Description

  The present invention relates to a drag mechanism that employs a multi-plate clutch as a drag adjusting clutch of an electric reel for fishing.

  Especially when fishing over medium items in fishing, the pulling force of the fish may exceed the reel winding torque, which not only causes the fish to break off, such as thread breakage, cuts of the body, mouth breakage, etc. It may also cause burn-in of Therefore, conventionally, a drag mechanism in which a clutch plate capable of adjusting a frictional engagement force is incorporated in a transmission mechanism of a motor and a spool is known.

  Further, since a drag mechanism including a friction disk and a brake disk as a set is inferior in durability, a drag mechanism including a so-called multi-plate clutch including a plurality of sets of these is also disclosed in Patent Documents 1 to 3, for example. Has already been proposed by the present applicant.

  However, those disclosed in Patent Documents 1 to 3 relate to a reel that can be switched between electric and manual among fishing reels, and not to an electric reel that is intended to be wound up by a motor alone. In other words, in the switching type reel, drag adjustment is possible regardless of whether it is electric or manual, and the internal structure becomes very complicated.

  The present invention has been made in view of the above-described problems, and an object thereof is to disclose a drag mechanism for an electric fishing reel that enables drag adjustment by a multi-plate clutch with a relatively simple configuration. .

  In order to achieve the above-described object, in the present invention, a connecting disk that is slidably and coaxially supported with a main gear that transmits motor power and is detachably connected to the main gear by the sliding is provided at one end of the shaft. In the clutch housing portion, a supported drive shaft, a spool in which the drive shaft is inserted, and a space formed by a recessed portion formed on the end surface on the main gear side and the coupling disk is used as a clutch housing portion; A clutch having a lining disk interposed between a plurality of rotating disks provided so as to be able to co-rotate alternately on the outer periphery of the drive shaft and the inner periphery of the recessed portion of the spool, and horizontally moves the drive shaft together with the spool in the axial direction. The coupling disk can be engaged with and disengaged from the main gear and the frictional engagement force of the clutch can be adjusted. To constitute a drag mechanism of the electric fishing reel from the clutch operation unit.

  Further, it is preferable that the rotary disk of the clutch is provided so as to be able to rotate together with the outer periphery of the drive shaft and the inner periphery of the concave portion of the spool by key coupling that is unevenly fitted.

  Further, it is preferable that the connecting disk of the drive shaft and the main gear are connected by a pin that is biased by a spring and protrudes in the axial direction, and a pin hole into which the pin is inserted and engaged.

  Furthermore, the clutch operation unit is composed of a lever body that can be rotated by a certain amount, and a pressing body that abuts the drive shaft via a cam that can convert the rotational motion of the lever body into a horizontal sliding motion. Is preferred.

  In the present invention, since the above-described means is used, drag adjustment with high durability and high accuracy in a wide range is possible by the multi-plate clutch. In addition, the clutch structure is provided with a connecting disk for connection with the main gear at one end of the drive shaft, and a recessed portion that is closed by the connecting disk at one end of the spool so that both spaces serve as a clutch housing part. The clutch housing is realized by a relatively simple structure in which a plurality of rotating disks are arranged with a lining disk interposed therebetween. Furthermore, since all the structural members are arranged on the same axis, the structure is further simplified, and both on / off of the clutch and frictional engagement force (clutch pressure) can be collectively controlled by one clutch operation unit. it can. Furthermore, if the concave / convex fitting of the key coupling is employed as a means for providing the rotating disk so as to be able to rotate together with the drive shaft and the spool, processing and assembly are simplified and productivity is increased. In addition, the means for connecting the drive shaft and the main gear by pin engagement can be connected in a detachable manner with a simple configuration, and the pin is spring-biased, so that it is inserted into the pin hole. And the separation can be performed smoothly, and these can be performed even if it is slightly rotated. Furthermore, although the clutch operation unit of the present invention has a simple configuration, the clutch pressure can be precisely controlled by the rotation angle of the lever body and the sliding amount that increases or decreases linearly.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a sectional view showing an entire fishing reel according to an embodiment of the present invention. First, in this reel, the main shaft 1 serving as the base shaft of the spool is fixed to the reel body 2 so as to form a so-called dual-bearing reel. A main gear 3 is connected to a pinion gear 6 of a motor 5 through a reduction gear 4 on one side (the left side in the drawing) of the main shaft 1 and is rotated by motor power. A spring-biased pin 3a is provided on one end surface of the main gear 3 so as to protrude in the axial direction.

  A drive shaft 7 is rotatably supported on the main shaft 1 adjacent to the main gear 3, and the drive shaft 7 is inserted into the center hole so that the spool 8 can be rotatably supported with the main shaft 1 as a base shaft. Has been.

  The power transmission configuration of the main gear 3, the drive shaft 7, and the spool 8 will be described. First, the main gear 3 and the drive shaft 7 are provided with a pin 3 a of the main gear 3 at one end of the drive shaft 7 on the main gear 3 side. It is connected by inserting and engaging with the pin hole 7b of the connecting disk 7a and rotates together. This insertion engagement is performed by sliding the drive shaft 7 along the main shaft 1 toward the main gear 3 whose position is fixed. That is, the drive shaft 7 is rotatably supported on the main shaft 1 and slides in the axial direction. Further, since the open end of the insertion hole is engaged with the flange end of the drive shaft 7 via the bush on the opposite side of the main gear 3, the spool 8 slides the drive shaft 7 to the main gear side. Then, the spool 8 can be slid to the main gear side accordingly. The structure for sliding is described later.

