Description

ELECTRICAL FISHING REEL

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric reel, and more particularly to an electric reel having a reduction mechanism including a plurality of planetary gear mechanisms.

The electric reel has a motor disposed inside the spool or in front of the spool, and the rotation of the motor is decelerated by the deceleration mechanism and transmitted to the spool. For example, in the motor-driven reel disclosed in Patent Document 1, a motor is disposed inside a spool, and a deceleration mechanism is disposed coaxially with the output shaft of the motor. The deceleration mechanism has two planetary gear mechanisms. These planetary gear mechanisms have a sun gear, a plurality of planet gears that the sun gear engages, a carrier that supports the planet gears, and a ring gear that meshes the planet gears.

In the deceleration mechanism of the electric reel such as the above (or above), the first sun gear of the first planetary gear mechanism is fixed to the output shaft of the motor. The first carrier of the first-stage planetary gear mechanism is connected to the second sun gear of the second-stage planetary gear mechanism, and the second sun gear is rotatably supported by the output shaft of the motor. Further, the planetary gears of the two planetary gear mechanisms are engaged with one ring gear, and the ring gear is fixed to the spool. In addition, the ring gear may be integrally formed with the spool.

Japanese Patent Application Laid-Open No. 2010-29145

As described above, most of the deceleration mechanism of the electric reel has the planetary gear mechanism for realizing the necessary reduction ratio. In particular, the width of engaging (engaging) of the respective toothed wheels in the direction of the rotation axis of the motor is narrowed in order to miniaturize the deceleration mechanism and further to miniaturize the electric reel itself.

Further, in the conventional electric reel as described above, two planetary gear mechanisms are provided in order to realize a required reduction ratio. The first carrier of the first planetary gear mechanism and the second sun gear of the second planetary gear mechanism are connected. More specifically, the inner circumferential portion of the first carrier formed in a cylindrical shape is engaged with the outer circumference of the second sun gear, and the first carrier and the second sun gear are engaged with each other by caulking so that they are prevented from moving axially separately from each other, thereby making the planetary gear mechanism smaller.

In the deceleration mechanism as described above, since the rotation load from the motor and the rotational load from the handle are applied, the deceleration mechanism is shifted in the direction of the rotation axis of the motor by long-term use or the like and the engagement of the toothed wheels is released I can think.

Particularly, in the conventional electric reel as described above, it can be considered that the caulking fixation of the first carrier and the second sun gear is released. When the caulking is released so that the first carrier is far away from the second sun gear in the axial direction, the two are disengaged from each other and the rotation is not transmitted, so that the first carrier does not function as the deceleration mechanism.

An object of the present invention is to prevent the deceleration mechanism from being displaced in the axial direction so that the deceleration mechanism functions as a deceleration mechanism even when the engagement of the toothed wheels is released. More specifically, the present invention is intended to function as a deceleration mechanism even when the carrier of the first planetary gear mechanism and the sun gear of the second planetary gear mechanism are released from caulking.

An electric reel according to a first aspect of the present invention includes a reel body, a spool rotatably supported on the reel body, a motor accommodated in the spool and driving the spool, a deceleration mechanism And a movement regulating mechanism for regulating the movement of the deceleration mechanism in the rotation axis direction.

In this electric reel, the rotation of the motor is transmitted to the spool through the deceleration mechanism. Here, when the deceleration mechanism is moved in the direction of the rotation axis for some reason, for example, engagement of the teeth or the like in the deceleration mechanism is released, so that the deceleration mechanism may not function.

Therefore, in the electric reel of the present invention, the movement regulating mechanism restricts the movement of the deceleration mechanism in the direction of the rotation axis. Therefore, the function of the deceleration mechanism is prevented from being damaged.

In the electric reel according to the second aspect of the present invention, in the electric reel of the first aspect, the movement regulating mechanism has the regulating body portion provided on the inner wall of the spool.

Here, the restriction body provided on the inner wall of the spool restricts the movement of the reduction mechanism in the direction of the rotation axis. Therefore, the movement of the deceleration mechanism in the direction of the rotation axis can be restricted by a simple structure.

In the electric reel according to the third aspect of the present invention, in the electric reel of the second side, the movement regulating mechanism further has a protrusion protruding from the regulating body in the direction of the rotational axis.

