従来、 ナットの使用中に緩みの発生を防止する手段として、 ナット自体に色々 な工夫を加えたものが各種提案されている。 例えば、 ナットボディが一つのもの として、 ナツトボディに金属弾性板やナイロンプレート或いはスプリング等の弹 性体を組み込んだものが一般に知られている。 In the past, various means have been proposed to prevent nuts from loosening during use, by adding various ideas to the nuts themselves. For example, as a single nut body, a nut body incorporating an elastic body such as a metal elastic plate, a nylon plate, or a spring is generally known.
しかし、 このような構造のものは何れもナツトボディに 2次加工で工作をして 付加部品を組み込むものであるから、 製作が面倒でコストが高くつくと共に、 ボ ルトへのねじ込み当初から組み込まれた弾性体によって高トルクが付加されて締 め付け作業が面倒であり、 しかも使用中に弾性体の径年変化によって緩み止め効 果が劣化する、 といった欠点がある。 However, in all of these structures, secondary parts are machined into the nut body and additional parts are incorporated, which makes the production troublesome and expensive, and was incorporated from the beginning of screwing into the bolt. The high torque is applied by the elastic body, and the tightening work is troublesome, and furthermore, the loosening effect is deteriorated due to the aging of the elastic body during use.
そこで本発明は、 同時に使用されるヮッシャに工夫を加えることによって、 従 来のスタンダードナットに強力な緩み止め効果を発揮させることのできるヮッシ ャを従来のヮッシャと殆ど変わらないコストで提供することを主たる目的とする ものである。 Therefore, the present invention is to provide a hash capable of exerting a powerful locking effect on a conventional standard nut at a cost that is almost the same as that of a conventional washer by modifying the washer used simultaneously. Its primary purpose.
本発明のもう一つの重要な目的は、 上記ヮッシャを使用したナツトの緩み止め 構造を提供するにある。 Another important object of the present invention is to provide a nut locking structure using the above-mentioned washer.

That is, in the locker for preventing loosening according to the present invention, at least one surface of the upper and lower surfaces of the ring-shaped washer body 2 having the bolt 1 and the through hole 1 penetrating the shaft core is gently inclined in one direction. The structure was formed on the surface. In the washer of the present invention, when the nut B is screwed together with the washer A to the bolt D and tightened to the member C to be tightened with a predetermined torque, the lower surface of the nut B Is in close contact with the upper surface of the washer A, and the inclined seating surface 3 is pressed against the upper surface of the member C to be tightened. The angle is set within the range of possible angles.
また、 本発明では軸芯を貫通するボルト挿通孔 1を備えたリング状のヮッシャ ボディ 2の上下面の少なくとも一方の座面 3を一方向に傾く緩やかな傾斜面に形 成してヮッシャ Aを構成し、 このヮッシャ Aをナツト Bの下面に置いてナツト B をボルト Dに螺合して被締め付け部材 Cに対して所定のトルクで締め付けること により、 ナット Bの下面をヮッシャ Aの上面に密接させると共に、 ヮヅシャの傾 斜座面 3を被締め付け部材 Cの上面に圧接させ、 これによりボルト軸方向への圧 力と被締め付け部材 Cに対する面圧とを同時に発生させてナツトの緩みを防止す るようにしたナツ卜の緩み止め構造も特徴とする。 図面の簡単な説明 Further, in the present invention, at least one of the upper and lower seating surfaces 3 of the upper and lower surfaces of the ring-shaped washer body 2 having the bolt insertion holes 1 penetrating the shaft core is formed as a gentle inclined surface which is inclined in one direction to form the washer A. The nut B is screwed to the bolt D and tightened to the tightened member C with a predetermined torque, so that the lower surface of the nut B is tightly attached to the upper surface of the nut A. At the same time, the inclined seat surface 3 of the shaft is pressed against the upper surface of the member C to be tightened, thereby simultaneously generating the pressure in the axial direction of the bolt and the surface pressure against the member C to be tightened to prevent the nut from loosening.

