planetary gear support shaft 121 and the other shaft portion 121 c. With this stepped planetary gear support shaft 121, the 1 st shaft fixing portion 121a is press-fastened and the press-fastened portion 124 is locked in a state where the 2 nd shaft fixing portion 121b is fitted to the 2 nd fixing flange 65, whereby the planetary gear support shaft 121 is fixed in a state where it is prevented from falling off.

In this way, in the present embodiment, the planetary gear support shaft 121 can be fixed to the pair of fixed flanges 64 and 65 so as to be non-rotatable with respect to the pair of fixed flanges 64 and 65 by a simple shaft shape.

In the present embodiment, when the 1 st shaft fixing portion 121a of the planetary gear support shaft 121 is assembled before being fixed to the 1 st fixing flange 64 of the carrier 6 by press-fitting, the 2 nd shaft fixing portion 121b is fixed to the 2 nd fixing flange 65 by slight press-fitting, so that the planetary gear support shaft 121 can be prevented from coming off, and workability can be improved.

In the present embodiment, the motor case 44 is provided, the motor case 44 houses the motor 4, and has the partition wall 46 that rotatably supports the motor rotating shaft 41, the partition wall 46 is provided between the motor 4 and the sun gear 11, and the motor 4 is fixed to the partition wall 46, so that the contact area between the motor 4 and the motor case 44 can be increased, and heat generated during driving of the motor can be efficiently transmitted to the motor case 44 to radiate heat, as compared with a case where the motor rotating shaft 41 is fixed on the motor end cap 434 side of the motor case 44 (on the side opposite to the partition wall 46 with the motor 4 interposed therebetween).

In the present embodiment, compared to the case where the motor rotating shaft 41 is fixed to the motor end cap 434 side in the related art, the length (lever ratio) of the motor 4 in the assembled portion is reduced because the assembled portion of the motor 4 is located close to the sun gear 11. Therefore, compared to a fixing structure in which the motor rotary shaft 41 is fixed to the base end side of the motor end cap 434, the accuracy of the flatness of the assembled portion can be relaxed.

In the present embodiment, since the carrier 6 is configured to support the sun gear 11 or the motor rotary shaft 41 via the carrier bearing 14, the carrier bearing 14 can be made compact. Further, an increase in the length of the carrier 6 in the direction of the motor rotation shaft 41 for disposing the carrier bearing portion 14 can be suppressed. That is, the following can be suppressed: as in the case of performing the shaft support on the outer peripheral surface of the accommodating cylinder of the carrier, the dimension of the accommodating cylinder in the axial direction becomes longer as a large bearing is provided.

Further, the sun gear 11 or the motor rotary shaft 41 is supported by the carrier 6, so that the meshing accuracy of the sun gear 11 and the planetary gears 12 can be improved.

In the speed reducer of the electric reel, the method of manufacturing the speed reducer of the electric reel, and the electric reel for fishing according to the present embodiment configured as described above, the efficiency of the speed reducer 10 can be improved by suppressing the deflection of the planetary gear 12 to improve the rotation efficiency.

(modification 1)

Next, the 2 nd carrier 6B of the reduction gear of the electric reel according to the 1 st modification is specifically shown with reference to fig. 14 to 17. The 2 nd carrier 6B supports the planetary gear support shaft 121 of the three planetary gears 12A, 12B, 12C, as in the above embodiment.

In the 2 nd carrier 6B, the pair of fixing flanges 64A, 65A are divided. The 1 st fixing flange 64A (1 st fixing plate) and the 2 nd fixing flange 65A (2 nd fixing plate) are disposed coaxially with each other and in a state of being separated in the axial direction, and are coupled by a plurality of (three in this case) 1 st link shafts 68A.

In the following description, a central axis common to the 1 st and 2 nd fixing flanges 64A and 65A is referred to as a carrier axis C3. In the carrier shaft C3, the 2 nd fixing flange 65A side is defined as a lower side and a lower side, and the 1 st fixing flange 64A side is defined as an upper side and an upper side.

As shown in fig. 16 and 17, the fixing flanges 64A, 65A have 1 st through holes 64c, 65c into which the planetary gear support shafts 121 are respectively fitted, and 2 nd through holes 64d, 65d into which the end portion 68a of the link shaft 68 is fitted. Further, a 3 rd through hole 64e for fitting the 1 st support body 61 is provided in the center portion of the 1 st fixing flange 64A. The 3 rd through hole 64e is formed with a toothed surface that engages with the 1 st support body 61.

The 2 nd carrier 6B is configured such that the connecting wall 66 (see fig. 9 to 12) of the above embodiment is omitted and the 1 st link shaft 68A is provided instead.

