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.

In the electric reel, a motor is disposed inside the reel or in front of the reel, and the rotation of the motor is transmitted to the reel by a speed reduction mechanism.

As described above, the speed reduction mechanism of the electric reel has a planetary gear mechanism in order to achieve a desired reduction ratio. Further, in order to achieve downsizing of the speed reduction mechanism, the size of the electric reel itself is reduced, and the meshing (engagement) width of each of the gears in the rotation axis direction of the motor is narrowed.

Further, in the conventional electric reel as described above, in order to achieve the required reduction ratio, there are two planetary gear mechanisms. Further, the first pinion carrier of the planetary gear mechanism of the first stage and the second sun gear of the planetary gear mechanism of the second stage are coupled. More specifically, the inner peripheral portion of the cylindrical first pinion carrier is engaged with the outer circumference of the second sun gear, and the first pinion carrier and the second sun gear are pseudo-fixed to each other so as to be different from each other. The planetary gear mechanism is miniaturized without moving in the axial direction.

Since the rotational load from the motor and the rotational load from the operating lever are applied to the above-described speed reduction mechanism, the speed reduction mechanism such as long-term use will deviate in the direction of the rotation axis of the motor, and the engagement of the respective gears will be released.

In particular, in the conventional electric reel as in the foregoing, The false fixing of the first pinion bracket and the second sun gear is released. When the first pinion holder is largely moved away from the second sun gear in the axial direction, the engagement between the two is removed, and the rotation cannot be transmitted, so that the first pinion holder cannot function as a speed reduction mechanism.

An object of the present invention is to prevent the deceleration mechanism from deviating in the axial direction and to function as a speed reduction mechanism even if the engagement of the gears is disengaged. Specifically, even if the pinion bracket of the planetary gear mechanism of the first stage and the sun gear of the second stage planetary gear mechanism are detached, the function of the speed reduction mechanism is provided.

An electric reel according to a first aspect of the present invention includes a reel body and a reel rotatably supported by the reel body, a motor that is housed inside the reel to drive the reel, and a motor The rotation is transmitted to the reduction mechanism of the reel and the movement restriction mechanism that restricts the movement of the reduction mechanism in the direction of the rotation axis.

In this electric reel, the rotation of the motor is transmitted to the reel through the speed reduction mechanism. When the speed reduction mechanism is moved in the direction of the rotation axis by any reason, for example, the meshing of the teeth in the speed reduction mechanism may be disengaged, and the function of the speed reduction mechanism may not be provided.

Here, in the electric reel of the present invention, the movement of the speed reduction mechanism in the direction of the rotation axis is restricted by the movement restriction mechanism. Therefore, the function of the speed reduction mechanism can be prevented from being impaired.

The electric reel according to the second invention of the present invention is as the first In the electric reel of the invention, the movement restricting mechanism has a restricting body portion provided on the inner wall of the reel.

Here, the movement of the speed reduction mechanism in the direction of the rotation axis is restricted by the restriction main body portion provided on the inner wall of the spool. Therefore, the movement of the speed reduction mechanism in the direction of the rotation axis can be restricted by a simple configuration.

An electric reel according to a third aspect of the invention is the electric reel according to the second aspect of the invention, wherein the movement restricting mechanism further has a projection protruding from the restricting main body toward the rotation axis.

Here, the movement of the speed reduction mechanism in the rotation axis direction is restricted by the protrusion provided in the restriction main body portion. Therefore, similarly to the above, the movement of the speed reduction mechanism in the direction of the rotation axis can be restricted by a simple configuration, and the degree of freedom in providing the restriction of the main body portion provided on the inner wall of the spool can be improved.

The electric reel according to the fourth aspect of the present invention is the electric reel according to the second or third aspect of the invention, and the main body portion is a partition wall that partitions a space in which the motor is disposed and a space in which the speed reduction mechanism is disposed.

Here, it is not necessary to provide a new configuration, and it is possible to limit the movement of the speed reduction mechanism in the direction of the rotation axis by a simpler configuration by providing a conventional structure.

