Description

  The present invention relates to an electric fishing reel provided with a spool drive motor that winds and drives a spool that is rotatably supported by a reel body.

When fishing for deep fish such as boat fishing, electric reels for fishing are widely used.
2. Description of the Related Art As is well known in the art, an electric fishing reel rotates a spool by driving a spool drive motor to wind up a fishing line. As disclosed in Patent Documents 1 to 3, this type of fishing reel is used. 2. Description of the Related Art For electric reels, a structure is widely adopted in which the driving force of a spool drive motor mounted in a spool body or a reel body in front of the spool is decelerated by a planetary gear power transmission mechanism (planetary speed reduction mechanism) and transmitted to the spool.

In order to enhance the practicality, the fishing electric reel has a manual winding drive mechanism connected to the planetary gear power transmission mechanism so that it can be wound by the handle in addition to the winding drive by the spool drive motor. A combination type electric reel is generally popular.
In addition, a drag mechanism is provided in the power transmission path on the side of the manual take-up drive mechanism so that the fish can be exchanged for sudden pulling without any hindrance (break of mouth or thread breakage). When the sword tries to rotate in the direction of feeding the fishing line, the force is dragged from the planetary gear support (planetary carrier) of the planetary gear power transmission mechanism connected to the motor shaft through the motor shaft reversely locked by the one-way clutch from the spool. It is transmitted to the mechanism, and a braking force is applied to the spool by the reverse rotation prevention of the handle shaft.

However, when the drag mechanism functions in this way and braking force is applied to the spool, not only the drag mechanism but also the pulling force of the fishing line is output from the spool via the motor shaft to the planetary gear power transmission mechanism, A large load is also applied to the tooth surfaces of the gears and the support portions constituting the planetary gear power transmission mechanism.
For this reason, there is a possibility that breakage, deformation, wear, etc. may occur in the gears and support portions of the planetary gear power transmission mechanism after long-term use.

Further, if the planetary gear power transmission mechanism is provided with sufficient strength, the planetary gear power transmission mechanism is increased in size or expensive materials are used, resulting in an increase in manufacturing cost.
The present invention has been devised in view of such circumstances, and when the drag mechanism functions as the fishing line is pulled out, there is no risk that a large load is applied to the gears, the support portion, or the like constituting the planetary gear power transmission mechanism. An object is to provide an electric reel for fishing.

  In order to achieve such an object, the invention according to claim 1 includes a spool drive motor that winds and drives a spool that is rotatably supported by a reel body, and a planetary gear that transmits the driving force of the spool drive motor to the spool. A fishing electric motor comprising: a power transmission mechanism; and a drag mechanism that applies a braking force to the spool when the spool rotates as the fishing line is pulled out. The drag mechanism is connected to a planetary gear support that constitutes the planetary gear power transmission mechanism. In the reel, a one-way clutch is provided between the spool and the planetary gear support, and the spool and the planetary gear support can be integrally rotated via the one-way clutch when the spool is rotated when the fishing line is pulled out. It is characterized by that.

  According to the first aspect of the invention, when the drag mechanism functions and a braking force is applied to the spool, the spool pulling force is output from the spool to the planetary gear power transmission mechanism via the motor shaft instead of the conventional structure. Unlike the prior art, a one-way clutch is provided between the planetary gear support and the planetary gear support so that the spool and the planetary gear support can be rotated together via the one-way clutch when the spool rotates as the fishing line is pulled out. As a result, no load is applied to the tooth surfaces and supporting parts of the gears constituting the planetary gear power transmission mechanism. As a result, sufficient strength and durability can be obtained without reinforcing the gears and supporting parts. There is an advantage that downsizing can be achieved.

A plate-like holding portion 65 that is held through is fixed. The inside of the housing portion 27 is held by the holding portion 65 with a spool motor housing portion 67 that opens to the end surface 23 side of the spool 13 and a speed reduction mechanism mounting portion (hereinafter referred to as “mounting portion”) that opens to the end surface 25 side of the spool 13. 69 is defined, and the right motor shaft 71 of the spool motor 13 projects into the mounting portion 69, and three planetary gear mechanisms 73, 75, 77 are provided between the right motor shaft 71 and the spool 13. A planetary gear power transmission mechanism (planetary speed reduction mechanism) 79 is housed and mounted.

