Abstract

New research results allow to use standard radial shaft seals reliably in rotating housings. Especially in case of fast-rotating seals, the sealing lip can lose the contact with its counterface, risking severe leakage. With a new modeling approach the critical rotational speeds can be estimated. Different new test methods for rotating radial shaft seals are presented, giving information about the operational behavior of radial shaft seals in rotating housings. The influence of the centrifugal force on the sealing system can be exploited by ensuring an efficient sealing effect while reducing the radial force during operation. Differences between the standard application with a rotating shaft are shown and the sealing quality regarding the reverse pumping ability is investigated. The results show the possibility of using rotating seals specifically for friction reduction, while providing a reliable sealing effect at the same time.
