Abstract

Improvements introduced in hydrodynamic seals for shafts of the type having a rigid outer box for contact with the bore, provided with an internal radial flange, a sealing element made of polytetrafluoroethylene, a gasket and an inner box equipped with an internal radial flange, according to of which said sealing element is a thin tablet-like washer with an outer diameter adapted to make a loose fit within said outer case and an inner diameter adapted to make an interference fit on a shaft, said inner diameter of said shutter element die cut or cut on an axial side to provide hydrodynamic means arranged to return oil from the air side of said gasket to the oil side of said gasket when said shaft is rotated, said gasket being intended to be interposed between said radial flange of said box and outer and the axial periphery of said shutter element, said inner box being housed within said outer box and retained by it to crush said shutter element and said gasket between said radial flange of said outer box and said radial flange of said inner box in relation leakproof and without rotation between them.
