Bearing protection device

In combination with a housing including a wall portion having a shaft opening formed therethrough and a shaft journaled from said housing including one end loosely extending through said opening, a bearing protector, said protector including relatively rotatable inner and outer annular stator and rotor components, said stator and rotor components including radially overlapped and axially spaced radially inwardly and radially outwardly directed, respectively, circumferential fins defining a gap seal therebetween, said stator component including an outer periphery press fit in said opening and further including first outer circumferential seal means adapted to establish a fluid tight seal with said opening, said rotor component including an inner periphery adapted for at least snug fit on said shaft and further including second inner circumferential seal means adapted to establish a fluid tight seal with said shaft, said first and second seal means both being disposed between the opposite axial ends of said opening and said stator and said stator and rotor having major portions of the axial length thereof disposed between the opposite axial ends of said opening, said stator and rotor components including inner and outer ends, said radially inwardly directed fin being disposed inwardly of said radially inwardly directed fin, said inner end of said stator component including an inwardly directed annular flange radially inwardly lapped over the inner end of said rotor component, said stator component outer periphery, adjacent the outer end of said stator component, projecting outwardly of said opening and defining an outer cylindrical seat surface, a shroud including an annular outer wall, the outer peripheral portion of said outer wall including a cylindrical axial extension, said cylindrical extension including an inner cylindrical seat surface pressed fit axially over said cylindrical seat surface with said outer end wall at least substantially abutted against said outer axial end of said rotor component, said stator component including at least one additional radially inwardly projecting circumferential fin spaced axially inwardly of the first mentioned radially inwardly projecting fin of said stator component and defining a radially outwardly tapering V-shaped void between said radially inwardly projecting fins, and said additional fin including a passageway therethrough extending axially of said stator component and disposed in said radial plane.
