发明名称 Self aligning split mechanical seal employing a selectively engageable axial biasing assembly
摘要 A split mechanical seal for mounting to a housing containing a rotating shaft comprising a gland assembly configured for mounting to the housing and forming a chamber, where the gland assembly includes a top surface having a gland groove formed thereon. The gland groove is formed at least in part by at least one raised wall portion that extends axially outwardly from the top surface. The seal also includes a stationary seal ring having a groove or recess formed in an inner surface.

主权项 1. A split mechanical seal for mounting to a housing containing a rotating shaft, comprising a gland assembly configured for mounting to the housing and forming a chamber, the gland assembly having a housing that includes an axially outermost top surface having a gland groove formed thereon, wherein the gland groove is formed at least in part by a plurality of circumferentially spaced apart, discrete raised wall portions that extend axially outwardly from the axial outermost top surface, and the axially outermost top surface further has formed therein a plurality of spaced apart, discrete cut-out sections formed into the top surface and extending axially inwardly relative to the top surface and relative to the raised wall portions, wherein the cut-out sections are sized and dimensioned for seating at least a portion of a biasing clip assembly, and wherein the plurality of cut-out portions are alternately disposed between the plurality of raised wall portions within the axially outermost top surface, such that one of the plurality of cut-out sections is disposed between at least two of the plurality of raised wall portions, a stationary seal ring seated within the chamber of the gland assembly and coupled thereto, the stationary seal ring having a sealing surface and an opposed axially outer top surface, a holder assembly disposed in the chamber and positioned so as to be in a cooperative sealing relationship with the gland assembly, the holder assembly defining a space and capable of rotating with the shaft, and a rotary seal ring disposed within the space of the holder assembly and is coupled thereto.
