Description

Spinning reel

technical field

The present invention relates to a support structure for a spool shaft and a rotor of a spinning reel for fishing.

Background technique

The spinning reel for fishing has on the front end a line cup for winding the fishing line to a uniform winding thickness and a rotor for guiding the fishing line, wherein the line cup slides back and forth according to the rotation of the rocker arm, and the rotor moves along the Rotate in one direction. The rotary motion of the rocker arm is converted into the sliding motion of the spool shaft through the swing mechanism inside the reel, and the spool moves back and forth accordingly. On the other hand, regarding the rotation of the rotor, the rotation of the rocker arm is converted into the rotation of the pinion gear fixed at the rear of the cylindrical rotor rotating shaft (rotating shaft cylinder), so that the rotor fixed at the rotating shaft cylinder rotates, wherein , the pinion gear is set to surround the bobbin shaft, and the rotating shaft barrel is coaxial with the bobbin shaft. In such a structure, since the bobbin shaft and the rotating shaft cylinder are arranged close to each other, when a high load is applied during the winding operation, the friction between the two will increase, and it will continue to be used for a long time in this state. , Unsatisfactory problems such as partial friction or burn marks will occur. In addition, in order to prevent this problem, the contact surface between the two is processed into a high-precision smooth surface, which brings about the problem of increased manufacturing cost.

In order to solve the above problems, in Patent Document 1, a small gap is provided between the inner peripheral surface of the rotating shaft cylinder of the rotor and the outer peripheral surface of the cup shaft by holding the front and rear portions of the rotating shaft cylinder by bearings. However, according to the structure of Patent Document 1, the bearing that supports the planetary gear portion also supports the bobbin shaft, and thus the problem of hindering the sliding movement of the bobbin shaft tends to occur under high load. Patent Document 2 discloses a method for improving this shortcoming. The schematic diagram of its structure is shown in FIG. 8 These two places support the rotating shaft cylinder 9 and the wire cup shaft 2 and distribute the load.

However, according to the structure of Patent Document 2, since the number of bearings is increased compared with the structure of Patent Document 1, the number of contact points is increased, and the structure becomes complicated due to the increase in the number of parts, which is not conducive to the weight reduction of the fishing reel or The problem of reducing manufacturing costs. Moreover, by rotating the screw portion 10 of the shaft cylinder 9 and being fixed by the rotor nut 11, it is difficult to eliminate the wobble of the screw portion 10 in the radial direction. However, if the central position of the rotating shaft cylinder 9 deviates, a good rotating effect cannot be obtained.

Detailed ways

Embodiments of the present invention will be described in detail below with reference to the drawings. However, the present invention is not limited to the embodiments described below.

Fig. 2 is a cross-sectional view showing the structure of the reel body 120 and the rotor 130 in the spinning reel 100 for fishing according to the embodiment of the present invention. In addition, FIG. 3 is an enlarged view of a dotted line portion B in FIG. 2 , and FIG. 4 is an enlarged view of a dotted line portion C in FIG. 2 . The rotation of the rocker arm 110 is converted into the sliding (reciprocating) motion of the bobbin cup shaft 106 through the swing mechanism composed of the gear 102, the slider 104, etc., so that the bobbin cup 160 fixed on the bobbin cup shaft 106 reciprocates. At the same time, the rotation of the rocker arm 110 is combined with the rotation of the face gear 114 combined with the rocker shaft 112 , the gear portion 133 of the pinion gear (hereinafter referred to as the gear portion 133 ) and the rotating shaft cylinder portion 134 of the pinion gear (hereinafter referred to as the gear portion 133 ). The form of rotation (called the rotating shaft cylindrical portion 134) is sequentially transmitted, so that the rotor 130 fixed at the rotating shaft cylindrical portion 134 rotates. The rotating shaft cylindrical portion 134 is rotatably held by the reel main body 120 via two ball bearings 136 , 138 . In addition, the rotor 130 is rotated in only one direction by the one-way bearing 137 . In addition, the pinion gear in this embodiment is used as a separate part including the gear part and the rotating shaft cylinder part, but it is not limited to this form, as long as it is a structure that can realize its function, for example, it can also be a The gear part and the rotary shaft cylinder part are separate parts, which are combined by welding or other combination means to be used as pinion gears.

