Patent number: 10995860Abstract: A seal assembly for sealing between first and second tubular members includes an annular seal body disposeable within an annular gland between the tubular members and formed of a generally compressible polymeric material. The seal body has a first axial sealing surface disposed against a first tubular member end surface, a second axial sealing member disposeable against a second tubular member end surface and a recess(es) defined partially by an angled activation surface. An annular backing ring formed of a substantially rigid material is disposed the body recess to couple the backing ring with the seal body. The backing ring has an outer axial end disposeable against the first member end surface to prevent radially outward displacement of the portions of the seal at the first member end surface and is biased axially toward the first member end surface when compression of the seal body displaces the activation surface axially.Type: GrantFiled: May 29, 2019Date of Patent: May 4, 2021Assignee: AKTIEBOLAGET SKFInventors: Daniel Paul Hurst, Tadd McBride, Tyler James Ryther, Wolfgang Swete

Patent number: 10030776Abstract: A seal device for sealing in a liquid medium includes a first seal assembly disposed on a primary side facing the medium and configured to seal a stationary component with respect to a rotatable component, a second seal assembly disposed on a secondary side facing away from the medium and configured to seal the stationary component with respect to the rotatable component, and a sensor connected to a volume located between the first seal assembly and the second seal assembly and configured to detect a change of a moisture level in the volume. The stationary component further includes a bore located axially between a contact surface for the first seal assembly and a contact surface for the second seal assembly, and the volume is connected to a pressure tank by the bore.Type: GrantFiled: May 27, 2015Date of Patent: July 24, 2018Assignee: AKTIEBOLAGET SKFInventors: Michael Baumann, Christian Kogler, Wolfgang Swete
