Abstract

A new method for estimating the critical speeds of standard radial shaft seals in rotating housings is described. Based on static radial force measure-ments, the analytical approach showed good re-sults for estimating the rotational speed at which the sealing lips lift off. With thisinformation,stand-ard radial lip seals can be used in applications with rotating housings appreciably reducing the risk of heavy leakage. The contributionof the centrifugal force can be used to decrease the friction torque without impairing sealing performance. Furthermore,the effect of different oil levels in-side the rotating housing is shown. Higheroillevelslead to a higher friction torque because of the addi-tional radial force component due to theoil pressureexertedon the sealing lip.
