Description
(1)主軸にスリーブが固定され、このスリーブの外周を囲むようにパッキンが配置され、該パッキンを支持する金属リングを装着し、これらを収納したパッキンケースとを備えたリップシールにおいて、スリーブ外周と接触摺動するパッキン側に少なくとも一本以上の円周溝と該円周溝及び密封側に連通する複数個の縦溝を設けて構成する。
(2)更に、円周溝から大気側に連通するスリットを設けて構成する。
(3)主軸と、該主軸にスリーブが固定され、かつ該主軸の下部に固定されたランナと、内部にランナを配置すると共に主軸を挿通した固定部材と、固定部材と主軸間からの漏水を防止するリップシールを有する水車において、リップシールは、スリーブ外周と接触摺動するパッキン側に少なくとも一本以上の円周溝と該円周溝及び密封側に連通する複数個の縦溝を設けて構成する。
(4)リップシールを有する水車において、リップシールは、円周溝から大気側に連通するスリットを設けて構成する。
(rps),P:軸受面圧(Pa)である。
Claims (4)
- 主軸に固定されたスリーブと、このスリーブの外周を囲むように配置されたパッキンと該パッキンを支持する金属リングと、これらを収納したパッキンケースとを備えたリップシールであって、前記リップシールは、密封側と大気側との間に設けられ、前記スリーブ外周と接触摺動する前記パッキン側に、少なくとも一本以上の円周溝と、該円周溝及び前記密封側に連通する複数個の縦溝と、前記円周溝から前記大気側に連通するスリットを設けたことを特徴とするリップシール。
- 請求項1において、リップシールを複数段重ね、前記複数段のリップシール間に密封圧力よりも高い圧力の冷却水を供給するようにしたことを特徴とするリップシール。
- 請求項1において、前記スリットの大気側の開口面積を、前記縦溝の密封側の開口面積よりも小さくしたことを特徴とするリップシール。
- 主軸と、該主軸に固定されたスリーブと、該主軸の下部に固定されたランナと、内部に前記ランナを配置すると共に前記主軸を挿通した水車カバーと、該水車カバーと前記主軸間からの漏水を防止するリップシールを有する水車であって、前記リップシールは、密封側と大気側との間に設けられ、前記スリーブ外周と接触摺動する前記パッキン側に、少なくとも一本以上の円周溝と、該円周溝及び前記密封側に連通する複数個の縦溝と、前記円周溝から前記大気側に連通するスリットを設けて構成されていることを特徴とする水車。
