Abstract
A seal assembly, for maintaining a seal condition between a housing and a rotary shaft extending from the housing, it accommodates a significant degree of non-orthogonal alignment between the housing and the shaft. The seal assembly includes a rotary seal member affixed to a rotary shaft, and a stationary member surrounding the shaft and including an internal bore having a contact surface. An annular, stationary floating member surrounds the shaft and is exposed in the internal bore. The floating member includes a surface in sealing engagement with the rotary seal member. An annular slip ring is disposed in the internal bore, and in contact with the floating member and the contact surface. The slip ring provides an articulated link between the floating member and the contact surface of the stationary member, by virtue of being radially displaceable along a rear surface of the floating member.
