Description

Technical Field

[0001] The utility model relates to a fishing reel, in particular to a device for reducing the axial clearance of a gear disc shaft of the fishing reel. Background Art

[0002] When using a water drop fishing reel to cast and reel in, the rocker arm drives the large chainring and a series of parts to rotate around the axis of the chainring shaft through the chainring shaft, and no movement in other directions is allowed. Since there is clearance between the inner and outer rings and the balls of the bearings on the chainring shaft, the chainring shaft and the fishing reel body will have axial margin, resulting in axial shaking. If there is shaking or margin in other directions, the feel of use will deteriorate. Due to manufacturing errors and assembly errors of parts, gaps and margins always exist.

[0003] To solve this problem, the common solution is to improve the processing accuracy and fitting accuracy as much as possible, and reduce the shaking except for rotation to below the threshold that cannot be perceived by human touch. However, this solution has high manufacturing and maintenance costs and is more likely to cause shaking after wear. Utility Model Content
