Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing reel having an improved drive part.

[0002]

2. Description of the Related Art Conventionally, a fishing reel is generally provided with a winding drive mechanism for winding a fishing line on a spool and a fishing line parallel winding mechanism for winding the fishing line on the spool in parallel. . The winding drive mechanism and the members constituting the fishing line parallel winding mechanism have many rotating parts and sliding parts, and the contact parts of such rotating parts and sliding parts include rolling bearings and the like. Generally, bearings are arranged so that rotation and sliding guides are light.

However, in recent years, fishing reels have been made smaller and lighter, and there are cases where bearings are abolished in the area where space is not available, giving priority to downsizing. Especially, in the sliding part (level wind mechanism of double bearing type reel, between the slider and guide pillar of the oscillating mechanism of spinning reel, between the spool shaft of the spinning reel and the pinion gear, etc.) Frictional resistance occurs between the support member and the bearings that reduce this frictional resistance.
There is no other way than increasing the size of the bearing support. In this case, if a small bearing is installed to reduce the overall size,
Particularly, between the spool shaft and the pinion gear where a load is applied, the bearing is likely to be damaged and durability is poor, so that the bearing cannot be actually incorporated.

Therefore, in order to solve the above problems, by reducing the frictional resistance between the support member and the sliding member, for example, between the pinion gear which is the supporting member and the spool shaft which is the sliding member, A configuration is known in which a spool shaft is slidably supported without play. This known configuration is
By forming a counterbore along the axial direction in the middle portion of the inner circumference of the pinion gear, the frictional resistance between the pinion gear and the spool shaft is reduced, and thus the sliding of the spool shaft is lightened.

[0005]

As described above, in the prior art, a smooth operation can be obtained by reducing the frictional resistance between the sliding member and the member in contact with the sliding member. In the actual configuration, the following problems occur.

In the above example of the pinion gear and the spool shaft, the pinion gear has a cylindrical shape with a very small diameter,
Basically, processing is performed only by cutting the inner diameter part with a tool. Normally, the processed inner diameter surface (abutment surface with the spool shaft) is left unprocessed, so there are burrs, crevices, and other processing marks left. The traces come into contact with the spool shaft, and are a cause of catching and rubbing noise during sliding.

Further, since the processing marks and burrs cause many irregularities on the surface of the contact surface, seawater and dust are likely to adhere. In this case, if seawater adheres,
Rust is likely to occur, and when dust adheres, the sliding contact surface is abraded, and the contact surface interval becomes wider than the proper clearance, resulting in rattling.

The present invention has been made on the basis of the above-mentioned problems, and it is possible to prevent catching and rubbing noise during sliding between a sliding member and a supporting member and to carry out a smooth winding operation. An object is to provide a fishing reel.

[0009]

In order to solve the above problems, a fishing reel according to the present invention comprises a winding drive mechanism for winding and holding a fishing line on a spool supported by a reel body.
In a structure including a sliding member that slides when the winding driving mechanism drives the winding, and a supporting member that supports the sliding member, a contact surface of at least one of the sliding member and the supporting member. The surface roughness of the above is smaller than the surface roughness of other parts of each member.

Usually, the processed surface after cutting a metal member or the like is in a rough state, and when another member slides on it, catching or rubbing noise is likely to occur, Seawater and dust are easily attached. As described above, when the abutting surface of the sliding member and the supporting member that supports the sliding member is processed, surface treatment is further performed so that the roughness of the abutting surface is reduced, thereby catching or rubbing. It is possible to suppress the generation of sound and to make it difficult for seawater, dust, etc. to adhere.

In the above construction, the sliding member is a member provided in the fishing reel for rotating or linearly moving, and the supporting member is fixed to the reel body or A member that includes a moving member and supports the sliding member is applicable.

The spinning reel 1 includes a reel body 2 having leg portions 2a for mounting on a fishing rod, a rotor 3 rotatably arranged in front of the reel body, and a front-rear direction synchronized with a rotational movement of the rotor 3. And a spool 5 arranged so as to be movable.

A handle shaft 7 is rotatably supported in the reel unit 2, and a handle 9 is provided at the protruding end thereof.
Is attached. A take-up drive mechanism is engaged with the handle shaft 7, and the take-up drive mechanism is attached to the handle shaft 7 and has a drive gear 10 having internal teeth.
A pinion gear 12 that meshes with the drive gear 10 and extends in a direction orthogonal to the handle shaft 7 and has therein a through hole 12a extending in the axial direction as shown in FIG.

The pinion gear 12 is
A spool shaft 15 is rotatably supported in the reel body via a bearing, and has a through hole 12a extending in a direction orthogonal to the handle shaft 7 and having a spool 5 attached to the distal end side thereof. It is movably inserted.

