BEARING SEAL Russian patent published in 2013 - IPC F16C33/78 F16C41/00 F16J15/32 

FIELD: transport.

SUBSTANCE: bearing seal of gland seal type seals bearing assembly of vehicle wheels and has magnetic position sensor to determine rpm of such rotation side component as a wheel. Bearing seal contains the first slinger element (7) having cylindrical portion (7a) installed on rotation side component (element of inner ring (2)) and part of outer flange (7b) extended from one end of cylindrical portion of the first element (7a), the second slinger element (8) having cylindrical portion (8a) installed on the part (7a), and part of outer flange (8b) extended from one end of the part (8a), core element (9) having cylindrical portion (9a) installed on element of immovable side (element of outer ring (3)), and inner flange (9b) portion extended from one end of part (9a), element (10) sealing edges of immovable side and attached to core element (9) and having sealing edge (10a) being in resilient slipping contact with element (8), element (11) sealing edges of rotating side and attached to element (8) and having sealing edge (11a) being in resilient slipping contact with core element (9), and ring multipole magnet (12) attached to outer flange (7b) portion. The element (7) has an outer flange portion the outer diameter of which is greater than diameter of outer flange portion of element (8). The magnet (12) is attached to part (7a) of element (7) so that its end in radial direction encompasses outer peripheral portion of part (7a) of element (7).

EFFECT: creation of bearing seal of gland seal type having magnet position sensor for rotation inside ring which can essentially provide mounting and formation width of magnet position sensor.
