Description

[Detailed explanation of the invention] Special public interest as a drag device for electric fishing reels.
555, Utility Model Publication No. 52-34299, etc. are known, but in all of these systems, the spool is rotatably supported on a fixed spool shaft, and a radial ball bearing is inserted into the fixed spool shaft. Since the spool's brake plate is attached to the outer ring, the radial bearing receives loads both in the axial direction and in the direction perpendicular to the axis, which causes extremely high wear and maintains the spool's smooth rotation during long-term use. There is a defect that it is not possible to perform the braking operation smoothly and reliably.

The present invention is an attempt to improve such defects in conventional electric reels, and the spool is fitted via a radial ball bearing to the spool rotating shaft, which is rotatably supported between the reel side plates using a radial ball bearing. At the same time, on one side of the spool rotating shaft, a braking plate is attached to the reel side plate supported by a thrust ball bearing, connected to the spool side plate by a lining washer, and rotated in conjunction with an electric motor so as to be movable only in the axial direction. In addition, a cam sliding tube fitted to the reel side plate so as to be movable only in the axial direction is brought into contact with the thrust ball bearing supporting the other side of the spool, and a cam sliding tube is provided on the outer end cam surface of the cam sliding tube on the reel side plate. The gist of this is that a cam operating cylinder rotated by a drag lever is engaged, and the outer end surface of the cam operating cylinder is brought into contact with the inner bottom of a drag fine adjustment screw cylinder that can move forward and backward.

An embodiment of the present invention will be described with reference to the drawings. A spool rotating shaft 4 is rotatably supported between the knoll side plates 1 and 2 via radial ball bearings 3.3, and a spool 6 is connected via radial ball bearings 5, is rotatably fitted, and a lining washer 7 is provided on one side of the spool rotating shaft 4 on the side of the reel side plate 1 with a lining washer 7 facing the spool side plate 6'. A brake plate 9 with a spring 8 interposed therebetween is freely engaged in the axial direction, and a thrust ball bearing 10 fitted into the engagement portion of the brake plate 9 is fitted onto the reel side plate 1 and is attached to the radial ball. It is supported in contact with the front surface of a metal 11 in which a bearing 3 is fitted.

Further, a pinion 14 is provided on the shaft 13 of the electric motor 12 provided between the reel side plates 1 and 2 at the rear of the spool 6. Further, a small gear 18 at the tip of the intermediate shaft 15 meshes with an annular drive gear 19 fixed to the outer peripheral edge of the brake plate 9.

On the other hand, a thrust ball bearing 21 is fitted to the spool 6 on the outside of the radial ball bearing 5 on the side of the reel side plate 2 via a collar 20, and a square collar 22 protruding from the outer surface of the thrust ball bearing 21 is attached to the spool 6 on the outside of the radial ball bearing 5 on the side of the reel side plate 2. a cam sliding tube 23 that is engaged with the side plate 2 and is movable only in the axial direction, and that has the radial ball bearing 3 engaged therein;
The outer end cylinder portion of the cam sliding cylinder 23 is fitted into a metal cylinder 24 that is integrally fixed to the reel side plate 2.

Thus, a cam operating cylinder 26 having a square retaining part 25 on the outer periphery comes into contact with the cam surface 23' of the rear end surface of the cam sliding cylinder 23, and the square retaining part 25 is rotated by the metal cylinder 24. The freely fitted rotary tube 27 engages and rotates the driver lever 28 fixed to the rotary tube 27, thereby rotating the cam operating tube 26 and moving the cam sliding tube 23 forward and backward in the axial direction. Further, a drag fine adjustment screw cylinder 29 whose inner bottom surface is brought into contact with the outer end surface of the cam operating cylinder 26 is screwed into the outer end of the rotating cylinder 27.

In addition, a ball 31 energized by a spring 30 is provided on the driver's flapper 28 so as to be able to appear and retract freely, and the ball 31 has a recess 32, 32, and
... to regulate the position of the vehicle lever 28.

In the figure, 33 is a spring that urges the drag adjustment screw tube 29 outward, 34 is a click gear provided on the spool, and 3
5 is a level wind moving gear fixed to the outside of the click gear 34, 36 is an intermediate shaft for level wind provided on the side plate 2, 37.38 is a transmission gear provided on the intermediate shaft 36, 39 is a level wind, 40 is a level wind worm shaft, and 41 is a gear that meshes with the intermediate gear 38 fixed to the worm shaft 40.

Since the embodiment of the present invention is constructed as described above, when the electric motor 12 is not overloaded, the electric motor 1
2 rotation is shaft 13, pinion 14, gear 17, intermediate shaft 1
5. The spool 6 is rotated via the small gear 18, the drive gear 19, the brake plate 9, and the lining washer 7.
When the vehicle lever 28 is rotated in this state, the cam operating cylinder 26 rotates and presses the cam sliding cylinder 23 in the axial direction, and the pressing force is sequentially applied to the thrust ball bearing 21. It is transmitted to the spool 6 via the collar 20 and the radial ball bearing 5, so by adjusting the rotation angle, the degree of pressure contact between the spool side plate 6' and the lining washer 7 of the brake plate 9 can be arbitrarily adjusted, resulting in drag braking. will be held.

Furthermore, when the drag fine adjustment screw tube 29 is rotated, the inner bottom slightly presses the cam actuating tube 26 as it advances and retreats, and the pressing force is transmitted to the spool 6 in the same order as described above, allowing fine adjustment of drag braking. .

As mentioned above, when fine-tuning the drag braking or drag braking of an electric reel, the present invention allows the spool shaft to rotate together with the braking plate without being fixed, and the axial load on the braking plate is reduced by the thrust ball. Since the load in the direction perpendicular to the bearing axis is received separately by each radial ball bearing, it is possible to prevent the conventional radial ball bearings from wearing out due to the constantly acting braking friction pressure force. However, it has excellent features and practicality that allow drag braking to be performed smoothly and reliably even during long-term use.