After the nut B is screwed along the bolt D toward the member C to be tightened to bring the washer A into contact with the upper surface of the member C to be tightened, the nut B is further tightened to a predetermined torque. The nut B is fixed in the inclined posture along the inclined seat surface 3 of the washer A while filling the gap between the bolt and the nut, and the gap between the nuts. In this state, as shown by the arrow in Fig. 4, the screw on the upper side of the nut B and the screw on the lower side press the bolt side in the cutting direction, and at the same time, the inclined seat surface 3 is tightened. Pressure contact with the upper surface of member C by surface contact. Due to this internal stress, the engagement between the nut B and the screw of the bolt D is firmly locked, so that the nut B can be prevented from becoming loose.
尚、 本発明者が、 外径 2 6 im、 内径 1 2 . 2匪、 最大厚み 2 . 8 mm, 最小厚み 1 . 8 mm (この場合、 座面角ひは 2 . 3度となる） の M 1 2ナット用鉄製ヮヅシ ャを作成して、 第三者の試験センターにナット緩み振動試験を依頼した結果、 ス タンダードナツト 4個が何れも 2 0秒以内で緩んだのに対し、 試験サンプル 4個 を使用したナツトは何れも 1 4分以上の振動に耐えることができた。 尚この場合 のナツ卜の締め付けトルクは何れも 5 0 O kgf . cmであった。 In addition, the inventor of the present invention has an outer diameter of 26 im, an inner diameter of 12.2, a maximum thickness of 2.8 mm, and a minimum thickness of 1.8 mm (in this case, the seat angle is 2.3 degrees). An iron shell for M12 nuts was created, and a third-party test center was asked to perform a nut loosening vibration test.As a result, all four standard nuts loosened within 20 seconds. All four nuts were able to withstand more than 14 minutes of vibration. In this case, the tightening torque of the nut was 50 O kgf .cm.
以上本発明の一実施例について説明したが、 本発明は必ずしもこれらの実施例 構造のみに限定されるものではない。 例えば上記実施例では、 傾斜面をヮッシャ ボディの下面に設けたが上面に設けてもよく、 或いは上下面に対称的に設けても 同様な効果が得られるものである。 またヮッシャ材料も、 鉄やステンレス等の金 属材料に限らず、 小サイズのものでは合成樹脂材料で形成することも可能である ヮッシャの形状も円形に限らず六角形や 4角形等任意の形態で形成してもよい。 その他本発明ではその構成要件を備え、 かつ本発明の目的を達成し、 下記の効果 を奏する範囲内において適宜改変して実施できるものである。 Although the embodiments of the present invention have been described above, the present invention is not necessarily limited to the structures of these embodiments. For example, in the above embodiment, the inclined surface is provided on the lower surface of the washer body. However, the same effect can be obtained by providing the inclined surface on the upper surface or symmetrically on the upper and lower surfaces. In addition, the washer material is not limited to metal materials such as iron and stainless steel, and a small-sized one can be formed of a synthetic resin material.The shape of the washer is not limited to a circle, but may be any shape such as a hexagon or a quadrangle. May be formed. In addition, the present invention has the structural requirements, achieves the object of the present invention, and can be appropriately modified and implemented within the range of achieving the following effects.
以上詳述したごとく本発明によれば、 ヮッシャボディの上下面の少なくとも一 方の面に傾斜面を形成したものであるから、 製作も簡単にできて、 従来のスタン ダ一ドヮッシャと殆ど変わらない価格で提供することができるものでありながら、 スタンダードナツ卜と併用することによって、 ナツトボディ内部にボルト軸方向 への内部応力と座面への面圧とを発生させて、 確実な緩み止め効果が発揮するこ とができ、 更にはナツトのボルトえの螺入がスタンダードナツトと全く同じよう に軽く螺入させることができるから作業効率がよい、 といつた種々の優れた効果 がある。 As described above in detail, according to the present invention, since the inclined surfaces are formed on at least one of the upper and lower surfaces of the washer body, the production can be simplified, and the price is almost the same as that of the conventional standard dozer. Although it can be provided with a standard nut, it can be used together with a standard nut to generate internal stress in the bolt axis direction inside the nut body and surface pressure on the bearing surface, so that a reliable locking effect is exhibited. In addition, the bolts of the nuts can be lightly screwed in exactly the same way as the standard nuts, so that there are various excellent effects such as good work efficiency.
