Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotation of a handle, whereby a shaft coupled to the handle and rotatably supported by a main body and a rotor fixed to the shaft rotate at a fixed axial position. At the same time, the present invention relates to a spinning reel in which a spool reciprocates in the axial direction and a thread is wound around the spool via the rotor.

[0002]

2. Description of the Related Art As a conventional spinning reel, a ratchet-type reverse rotation preventing mechanism and a drag mechanism, and a one-side clutch are further provided. When the thread is stretched, the reverse-direction preventing mechanism and the one-side clutch are operated to restrain the reverse rotation of the rotor and load the load. To prevent the yarn from being unwound due to tension, the reverse rotation prevention mechanism is turned off when the yarn is wound or unwound, the rotor is allowed to rotate freely, and torque is transmitted between the load side and the handle to wind the yarn. It is possible to take out the yarn by the take-up or rotation resistance on the load side, and further by the drag mechanism,
It is known that the yarn is fed with a constant resistance torque when an excessive load is applied during winding.

However, such a spinning reel requires three separate types of mechanisms such as the on / off mechanism, the drag mechanism and the one-side clutch as described above, so that the structure is complicated and the manufacturing / assembling cost is high. It was a thing.
Further, since the conventional drag mechanism uses the sliding friction of the friction member, there is a problem that the drag torque varies depending on the environment and use conditions such as infiltration and adhesion of water and oil. Furthermore, since a cam clutch is conventionally used as the one-side clutch, the service life such as roll-on due to wear or excessive torque is short.
Further, the ratchet type on / off mechanism has a problem that a large impact force is applied to the stopper portion and a play occurs in the operation.

[0004]

SUMMARY OF THE INVENTION The present invention solves the above problems in the prior art and has a simple structure in which parts are integrated, and there is no fluctuation in drag torque or play in the rotation of the rotor.
Another object is to provide a spinning reel having a long life.

[0005]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention according to claim 1 relates to a shaft which is coupled to a handle and is rotatably supported by a main body by rotating the handle, In a spinning reel in which a rotor fixed to the shaft rotates at a fixed position in the axial direction and a spool reciprocates in the axial direction to wind a thread around the spool via the rotor, The central axis so as to form a raceway between the inner raceway surface and an inner raceway which is provided with an inner raceway surface that forms a single-leaf rotation hyperboloid and is coupled to the shaft so that torque is transmitted at a constant axial position. An outer ring that has an outer ring raceway surface that forms a single leaf rotation hyperboloid around the outer ring whose rotation is restrained from the main body so as to be freely movable in the axial direction, and a rolling surface that has a cylindrical shape, and the center line of the raceway is the center. A plurality of rollers arranged in the circumferential direction of the raceway inclined at a constant angle from a cross section including, and the surfaces linearly contacting the inner raceway surface and the outer raceway surface, and the outer race in the central axis direction. In addition to the above, the invention according to claim 2 further comprises: biasing means for biasing in a direction of narrowing the space between the tracks, and position setting means for setting the axial position of the outer ring. The position setting means includes a lever having a fulcrum, and an end of which the distance from the fulcrum is shorter presses the outer ring and an end of which is longer is positioned.

[0006]

According to the invention of claim 1, since the position setting means for setting the axial position of the outer ring is provided, and the inner ring, the outer ring and the biasing means are configured as described above, the position setting means is used. Various actions occur depending on the person.

First, when the position setting means is not operated and the axial position of the outer ring is not constrained, the action as a one-way clutch occurs. That is, the outer ring is restrained from rotating by the main body portion, but when the inner ring coupled to the handle via the shaft is rotated to the free rotation side by the rotation of the handle,
Since the inner ring freely rotates without locking with the outer ring, turning the handle causes the rotor, which is also coupled to the shaft, to rotate and wind the yarn on the spool. On the other hand, when the yarn is pulled with the handle released after long-distance throwing or winding pulling, the rotor receives rotational torque in the direction opposite to the winding direction due to the tension of the yarn that transmits the load. Since the inner ring rotates in the reverse rotation direction via the shaft, the inner ring and the outer ring are locked and the rotation of the inner ring is restricted. Therefore, the rotor does not rotate and the yarn feeding is stopped. In this case, the rotation of the inner ring in the reverse direction causes the outer ring to move in the direction of narrowing the space between the raceways in the axial direction.
Since the position setting means does not restrain the movement, even if a large torque is applied from the load side, the clutch is reliably engaged without the relative rotation between the inner and outer wheels. Since the one-side clutch portion has the above-described structure, the inner and outer races are instantly engaged with each other by the action of the urging means when rotating in the reverse direction, so that no extra yarn is paid out.

Next, when the position setting means is set to stop the movement of the outer ring at a predetermined position, an action as a drag mechanism occurs. That is, even if set in this way, the same effect as above is obtained on the free rotation side, but on the reverse rotation side,
Since the outer ring does not move in the axial direction beyond the specified position, no torque greater than the specified torque corresponding to that position is generated between the inner and outer rings, and when the load torque exceeds that torque, the inner and outer rings rotate However, the torque equal to or higher than the predetermined torque is released. Therefore, if the predetermined position is determined so that the predetermined torque becomes the desired drag torque, the one clutch portion can be used as a drag mechanism.

