Description

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

  Usually, an electric fishing reel is provided with a transmission to perform a winding operation according to the situation. As such a transmission, there is generally known an electric transmission that controls the amount of current supplied to the drive motor to increase or decrease the motor output, thereby changing the rotation speed of the spool. Yes.

Patent Document 1 discloses a high-speed reduction gear mechanism and a low-speed reduction gear mechanism between a motor output unit and a spool power transmission mechanism so that an electric hoisting operation corresponding to a change in the situation of a fishing ground can be performed. Are connected, and either one is selected according to the rotation direction of the motor to enable switching between high and low speed power transmission. That is, by switching the power transmission gear system having a different gear ratio to a high-speed or low-speed power transmission state by changing the rotation direction of the motor, the motor rotation speed transmitted to the spool, that is, the spool winding speed Can be switched between a two-stage low-speed power transmission state and a high-speed power transmission state.
JP 2001-148978 A

  In the configuration disclosed in Patent Document 1 described above, the low-speed power transmission mechanism has a low-speed gear (gear 22 shown in FIG. 3) that meshes the output from the motor with a motor gear (pinion gear) fixed to the motor shaft. ) To the transmission shaft (rotary shaft 24 shown in FIG. 3) installed coaxially with the low-speed gear, and then transmitted to the spool side via the speed reduction mechanism 15 installed on the rotational shaft 24. It is configured to On the other hand, the high-speed power transmission mechanism is installed on the same axis via a high-speed gear (gear 25 shown in FIG. 3) that meshes the output from the motor with a motor gear (pinion gear) fixed to the motor shaft. It is transmitted to a large-diameter intermediate gear (gear 35 shown in FIG. 3), and is transmitted to a small-diameter intermediate gear (gear 29 shown in FIG. 3) installed on the rotary shaft 24. 24 is increased (accelerated by the gear ratio between the large-diameter intermediate gear 35 and the small-diameter intermediate gear 29).

  In other words, in the above-described configuration, the high-speed power transmission mechanism transmits the increased rotation to the gears (gears 22 and 29) installed for low speed, so that the meshing sound at the time of high-speed driving increases. As a result, the angler is uncomfortable and the gears installed for low speed and the bearings thereof wear out. In particular, when a load is applied during high-speed driving, the meshing noise further increases, and a large load is applied to the gear installed for low speed and the support portion thereof.

  The present invention has been made on the basis of the above-mentioned problems, and can switch between low-speed driving and high-speed driving with a simple structure, and can reduce the gear meshing noise during electric driving and achieve comfortable high-speed winding. An object is to provide an electric reel for fishing that can be performed.

To achieve the above noted object, an electric fishing reel according to the present invention, a drive motor for rotating the spool of the fishing line for winding which is rotatably supported rotating the reel unit, the output of the drive motor And a transmission having a high-speed gear transmission mechanism and a low-speed gear transmission mechanism, coupled to the power transmission mechanism that transmits the rotation of the output section to the spool, and the output section of the drive motor. In the configuration in which either one of the high-speed gear transmission mechanism and the low-speed gear transmission mechanism is selected according to the rotation direction, and the high-speed rotation driving force or the low-speed rotation driving force is transmitted to the power transmission mechanism, the high-speed gear transmission The mechanism transmits the rotation of the drive motor in one direction to the power transmission mechanism without increasing the speed, and the low speed gear transmission mechanism decelerates the rotation of the drive motor in the other direction to transmit the power transmission. Characterized by transmitting to the structure.

  According to the fishing electric reel having the above-described configuration, either the high-speed gear transmission mechanism or the low-speed gear transmission mechanism is selected by switching the rotation direction of the drive motor. In this case, since the high-speed gear transmission mechanism does not perform a speed increasing action that exceeds the motor rotation speed of the drive motor, the gear meshing sound during electric drive is reduced, and comfortable high-speed winding can be performed. become.