As shown in FIG. 1, a rotary drive shaft 81 that transmits the winding power from the manual winding drive mechanism 19 to the planetary gear power transmission mechanism 79 is provided between the right motor shaft 71 and the right motor shaft 71 and the side plate 11. The rotary drive shaft 81 is rotatably supported by the bracket 35 and the side plate 11 via bearings 83 and 85.
As described above, the planetary gear power transmission mechanism 79 is composed of the three planetary gear mechanisms 73, 75, and 77. When the spool motor 41 is driven, the driving force is reduced by the first planetary gear mechanism 73, and The second and third planetary gear mechanisms 75 and 77 decelerate the driving force and transmit it to the spool 13. As shown in FIG. 2, the first planetary gear mechanism 73 has a noncircular outer periphery (D-shaped cross section). A first sun gear 87 that rotates and fits together with the right motor shaft 71 formed in a shape), a plurality of planetary gears 89 that mesh with the sun gear 87, and each planetary gear 89. It is comprised with the internal gear 91 formed in the inner periphery of the mounting part 69 (spool 13) so that it may mesh | engage always.

  The second planetary gear mechanism 75 includes a second sun gear 95 that is rotatably supported by the right motor shaft 71 via a metal bearing 93, and a plurality of planetary gears 97 that mesh with the sun gear 95. The metal bearing 93 is detachably mounted in a recess 99 formed in the bearing portion of the sun gear 95 with respect to the right motor shaft 71. Each planetary gear 97 meshes with the internal gear 91.

  Similarly, the third planetary gear mechanism 77 includes a third sun gear 103 rotatably supported at the end of the right motor shaft 71 via a metal bearing 101 and a plurality of planetary gears meshed with the sun gear 103. The metal bearing 101 is detachably mounted in a recess 107 formed in a bearing portion of the sun gear 103 with respect to the right motor shaft 71. Each planetary gear 105 is structured to mesh with the internal gear 91.

The planetary gear 89 is supported by a first planetary gear support (hereinafter referred to as “planet carrier”) 109, and the planetary carrier 109 is connected to the sun gear 95 described above so as to be integrally rotatable.
The planetary gear 97 is supported by a second planetary carrier 111, and the planetary carrier 111 is connected to the sun gear 103 described above so as to be integrally rotatable.

Further, the planetary gear 105 is supported by a third planet carrier 113, and the planet carrier 113 is connected to the rotary drive shaft 81 via a locking pin 115 as shown in FIG.
As shown in FIGS. 1 to 3, in the present embodiment, a one-way clutch 117 is provided between the spool 13 and the planet carrier 113, and the spool 13 and the planet carrier 113 are rotated during the spool rotation accompanying the withdrawal of the fishing line. Can be integrally rotated via the one-way clutch 117.

  As shown in FIG. 3, the one-way clutch 117 includes a ratchet 121 that is rotationally fitted to the outer periphery of the boss portion 119 of the planetary carrier 113 formed in a square cross section, and a locking member 123 that is always in sliding contact with the ratchet 121. The locking member 123 includes a stopper (stopper piece) 127 that is pivotally attached to the end surface 25 of the spool 13 with a pin 125, and a plate spring 129 having a substantially U-shaped cross section that is attached to the distal end side of the stopper 127. In addition, both end portions 131 of the leaf spring 129 are always in frictional sliding contact with the both sides of the ratchet 121 across the outer periphery thereof.

  When the rotary drive shaft 81 rotates in the direction of arrow A along with the winding operation by the handle 21 described later, and the ratchet 121 rotates in the same direction together with the planet carrier 113 connected to the locking pin 115, the ratchet The spool 13 rotates integrally with the ratchet 121 in the fishing line winding direction (arrow A direction) by the one-way locking action of the locking member 123 that is in sliding contact with both sides of the 121 (the frictional action of the leaf spring 129). It has become.

