RAILWAY BEARING CONTACT SEAL DESIGN Russian patent published in 2023 - IPC F16C33/76 

FIELD: mechanical engineering.

SUBSTANCE: claimed device comprises an inner seal and an outer sealing lip; the inner seal and the inner ring of the bearing are assembled with each other by an interference fit; the outer sealing lip and the outer ring of the bearing are assembled with each other by means of an interference fit; a gap is left between the inner seal and the outer sealing lip to allow rotation; the specified inner seal comprises a bent part, an internal mounting part and a side reflective part; said inner mounting part is fitted on an outer wall of the bearing inner ring and connected to the bearing inner ring by an interference fit; the inner mounting part with the side closer to the roller is bent outward sideways to form a bent part; the inner mounting part and the folded part are arranged at an obtuse angle relative to each other; the inner mounting part with the side remote from the roller forms a side reflective part.

EFFECT: sealing efficiency is achieved and the friction moment is low.
