Patent number: 5984313Abstract: A sliding ring seal includes a counter ring and an adjusting ring configured as a buttress. The counter ring and the adjusting ring are interconnected in a manner that does not allow for relative rotation, and they enclose a shaft to be sealed, also in a manner that does not allow for relative rotation. At least one sealing ring made of an elastomeric material seals the counter ring and the adjusting ring with respect to each other and with respect to the shaft. A sliding ring is joined to a housing and is sealed with respect thereto by means of at least one further sealing ring. The sliding ring is joined to the housing in an axially resilient manner that also does not allow for relative rotation. The counter ring and the sealing ring respectively include sealing surfaces that contact one another sealingly under an elastic preload. The sealing rings are arranged, sealingly and under the elastic preload, in a corresponding installation space.Type: GrantFiled: May 22, 1997Date of Patent: November 16, 1999Assignee: Firma Carl FreudenbergInventor: Reinhold Kraus

Patent number: 5984312Abstract: A sealing device comprises a slide ring and a counterring having sealing surfaces, the slide ring and counterring contacting one another under axial prestressing in a sealing manner and capable of rotating relative to one another, the counterring and a substantially L-shaped engaging ring being interconnected, the engaging ring being affixed to a shaft to be sealed, and the counterring and the engaging ring being sealed relatively to each other by a sealing ring. The counterring contacts a radial segment of the engaging ring and surrounds an axial segment with radial clearance, and the sealing ring is sealingly arranged, under elastic prestressing, in the gap formed by the clearance. The counterring has an inner peripheral surface which forms an angle .alpha. of about 0.5.degree. to about 60.degree. with an axis of rotation, and the radial clearance in which the sealing ring is arranged is greater on the side facing the radial segment of the engaging ring than on the side facing the slide ring.Type: GrantFiled: September 15, 1997Date of Patent: November 16, 1999Assignee: Firma Carl FreudenbergInventors: Armin Hintenlang, Klaus Schafer, Reinhold Kraus, Kurt Ewald, Andreas Jaekel, Rolf Weis, Erwin Schafer, Bernd Stichler

Patent number: 5964466Abstract: A sealing device comprises a slide ring having a sliding surface and a counterring affixed to a shaft, the sliding surface of the slide ring sealingly contacting the counterring and capable of rotating relative to the counterring, the slide ring, on a side facing away from the sliding surface, being sealed relative to a retaining ring by a sealing element of elastomeric material, the retaining ring being biased by a compression spring away from a housing which has an essentially C-shaped cross-section open in the direction of the slide ring. The sealing element is constructed as a ring-shaped bellows and has an essentially N-shaped cross-section with a first radial segment and a second radial segment which are connected by an axial segment. The first radial segment sealingly contacts an end face of the slide ring facing away from the sliding surface, and the second radial segment sealingly contacts an inner segment of the housing.Type: GrantFiled: September 15, 1997Date of Patent: October 12, 1999Assignee: Firma Carl FreudenbergInventors: Armin Hintenlang, Klaus Schafer, Reinhold Kraus, Kurt Ewald, Andreas Jaekel, Rolf Weis, Erwin Schafer, Bernd Stichler
