防水を目的とした低摩擦リップ式回転軸シールの開発

Shaft seals for waterproof are essential machine elements to enlarge the service life of water pumps or other mechanical products used in wet condition. There is a demand for shaft seals of water pumps used for cooling and circulation of semiconductors. Such shaft seals need high durability at high speed rotation. In this study, new shaft seal using hydrated materials has developed and conducted pressure resistant test to confirm low friction and durability. The results showed that low friction characteristics of the new shaft seal weren't susceptible to water pressure and suggested that performances of the hydrated seal lip were influenced by additives contained in water solution.