Here, the movement of the deceleration mechanism in the direction of the rotation axis is restricted by the projections provided on the restriction body. Therefore, similarly to the above, in addition to being capable of restricting the movement of the deceleration mechanism in the direction of the rotation axis by a simple structure, it is possible to improve the degree of freedom of installation of the regulation body provided on the inner wall of the spool.

The electric reel according to the fourth aspect of the present invention is the electric reel of the second or third aspect, wherein the regulating body portion is a partition wall partitioning the space where the motor is disposed and the space where the speed reducing mechanism is disposed.

In this case, not only the conventional configuration can be used without installing a new configuration, but the projection in the direction of the rotation axis of the deceleration mechanism can be regulated by a simpler structure by providing the projection.

An electric reel according to a fifth aspect of the present invention is the electric reel of any one of the first to fourth aspects, wherein the deceleration mechanism has a first planetary gear mechanism. The first planetary gear mechanism includes a first sun gear fixed to a shaft of the motor, a plurality of first planetary gears meshing with the first sun gear, a first carrier rotatably supporting the first planetary gear, And a first ring gear which meshes with the first planetary gear while rotating synchronously with the spool.

Here, the rotation of the motor is transmitted to the spool through the first planetary gear mechanism as the deceleration mechanism.

An electric reel according to a sixth aspect of the present invention is the electric reel of the fifth aspect, wherein the deceleration mechanism further includes a second planetary gear mechanism. The second planetary gear mechanism includes a second sun gear rotatably supported on a shaft of the motor and rotating in synchronization with the first carrier, a plurality of second planetary gears meshing with the second sun gear, A second carrier for rotatably supporting the planetary gear, and a second ring gear which meshes with the second planetary gear while rotating in synchronism with the spool.

Here, the rotation of the motor is transmitted to the first planetary gear mechanism and further to the second planetary gear mechanism via the first carrier of the first planetary gear mechanism. And the reduced rotation from the ring gears of these planetary gear mechanisms is transmitted to the spool.

Here, there may be a problem in a configuration (for example, caulking fixation) for restricting axial movement between the first carrier and the second sun gear for some reason.

Therefore, in the electric reel of the present invention, the movement restricting mechanism is provided, and the movement of the speed reducing mechanism, specifically, the first carrier to the motor side is regulated. Thus, the meshing of the first carrier and the second sun gear is maintained, and the rotation of the first carrier and the second sun gear is synchronized with each other.

In the electric reel according to the seventh aspect of the present invention, in the electric reel of the sixth aspect, the first carrier is formed in an annular shape and has an engagement portion at an inner peripheral end portion thereof. The second sun gear has a portion to be engaged which is engaged with the engagement portion of the first carrier on the outer peripheral portion. And the first carrier and the second sun gear are not relatively rotatable.

In the electric reel according to the eighth aspect of the present invention, in the electric reel of the seventh aspect, the engaging portion of the first carrier has a plurality of engaging teeth. The engaged portion of the second sun gear has a plurality of engaged teeth that are engaged with the engagement teeth of the first carrier. The engaging teeth and the engaging teeth are caulked and fixed to each other.

Here, even if the first carrier and the second sun gear are released from caulking, the first carrier is restricted from moving in the axial direction by the movement regulating mechanism. Therefore, the disengagement of the two is prevented, and the rotation of the first carrier and the second sun gear is synchronized with each other.

In the electric reel according to the ninth aspect of the present invention, in the electric reel of any of the fifth to eighth aspects, the movement regulating mechanism includes a first regulating mechanism for regulating the movement of the speed reducing mechanism in the rotational axis direction of the first carrier And has a carrier movement regulating member.

Here, similarly to the above, even when the first carrier and the second sun gear are released from caulking, the first carrier is restricted from moving in the axial direction by the first carrier movement restricting member, do.

An electric reel according to a tenth aspect of the present invention is the electric reel of any of the sixth to ninth aspects, wherein the deceleration mechanism further includes a third planetary gear mechanism. The third planetary gear mechanism includes a third sun gear rotatably supported on a shaft of the motor and rotating in synchronization with the second carrier, a plurality of third planetary gears meshing with the third sun gear, A third carrier for rotatably supporting the planetary gear, and a third ring gear which meshes with the third planetary gear while rotating in synchronism with the spool.

Here, the rotation of the motor is transmitted to the spool through the first, second and third planetary gear mechanisms.

