ワール気流を補なうように構成したことを特徴と
する軸受箱に於ける潤滑油シール構造。 In labyrinth seals used in journal bearings of rotating machinery, air swirl has a spiral shape that introduces seal air flowing from the inner circumferential side to the outer circumferential side into the bearing housing in order to promote the sealing effect of lubricating oil. A passage is provided to develop a swirl air flow, and
A lubricating oil seal structure in a bearing box characterized in that two rows of sub-nozzles are provided near the outside of the labyrinth seal to efficiently support the main seal air nozzle and are configured to supplement swirl airflow.
