Description
【発明の詳細な説明】 本発明は弛み止効果の大きい座金に関するものである。[Detailed description of the invention] The present invention relates to a washer that is highly effective in preventing loosening.
この座金の作用はナツトｌの回転による下降力で座金２
が締付部３に圧しつけられると、つる巻ばねを構成する
各線輪は２図及８図の右側の如く変形する、これにより
弛み止効果が発生する。The action of this washer is due to the downward force caused by the rotation of the nut l.
When pressed against the tightening portion 3, each wire ring constituting the helical spring deforms as shown on the right side in Figures 2 and 8, thereby producing a loosening effect.
２図の場合は上からの圧しつけ力の反力としてナツトを
押し返す力が作用して締付力を維持する事になる。３図

を現わす。ねじの弛みの原因となる振動に対して吸振性
を有する事も効果に寄与している。In the case of Figure 2, a force pushing back the nut acts as a reaction force to the pressing force from above, and the tightening force is maintained. In the case shown in Figure 3, the spring is shifted in the direction of rotation of the nut, and the deformed wire acts as a diagonal diagonal support rod to maintain the force of the detent. Since these two forces simultaneously act elastically over the entire wire ring, they are very effective in preventing loosening. The detent effect is particularly strong, and its effect is manifested by the slightest deformation of the era name method of the line ring. The ability to absorb vibrations that cause screws to loosen also contributes to the effect.
尚つる巻ばねを座金とした場合の効果は全円周の環状に
しなくてもその一部分を挿入してもつる巻ばねの特性上
からその目的は達せられる。Note that the effect of using a helical spring as a washer is that the purpose can be achieved even if a part of the washer is inserted, without making it annular around the entire circumference, due to the characteristics of the helical spring.

付部材質の軟かいもの、締付面の仕上度や平行度の悪い
所等で一層の効果を現わす。Because this washer has excellent elasticity, it is even more effective for small-diameter screws with low tightening force, soft tightening material, and places where the tightening surface has poor finish or parallelism.
