フェースギヤ適用事例

－釣用リールへの展開と今後の方針－

Fishing reels are required to have functions such as design, drag performance, and cast feeling, and there is a particularly high demand for gear feeling (fishing reel sensation). It is said that the ultimate angler can read the difference in water quality of the day and the behavior of fish approaching the lure by the feeling of reeling from the handle. To meet this demand, reels are required to have a smooth fishing reel sensation. However, when the reel handle is rotated, vibration occurs due to the meshing of the gear pair, and if the vibration is large, smooth fishing reel sensation is hindered. The precision required by anglers is at the micrometer level, and ordinary processing machines and measuring machines cannot achieve and measure the required precision. This report describes the background and process that were developed with the aim of improving the fishing reel sensation, i.e., "Method of 3D tooth flank modification for the face gear'', "Method of precision measurement for the face gear'' and "Method of precision cold forging for the face gear".