The 1 st link shaft 68A is disposed at a position not interfering with the planetary gears 12A, 12B, 12C between the planetary gears 12A, 12B, 12C adjacent to each other in the circumferential direction around the carrier shaft C3. The link shaft 68A has a shaft diameter dimension such that the diameter of both end portions (upper end portion 68A, lower end portion 68b) in the direction of the carrier shaft C3 is smaller than the diameter of the central portion 68C. Both end portions 68A, 68b of the 1 st link shaft 68A are press-fastened in a state of being fitted into the 2 nd through holes 64d, 65d of the fixing flanges 64A, 65A. The 2 nd through holes 64d, 65d are provided with inner diameters substantially equal to the diameters of the both end portions 68A, 68b of the 1 st link shaft 68A. Therefore, after the 1 st link shaft 68A is press-fastened, the fixing flanges 64, 65 are positioned in the carrier shaft C3 direction.

Next, a manufacturing method of assembling the planetary gears 12 in the 2 nd carrier 6B of the reduction gear transmission 10 according to the 1 st modification will be described.

As shown in fig. 17, first, three planetary gears 12A, 12B, 12C are disposed on the 2 nd fixing flange 65A, and three 1 st link shafts 68A are disposed. At this time, the lower end portion 121d of the planetary gear support shaft 121 is inserted into the 2 nd through hole 65d of the 2 nd fixing flange 65A, and the lower end portion 68b of the 1 st link shaft 68A is inserted into the 2 nd through hole 65 d. Next, the 2 nd fixing flange 65A is disposed so as to face the 1 st fixing flange 64A. At this time, the planetary gear support shaft 121 is inserted into the 2 nd through hole 64d of the 1 st fixing flange 64A, and the upper end portion 68A of the 1 st link shaft 68A is inserted into the 1 st through hole 64 c.

Then, the 1 st link shaft 68A is fixed to the pair of fixed flanges 64A, 65A and the three planetary gears 12A, 12B, 12C are also fixed by press-fastening the upper end portion 68A and the lower end portion 68B of the 1 st link shaft 68A from the respective fixed flanges 64A, 65A outside in the carrier shaft C3 direction. Here, reference symbol R in fig. 14 to 16 denotes a press-fastening portion.

In the carrier 6B according to the modification 1, the 1 st fixing flange 64A and the 2 nd fixing flange 65A can be fixed by the 1 st link shaft 68A by press fastening, and therefore, it is possible to omit the manufacturing time and effort required to fix the connecting wall 66 to the 1 st fixing flange 64A by T-groove machining or end mill machining as in the above-described embodiment shown in fig. 10.

(modification 2)

Next, the 3 rd carrier 6C according to the 2 nd modification shown in fig. 18 and 19 is configured in a shape in which the 2 nd link shaft 68B is used instead of the 1 st link shaft 68A of the 1 st modification.

The 2 nd link shaft 68B has an upper end portion 68d formed to have the same diameter as the central portion 68c, and a flange portion 681 formed radially outward from the entire outer peripheral edge of the 2 nd link shaft 68B. The lower end portion 68B of the 2 nd link shaft 68B is formed to have a smaller diameter than the central portion 68 c. A through hole 64f through which the upper end portion 68d of the 2 nd link shaft 68B can be inserted is formed in the 1 st fixing flange 64A, and a step portion 64g that engages with the flange portion 681 is formed on the inner peripheral edge on the outer side of the through hole 64 f. A through hole 65e through which the lower end portion 68B of the 2 nd link shaft 68B can be inserted is formed in the 2 nd fixing flange 65A.

In the 2 nd modification, only the lower end portion 68B of the 2 nd link shaft 68B is press-fastened from the outside in the direction of the carrier shaft C3 to form the press-fastened portion R. Accordingly, the 1 st and 2 nd fixing flanges 64A, 65A are fixed by the 2 nd link shaft 68B, and the three planetary gears 12A, 12B, 12C are also fixed.

In the present modification 2, the flange portion 681 is provided on one side of the 2 nd link shaft 68B, and the flange portion 681 is engaged with the stepped portion 64g, whereby the pair of fixing flanges 64A, 65A can be fixed by the 2 nd link shaft 68B only by pressing and fastening the upper end portion 68d of the 2 nd link shaft 68B. Therefore, as compared with the case of the above-described modification 1 in which both sides of the 2 nd link shaft 68B are press-fastened, the press-fastening can be performed more efficiently and easily, and the work time can be reduced.

Further, in the 2 nd modification example, the flange portion 681 is provided at the upper end portion 68d of the 2 nd link shaft 68B, but the present invention is not limited thereto, and a projection portion that projects radially outward may be provided at a part of the upper end portion 68d of the 2 nd link shaft 68B in the circumferential direction.

