Abstract
A seal assembly is for sealing a rotating device and includes a dynamic seal component frictionally engageable with a device rotor and a static seal component frictionally engageable with a device stator. The two seal components are formed therebetween with a contact seal based on a sealing lip and a non-contact seal based on a labyrinth gap. The labyrinth gap is located upstream of the sealing lip on the path of foreign matter entering the seal assembly. A thrust bumper is formed in the labyrinth gap and defines a gap width by its own height during the assembly process. The rotating device may be a hub unit of a vehicle or any rotating machine with a rotor and a stator as core components. The rotating equipment adopting the present seal assembly can obtain significantly improved sealing performance, and thus is fully adapted to severely polluted or extremely humid working conditions.
