ANGLED RADIAL LIP SEAL ASSEMBLY

A seal assembly for sealing an annular space between a shaft and a housing includes an annular case coupleable with the housing or the shaft and an annular seal member having a sealing surface centered about a centerline. In certain constructions, a coupler is configured to connect the seal member with the case or to connect the case with the housing such that the seal member is positioned with the sealing surface centerline intersecting or skew with respect to a central axis when the seal assembly is installed about the shaft. In other constructions, the seal member has an angled end providing the angled sealing surface. Thereby, the centerline of the sealing surface defines an angle to the central axis having a value of at least one degree, and the sealing surface engages the shaft outer surface to define an elliptical sealing interface extending circumferentially about the central axis. 一种用于密封轴与座之间的环形空间的密封组件包括：环形壳体，可与所述座或所述轴联接；以及环形密封构件，具有以中心线为中心的密封表面。在某些构造中，联接件被构造为将所述密封构件与所述壳体连接或者将所述壳体与所述座连接，使得当所述密封组件绕着所述轴
