    Abstract

    Tangential deformations of the seal surface at the contact zone between a shaft and a radial lip seal are determined by image analysis of video camera pictures. These displacements are thought to be essential for the sealing mechanism. The results show that all seals tested have an asymmetric pattern of tangential deformation, which is of the order of 10 micrometers. Local fluid film thickness has been studied on a separate test rig. This rig employs a new method for distance measurements in the shaft/seal contact, based on an opto electronic system as used in CD players. The preliminary results indicate that the investigated seal has a film thickness of the order of 1 micrometer under normal operational conditions, which is much higher than expected. Possible causes and improvements are discussed.
