Abstract:
(EN) Provided are: a low-cost locking screw that, with a simple configuration, reliably exhibits a nut-locking function; and a method for manufacturing the screw. Flank surfaces 22 of a screw thread 18 of a male screw 10 are designed such that an angle γ of a thread angle, which is the angle formed by flank surfaces 22 adjacent to each other on the root side of a screw groove 20, and an angle δ of a screw tip angle, which is the angle formed by flank surfaces 22 that face each other in the screw groove 20 in a crest 18a side of the screw thread 18, are different from each other. The angle δ of the screw tip angle is greater than the angle γ of the thread angle. Each flank surface 22 of the screw thread 18 is designed such that a root-side flank surface 22a, which is the surface on the root side of the screw groove 20, and a crest-side flank surface 22b, which is the surface on the crest 18a side of the screw thread 18, are noncontinuous. Flank border lines 24, which are the borders between the noncontinuous root-side flank surfaces 22a and crest-side flank surfaces 22b, are formed in an undulating shape in the flank surfaces 22 at prescribed cycles.
(FR) L'invention concerne : une vis de blocage à faible coût qui, avec une configuration simple, présente de manière fiable une fonction de blocage d'écrou ; et un procédé de fabrication de la vis. Les surfaces de flanc (22) d'un filetage (18) d'une vis mâle (10) sont conçues de telle sorte qu'un angle γ d'un angle de filetage, qui est l'angle formé par des surfaces de flanc (22) adjacentes l'une à l'autre sur le côté racine d'une rainure de vis (20), et un angle δ d'un angle de pointe de vis, qui est l'angle formé par des surfaces de flanc (22) qui se font face dans la rainure de vis (20) dans un côté crête (18a) du filetage (18) de vis, sont différents l'un de l'autre. L'angle δ de l'angle de pointe de vis est plus grand que l'angle γ de l'angle de filetage. Chaque surface de flanc (22) du filetage (18) de vis est conçue de telle sorte qu'une surface de flanc côté racine (22a), qui est la surface sur le côté racine de la rainure de vis (20), et une surface de flanc côté crête (22b), qui est la surface sur le côté crête (18a) du filetage (18), ne sont pas continues. Des lignes de bord de flanc (24), qui sont les bordures entre les surfaces de flanc côté racine (22a) non continues et des surfaces de flanc côté crête (22b), sont formées selon une forme ondulée dans les surfaces de flanc (22) au niveau de cycles prescrits.
(JA) 簡単な構成で、確実にナットの緩み止め機能を発揮し、コストも安価な緩み止めネジとその製造方法である。雄ネジ10のネジ山18のフランク面22は、ネジ溝20の谷底側で互いに隣接するフランク面22が成す角度である谷角の角度γと、ネジ山18の頂部18a側においてネジ溝20で互いに対面するフランク面22の成す角度であるネジ先角の角度δが異なる。ネジ先角の角度δが谷角の角度γより大きい。ネジ山18のフランク面22は、ネジ溝20の谷底側の面である底側フランク面22aと、ネジ山18の頂部18a側の面である頂部側フランク面22bが不連続である。不連続な底側フランク面22aと頂部側フランク面22bの境界であるフランク境界線24が、所定の周期でフランク面22に波状に形成されている。