In the electric reel according to the eleventh aspect of the present invention, in the electric reel of the tenth aspect, the movement regulating mechanism further includes a second carrier movement regulating member for regulating the movement of the second carrier in the rotational axis direction, Lt; / RTI >

Here, the movement of the second carrier in the direction of the rotation axis is restricted by the second carrier movement restricting member. Thus, the engagement of the second carrier and the third sun gear is prevented from being released.

According to the present invention as described above, since the movement of the deceleration mechanism in the direction of the rotation axis is restricted by the movement regulating mechanism, the function of the deceleration mechanism is prevented from being damaged. For example, even if the carrier of the first-stage planetary gear mechanism and the sun gear of the second-stage planetary gear mechanism are fixed by caulking or the like, they can function as a deceleration mechanism.

&Lt; Drag mechanism 35 and clutch mechanism 37 >

As shown in Fig. The drag mechanism 35 is composed of a plurality of friction plates and intermediate plates which are non-rotatably connected to either one of the handle shaft 34 and the main gear 47 and plate springs for pressing these plates have. And it is possible to change the drag force by adjusting the star drag 49.

The pinion gear 36 meshes with the main gear 47. The pinion gear 36 is rotatably supported around a support shaft 50 supported by the second side cover 12. [ The clutch mechanism 37 switches the spool 4 between a rolled state and a free state, and when the clutch is off, the clutch mechanism 37 is in a free state, and the fishing line can be released. Further, when the clutch is turned on, it is in a hoisting state, and the hoisting operation can be performed by the motor (5) or the handle (2). The clutch mechanism 37 is constituted by one end of the pinion gear 36 and one end of the normal shaft 42ca of the second carrier 42c. When the pinion gear 36 is moved in the direction away from the normal shaft 42ca, the clutch is released (clutch off). By moving the pinion gear 36 in the opposite direction, the clutch is engaged (Clutch ON). In addition, the clutch mechanism 37 can turn the clutch on / off by a clutch operation mechanism (not shown).

[action]

First, when the motor 5 is rotated with the clutch mechanism 37 engaged (clutch-on), the first sun gear 41s rotates together with the output shaft 28. [ This causes the first planetary gear 41p engaged with the first sun gear 41s and the ring gear Rg to revolve together with the first carrier 41c. Since the first carrier 41c and the second sun gear 42s are connected to each other, the second sun gear 42s also rotates in the same direction. Here, the second carrier 42c is connected to the handle shaft 34 by the clutch mechanism 37, and the handle shaft 34 is inhibited from being reversed by the ratchet. Therefore, the second carrier 42c 42c are in a state in which idle is prohibited. Accordingly, when the second sun gear 42s rotates, the second planetary gear 42p rotates and rotates the spool 4 in a direction opposite to the rotation direction of the motor 5.

The rotation of the handle 2 is transmitted to the pinion gear 36 through the drag mechanism 35 when the clutch mechanism 37 rotates the handle 2 in a connected state (clutch-on state). At this time, since the output shaft 28 of the motor 5 is inhibited from reversing by the one-way clutch 32, the first sun gear 41s does not rotate. In this state, when the rotation is transmitted to the pinion gear 36 by the handle 2, the second carrier 42c revolves so that the second planetary gear 42p rotates while revolving and rotates the spool 4 .

During the above-described operation, the caulking of the first carrier 41c and the second sun gear 42s may be released. Since the first carrier 41c and the second sun gear 42s are engaged with each other by the plurality of teeth 41t and 42t as described above, even when the caulking is released and the two are shifted to some extent in the axial direction, The rotation is transmitted. However, when the moving distance of the both in the axial direction becomes large, the meshing of each other is released, and the rotation is not transmitted.

This reel is provided with a carrier movement regulating member 43 for regulating the movement of the first carrier 41c to the side of the motor 5 so that the movement of the first carrier 41c in the axial direction Distance is suppressed. Specifically, when the first carrier 41c moves to the motor 5 side, the support pin 41m of the first carrier 41c is supported by the carrier movement regulating member 43 fixed to the side surface of the partition plate 45, And the movement of the first carrier 41c toward the motor 5 side is regulated. Therefore, engagement of the first carrier 41c and the second sun gear 42s can be prevented from being released, and the function of the deceleration mechanism 6 is not impaired.