The pinion gear 12 has a spool 5
An oscillating mechanism that moves the (spool shaft) back and forth is engaged. The oscillating mechanism is rotatably supported in the reel body, and is fixed by a screw through a worm shaft 17 extending in parallel with the spool shaft 15 and a base plate of the spool shaft 15 via a retaining plate 18. The slider 20 and the gear 21 that is attached to the end of the worm shaft 17 and meshes with the pinion gear 12.

The pinion gear 12 extends toward the spool side, and the rotor 3 is provided at the tip thereof.
Are attached via nuts 22. Further, the pinion gear 12 has a one-way clutch 25 at its intermediate portion.
Is attached, and the one-way clutch is operated by rotating the lever 27 attached to the outside of the reel unit 2 to prevent the handle from rotating in the reverse direction.

When the handle 9 is wound up, the rotor 3 is rotationally driven through the winding drive mechanism described above, and the spool shaft 15 is slid back and forth in the pinion gear 12 through the oscillating mechanism. Therefore, the fishing line is evenly wound around the winding drum portion 5a of the spool 5 that moves back and forth via the fishing line guide portion 3a of the rotor 3.

In the above-mentioned structure, the pinion gear 12 having the spool shaft 15 and the through hole 12a is formed by processing means such as turning, boring, and reamer. The spool shaft 15 formed in this way is the pinion gear. 12
Since it is moved back and forth in the through hole 12a while being supported with respect to, the outer peripheral surface and the inner peripheral surface 12b of the through hole of the pinion gear 12 are contact surfaces that come into surface contact with each other.

According to the above-mentioned processing means, the surface is
As shown in FIG. 4, it has a concavo-convex surface shape (in the figure, the portion of the inner peripheral surface of the pinion gear 12 is shown, and the difference from that after the surface processing treatment described below is clearly shown. Therefore, the pinion gear 12 formed by such processing means is further subjected to surface processing so that the inner peripheral surface 12b thereof becomes flat. The surface processing for processing the inner peripheral surface 12b into a flat shape can be performed by grinding, buffing, or the like, but in the present embodiment, the burnishing tool 50 shown in FIGS. By using it, the surface is finished flat (vanishing processing is applied).

The burnishing tool 5 used in this embodiment
0 is a cylindrical frame 51 as shown in FIGS.
And a columnar processing amount adjusting member 52 formed in a tapered shape and arranged in the frame 51. A groove hole 51a extending in the axial direction is formed at a tip portion of the frame 51 at a predetermined interval in the circumferential direction, and the processing amount is adjusted in each groove hole 51a so as to be exposed from the frame surface. Roller 5 having the same taper as the member
3 is held so as to be rotatable and movable in the radial direction.

In this case, the width of each groove is formed narrower than the maximum diameter of the roller 53 held therein so that the roller does not fall off. Further, the processing amount adjusting member 52 having a taper can be moved in the axial direction by the propelling action of a screw (not shown). By adjusting the propulsing amount, the radial protrusion amount of each roller 53, That is, the processing state can be adjusted.

As shown in FIG. 5, the burnishing tool 50 having the above-described structure is inserted into the through hole 12a of the pinion gear 12 and the frame 51 portion thereof is rotationally driven to cause each roller 53 to move to the inner peripheral surface 12b. The surface is crushed and the uneven surface is plastically deformed to make it flat. That is, the convex portion is rolled by the roller 53 to become a concave portion, and the surface thereof is finished flat.

When the surface treatment as described above is applied, that portion has a smaller surface roughness than the surface of the other portion not subjected to the surface treatment. As shown in FIG. It has a smooth and smooth surface. Therefore, when the spool shaft 15 slides on the rotating pinion gear 12 when the fishing line is wound, the inner peripheral surface (contact surface)
In 12b, a smooth winding operation can be performed without the spool shaft being caught or making a rubbing noise. In addition, when the surface treatment as described above is performed,
It is difficult for seawater and dust to adhere, and it is possible to prevent rattling due to rust and wear. In particular, by performing the above-mentioned burnishing processing,
Since the surface is hardened, the wear resistance of the friction surface can be improved.

When the above-mentioned surface treatment is applied, it is preferable that the surface roughness is 0.2 μm or less in terms of arithmetic average roughness defined by JIS standard. In other words, if surface treatment is performed until such a state is achieved, rotation and sliding will be much smoother than with conventional products, and dimensional changes due to wear will be small, with less rattling over a long period of time. , Will be able to maintain high-precision quality. Such surface roughness can be easily obtained by the above-mentioned burnishing processing.

FIG. 10 is a view showing a modification of the above spinning reel. Pinion gear 12 of this modification
Is, as shown in FIG. 11, in the middle portion of the through hole 12a,
The counterbore 12c is formed along the axial direction, and the contact surfaces 12d at both ends thereof are brought into contact with the outer peripheral surface of the spool shaft 15 to reduce the frictional resistance between them.