An electric reel according to a fifth aspect of the invention is the electric reel according to any one of the first to fourth invention, wherein the reduction mechanism has a first planetary gear mechanism. The first planetary gear mechanism includes a first sun gear that is fixed to a shaft of the motor, a plurality of first planetary gears that mesh with the first sun gear, and a first rotatably supported first planetary gear. A pinion bracket and a first ring gear that rotates in synchronization with the spool and meshes with the first planetary gear.

Here, the rotation of the motor is transmitted to the reel through the first planetary gear mechanism as the speed reduction mechanism.

An electric reel according to a sixth aspect of the invention is the electric reel according to the fifth aspect of the invention, wherein the reduction mechanism further includes a second planetary gear mechanism. The second planetary gear mechanism includes a second sun gear that is rotatably supported by the motor shaft and rotates in synchronization with the first pinion carrier, and a plurality of second planetary gears that mesh with the second sun gear, and The second pinion carrier rotatably supported by the second planetary gear and the second ring gear that rotates in synchronization with the spool and meshes with the second planetary gear.

Here, the rotation of the motor is transmitted to the first planetary gear mechanism, and the first pinion carrier that is further transmitted through the first planetary gear mechanism is transmitted to the second planetary gear mechanism. Moreover, the rotation from which the ring gear of the planetary gear mechanism is decelerated is transmitted to the reel.

Here, there is a case where a configuration (for example, a dummy fixing) for restricting the axial movement between the first pinion carrier and the second sun gear is problematic for any reason.

Here, in the electric reel of the present invention, the movement restricting mechanism is provided such that the movement toward the speed reduction mechanism, specifically, the motor side of the first pinion holder is restricted. Therefore, the meshing of the first pinion carrier and the second sun gear is maintained, and the rotation of the first pinion carrier and the second sun gear is synchronized.

Further, the engaged portion of the second sun gear is a plurality of engaged teeth that mesh with the engaging teeth of the first pinion carrier. Moreover, the engaging teeth and the engaged teeth are fixed to each other.

Here, even if the dummy fixing of the first pinion carrier and the second sun gear is disengaged, the movement of the first pinion holder in the axial direction by the movement restricting mechanism is restricted. Therefore, the engagement between the two is prevented from being disengaged, and the rotation of the first pinion carrier and the second sun gear can be synchronized.

Here, in the same manner as described above, even if the dummy fixing of the first pinion carrier and the second sun gear is disengaged, the first pinion holder movement restricting member moves the first pinion holder in the axial direction to be restricted, thereby preventing both of them. The snap is disengaged.

An electric reel according to a tenth aspect of the invention is the electric reel according to the sixth to ninth aspects of the invention, wherein the reduction mechanism further includes a third planetary gear mechanism. The third planetary gear mechanism has: rotatably and freely a third sun gear that is supported by the shaft of the motor and rotates in synchronization with the second pinion carrier, and a plurality of third planetary gears that mesh with the third sun gear, and a third small one that rotatably supports the third planetary gear a gear carrier and a third ring gear that rotates in synchronization with the reel and meshes with the third planetary gear.

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

The electric reel according to the eleventh aspect of the present invention is the electric reel according to the tenth aspect of the invention, the movement restricting mechanism, and the second small movement for restricting the movement of the second pinion holder of the speed reduction mechanism in the rotation axis direction. The gear carrier moves the restriction member.

Here, the movement of the second pinion holder movement restricting member toward the rotation axis direction of the second pinion holder is restricted. Therefore, the engagement of the second pinion carrier and the third sun gear is prevented from being disengaged.

For example, the fixing by the false gear fixing between the pinion bracket of the planetary gear mechanism of the first stage and the sun gear of the second planetary gear mechanism can function as a speed reduction mechanism even if it is disengaged.

The pinion holder movement restricting member 43 is an annular member and is provided at a position facing the support pin 41m of the first planetary gear mechanism 41 in the axial direction.

<Traction mechanism 35 and clutch mechanism 37>

As shown in FIG. 3, the traction mechanism 35 has a main gear 47 and a clutch portion 48 housed in the main gear 47. The traction mechanism 35 is composed of a plurality of friction plates and intermediate plates that are non-rotatably coupled to one of the handle shaft 34 and the main gear 47, and a disk spring that presses the plates. Moreover, the traction force can be changed by adjusting the star tractor 49.

