Abstract
Description
軸の外周に設けられた環状溝に装着され、相対的に回転する前記軸とハウジングとの間の環状隙間を封止して、流体圧力が変化するように構成されたシール対象領域の流体圧力を保持するシールリングであって、
前記環状溝における低圧側の側壁面に対して摺動するシールリングにおいて、
前記側壁面に対して摺動する摺動面側には、径方向の幅が一定で周方向に伸びる第1溝と、第1溝における周方向の中央の位置から内周面に至るまで伸び、密封対象流体を第1溝内に導く第2溝とを有する動圧発生用溝が設けられており、
第1溝は、前記側壁面に対して摺動する摺動領域内に収まる位置に設けられていることを特徴とする。
図1~図12を参照して、本発明の実施例に係るシールリングについて説明する。図1は本発明の実施例1に係るシールリングの側面図である。なお、図1は、シールリングにおける摺動面とは反対側の側面を示している。図2は本発明の実施例1に係るシールリングを外周面側から見た図である。図3は本発明の実施例1に係るシールリングの側面図である。なお、図3は、シールリングにおける摺動面側の側面を示している。図4は本発明の実施例1に係るシールリングの側面図の一部拡大図である。なお、図4は図3のうち合口部110が設けられている付近を拡大した図である。図5は本発明の実施例1に係るシールリングの模式的断面図である。なお、図5は図3中のAA断面図である。図6は本発明の実施例1に係るシールリングの模式的断面図である。なお、図6は図3中のBB断面図である。図7は本発明の実施例1に係るシールリングの使用時の状態を示す模式的断面図である。なお、図7中のシールリングは、図3中のAA断面図である。図8~図12は本発明の実施例1に係るシールリングの模式的断面図である。なお、図8~図12は図4中のCC断面図である。
本実施例に係るシールリング100は、軸200の外周に設けられた環状溝210に装着され、相対的に回転する軸200とハウジング300(ハウジング300における軸200が挿通される軸孔の内周面)との間の環状隙間を封止する。これにより、シールリング100は、流体圧力(本実施例では油圧)が変化するように構成されたシール対象領域の流体圧力を保持する。ここで、本実施例においては、図7中の右側の領域の流体圧力が変化するように構成されており、シールリング100は図中右側のシール対象領域の流体圧力を保持する役割を担っている。なお、自動車のエンジンが停止した状態においては、シール対象領域の流体圧力は低く、無負荷の状態となっており、エンジンをかけるとシール対象領域の流体圧力は高くなる。また、図7においては、図中右側の流体圧力が左側の流体圧力よりも高くなった状態を示している。以下、図7中右側を高圧側(H)、左側を低圧側(L)と称する。
特に、図7を参照して、本実施例に係るシールリング100の使用時のメカニズムについて説明する。図7は、エンジンがかかり、シールリング100を介して、差圧が生じている状態(図中右側の圧力が左側の圧力に比べて高くなった状態)を示している。エンジンがかかり、差圧が生じた状態においては、シールリング100は、環状溝210の低圧側(L)の側壁面211及びハウジング300の軸孔の内周面に対して密着した状態となる。
本実施例に係るシールリング100によれば、動圧発生用溝120内に密封対象流体が導かれる。そのため、動圧発生用溝120が設けられている範囲においては、高圧側(H)からシールリング100に対して作用する流体圧力と低圧側(L)からシールリング100に対して作用する流体圧力が相殺される。これにより、シールリング100に対する流体圧力(高圧側(H)から低圧側(L)への流体圧力)の受圧面積を減らすことができる。
図13~図19は、本発明の実施例2が示されている。本実施例においては、動圧発生用溝について、第1溝のうち第2溝と繋がる部分の深さを、第2溝の深さと同じにし、かつ、第1溝における第2溝と繋がる部分以外の部分の深さよりも深く構成した場合の構成を示す。その他の構成および作用については実施例1と同一なので、同一の構成部分については同一の符号を付して、その説明は省略する。