The pinion gear 1 thus processed and formed
Also in No. 2, since the surface thereof is uneven as shown in FIG. 12, the burnishing tool 50 is used for the portion of the contact surface 12d as shown in FIG. As shown in FIG. 14, by performing the surface treatment on the surface of the spool shaft 15, the surface portion abutting on the spool shaft 15 is finished to be flat, and the surface is hardened to improve the hardness.

Therefore, when the spool shaft 15 slides with respect to the rotating pinion gear 12 when the fishing line is wound up, the spool shaft 15 is not caught or rubbed at the contact surface 12d, and it is smooth. It is possible to perform a winding operation. Further, in this modified example, by forming the counterbore 12c, the area of the contact surface with respect to the spool shaft 15 is reduced, so that a lighter winding operation can be performed.

In the above-described embodiment and modification, the inner peripheral contact surface of the pinion gear 12 is subjected to the burnishing process. However, the similar contact burnishing process is applied to the spool shaft side contact face. You may give a process. That is, the surface 15a of the spool shaft 15 formed by turning or the like.
15 has an uneven surface shape as shown in FIG. 15, but such a surface is further subjected to burnishing processing using the burnishing tool 60 shown in FIGS. 16 to 19, It may be finished flat.

As shown in FIGS. 16 to 19, the burnishing tool 60 for treating the surface portion of the spool shaft 15 is arranged so as to surround a cylindrical frame 61 and the frame 61 concentrically. And a cylindrical processing amount adjusting member 62 formed in a tapered shape. Groove holes 61 a extending in the axial direction are formed at a tip portion of the frame 61 at predetermined intervals in the circumferential direction.
A roller 63 is held at a so as to be exposed inward from the surface of the frame and rotatable in the radial direction.

In this case, the width of each groove is formed narrower than the maximum diameter of the roller 63 held therein so that the roller does not fall off. Further, the processing amount adjusting member 62 having a taper can be moved in the axial direction by the propelling action of a screw (not shown). By adjusting the propulsing amount, the radial protrusion amount of each roller 63, That is, the processing state can be adjusted.

As shown in FIG. 16, the burnishing tool 60 having the above-described structure is arranged so that the spool shaft 15 is inserted therethrough, and by rotating the frame 61 portion thereof,
Each roller 63 crushes the outer surface 15a of the spool shaft 15 and plastically deforms the uneven surface to flatten it. That is, the convex portion is rolled by the roller 63 so as to become a concave portion, and as shown in FIG. 20, the surface 15a is finished to be flat and the surface is hardened so that the hardness can be improved. become.

When the surface treatment as described above is applied, that portion has a smaller surface roughness than the surface of the other portion which has not been subjected to the surface treatment, resulting in a smooth and smooth surface. There is. Therefore, when winding the fishing line,
Spool shaft 1 for pinion gear 12 in rotation
When 5 slides, the spool shaft is not caught and no rubbing noise is generated, and a smooth winding operation can be performed. In addition, when the surface treatment as described above is performed,
It is difficult for seawater and dust to adhere, and it is possible to prevent rattling due to rust and wear. In particular, by performing the above-mentioned burnishing processing,
Since the surface is hardened, the wear resistance of the friction surface can be improved.

Even when the spool shaft 15 is surface-treated as described above, it is preferable that the surface roughness is 0.2 μm or less in terms of arithmetic average roughness. By performing surface processing in such a state, remarkably smooth rotation and sliding can be obtained, dimensional change due to wear is small, less rattling over a long period of time, and high precision quality can be maintained. Like

Further, it is preferable that the above-mentioned surface treatment is applied to both the outer peripheral surface of the spool shaft 15 and the inner peripheral surface of the pinion gear 12, and both contact surfaces that come into surface contact are
By performing the surface treatment as described above, it is possible to more effectively prevent the catching and rubbing noise.

The surface treatment as described above is applied to the contact surface between the sliding member provided in the fishing reel and the supporting member supporting the sliding member. ,
By applying it to parts that slide while rotating relative to each other, such as the pinion gear and the spool shaft, it is possible to effectively eliminate the occurrence of both catching and rubbing noise on the contact surfaces in different directions of rotation and sliding. As a result, a smooth and light winding operation can be easily obtained. Furthermore, in a rotating or sliding member, which is originally subject to severe abrasion due to frictional resistance, the abrasion and corrosion can be prevented, and the durability can be remarkably improved.

The portions to be subjected to the surface treatment as described above are applied to the contact surfaces at various places between the sliding member and the supporting member provided in the reel bodies of various fishing reels. For example, the spinning reel shown in FIG. 1 can be applied to the contact surface between the traverse cam shaft and the slider. Further, in the dual-bearing type reel, for example, it can be applied to the contact surface between the traverse cam shaft and the slider of the level wind mechanism.