Further, when the outer ring is set to a position where the raceway distance between the inner and outer rings is larger than the diameter of the roller by the position setting means, the roller is not locked between the inner and outer rings and the inner and outer rings are either forward or reverse. The relative rotation is also possible in the direction of. As a result, even when the reverse rotation lock side, in which the thread is stretched from the load side, is rotated, the inner ring, the shaft, and the rotor can be freely rotated to deliver the thread.

In the above operation, since the rollers are inclinedly arranged between the inner and outer races, the rotational resistance torque generated between the rollers and the inner and outer races is the twist angle between the inner and outer races, and hence the movement of the outer race with respect to the inner race. The value corresponds to the quantity. Therefore, the rotational resistance torque can be accurately set by setting the axial position of the outer ring by the position setting means.
Further, this torque does not change due to the environment or the use condition because the friction member is not used. Further, the twisting movement of the outer ring due to the twisting is continuous, and the torque is absorbed according to the twisting angle of the inner ring with respect to the outer ring, so that, for example, the position setting means can be set to the unlocked position between the inner and outer rings to allow free movement. In order to smoothly perform the operation of drawing out the yarn, then setting the position setting means to the drag position or the inoperative position, and stopping the yarn drawing while absorbing the torque, without any impact force. Become.

According to the invention of claim 2, in addition to the above,
The outer ring position setting means uses a lever to push the outer ring at the end that is shorter than the fulcrum so that the longer end is set, so that the axial movement of the outer ring is expanded when setting the position. The position setting accuracy is improved.

[0012]

[Example] Fig. 1 shows the structure of the main operation part of the spinning reel of the example. The spinning reel includes a body 1 which is a main body fixed to a rod, a pinion shaft 2,
It has a rotor 3, a spool 4, an inner ring 5, rollers 6, an outer ring 7, a disc spring 8 as a biasing means, and an outer ring biasing device 30 as a position setting means.

The pinion shaft 2 is rotatably supported from the body 1 via a bearing 9 at a fixed axial position, and has a pinion 10 on the left end side in the drawing. On the other hand, body 1
A handle 11 is attached to the handle 11, and a drive gear (not shown) is attached to the handle 11 at a position indicated by a pitch circle 12 so as to mesh with the pinion 10. A rotor 3 is attached to the tip of the pinion shaft 2. The rotor 3 has a veil 13
The line roller 14 is attached so as to be swingable between a guide position for hooking and guiding the line thread 16 and a release position where the line thread 16 freely comes out.

The spool 4 is fixed to a main shaft 15 inserted in the pinion shaft 2. Then, the main shaft 15 is fitted with an eccentric protrusion (not shown) into an elongated hole attached to the shaft, so that the handle 11
Reciprocates in the axial direction in conjunction with the rotation of. Spool 4
Has a thread winding portion, and when the bail 13 is in the guide position as described above, the end of the thread 16 wound around the thread winding portion is wound around the line roller 14 and then the rod not shown. It goes out through a guide.

The inner ring 5 is provided with an inner ring raceway surface 5a forming a single-leaf rotating hyperboloid around the central axis 17, and is fixed to the pinion shaft 2 so that torque is transmitted at a constant axial position. Although the inner ring 5 and the pinion shaft 2 are separate bodies in this embodiment, it goes without saying that they may be integrally manufactured. The outer ring 7 is provided with an outer ring raceway surface 7a forming a single-leaf rotating hyperboloid around the same central axis 17 so as to form a raceway with the inner ring raceway surface 5a, and between the body 1 and the tip of the outer ring flange portion 7b. Rotation is movably restricted in the axial direction by an interlocking detent pin 18.

The roller 6 has a cylindrical rolling surface,
In the raceway formed between the inner and outer races, a plurality of center lines are arranged in the circumferential direction of the raceway with a center line inclined at a constant angle, for example, about 15 ° from the cross section including the central axis 17, and the surfaces thereof are the inner and outer raceway surfaces 5a and 7a. Linearly contact with. The rollers 6 are held in their relative positions by the retainer 19 so that they can rotate smoothly.

The disc spring 8 includes a bearing 20 and a spring receiving plate 21.
Via a interposed between the body 1 and the outer ring 7, the track interval in a direction of the central axis 17 of the outer ring 7, i.e. the inner ring raceway
The surface 5a and the outer ring raceway surface 7a are urged in a direction to reduce the distance between them. That is, the disc spring 8 is
The bearing 20 is pushed through the spring receiving plate 21, and this urging force is applied.
Of the bearing disc 22, which is interposed between the body 1 and
Position the ring 23 and the ring 23 that position it
The pinion shaft 2 and the axial position
Is transmitted to the bearing 9 that is supported by
The outer ring 7 is centered by being received by the existing body 1.
In the direction of movement that narrows the track spacing in the axial direction, that is,
In the direction from right to left. The biasing force of the disc spring 8 is such that when the inner and outer races relatively rotate in the clutch direction,
The preload is such that the roller 6 is reliably locked between the inner and outer rings and the inner and outer rings are clutched.