  According to the present invention, it is possible to obtain an electric fishing reel capable of switching between low-speed driving and high-speed driving with a simple structure and capable of performing comfortable high-speed winding by reducing gear meshing noise during electric driving. .

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 3 is an enlarged view of the transmission, FIG. 3 is a schematic diagram for explaining the power transmission path in the high speed gear transmission mechanism, and FIG. 4 is a schematic diagram for explaining the power transmission path in the low speed gear transmission mechanism.

  The electric fishing reel 1 of this embodiment includes a reel body 4 to which a manual handle 2 is attached. Between the left and right frames constituting the reel body 4, the spool shaft 10 is rotatably supported via a bearing 80, and the spool 12 is disposed so as to surround the spool shaft 10.

  Further, a spool drive motor (hereinafter referred to as a motor) 14 capable of rotating in the forward and reverse directions is held between the left and right frames of the reel body 4. The rotational force of the rotational drive shaft (output unit) 14 a of the motor 14 is as follows. The power is transmitted to the spool 12 via a transmission 19 and a power transmission mechanism 15 which will be described later.

  The power transmission mechanism 15 is installed on the left frame side and the right frame side of the reel body 4, and on the left frame side, there is a gear train (drive gear 45, intermediate gear 47, spool drive gear 60 that transmits power). ) And a first reduction mechanism 16 having a planetary gear for reducing the rotational driving force of the motor 14, and a second reduction mechanism 17 having a planetary gear is arranged on the right frame side. ing. In this case, as shown in the figure, the first speed reduction mechanism 16 is installed on the left frame side and the second speed reduction mechanism 17 is installed on the right frame side. There may be.

  The spool driving gear 60 is fitted to one end of the spool shaft 10 so that the rotational driving force decelerated by the first reduction mechanism 16 and input to the driving gear 45 is spooled via the intermediate gear 47. It is transmitted to the shaft 10. Then, the rotational driving force transmitted to the spool shaft 10 is further decelerated via the second reduction mechanism 17 and transmitted to the spool 12.

  The above-described drive gear 45 is inputted with a high-speed rotation drive force or a low-speed rotation drive force by the transmission 19 described below. As shown in FIG. 3 and FIG. 4, it is rotationally driven counterclockwise when FIG. 1 is viewed from the left side. The rotation direction of the drive gear 45 is such that the spool 12 rotates in the fishing line winding direction.

  Next, the configuration of the transmission 19 described above will be described.

  As shown in FIGS. 3 and 4, the transmission 19 is installed between the rotation drive shaft (output unit) 14 a of the motor 14 and the power transmission mechanism 15. A high-speed gear transmission mechanism 19A and a low-speed gear transmission mechanism 19B that receive power transmission from the pinion gear 20 that is fixed to the rotation drive shaft 14a of the motor 14 in order to transmit the rotation to the spool at high speed or low speed. It has.

  The high-speed gear transmission mechanism 19A is fastened to the high-speed input gear 22 that meshes with the pinion gear 20, a first rotary shaft 24 that supports the high-speed input gear 22, and the first rotary shaft. A large-diameter gear (high-speed output gear) 29 is provided. A first one-way clutch 23 is interposed between the first rotary shaft 24 and the high-speed input gear 22.

  The low-speed gear transmission mechanism 19B is fixed to the low-speed input gear 25 that meshes with the pinion gear 20, the second rotary shaft 28 that supports the low-speed input gear 25, and the second rotary shaft. And a small-diameter gear (low-speed output gear) 35. A second one-way clutch 26 is interposed between the second rotary shaft 28 and the low speed input gear 25.

  The high-speed input gear 22 and the low-speed input gear 25 have the same outer diameter (the same gear ratio as the pinion gear 20) is set (of course, it may not be the same). The first one-way clutch 23 and the second one-way clutch 26 are set so that their rotational directions for transmitting force are opposite to each other.

