Abstract:
A sealing arrangement, for sealing of a radial gap between relatively rotatable inner and out components, whereby the inner component is rotational about an axis of rotation and the outer component is coaxially arranged around the inner component. The sealing arrangement comprises: a dynamic seal part mountable to the inner component; a static seal part mountable to the outer component; and first and second labyrinth seals, each being formed by a gap between at least one set of opposing surfaces on the static and dynamic seal parts, and a lip seal arranged radially between the first and second labyrinth seal. The lip seal comprises a sealing lip connected to the dynamic seal part and bears against a radially oriented counterface on the static seal part. The sealing lip has a longitudinal extension in a radial cross section that extends towards the rotation axis at an angle between 10° and 80°.