  Then, by sliding the drive shaft 7, the power of the main gear 3 is transmitted to the drive shaft 7 when the above-described pin engagement is reached. It does not rotate and is in a free state. In order to rotate the spool 8, the drive shaft 7 is further slid toward the main gear 3, whereby the power of the drive shaft 7 is transmitted to the spool 8 through the clutch.

  Therefore, the structure of the clutch will be described. A concavity 8a is formed in the end surface of the spool 8 on the main gear side so as to be circularly concave toward the center in the axial direction, and the connecting disk 7a fixed to one end of the drive shaft 7 is formed. By closing the recessed portion 8a, the closed space is used as a clutch housing portion. As shown in FIG. 2, the clutch accommodated here is configured by sandwiching a lining disk 11 between a plurality of sets of rotating disks 9 and 10. Here, there are two types of rotating disks 9 and 10, one that can be rotated together with the drive shaft 7 and one that can be rotated together with the spool 8, and these two types of rotating disks 9 and 10 Alternatingly arranged, a lining disk 11 is interposed therebetween. Specifically, in this embodiment, three rotating disks 9 and 10 are used, and five lining disks 11 are used.

  Further, in order to allow the rotating disks 9 and 10 to rotate together with the drive shaft 7 and the spool 8, as illustrated in FIG. It can be built into the department. That is, on the drive shaft 7 side, a concave groove 7b extending in the axial direction is formed in the axial periphery of the shaft end located in the accommodating portion, and the corresponding rotating disk 9 is formed on the inner periphery of the insertion hole with the concave groove 7b. A convex portion 9a that is key-coupled with the concave portion 7a is formed, and the convex portion 9a is engaged with the concave and convex portions so as to match the concave groove 7b, and a plurality of rotating disks 9 are inserted into the drive shaft 7 and arranged in the axial direction. On the other hand, on the spool 8 side, a concave groove 8b is formed on the inner peripheral surface of the concave portion 8a in the axial direction, and a convex portion 10a key-coupled to the concave groove 8b is formed on the outer periphery of the rotating disk 10 corresponding thereto. And a plurality of rotating disks 10 are arranged in the housing portion in the axial direction by engaging the convex portions 10a with the concave and convex portions so as to match the concave grooves 8b. In the present embodiment, the connecting disk 7a is also pivotally supported on the drive shaft 7 by the same key coupling structure as that of the rotating disk 9.

  If the drive shaft 7 is slid to the main gear 3 side by such a clutch structure, first, the drive shaft 7 and the main gear 3 are connected by pin engagement, and the clutch is turned on. However, since the clutch pressure is zero in this state, no power is transmitted to the spool 8 and the spool 8 is in a free state. If the drive shaft 7 is further slid to the main gear 3 side from this state, the degree of adhesion (pressure contact force) between the rotary disks 9 and 10 and the lining disk 11 increases, and the power of the drive shaft 7 is spooled by the frictional engagement. 8 and the spool 8 rotates.

  If the sliding amount of the drive shaft 7 is increased, the frictional engagement force between the rotating disks 9 and 10 and the lining disk 11 is increased, so that it is of course possible to increase the torque at which slip occurs, that is, the drag force. In addition, as in the present invention, a multi-plate clutch has high durability, and precise drag adjustment is possible by forming a plurality of friction surfaces. By this precise drag adjustment, a drag force fine adjustment mechanism, which has been conventionally required, can be omitted.

  Next, returning to FIG. 1, the variable mechanism of the drag adjustment amount in this reel, that is, the clutch operating part for sliding the drive shaft 7 will be described. The drag adjustment is performed on the other end side (right side of the drawing) of the main shaft 1. A rotating lever 12 is provided, and the rotating motion of the rotating lever 12 is converted into a linear motion in the axial direction by a cam 13. That is, the cam 13 is composed of a first cam 13a and a second cam 13b that are coaxially supported on the main shaft 1, and the first cam 13a and the second cam 13b are as shown in FIG. A cam crest 13c and a cam groove 13d are formed in a certain range of the mating surfaces to be engaged with each other. Then, by rotating the first cam 13a by the rotary lever 12, the cam crests 13c and 13d are disengaged, and the cam crest 13c presses the second cam 13b, so that the second cam 13b is moved in the axial direction. Slide. The tip (pressing body) of the sliding second cam 13b presses the bearing mechanism incorporated in the insertion hole of the drive shaft 7 so that the drive shaft 7 is moved to the main gear 3 side. I have to. On the other hand, if the rotary lever 12 is reversed from the clutch-on state to the original position, the second cam 13b moves backward, and the drive shaft 7 is connected to the main gear 3 by the urging force of the main spring 14 built in the drive shaft 7. Can slide to the opposite side, weakening the drag force, and disengaging the clutch.

  In short, in the present invention, a multi-plate clutch is configured between the drive shaft 7 and the spool 8 at one end on the main gear 3 side, while the drive shaft 7 is slid together with the spool 8 toward the main gear 3 side. A multi-plate clutch drag adjusting mechanism capable of precisely controlling the drag force can be realized with a relatively simple configuration. In particular, a multi-plate clutch can be easily constructed by alternately supporting the rotating disks 9 and 10 and the lining disk by using the recessed portion 8a provided in the spool 8 as a cylinder, and further, each rotating disk 9 and 10 and the drive shaft. 7. The co-rotating structure of the spool 8 can also be easily configured by key combination. Further, since the necessary constituent members are arranged on the main shaft 1, the structure is further simplified and the assembly can be easily performed.