It can be seen from FIG. 2 that the bobbin shaft 106 and the rotating shaft barrel 134 usually move in a direction perpendicular to each other, so by providing a gap 132 of 0.1-0.2 mm between the two, friction between the two can be avoided. In order to maintain the gap 132, the reel main body 120 movably holds the spool shaft 106 through a flanged cylindrical rear bushing 122; the rotating shaft barrel 134 passes through a flanged cylindrical front bushing 142. The bobbin shaft 106 is rotatably contacted. In addition, in order to prevent the front bushing 142 from moving from a predetermined position, a nut 140 is fixed to the rotating shaft cylinder portion 134 . The front shaft sleeve 142 and/or the rear shaft sleeve 122 are not limited to the shaft sleeves, and can also be replaced by bearings according to actual needs.

In the present invention, resin is used for the material of the rear bushing 122 and/or the front bushing 142 . The material of the resin can be hard materials such as POM (polyoxymethylene), PA (polyamide), PPS (polyphenylene sulfide), PEEK (polyetheretherketone). Thereby, the cost reduction of a bearing can be achieved. However, the materials of the rear bushing and the front bushing are not limited thereto, as long as they are wear-resistant materials, inorganic materials such as carbon and ceramics may also be used.

Moreover, in the present invention, the inside of the main body of the fishing reel contains the gear box 108 of components such as the rocker shaft 112, the face gear 114, and the swing mechanism. The details are as described in Patent Document 3. In order to accurately keep these components in The gearbox 108 is formed as an integral part at a designated location inside the gearbox 108 . Specifically, the bearings 116 and 118 support the face gear 114, and the holes of the gear box 108 where the bearings 116 and 118 fit are machined by a computer numerical control machine tool (CNC), thereby ensuring high-precision positional accuracy. In addition, the coaxial rotating shaft barrel portion 134, the bearings 136 and 138 supporting the bobbin shaft 106, and the holes of the gear case 108 for fitting the rear bushing 122 are also machined by a computer numerical control machine tool (CNC). As a result, high-precision coaxial accuracy can be guaranteed.

In addition, as mentioned above, especially the front boss portion with high friction is formed by inserting a resin cylindrical bearing into the gap instead of using the ball bearing of the conventional technology (for example, Patent Document 2). The frame of the gear box 108 incorporating the above-mentioned components and the bobbin shaft 106 held by the frame can be easily pulled out from the rotating shaft cylindrical portion 134 coupled with the rotor 130 . On the contrary, when installing the rotating shaft barrel 134 and the rotor 130 , as long as the rotating shaft barrel 134 is inserted into the bobbin shaft 106 , the front sleeve 142 is inserted into the gap and fixed with the nut 140 . Therefore, this fishing reel can be easily maintained, repaired and reassembled compared to the conventional structure using ball bearings.

In this regard, the structure of the conventional gearbox is to install the rocker shaft, end gear, swing mechanism and other components in the frame, and then use screws to assemble the side plate on the frame. This structure is not easy to realize. The rocker shaft 112 and the spool shaft 106 are assembled while maintaining the correct vertical positional relationship. When screwing, the spool shaft 106 is installed so as to be slightly inclined from the vertical position, which will cause the spool shaft 106 and the rotating shaft barrel 134 easily produces the shortcoming of friction. In the present invention, the rocker arm shaft 112 and the spool shaft 106 always maintain the correct vertical positional relationship, so even after maintenance and repair, and after the fishing reel is reassembled, the gap 132 can still be kept correctly at the specified value all the time .
