Title (EN) NUT
(FR) ÉCROU
(JA) ナット
Abstract:
(EN) A layered nut (10) comprises a plurality of thin nuts (12) formed with through-holes (16) having almost the same diameter. On the inner peripheral surface of each thin nut (12), a plurality of screw threads (18, 38) are formed at predetermined angular spacing so as to protrude toward the inside of the through-hole (16). In this case, the thin nuts (12) are layered along the direction of the central axis (14) so that the through-holes (16) become approximately coaxial. The outer peripheral surfaces of the layered thin nuts (12) are subjected to laser welding or the like, thereby joining the thin nuts (12) and completing the layered nut (10).
(FR) L'invention concerne un écrou à couches (10) comprenant une pluralité d'écrous minces (12) comprenant des trous traversants (16) ayant presque le même diamètre. Sur la surface périphérique interne de chaque écrou mince (12), une pluralité de filets de vis (18, 38) sont formés à un espacement angulaire prédéfini de façon à faire saillie vers l'intérieur du trou traversant (16). Dans ce cas, les écrous minces (12) sont disposés en couches le long de la direction de l'axe central (14) de sorte que les trous traversants (16) deviennent approximativement coaxiaux. Les surfaces périphériques externes des écrous minces en couches (12) sont soumises à un soudage au laser ou similaire, ce qui permet d'assembler les écrous minces (12) et d'achever l'écrou en couches (10).
(JA) 積層ナット(10)は、略同径の貫通孔(16)が形成された複数の薄形ナット(12)を有する。各薄形ナット(12)の内周面には、所定角度間隔で複数のねじ山(18、38)が貫通孔(16)の内方に突出形成されている。この場合、各貫通孔(16)が略同軸となるように、中心軸(14)の方向に沿って、各薄形ナット(12)が積層され、積層状態の各薄形ナット(12)の外周面に対して、レーザ溶接等を行うことにより、各薄形ナット(12)が接合され、積層ナット(10)が完成する。
