Description
本発明による皿ねじは、皿状頭部4付きのねじ部2を有している。ねじ部の他端は不図示のねじ先端を形成している。皿状頭部4はねじ部2の方向に一定のテーパ角αをなして延びる円錐面6を有している。
ねじ部2は、少なくとも一部は円筒状の軸12と、軸12につるまき線状の突起として設けられた1条または多条のねじ山14とからなっている。ねじ山14は外側のねじ山端縁でおねじ呼び径Dを形成している。ねじ山のピッチは図1においてSで表されている。

すべての前記リブ状突片(16)の接当面(18)の面積総和は全周に及ぶ前記円錐状包絡面の面積の少なくとも40%から60%までの範囲内にあることを特徴とする皿ねじ。 - すべての前記リブ状突片(16)の接当面(18)の面積総和は前記リブ状突片(16)の間に位置する領域の面積総和にほぼ等しいことを特徴とする請求項1に記載の皿ねじ。
- 前記テーパ角(α)は50°〜60°の範囲内にあることを特徴とする請求項1又は2に記載皿ねじ。
- 前記テーパ角(α)は53°〜55°の範囲内にあることを特徴とする請求項1又は2に記載の皿ねじ。
- 前記円錐角(β)は90°であることを特徴とする請求項1〜4の何れか一項に記載の皿ねじ。
- 前記リブ状突片(16)は前記皿状頭部(4)の外周(20)領域から出発して実質的に径方向に延びて、少なくとも、前記ねじ部(2)のねじ山(14)を軸方向に投影した箇所(22)にまで達していることを特徴とする請求項1〜5の何れか一項に記載の皿ねじ。
- 同一の形状を有した3〜8個の前記リブ状突片(16)が外周に均等に放射対称配置されて設けられていることを特徴とする請求項1〜6の何れか一項に記載の皿ねじ。
- 同一の形状を有した6個の前記リブ状突片(16)が外周に均等に放射対称配置されて設けられていることを特徴とする請求項1〜6の何れか一項に記載の皿ねじ。
- 各前記リブ状突片(16)はその接当面(18)の形状において実質的に円弧状断面を有し、径方向に延びる側面(24,26)を有していることを特徴とする請求項1〜8の何れか一項に記載の皿ねじ。
- 各前記リブ状突片(16)は円周方向において2側面(24,26)によって境界付けられており、各側面(24,26)は根元で隣接する面との間に90°以上のフランク角(φ1;φ2)を形成していることを特徴とする請求項1〜9の何れか一項に記載の皿ねじ。
- 螺入方向(34)への回転時に前方を向く側面(24)は90°〜95°の範囲内の前記フランク角(φ1)を有する一方で、他方の側面(26)は95°以上の前記フランク角(φ2)を有することを特徴とする請求項10に記載の皿ねじ。
- 前記ねじ部(2)は、少なくとも一部は円筒状の軸(12)と、突起として前記軸(12)を巻回るねじ山(14)とからなることを特徴とする請求項1〜11の何れか一項に記載の皿ねじ。
- 前記ねじ山(14)は35°のリード角(γ)を有することを特徴とする請求項12に記載の皿ねじ。
- 前記ねじ山(14)は、おねじ呼び径(D)の60%に相当するピッチ(S)を有することを特徴とする請求項12又は13に記載の皿ねじ。
