日本設計師發明「滾滑式防松螺栓/螺帽/墊片」
(圖取自金屬產業新聞)日本金屬產業新聞社報導，神奈川縣的一位設計師岡和富先生所開發的「滾滑式防松螺栓/螺帽/墊片」(專利申請中)透過球狀化的座面來防止松脫，此設計已在7月完成實驗，正在募集合作的授權制造商和模具制造商。
垂直于螺紋軸部重復發生的震動會使螺帽旋轉而發生松脫的現象，「滾滑式防松螺栓/螺帽/墊片」能透過「承受力道」以及「放掉力道」來發揮防松的效果。它的設計採用庫侖定律，設置了球狀的座面，在發生了震動可能導致松脫的時候，球狀座面會比螺紋還要先滑脫以釋放掉力道。
Japanese Designer Invents Slip Type Anti-loosening Bolt/Nut/Washer
(Picture courtesy of KINZOKU SANGYO SHIMBUNSHA)KINZOKU SANGYO SHIMBUNSHA (Japanese newspaper) reports that a designer named Kazutomi Oka from Kanagawa Prefecture of Japan developed the patent-pending "Slip Type Anti-loosening Bolt/Nut/Washer" utilizing spherical seating surface to prevent loosening. This design has completed testing this July. The designer is seeking licensee makers and die makers for collaboration.
The repeating vibration perpendicular to the thread axis causes the nut to rotate and leads to loosening. "Slip Type Anti-loosening Bolt/Nut/Washer" can prevent loosening by "bearing" and "releasing" forces. Its design utilizes Coulomb's law of friction and comes with a spherical seating surface. When vibration occurs that may lead to loosening, the spherical seating surface will slip before the threads do in order to release the force of vibration.
