【考案の詳細な説明】
この考案はボルトナツトの締結時に用いられるスプリン
グワッシャーに関するものである。[Detailed Description of the Invention] This invention relates to a spring washer used when fastening bolts and nuts.
一般にボルトを嵌挿してナツトで固定する被締付部材に
縮みあるいはへたりが生じるとナツトの緩みの原因とな
り、ナツトの緩みを防止するためには、何らかのダンパ
一手段が必要となる。Generally, if a tightened member into which a bolt is inserted and is fixed by a nut shrinks or sag, it causes the nut to loosen, and in order to prevent the nut from loosening, some kind of damper means is required.
通常このようなダンパ一手段として広く採用されている
ものに皿ワッシャーまたは一回ねじりのコイルワッシャ
ー等があるが、これらの弾発力は一様でなく、ある程度
の縮め方向力の限界を超えたときに弾発するものである
から、極めて小さい範囲内で被締付部材が伸縮するもの
にあっては的確に追従できないという欠点がある。Generally, countersunk washers or single-twist coil washers are widely used as such damper means, but the elastic force of these is not uniform and exceeds the limit of the compressive force to a certain extent. Since it sometimes springs, there is a drawback that it cannot follow accurately if the member to be tightened expands or contracts within an extremely small range.
この考案は設定されたストローク内で極めて有効に働く
スプリングワッシャーを提供せんとするもので、以下に
その詳細を添付図面にもとづいて述べる。This invention aims to provide a spring washer that works extremely effectively within a set stroke, and its details will be described below based on the accompanying drawings.
１はボルト、２，３はナツト、４，５は被締結部材であ
る。1 is a bolt, 2 and 3 are nuts, and 4 and 5 are members to be fastened.
本考案に係わるスプリングワッシャーは、ボルト１を嵌
挿する孔６を有する皿型の可動部材７と、この内部に設
けたコイルスプリング群８と、固定部材９とから構成さ
れている。The spring washer according to the present invention is composed of a plate-shaped movable member 7 having a hole 6 into which a bolt 1 is inserted, a coil spring group 8 provided inside the movable member 7, and a fixed member 9.
可動部材７は外周縁部に環状をなす周縁突起７ａを有し
ている。The movable member 7 has an annular peripheral protrusion 7a on its outer peripheral edge.
さらに可動部材７は、この考案において必須ではないが
スプリングの配置を容易にするために、内周縁部にも補
強的な比較的短い他の周縁突起７ｂをも有している。Furthermore, the movable member 7 also has another relatively short reinforcing peripheral protrusion 7b on the inner peripheral edge, although this is not essential in this invention, in order to facilitate the arrangement of the spring.
上記両局縁突起７ａ、７ｂ間に形成される環状凹部に複
数の前記スプリング８が、例えば第２図に示すごとく１
噌円周方向に配列されている。A plurality of springs 8 are installed in the annular recess formed between the two edge protrusions 7a and 7b, for example, as shown in FIG.
They are arranged in the circumferential direction.
該複数のスプリングは、可動部材７と固定部材９との間
で作用する力が円周方向に均一になるように、円周方向
に等間隔で配置されるのが望ましい。The plurality of springs are desirably arranged at equal intervals in the circumferential direction so that the force acting between the movable member 7 and the fixed member 9 is uniform in the circumferential direction.
各スプリングはリテイナ−１０によって上記等間較の位
置に保持される。Each spring is held in the equidistant position by a retainer 10.
また該可動部材の外周突起７ａの外周先端には段部１１
が形成され、この段部１１にリンク１２が嵌着されてい
る。Further, a stepped portion 11 is provided at the outer circumferential tip of the outer circumferential protrusion 7a of the movable member.
is formed, and a link 12 is fitted into this stepped portion 11.
この可動部材７の外側に嵌着されるキャップ状の固定部
材９は有底で中心に孔１３を有し、外周縁突起１４の内
側に段部１５を形成して前記リング１２によって両者が
抜は止め状となっている。A cap-shaped fixed member 9 fitted on the outside of the movable member 7 has a bottom and a hole 13 in the center, and has a step 15 formed inside the outer peripheral protrusion 14 so that both can be pulled out by the ring 12. It has become a stop sign.
したがってリング１２と段部１５との間隔がワッシャー
のストロークとなる。Therefore, the distance between the ring 12 and the stepped portion 15 is the stroke of the washer.
この考案は以上の構成によるから、−個のワッシャーが
生ずる荷重Ｆは各スプリング８の力をＲとすれば、Ｆ
＝＝ｎＲ（１１＝スプリング数）であられされ、極めて
大荷重のものが得られる。Since this invention has the above configuration, the load F generated by the - washers is calculated as F if the force of each spring 8 is R.
==nR (11=number of springs), and an extremely large load can be obtained.
本実施例ではストローク範囲がｌ〜２ｒｒａｎ範囲でス
プリングの力を４０ｋｇとすれば６４０ｋｇの力が得ら
れることになる。In this embodiment, if the stroke range is 1 to 2 rran and the spring force is 40 kg, a force of 640 kg will be obtained.
特に被締付部材４がその範囲内で伸縮するものにおいて
極めて多大な効果を発揮する。This is especially effective when the tightened member 4 expands and contracts within that range.
