TECHNICAL FIELD OF THE INVENTION
The present invention relates to a support structure for a fishing reel, and more particularly to a support structure for supporting a member provided on a fishing reel.
[0002]
[Prior art]
A high-speed rotating component is mounted on a fishing reel, in particular, a dual-bearing reel such as a bait casting reel or an electric reel. In the case of a bait casting reel, the spool rotates at a high speed of about 20,000 revolutions per minute during casting. When supporting such high-speed rotating parts, it is difficult to directly support them with ball bearings due to noise and rotational resistance problems. The slip is caused to occur. At low load and high speed rotation, it is desirable to increase the degree of support by the slippage for quietness, but at the same time, seizure easily occurs between the inner ring of the bearing and the rotating parts. If the bearings and rotating parts are seized, the rotational performance is extremely deteriorated.
[0003]
Therefore, in order to prevent seizure of the bearing and the rotating component, there is known an oil reservoir in which a groove for an oil reservoir is formed along a circumferential direction on a relative rotation surface of either the bearing or the rotating component. By injecting oil into the groove, seizure of the bearing and the rotating component can be prevented even when the rotating component rotates at high speed.
[0004]
[Problems to be solved by the invention]
In the rotation support structure using the conventional bearing, a groove for an oil reservoir is formed in the bearing and the rotating component along a circumferential direction. Therefore, seizure of the bearing and the rotating component can be prevented, and since the groove is formed along the circumferential direction, it is difficult for oil to escape to the outside. However, when lubricating the groove with oil from the outside or performing maintenance work for removing salt precipitated by the adhesion of seawater to the groove, the rotating parts must be removed from the bearing. For this reason, maintenance work is troublesome and inconvenient.
[0005]
Then, it is possible to form a groove part along an axial direction. When the groove is formed along the axial direction, the end of the groove is exposed to the outside, so that it is easy to lubricate the groove from the outside and remove salts. However, if the groove is formed along the axial direction, for example, in the shape of a key groove or a spline, machining of the groove becomes difficult.
SUMMARY OF THE INVENTION It is an object of the present invention to provide a fishing reel support structure in which maintenance work can be performed easily and seizure of rotating parts can be prevented by simple processing.
[0006]
[Means for Solving the Problems]
A support structure for a fishing reel according to a first aspect of the present invention is a support structure for supporting a member provided on the fishing reel, comprising: a first member; a second member rotatable relative to the first member; An oil sump groove formed helically on at least one of the relative rotation surfaces of the first member and the second member.
[0007]
In this support structure, a spirally formed oil reservoir groove is formed on at least one of the relatively rotating surfaces of the first member and the second member that rotate relatively. Here, seizure of the first member and the second member can be prevented by injecting oil into the groove formed in at least one of the first member and the second member. Further, since the groove is formed in a spiral shape, the end of the groove is exposed to the outside, and maintenance work for lubricating the groove and removing salt from the outside is facilitated. Furthermore, if the groove is formed in a spiral shape by, for example, threading, the groove can be formed by simple processing. Therefore, the maintenance work can be easily performed, and the burn-in of the rotating component can be prevented by the simple processing.
[0008]
A support structure for a fishing reel according to a second aspect of the present invention is the support structure according to the first aspect, wherein the groove is formed by threading. In this case, since the groove is formed in a spiral shape by thread cutting, the processing of the groove is facilitated.
According to a third aspect of the invention, there is provided a fishing reel support structure according to the first or second aspect, wherein the groove is formed in the first member. Here, for example, when the second member that rotates relative to the first member that is non-rotatably mounted is a rotating component, a groove is formed in the first member that does not rotate.
[0009]
A fishing reel support structure according to a fourth aspect of the present invention is the support structure according to any one of the first to third aspects, wherein the groove is formed in the second member. Here, for example, when the second member that rotates relative to the first member that is non-rotatably mounted is a rotating component, a groove is formed in the rotating second member.
A support structure for a fishing reel according to a fifth aspect of the present invention is the support structure according to any one of the first to fourth aspects, wherein the first member is a spool shaft of the fishing reel, and the second member is an inner ring of a bearing. In this case, by forming a spiral groove on at least one of the relative rotation surfaces of the spool and the inner ring of the bearing, maintenance work can be performed easily, and seizure of the spool and the inner ring of the bearing can be prevented by simple processing. it can.
[0010]
A support structure for a fishing reel according to a sixth aspect of the present invention is the support structure according to any one of the first to fourth aspects, wherein the first member is a gear shaft of the fishing reel, and the second member is a gear. In this case, by forming a spiral groove on at least one of the relative rotation surfaces of the gear shaft and the gear, maintenance work can be performed easily, and seizure of the gear shaft and the gear can be prevented by simple processing.