  On the other hand, as described above, the driving force of the spool motor 41 is sequentially decelerated by the planetary gear mechanisms 73, 75, and 77, but the planet carrier 113 will rotate in the direction of arrow B when the spool motor 41 is driven to wind. However, rotation in the direction of arrow B is restricted by a well-known anti-reverse device 133, which will be described later. It rotates in the winding direction (arrow A direction).

  As shown in FIG. 1, on the rotation drive shaft 81, while giving a braking force to the spool 13 that rotates when the fishing line is fed, a braking action that allows the spool 13 to rotate in the fishing line feeding direction is given. A known drag mechanism 135 that switches the spool 13 between a spool free state and a fishing line winding state using this braking action is mounted, and the drag force of the drag mechanism 135 is applied to the side plate 11 on the rotary drive shaft 81. A drag lever 137 for adjustment is attached. Then, the pinion 141 is fitted to the pressing body 139 constituting the drag mechanism 135 so as to be integrally rotatable, and the drive gear 143 of the manual winding drive mechanism 19 is engaged with the pinion 141.

  As is well known in the art, the manual take-up drive mechanism 19 includes a handle 21, a handle shaft 145 to which the handle 21 is attached, and a drive gear 143 that is fixed to the handle 21 as shown in FIG. An anti-reverse device 133 is provided on the insertion tip side of the handle shaft 145 to prevent the handle shaft 145 from rotating in conjunction with the spool 13 when the spool 13 is driven by the spool motor 41. ing.

  The reverse rotation preventing device 133 includes a ratchet 147 screwed to the drive gear 143 and fixed to the handle shaft 145, and a locking claw 149 that is always locked to the ratchet 147 with a constant urging force. When the spool motor 41 is wound up by the spool motor 41, the driving force is transmitted from the planetary carrier 113 to the drive gear 143 via the rotation drive shaft 81, the drag mechanism 135, and the pinion 141. A locking claw 149 meshes with the ratchet 147 attached to the gear 143 in the locking direction so that the rotation of the ratchet 147, that is, the rotation of the handle shaft 145 is prevented.

As a result, as described above, the driving force of the spool motor 41 is fixed to the planet carrier 113 by the planetary reaction force, the sun gear 103 input, and the internal gear 91 output to rotate the spool 13 in the fishing line winding direction (arrow A direction). To do.
On the other hand, when the spool 13 is rotated in the fishing line winding direction by the operation of the handle 21, the locking claw 149 is configured to allow the ratchet 143 to rotate in the rotation direction. The handle shaft 145 can be rotated in conjunction with the rotation operation of the rotation shaft. As a result, as described above, the rotation drive shaft 81 rotates in the direction of the arrow A in accordance with the winding operation by the handle 21, and the When the ratchet 121 rotates in the same direction together with the planet carrier 113 connected via the stop pin 115, the spool 13 is integrated with the ratchet 121 by the locking action of the locking member 123, and the fishing line winding direction (arrow) Rotate in direction A).

  With the configuration of the one-way clutch 117 described above, when the spool 13 rotates in the direction of feeding the fishing line (in the direction of arrow C in FIG. 3) due to a sudden withdrawal of the fishing line during actual fishing, the engagement of the locking member 123 attached to the spool 13 is achieved. Since the ratchet 121 rotates in the same direction (in the direction of arrow B in FIG. 3) by the stopping action, the planet carrier 113 to which the ratchet 121 is attached directly rotates the rotation drive shaft 81 and the force is transmitted to the drag mechanism 135. As a result, by the reverse rotation prevention of the handle shaft 145 by the reverse rotation prevention device 133, a braking force is applied to the spool 13 that rotates by feeding the fishing line through the rotary drive shaft 81 that is frictionally coupled by the drag mechanism 135. The rotation in the fishing line feeding direction is allowed.

In addition, in FIG. 1, reference numeral 151 denotes a power supply cord connected to the connector 155 of the electric reel 153. Although not shown, the reel body 1 is provided with a control box equipped with an ON / OFF switch of the spool motor 41, and the spool motor 41 is driven / stopped by the operation of the ON / OFF switch. Yes.
Since the present embodiment is configured as described above, the spool motor 41 can be driven by connecting the electric reel 153 to an external power source via the power supply cord 151.

