Zusammenfassung:	The utility model relates to a new oil sealing device used for improving oil sealing effect, which belongs to the improvement of the oil sealing device of hydraulic machinery. The utility model has the advantages of high reliability and long service life. The utility model is characterized in that guiding oil grooves are added on the central parts of the surfaces of the inner and outer circles of the supporting rings of a primary structure, and the guiding oil grooves are communicated by a plurality of guiding oil holes. The pitch of two inclined planes of the upper parts of the guiding oil grooves is the same as that of the sealing rings. The materials of the sealing rings are changed into polyurethane used for the oil sealing of the hydraulic machinery.