The pinion gear 36 is meshed with the main gear 47. The pinion gear 36 is rotatably supported around the support shaft 50 supported by the second side cover 12. The clutch mechanism 37 is configured to switch the reel 4 to the rolled-up state and the free state. When the clutch is turned off (OFF), the clutch mechanism 37 is in a free state, and the fishing line can be discharged. And, when the clutch is engaged (ON), it becomes rolled up. In the state, the winding operation by the motor 5 or the operating lever 2 can be performed. The clutch mechanism 37 is constituted by one end of the pinion gear 36 and one end of the cylindrical shaft 42ca of the second pinion holder 42c. The opposite end portions of these are engageable with each other, and when the pinion gear 36 is moved away from the cylindrical shaft 42ca, the clutch is released (the clutch is OFF), and is moved in the opposite direction. The clutch is in a connected state (clutch engagement (ON)). Further, the clutch mechanism 37 can be turned ON/OFF by a clutch operating mechanism (not shown).

[action]

First, when the clutch mechanism 37 rotates the motor 5 in a state of being connected (clutch engaged), the first sun gear 41s rotates together with the output shaft 28. Thereby, the first planetary gear 41p in which the first sun gear 41s and the ring gear Rg mesh is revolved together with the first pinion bracket 41c. Further, since the first pinion bracket 41c and the second sun gear 42s are coupled, the second sun gear 42s also rotates in the same direction. Here, since the second pinion holder 42c is coupled to the handle shaft 34 by the clutch mechanism 37, and the handle shaft 34 is reversely prohibited by the ratchet, the second pinion holder 42c is in a state in which the revolution is prohibited. Therefore, when the second sun gear 42s rotates, the second planetary gear 42p rotates and rotates the reel 4 in the opposite direction to the rotation direction of the motor 5.

And the clutch mechanism 37 rotates the operating lever 2 in a state of being connected (clutch engaged), and the rotation of the operating lever 2 The rotation is transmitted to the pinion gear 36 through the traction mechanism 35. At this time, since the output shaft 28 of the motor 5 is reversely prohibited 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 operation lever 2, the second pinion holder 42c revolves, whereby the second planetary gear 42p rotates while rotating the reel 4 while revolving.

In the above operation, the dummy fixing of the first pinion bracket 41c and the second sun gear 42s is released. As described above, since the first pinion bracket 41c and the second sun gear 42s are meshed with each other by the plurality of teeth 41t and 42t, the rotation can be transmitted even if the dummy fixing is released and the two are moved away from the axial direction to some extent. . However, if the moving distance between the two axes in the axial direction becomes large, the meshing of the two will be separated, and the rotation cannot be transmitted.

In this reel, the pinion holder movement restricting member 43 for restricting the movement of the first pinion holder 41c toward the motor 5 side is provided, whereby the moving distance of the first pinion holder 41c in the axial direction is suppressed. Specifically, when the first pinion holder 41c moves toward the motor 5 side, the support pin 41m of the first pinion holder 41c abuts against the pinion holder movement restricting member 43 fixed to the side surface of the zoning plate 45, so that the first pinion holder 41c is moved toward the motor 5 side. The movement toward the motor 5 side of the first pinion bracket 41c is restricted. Therefore, the engagement of the first pinion holder 41c and the second sun gear 42s can be prevented from being disengaged, and the function of the speed reduction mechanism 6 is not impaired.

When the first pinion bracket 41c is in contact with the pinion carrier movement restricting member 43, the pinion bracket movement restricting structure Since the member 43 and the support pin 41m are in contact with each other, the braking force does not act on the rotation of the first planetary gear 41p by the abutment.

For example, as shown in Fig. 6, the inner peripheral wall 52a is integrally formed with the spool 52 at the inner peripheral portion of the spool 52, and the pinion bracket movement restriction protruding from the inner peripheral wall 52a toward the first pinion bracket 41c side is provided. Member 43 is also possible.

Further, the pinion holder movement restricting member may be formed integrally with the inner peripheral wall 52a.

(b) Further other of the pinion carriage movement restricting member is shown in Fig. 7, for example.

