Description
(1)プロペラシャフトシール、ユニバーサルジョイントシールに適用するジョイントシールにおいて、ダストリップ/グリースリップ間に窪み(等配溝)または溝(円周溝)を設定する。リップ間に窪みや溝を設けることで、リップ形状は変えずに空間容積を広げて内圧変動を緩和する。内圧変動の緩和により、正圧によるグリース漏れ、負圧による泥水侵入を抑制することができる。
(2)リップの変形に影響の小さい外周リップ間の底部に窪みまたは溝を設け、その容積を大きくする。これにより、内外周リップ間にグリースが満たされず空間ができるので、熱膨張による圧力上昇を緩和できる。空気は圧縮性流体のため、グリースに比べ、熱膨張による圧力上昇は小さい。