In the present embodiment, the outer ring urging device 30 has an outer ring pressing plate 31 which is in pressure contact with the outer ring 7, a fulcrum plate 32, a lever 33 whose one end side is in contact with the fulcrum plate 32 and the outer ring pressing plate 31, and one end side. It has a drag / stopper shaft 34 that contacts the other end of the lever 33, and a setting knob 35 that has a threaded portion and that is screwed into the threaded portion of the body 1 and that has the other end side of the drag / stopper shaft 34 fixed. And the setting knob 35
Is a lever 33 according to the usage condition of the spinning reel.
Is sufficiently separated from the push plate 31 and the outer ring urging device 30 does not operate, and the lever 33 can be operated only by the urging force of the disc spring 8.
Does not contact the push plate 31, but when the outer ring 7 moves during rotation in the clutch direction, the second set position that stops the movement at a predetermined position and the drag / stopper shaft 34 compress the disc spring 8 to the right in the figure. It is set by any suitable means to any one of the three positions including the third set position where the clutch is not operated. Of these, the second position may be freely set by rotating the setting knob 35. However, for example, the second position may be selected from three types of positions of strong, medium, and weak. Good. The fulcrum plate 3
2 is axially positioned from the inner ring 5 via a thrust bearing 36. In this way, the outer ring biasing device 3
It is easy to maintain the dimensional accuracy of 0. However, it is also possible to directly provide the fulcrum on the body 1 without providing the fulcrum plate 32.

With the above construction, the present spinning reel operates as follows. At the time of long-distance casting, the bail 13 is set to the release position to release the guide of the road yarn 16 by the guide roller 14 so that the yarn wound around the spool 4 freely comes out. Then, when the line yarn 16 is stretched after the long throw, the bail 13 is moved and the guide yarn 14 is moved by the guide roller 14.
While setting the setting knob 35 to the first or second position. As described above, at this position, the roller 6 is locked between the inner and outer races and the inner and outer races are in a clutch state.
Therefore, when tension is generated in the yarn 16 due to the resistance on the load side, the rotor 3 is rotated in the reverse direction via the guide roller 14 and this torque is transmitted to the pinion shaft 2, but the pinion shaft 2 and the inner ring 5 Are coupled to each other, the torque is transmitted to the inner ring 5, and the inner ring 5 rotates in the reverse rotation side. Then, under the action of the rotation of the inner ring 5 and the action of the disc spring 8, the rollers 6
The outer ring 7 moves in the direction in which the orbital space is narrowed through the rotation of the, the rollers 6 are locked between the inner and outer rings, and the inner and outer rings are clutched. On the other hand, since the outer ring 7 is coupled to the body 1 so as to transmit torque, the outer ring 7 does not rotate, so that the inner ring 5 also stops rotating and the delivery of the yarn 16 is stopped.
In this case, when the setting knob 35 is set to the first position, the inner and outer wheels are completely clutched, and the transmission torque is not limited. Therefore, this set position can be used, for example, for the purpose of applying excessive tension to cut the thread when the needle is caught.

Next, for example, when a large fish is caught with the setting knob 35 in the first setting position, the setting knob 3
When 5 is set to the second setting position, the twisting torque of the outer ring corresponding to that position becomes the drag torque, and when excessive tension is generated in the road thread 16 due to the pulling of the fish, the excessive torque equal to or greater than the set drag torque is released, and the thread torque is released. It can prevent breakage. FIG. 2 shows the relationship between the movement amount (or twist angle) of the outer ring and the absorption torque between the inner and outer rings. In the figure, the maximum allowable torque of the reel is M ₀ , and the movement amount of the outer ring at that time is δ _0.
Is. In this case, the torque M due to the tensile strength of the thread used
_If you try to set ₁ to 1/3 of M ₀ , as shown in the figure,
It is only necessary to select a position where the movement amount of the outer ring is δ ₁ as the second set position and set the outer ring at this position.

Further, when it is desired to take out the thread a little, for example, when the thread is too tight, the setting thread 35 can be set to the third position so that the road thread 16 can be freely paid out. Then, when the setting knob 35 is moved from the first position to the second or third position, the twisting of the outer ring 7 with respect to the inner ring 5 causes a smooth clutch between the inner and outer rings, without causing any impact, and the line 16
The feeding of can be stopped immediately.

As described above, in the present spinning reel, the three functions required for the spinning reel, namely, the rotation prevention of the rotor, the drag and the free rotation, are achieved by one clutch mechanism and its operating portion. Is being simplified.

[0023]

As described above, according to the present invention, in the invention of claim 1, the mechanism can be integrated and the structure can be simplified, and the drag torque can be accurately and constantly maintained at a constant level. There is no play in rotation, and the life of the spinning reel can be extended. In the invention of claim 2, in addition to the above, by using the lever in the position setting means to expand the movement of the setting portion, the position setting operation can be facilitated.