In the 2 nd link shaft 68B, the position of the flange 681 is not limited to the upper end 68d, and the flange may be provided at the lower end 68B.

(modification 3)

Next, in a modification 3 shown in fig. 20, when the planetary gear 12 is supported between the 1 st and 2 nd fixing flanges 64A, 65A, the support shaft (press-fastened support shaft 126) of the planetary gear 12 is press-fastened together with the pair of fixing flanges 64A, 65A to form a press-fastened portion R.

The 1 st shaft portion 126A, the 2 nd shaft portion 126B, and the protruding ring portion 126C in the press-fastening support shaft 126 are integrally provided. The 1 st shaft part 126A and the 2 nd shaft part 126B are coaxially arranged by the protruding ring part 126C. The 1 st shaft part 126A is inserted and fixed into the bearing 125 of the planetary gear 12. The 2 nd shaft portion 126B has a smaller diameter than the 1 st shaft portion 126A, and the upper end portion 126A and the lower end portion 126B of the press-fastening support shaft 126 are press-fastened in a state where the 2 nd shaft portion 126B is inserted into the 2 nd through holes 64d, 65d of the fixing flanges 64A, 65A. The protruding ring portion 126C is formed to have a larger diameter than the shaft diameter of the 1 st shaft portion 126A.

In the press-fastening support shaft 126, when the 1 st shaft portion is inserted into the bearing 125 and the lower end surface 126C of the projecting ring portion 126C is in contact with the upper end 125A of the bearing 125, the lower end portion 126b of the 1 st shaft portion 126A is in a state of projecting downward from the 2 nd fixing flange 65A. When the 2 nd shaft portion 126B is inserted into the 2 nd through hole 65d of the 1 st fixing flange 64A and the 1 st fixing flange 64A is brought into contact with the upper end surface 126d of the projecting ring portion 126C, the upper end portion 126a of the 2 nd shaft portion 126B projects upward from the 1 st fixing flange 64A. Then, the end portions 126a and 126b protruding from the fixing flanges 64A and 65A are pressed and fastened.

Accordingly, the planetary gear 12 is fixed to the pair of fixing flanges 64A, 65A by press-fastening the support shaft 126. In this case, since the contact area between the projecting ring portion 126C and the upper end 125a of the bearing 125 and the 1 st fixing flange 64A can be increased, the press-fastening and the dropping-out can be suppressed.

The present invention is not limited to the embodiment described above, but can be applied to any type of fishing reel, such as a fishing reel, and a fishing reel. The embodiments may be implemented in other various manners, and various omissions, substitutions, and changes may be made without departing from the spirit of the invention. The embodiments and modifications thereof include, for example, technical means that can be easily conceived by those skilled in the art, substantially the same technical means, and technical means that are the same in scope.

For example, in the above embodiment, the reduction gear 10 directly connected to the motor rotating shaft 41 of the motor 4 is used as the target, but the reduction gear 10 is not limited to the one provided in the motor 4. For example, the reduction gear for the spool may be directly connected to the spool rotation shaft. That is, a sun gear may be fixed to an end of the spool rotation shaft, a plurality of planetary gears may be provided to mesh with the sun gear, and a carrier may be provided to rotate together with the planetary gears around a ring gear, and the carrier may transmit a rotational driving force from the speed reducer 10 of the motor 4. In this case, the rotational driving force of the motor 4 is transmitted to the reduction gear for the spool through the reduction gear 10, and is reduced in speed by the reduction gear for the spool to rotate the spool 3.

In the present embodiment, the carrier 6 is configured to have the pair of opposing fixed flanges 64 and 65 on both sides of the planetary gear support shaft 121 in the axial direction, but the present invention is not limited to this configuration.

In the present embodiment, the 1 st shaft fixing portion 121a of the planetary gear support shaft 121 is fixed to the 1 st fixing flange 64 by the press fastening portion 124, but the present invention is not limited to a fixing mechanism by press fastening, and may be a mechanical coupling structure such as fitting. In the present embodiment, the 2 nd shaft fixing portion 121b of the 2 nd fixing flange 65 supported by the planetary gear support shaft 121 is fixed in a state of being fitted by slight press-fitting, but another fixing mechanism such as interference fitting may be employed.

In the present embodiment, the partition wall 46 of the motor case 44 is fixed to the case 43 of the motor 4 by the fixing screws 47 as a method of fixing the motor 4 and the motor case 44, but the method is not limited to the fixing method using the fixing screws, and other fixing means may be employed. The fixing position is not limited to the partition wall 46 and the case 43, and the fixing position and the number of fixing portions may be set as appropriate.

The number, arrangement, and other configurations of the planetary gears can be set arbitrarily.