  That is, the first one-way clutch 23 is rotated in the counterclockwise direction as shown in FIG. 3 when the high-speed input gear 22 is rotated (hereinafter, in FIG. 3 and FIG. When the high-speed input gear 22 is driven to rotate in the forward direction, the rotational force is transmitted to the first rotational shaft 24. It is not transmitted to the rotating shaft 24. On the other hand, the second one-way clutch 26, when the low speed input gear 25 is rotationally driven in the forward rotation direction as shown in FIG. When the low speed input gear 25 is driven to rotate in the reverse direction, the rotational force is not transmitted to the second rotating shaft 28.

  The first rotating shaft 24 is rotatably supported between the first frame 50 of the reel body 4 and a carrier 40 described later via bearings 21 and 43. The second rotary shaft 28 is rotatably supported between the first frame 50 and the second frame 51 of the reel body 4 via bearings 27 and 33.

  The large-diameter gear (high-speed output gear) 29 of the high-speed gear transmission mechanism 19A and the small-diameter gear (low-speed output gear) 35 of the low-speed gear transmission mechanism 19B mesh with each other, as will be described later. The rotational driving force of the low speed output gear 35 rotationally drives the first rotary shaft 24 while being decelerated via the high speed output gear 29. Note that the rotational driving force of the high-speed output gear 29 is transmitted to the second rotary shaft 28 while being accelerated through the low-speed output gear 35, but the operation of the second one-way clutch 26 described above. Thus, the second rotating shaft 28 only idles. That is, during high-speed rotation, power is transmitted without interposing the low-speed output gear 35.

  The gear ratio between the high-speed output gear 29 and the low-speed output gear 35 is set so that the ratio between the rotational speed of the spool 12 in the high-speed mode and the rotational speed of the spool 12 in the low-speed mode becomes a desired value. ing.

  Both the output of the high-speed gear transmission mechanism 19 </ b> A configured as described above and the output of the low-speed gear transmission mechanism 19 </ b> B are output from the first rotating shaft 24, and the power transmission mechanism 15 is configured as described above. The first speed reduction mechanism 16 decelerates and is transmitted to the spool 12 side through the power transmission mechanism 15 as it is.

  The first speed reduction mechanism 16 is disposed between the sun gear 30 that is rotationally fitted to the first rotating shaft 24, the second frame 51, and the sun gear 30, and the sun gear 30 and the second gear. A plurality of (three in this embodiment) planetary gears 36 that mesh with the internal teeth 31 formed on the frame 51. In this case, the planetary gear 36 is rotatably supported by the carrier 40 via the support shaft 37. The carrier 40 is rotatably supported between the second frame 51 and the third frame 52 via bearings 42 and 41. The carrier 40 is fitted with the aforementioned drive gear 45 in a non-rotating manner.

  The reel body 4 is provided with a high-speed mode switch S1 and a low-speed mode switch S2 as switching operation members for switching modes of the rotational speed of the spool 12. In this case, when the high-speed mode switch S1 is turned on, the rotational drive shaft 14a of the motor 14 is normally driven as shown in FIG. 3, and when the low-speed mode switch S2 is turned on, the rotational drive shaft 14a of the motor 14 is As shown in FIG. 4, it is reversely driven.

  Next, the operation of the fishing electric reel 1 having the above-described configuration will be described.

[High-speed mode]
First, when the high-speed mode switch S1 is turned on, as shown in FIG. 3, the rotational drive shaft 14a of the motor 14 is driven to rotate forward. When the rotation drive shaft 14a is driven to rotate in the forward direction, both the high speed input gear 22 and the low speed input gear 25 that mesh with the pinion gear 20 are reversed. At this time, the first one-way clutch 23 transmits the rotation of the high-speed input gear 22 to the first rotating shaft 24 by the above-described action, while the second one-way clutch 26 transmits the rotation of the low-speed input gear 25 to the first rotation shaft 24. 2 is not transmitted to the rotary shaft 28. Accordingly, the first rotary shaft 24 is rotationally driven in the reverse direction at a rotational speed corresponding to the rotational speed of the rotational drive shaft 14 a and the gear ratio between the pinion gear 20 and the high-speed input gear 22. In this case, the gear ratio is set between the pinion gear 20 and the high-speed input gear 22 so that the driving force is transmitted without increasing the speed.