When the first carrier 41c comes into contact with the carrier movement restricting member 43, the carrier movement restricting member 43 and the support pin 41m come into contact with each other, The braking force does not act on the rotation of the wheels 41p.

Even in this example, even if the first carrier 41c and the second sun gear 42s are released from caulking and the first carrier 41c moves toward the motor 5 side, the first carrier 41c The side of the first planetary gear 41p comes in contact with the large diameter portion 43 'of the first sun gear 41s' so that the movement of the first carrier 41c toward the motor 5 side can be regulated .

(c) In the above embodiment, the movement of the first carrier 41c is restricted by abutting the carrier movement restricting member 43 against the support pin 41m. However, for example, the first carrier may be provided with a first It is also possible to arrange the engaging portion and arrange the second engaging portion opposed to the first engaging portion in the axial direction in the spool and restrict the movement of the first carrier in the axial direction by bringing these engaging portions into contact with each other It is acceptable.

(d) Fig. 8 shows another example of the deceleration mechanism. 8 includes a first planetary gear mechanism 61, a second planetary gear mechanism 62, and a third planetary gear mechanism 63. The speed change mechanism 60 includes a first planetary gear mechanism 61, a second planetary gear mechanism 62, The configuration of the first planetary gear mechanism 61 is the same as that shown in Figs. 3 and 4, and a detailed description thereof will be omitted. The configuration other than the deceleration mechanism is completely the same as the configuration shown in Figs. 3 and 4, including the configuration for restricting the axial movement of the first carrier.

The second planetary gear mechanism 62 of the second planetary gear mechanism 62 is different from that shown in Figs. 3 and 4 only in the second carrier 62c, and the other structures are the same. The second carrier 62c of the second planetary gear mechanism 62 is formed in an ordinary manner and formed in an annular shape and has a plurality of teeth 62t similar to those of the above embodiment at its inner peripheral end.

The third planetary gear mechanism 63 includes a third sun gear 63s, a plurality of third planetary gears 63p, a third carrier 63c and a ring gear Rg Common with the ring gear of the planetary gear mechanism). The third sun gear 63s is rotatably supported on the output shaft 28 of the motor 5. [ A plurality of teeth 63t are formed at the end of the outer peripheral surface of the third sun gear 63s on the motor side and the teeth 63t are engaged with the teeth 62t formed on the inner peripheral end of the second carrier 62c have. Further, the second carrier 62c and the third sun gear 63s are caulked and fixed, and are prevented from moving independently in the axial direction. Each of the plurality of third planetary gears 63p meshes with the third sun gear 63s and the ring gear Rg and is supported by the support pin 63m in the same manner as the other planetary gear mechanisms 61, And is rotatably supported by the third carrier 63c. The third carrier 63c has a normal shaft 63ca extending axially outward (on the side away from the motor) at its inner peripheral portion. The tip of the normal shaft 63ca is connected to the pinion gear 36 have.

(e) Another embodiment is shown in Fig. In the example shown in Fig. 9, the basic configuration is the same as the example shown in Fig. 9 has a first planetary gear mechanism 61, a second planetary gear mechanism 62, and a third planetary gear mechanism 63. The speed change mechanism of the embodiment shown in Fig. The configuration of each of the planetary gear mechanisms 61 to 63 is the same as that shown in Fig. 8 except for the dimension in the axial direction (width). In this example, not only the engagement of the first carrier 61c and the second sun gear 62s but also the engagement of the second carrier 62c and the third sun gear 63s are engaged, There is a possibility.

Thus, in the example shown in Fig. 9, a portion 65 having a larger diameter than the other outer peripheral surface is provided on the end of the outer surface of the second sun gear 62s on the side of the motor 5, Thereby restricting the second carrier 62c from moving to the motor side. Even in this example, even when the second carrier 62c and the third sun gear 63s are released from caulking and the second carrier 62c moves toward the motor 5 side, the second carrier 62c The side surface of the second planetary gear 62p comes into contact with the large diameter portion 65 of the second sun gear 62s so that the movement of the second carrier 62c toward the motor 5 side can be regulated. Therefore, the engagement between the second carrier 62c and the third sun gear 63s is maintained, and the function as the deceleration mechanism is not impaired.

Incidentally, in the embodiment shown in Fig. 9, the carrier movement regulating member 43 for regulating the axial movement of the first carrier 61c may be omitted depending on the arrangement of the respective members.
