ABSTRACT:
Slinger seal assembly for sealing an annular space between two relatively rotatable members, i.e., an inner member, such as a rotatable shaft, and an outer member, such as a stationary housing. The slinger seal assembly shown and described includes a first rigid metallic outer case member which is frictionally supported on the housing and which extending inwardly toward the shaft, and an elastomeric shaft seal supported on the inner end of this outer case member. The slinger seal assembly of this invention also includes a slinger, which is frictionally supported on a shaft member, in this case a flange at the outer end of the shaft and rotatable with the shaft, for securing a further shaft. The slinger seal assembly further includes a second thin, generally annular rigid outer case member which is frictionally supported on the housing and which extends radially inwardly therefrom, and a second sealing element, or slinger seal, which is supported on an outer end of the slinger and is in sealing engagement with the second outer case member. The second outer case member and the slinger seal enclose a cavity surrounding part of the shaft seal which was previously open to dust and dirt, thereby appreciably reducing the amount of dust and dirt which reach the shaft seal and prolonging the life of the shaft seal.
