BUILT-IN SLOTTED CONTACTLESS SEAL FOR RADIAL BALL BEARING WITH REVOLVING OUTER RACE Russian patent published in 1998 - IPC

Abstract RU 2123625 C1

FIELD: mechanical engineerings; manufacture of ball bearings, mainly radial bearings with revolving outer race and fixed inner race. SUBSTANCE: built-in slotted contactless seal is made in form of rubber sealing ring reinforced with metal washer with radial circular sealing jaws and special circular groove where effect of hydrodynamic oil seal occurs during rotation of bearing under action of centrifugal forces and friction forces of lubrication against structural members. Hydrodynamic oil seal shuts off slotted section of seal, thus enhancing efficiency of seal as a whole. EFFECT: enhanced efficiency of sealing. 2 cl, 3 dwg
