| 摘要 |
One of two coaxial races of a ball or roller bearing is provided near an edge thereof with an internal annular groove into which a peripheral lip of a plastically deformable sealing ring of generally L-shaped half-section is forced by camming engagement with an axially more inwardly positioned annular member resting against a transverse shoulder of that race. The annular member may be a lip seal in contact with the other race or may be part, together with the deformable ring, of a labyrinth seal including at least one further ring mounted on that other race. |
