The continuously variable induction motor has the characteristic of automatically varying the rotation speed and torque, and the characteristic of changing the rotation speed steplessly from 0 to no-load rotation speed depending on the magnitude of torque with a constant output. The gist is that an output shaft is connected via a reduction gear, a clutch device, and a brake device, and a take-up reel is attached to the output shaft.

It has the characteristic that the rotational speed can be changed steplessly from 0 to the no-load rotational speed.

Reference numeral 6 denotes a planetary reduction gear, which has a second auxiliary shaft 32 and a third auxiliary shaft 33 in front of the first auxiliary shaft 2, and an output shaft 5 in front of the third auxiliary shaft 33. The output shaft 5 is provided with bearings 2 on the walls of the gear box 34 and the brake box 35.
Similarly, a first sun gear 36, which is supported via shafts 2 and 23 so that the tip of the output shaft 5 is brought out of the brake box 35, and which functions as an input gear is placed at an intermediate position of the first auxiliary shaft 2. A second sun gear 37 is integrally provided at an intermediate position of the second auxiliary shaft 32, and a third sun gear 38 is integrally provided at an intermediate position of the third auxiliary shaft 33, and a first spider is provided at the base end of the second auxiliary shaft 32. 7, a second spider 81 is similarly provided at the base end of the third auxiliary shaft 33, and a third spider 5' is similarly provided integrally at the base end of the output shaft 5.
The first planet gear 9 meshes with the first sun gear 36 on the second spider 8, and the second planet gear 9 meshes with the second sun gear 37 on the second spider 8.
Similarly, the planetary gear 10 is attached to the third spider 5'.
A first inner shaft rotatably supports the third planetary gear 11 that meshes with the sun gear 38 through planetary shafts 12, 13, and 14, respectively, and meshes with the first planetary gear 9 and the second planetary gear 10 in a spanning state. A gear 15 is disposed to fix the first internal gear 15 non-rotatably to the gear box 34, and a second internal gear 16 meshing with the third planetary gear 11 is disposed to fix the first internal gear 15 to the gear box 34. 16 is rotatably supported on the output shaft 5 via the drum portion 1'' provided integrally with the second internal gear 16 and bearings 17, 17''.

Reference numeral 18 denotes a clutch device comprising an electromagnetic coil 21 having an iron core 20 that selectively fits into a number of engagement holes 19 provided around the outer peripheral surface of the drum portion 16'' when energized; Brake device to apply, 25 is manual winding handle 2
6 is a reel, 27 is a voltage adjustment volume for the C motor 1, and 28 is a waterproof cover.

Incidentally, the VC motor mentioned above is located at Taisei 4, Omiya City, Saitama Prefecture.
This is the trade name of a continuously variable speed induction motor manufactured and sold by Japan Patent Electric Co., Ltd., located in 591, Japan, and the VC motor has the characteristic of automatically varying torque and rotation speed according to the load. The characteristics of the control voltage, torque, and rotational speed are as shown in Figure 4. When the control voltage is changed, the torque and rotational speed are synchronized with each other, that is, the rotational speed and torque automatically vary under the same voltage. It has the characteristic that the rotation speed can vary steplessly over a wide range from 0 to no-load rotation speed depending on the magnitude of torque at a constant output.Furthermore, the starting current is small and the starting torque is large, so the start-up is smooth. This makes it possible to form a control system very quickly and easily.

That is, in order to carry out fishing in the above case, first, the VC motor 1 is rotated while the brake device 24 is applied and the clutch device 18 is disengaged.

In this way, the rotation of the central shaft 3 is decelerated for the first time by the first sun gear 36, the first planetary gear 9, and the first internal gear 15. Also, the second sun gear 37 and the second planetary gear 10
A second deceleration is performed by the first internal gear 15 and transmitted to the third sun gear 38. However, the third planetary gear 11, the second internal gear 16, the output shaft 5, and the reel 25 are connected to the third sun gear 3 depending on the disengaged state of the clutch device 18.
Regardless of the rotation or non-rotation of the third sun gear 8, the third sun gear 38 is free to rotate or is stopped by the brake device 24, so that the transmission of the rotational force of the third sun gear 38 is interrupted and the third sun gear 38 is idle. Next, in this idling state, the brake device 24 is released and the strength is adjusted, and the reel 25 starts to pay out the fishing line (not shown) by its own weight. When the length of the fishing line reached a predetermined length, the brake device 24 reduces the speed of the fishing line, and the iron core 20 is inserted into the engagement hole 19, so that the second internal gear 16 does not rotate. The rotation of the third sun gear 38 is reduced a third time by the third planetary gear 11 and the second internal gear 16, and then transmitted to the output shaft 5.
After the iron core 20 is inserted, that is, the clutch device 18 is engaged, the brake device 24 is released. If the brake device 24 is released and the fishing line starts to be fed out again or hoisting is started, operate the bowlium 27 to adjust the torque and rotational speed of the C motor 1 to adjust the feeding and hoisting speed. be moderate or zero. That is, by frequently adjusting the volume 27 and operating the brake device 24, the fishing line is wound up little by little intermittently, so that the bait attached to the fishing line is made to sway. When a fish is caught, the volume 27 is operated to set the torque and rotation speed of the VC motor 1 to the size of the target fish based on the data. In this way, the fish is caught while engaging in a so-called tug-of-war with the fish's VC motor 1. If it is found that the fish is too large, the volume 27 may be readjusted to make the force of the VC motor 1 slightly larger than the force of the fish. When removing the caught fish from the fishing line, the clutch device 18 can be removed and the reel 25 can be freely rotated. The present invention has the characteristics that the torque and rotation speed are synchronized with each other when the control voltage is changed, and the rotation speed and torque automatically change under the same voltage. An output shaft is connected to the rotating shaft of a continuously variable induction motor, which has the characteristic of changing steplessly up to the load rotation speed, via a planetary reduction gear, clutch device, and brake device, and a take-up reel is attached to this output shaft. As a result, it is of course very effective in enabling the above-mentioned fishing method, but in particular, in the present invention, the planetary reduction device, clutch device, and brake device are connected to the electric reel of the above-mentioned motor. The electric reel of the present invention has a large contribution to making it possible to use the electric reel, and is not only preferable because it has a large reduction ratio and amplification ratio and is advantageous in making the whole smaller. The winding force and speed of winding can be adjusted in an excellent manner with quick response, smoothness, and reliability, and is effective for fishing for large fish such as hairtail fish.