  When the drag lever 137 is rotated in the front-rear direction, a predetermined drag force is generated on the spool 13 by the drag mechanism 135. In this state, if the spool motor 41 is driven or the handle 21 is wound up, these drives are driven. The force is transmitted to the spool 13 by the planetary gear power transmission mechanism 79 or the manual winding drive mechanism 19 to rotate the spool 13 and wind up the fishing line. When the spool motor 41 performs the winding operation, the driving force of the spool motor 41 is The planetary gear mechanisms 73, 75, and 77 are sequentially decelerated. As shown in FIG. 3, the planet carrier 113 and the ratchet 121 try to rotate in the direction of arrow B. However, since the rotation of the handle shaft 145 is prevented by the reverse rotation prevention device 133, the drive gear 143 is attached to the handle shaft 145. The rotation of the pinion 141 connected via the pin is restricted.

  As a result, the rotation drive shaft 81 and the planet carrier 113 do not rotate, and the sun gear 103 rotates clockwise via the metal bearing 101, so that the planet gear 105 supported by the planet carrier 113 Rotates counterclockwise at a certain position without revolving around. In this state, the counterclockwise rotational movement of the planetary gear 105 is decelerated and transmitted to the internal gear 91, so that the spool 13 is rotated in the fishing line winding direction and the fishing line is wound up. Sometimes, the handle 21 does not rotate in conjunction with the reverse rotation preventing device 133.

  On the other hand, along with the winding operation by the handle 21, the rotation drive shaft 81 rotates in the direction of arrow A as shown in FIG. 3, and the ratchet 121 moves in the same direction together with the planet carrier 113 connected thereto by the locking pin 115. When rotated, the spool 13 rotates integrally with the ratchet 121 in the fishing line winding direction (arrow A direction) by the locking action of the locking member 123 slidably in contact with both side surfaces of the ratchet 121 (the frictional action of the leaf spring 129). To do.

When the spool 13 is rotated in the fishing line winding direction by operating the handle 21 in this manner, the locking claw 149 allows the ratchet 143 to rotate in the rotating direction. The handle shaft 145 can be rotated.
Further, when the fish hits and the fishing line is pulled by a sudden pull and the spool 13 rotates in the direction of feeding the fishing line (the direction of arrow C in FIG. 3), the locking member 123 attached to the spool 13 as described above. Since the ratchet 121 rotates in the same direction (in the direction of arrow B in FIG. 3) by the locking action, the planet carrier 113 to which the ratchet 121 is attached directly rotates the rotation drive shaft 81 and the force is transmitted to the drag mechanism 135. However, the reverse rotation prevention of the handle shaft 145 by the reverse rotation prevention device 133 applies a braking force to the spool 13 that rotates by feeding the fishing line through the rotary drive shaft 81 that is frictionally coupled by the drag mechanism 135, while the spool 13 The rotation in the fishing line feeding direction is allowed.

  As described above, in the present embodiment, when the drag mechanism functions and a braking force is applied to the spool, the spool 13 and the spool 13 are replaced with the conventional structure in which the fishing line drawing force is output from the spool to the planetary gear power transmission mechanism via the motor shaft. A one-way clutch 117 is provided between the planetary carrier 113 and the spool 13 and the planetary carrier 113 can be rotated together via the one-way clutch 117 when the spool 13 is rotated as the fishing line is drawn. Unlike the planetary gear power transmission mechanism 79 (planetary gear mechanisms 73, 75, 77), no load is applied to the tooth surfaces, support portions, etc. of the sun gears 87, 95, 103 and the planetary gears 89, 97, 105, etc. As a result, sufficient strength and durability can be obtained without reinforcing these gears and supporting parts, and the entire reel can be downsized. To.

  In the above embodiment, the one-way clutch 117 is composed of the ratchet 121 and the locking member 123. However, instead of the one-way clutch 117, a known rolling one-way clutch or the like may be used. Of course.

It is principal part sectional drawing of the electric reel which concerns on one Embodiment of Claim 1. It is an expanded sectional view of a planetary gear power transmission mechanism. It is the III-III sectional view taken on the line of FIG.