The bracket moves the restriction member. In this example, even if the first pinion holder 41c and the second sun gear 42s are detached, the first pinion holder 41c is moved to the motor 5 side, and is supported by the first planetary gear of the first pinion holder 41c. The side surface of the 41p is also in contact with the large diameter portion 43' of the first sun gear 41s', so that the movement toward the motor 5 side of the first pinion holder 41c can be restricted.

(c) In the foregoing embodiment, the first pinion bracket is restricted by abutting the pinion carrier movement restricting member 43 with the support pin 41m. For example, the first engaging portion such as the protrusion is provided in the first pinion holder, and the second engaging portion that faces the first engaging portion in the axial direction is provided inside the reel, and These engaging portions may restrict the movement of the first pinion holder in the axial direction by abutting.

The configuration of the first planetary gear mechanism 61 is the same as that shown in FIGS. 3 and 4, and detailed description thereof will be omitted. Further, the configuration other than the speed reduction mechanism includes a configuration for restricting the movement of the first pinion holder in the axial direction, and is also completely the same as the configuration shown in FIGS. 3 and 4.

In the second planetary gear mechanism 62, only the second pinion holder 62c is different from the configuration shown in Figs. 3 and 4, and the other configurations are the same. The second pinion holder 62c of the second planetary gear mechanism 62 is formed in a tubular shape and formed in a ring shape, and has a plurality of teeth 62t similar to those in the above-described embodiment at the inner peripheral end portion.

The third planetary gear mechanism 63 includes a third sun gear 63s, a plurality of third planetary gears 63p, a third small gear carrier 63c, and a ring gear Rg (common to the ring gears of the first and second planetary gear mechanisms). ). The third sun gear 63s is an output shaft 28 that is rotatably supported by the motor 5. In the motor-side end portion of the outer peripheral surface of the third sun gear 63s, a plurality of teeth 63t are formed, and the teeth 63t are meshed with the teeth 62t formed at the inner peripheral end portion of the second pinion holder 62c. Further, the second pinion bracket 62c and the third sun gear 63s are falsely fixed, and are prohibited from being independent. The ground moves in the direction of the axis. The plurality of third planetary gears 63p are meshed with the third sun gear 63s and the ring gear Rg, respectively, and are rotatably supported by the third pinion gear by the support pin 63m, similarly to the other planetary gear mechanisms 61 and 62. Bracket 63c. The third pinion holder 63c has a cylindrical shaft 63ca extending outward in the axial direction (away from the motor side) in the inner peripheral portion, and the tip end of the cylindrical shaft 63ca is coupled to the pinion gear 36.

(e) Further embodiments are shown in Fig. 9. In the example shown in Fig. 9, the basic configuration is the same as the example shown in Fig. 8. In other words, the speed reduction mechanism of the embodiment shown in FIG. 9 includes the first planetary gear mechanism 61, the second planetary gear mechanism 62, and the third planetary gear mechanism 63. The configuration of each of the planetary gear mechanisms 61 to 63 is the same as the configuration shown in Fig. 8 except for the dimension (width) in the axial direction. In this example, the engagement between the second pinion holder 61c and the second sun gear 62s is not only the engagement of the first pinion holder 61c and the second sun gear 62s, but also the engagement of the second pinion holder 62c and the third sun gear 63s. possibility.

Here, in the example shown in FIG. 9, in the outer peripheral surface of the second sun gear 62s, a portion 65 having a larger diameter than the other outer peripheral surface is provided at the end portion on the motor 5 side, whereby The diameter portion 65 restricts the movement of the second pinion holder 62c toward the motor side. In this example, even if the false fixation of the second pinion holder 62c and the third sun gear 63s is released, the second pinion holder 62c is supported by the second planet of the second pinion holder 62c even if it moves toward the motor 5 side. The side surface of the gear 62p is also in contact with the large diameter portion 65 of the second sun gear 62s, so that the movement of the second pinion holder 62c toward the motor 5 side can be restricted. Therefore, the second pinion bracket 62c and the third too The engagement of the male gear 63s is maintained without impairing the function as a speed reduction mechanism.

Further, in the embodiment shown in Fig. 9, the pinion holder movement restricting member 43 that restricts the axial movement of the first pinion holder 61c may be omitted depending on the arrangement of the respective members.