  When the first rotary shaft 24 is driven in reverse, the high-speed output gear 29 that is locked to the first rotary shaft 24 is also reversely rotated, and the low-speed output gear 35 that meshes with the high-speed output gear 35 and the anti-rotation fit to this. The combined second rotating shaft 28 rotates forward. In this case, the rotation direction of the second rotating shaft 28 and the rotation direction of the low-speed input gear 25 are opposite to each other, but the second one-way clutch 26 is interposed between them, so the low-speed input The gear 25 and the second rotation shaft are idle (the high speed gear transmission mechanism 19A functions as a power transmission state, and the low speed gear transmission mechanism 19B does not function).

  As described above, when the first rotating shaft 24 is rotated in the reverse direction, the sun gear 30 fitted to the rotation is rotated in the reverse direction, and the planetary gear 36 meshing with the sun gear 30 is rotated in the normal direction with respect to the carrier 40. At this time, since the second frame 51 is fixed, the planetary gear 36 that meshes with the inner teeth 31 formed on the second frame 51 receives a reaction force from the inner teeth 31 side while rotating forward (spinning). Then, the carrier 40 supporting the planetary gear 36 revolves around the sun gear 30 while applying a force for reversing the carrier 40. That is, the rotation of the first rotating shaft 24 is transmitted to the carrier 40 while being decelerated, and the carrier 40 is reversely rotated integrally with the drive gear 45. That is, the rotational driving force output from the motor 14 via the high-speed gear transmission mechanism 19 </ b> A is output to the drive gear 45 while being decelerated by the first reduction mechanism 16. When the drive gear 45 rotates in the reverse direction, the spool 12 is rotated at a predetermined speed (high speed) in the direction of winding the fishing line via the power transmission mechanism 15 (the gears 47, 60, etc.) described above.

[Low speed mode]
Next, when the low-speed mode switch S2 is turned on, the rotational drive shaft 14a of the motor 14 is driven in reverse as shown in FIG. When the rotation drive shaft 14a is driven in reverse, both the low speed input gear 25 and the high speed input gear 22 meshing with the pinion gear 20 are reversed. At this time, the second one-way clutch 26 transmits the rotation of the low-speed input gear 25 to the second rotation shaft 28 by the above-described action, while the first one-way clutch 23 transmits the rotation of the high-speed input gear 22 to the second rotation shaft 28. 1 is not transmitted to the rotating shaft 24. Therefore, the second rotary shaft 28 is rotationally driven in the forward rotation direction at a rotational speed corresponding to the rotational speed of the rotational drive shaft 14 a and the gear ratio between the pinion gear 20 and the low-speed input gear 25. In this case, the gear ratio is set between the pinion gear 20 and the low-speed input gear 25 so that the driving force is transmitted without increasing the speed.

  When the second rotary shaft 28 is driven to rotate forward, the low-speed output gear 35 that is rotationally engaged with the second rotary shaft 28 also rotates forward, and rotates around the high-speed output gear 29 that meshes therewith. The first rotary shaft 24 that is fixedly fitted is reversely rotated. In this case, the rotation direction of the first rotating shaft 24 and the rotation direction of the high-speed input gear 22 are opposite to each other. However, since the first one-way clutch 23 is interposed therebetween, the high-speed input The gear 22 and the first rotation shaft are idle (the low speed gear transmission mechanism 19B functions as a power transmission state, and the high speed gear transmission mechanism 19A does not function). At this time, due to the gear ratio between the low-speed output gear 35 and the high-speed output gear 29, the rotation of the low-speed output gear 35 is output to the first rotary shaft 24 in a decelerated state. That is, when the motor 14 is driven in reverse, the first rotary shaft 24 is driven in reverse as in the case where the motor 14 is driven forward, but the low-speed output gear 35 and the high-speed output gear 29 described above. The gear ratio between and the high-speed mode is output to the power transmission mechanism 15 side including the speed reduction mechanism 16 in a decelerated state as compared with the high speed mode. Rotated at low speed compared to high speed mode.

