Description
間に半径方向シールを形成するために、結合部の各端部の近くの溝内に位置付けられた圧力エネルギー付与型エラストマーシールである。
するように構成され、その逆も然りであり、そこでは該シールリングは組み入れの時及びその後の何れに於いてもハウジングと共働して動作する。
1つの側面では溝13は、リング6の内面のより容易な圧搾を可能にすることに必要な半径方向変形を提供する空白部として作用し、
もう1つの側面ではリブ11,12が負荷集中をもたらし、これによりシール用の接触を増やし、二つの独立したシール用のバリヤとして作用する、ことをもたらす。
α>βで、かつ
γ>δ
が充たされる様な大きさを有する様に選ばれる。
Claims (1)
- ピンとして規定される雄ねじチューブ(2)、ボックスとして規定される雌ねじチューブ(3)、該ピン及び該ボックスの間に間挿されるシールリング(6)を具備し、該ピンが該ボックス内に組み入れられるように構成され、該シールリングはねじ部分(5)の端部と該ボックス(3)のノーズ(15)との間の該ボックス(3)の表面の部分に配置され、そして外面(11,12,13)を介して該ボックス(3)の内面と緊密にシール接触し、内面(10,19,20)を介して該ピン(2)の外面と緊密にシール接触をしており、
該シールリング(6)は、
実質的に平面である第1ベース(8)と、
該第1ベースと軸線方向に相対する第2ベース(9)と、
該外面上の少なくとも2つの突出する環状リブ(11,12)と、を備えており、
前記シールリング(6)の該内面が、無負荷位置で該シールリングの中央の方へ傾斜が付けられ、かつフィレット(10)により接合された2つの円錐台形環状面(19,20)を有しており、
前記円錐台形環状面(19,20)が下記関係を充たす値を有する、軸線に垂直な面に対する傾斜角α、γを備え、
α>βそして
γ>δ
ここでβはねじの進み側の傾斜角であり、δはねじの追い側の傾斜角であり、
該シールリングの軸線方向の厚さ“t”がねじの2つの頂上の間の間隔“b”より大きく、
該シールリング(6)のボデイの内部に強化リング(7)が設けられ、
該シールリング(6)がエラストマー材料製であり、
前記円錐台形環状面(19,20)が等しい値または異なる値のいずれかのそれぞれの傾斜角α、γを有し、
