Abstract

Seal arrangement for the sealing of a rotatable shaft extending through a bore in a housing wall includes a seal ring which has at least one sealing lip of elastomeric material for sealingly engaging the shaft along its outer circumference, first and second stiffening rings, an elastic intermediate coating and an anti-friction bearing. The first stiffening ring is L-shaped in cross-section with a radially outwardly directed first leg and an axially extending second leg. The anti-friction bearing is fitted in radial direction between the shaft and the second leg.
The sealing lip is fixed to the first leg. The second leg at least partly overlaps and tightly engages an outer ring of the anti-friction bearing and is surrounded on the side directed towards the bore wall by the second stiffening ring. The inner ring of the anti-friction bearing is supported on the shaft and the outer ring is retained by the second leg. The coating is made of an elastic, rubbery material which extends intermediate the first and second stiffening rings and over the second leg extends in radial and axial direction beyond the second stiffening ring subsequent to manufacture for improved sealing at the bore wall. That portion of the coating which extends in radial direction beyond the second stiffening ring subsequent to manufacture is compressed upon insertion of the seal arrangement into the bore.
The second stiffening ring is radially stressed so that it forces against the bore wall to retain the seal arrangement in the bore by friction during the intended use. The seal arrangement has improved operating characteristics over a long service period, improves the guiding of the shaft in the region of the seal and provides for the insulation/damping of vibrations of the rotating shaft during use.