  As described above, the electric fishing reel 1 of the present embodiment increases the rotational speed (winding speed) of the spool 12 simply by switching and controlling the rotational direction of the motor 14 by the transmission 19 described above. It is possible to switch between the mode and the low speed mode. At this time, in either case of the high speed mode / low speed mode, the first rotary shaft 24 serving as the final output shaft is within the range of the rotational speed of the motor 14 in the high speed state / low speed reduced more than that. It is driven in reverse in the state.

  In the above configuration, when the high speed gear transmission mechanism 19A is selected, the drive gear 45 is driven to rotate without the low speed output gear 35 of the low speed gear transmission mechanism 19B being interposed in the power transmission path. The speed ratio is not affected by the gear ratio of this portion, and it is possible to prevent the speed increasing speed from exceeding the motor speed. Accordingly, the meshing sound of the gear during electric drive is reduced, and a comfortable high-speed winding can be performed, and the gear and its supporting portion are prevented from being worn.

  The present invention includes a high-speed gear transmission mechanism that switches between a high-speed mode and a low-speed mode by switching between normal rotation and reverse rotation of the motor, and a transmission that includes a low-speed gear transmission mechanism. Without increasing the rotation of the motor in one direction, it transmits to the power transmission mechanism that transmits power to the spool, and the low-speed gear transmission mechanism decelerates the rotation in the other direction of the motor and transmits it to the power transmission mechanism. If configured to do so, the arrangement method of each power transmission path, the meshing relationship of each gear, and the like can be appropriately modified. In other words, the configuration as in the above-described embodiment is configured such that power can be transmitted without interposing the low speed output gear 35 of the low speed gear transmission mechanism 19B in the driving force transmission path in the high speed gear transmission mechanism 19A. If it is good.

  For example, FIGS. 5 and 6 show another embodiment of the transmission, FIG. 5 is a diagram showing a power transmission path in a high speed mode by a high speed gear transmission mechanism, and FIG. 6 is a low speed gear transmission mechanism. It is a figure which shows the power transmission path | route of the low speed mode by.

  In the above-described embodiment, the speed reduction mechanism 16 is installed at the portion where the transmission 19 is installed, and in any mode, the rotational driving force is finally transmitted by one output shaft (first rotating shaft 24). However, as shown in these drawings, the speed reduction mechanism may be eliminated and power may be transmitted from the output shaft corresponding to each mode.

  That is, the high speed gear transmission mechanism 19A shown in FIG. 5 is configured to transmit the normal rotation drive from the motor 14 to the first rotating shaft 24 via the high speed input gear 22 and the first one-way clutch 23. A large-diameter drive gear 45A constituting the power transmission mechanism 15 is fixed to the first rotating shaft 24. On the other hand, the low speed gear transmission mechanism 19B shown in FIG. 6 is configured to transmit the reverse drive from the motor 14 to the second rotating shaft 28 via the low speed input gear 25 and the second one-way clutch 26. A small-diameter drive gear 45B constituting the power transmission mechanism 15 is fixed to the second rotating shaft 28. The drive gear 45A and the drive gear 45B are meshed with each other, and in the high-speed mode, the power is not transmitted via the small-diameter drive gear 45B (the motor output is not increased), and the spool Is transmitted to the side. Further, in the low speed mode, the speed is reduced by the gear ratio between the small-diameter drive gear 45B and the large-diameter drive gear 45A and is transmitted to the spool side.

  According to such a configuration, the same operational effects as those of the above-described embodiment can be obtained, and the speed reduction mechanism 16 does not need to be arranged. Therefore, the configuration of the transmission device can be simplified and the thickness can be reduced. Is also possible. In the configuration shown in FIGS. 5 and 6, the speed reduction mechanism may be installed by configuring the right frame side of the reel body shown in FIG. 1 in two stages.
