Abstract:
1. A seal seat assembly for a shaft of an appliance, the seal seat assembly comprising: an annular seat component including a first inner surface defining an inner diameter, said seat component configured to be disposed around the shaft of the appliance with a first clearance between said seat component inner diameter and the shaft; and a ring component including an annular first portion operable to have a sealed engagement with the shaft and a second portion extending axially from a first end surface of said first portion, said second portion including a flange extending radially outwardly therefrom, said flange having an outer diameter and a radial thickness, said ring component configured to receive said seat component between said flange and said first portion and couple said seat component to the shaft, said seat component having a second inner surface spaced radially outward from said first inner surface and arranged to engage a radially outermost surface of said first portion of said ring component; wherein said flange outer diameter is larger than said seat component inner diameter and said flange radial thickness is configured to be larger than said first clearance between said seat component inner diameter and the shaft, said ring component thereby forming a mechanical lock operable to inhibit axial movement of said seat component relative to said ring component when said ring component couples said seat component to the shaft.
