Embodiment Construction

[0028] Selected embodiments of the invention will now be described with reference to the accompanying drawings. It will be apparent to those skilled in the art from this specification that the following descriptions of the embodiments of the present invention are for illustration purposes only and not as limitations of the invention as defined by the appended claims and their equivalents.

[0029] Such as figure 1 and figure 2 As shown, the double-bearing reel adopting the sealing mechanism of an embodiment of the present invention is a small reel for electric poles. This reel comprises a reel unit 1, a spool rotating handle 2 mounted on one side of the reel unit 1 and a reel 12 for winding fishing line as the handle 2 rotates. Rotatable and detachably mounted on the inner side of the reel unit 1 . A spider 3 for adjusting the traction is arranged on the same side of the reel unit 1 as the crank 2 .

[0030] The crank 2 is of a double crank type and has a plate-shaped cra...

Abstract

A rotation support structure for a dual-bearing reel includes a reel unit, a spool shaft, and fluid bearings. The spool shaft is disposed on an inner circumferential side of the reel unit and can rotate relative to the reel unit. The fluid bearings have a plurality of grooves for forming a fluid lubricant film between the reel unit and the spool shaft. The rotation support structure is provided for a high-speed rotation operation of a dual-bearing reel, with which a reduction of the rotation performance during high-speed rotation can be successfully suppressed.

Description

technical field [0001] The present invention generally relates to support structures. In particular, the present invention relates to rotational support structures for high speed rotating components of dual bearing reels. Background technique [0002] Double bearing reels and especially swing rod reels and electric drive reels are equipped with high speed rotating parts. In the case of a swing reel, the spool rotates at a high speed of about 2000 rpm while the swing is being carried out. To support components rotating at high speeds, ball bearings are generally used as rolling bearings. [0003] When a ball bearing is used as a supporting structure for a rotating part, since the ball bearing has small rotational resistance, the rotational performance will be reduced. For example, if the spool of the swing reel is supported by ball bearings, the flight distance will be reduced due to rotational resistance during the swing. Conventionally, to solve this problem, a contact ...
